fantasy au ; eventual smut 🔞

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
2
of the ceremony and the union of their kingdoms.

the first thing katsuki notices about his soon-to-be-mate is that he's /tiny/. the omega barely came up to his chin and was overall small. katsuki can't help to scrunch his nose at the realization because, well
3
his kind is known for being big and sturdy, specially in their, ehem, southern regions…

he’s worried okay? he doesn’t wanna hurt his very fragile looking fiancé on the very first night they spend together.
4
did the maids prepare him? does he know? does he /want to/ mate that night? did-

“lord bakugou,” the delicious-smelling little thing says, getting all of his attention.

his face is covered by a thin veil, decorated by the typic symbols and colors of his people, matching his
5
carefully tailored bridal attire.

the omega offers him a small smile behind the fabric. “you’re even more handsome than the forbidden tongues said,” he whispers above the preach going on with the ancient wedding ritual.
6
the ceremony is reaching its halt, and they’ll soon have to vow and see each other for the first time, sealing their destiny with a first kiss and inaugurating the celebrations for the night.
7
the barbarian’s eyebrows rise in surprise to his bride’s bold words, but he’s quick to retort. “katsuki,” he says. “my wife may call me by whatever name he chooses.”

the omega huffs what sounds like a soft laugh, and lightly tilts his head down in agreement.
8
“very well… kacchan,” the omega replies, voice smooth like honey. he turns to the preach, and katsuki notices the sun has set in the horizon behind them.

it’s time.

“i hope you’re as pleased with your queen as i am with my king,” the omega purrs, taking a step closer so
9
the barbarian can lift the veil, and the last rays of sunshine can shower their faces, blessing their union.

when the preach consents, katsuki does, no hesitation. he grabs the fabric and throws it back, revealing his mate’s glinting eyes and gentle smile.
10
the alpha sees the face of his queen for the first time. he immediately knows the gods have rewarded him and his kingdom with this divine creature, and his alpha agrees.
11
beautiful tanned skin splattered with freckles over chubby, healthy cheeks. perfect cheekbones, and big, viridian eyes, same shade of his unruly hair, that only look at him. his button nose twitches after a few minutes pass. izuku blinks
owlishly at him, eyes sparkly, loving.
12
dragons like shiny things. they hoard jewels, gold, treasures.

katuski will never want anything more than this pair of emerald eyes looking at him. he's found the most gorgeous gem any treasure has ever held in the omega who just accepted him as his king and husband, his alpha.
13
katsuki kisses him, placing his big warm hands on his jaw and petting across his neck and earlobes as he brings him closer, enveloping him in his warm. the omega sighs against him and melts in his chest, purring softly in contentment.
14
with that, they become husband and wife; queen and king.

if everything goes well, that night they would also become mates, and hopefully Izuku can get with child —if he desires to, that is.

the party is marvelous, the night is alive and the starts shine brightly above them.
15
they dance around the fires, toast with their sweetest mead and eat the deer katsuki had hunted as a wedding offering for izuku and his parents; traditionally demonstrating how good of a provider he was.
16
it’s late into the night when they leave to their chambers —pushed inside, better said, between wolf whistles and giggles from their friends. it makes his omega blush, and Katsuki’s never seen a prettier shade of pink.
17
they're expected to mate that night. people will look for a bite mark adorning izuku’s neck the next morning, and for signs of a growing belly during the next months.

katsuki, however, doesn't give a shit about what he's supposed to do, he never has and never will.
18
for the first time since he met his bride that morning, izuku looks shy. his lips are pursed and his hands are politely crossed over his gown, pink blush turning crimson. his eyes are set low in the polished floors of what used to be katauki’s room, avoidant.
19
that won't do.

“look at me,” the alpha commands, quietly enough not to startle him. izuku complies, slowly turning his eyes on him. katsuki finds his knees getting weak under the forest-green gaze of his wife, dense and captivating, but gentle as summer rainfall over hot skin.
20
“we don't have to do anything you don't want to,” he assures, taking a step forward. “i can sleep somewhere else.”the omega holds in a breath and frowns, but still allows his husband to get close.
21
his welcoming, pleasant petrichor scent changes ever so slightly into a more bitter one, like a dragon’s breath after spitting fire. his alpha doesn't like it.

izuku gulps, dejected. he holds his eyes up and asks, “does… my husband not desire me?”
22
“that's not what i said,” the alpha replies, almost offended. “i don't want you to think you have to do anything to please me. you do that just by letting me look at you,” the king mutters, daring to bring his hand to his queen’s face and letting his knuckles graze his cheekbones
23
the omega leans into the touch and closes his eyes for a second, and it makes katsuki smile. he trusts him.

izuku opens his eyes and stares at him, not pulling away.

“i want to,” the little thing says, scent turning sweet and mind-numbing for the man before him.
24
the omega places his small hand on top of the big one still on his face and smirks. “i want you, my king.”

a deep rumble comes from the alpha’s chest. he grabs his wife’s wrist and softly presses his lips to his pulse, feeling it accelerate under his wanting mouth.
25
he lets his fangs scrape the skin. izuku gasps.

now’s his turn to smirk. “let it be known that whatever my queen desires, he will have it.”

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
27
the omega’s pupils dilate, and he chirps. katsuki chuckles.

“whatever i want?” he mutters, unsure, dazed by the teeth on his skin and new-found interest in his husband’s words.
28
katsuki knows then he will spend the rest of his life fulfilling all of his wife’s whims if it means his beautiful face will light up like that, all excited and with a child-like wonder.

he wants to devour him. his omega is so adorable.
29
“what kind of alpha would i be if don’t dote on my omega?” he says.

from what he knows of izuku’s kingdom, omegas are usually treated as mere game cards. cherished and all, but still viewed as pretty tools to use when needed.
30
the ones belonging to the royal families served as bridges between monarchies, destined to grow up being promised to alphas in power positions to create alliances for their territories and bear their heirs.
31
that's supposed to bring honor to them and their families because, after all, that’s all they could be good for: wives, mothers, and trophies. an archaic thought for the dragon people, but still common in many other places.
32
katsuki highly doubts omegas are ever asked what they want outside his kingdom’s borders.

izuku probably wasn’t.

something in izuku’s expression falls to gloominess. it's fast, and almost unnoticeable because in less than a second his face goes back to normal.
33
the king stares, curiosity awakened by the omega’s sudden change. “you don’t wanna be doted on?”

“of course i do, kacchan,” he gently answers. the prince nuzzles against the big barbarian hand that makes his face look small in comparison, but his eyes are not glinting anymore.
34
katsuki feels like he’s been robbed of all joy. “all omegas like to be taken care of by their alphas.”

said alpha hums, gives one last stroke to the apple-red cheek, and walks away. izuku blinks twice, most likely wondering about his husband’s odd behavior for a wedding night.
35
“allow me to rephrase my question, then,” the man says.

he moves to the big window occupying most of the bedroom wall, grabs the heavy velvet curtains and opens them to reveal the shimmering night sky that blends with the kingdom lights below.
36
the whole kingdom is celebrating tonight, fires and cheers can be heard and seen all around. their king has taken in a bride and their people would finally have a queen again. the sight is breathtaking, and katsuki takes pride in the happiness spilling down the streets.
37
despite what people thought when he took the throne, the alpha brought them peace and satisfaction, and he will ferociously defend it until the day he dies.

he may feel more comfortable holding a sword and conjuring magic in battle, but the crown suits him just as good.
38
he looks back to the omega and offers his hand, inviting him to join him. he does. the alpha smells curiosity, and his mouth waters when he gets a closer look at the shiny scent gland on the slender neck, no longer covered by the veil.
39
izuku notices and shifts on his feet, watchful, and keeps a respectable distance that katsuki doesn't exactly appreciate. but he can't blame him, he knows the kind of education omegas receive outside his territory, so he just clenches his jaw and focuses on what he wants to say.
40
“do you see that?” he points down where the fireworks are still going off and the music is loud as the dragon’s roar. izuku nods, eyes glued on the horizon for a moment before he looks back at the alpha.
41
“they're happy,” he muses, a small smile creeping on his lips. his cheeks look so chubby katsuki has to resist the urge to bite.

“it's because of you,” the alpha says.
42
his already big eyes widen even further, and he glances between them and the window like he doesn't understand. “me?” he breathes, touching his chest.“isn't because their king got married?”
43
“yes, but it's not me the one they're celebrating for. what colors are the fireworks?” he asks, pointing at one of the big lights illuminating the sky before them, showering everything in….

“green,” his wife whispers, amazed and consumed by the glow around them.
44
“in our culture, green is the color of omegas,” he explains. “it means life, growth, peace, and good luck. you happen to particularly match it, too.” he laughs, petting his hair and stroking his thumb under his eye. “they're grateful for you. and so am i, my beloved queen.”
45
izuku's eyes fill with tears. katsuki wipes them as a few of them fall. the alpha releases an overpowering smokey scent that relaxes the omega clinging onto him for dear life now, and croons when plump lips stop trembling.
46
fondly, the barbarian takes off his cloak and places it on the omega's dainty shoulders, drowning him in the heavy-scented furr.
47
the little thing looks at him with the face of what could only belong to an angel, and it makes katsuki curse in his traditional tongue because of the wave of affection that washes over him.

oh, the power his queen already has over him. and he doesn't even know it.
48
“everything that's mine now is yours. my people, my land, my soul,” he mutters, placing a possessive hand on the back of the omega's unmarked neck –he shivers in response. “i'm going to ask again. what do you wanna be, izuku?”
49
“I want to be your omega,” he instantly replies. his fingers tight around the cloak, knuckles turning white. “it's an honor, my king.”

his brows are furrowed, and his scent is uneasy again, like the air before a storm. so katsuki pushes a bit harder on the tender spot.
50
“If that is all your heart longs for, then i respect you deeply for it. being an omega, a queen, is not easy work. but that is not what i meant, darling” he says, with the patience that all of his years on the throne dealing with political issues have given him.
51
but this isn't politics, this is his mate. his patience is loving, caring.

“if you didn't have the burden of your blood upon you and your duties did not concerned you, what would you /chose/ to be?”

the answer leaves the omega’s lips faster than a fire goes out. “a knight.”
52
a firework explodes, people thunder in excitement.

katsuki’s lips slowly curl into a delighted grin. “a knight?”

the omega looks at him in horror, pailing, shaking his head. “please, don't mind my foolish fantasies, it's all they are. i know i could never-”
53
“do you have any combat training?” the alpha asks.

izuku quiets and searches for any trace of mockery in his voice. he finds none. shyly, he dares to nod. “i do.”

“who trained you?”

“my father.”

“the king all might trained his only omega son?” he asks, visibly surprised.
54
izuku gulps and nods again. “my mother never approved of it, but i begged him for years to allow me to learn. we did combat training almost every night, after i was done with my duties and all of my omega lessons.”
55
“are you good?” the alpha teases, but is completely serious in his question.

“i've been in the field,” the omega confesses. “the war, two years ago.”

that earns him a gasp from the alpha, who has to take a step back to look at his wife better, in a totally different light.
56
gods.

he's so small, and seems so fragile. katsuki's alpha almost wants to faint thinking he was ever in danger like that. his alpha commands him to protect him, but damn if he isn't thrilled.

“prove it to me.”
57
“what?” the doe-eyed omega chokes, using the cloak as a shield between them. “how?”

“you can either try to pin me down or be more creative, your choice.”
58
izuku stays still for what they both feel like an eternity but must be less than a second. debating himself, his eyes wander back and forth between the alpha, the window, and the floor until he suddenly straightens his posture and drills holes into the alpha's thick skull
59
with the intensity of his determined gaze.

with one hand, he begins fumbling with his garments while he keeps the cloak wrapped around his figure. he grunts and growls under his breath, and katsuki thinks is the most charming thing he's ever seen.
60
he crosses his arms over his naked chest and waits, amused.

after a few minutes, the omega seems to be done with whatever he was doing below the heavy cloak. he stares at the alpha before him, and his breath hitches, his scent spikes, anxious.
61
“i will understand if you do not want me anymore after this. you don't have to touch me. i'll blame myself tomorrow and pack my things. i knew what i was getting into when i disobeyed my parents' orders, and if this is my consequence, then i'll accept it.”
62
the king frowns and sends him a questioning glare. what the hell is this omega talking about?

“just… thank you, kacchan,” he mutters. a melancholic, honest smile quirks his mouth up, “for asking me.”
63
he lets the cloak fall, and everything he was wearing underneath too. the fabric pools at his feet, and he’s naked.

the king, for the first time since he was very young and inexperienced, is left completely speechless.

the room falls into silence.

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
65
katsuki's seen bare omegas before. the dragon people were not precisely known for being modest with their bodies.

that's why izuku stood up so much from the second he set foot outside the carriage.
66
his royal garments were meant to show he was promised and soon to marry. lace and velvet in turquoise and gold colors covered him from head to toe; only his hands and face could breathe, keeping him flushed and uncomfortable.
67
as pretty as he looked, it seemed like torture. the alpha could tell by the sweat on his brow, and his hands ached to relieve him, to strip him nude and let him enjoy the warm breeze instead of choking on it.
68
but he should have known something was different when he saw his skin was tanned and golden, beautifully kissed by the sun.

in other kingdoms, omegas in the mating age were kept sheltered, hidden under fabrics, and shielded behind walls from lustful alpha eyes.
69
especially royal ones, who were precious and couldn't risk being damaged. their value resided in their utility for their kingdom and, sadly, that translated into their purity.

barbarians don't believe in that, but he knows what to expect from a foreigner.

or so he thought.
70
the body before him is not the one of an omega who spent his life sitting around in pretty dresses learning to drink tea and engage in polite conversations.
71
the delicate wedding lingerie covered little to nothing, and was more diamonds and stones in a golden string than a real piece of clothing.
72
they hang over the delicious curve of his hips and breasts, and the most striking stone strategically rests on his womb, above his cunt, suggesting, alluring.
73
to any other alpha of his kind, this would have been distracting enough to not pay attention to the rest of his body and get straight to the mating; clouded with lust and influenced by alcohol, a dragon would have been blinded by the jewels.
74
but katsuki is the king, and he knows better; he’s too well aquatinted with how warfare leaves a mark on virgin skin.

it's a poor attempt to distract him from seeing the blotches all over him; for katsuki to mark without properly looking at his wife first.
75
the pretty little thing that seemed fragile enough to be swept away by the wind is nowhere to be seen, and in his place, there is lean muscle and scar tissue, a few tattoos, and old sutures.
76
the only soft parts of his body that katsuki could see were his inner thighs and tummy, but that's just his omega nature being stubborn.

traces of violence tinge a path where only delicate touches should have been, it makes the alpha's fangs sting.
77
the omega clenches his jaw and keeps shameful eyes low on the floor, chest heaving. he places one of his hands over his right shoulder, where one of the biggest scars makes its way across his arm up to his elbow, still pink and angry but definitely not recent, just poorly healed.
78
what captures katsuki's attention, however, is the hail of freckles merging around it, coming down from his cheeks and neck and accentuating around his shoulders, smoothly fading through his chest and biceps.
79
izuku realizes where the alpha's vision lands, and he gulps before rasping, “mom always told me not to be under the sun for too long because they would darken. i guess at the moment it didn't seem as important.”
80
“is it important now?” katsuki mutters, staring fixedly at them.

“welll,” the omega starts, abashed, “i suppose it doesn't matter anymore. the freckles are barely visible under all the scars.”

izuku's scent is not even distressed anymore, but hopeless, blue.
81
by the wobbling of his mouth and the tremor in his voice, katsuki knows he's -poorly- holding back tears. the grip of his crooked fingers on his shoulder is so forceful that the skin starts turning red around them,
82
and he's trembling despite the room being warm by the night breeze flowing through the window.

katsuki wants to embrace him, shove him against his chest and lick under his chin until his face loses all its sadness, but he doesn’t know if izuku would want that yet.
83
so instead, he says, “that's a shame, then. they're so delightful.”

the omega's head whips up, bewildered.

“my- my freckles?” his wife stutters.
84
katsuki nods. “yeah. we have a saying here for them,” he says, approaching the omega with the same caution he would a fawn. “whoever possesses them was sprinkled with gold dust by the fairies in their sleep. you know what that means?”
85
izuku shakes his head as he watches his husband get closer, utterly still if it weren't for his labored breathing.

the alpha catches his lower lip between his teeth and brings his hand to stroke the marred arm,
86
tracing the raised border with the tip of his calloused fingers, gentle as falling leaves in the autumn. the omega trembles under his touch, following his moves with wide eyes.
87
“it means a dragon is meant to find you,” the barbarian whispers. they're so close he can feel the omega's quick breaths meeting his chest, ruffling the feathers attached to his necklace.
88
“to treasure you,” he caresses tear-stained cheeks, holds them, and forces izuku to stop trying to hide. “to love you.”

“kacchan,” he whimpers, staring at him with crystalized eyes, face scrunched with distress. “don't give me hope, please.”

katsuki frowns. “hope?”
89
“i want to be chosen,” he says, looking right into the alpha's eyes. “i've always known any alpha i was promised to for marriage would have to settle, unable to refuse me because of my family's name and power.
90
and it pained me,” his voice breaks, and the alpha feels it in his veins as an animal need to soothe. “to know love would never meet me because even if i ran away from my destiny, who- who would want an omega like me?” 

“an omega like you?” the barbarian questions, glaring.
91
“strange,” izuku snaps, clenching his fists. “who wishes for adventure before pups, for knowledge instead of jewels, and can hold a sword better than a needle. who… prefered going to war before taking a husband,”
92
he whispers, letting his head fall onto the alpha's chest as he takes in a deep breath, tickling the barbarian with curly hair.

the king blinks, being almost at a loss for words.

they have more in common than he tought.
93
hesitantly, katsuki takes him by the shoulders and gives him a reassurance squeeze, and when izuku doesn't stop him he lets out the air he didn't know he was holding.
94
“is that why you enrolled?” he softly asks, stroking warm skin with his thumbs, indulging in his need to comfort the omega. “to escape?”

izuku grimaces and bites his lips, “no.”

“then be honest with yourself. why did you do it?”
95
“our soldiers were dying,” he says between his teeth, looking up at him. “dad couldn't fight, he was too weak. i was the one who inherited his knowledge, his secrets, the same that defeated our enemies so many years ago.
96
how was i going to stay hidden in a castle while our people gave their life to protect our home?”

the alpha stares at him, serious as ever. “you weren't hiding from a marriage, izuku. you were defending your kingdom.”
97
the omega’s breath hitches, but he doesn't look away. “i wasn't ready to marry.”

“back then, neither was i,” katsuki replies, lips quirking into a slight smirk. “guess we should be thankful then.”
98
“if i had marry then, at least  i’d be a bit more pleasant to look at for my husband,” he says with an apologetic smile that vanishes a little too fast. when the alpha raises his eyebrows at the comment, he sighs.
99
“beauty was never a quality i possessed, so scarring my body did not worry me. but now…

his scent varies between a colorful tapestry of troubled emotions until katsuki releases an overpowering bunch of strong, soothing alpha pheromones that make izuku swallow a whine.
100
the omega slumps against him, but doesn't completely relax.

/he’s keeping composure/ the alpha thinks. /stubborn thing/.

izuku breathes trough his nose, and finally decides on disclosing the fears in his heart to his awaiting husband.
101
“now that i have met you, i'm scared,” he whispers, “i thought i could face your rejection, and perhaps… i could have more freedom here, as the wife you had to take but didn't want.
102
you could have other omegas that could satisfy your desires and i'd pretend not to see, and we could live separate lives as we fulfilled our duties.”
103
the barbarian observes like only the two of them exist in the world, attentive, making the omega squirm under his burning gaze.

“is that what you wish for?” he quietly asks, “for our marriage to be one of appearances?”
104
“it's the most i thought i could aspire to,” the omega sheepishly admits. “i can't force you to love me, or to desire me like your omega.
105
i know what i look like, and i did this to myself. i wouldn't blame you, we're both tied by our responsibilities to our respective kingdoms, and that's why we are here,isn't it?” izuku breathes out a laugh, humorless and so heartbroken.
106
his mouth speaks things his body doesn't match, because everything about the omega is trying to pull the alpha closer to him; his scent, his movements, his sounds. his breath warms the king's scarred skin, and he feels it deep inside him.
107
the alpha holds him, and izuku goes slack, with his freckled face still buried in the barbarian's chest.
108
“you have already offered me so much more than i ever thought i could even dream about, but i'm- i am so selfish, my king. so, stupidly ambitious despite knowing my place, that has always been my curse.”
109
the omega peels himself away from the alpha enough to look up at him, and and it's only under the pressure of the alpha's stern but fond stare, that izuku finally breaks.
110
his face twists with frustration, and his sweet scent twinges with anger. a sob scapes his sore throat, and the sound is so distressed that katsuki thinks he could fall into madness if he ever hears it again.
111
“kacchan, you've stolen my stubborn heart. i can't- don't want to leave you,” he whines, pained and so, so small.”my omega has never called for anyone the way it calls for you, you're my alpha. if i had to leave tomorrow i wouldn't live to see another day.”
112
izuku slowly lets himself slip to the ground, letting his weight fall to his knees. the king freezes, appalled, staring down like the marble floors would open and swallow them both. the omega crouches at the alpha's feet and rests his forehead near the tip of his boots.

bowing.
113
“i love you. please, allow me to stay by your side and i promise to be anything you need. give me a chance, my king, to be not only your queen but a mate you could get to love someday and maybe-” he chokes on his words, shoulders seizing with the force of his crying.
114
he takes a deep, wet breath and tries to continue, “maybe we-”

a growl interrupts him, bone-chilling, unmistakably authoritarian, and the earth threatens to shatter.

/“enough, omega”/
115
the command echoes on the walls, making the omega flinch and whimper, immediately quieting him down. his spine straightens in mild alarm, raising himself back up again while staying in the same position.
116
the alpha drops to the floor to his shaking wife, and mirrors his position, kneeling right before him. gently, he takes the omega's wet chin between his thumb and index finger and brings his face up, meeting his watery, emerald eyes.
117
“my queen bows to one, understand?” he commands, “not even to his king.”

izuku gapes, blinking the tears away. “why?” he whispers.

“because you're my equal, and i don't bow before anyone.”

“you're kneeling,” the omega replies, then clearly repents judging by how he tenses.
118
katsuki can't help smirking. “you sure like to ramble, don't you?” 

izuku lowers his eyes again. the alpha instantly misses them on him.
“izuku,” he calls. the omega looks at him through his lashes, timid. “who ever said i didnt want you?”
119
“it's an arranged marriage,” he replies, as if it was any news to his husband, “and i am-”

“you're perfect,” the alpha interrupts. “my omega, why so little faith? don't you see i have been waiting for you all this time?”
120
the omega snaps his mouth shut and stares in disbelief. 

“the gods sent you to me, chose you be mine. the perfect queen,” he says, fondly smiling at the bewildered omega watching him with glossy eyes.
121
“you were born to be part of the dragon people, that much is clear,” he brings their foreheads together in a tender touch and whispers, “i'm so glad you are home, my sweet izuku.”
122
izuku chokes on a whimper, and new tears wet both of their faces. katsuki internally chuckles, his omega is such a crybaby.
123
“dragons are born with fated mates. when we meet them, we just know,” he kisses the tip of izuku's nose and tastes salt. “my alpha recognized you from the first moment you got out of that carriage. i'm guessing your omega recognized me, too.”
124
“i'm not a dragon,” his wife mumbles, barely audible above his jackrabbiting heart. 

“you're my mate. and i'm the king of the dragons,” the alpha firmly says. “you're different from your people because you belong here, with me.”
125
katsuki croons, and izuku purrs in response. “dragons mate for life, baby. we know no other way of loving.”

“you love me?” the omega questions, eyes pooling with blazing anticipation, scent exploding into a strong honey, herbal fragrance.
126
katsuki lets out a guttural whine, nodding desperately. “i love you,” he breathes out, slowly leaning down, tilting his face to the side. the omega realizes what he wants to do and offers no resistance.
127
contrarily, he bares his neck to him, offering him his most vulnerable spot to do as he pleases. katsuki’s inner alpha roars, proud of having won his omega’s submission.

katsuki smiles, adoringly looking at his wife. “my mate is everything my hoard was missing.”
128
a fresh wave of excited, piney omegan scent hits the alpha's nose and makes him croon again, flooding his mind with the memories of his youth when he often got lost in the forest, exploring, learning the ways of the land he would rule in the future.
129
their necks touch for the first time.

the feeling is unlike everything he's ever experienced. shudders run through their bodies, and katsuki has to take a moment to close his eyes and ground himself, pushing back the desire to bury his fangs in his omega’s neck.

a couple's first deep scenting is sacred, intense, and meant to be the initial touch of intimacy shared between new mates. a taste of what's to come, a reassurance of the bond, a promise of belonging.
132
action is katsuki's preferred language. he hopes izuku understands what he's trying to tell him.

the scent of slick sweetens the air, and the alpha needs more control than he ever thought he would when saliva starts to pool in his mouth.
133
“alpha,” izuku breathes. he feels smaller hands creeping to pull strands of blond hair between his fingers, demanding his attention, digging into his scalp.
134
his eyes are dilated, big and dark, as if heat clouded him and the omega is thirsty for whatever katsuki wants to give him, eager for his alpha to put his claim on him.
135
“omega,” the barbarian grunts out, eagerly rubbing their scent glands together, possessively mixing their scents like a madman, finally relieving the need to mark what's his so no one else can touch it.
136
izuku becomes putty in his arms and eagerly wraps himself around the alpha. the barbarian nuzzles against his scent gland and lets his mouth taste his mate's oils, quickly growing hungry, grunting and chewing on skin like a beast with no restrain,
137
holding izuku closer and keeping him there just to make sure he can't escape from his ravenous tongue.

his alpha howls, voracious, fangs growing inside his mouth and producing loads of potent venom that starts dripping down his chin.
138
it would be so easy for him to just sink his teeth into the tender neck so close to his mouth, and mate izuku right where they are, on the floor.

the tiny part of his mind that still functions rationally scolds him.

that's not the mating his queen deserves.
139
he needs to be laying on the softest fabrics, surrounded by the alpha's finest furs and blankets that he spent weeks choosing and thoroughly scenting upon the omegas arriving, in the bed that would become their nest if izuku likes it.
140
he has to be relaxed, and prepared, too drowned in pleasure and lost in his alpha's worship to notice the sting of the bite, otherwise, the experience would be painful for him.
141
“alpha, please,” the omega begs, with his big doe eyes looking hazily at him. “you smell so good, i can't take it anymore,” he babbles, letting his hands roam the alpha's biceps. “i need- kacchan, /give me./”
142
it only takes katsuki one look at him to know that the poor thing doesn't know what he needs despite desperately begging for it, but that's alright, his kacchan knows. he'll give it to him. he'll give him his every breath if izuku wants to steal it.
143
“i know baby, it's yours,” he promises, kissing his temples to distract his mouth, “everything you want, is yours.”

another heavenly wave of sugary smell hits his nose, almost knocking him out of balance, forcing him to put one hand on the ground to keep from falling.
144
instead of cool marble, his hand meets a sticky, syrupy liquid that coats his palm. when he looks down, he realizes it is izuku's slick that has started dripping down his bare legs onto the floor, creating a little puddle under him.
145
he brings his hand up and spreads his fingers against the light, mesmerized by the thin membrane of slick that appears between them.

his fingers are on his mouth before he can process what he's doing.
146
izuku chirps a sound that's half embarrassed and half impatient as he watches him with blown pupils and lets out a soft, steady purr, tempting, sensual, and meant for the alpha to react to it right away and fold before his omega's wishes.
147
the slick tastes like the sweet nectar of the forest wildflowers, and all of his favorite desserts. the thought makes his head spin from how much he likes it.
148
the alpha licks every drop of it, laps between his fingers and below his fingernails, swallows down what he can get until his fingers are clean, and suddenly it's like he's been thirsty all his life.
149
the flavor screams fertility, desire, and omega, and it's so damn good katsuki thinks he could live from this alone forever and be more than satisfied.
150
a growl reverberates in his chest, so deep and so hungry the necklaces resting on his pecs jingle. izuku, the responsive little thing, answers him with an excited set of chirps.
151
“omega, i want to taste you,” he declares, taking Izuku's face in his hands, probably looking as desperate as he feels. “can i-”

“yes.” izuku frantically nods, holding the alpha's strong, wide wrists, beautiful eyes half-lidded, pleading, “i'm yours, alpha, only yours, forever.”
152
and that's all katsuki needs to let go of all his attempts to keep his desires at bay, because why would he when his wife is begging so beautifully, looking so tasteful? from now on, he lives to please him.
153
it's like something possesses him because he barely has time to snatch the now-drenched cloak to extend it on the floor before he snatches izuku by the tights and lays him on top of it.
154
katsuki presses the omega's back on the ground, earning a high-pitched squeak, and hooks his ankles over his shoulders, pulling him towards him.
155
izuku watches him from below like a deer caught in the woods, his chest goes rapidly up and down and his scent -the little katsuki can distinguish from the slick in his hazy state- is nervous, but not frightened.
156
the alpha turns his head to kiss one of the thighs wrapped around his head, and he makes sure to playfully nibble all of the softer spots. he lets his nose follow a pattern of freckles, occasionally licking when it gets too tempting.
157
he kisses the scars there and makes sure izuku sees him paying reverence to them, and the omega can only bite his lip and purr. then he repeats the process, again and again since the scars and freckles seem to be never-ending. but he's not complaining.
158
izuku sighs a breathy chuckle and katsuki smirks, flashing his big, long canines.

“is there something funny, my queen?” he murmurs over his skin, looking at the squirmy omega with fond eyes.

he kind of gets his father now, always watching his mother with an enamored face.
159
“it tickles…” he admits, blushing furiously. “no one has ever touched me like that before.”

something possessive flares inside him at the admission, it makes him croon and puffs his chest. “how, baby?”
160
“like… like i'm beautiful,” he bites his lower lip and looks away, embarrassed. “i never thought anyone would want to touch me like this.”

“why?” katsuki growls, biting a little bit harder this time and making izuku squeal. “because you have scars?”
161
izuku nods, panting as the alpha keeps kissing. “and my muscles are-”

“haven't you heard?” katsuki
interrupts, taking the diamond chain around the omega's thighs between his sharp teeth and pulling it hard enough to break it, sending little pieces of gold and diamonds flying.
162
izuku gasps, “kacchan!”

“in here,” he continues, “we like our omegas strong,” he says, getting closer and closer to izuku's heat, where the mouth-watering scent is calling katsuki by name. “brave, smart, and mighty, just like you.”
163
“im not- ” his wife tries to argue, but it's rendered speechless by a silent cry when the barbarian leaves a kiss right on his pretty, swollen clit.
164
katsuki hooks his finger around the small piece of fabric covering his cunt and tears it away, finally leaving his beautiful omega pussy exposed for his viewing pleasure. katsuki growls, wetting his lips with his greedy tongue, not able to tear his eyes apart from his feast.
165
“you don't have to believe me now,” he rumbles, “i will show you just how much i want you,” he licks a fat stripe from izuku's perineum to his clit, collecting as much slick as he can on his tongue.
166
the omega screams and his hands fly to katsuki's hair, needing something to hold onto. “how beautiful you are, and how proud i am to be your alpha.”
167
the barbarian teases the cherry-red folds until they're so puffy and slicked that izuku opens like a flower for him, his hole fluttering at the emptiness, begging to be filled by his alpha.
168
katsuki purrs loudly, and the vibrations send waves of pleasure down the omega's body, making him shudder.

the alpha's tongue finds its home inside izuku's pussy, and he quickly establishes a slow pumping rhythm that has izuku crying in no time.
169
his clit twitches, like complaining at the lack of attention, and katsuki just can't ignore it. he pulls his tongue out of the soft cavity and izuku gives him a desperate mewl at the loss.
170
“shh, patience, baby,” the alpha grins, face sticky and shiny with slick. izuku watches him, frows burrowed and pouting. so cute. “we have all the time in the world.”
171
he blows hot air to izuku's clit and it twitches again. the omega lets out a needy whine, moving his hips in search of relief.

“kacchan, don't be mean,” he cries, fingers trying to slip down to his cunt to stop the teasing.
172
when his hands get too close, katsuki snarls at him, showing his upper fangs in a silent warning. this is his pussy now, only his, and no one can touch it without his permission, not even the omega. izuku immediately pulls them back, wide-eyed.
173
new slick pours out of him, and his scent turns needier than before.

“oh, honey, but i am,” he mutters, voice low and velvety, looking at him straight in the eye as he wets his lips with the tip of his tongue before giving a kitten lick to the bundle of nerves.
174
izuku throws his head back and arches his spine, whimpering. “but something tells me you like it.”

he seals his lips around his clit and /sucks/, stealing a loud moan out of the omega under him.
175
izuku squirms and fights the early overstimulation of his inexperienced body, clearly thorned between getting lost in the pleasure and feeling overwhelmed. makes katsuki curious.
176
“do you touch yourself, izuku?” the alpha slurs, lust-consumed, unrelentingly eating the omega out.“during your heats?”
177
izuku cries, rapidly shaking his head no, “they wouldn't let me.”

“who?” the alpha growls, attention split for a second.
178
“my maids,” he breathes out, trying to look at him but failing due to his lack of strength at the moment, “they would- ngh, give me medicine instead. omegas are not allowed to do those things without their alpha.”
179
katsuki grunts from his cunt, angered. “so they just let you suffer?”

izuku nods, tears spilling from the corners of his eyes.
180
“it hurt so bad, kacchan, every time,” he manages to look to the side and finds the alpha's eyes, molten read from hearing his omega was forced to spend his heats in pain for no reason at all.
181
when their eyes meet, the lovely freckled face of his wife scrunches in a distressed pout that ends up unraveling in a wet sob. he extends his arms to him, making grabby hands at his husband. “i needed you, alpha.”
182
the alpha's mind turns blank for everything that isn't izuku, a silent, hot protective sentiment curls inside his chest. he doesn't know how much is instinctive and how much is frustration for not having been there when his omega needed him.
183
he knows it's irrational, but most feelings are. he can’t change whatever his omega went through when he was away, all he can do is make up for it now.
184
“i'm sorry baby, i'm sorry i wasn't there. you'll never hurt like that again now that you're home. i'll make it all better.” the promise slightly soothes his raging alpha, but he knows it will be rather restless until he does something about it.
185
katsuki is a king known for keeping his promises, for being faithful to his word, as impossible as it might seem, and going through with everything he says. his omega better learn it fast.
186
he brings him closer as he readjusts himself on his knees, lifting the omega's plump ass from the ground, desperate to erase any space between them and to drown in him, to get drunk on his arousal and engrave the taste of him on his tongue.
187
“alpha!” izuku screams, supporting himself on his elbows the best he can, staring at katsuki with a wild look in his eyes. his skin glistens with sweat, blush spreads from his cheeks and down his neck, and his nostrils flare trying to calm his breath.
188
katsuki pushes his nose and tongue deeper into his cunt, and izuku gives up trying to hold himself up, letting himself fall limp and just accepting all of his husband's mouth whims. katsuki delights in his weakness, it means he's doing a good job and making the omega come undone.
189
slick hasn't stopped pouring out from his hole, and katsuki now understands what his knothead friends yapped about when they said omegas were downright addictive.

“kacchan, kacchan,” he chants, delirious, high on pleasure. “you're so amazing, it feels so good,” the omega cries.
190
and katsuki is weak for his praise, so sweet from his pretty mouth, he grunts and ruts against his back, just looking to get some relief as izuku's whines become sharper and breathier.
191
his grasp gets tighter, bruising, and he works his tongue deep and fast until the omega is shaking so violently that's hard to hold him. 

at some point, there is so much slick that it starts flowing down the barbarian's chest, covering him and izuku and everything near them.
192
“my beautiful queen, my wife, so precious, only for me,” katsuki mumbles, barely audible with his mouth so busy, more to himself than to izuku. “my omega.”

izuku screams, whole body tensing, the muscles on his belly spasming, “kacchan, wait, i feel- oh my god, ah!”
193
izuku cums, right on his tongue, squirming and crying as the alpha continues mercilessly lapping and sucking every sensitive spot in his pussy, drinking all of his release.
194
izuku just takes it, completely at the alpha's mercy, moaning or whining when he gets too overwhelmed and more tears spill from his tired eyes, making katsuki stop licking and just leave playful kisses here and there.
195
when the intensity of his orgasm finally lets him come to his senses again, he opens his eyes, heavily and slowly, and it takes him a second to focus his gaze on the man holding him.

the king's red eyes are still trained on him, and there is a smirk on his handsome, smug face.
196
“you're so pretty like this,” the alpha mutters, carefully snaking his arm under the omega and pulling him onto his lap, not minding the sticky mess. he entertains himself kissing his cheeks and the tip of his nose repeatedly, scenting him with his chin and neck.
197
“kacchan's pretty too,” izuku mumbles, with a satisfied happy glint in his eyes as he softly brushes his fingers along the barbarian's jaw. “and kind, and loving, and generous,” he says, giving him such a lovestruck look that he has to resist the urge to shy away.
198
katsuki grunts, only to keep some of his dignity. 

“don't go around telling people that,” he chuckles, rubbing their noses together in a tender gesture. izuku giggles and allows his alpha to shower him in his affections, happily chirping and purring
199
growing up, the whole fated mate thing seemed a bit questionable to him, but he never dared to deny it. he grew up reluctant to his mother's promises that he would find someone who could complete him in such a way because, at that age, he didn't feel incomplete to begin with.
200
but as he grew older, this odd, uncomfortable feeling of something missing started plaguing him, like an itch he couldn't scratch or a need he couldn't figure out.
201
it was annoying, to say the least, but everyone said it was something intrinsic in the dragon people's nature that no one could escape.
202
he learned to live with it, as everyone else did. it became just a thought in the back of his mind that he couldn't quite ignore but it was also impossible to relieve.
203
fated mates came at the right moment, when you needed them the most and they needed you just as much. you could either be aware of this or not, but the elders advised you to always keep an eye open and an humble heart.
204
katsuki wouldn't say he waited, because his life as the king didn't let him much time to long for anyone. he kept himself busy, and time passed by without paying him any mind.
205
but now, with his arms full of omega and his heart bursting with this feeling of pure glee, katsuki finally understands why he's seen people die in the name of their mates.

he can't comprehend how he went without izuku for so long, and he doesn't think he could do it again.
206
and despite having experienced so much at a relatively young age, having been his nation's most important warrior when he was just a teenager and then becoming king when he was barely an adult, he feels like the most important part of his life is just getting started.
207
and luckily for them, so it's the night.

fantasy au ; eventual smut 🔞

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
209
katsuki received a lot of advice before his wedding day, especially from his parents.

his mother sat with him and lectured him about the most basic concepts, primarily regarding how to treat his omega right during their wedding night, how not to scare or pressure him,
210
telling him to be patient, and to make sure that whatever they did was an agreement between the two.

she said he could never be too sure, and that there was nothing more shameful than an alpha who couldn't control himself before an omega.
211
she also threatened to cut his dick with his own sword if she heard any complaints from his son-in-law the next morning.

the hag, as loving as always.
212
his dad, on the other side, asked him how he felt about the wedding, the mating, and the marriage. and the truth was that his father had always known how to coax the information out of katsuki without him even realizing it, so he doesn't resist being honest anymore.
213
one of the most important things they discussed was something katsuki promised him he'd bring up to his mate as soon as possible.

preferably when their minds were still clear.

“izuku,” the alpha softly calls.
214
“yes?” he sweetly replies, looking up at the blond as he smiles, still purring up a storm while being cozily nestled in his arms.

the barbarian pushes a strand of silky hair off his face. “we need to talk about a few things, my queen.”
215
the purring decreases until it becomes a steady background noise. izuku tries to sit up in his lap the best he can, watching him with curiosity and a tad bit of concern.

“yes, alpha?”
216
katsuki has to bite his lips and breathe through his nose as he internally screams because, damn. it's going to take him a while to get used to that title without feeling like his heart is bursting out of his chest.
217
he's not strong enough to resist biting one of the omega's chubby cheeks. izuku whines, but he giggles right after. katsuki licks the red spot as an apology and the purring gets loud again. “you're so distracting, you little menace.”
218
“me?” izuku pitifully asks, “but i'm not doing anything, kacchan.”

fuck. that nickname does things to him too.

“don't have to,” the alpha grumbles, now kissing his jaw, “you look too tempting just sitting there.”
219
izuku laughs, bubbly, and smelling happy. the sound of his laugh reaches deep inside the alpha, and it feels like gentle sunbeams in the winter.

the omega grins. “you're gonna be one of those alphas who can't keep their hands off of their omega?”
220
“yes,” he replies, finding that tender spot above his collarbone that makes the omega sigh. “you have a problem with that, your highness?”

“mmh, not at all, your majesty,” the omega hums, melting into his embrace. “i'd live in your chambers if that's what you want.”
221
oh yeah, katsuki likes that.

his lizard brain nods enthusiastically at the idea of izuku living naked and between the furs of their nest for the rest of their lives, always satiated because his alpha takes such good care of him,
222
provides so well, and keeps him happy and fed and full of his seed, belly forever swollen with his pups and…

wait.

katsuki growls as he uses every inch of his willpower to pull his head away from his wife's neck. izuku blinks at him, confused.
223
“is there something wrong?” he asks, tensing.

“nothing's wrong,” the alpha assures him. “but it would be very irresponsible of me not to discuss this with you before things go any further tonight.”

he's mostly reminding himself of that.
224
izuku blushes, eyes flickering down to his lap where he starts fidgeting with his fingers. “oh. o-okay. we can talk, kacchan.”

katsuki raises an eyebrow. “you can't be this shy when i just had my mouth in your cunt less than ten minutes ago.”
225
izuku chokes and his eyes shoot back to his blunt husband, red as a strawberry. “kacchan!” he squeaks. “you can't say those things!”

katsuki grins. “i'm the king, baby, i can say whatever the hell i want.”

and just because he just realized he likes teasing his
226
easily-scandalized wife, he lets his big hand slip from the omega's waist to his inner thigh, tantalizingly running the tip of his finger through his still-wet folds, not thrusting inside, just circling his entrance, slowly and unhurriedly.
227
cockily, he adds, “besides, you'll soon learn we have little decorum around here. and that dragons tend to have a rather high libido.”

izuku's hands fly to clench around the alpha's tattooed bicep, and his mouth hangs open in a silent whimper.
228
when he recovers some of his breath, he says, “didn't you want to talk about something important?” izuku breathes out, twitching when katsuki pets where he's warmer, helpless when new slick pours out of him, coating the alpha's hand.

mh, fertile little thing.
229
the way his body immediately responds to katsuki's touch has his dick twitching and his alpha roaring.

“can’t we do both?” he simply says, purposely bumping his clit as he retreats his hand back to his waist for the sake of actually having a conversation.
230
izuku slumps against him when katsuki's mean fingers stop teasing him. i can’t think straight if you do that, kacchan.”

katsuki pretends to ponder for a second. “i'll keep my hands to myself while we discuss this. how about that?” he offers, squeezing the omega's waist.
231
“so considerate, alpha.” katsuki thinks he can hear a hint of sarcasm in his tone. “we won't take long, hopefully?”

“eager, baby?” the alpha purrs. izuku flushes red again, making him cackle.
232
the alpha nuzzles him. “we have time, no need to rush anything. no one will enter this room unless i command them to. they're under strict orders to not disturb us until the sacred mating period is complete.”
233
he plants his feet on the ground and easily manhandles izuku to hold him by the waist against his hip, walking them over to the big bed in the center of the bedroom. izuku gasps and instinctively tucks his legs close to his body to avoid dragging them,
234
clinging to his husband the best he can. katsuki smiles to himself; the omega is too adorable.

carefully, he places the smaller man on the mattress. izuku blinks up at him. “mating… period?”

“you don't have those over there?” katsuki frowns.
235
izuku shakes his head. “i've never heard of them before. what are they?”

seriously? are these people civilized at all? he’s so glad izuku is out of there, fucking hell.
236
the alpha crosses his arms over his chest and tsks his tongue. “and they call /us/ savages,” he mutters, rolling his eyes before turning around to open the first drawer of the night table.

he pulls out a small round container, adorned with different shades of red-colored scales
237
and a golden lock with an odd-shaped orifice in the center. 

he hands it over to the omega. izuku looks between him and the container twice before grabbing it with cautious hands and holding it above his lap.
238
izuku stares at him with a slightly disconcerted expression on his face. he glances at the container again. “what… what exactly is this?”

“you said you wanted to be a knight,” katsuki repeats, “and you wish for many things before becoming a mother. was that true?”
239
the omega freezes, and his hands tighten around the little crate, the tendons on his wrists straining. katsuki finds the pale skin there too naked– they would look so good with a few bite marks.

Mhhh, later alpha. omega needs guidance now.
240
“then tell me, omega,” katsuki says, using his other hand to press it to the side of his neck, right above his scent gland, “are you sure you want to mate me tonight?”

izuku goes rigid, but it’s brief. he doesn't pull away, and that soothes some of the alpha's sudden nerves.
241
he promised izuku to grant every single one of his wishes.

if izuku decided this life was not for him, he would put him in his fastest dragon in the morning towards any place he told him to, give him enough food and water to last for as long as he needed, and kiss him goodbye.
242
izuku deserves the right to forge his destiny and walk down the path he chooses for himself. if katuski could provide him with at least that, he would do it. 

even if dragons rarely survive after losing their mates.
243
but his fears don't seem to be rooted in any truth, since izuku puts his hand on top of his and slightly turns his face to kiss his calloused palm.
244
as if reading his mind, he says, “don't be afraid, my king, i'm not going anywhere.” he releases a wave of calming omega pheromones, and katsuki feels all stress drain from his body. the alpha gapes at him and izuku offers him an apologetic smile. “you smelled worried.”
245
the alpha stares, not shocked but amazed by the spot-on intuition of someone who, despite having just met him that morning, seems to know him better than most.

fated mates share a single soul, the legends say.
246
katsuki must keep reminding himself that izuku has been living inside his heart for longer than it has been beating.

a love like the one he feels for his queen has to be as ancient as the gods themselves.
247
“i love you,” katsuki says, because that's why he fears. “i want you to be happy.”

“and that's why i will stay, alpha,” the omega tenderly replies. he rises to his feet, keeping the alpha's hand on his face, places the container on the bed, and stands on his tiptoes to place a
248
kiss on his husband's parted lips.

“my place is here, with you. i want to wear your bite on my neck more than anything. i love you, kacchan, being your mate is the thing i want the most right now.”
249
something warm blooms inside him, and now it's his turn to blink the surprise away beforebreaking into a fit of relieved chuckles. he grabs izuku's face, engulfing him, and without wanting to hold back any longer smashes their lips together in a hungry kiss.
250
it may be peculiar to see such a big man like himself melt like hot wax at the touch of a small omega, with a soul brighter than the sun, but katsuki found this weakness taking over his body and spreading further the more
251
the omega needily pressed his lips against his surprisingly pleasant, like a nice electricity thrumming through his veins. 

with a loud smack, the barbarian pulls back to whisper, “lay on the bed.”
252
izuku breathes through his nose and obediently takes a step back until the back of his legs touch the mattress. he sits, without breaking eye contact, and leans back on the bed, leaning on his forearms.
253
when katsuki moves forward, the omega's legs fall open, intuitively making space for the approaching alpha. 

katsuki hums, pleased, and reaches for the forgotten container beside the omega as he sinks one knee on the bed, in the space izuku's welcoming legs made for him.
254
“may i touch this, omega?” he asks. when izuku looks at him not knowing what he's supposed to reply, he adds, “i'll explain to you what it is for in a minute, but first, i need you to tell me i can touch it.”

“you can,” izuku says. “of course you can, kacchan.”
255
katsuki smirks. izuku is not so skittish anymore, –compared to the first moments they spent alone together, but rather inquisitive and open, watching his alpha's every move with anticipation instead of skepticism.
256
it's not easy to make a warrior take his guard down, yet izuku seems comfortable enough in the king's presence, splendidly naked and testing all of katsuki's self-restraint.

he must be doing well so far to be rewarded with this sight.
257
“this will determine whether you want to conceive a pup during the mating or not. tonight, or at any other moment. getting with child is, and will always be, your choice to make.”

izuku gasps, mouth falling open as understanding washes over his face. “oh gods, kacchan, is this-”
258
the king nods. “sacred paint, to cast a nullifying fertility spell,” he finishes the sentence, watching izuku's face flood with wonder.
259
“kacchan,” he gasps, then bites his lower lip excitedly when the alpha deposits the container into his hands. “you got this for me?” he asks, cradling it close to his chest like it's the greatest gift anyone has ever given him.
260
“i've only read about it in the ancient history books that warned about witches and sorcerers, dark magic and barbaric rites. the maids told me it was a lie but-”
261
katsuki growls an annoyed sound.

“those fucking maids of yours are gonna hear from me as soon as we're out of this bedroom,” he threatens, flashing his upper fangs in a snarl. he drops the act when izuku gives him a knowing look that inevitably softens him.
262
“every omega in here knows how to use it, it's part of the early teachings imparted to them when they are entering the age of presenting. they have to use it in their first heat to make sure they mastered the spell, it is the law.”
263
he can almost see izuku taking mental notes of everything he says, so he lets his mouth run a little more. “this one's a little different, though.”

the omega bites the bait, “why?”
264
“because the magic of our family is the strongest,” the alpha states, proudly raising his chin.

yeah, he was bragging, but it was true. his family has kept the throne for generations because no one has earned the right to take it from them.
265
their magic was the most powerful, and they vowed to use it for the good of their people.

they were fair rulers, good leaders and amazing warriors. katsuki hopes he can honour the throne the same way his parents did, with izuku by his side as his beoved queen.
266
the king smiles. “you're family now, bound to the dragon lineage forever from this day. i will personally teach you everything you need to know about our magic when the time comes. i'm sure youll catch up to me in no time.”
267
green eyes shimmer, and a couple of interested happy chirps betray the omega. 

katsuki feels inexplicably proud seeing his omega so eager to know more about nearly everything he mentions.
268
oh, he has to see the royal library and share a meal with the elders, he's going to be so excited.

he cannot wait to show him everything about their home and see that pretty face light up at every new piece of knowledge.
269
izuku is so smart, so capable. he can easily see how his father couldn't resist giving him a chance to be more, despite how conservative of traditional gender roles izuku's kingdom is known to be.
270
“how does it work?” izuku questions, putting aside his embarrassment and barely containing the excited curiosity that katsuki is learning is one of izuku's most endearing traits.
271
“is it a figure? or perhaps a scripture. i read about some cultures using a pattern of dots and lines, but there must be so many other methods!”

“runes,” katsuki smiles, touched by his omega's contagious enthusiasm. “our magic uses them a lot.”
272
“oh, kacchan, that makes so much sense!” he gasps, adorably covering his mouth. “dragons are summoned through runes too, right?” 

katsuki arches his brows, intrigued. “something like that- but not quite correct.” izuku's excitement falls and morphs into a frown.
273
his alpha howls, terribly anguished at the omega looking evern remotely sad.

he hurries to say, “but it's close enough. how did you know that, anyway? i thought we kept our secrets better around here. was that in one of your books?”
274
“oh, no, that's-” he scratches the back of his neck, offering his husband a coy smile. “dad told me a lot of stories of his young years, before he became a king. most of the things i know come from dad's traveling tales and well… i've always loved learning about other places.”
275
the king all might is a wise man.

katsuki had fought alongside him in the war, unexpectedly and in a moment of crisis for everyone. their kingdoms became allies when the enemy became too strong, and only together did they defeat the evil threatening their lives as they knew it.
276
the barbarian –not yet a king himself by then, guarded the king's back against enemy attacks in the middle of the battlefield, tended to his wounds before going to sleep every night, and cried his fears out to him when he thought they may not come alive out of that moody field.
277
he wonders if their shared days in the war have anything to do with the king immediately accepting his request to have izuku's hand in marriage shortly after he took the throne.

looking back, he also suspects that izuku and he didn't meet for the first time that morning.
278
everything in due time.

katsuki scoffs, fondly, and leans down, closer to his omega. “did i marry a nerd?”

izuku pouts, looking up at him through his lashes in a dirty trick. “maybe.”
279
the alpha smirks. he fishes among all his necklaces and colorful beads for a leather string with a single dragon fang attached and takes it off. izuku watches with quiet curiosity as he grabs the necklace and holds it in front of them.
280
“come here,” he instructs. izuku scoots closer to him on the bed, eyes on the necklace. 

katsuki then puts the leather string around his neck and makes sure the fang hangs neatly at the front, right between Izuku's little omegan breasts.
281
his nipples harden to the cool touch, and katsuki can't help brushing one of them with his thumb, marveling at the way izuku's skin fills with goosebumps.

“the only way to open the lock is using the fang in the collar. you must carry it with you at all times.”
282
izuku looks down, and takes the fang in between his fingers, feeling it roll.

katsuki doesn't have to say anything for him to bring the container up and slowly fit the fang inside the lock, twisting and turning until something clicks and the lid falls onto the bed.
283
there is a thick, dark liquid pooling inside. litmus, like oil under the light. 

the alpha dips two fingers inside, and they come out dripping. 

“its gonna feel warm,” he mutters, and izuku just nods, wide-eyed.
284
the alpha sets his clean hand on izuku's plush upper thigh and slowly drags it up to his lower belly, fingers pressing on the soft skin, searching with gentle thumps and touches.

his furrowed brow rapidly smooths when he finds what he's looking for.
285
he presses the length of his hand flat on the omega's pudgy tummy, and it makes his mate faintly yelp.

“here's your womb,” the alpha rumbles, “the runes need to be written right above it.”
286
“kacchan.” izuku is giving him an unclear look, his eyes are a bit misty and he is biting his tongue. his scent, however, is sweeter. “don't you… want pups?”
287
katsuki hums. he pets over the omega's navel and dives down to leave an open-mouthed kiss, feeling izuku's abdominal muscles twitch under his lips.
288
“someday, if you're ready, i'd love to have little brats running around. maybe a boy, with your kind personality and your magnificent emerald eyes,” he says, looking up at izuku with his mouth still attached to his belly, speaking in the swift moment between kisses and breaths.
289
his kisses go lower, under izuku's belly button, above his fuzzy mound. “or perhaps a girl. resilient like her mother and with her beautiful, charming freckles and fluffy head.”

izuku makes a breathy, needy sound, and katsuki bites down hard enough to leave a mark.
290
the omega gasps, giddy and drunk on his alpha’s attention.  

“or with ash-blond hair and a noble spirit, like their father,” he manages to say, finding the alpha's head and combing through his hair, lovingly staring at the man worshiping his body so arduously.
291
“any pup you give me, omega, would be a blessing,” he replies. with his paint-wet fingers, he writes the first rune right under izuku's belly button. 

the omega takes a deep breath, locking eyes with the alpha. katsuki drags his tongue over his teeth as he grins.
292
“but at least for a while, I want you to be all for myself,” he purrs, with a smug smirk on his lips and a predatory look in his eyes, devouring the omega with them.

izuku’s scent explodes in sweet notes and katauki feels his sanity dissapear.
293
that was a great talk. he really enjoys sharing conversations with his omega.

but he's had enough of them for the night.

right now, katsuki needs to claim izuku and knot him as soon as he can.
294
alright, link to the top!!

fantasy au ; eventual smut 🔞

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
295
the omega flinches and breathes through his nose as katsuki keeps painting words in a language the queen doesn't yet understand. the air gets rich with both of their feverish scents, and it makes katsuki rumble.
296
“you have me, my king,” izuku sighs, fingers still lost among golden strands of hair, “what are you gonna do with me?”

he gives his husband a sultry look, slowly blinking his beautiful forest eyes. the alpha growls, and the last bits of his patience escape through his teeth.
297
“Oh, sweet little thing,” he says, huffing a dark laugh. a familiar heat builds inside him, and he blows hot puffs of smoke out of his nose. he hunches backward, arching his back to allow the scales to pop off
298
one by one on his back and chest, along with sharp claws on his fingers and curved horns on his head. his fangs become larger, poking a little out of his lower lip. he licks them before saying, “i am going to devour you.”
299
izuku's eyes widen, big and full of bewilderment, but his scent never sours with fear. he lays down, heavily panting, observing his husband stir and huff as he shifts into his dragon form like it's the most exhilarating thing he's ever seen.
300
his face and body remain mostly human, but his dragon nature is clear all over his being. the alpha gleams as his beautiful scales catch the light of the fire bathing the room in its warm glow, his pants tear into shreds as his powerful thighs grow with the rest of him,
301
leaving him naked before his omega in all of his shape-shifter glory.

he looms over the breathless omega, eclipsing him like the moon would the sun.

“kacchan,” the omega whispers, watching him with glinting eyes, lacking the words to describe his feelings.
302
“most people freak the fuck out the first time they see us shift,” the dragon purrs, voice deep and husky, erotic in its bestial hues. he leans down, caging the omega below him, “but you don't seem scared at all.”
303
“you're beautiful,” izuku breathes, eyes sparkly and lost in the magnificent beast that is his husband. “you're breathtaking- you're…” he reaches for him, stroking the scales along his shoulder and neck, then carefully feeling the sharp tip of
304
his fangs with his finger pads and caressing his lips before setting his hand on his cheek and finding his ruby eyes.

“the king of dragons. and all /mine/.”
305
the alpha's chest rumbles with a possessive sound. he preens under his wife's praise and worshiping gaze, scales standing up proud in response.
306
“beautiful, huh?” he huffs, nuzzling the omega's neck, teasing the skin with his enlarged fangs, “no one's ever called me that before. terrifying, arrogant, barbaric, yes, but never something so pleasant.”
307
“i bet you're even more beautiful in your full dragon form,” izuku says. “how is it like?”

“big,” katsuki replies, a smug smirk on his lips. “and red, the same shade as my eyes.”

“when can i see you?”

“whenever you want. your wishes are my commands, my queen.”
308
izuku bites his lips, contemplative. he scrutinizes him, drinking in every new detail of him. his smart eyes travel all over the king's broad body, and so do his hands.
309
katsuki has to resist the need to shiver and bend under his omega's curious hands, but his knees buckle when izuku scratches between the scales on his lower back.
310
when he does this, his cock slides down izuku's abdomen, right on the imprinted runes on his belly. the alpha bites down a moan, but it's too late.

izuku has frozen, and his eyes are as big as plates.

they look at each other, barely blinking, holding their breaths.
311
katsuki doesn't want to say he was afraid of this moment, but it's useless to lie. when he realized his fiance was so incredibly small compared to him, his mind immediately went over the possibility of this being a problem.
312
when dragonkin marry outside of their kind, it's not uncommon for their partners to have some issues adapting to their… sizes.

izuku is so tiny, and most likely a virgin. katsuki has no idea how he will react upon realizing…
313
a loud purr interrupts his train of thought, and he comes back to himself to find that his omega's eyes have become hazy and his skin has blossomed a vibrant red. his scent glands shine as oils drip from them, letting katsuki know the omega is /very/ intrested.
314
izuku licks his lips. “it depends then,” he says, hypnotized gaze fixed on his husband.

“what… does?”

“when will i want to see your dragon,” he mumbles. his fingers find the alpha's necklaces before sliding down his abs and navel, hesitating only for a moment before spreading
315
his hand over his navel.

“how big are you?”

katsukis eyebrows raise to his hairline, and he has to bite his tongue.

“i'm very big,” he replies, repeating his move from earlier so izuku touches the base of his fat knot.
316
the omega purrs with his whole body, practically vibrating under him. “yeah?”

“the biggest one,” he says, returning the purrs.

“in that case…” shakily, the omega braves enough to go lower and get a hold of his erection.
317
he sucks in a breath when he realizes his fingers don't touch around it. “i think i'm going to wait.”

“that's fine with me, love,” katsuki says in a velvety voice, “we've got much better things to do right now.”
318
“kacchan,” he gasps, finally looking down at the enormous cock in his hand. he gives an experimental squeeze and katsuki buckles forward, a whine contained in his throat. “that won't… how-”

“we can stop-”
319
“no!” izuku whines, “i want your knot!”

katsuki stops and blinks at him. then, he cackles. “well, damn. aren't you full of surprises?”

izuku flushes an even darker shade of red. he looks down, cheeks puffed and lips tight.

“it's just… i've never…”
320
the alpha gently grabs him by the chin and brings his gaze up.

“i know, baby,” he says, caressing him with his thumb, “we’ll be careful. you’re made for me and i’m made for you, remember?”

the omega’s eyes glint, and he nods.
321
“have you ever… been with someone before?” izuku mutters, shyly. katsuki must make a funny face because izuku's expression turns awkward and flustered. “never mind, that was a stupid question. you're the king, of course, you-”
322
“i ain't got time for that. thinking about spending my ruts with some stranger makes my skin crawl just thinking about it, so i've taken care of them myself. besides…” the alpha's long fingers find the omega's opening, and izuku gasps.
323
“i always knew i was going to have an arranged marriage , most likely with a foreigner. i know traditions outside my land, the fixation people have with purity and shit. i figured… it wasn't fair to my bride if i could be fooling around when he or she wasn't allowed to do so.”
324
“you waited? all this time?” the omega whispers, looking at him with big, awed eyes.

katsuki grunts, feeling his face getting warmer. “yeah. so did you, it's no big deal.”
325
the alpha feels a gush of slick permeate his fingers, and he takes the opportunity to plunge the tip of his finger inside. izuku sighs and his head lolls to the side.
326
“it's a big deal to me,” he says, watching his husband through the corner of his eye, and smiling. “it makes me happy.”

katsuki genuinely doesn't know what to say; izuku looks like an angel and he's saying so many things that make his heart beat faster and his face feel hot
327
from his neck to his horns. his finger is throughoutly exploring his wife's insides for the first time and somehow the omega still managed to make /him/ flustered.
328
“stay still, i’m going to prep you,” he mutters, concentrating on working his hand because looking at izuku seems like too much right now.

the omega giggles, then muffles a whimper with the back of his hand when katsuki tries to push his finger past the second knuckle.
329
“if you prep me, it won't hurt?” asks izuku as katsuki continues moving his fingers.

the omega stares at him with slightly furrowed brows in barely concealed nervousness. his tights squeeze the arm intruding between, probably trying to close them on reflex.
330
katsuki grabs one of them and gently folds it towards his torso, leaving a kiss on izuku's flexed knee.

“open your legs for me, baby — that's it. i promise i won't let it hurt,” the alpha replies. “scream, bite me or do whatever you need to and i will stop what i'm doing."
331
slowly, a small smirk pulls at the corners of his wife's mouth, making his cheeks look even chubbier.

“how did i end up with the perfect alpha?” izuku sighs, stars dancing in his eyes.

if izuku keeps looking at him like that, he will pop his knot embarrassingly soon.
332
“had to measure up to my omega,” he grumbles, trying to look unaffected and miserably failing.

god, this omega is going to make his ego blow up if he keeps running his mouth like that.

he better shut him up before it happens.
333
he starts twirling his finger around, feeling the soft and warm texture of the soft skin. he keeps an eye on izuku to ensure he's not uncomfortable and keeps going when he confirms that his brows are pinched together in pleasure and not pain.
334
when the omega opens up slightly more to him, he rubs his middle finger in izuku's slick to add it next to the first one, starting with the slow pumping motions until it's completely inside.

when the omega's thighs start shaking, he kisses one of them. “how does it feel?”
335
“you're making it so good,” izuku says, “keep doing that.”

katsuki grins. “bossy, aren't we?”

a third finger joins, and izuku whimpers. the alpha thrusts his fingers together and searches for that little spot his omega friends told him to look for.
336
spongy and wrinkly, nestled close to his entrance but well hidden… they said he'd know he had found it because izuku would-

“ah!” the omega screams, back arching off the bed, slick gushing out. “what-”

heh. there it is.
337
the alpha presses on the squishy spot inside the omega and then rubs it with two fingers. “that's your sweet spot, baby.”

izuku moans, moving his hips in tandem with the alpha's blessed hand, throwing one arm over his face to cover his ravished appearance.
338
the alpha growls and uses his free hand to snatch both of Izuku's wrists and hold them above his head, gently but firmly restraining them.

“be a good omega and let me see the pleasure i give you,” he orders.

izuku nods, slowly, looking beautifully dazed. “i'm sorry, alpha.”
339
katsuki nuzzles his neck, kissing and sucking at his scent gland, hand never stopping, only picking up on its rhythm. “you're good, so good for me already. so beautiful, i want to look at you forever.”
340
his wife moans louder when he pulls one finger out and starts scissoring him with the two left inside. izuku seems to be enjoying himself, judging by how he squirms and the sweet sounds he's making.
341
“you're opening so well for me, omega. do you think you could take a bit more of a stretch?”

“i can,” he pants, raising his head, “what are you going to do?”

katsuki promised no pain; he needs to make sure izuku loosens as much as he can before his dick goes anywhere near him.
342
even if omega bodies are made for this, the alpha wouldn't be able to live knowing he hurt his omega on their first time because he was too horny to prep him properly. he's not a slave to his instincts, he can wait, damn it.
343
he kept his hands human, not wanting to overwhelm the omega and knowing it would be easier for him to start little by little. it takes him a second to transform his hand, and izuku immediately notices because he yelps and jerks as soon as katsuki tries to coerce
344
his fingers back in, tightening around him all over again.

as his fingers doubled in width and length, he starts with a single one, just as he did earlier, circling his whole with the pad until it slips inside on its own when izuku's body is ready to take it.
345
izuku hides his face in the crook of his neck, and bites down on his shoulder with his cute little omega fangs. it would surely leave a mark –gods, he hopes it does.

“they're warm,” the omega whispers close to his ear. “and… wet?”
346
“our scales lubricate naturally when they come in contact with our mate's reproductive organs. something similar to the oil in our scent galnds. you know, to make everything a lot easier.”

“seriously?”
347
“yeah,” katsuki affirms. “you'll see.” and apparently, izuku is too distracted by the fingers inside his pussy to provide any further comment, because he only grunts and nibbles at the alpha's collarbones in response.
348
the barbarian kisses his hair and tells him what a marvelous job his doing at taking his fingers as he inserts another one, slowly penetrating him deeper and faster until the omega is moaning again, trying to fuck himself on his fingers as he desperately cries and mewls.
349
the third and fourth fingers enter easily after that, but the omega must still feel them because he gasps, his thighs tensing and pussy clenching.

“shh, you're okay. too much?”
350
“no, no,” izuku replies, katsuki can feel him wrinkling his freckled button nose on his neck. “i feel so full,” he sighs, and drops his forehead with a content sound, “it's like my body's been waiting for this for the longest time.”
351
the king frowns. “damn maids,” he grunts under his breath. izuku chuckles, and katsuki patiently waits for him to adjust before he starts thrusting again, taking his sweet time, distracting him with soft kisses and praises.
352
it doesnt take long before izuku is completely nice and loose, breathless and pliant in his hands.

katsuki keeps missing his clit on purpose, and izuku looks more desperate every time he brushes past it.

“kacchan, touch me.”
353
“i am touching you,” he says, mean and teasing, “is that not enough?”

“no, i mean, argh- the other place!”

katsuki presses on his sweet stop and izuku chokes a moan. “here?”

“no,” izuku squirms, “my c-clit!”
354
“ah, so you do know what it's called. i was wondering how much those bastards kept from you but you're not so bad, just a little shy.” he gives him a side-smirk, showing his fangs. “and no, baby, i'm not going to touch your clit right now.”
355
“what?” izuku cries, pitifully looking at him through wet lashes, “why not?”

it seems like his omega is already getting spoiled, huh?
356
the alpha presses his lips to the shell of his ear and curls his fingers inside his pussy. izuku whines, and katsuki greedily drinks in the sound.

“because next time you come, it will be on my cock."
357
he rolls his hip, rubbing his erection on izuku's thigh. the omega chirps from the bottom of his chest, eyes widening and scent turning excited. the alpha corresponds with a rumble, pleasedly getting drunk in the scent and kissing up and down his wife's neck and shoulders.
358
izuku looks down, but frowns when he realizes he can't get a good glance at what his husband is doing.

“i want to touch it,” the omega determinedly says, surprising his husband.

“my cock?”
359
izuku nods, timid but showing no signs of backing down. “kacchan's been making me feel so good all this time, i want to try too..."

“of course you do,” the alpha huffs, nibbling his freckled shoulder.
360
“but you don't have to do anything for me. pleasing you it's been my utter delight, omega.”

izuku, the sneaky little thing, slides his hand between their hips and wraps it around the alpha's cock again. but this time, he doesn't let go when he twitches.
361
“i want to know what's going to be inside me,” he says. his eyes go where his hand is and they widen at the sight. katsuki can't help but feel smug at the stunned and hungry face that his omega is making right now. “oh my gods… you're going to split me open.”
362
katsuki hums, cheekily. “traditionally, we mate in our dragon form. but i can always shift back and-”

izuku snaps his omega teeth at him. “don't you dare. i want this one.”

oh, he fucking loves him.

“yeah? you're into dragon cock, baby?”
363
izuku doesn't grace him with a response, he's too busy wiggling so he can be all handsy with his dick to pay his teasing any mind.

“tell me what you like,” the omega asks, licking his lips and looking at him with a heated face, squirming to get closer to his dick.
364
his face brightens when he realizes his dick is also covered in scales, although they're smaller and infinitely more sensible than the ones on the other parts of his body.

izuku strokes them with his thumb, curious and careful, amazed at their flexibility and softness.
365
the alpha smirks. “move your hand up and down — mmh, yes, exactly like that. and use your thumb to stroke the tip.”

“why the tip?”

“it's sensitive, like your clit.”
366
his brows knit together in concentration and he does as told, stroking the length slowly at first, like savoring the skin-to-skin contact and marveling at how the barbarian hissed and trembled when he caressed the pink, shiny head.
367
“am i doing it properly, alpha?” the omega innocently asks, batting his eyelashes at him.

“yes, baby, you're perfect,” the alpha pants, shallowly bucking his hips to fuck into izuku's lovely fist. “feels so damn good.”
368
izuku purrs and smiles, and decides to be bold and reach for his shaft with his free hand. he feels his pubes and then curiously fondles his balls, tracing them softly with his index finger before moving on to the next interesting thing: his knot.
369
the truth is, katsuki feels like he's about to pop. it's taking all of his willpower not to come. someone else's hand on his dick feels so different from his own, so much better; it's like he can just turn off his brain and give in to the pleasure,
370
not worrying about the hollow pain that comes after furiously masturbating during his ruts nor the loneliness that strikes him when there is no one by his side when it's over.
371
he's got his omega now. this beautiful, kind, lovely little thing whose eyes shine like precious jewels and whose smile makes everything else seem mundane.

the same omega who's currently squeezing his knot and making the air leave his lungs.
372
the alpha snarls and grabs the omega by the wrists again, forcing his hands away from his cock and trapping him under his broad body. izuku's eyes close, and he bares his throat for him in a submissive display, a low whine leaving his lips.
373
katsuki is quick to comfort him, lapping at his cheeks and chin. “i'm sorry, omega, but if i'm going to pop my knot it's going to be inside you.”

“do it then,” he replies, then adds in a much softer tone, “i'm ready, kacchan.”
374
and he looks so gorgeous, luscious curls sprawled on the pillows and a blush spreading on his freckled skin, smelling so exquisite, with his neck still bared to him and an earnest smile on his lips, a blissful look in those eyes katsuki was so lost in.
375
something inside him snaps. everything about izuku is so alluring to him, so breathtaking, and just so /omega/ right now. it's like the mere sight of him pulls at the most primal parts of the alpha whitin him, setting his instincts on fire, and demanding him to claim, bite, knot.
376
katsuki gives in.

he bares his fangs with a vicious growl, a sound that would probably be bone-chilling to anyone else but makes his omega enthusiastically chirp, opening his legs even wider for him to fit between them.
377
he scents izuku, making sure he’s drenched in his spicy scent as he plants his knees on the bed and sets his arms on each side of the omega’s head.

immediately, izuku wraps his arms around him, purring and trying to pull him even closer.
378
“you smell so amazing, kacchan,” the omega says between purrs, “cinnamon has always been my favorite.”

he nuzzles the crook of his husband's neck and licks a fat stripe from his collarbone to his ear, nibbling at his pierced earlobe and making the alpha choke with his spit.
379
he’s been doing most of the kissing and caressing tonight, and as much as he's thrilled izuku may be high enough on endorphins not to be shy anymore, he's going to blow his load way too soon at this rate. so he takes his heavy cock and lines it up with the omega's entrance.
380
“omega,” the alpha says, resting his forearm above izuku's head on the mattress so he can pet his hair. izuku feels the head of his dick pressing at his hole and his scent spikes with soft notes of arousal and anticipation.
381
he sucks in a breath, looking for his alpha's eyes and tightening his grip around his shoulders. “i love you,” katsuki says, honest and vulnerable.
382
the omega stares at him as a mix of emotions flashes through his face until he finally settles in a soft little smile, shoulders relaxing and scent becoming nothing but happy.

he brings their foreheads together and whispers, “i love you too, my king.”
383
the alpha kisses him, slow, hungry, and possessively, and he pushes inside.

there is no resistance, just soft walls opening up for him as he moves. izuku is so wet, it's like no other thing he's ever felt before.
384
between izuku's thick slick and the oils lubricating the scales on his dick, the first thrust is smooth as silk.

izuku throws his head back, and his nails scrape the alpha's strong back, leaving red lines in their wake.
385
his knobby fingers dig into the meat of his shoulders with a bruising force, but katsuki barely notices anything that's not the delicious tightness around his dick and the intoxicating scent of his omega.

when he bottoms out, hips flushed together, he finally breathes again.
386
izuku makes a little needy sound, urging him to rub their scent glands together, earning purrs and chirps in return.

he wants to give the omega time to get used to him, so he clenches his jaw and distracts himself by kissing and nibbling the omega's plump lips.
387
izuku is eager to kiss back, sighing when their tongues meet and their spit combines.

katsuki always thought kissing was gross. he gagged when his parents did it, and mentally groaned when he got older and his friends began to find mates. any sort of affection display
388
made him deeply uncomfortable, and thinking about being so close to another living being annoyed him to no end.

but now, covered in izuku's juices and their sweat, enveloped in his scent, and having all of their limbs tangled together, he can't get enough.
389
it's everything he never knew he wanted and more. it feels right, like his body has been waiting for this moment.

“alpha,” izuku murmurs on his lips, pupils blown wide. “move.”

“wrap your legs around me,” he hisses. izuku does, squeezing him with every move and making him moan.

every part of them was touching somehow, their legs, their hands, their bellies. it drives him crazy with possession and desire.

he dragged his hips back, inch by inch until only the tip of his cock remained inside, and then slammed back inside in a single thrust.
391
the omega screams, his eyes roll back and he clenches down /hard/. katsuki growls and buries his nose in the side of izuku's neck as he begins sinking into the omega, searing pleasure instantly sparkling through him as he sets a frantic pace.

fantasy au ; eventual smut 🔞

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
393
“alpha,” izuku wails, clinging onto him as the barbarian thrusts inside deeper and deeper.

katsuki takes a heavy breath, struggling to push the words out. “omega, how- 𝘰𝘩, 𝘧𝘶𝘤𝘬. how do you feel?”
394
“i can feel you in my throat,” he pants. “you are so big, kacchan, i can barely breathe.”

“that's exactly how i want you,” the alpha growls. “full of me.”
395
he desperately tries to get closer, to thrust as far as he can without losing himself in the pleasure because he wants to remember every single second of this moment.
396
he wants to bury himself in his omega, to obliterate all the things that keep them as two separate people, and to become one with his fated mate as the gods intended them to do.
397
the alpha plants himself in the bed and covers the omega with his whole body. he needs to make sure not an inch of izuku is away from him or he'll die.

he pulls back and then pushes in, again and again and again.

“gods, izuku,” he groans, “you're squeezing the life out of me.”
398
“i can't help it,” he says, voice breathy and ragged. katsuki watches his curls bounce with the force of his moves and decides he wants to make them go faster. “it's involuntary, you're just so– oh!”
399
he speeds up, not really knowing what he's chasing. he just needs more of everything. of his omega, of his sounds and his scent, of the pleasure coiling in his belly and the wetness around his dick.
400
his hips stutter with inexperience, and his mind threatens to go blank, but he doesn't stop.

“i’m so what, my queen?”

“so wonderful,” he cries, indiscriminately moving his hips with katsuki’s, tightening his legs around his waist and using him as support.
401
“i never thought it could be like this. it feels like a heat but it doesn't hurt and-”

“your heats will never hurt again,” the alpha swears. “for as long as i live, omega, the only pain you'll ever feel will be my teeth on your neck.”
402
“you promise?” izuku suddenly whines, grabbing him by the nape of his neck and bringing their faces close enough to feel their broken, fastened breaths mingle.

his green eyes tear a hole in his soul and burn him to a brisk, filled with an intensity that has his crooning.
403
katsuki almost howls. “i swear on my life, izuku. your heats– ”

“no, not that,” the omega hisses exasperatedly, he gets even closer, nose to nose. “promise you'll bite me, mate me.”
404
katsuki stops, making izuku growl and then give him a stressed look.

so his little omega is still worried his alpha might not want him. might be second-guessing the promise he made before him to the gods, their people and their families.
405
as if he wasn't a man of his word, a king worthy of trust and respect.

what kind of man would be so stupid as to let go of the other half of his soul when he just found it?
406
what kind of alpha would deny his omega whatever they ask for in their nest, on their wedding night, while they mate for the first time?

izuku could ask him to kill a man right now and he'll do it, in the blink of an eye.
407
but it turns out that izuku’s omega, deep in his most primal instincts as he is right now, is still afraid of his alpha rejecting him.

and he won't allow that to go on for another second.
408
katsuki flips them over the bed, and gives izuku a firm slap in the ass when he manhandles him where he wants him. izuku yelps, and looks over his shoulder with wild eyes.

“present, omega."

the command is low and intimidating, coming out from his chest in a husky rumble.
409
the omega’s eyes expand into black pupils and he moans, scrambling on the bed to get himself in all fours, then dropping his head down over his forearms.
410
he arches his back and sticks his ass out in the air, opening his legs as much as he can without losing his balance into a traditional presenting position, showing his submission to his alpha and accepting his request to breed.
411
commands can help omegas to get into the right headspace when they're ansty or restless, but they also require a tremendous amount of trust to work efficiently, to be soothing instead of distressing and make omegas relax enough to slip into omega subspace.
412
katsuki needs izuku to stop thinking and rely on him completely. his omega has probably spent his whole life worrying and fending for himself before arriving to katsuki’s kingdom.
413
the alpha lets out a strangled moan at the lewd sight of izuku's red, puffy hole clenching around nothing, gushing out slick that runs through the back of his legs and onto the bed.
414
the barbarian palms his ass with both hands, obscenely pulling his asscheeks apart to have a better view of his needy pussy, and his cock twitches in attention, still painfully hard and drooling, begging him to get back inside.
415
“you need to trust your alpha,” he growls, no bite in his words, just a warning tone. he smooths his hand down the small of izuku’s sculpted back, satisfied when it arches even further under his touch, pushing his plush ass higher as his face gets shoved into the covers.
416
“i know that smart brain of yours is used to work nonstop, but that ain't necessary anymore. your alpha will take care of everything.”

izuku purrs, mindlessly nodding and babbling a high-pitched sound, wiggling his butt impatiently.

“yes, alpha.”

“yes what?”
417
“i won’t think anymore,” he sputters, voice wobbling. his eyes and his lips are glossy and it's such an arousing sight. katsuki’s dick throbs again.
418
“not when my cock is inside you,” katsuki says, running his hand over his ass, pressing his thumbs to his pussylips and spreading him open.

his cunt flutters, and the alpha has to bite the inside of his cheek to keep himself from putting his tongue inside him.
419
“or ever again if you don’t want to, don’t give a fuck.”

izuku moans, half-muffled into the bed but needy enough to get katsuki going.
420
he arches a brow. “yeah? you like that?” he asks with a wolfish grin on his lips. the head of his swollen cock rubs at the omega’s entrance, spreading pre cum between his folds. “you want to be the dragon’s little toy?”
421
the omega nods, whining, and his legs shake as they struggle to keep him presenting. but izuku is stubborn, and he strives to maintain his posture.

there is something so bewitching about seeing such a strong omega offer himself like a treat in a silver plate just for his alpha.
422
for katsuki.

it nearly brings the barbarian to his knees.

the alpha’s mouth dives between izuku’s shoulder blades, kissing and mouthing at the skin, following his spine with his barbed tongue and crooning when izuku sighs and sags.
423
“you can be my pretty jewel, just made to look beautiful and take everyone's breath away,” katsuki mutters.

he can picture it, clear as day.
424
izuku dressed in the finest gowns, proudly showing the bite mark on his neck, wearing whatever jewelry he picks from katsuki's remarkable hoard and still looking more stunning than any of them.
425
bracelets, collars, anklets, rings, neither being jaw-dropping enough as the omega carrying them with such elegance and grace.
426
a crown on top of his luscious curls, either the one passed down from his mother or a whole new one if he desires it, sitting on his lap in the throne room and helping him with the kingdom’s duties or just sweetly purring to keep katsuki from losing his temper.
427
people from other kingdoms coming into the big fancy room only to be left speechless by the most magnificent omega in the world, his dear wife, his gorgeous queen.

his mate.
428
izuku glances at him over his freckled shoulder, face made a beautiful mess of tears and sweat, and he gives him the sultriest look katsuki has ever seen.

“you said you'll take care of me, give me anything i wanted.”
429
he pushes back on katsuki's cock until his ass is pressed to his thighs and dick, smearing his slick and aroused scent over him like he was marking his territory.
430
“how can i take care of you, my dearest,” katsuki asks, running his hands along izuku’s hips. he already knows, but hearing his omega ask for what he wants is like music to his ears.

izuku hooks one of his feet in the back of katsuki’s thighs and pulls.
431
the alpha yelps an aborted sound when izuku moves from under him as he loses balance, and right before he hits the mattress, izuku rolls on the bed and traps him between his thighs, making him land in his back as the omega ends up straddling him.
432
the alpha blinks in shock at the omega sitting on his lap and looking down on him with a mischievous glint in his eyes.

“you said i had to pin you down earlier,” izuku says.

he said that didn’t he?
433
an amused grin slowly stretches katsuki’s lips.

“you just caught this nation’s greatest warrior off guard,” he remarks. “not even my greatest soldiers have managed to do that.”

“they probably don’t know what it's like feeling empty after having your cock,” the omega replies.
434
the barbarian’s eyebrows shoot up.

“where’s that dirty mouth coming from?” he teases, bringing his hands to rest on the omegas thighs and rubbing affectionate circles with his thumbs.

“you’re rubbing on me,” he shrugs.
435
katsuki barks a laugh that gets caught up in his throat when izuku wiggles his hips and his cock feels wet and warm again.

izuku tightens his thighs grip. “inside. /now/,” he demands. “then bite.”
436
“then bite,” katsuki repeats, getting a tight hold of the omega’s hips to lift him up enough to angle himself.

katsuki doesn’t even needs his hand because his cock stands proudly, rock hard, and it slips right in as he matches his hips with izuku’s entrance.
437
they moan at the feeling of being joined again.

izuku bites his lips and takes a deep breath. he presses his hands on katsuki’s chest and closes his eyes, expelling a puff of air through his nose.

“you alright, sweets?” the alpha softly asks.
438
“mmhh.” izuku nods, smiling. “just need a minute.”

katsuki smiles back at him like only an utterly enamored alpha would and waits, and in the meantime, he takes the time to observe his omega in all his sex-haze glory.
439
his freckles —gods, how much he loves his freckles— are all highlighted by the blush of his golden skin and he's all sweaty with exertion, almost glowing under the lamps’ orange-ish light. his hair sticks to his forehead and curls around his ears and eyes,
440
his tits are the normal size for a male omega. pink puffy nipples on top of little mounds of fat, the dainty nubs are hard and swollen with arousal; they lean onto the small side, probably because izuku has built a lot of muscle.
441
katsuki thinks they're perfect, he wants to suck on them as soon as he has the chance.

the barbarian’s attentive eyes trail lower towards the omega’s pudgy tummy, not expecting to find a slight bump under his belly button.
442
katsuki narrows his eyes and nearly chokes when he realizes what it is.

“kacchan?” the omega he mutters, opening his eyes at his alpha’s sudden pheromone release and frowning at his stunned face.
443
katsuki doesn't reply. instead, he puts his big hand over izuku’s lower belly and presses down.

katauki groans when he feels the press of his own hand on his dick despite being still buried deep inside izuku and accidentally buckles his hips up.
444
a high-pitched moan is pushed out of izuku in consequence, and the omega has to look down to see what has his alpha so riled up.

his eyes widen when he sees his distended belly, and he has to bite back a moan.

“is— is that…”
445
“yeah,” the alpha replies, eyes glued to his belly. he traces down the outline of his cock and the omega shivers under his touch. “is this how you'd look pregnant?”
446
izuku puts his hand over the alpha’s and giggles. “i think my tummy would grow more. you're a big guy so your pups are probably gonna take a toll on me.”

“those brats,” katsuki mutters, more dreamy than annoyed, biting his lip as he keeps staring adoringly at his mate’s belly.
447
his hand slides down to where they're connected, and he marvels at how izuku’s pussy stretches around his cock.

his thumb opens up his puffy lips and finds his clit, and he brushes over it with a light touch.

the omega clenches around him, and he can /see/ his cock twitch,
448
izuku starts moving his hips, looking for more friction, so katsuki starts gently rubbing his clit in slow circles, making the omega whimper and rock above him.
449
finally, the alpha senses the omega completely relax. izuku releases a deliciously sweet scent, and katsuki feels his little toes curl where they rest over his legs.

the alpha hums. he places his free hand over izuku’s waist and squeezes. “i’m gonna move, baby.”
450
izuku frantically nods. “please, kacchan.”

katsuki leverages his feet on the mattress and prompts izuku to hover a bit, just enough to give him space to give the first thrust.
451
he pushes himself out and then up, seeing his dick disappear and move inside the omega and moaning, a possessive haze taking over him like a dangerous spell.
452
katsuki grunts, fingers leaving the omega’s clit to grab him by the waist with both hands and /hold him/ into place to firmly push his cock inside, unexpectedly overwhelmed by the animal need to fuck and claim and nothing else.
453
but izuku growls, scent turning momentarily angry, making the alpha whine and wip his head up to give the omega a confused look.

“i’ll do it, don't stop that,” the omega heaves, taking his hand and guiding it back on his pussy, over his engorged clit.
454
izuku digs his hands on katsuki's chest, holding onto him for support to then lift himself up with only the strength of his legs, slowly and torturously dragging his pussy over the barbarian's cock until only the tip remains inside.
455
then he lets himself fall back down, swallowing him back inside in one go.

katsuki’s eyes roll to the back of his head and stay there as izuku struggles to learn how to keep his balance and experimentally bounces up and down the alpha’s thick cock.
456
it doesn't take him long to find a rhythm that feels both brain-melting and eye-opening.

it has them both shaking, seeing stars, and the room soon fills with the obscene sound of slapping skin and squelching noises combined with their desperate moans and groans.
457
the alpha spanks him, one quick slap before gripping him tightly in his hand and squeezing until the plush of his ass spills between his fingers. izuku moans wantonly, and bounces even faster.
458
katsuki can physically /see/ the strain of izuku’s powerful thighs, muscles trembling and working under the freckled skin. if it wasn't impossible to get any harder than he already is, this would definitely do it.
459
“you're so gorgeous, izuku, you drive me so mad,” the alpha groans, meeting the omega thrust for thrust.

“kacchan, kacchan,” is all izuku can say, purring and far too gone to form any coherent phrases.
460
the alpha doesn't care, his mouth keeps sputtering words of adoration he can barely hear over the ringing in his ears that only gets louder as their lovemaking gets more frantic, animalistic and desperate.
461
izuku’s legs start to give in, and he has no choice but to allow katsuki to hold him steady and take whatever he has to give him.

he throws his head back and hollows his fingers into katsuki’s pecs, thighs tensing strongly before completely going lax.
462
the omega cries a searing whine, and his cunt clenches impossibly tighter around the alpha’s cock, and katsuki feels his knot starting to grow.

katsuki growls, and takes the opportunity to flip them both over the matters without pulling his cock out.
463
izuku doesn't even seem to realize what happened nor care. he just stares at the alpha above him with misty eyes under furrowed brows, with his mouth hanging open in a silent cry.
464
katsuki leans down to kiss his stomach, then lap at his tits and play with his nipples before finding the crook of his neck and sucking his scent glands.
465
the alpha’s knot starts threatening to catch on izuku’s abused hole, almost grown into its full size. izuku must feel it because he wraps his legs around his hips again, keeping him from going anywhere, and starts smelling remarkably appetizing, sweet and milky.
466
a sign that his body is ready to take the knot, to be bred. mated.

katsuki moans, hips stuttering, his moves becoming erratic and uncoordinated because his besotted brain can only focus on fucking and getting more of that hot and divine feeling curling in his belly.
467
he needs to spend his seed inside the gorgeous omega under him and making sure no one else can have him.

he needs to bite him.

izuku whimpers, and lolls his head to the side to show him his vulnerable neck, wordlessly inviting him, granting him the honor to make him his.
468
his knot pops, and he shoves it inside izuku’s hole in a single thrust, locking them together as he comes with a ragged moan.

katsuki dives down to press his enlarged fangs around izuku’s swollen scent gland and bite down /hard/.
469
the skin breaks, and the alpha tastes blood and mating oils on his tongue.

izuku screams and sobs, immediately orgasming when his alpha sinks his teeth on his neck.

the world is reduced to the sound of their hearts beating together as one.

royal omega izuku who is the promised bride to the alpha dragon king katsuki. they meet for the first time on their wedding day, when as part of tradition they bow to each other and then to their people, symbolizing the beginning
471
remember you can always support me on my ☕ if you enjoy my work ✨

472
the kingdom is still joyfully celebrating their marriage outside their window, toasting in their honor, dancing, and setting off dazzling fireworks into the sky.
473
inside their room, everything seems to be peacefully quiet, save for the purrs and croons coming from the newly mated couple on the bed.
474
the alpha tenderly laps at his omega's bloodied neck, careful not to irritate the skin any further and getting his saliva all over the bite wound hoping the curative properties of it will help heal it faster.
475
the knot will take a while to go down, but it's okay because izuku is still quite out of it. although he hasn't stopped purring, the barbarian knows his mate is still far from responsive right now.
476
with all the hormones and emotions rushing through them thanks to their new bond, even katsuki feels a little dizzy.

but he also feels happy, light-hearted, and peaceful.

/this is how it feel to be complete, he thinks. this is how it feels to have the world./
477
any adventure nor conquest will ever compare to the feeling of having izuku in his arms. to come home back to him, to win by and for him.

he waits patiently, scenting, licking, and kissing his mate, crooning and rumbling as he lets the warm fuzzy feeling in his chest settle.
478
"you smell happy," his omega murmurs, stirring in his arms.

katsuki stops licking at the bite to peek at him, finding those gorgeous grassy eyes already staring at him and instantly making his heart jump.
479
his knot was still buried deep inside the omega and /his eyes/ were what made katsuki blush. unbelievable.

"i am," he replies, leaning down to peck at his temple. "you back with me?"
480
"getting there," izuku says, trying to blink the haze away. he pauses when he hears how hoarse his voice sounds, and sighs. "no promises."

katsuki laughs and kisses him again. "something wrong with your throat?" he teases.
481
"i think your dick is so big it messed it up."

"nah, it was all that screaming you did."

"mmmh, my bad," izuku retorts, "you made it quite impossible for me to keep quiet."

"i'm not complaining," the alpha clarifies. "if anything, i can't wait to hear it again."
482
he playfully pinches one of izuku's thighs and the omega jumps, wincing when the swollen knot tugs at his sensitive entrance.

"we can talk about it when your knot goes down," izuku pouts.

katsuki kisses his shoulder as an apology, and izuku smiles, weak before his alpha.
483
the alpha shifts until he can hold his omega and stare at him without straining his neck. he tugs a green curl behind his ear and lets his big hand rest on izuku's cheek.
484
izuku smells like everything an alpha wants to smell on their mate: sweet notes of happiness mingled with soft and relaxed undertones, nothing but pure blissfulness and contentment.

a well-cared-for omega.
485
pride swells in the alpha's chest, and he whines like a puppy when izuku catches on to what he's thinking and works on pumping even more of that delicious scent.

they look at each other with a world of emotions pooling in their eyes but no words on their tongues.
486
they soon realize they don't need them; the bond tells them everything they need to know.

eventually, his knot goes back to normal, and he's able to slip his soft cock out. they both wince at the uncomfortable feeling, and his cum starts to leak out of izuku's pussy.
487
his alpha growls at the sight of his seed being wasted. katsuki has to admit that his feral urge to put his cock back inside and breed izuku all over again doesn't sound so bad right now.
488
but that's all quickly forgotten the moment izuku mewls a distressed cry at the loss of the knot.

he's quick to sit on the bed and scoop the whining omega into his arms, softly rocking them back and forth and rubbing their necks together, doing his best to soothe his mate.
489
a newly mated omega, especially one that was so restrained in this omega instincts and needs like izuku was, can have a hard time with losing the comfort that being knotted to his alpha provides.
490
katsuki needs to remind izuku's omega that he's there with him and not going anywhere, even when the knot is gone.

"it's okay baby, you're okay," the alpha whispers into his hair in between kisses.
491
izuku fusses for a few minutes until, after a lot of scenting and reassuring words, he relaxes again.

traditionally, a bowl with warm water and extracts of different relaxing herbs is left in the room near the bed to use, along with towels previously scented by the alpha.
492
he reaches out to grab one of the towels, dipping it in the water and squeezing the excess one-handed.

he starts from izuku's forehead, gently making his way downwards, patting away his warm skin to clean all the dried saliva, sweat, and tears.
493
he wipes his neck, careful around the bite, scrapping dried blood and apologizing with a kiss every time izuku winces.

he grabs a new towel then and repeats the process, now going across his chest, his puffy nipples, and his ribs.
494
when he reaches his thighs izuku starts purring again, and katsuki replies with his grave rumble as he wipes the mess between his legs —his alpha still throwing a fit about the misspent cum, but oh well.

"thank you, kacchan," the omega happily sighs, squeezing himself closer.
495
"how are you feeling?" katsuki asks, rubbing tender circles on the skin of his thigh with his thumb.

"my head got all fuzzy for a second. my omega really didn't like that," he says with a bashful smile.
496
"it's normal. the more your omega sees i ain't going anywhere after the knot is gone, it will calm down."

izuku nods, still looking somewhat embarrassed. he giggles when katsuki nuzzles his neck with a grunt and squirms when the alpha's nose tickles him.
497
"you're so different from everything i expected," izuku suddenly says.

katsuki raises his head and looks at him with a quirked brow, unsure. "what were you expecting?"
498
"omegas tend to fear alphas where i come from. we're separated from the moment we present and barely coexist together until we marry."
499
"socially, they're above us in every way, and we're taught they're selfish, violence-driven creatures that don't care for anything but their own pleasure and primal needs, which somehow omegas are responsible for."

"that sounds like a whole load of bullshit," katsuki growls.
500
"it never made sense to me that such savage-sounding beings were the ones in power, controlling everything and everyone. i grew up dreading the day of my marriage, and worried for the pups i would have to raise in a place where there was no kindness or fair opportunities."
501
he takes the alpha's face between his hands and caresses his scaled cheekbones with a tenderness that pulls a croon from katsuki's throat.

"turns out, i was worrying for nothing because the gods were good to me."
502
it makes the alpha's blood boil to think that there was ever a chance of izuku not finding his way to him.

of him marrying some bastard alpha that could have forced him into a life he didn't want,
503
mating and pupping him without consent and subjecting him to a role izuku never belonged to.

treating him without the care and respect the omega deserved, not acknowledging his potential nor giving him the chance to be his best, happy self.
504
"why does your father allow that?" katsuki asks in a tight voice. "king all might have always seemed like a reasonable alpha to me. i would have never taken him to be a cruel ruler."
505
"he's not, but it's hard to change the written and unwritten laws of a kingdom that was living in the dark for so long," the omega states. "before my father took the throne, the territory was submerged in chaos.
506
only those with the strongest magic and connections with evil could survive. alphas soon took over, opressing omegas and not holding back. my father has been slowly trying to heal our society, but it's not easy."
507
it made so much sense now. why did the king offer him izuku's hand in marriage the same day his parents announced he was ready to be wed.

he was trying to get him out of there, to give them a chance outside the limitations of a fractured society.
508
he knew katsuki would at least give him that.

"if your father is willing, i would like to speak to him about it. see if there is anything we can do to help the process," katsuki offers. "you know, so omegas don't have to grow up like you did anymore."
509
"kacchan," the omega whispers, going misty-eyed. "would you do that?"

"i hate knotheads who use their brute force to overpower others, and i hate unfairness even more. if anything, you've given me the perfect excuse to stick my nose into your kingdom's business," katsuki scoffs.
510
"i've been wanting to do that for a while now."

"kacchan if we weren't already mated i would make you bite me and knot me again right now," izuku says in all seriousness.

katsuki's scent spikes, interested. "what's stopping you, sweetheart?" he purrs.
511
"i'm sore," izuku grumbles, "but it's the good kind of soreness, like the one you have after you had a good training."

"those are the endorphins we are swimming on right now."

his queen chuckles. "could get used to those."
512
katsuki hums, a little smirk pulling at his lips. "yeah, me too."

the omega smiles, showing his cute little fangs that make the alpha's insides melt.
513
izuku reaches for his head and spreads his fingers through his messy hair. his blunt nails scratch his scalp, fingers exploring and playing with the strands, and katsuki's eyes nearly roll back when he scrapes right around his horns.
514
"these are so stunning," the omega murmurs in awe, now stroking the curved length of his horns with delicacy. "they might be my favorite part."

"because you haven't seen my wings yet," the alpha grins.

his mate's green eyes sparkle with excitement and izuku gasps.
515
"why don't you have them right now if you're half-shifted?"

"i can choose whether i want them out or not. but not all of us can, it requires a lot of practice, as well as perfect control of our magic," katsuki explains.
516
"they would have only gotten in the way tonight so i didn't summon them."

"i would have liked to see them," the omega pouts, earning a laugh from the alpha.

"i mostly have them when i'm on duty, i rarely ever show them at home, they're too big."
517
when izuku keeps his pout and blinks his big owlish eyes at him in a pleading way, katsuki knows this is probably only the beginning of many battles lost against his omega, and he can't even bring himself to care.
518
the alpha sighs, pretending to be annoyed as he gently places izuku on the bed and stands up.

"do you want to see them?"
519
katsuki is truly becoming obsessed with the way izuku's eyes light up when he's excited about something.

he hopes he can make it happen for the rest of their lives.
520
izuku excitedly nods, crawling to the edge of the bed and sitting on his legs, expectant and almost vibrating under his skin.

"spoiled brat," katsuki mumbles under his breath, but it's so fond it makes him smile.
521
the alpha turns around and takes a deep breath.

the familiar sensation of his backbones moving as they make space for his wings to come out tickles his skin.
522
katsuki's been shape-shifting since he was barely a baby. it's instinctual for most of them, a call from the magic flowing in their dragon blood and demanding them to never forget what they are and where they come from.
523
so its not surprising when in the blink of an eye his powerful wings are flapping behind him, stretching after being tucked away for so long.
524
he peeks above his shoulder when izuku doesn't make a sound, curious to see what reaction could his mate be having.

izuku just sits there, mouth slightly open and eyes wide open. he seems to be frozen, and the frown on his eyebrows makes katsuki uneasy in more ways than one.
525
his alpha starts spiraling. /"mate doesn't like our wings? are they not big enough? strong enough?"/

he keeps quiet as izuku steps out of the bed with slow moves, eyes glued to his wings that have stilled with katsuki.
526
hesitantly, izuku grazes the sturdy membrane of his wings with the tip of his fingers, shooting lightning bolts straight through the alpha's spine.
527
he thumbs the scales next, with the same care someone would have for something fragile despite them being so sturdy, and he plays with the sharp edges as if he is not afraid of getting cut.

"izuku?"
528
the omega doesn't answer, too engrossed in what he is doing. his palm smooths through the length of the bone structure, tracing the outlines of his massive wings.
529
izuku slides his hand from the bone to the membrane, and stops in the middle of his right wing, where scar tissue keeps scales from growing and thickens the skin in the form of a large star-shaped scar.
530
"you saved my life."

katsuki whips his head around. "what?"

izuku takes another while to respond, eyes fixed on the scar. the breath he takes before speking is shaky.
531
"the last day of war, when the battle was at its peak after my father was too injured to continue, an enemy soldier broke through my protecting spell and cursed me. they nullified my magic, and made me lose all my strength," the omega muses, still not looking away.
532
"i fell to the mud, helpless, feeling like venom was spreading through my body and draining the life out of me with it."

katsuki's heart starts beating faster, and his wings twitch in izuku's hands, restless.
533
"the soldier unsheathed his sword when i hit the ground, and i thought my destiny had decided i was going to die that day, on the battlefield, with my people. i tried to move but i was too weak— i turned to the sky to ask the gods for mercy, but suddenly, i couldn't see the sun."
534
"a beautiful wall of iridescent scales was above me, shielding me from the enemy's attack. i realized it was a dragon's wing when the soldier's sword tore it apart, letting the sunlight reach me again through a star-shaped wound."
535
the alpha's breath hitches and he turns around, facing the omega whose got tears running down his gorgeous freckled face.

"izuku," he whispers, shocked and feeling tears picking at the corners of his eyes.
536
"a warrior from the dragon clan had protected me from death, and i never knew who i had to thank until today," izuku mumbles in a shaky voice and with a wobbly smile on his lips.
537
"that act of valor gave me the strength i needed to get up again and go beyond everything i thought possible. he fought by my side until the end, when the dark lord fell and the air cleared with the roar of victory from our people."
538
he pauses, and stares like hes looking at katsuki for the first time all over again.

"but before i could ask him to remove his helmet and what his name was, he was gone."
539
"it was you," katsuki breathes, "the soldier that fought with me at the end…"

"we're a good team, kacchan," izuku chuckles wetly. "the gods don't make mistakes."

"oh, baby."
540
the barbarian wraps his omega in a tight hug, squeezing him with his arms and cocooning them inside his wings, protecting them from the world. he lets a couple of shocked tears fall while izuku can't see, shaking his head in disbelief.
541
"kacchan, thank you," izuku cries in his chest, "you saved me."

"don't-" katsuki has to clear his throat and wipe his nose to keep talking.
542
"there is nothing to thank for. how was i gonna marry you if you died that day, nerd? it was all written in the stars. i would do it a thousand times over again if it means i get to keep you in the end."
543
"i hope you don't have to," the omega sniffles, "i wouldn't want another war to fall upon us ever again."

"it won't," katsuki says, "but if the day comes, we will be ready."

"how?"
544
"my promise stands. if you wish to properly become a knight, when you say the word, i'll start training you myself," the alpha promises. "you have the guts, that much is clear." he chuckles.
545
"you're also fast, smart, and think quickly under pressure. you're a good strategist and you know how to use your damn sword, i think you'll be more than fine-"
546
izuku throws himself at him, wrapping his arms around his neck and catching him by surprise with a bruising kiss. the bond warms with the affection of a thousand unspoken words, and their scents blossom with sweetness.
547
"i love you," the omega whispers over his lips, staring right through him with those gorgeous green eyes he felt so drawn to when he first saw them glow with the fire of the bravery in his heart, even when everything seemed to be over.
548
he's fallen in love with them, and with the beautiful, mighty omega that gets his strength from wearing his heart on his sleeve.
549
"i love you too, izuku," he says, pressing his forehead to his mate's. "thank you for finding your way to me."

a firework bursts in the dawn sky, bathing them in soft lights, and the people cheer, blessing the union of their king and queen.

552
the king and queen end up spending ten days in their chambers.

when they finally come out of the room, the alpha proudly displays every bite, scratch, and purple blotch on his skin with a smug smirk.
553
izuku blushes and hides behind his mate whenever they pass someone who gives them a knowing look in the big royal halls.

"you're the queen now, izuku," katsuki reminds him. "if anyone dares to say anything about you i'll have them beheaded."
554
"kacchan!" izuku slaps his tattoed bicep, then grabs his arm between his and walks holding it. "you're not beheading anyone on my behalf, like, ever."

"we'll see."

izuku arches a brow but says nothing for a while.
555
the castle is considerably big, so it's odd for katsuki to be in silence for the rest of their walk toward the dining room after more than a week of listening to izuku's voice at every hour of the day —rambling, chatting, laughing, moaning or screaming, his mate is pretty vocal.
556
he senses something unusual in the bond and goes /ah./

"are you nervous?" the king asks.
557
izuku averts his eyes like he was caught, and purses his lips.

"we were in a bubble for the last few days, and they were the most wonderful time of my life. i guess I'm just afraid that now that our duties await things could change, you know… between us."
558
"izuku." katsuki stops and keeps his mate from hiding by cradling his face in his palms. he gives him a serious look. "even if things change, my love for you will never be any less, there is only space for growth in our path, together."
559
"but what if i'm an unsuitable queen?" izuku replies, eyes watery, "what if people don't like me, or if i'm not good enough for you in the end-"

"omega," the alpha says gruffly, stopping izuku's rambling immediately.
560
he brushes his thumbs under his mate's eyes, drying the tears with loving patience, then leaning down to scent him, cheek to cheek. "do you trust your alpha or not?" he scolds him, like a sire to his pup.
561
yes, kacchan," the omega mutters, "with my life."

"then don't doubt the omega I have chosen as a life partner, and to share the crown with. whatever difficulty comes our way, we will find a solution. this," he gestures to them both with his head,
562
"is no coincidence or mistake, and therefore, will last forever."

"even after we die, our souls are bound to find each other in eternity, our bond is a sacred thing. so use that smart little head of yours and listen to your mate."
563
he playfully bumps their foreheads together, and izuku giggles.

"how do you always know exactly what to say," he sighs, chirping when katsuki nips his cheek.

"i know my mate."

izuku smiles at him, dreamily and adoringly, and katsuki gets weak in the knees.
564
ugh, he's gone soft in less than two weeks.

"you little shit," the alpha grumbles, aggressively scenting the top of his curly head with his chin, green curls now adorned with a jeweled chain that hid in his hair and decorated his forehead with a delicate ruby.
565
"stop being so cute all the damn time."

"kacchan!" izuku bursts out laughing, not doing much to resist his mate's attack. "be careful with the headpiece!"

"ill give you as many as you want, don't worry about it."
566
the omega let out a high-pitched chirp, completely delighted, and katsuki takes pride in it.

heh, that's more like it. he wants these walls to bounce off the sound of izuku's voice for the rest of their lives.

"there you are, lovebirds."
567
mitsuki's teasing voice interrupts their little moment. izuku is quick to scramble out of his husband's hold and stand straight beside him, which makes katsuki growl and send his mother an annoyed glare.
568
she's not alone. his father, king all might and queen inko come right behind her, all watching the newly-mated couple with an awed face.

"the hell do you want, hag," katsuki gruffs, sneaking his arm around izuku's waist and pulling him close to him.
569
izuku squeaks and whispers his name in a reprimanding manner, but katsuki only presses him closer.

"we were wondering what was taking you two so long," she says, grinning, "since you were expected at the breakfast table an hour ago."
570
"it took us some time to leave the bedroom," katsuki nonchalantly says.

"oh my gods, kacchan!" izuku scolds, flushing a deep red. he addresses everyone when he bows and says, "we are so sorry you had to wait-"
571
"oh honey, it's alright, i'm just teasing," mitsuki smiles, making a dismissive gesture with her hand full of rings, bracelets clanking with one another as her arm moves, "i knew katsuki would become an animal when he found his mate."
572
"all of that pent-up energy and bad temper, my goodness, it was about time for him to do something productive with it. tell me, did you use that nullifying fertility spell or should i expect a grandchild soon?"
573
izuku's eyes widen impossibly big at the former queen's straightforwardness, and his scent turns awfully embarrassed, matching his red cheeks and ears.

"i- no, i'm not-"
574
"stop stressing my omega out!" katsuki barks, snapping his teeth at his mother and protectively curling around izuku as if she were a threat.

he can see queen inko stifle a laugh behind the palm of her small hand.
575
his father sighs, sending all might an apologetic look, but all might just politely smiles, fondly watching the scene.

mitsuki looks completely unamused when she says, "don't be such a guard dog, look at the poor thing, you're hogging him all to yourself!"

"he's mine."
576
"he's my son-in-law, i want to have him for a little while too, you brat."

katsuki narrows his eyes. "he's /my mate/."

"uh, kacchan?"

"not now baby, someone wants to steal you from me."

"for the love of-"
577
"okay!" masaru claps his hands together loudly, "how about we continue this discussion at the table?" he turns to them and says, "your breakfast must be served by now." he looks at his son and adds, "again."
578
katsuki grunts under his breath just for the show of it, because he starts walking towards the dining room with the rest of them just like his father asks, with izuku still attached to his hip.
579
"i'm glad to see you two seem pretty happy so far," king all might comments quietly as they walk side by side.

Izuku beams at him. "you were right dad, kacchan is amazing."

katsuki arches a brow. "your dad said i was amazing?"
580
"well," the omega starts as he tries to hide a smirk, "he said you would be a very good mate for me."

"oh?" the alpha says, grinning at the other king , "glad to know i gained the king's blessing while trying not to get killed."
581
"what better setting to know the true nature of a man?" all might replies. "besides, not anyone could keep up with my feisty omega of a son, i knew that much. any lesser man would have been undoubtedly intimidated."
582
"if you couldn't handle him, then i had to admit that i would have been very disappointed on you, young bakugou."

"dad!" izuku groans.
583
"hell yeah, i'll keep up with him," the barbarian smugly smirks, discreetly pinching the omega's ass under his clothes and making let out a surprised (not displeased) chirp, then send a murderous glare his way. katsuki cackles.
584
"i think i've been doing a pretty good job so far, haven't i, darling?"

"we could say that…"

"oh but izuku looks like the sweetest little thing," mitsuki coos, walking through the big wooden doors of the dining room. "i bet katsuki is the real pain in the ass."
585
katsuki is too busy trying to pick up the different smells coming from the table to give her a snarky reply. his stomach growls when his nostrils are filled by the smell of freshly cooked food. he realizes how little they have been eating during the mating period.
586
it's not uncommon for newly mated couples to reduce food intake during that time, since they're much more likely to be busy with other, uh, /activities/ in those days. they ate light fresh foods that were left outside their chambers at every meal,
587
and honestly he doesn't think they would have been able to stomach anything else.

but now the thought of izuku not eating properly for so long is making him grow mildly uncomfortable by the second, and he's overcomed by the need to see his omega eat before anything else.
588
he eyes him through the corner of his eye as izuku animatedly chats about something with his father, and the alpha tries to assess if izuku has lost any visible weight.

he's horrified to realize he has.
589
it's nothing alarming, just a bit less fat on his perfect thighs and pudgy tummy, heavenly visible through the thin fabric of his light flowy pants and light shirt.

with how much physical activity they had, plus the reduced meal portions, it's no surprise izuku looks thinner.
590
and even when he still looks perfectly healthy, katsuki's alpha is about to pop a vessel.

with the conversation still flowing amenably, they go towards their designated places at the table, with katsuki and izuku at the head.
591
the service approaches to serve the dishes, and katsuki's foot taps impatiently on the floor.

"my king?" Izuku quietly whispers at his side, big worried eyes looking at him. "why do you smell like that, are you okay?"
592
"yes brat, you're stinking up the damn place," his mother agrees. everyone quiets down and all eyes turn to him.

he ignores his mother to reply to his mate on a low gruff, "i'll be better when you eat."
593
his mother's gaze quickly fills with silent understanding, and to his annoyance, a slow grin spreads across her face as she quirks an eyebrow at him.

"oh you're so much worse than i thought," she says, shaking her head.
594
"poor izuku is going to have to live with you breathing down his neck, won't he."

the alpha blushes. "shut up, hag."

izuku just looks at them with confusion, turning to his mother with an innocent frown. inko just smiles, also knowingly, and izuku just blinks.
595
"honey, let katsuki alone, he's just taking care of his mate like a good alpha," masaru gently nudges, "isn't that what we taught him?"

"yeah, yeah, i guess so," mitsuki sighs, putting her elbows on the table and resting her cheek against her hand.
596
"how did he treat you during the mating period, dear?” she sweetly asks izuku, “was he good or do i need to cut his dick off?”

masaru sighs and rubs at his temples, the poor omega can only let out a nervous laugh as he tries to send a panicked glare to his husband.
597
“oh no, no need, he was wonderful,” izuku assures, “please don't do that.”

“are you sure you're okay, baby?” inko chimes in, worriedly touching her son’s arms and looking his cheeks. “you look like you've lost some weight.”
598
katsuki has to suppress a growl on the bottom of his throat and disguise it as a cough when his mother kicks him under the table.
599
“oh inko, don't worry about that. it’s completely normal for omegas to come out a bit less chubby after the mating periods around here,” the former queen dismissively says, “our alphas are known to have the same stamina in bed as in battle, after all.”
600
inko chokes and her cheeks turn bright red, “oh dear, uhm…”

all might chuckles besides her. “don't worry about the kid, he’s more than fine. don't you see he’s glowing?”
601
izuku can't take it anymore and hides his face on his alpha’s naked shoulder, mumbling and blushing, involuntarily chirping. katsuki kisses the crown of his head and proudly grins.

“he will put on the weight soon,” katsuki assures.
