@deerop0: “Why don’t you make it your ow...

“Why don’t you make it your own?” Izuku asks, playing with his hands. “I could help you decorate, if you want…”

Katsuki raises an eyebrow. “So you plan on keeping me around after tonight?”

Izuku laughs. “Depends on how good you are, I guess,” he purrs, slipping into his work persona.

“Yeah?” Katsuki says, his voice low as he walks over, and oh god, Izuku is just now realizing how much /taller/ Katsuki is than him now.

The omega doesn’t really have time to overthink it before Katsuki is lifting him effortlessly, coaxing him to wrap his thick thighs around his small waist.

Izuku grabs onto Katsuki’s broad shoulders for purchase, blushing as they lean in to let their lips meet.

It turns into something more pretty fast - tongues working against each other, Katsuki squeezing roughly at his ass, and Izuku’s mind is warring between ecstasy and total, utter terror.

“M-my room’s down the hall,” Izuku pants against his lips when they break apart for a moment.

“Say less,” Katsuki laughs, leaning in to kiss him again as he walks them down the hall.

Izuku’s bed is plush, and he sinks into it with a purr when Katsuki puts him down, making sure the omega is watching before he pulls his shirt over his head effortlessly.

“Your entire existence is unfair,” Izuku whines, biting his lip as the alpha crawls over top of him and reclaims his lips like he can’t get enough of him.

“I’m yours for the night, baby,” Katsuki breathes against him, and Izuku is gone.

Ever since he knew what love was, knew what sex was - he’s always defaulted to Kacchan when he thought of those things, both romantic and sexual alike. The alpha’s sharp tongue, his bold gaze, his smoky scent.

When the blond left for UA, Izuku had felt an awful sense of jealousy and /abandonment/, and he’d watched the explosive hero take the world by storm from the confines of his house and ordinary school.

So hearing those words - after years of pining - is like a punch to the gut.

Because that’s what this is, isn’t it? Just a night. Simple and fleeting. Nothing more. Maybe they’ll never see each other again after tonight.

Izuku hates how emotional he’s always been, and he wants to bury his face in the ground when his eyes start to sting.

He lets out a hiccup-y sob and his face crumbles, and Katsuki’s own turns to a look of panic.

“W-what’s wrong?” The alpha asks gently, leaning up to give him space. “Did I do something wrong? Fuck, I’m sorry.”

“You didn’t do anything wrong!” Izuku assures him, babbling a bit. “I-I just, I’m stupid and emotional! You used to call me a crybaby, remember?”

“S-shit,” Katsuki curses. “Fuck, this was so out of line of me. Fuck.”

Izuku wants to slap himself, because here he is ruining the night. His one chance of having Katsuki the way he wants him, and he’s ruining it.

Thanks, universe.

“Stop saying that,” Izuku breathes. “Please. I want this, I want you. It’s just…”

Katsuki looks up from where he’s withdrawn to the end of the bed, looking upset himself.

“I don’t understand, then,” the alpha says cautiously, tilting his head like a confused dog, and Izuku really needs him to stop being so goddamn kissable.

“I -,” Izuku starts, taking a deep breath. “I’m a virgin. Yeah, laugh all you want.” He wipes his eyes. “A-and the idea of this being a one night thing is… not what I wanted. Or hoped for. I know, I’m stupid. You’re, well… you. And I’m just me.”

Katsuki’s eyes widen and he’s crawling back up the bed to kiss Izuku’s forehead gently.

“Fuck, dumbass - those words were just sex talk. Like ‘I’m yours to do whatever you want with for the night’ type of shit,” he laughs breathily.

“I planned on takin’ you out for dinner this weekend, if you’d agree. I… I actually didn’t know if you would be okay with this being more than a one night thing. But hell, we don’t have to do /shit/ tonight, baby. Let me court you properly, let me -“

“No,” Izuku interrupts. “I want you to fuck me like you said you would.” His tears dry up, and he gains his sparkle back a bit, because Katsuki /wants him too/, and that changes everything. “And then I want you to court me.”

Katsuki just looks down at him for a second before Izuku surges up and recaptures his lips, wrapping his arms around the alpha’s neck to pull him in deeper.

“Aren’t you supposed to ‘atone for your sins using your mouth’, or something?” Izuku murmurs teasingly.

Katsuki groans. “You’re a little minx for a virgin, you know that?”

“It’s kinda needed, for my line of work,” Izuku says sheepishly. “Gotta act like you actually want your customers around.”

“Mm, I’m glad it wasn’t an act for me,” Katsuki says gently, pecking his lips.

“It’s always been genuine for you,” Izuku says sincerely.

TBC

“I want you to sit that ass on my face,” Katsuki says, effectively ending whatever sappy bullshit they were on.

Izuku’s mouth closes with an audible click, and he nods enthusiastically. “Yeah, yes, uh-huh.”

Katsuki lays back on his bed, looking entirely too sexy and ethereal, and Izuku can’t really believe he’s seeing /Kacchan/, his ex-bully turned famous pro hero, laying in his bed waiting for him to sit on his face.

Working down his leggings and panties, Izuku shyly looks away from Katsuki’s heated gaze, those eyes expectant and entirely too cocky.

“Do you want me to… hover, or like, actually… /sit/?” Izuku asks nervously, playing with his hands.

“Sit on my face means /sit on my face/,” Katsuki says firmly. “I’m a goddamn pro hero. Sit that ass and pussy on my face. I won’t break.”

“Oh my god,” Izuku whines, covering his face. “You’re too much!”

Katsuki’s smirking when Izuku drags his hands away from his eyes. “I’m just lettin’ you know.”

Izuku lifts his oversized shirt off quickly, suddenly feeling much too hot in the cool AC of his apartment.

No one warned him quite how embarrassing it would be to position himself over someone’s chest, his ass all up in their face as he faces away, grappling at their thighs for purchase.

“I-is this okay?” He asks meekly, his voice quiet.

“More than okay,” Katsuki groans, and Izuku can feel his eyes burning a hole into his ass. “C’mon, let me eat you up.”

With that, Katsuki grabs at his hips and /yanks/ him down, taking on the full weight of the omega’s body.

Izuku squeaks when Katsuki immediately gets into it, licking a wet trail from his clit to his opening, moving his body like it’s nothing.

“O-oh my god!” The omega groans, his hands balling into fists on Katsuki’s solid thighs.

Katsuki just hums in agreement, eating him out like he’s been starving for this for /years/.

He continues to work his tongue at Izuku’s clit, sucking and licking at it gently, bringing forth waves of slick that coat his chin.

Izuku would be embarrassed about it, but Katsuki seems to revel in the feeling of pleasing him, coaxing him to grind against his face with abandon.

It’s not long before Izuku feels fucked out just on that tongue, his pussy pulsing, begging for something to fill it up.

“K-kacchan,” he pants, still moving back and forth on his face like it’s nothing. “I need - something! P-please.”

It feels like Katsuki’s lips quirk up against his cunt, and suddenly that thick, wet tongue is working itself into his slicked hole.

“O-ohh, fuck,” Izuku whimpers, his eyes fluttering closed with pleasure.

Katsuki just grabs at the back of his thighs and lifts him up and down like he’s weightless, fucking him on his tongue.

Izuku doesn’t think he’s gonna survive this ordeal, honestly - Katsuki is too much, too eager to reduce him to a drooling mess of nerves and pleasure.

After a moment, the omega begins to move himself in tandem with Katsuki’s strong arms, that tongue pistoning in and out as he rides it, Katsuki groaning with every burst of fresh slick he’s gifted with.

One of the alpha’s thick fingers rubs along his inner thigh, reaching to gently rub at his clit and little dick, and Izuku can’t help but wail and clench around his tongue, his body vibrating as a supernova of an orgasm takes over his body, stars bursting behind his eyelids.

Katsuki coaxes him through it, his finger and tongue eventually slowing to a stop as Izuku whines with overstimulation.

Izuku’s eyes open slowly, and they flicker away from where he’d been staring at the sheets as he was thoroughly taken apart, and noticed how /hard/ Katsuki is.

And god, is that thing even a dick at this point, or is it considered a third arm? It’s strained against the alpha’s sweats angrily, and Izuku gulps in both arousal and terror, imagining it sliding into his little pussy and taking him apart, ruining him for anyone else.

Giving himself an inward pep talk, the omega tentatively places his hand on the bulge, stroking it determinedly.

Katsuki lets out a rumble behind him, his dick jumping like it’d been waiting for his touch for hours.

The alpha maneuvers them easily, flipping Izuku around so he’s straddling him face-to-face, and the omega flushes at how wet Katsuki’s lower face is.

Noticing the look, the blond makes a show of licking it all up, maintaining eye contact.

“Gross,” Izuku whines, no real heat behind his words as he watches keenly.

“I’ll have to eat your ass next time, show you a real good time,” Katsuki replies casually, his eyes playful.

Izuku burns bright red. “Oh my god.”

Leaning down, the omega decides /fuck it/, and kisses Katsuki deep, tasting himself on his tongue and surprisingly he’s not entirely disgusted.

They lazily make out for a few minutes, the room echoing with their wet kisses and the whir of Izuku’s ceiling fan.

Izuku whines in protest when Katsuki eventually pulls away, rubbing circles at his hip.

“You gonna let me take you apart for real now?” The alpha asks, grinding his erection against Izuku’s ass for emphasis.

TBC

Those words do Izuku in, and he eagerly nods his head, unable to form the right words to convey how much he fucking wants this.

He’s slicker than he’s ever been, and he can feel it ruining Katsuki’s pants, but he’s too horny to give a damn.

“Want it, alpha,” Izuku whines, grinding back in emphasis, and the blond’s cock twitches eagerly against his pussy through the barrier of his sweats.

“I fuckin’ fantasized about you in this position every day when we were in middle school - fuck,” Katsuki groans.

“Shit,” Izuku whimpers, reaching back to pull the alpha’s pants down just enough to let his dick spring free, angry and thick. “I wish you would’ve just /told/ me. I would’ve never left you alone.”

Katsuki laughs. “Middle school me always thought you’d never see me that way - so I pushed you away. Never said I was emotionally intelligent.”

“Clearly not,” Izuku teases, stroking him from base to tip, his fingers not even touching around the girth.

“Somehow, we ended up here,” he continues, pressing the tip of that pulsing cock to his soaked entrance, letting it rest there, teasing. He’s slick enough for it to slide against his folds easily, getting the entire length nice and wet. “I’m glad, Kacchan.”

“Who would’ve thought,” Katsuki says, throwing his head back against a pillow in pleasure, from the way Izuku’s heated pussy throbs against him. “I’m glad or whatever too, nerd.”

When the head of Katsuki’s cock catches on his opening on another pass, Izuku takes it as a sign to sink down onto the length with one smooth down thrust, letting out a breathy moan at the stretch, thankful that Katsuki took his time to prepare him.

Katsuki, who’s looking up at Izuku like he’s some type of angel, his mouth open with a silent groan, his eyes fluttering closed in pleasure.

“So fucking - warm and tight,” the blond grits out, squeezing Izuku’s hips firmly. “Perfect fuckin’ pussy.”

The omega squeezes around him at the praise, a flush rushing to his cheeks, because he has one of the top heroes under him, telling him how good his cunt feels.

Dreams do come true.

With an iron grip at his waist, Katsuki begins to help Izuku move up and down on his frankly huge cock, the omega’s drooling pussy easing the way. It’s a stretch, but it’s an /amazing/ stretch, the two of them joined together in the most intimate of ways.

Izuku’s hands rest on Katsuki’s generous pecs, copping a squeeze every time Katsuki fluidly fucks up into him, the wet sounds of his pussy swallowing every thrust echoing around the room.

Leaning down, Izuku catches Katsuki’s mouth, their lips dancing against each other as they move together perfectly.

“Why don’t you give me a show, baby?” Katsuki pants when they pull apart. “Play with that clit for me, hm?”

The alpha starts moving Izuku up and down, like a living flesh light, doing all the work easily as he looks up at Izuku expectantly.

With trembling fingers, the omega reaches down and circles his middle finger around his sensitive bud, letting out a tiny whimper.

“You’re gonna cum on my cock,” Katsuki says firmly, watching intently. “I’m not fuckin’ finishing until you’re completely fucked out.”

“Fuck, yes,” Izuku groans, feeling his insides clench at those words. “Ruin me, alpha!”

Katsuki must take those words as a challenge, because before Izuku can get out another word, he’s being moved around like a doll, and he’s suddenly on his knees, his ass high in the air as he scrabbles at the sheets.

With a growl, Katsuki mounts him from behind, his cock re-entering with an easy glide, and Izuku can do nothing but hold on for the ride, clutching onto a pillow with one arm and reaching back under himself with the other, continuing to work over his clit.

“You look good like this,” Katsuki grunts, his heavy balls slapping against Izuku’s ass. He squeezes one of the omega’s ass cheeks for emphasis, slapping it roughly, and Izuku just knows it left a mark - he can’t wait to admire it in the mirror later.

“You’re fucking me so good,” Izuku whines back, pushing back against every strong thrust as best he can in Katsuki’s strong hold. “So big, alpha, fuck.”

He knows he’s blubbering at this point, but he can’t help it. It’s too good.

“Tell me what you want, baby,” Katsuki says roughly, pushing in all the way and grinding his hips in teasing circles, stretching Izuku’s poor little pussy to the max.

“Want your knot!” Izuku begs, petulantly trying to fuck back. “Fuck me!”

“You’re not getting my knot until you cum on it,” Katsuki growls, biting his lip at the way Izuku’s warm cunt throbs around him.

Izuku nearly sees stars as he continues to rub at his clit furiously, and Katsuki continues his brutal pace once he’s sure his message is clear.

The feelings of fullness, overstimulated pleasure, and the orgasm growing in his abdomen are enough to send Izuku over the edge, and he lets out a noise he’s sure he’ll be embarrassed about later - a high-pitched omegan squeal as he clenches around Katsuki’s thrusting cock.

He feels a warm rush of slick gush out around the length inside of him, soaking Katsuki’s pelvis and balls, and he’s pretty sure his bed is going to need a thorough clean after this.

“Alpha, alpha - knot!” He whimpers through the waves, nearly mad with need.

“I got you, babydoll,” Katsuki says, the swell of his knot now impatiently pushing against Izuku’s folds with every thrust.

It’s big, bigger than Izuku anticipated, and he’s never taken a knot, but he knows he needs it more than anything right now.

It takes a bit of working, but eventually the knot slips in with a harsh thrust from Katsuki, Izuku bearing back with his eyes squeezed shut.

The feeling of hot cum flooding his insides is indescribable, and he goes boneless against the bed, feeling thoroughly satisfied.

He’s already asleep by the time Katsuki arranges them into a more comfortable position to wait for his knot to go down, his cock still pulsing streams of cum into his eager body.

Izuku chews on his bottom lip nervously before hitting “post”, immediately squeaking and throwing the phone away from him.

After a minute, non-stop notifications start pouring into his phone, and he covers his eyes with a groan, smiling to himself.

“Dear Kacchan/Dynamight/Katsuki: These past three years have been the happiest of my life. Where do I even begin? I could mention our trip to America last year, where you nearly fell into the Niagara Falls trying to catch my engagement ring when it fell off.

You succeeded, by the way. I could also mention our hiking trip in the mountains shortly after we met - you had to carry me halfway through the trip, remember? I just couldn’t keep up with your pro hero stamina, you’d said.

I flicked you on the forehead and pouted until you hoisted me into a bridal carry and kept walking like nothing happened. Or, should I go on about that time we went to Disney world and you were terrified of those little animatronics on “it’s a small world”?

We had to pay for the replacements, since you blew them up. The thing is, I have countless memories with you, and all of them mean the world to me.

I could write down every little detail of our lives since we met and still not be satisfied, because we have so many years and memories ahead of us. Every short moment I’ve spent with you has lasted a lifetime, and I’d happily live them all over again.

Every minute spent with you is a moment I’ll treasure forever.

…And I think every moment spent with you and our baby will be even better.

Happy Father’s Day, babe!❤️”

Izuku sits on their couch and waits, absentmindedly rubbing over his stomach. It’s still flat, but he thinks he can feel the tiniest of bumps forming - but maybe that’s just wishful thinking.

The distant sounds of explosions has him perking up, and he looks out the window-walls of their penthouse apartment, squealing as a person - his husband, he’s absolutely sure - soars through the air, riding a trail of fire and speed as they make their way closer.

The alpha lands on their balcony, the impact nearly shattering the windows right then and there.

The sliding glass door is ripped open to reveal a panting blond, his eyes crazy with emotions.

He’s crying, Izuku realizes, and he immediately rushes for his mate, who wordlessly scoops him up into an effortless hold, burying his face in his chest with a whine.

The omega wraps his legs around his husband’s waist and runs a soothing hand through his thick hair.

“You’re not fucking with me?” Katsuki finally says, his words shaky.

“You’re gonna be a daddy,” Izuku confirms, tearing up himself. “Sorry I kept it from you. I wanted to surprise you…”

“This is the best day of my fucking life,” Katsuki growls, carrying Izuku to their bedroom with a desperate kiss. “About time you got knocked up.”

Izuku rolls his eyes. “We’ve been trying for two months, dummy!”

“Two months too long.”

Izuku giggles, throwing his head back and wiggling his eyebrows up at his mate. “Are we gonna celebrate, or what?”

“Baby, we’re gonna celebrate all night long,” Katsuki says, pulling him in for another kiss.
