‼️underage, cheating (Deku cheating on his husband)

The first time Izuku sees him, Katsuki is working on his parents’ car, shirtless and laying beneath the undercarriage, rock music playing from the garage.

It’s a clear, hot summer day, the sound of sprinklers and the smell of food on hot grills filling the neighborhood.

Izuku and his husband moved here just two days ago, leaving the big city for the suburbs to finally start a family.

It’s the perfect neighborhood, really. Big houses, pristine lawns, lots of families with kids. It’s ideal, and Izuku has never been more bored and unhappy with his life.

Until now.

He tilts his head to the side, sunglasses covering his eyes as he sunbathes by the pool and creeps on the man working on his new neighbor’s car.

He bites his lip at the bulge in the alpha’s gray shorts - he’s big. His arms are big, too, flexing as he works.

Who is he? He must be the neighbor’s friend, a mechanic of some sort, and can you blame Izuku for staring? His husband’s the “missionary for procreation only” type, and he’s never even made Izuku cum. Sex with him is like a chore, and he’s out of town for business, thank fuck.

His husband being gone means he doesn’t have to lay in bed like a starfish and fake moan until the asshole’s mediocre cock spills inside of him.

Izuku shakes his head, focusing on the ripped man under his neighbor’s car again, hungrily watching the sweat drip down his arms.

“Brat!” Someone calls from the garage, and Izuku raises an eyebrow. “Dinner’s ready!”

The man grunts and pulls himself out from under the car with those big arms, and Izuku nearly chokes on his own spit when he stands up.

Because that’s a kid. A ripped, tall one, yes, but obviously a teenager. God, he hopes he’s 18. For his own morality.

And Izuku has never felt more ashamed than he does right now, because his pussy gives a valiant twitch at how handsome he is.

Cut jawline, smooth skin, broad shoulders, a tiny waist with washboard abs. Fuck.

“Coming, you old hag,” the (boy) shouts, voice deep and baritone.

Izuku swallows, nearly jumping out of his own skin when those sharp eyes wander over to him.

He wants to look away, he really does, but it’s like he can’t, their eyes meeting through Izuku’s dark sunglasses.

The boy’s eyes widen a bit, his mouth falling ajar just a fraction, and a deep blush stains his cheeks, still a bit chubby with baby fat.

It’s over just as quickly as it started, the boy looking away and hurrying inside after his mom.

His mom, who’s probably about ten years Izuku’s senior.

Izuku groans, throwing his arms over his eyes as he tries to forget what just happened.

-

There’s a knock on the door the next day.

Izuku is wearing soft leggings and a cropped hoodie, following along with some preppy, soulless yoga video he found online, and he jumps out of his downward dog pose when the door is pounded on.

He takes a swig of his lemon-infused water, prancing to the door with a soft “coming!”

He plasters on a cheery grin when he opens the door, keeping it on even as his stomach drops.

Because it’s the neighbor kid, carrying a tinfoil-covered bowl of food, a pretty blush and scowl combo on his face.

“Hi there!” Izuku chirps, his smile turning genuine when the young alpha’s eyes widen a bit.

“Hi,” the boy mumbles, shuffling his feet cutely. “My mom wanted me to, um, drop this off. As a house-warming thing. Or some shit.”

“Oh,” Izuku breathes happily as he takes the dish. “That’s so sweet of you!”

Izuku’s words are gentle, making sure his soft, pleased omega scent is pumping out on full blast.

He’s a horrible person.

“Tsh,” the boy sneers, face red. “Wasn’t my idea.”

“But you’re sweet for coming, anyways,” Izuku says, looking up at the alpha from beneath his lashes.

The blond is tall, Izuku’s head only reaching his chest. It’s such a perfect size difference. The alpha could so easily manhandle him, bend him over, hold him up as he -

“Whatever,” the boy growls, but he preens quietly at the older’s praise.

“Tell your mom to come by whenever she needs anything, okay?” Izuku says cutely, scrunching his eyes and giving the young alpha a sunny smile.

“Um, o-okay,” the boy stammers, coughing. “I’m, uh, Katsuki, by the way. Katsuki Bakugou.”

“It’s nice to meet you, Kacchan,” Izuku giggles, throwing in the cutesy nickname just to be mean. “I’m Izuku.”

It works, the blond’s face turning beet red. God, Izuku wants to sit on it.

“I’m fifteen, not six!” Katsuki barks.

Oh god. Oh fuck.

Izuku swallows, the flirtiness leaving his body with the quickness.

“Well, it was very nice of you to stop by,” Izuku says, voice wobbly. “Bye!”

He closes the door in the boy’s face, sprinting to the kitchen and sliding to the floor, nearly hyperventilating.

Fifteen. Fif-fucking-teen.

Izuku shakes his head. Okay, now he knows. He didn’t know, okay? It’s fine. Now that he knows Katsuki is underaged, he won’t creep on him, he won’t flirt with him. Hell, he won’t even interact with him without the boy’s mom around. It’s all good.

Izuku’s married, anyways. He’ll most likely be swollen and pregnant in a few months, baby-trapped into staying with his asshole of a husband who he’s pretty sure is fucking his secretary on the side.

Izuku gets up, splashes some cold water on his face, and continues his yoga video like nothing happened.

The food on the counter smells amazing, Izuku’s stomach rumbling as the scent wafts into the living room.

“Fuck,” he sighs, dragging himself to the kitchen and preparing himself a bowl.

It’s Katsudon, and the first bite is divine, leaving Izuku’s eyes wide as he shovels more into his mouth. He nearly finishes the entire dish, feeling full and sated afterwards.

That’s when he notices a small note hidden beneath the tinfoil.

‘My son, Katsuki, made this just for you, not that he’ll tell you (I think he has a puppy crush)! Welcome to the neighborhood! - Mitsuki & Masaru Bakugou’

Izuku groans.

(Cw: Izuku’s OC husband is sexist af)

Izuku’s husband arrives home three days later, wearing a perfectly pressed suit, his cologne completely overpowering his natural scotch alpha scent.

The mood sours as soon as he enters the house, slamming his bag near the front door and stomping inside with his stupid dress shoes.

Izuku’s stomach clenches with anxiety, tightening his apron around his waist as he sautés vegetables on the stove.

There’s tension in the air when the alpha walks into the kitchen.

“I texted you that I was on my way home an hour ago,” Ronin says, voice tight. “And dinner isn’t ready?”

“I’m sorry,” Izuku says, keeping his calm. “It’s almost done -,”

“You know how fucking stressful my job is?” Ronin nearly shouts, running a finger along the counter top and grimacing. “And my wife can’t even clean the goddamn house and have a hot meal ready for me when I get home from my business trip?”

Izuku bites his tongue, not in the mood for a screaming match that’ll end with him sobbing and calling his mom, listening to her pleas for him to just leave Ronin and come home.

Plus, imagine how shitty of an impression a fight would leave on their new neighbors.

The silence stretches on for a tense minute, Izuku fighting every muscle in his body to not turn around and scream in his husband’s face.

“I’m taking a shower,” Ronin says tersely. “Have dinner done by the time I’m done, and take my bag into our room.”

“Yes, sir,” Izuku bites out sarcastically, quiet enough for his husband not to hear, not missing the way Ronin’s eyes narrow at him before walking away.

Izuku lets himself deflate once he’s alone again, finishing up dinner and plating the food.

He carries Ronin’s bag to their room, unpacking the alpha’s clothes and throwing them in the hamper before carrying it off to the laundry room.

The omega startles when a pair of strong arms wrap around his from behind, lips pressed to his neck.

“Now that’s what I like to see,” Ronin whispers against his skin. “Come eat dinner with me after you’re done cleaning.”

It’s not a request, so Izuku swallows down his retort and nods wordlessly.

Ronin squeezes his ass before walking away, leaving Izuku nauseous.

Sighing shakily, Izuku shakes out a few shirts, eyes widening when a scrap of pink fabric falls to the ground.

His heart is in his throat as he picks it up, examining the skimpy panties.

“Oh,” he breathes, eyes watering.

He’s not sure if he’s upset or /relieved/, both emotions flaring up in his chest, warring with one another.

On one hand, he wants to curl in on himself and sob, and on the other, he feels like he can finally /breathe/ again.

He’s only twenty-five, marrying the then thirty-nine year old Ronin when he was twenty, enamored by the financial security the older man offered along with the sweet words he’d whispered and the gentlemanly way the alpha had treated him when they first met.

He’s still young. He can move back in with his mom, go back to college for hero support tech like he’s always dreamed of. He had to drop out when his mom lost her job and could no longer send him the scraps of extra money that she could scrounge up.

So, he left school and landed a low-paying job at a coffee shop, where he met Ronin, dressed to the nines and arriving for his black coffee at 7AM sharp. Nineteen year old Izuku had swooned, the thirty-eight year old alpha talking sweet, leaving him notes and flowers every day.

And now he’s here, financially trapped by the CEO of one of the biggest hero tech support companies in the world. The irony was never lost on him.

Ronin won’t allow him to get a job, insistent that he makes more than enough himself (true), and that Izuku has to prepare to be a stay at home mother (incubator).

Izuku takes in a shaky breath, unloading the last of the laundry into the washer and tucking the pair of panties behind the machine for safekeeping - Ronin will never find them. He insists that doing laundry is an omega’s job.

He washes his hands and sits down at the table where Ronin is waiting, giving the man a fake, pretty smile.

“You’re so beautiful, Izuku,” Ronin says, voice buttery. “Especially when you do as you’re told.”

The alpha is baiting him, Izuku knows. The man loves to gaslight him, calling him a crazy, omega bitch when Izuku finally snaps and barks back.

Instead of humoring him with a smart reply, Izuku digs into his food, wishing he’d spit on Ronin’s plate beforehand.

Izuku turns his back to his husband when the alpha tries to initiate sex that night, earning him a hiss of “barren bitch” in his direction.

Izuku holds in his retort about how the doctors all day he’s perfectly fertile and it must been an issue with his husband’s sperm.

He’s always wondered why Ronin never had kids before they met, and he nearly laughed when he finally realized that the man had pursued him simply because he’s young and in his prime, hoping he could get a younger omega pregnant.

“Not my fault you’re shooting blanks,” Izuku murmurs under his breath.

Once Ronin begins snoring, Izuku slides out of bed, pulling on an oversized cardigan and walking outside into the night air.

He sits on one of their poolside lounge chairs, listening to the nighttime bugs hum peacefully.

He hears a shout, and he looks over just in time to see Katsuki roughhousing with a group of boys his age in the Bakugou’s own pool, laughing happily.

Izuku feels guilty all over again, tears burning in his eyes as he finally lets the reality of his day catch up to him.

He buries his face in his arms, letting himself finally cry.

TBC

“Hi, new neighbor!” Izuku hears, lifting his head up from where he’s gardening on the front lawn.

It’s Katsuki’s mom - Mitsuki, his mind supplies - waving at him from her own yard.

Izuku’s stomach turns guiltily, still feeling terrible about his attraction to her son.

“Hi!” Izuku calls sunnily. “Mitsuki, right?”

“Mhmm,” Mitsuki hums, grinning. “I know - you’re Izuku. My son told me!”

Izuku grimaces inwardly, but his smile never wavers. “Katsuki’s such a sweetheart! Thank him for the Katsudon, please!”

Mitsuki laughs. “Can’t wait to watch him scowl and pretend he’s not blushing.”

Izuku’s stomach flutters, picturing Katsuki’s blushing face, his cheeks red and his eyes glossy with embarrassment.

“Hey, so,” Mitsuki continues. “Why don’t you and your husband come over for dinner tomorrow night? We’d love to meet you both!”

Izuku swallows. “Oh, we’d love to! I’ll make desert, if that’s okay?”

-

Ronin leaves for another last-second ‘business trip’ the following morning, so when Izuku knocks on the Bakugou’s door that night, he’s alone.

“Izuku,” Mitsuki greets warmly, pulling him in for a hug.

Izuku squeaks, wrapping his free arm around her as he balances desert in the other hand.

“Your husband couldn’t make it?” The blond woman asks, ushering him inside.

“He had to leave for, um, business,” Izuku says, keeping his tone light.

/Half of his ‘business trips’ are most likely just him staying at some extravagant hotel and fucking omegas even younger than me. And hey, I found a pair of panties in his dirty laundry, so he’s definitely cheating on me!/ - is what Izuku wishes he could say.

“I heard he’s some type of CEO, no?” Mitsuki asks, the two of them walking into the kitchen where the delicious smell of cooking food is filling the air. “Not to be a gossip, but Mrs. Raiko down the street told me.”

“Yeah, of Muraoka Technologies,” Izuku says, wishing the topic would change. “I’m so proud of him!”

The fake words leave his mouth feeling sour, but as always, the show must go on.

Masaru arrives a few minutes later, the man soft-spoken and kind when he introduces himself to Izuku before taking over the cooking for his wife.

That must be nice, Izuku thinks sadly.

“Katsuki!” Mitsuki calls upstairs. “Dinner! And dress decent, we have a guest! None of that tank top and boxers bullshit!”

Izuku hears an annoyed groan in response, and just a minute later Katsuki is walking down the stairs dressed in soft gray sweats and a black tank top.

“Didn’t I say to dress decent?” Mitsuki snaps, but her tone is playful. “What’s our new neighbor gonna think?”

Katsuki looks up quickly with a frown, his eyes widening a bit when they land on Izuku, but nothing else gives away his thoughts.

Izuku gives him a small wave, smiling, pointedly ignoring the way his body floods with heat.

“Deku,” Katsuki greets, and Izuku squawks.

“Hey!” He whines petulantly, jutting his button lip out.

“You gave me a shitty nickname, so,” Katsuki sneers. “Payback’s a bitch.”

“Language,” Mitsuki chastises, and Izuku can tell she says that word at /least/ twenty times a day. “Little shit. I apologize for his behavior, Izuku. Damn teenagers!”

“Oh, it’s fine!” Izuku giggles. “Kacchan’s just mad that I’m better at nicknames than him.”

“Kacchan!” Mitsuki chortles. “Oh my god, Masaru, look at him blush!”

“Shut up!” Katsuki growls, his face bright red.

Dinner is amazing, and Izuku lets himself relax for the first time in days, Ronin-free and safe with new friends.

His cheeks hurt from laughing so much, mostly at Katsuki’s grumpiness and Mitsuki’s antics.

Mitsuki is currently chatting their ear off and Izuku listens happily, digging into desert - he brought a homemade chiffon cake, and he preens happily when the dish is quickly emptied.

His eyes wander over to Katsuki as he listens, startling slightly when he sees those sharp red eyes already locked onto him.

Katsuki doesn’t waver, and Izuku feels himself getting hot all over at the heated gaze.

/He’s a teenager, Izuku/, he tells himself. /You’re an adult/.

Katsuki brings his fork to his mouth, and Izuku swallows when the younger flicks his tongue out against a small dollop of cream, repeating the motion in rapid succession, like he’s flicking his tongue against -

Izuku’s mouth falls open, his thighs pressing together uncomfortably.

Katsuki’s eyes are hooded, glued on Izuku, and the alpha wraps his lips around the tiny nub of cream and /sucks/.

“- right, Izuku?” Mitsuki says, snapping Izuku out of his haze.

“I-I’m sorry,” Izuku squeaks. “What was that?”

“I was just telling Masaru about your fancy husband,” Mitsuki teases. “I don’t think I’ve seen that man come home without a exorbitant Shouji suit - we’re in the industry, you know!”

“Oh, yeah,” Izuku says, back to reality. His husband. Right. “He’s, um, always had a taste for the finer things in life.”

“I can see that!” Mitsuki laughs. “Beautiful, young thing like you.”

She says the /young/ with a roll of her tongue, and Izuku knows she’s referencing their nineteen year age gap, and he shuffles his feet uncomfortably.

The conversation flows back to a lighter topic pretty quickly, and Izuku learns more about the fashion industry than he thought he’d ever know.

He also learns about Katsuki’s quirk and hero aspirations, and how he’s taking part in the UA entrance exams next month.

Izuku feels /good/ for the first time in a while, enjoying the refreshing company, laughing happily when Mitsuki breaks out the wine.

He ends up staying until almost midnight, reluctant when he finally has to go.

He falls sleep feeling lighter than he has in a long time.

(Cw: dom*stic abuse, pls be cautious)

Over the next few days, Izuku finds himself spending as much time as he can with the Bakugous - they make him feel less alone. Safe.

They even invite him to Katsuki’s baseball game, and they all go out for dinner and ice cream afterwards.

But all good things must come to an end, and when Ronin arrives home on Wednesday night, pulling himself out of his fancy sports car, Izuku takes in a shaky, nervous breath.

He made sure dinner is ready this time, getting on his hands and knees and scrubbing the floors and counters meticulously.

His husband doesn’t say a word when he enters the house, but the air immediately becomes tense, Izuku’s belly toiling with anxiety.

Izuku keeps his mouth shut, more than happy to exchange no words with the alpha until they go to bed.

Until Ronin ruins that, too - as always.

The man settles into his recliner after dinner, turning on the TV while Izuku hesitantly hovers in the doorway.

“Grab me a beer, sweetheart,” Ronin says, voice neutral.

Izuku nods, popping the fridge open and pulling out the last beer, breathing a sigh of relief when he realizes there isn’t enough for Ronin to get drunk.

Drunk Ronin is even crueler than sober Ronin, if that’s possible.

“It’s the last one,” Izuku says quietly, twisting the cap off and handing the bottle to his husband.

Ronin doesn’t move for a moment, and the room becomes eerily silent.

The TV drones on in the background, but Ronin’s face is still as stone, his mouth finally twisting into an angry frown.

“And you didn’t fucking buy me more?” Ronin shouts shortly, loud enough to shock Izuku’s ears.

The omega jumps, hot terror filling his chest.

I - I,” Izuku stammers. “Y-you didn’t tell me to get you more, -“

“Are you a fucking idiot, Izuku?” Ronin interrupts, and the omega cowers when the man slams the bottle of beer into the wall, the glass shattering on impact.

“Please stop,” Izuku whimpers, and when Ronin stands and pushes him back against the wall, he smells it - the man was already drunk before he got home. Whisky breath.

“Dumb whore,” Ronin slurs. “Could’ve looked in the fridge one goddamn time and seen that I needed beer.”

“I’m sorry,” Izuku cries, feeling pathetic, because he can’t even defend himself. He’s quirkless, and even though Ronin’s quirk is practically useless, the man is twice his size - what can Izuku do, really?

“I work all fucking day, pay all the fucking bills, and you do fucking nothing,” Ronin yells, and Izuku whines in distress at how loud he’s getting. “Can’t cook or clean for shit, can’t make sure I have fucking beer in the fridge. Can’t even get fucking pregnant.”

The alpha gives him one last shove against the wall, walking out of the living room with a scream of “fuck!”, and Izuku’s legs give out as he slides to the floor with a wet sob.

He tries to hold it in, he really does, but he’s a blubbering mess before he knows it.

He sobs on the floor, pulling out his phone and shakily typing a text out to his mom. He wants to stand up and scurry to the guest bedroom, lock the door behind him and hide away for the night, but his legs aren’t working.

Instead, he continues crying, unable to hold in his hiccups and stuttery breaths.

Ronin is still pacing, cursing loudly as he knocks things over around the house, before returning to the room with an ugly, angry look on his face.

“And now /I’m/ the fucking bad guy,” the alpha shouts, voice shaking the walls as he steadily rises in volume. “/I’m/ the bad guy, but you’re the stupid bitch who can’t even take care of my goddamn house.”

Hot tears of fear and shame stream down Izuku’s cheeks, terrified of the man in front of him and embarrassed of the Bakugous hearing and thinking less of him.

“I-I’m g-going to s-stay with my m-mom,” Izuku blubbers.

Ronin laughs with his chest. “You told your mom, huh? Now I’m gonna get a fucking text about what a piece of shit I am, hm? About how you’re too good for me, even though I make every bit of money that comes into this house, and you’re a good-for-nothing, lazy slut.”

“Because y-you won’t let me get a job!” Izuku snaps back, tears still hot.

“Your /job/,” Ronin grunts, kneeling down in front of Izuku. “Is to fucking give me an alpha kid or two. That’s it. That’s all you’re useful for, and you can’t even do that. Cunt.”

Something in Izuku snaps. He’s still sobbing, shaking on the floor, but his eyes harden in adrenaline-fueled determination.

He spits in Ronin’s face, glaring at the alpha that he was foolish and naive enough to marry.

The world seems to slow down for a moment, Ronin’s already irate face turning downright spiteful, and the alpha roars in anger and grabs for Izuku, who’s already scrambling behind the couch.

/What the fuck did I just do?/ Izuku thinks.

“You need to learn your goddamn place,” Ronin yells, and Izuku braces for whatever comes next - a punch, a slap, more angry words.

Instead, there’s a pounding at the front door, hard enough to shake the wood from its hinges.

One solid kick has the door flying open, splintering and broken, revealing a downright pissed-off Katsuki.

“Touch him one more time,” Katsuki threatens. “And I’ll show you what it feels like to have your torso wrapped around your fucking head.”

TBC

Ronin lets out a short, drunken laugh. “Who the fuck’s this kid?”

Katsuki doesn’t grace him with a response, just stalks forward, shoving Ronin face-first into the wooden floor before lifting Izuku up into his arms, the omega wrapping his legs around the teen’s waist.

It’s obvious that Katsuki has been working out, preparing for the UA entrance exams, and Izuku hiccups when a thick arm wraps around him protectively.

“You’re sleeping in our guest room tonight,” Katsuki says decisively. “But I need to take out the trash first, okay?”

Izuku is hiding his face in Katsuki’s neck, but he can tell that they’re walking outside, onto the deck.

“Stay here,” Katsuki murmurs, wrapping the plush blanket he’d snatched from the couch over the omega’s shoulders. “I’ll be right back, okay, beautiful?”

“No,” Izuku says, still trembling. “K-Kacchan, you’re fifteen, this isn’t your responsibility, please g-go get your parents -,”

“You think I’m not capable of putting your fuckhead of a husband five feet under?” Katsuki snorts. “Consider my ego damaged.”

“How’d you, um, know?” Izuku asks quietly.

“Was laying in my bed and heard him screaming,” Katsuki murmurs angrily. “The thought of him hurting you -,”

The alpha trails off, wiping his hand over his mouth.

“Did he hurt you?” Katsuki asks, voice low. Dangerous.

Izuku shakes his head softly. “No. Not physically.”

“Did he touch you at all?” Katsuki continues, looking like he’s one second away from losing his cool.

Izuku bites his lip. “No,” he lies. “He didn’t touch me.”

“Izuku,” Katsuki says gently, like he doesn’t believe him. “I’ll be right back, okay?”

“Kacchan, wait -,” Izuku says, voice shaking. “Please don’t. Let’s just go, okay?”

“I won’t do anything,” Katsuki says, and Izuku can hear the insincerity dripping from his words.

But the blond is already closing the door behind him as he enters the house, giving Izuku a gentle smile over his shoulder, eyes soft and fond.

Izuku shivers, wrapping the blanket around his body tighter as he waits.

-

Ronin screams in pain, clutching his freshly burnt forearm pathetically.

“That’s just a preview,” Katsuki says, eerily calm. “Of what will happen to your entire fucking body if I ever hear you yell at him like that again.”

Ronin spits near his feet, face still flushed with alcohol. “Look at you being the white knight, kid.”

Katsuki buries his fingers in the man’s thinning hair, yanking his head back roughly.

“Nah,” Katsuki growls. “This is me being a halfway decent human being. Try it some time.”

Ronin groans in pain, but he still manages to let out a short bark of laughter.

“You want him, huh?” Ronin taunts. “You wanna fuck him?”

Katsuki flushes pink despite the position he’s in, kneeing the older man into the floor.

“You do!” Ronin chuckles. “He’d probably let you, too, the little slut. He’d let a kid use his cunt, I’m sure.”

Katsuki’s hands crackle dangerously close to Ronin’s face, leaving the hair there singed.

The man shrieks in pain, trying to twist his head away from the heat, but Katsuki’s fist in his hair is firm.

“I could fuck him better than you ever have,” Katsuki sneers. “And I’m a third your fuckin’ age.”

Katsuki lets go of the man’s hair, kicking him back into the floor for good measure, hearing a satisfying crunch when his nose slams into the wood.

“Here’s what’s gonna happen,” the blond says, no room for argument. “You’re gonna leave, and go stay somewhere else for a while, hm? And if you don’t, I‘ll burn every square inch of your body ‘til your own mother wouldn’t recognize ya.”

Katsuki can see the pathetic, tiny wheels turning in Ronin’s head, weighing his options.

“And if anyone asks?” Katsuki continues. “I’ll say you threw the first punch.”

Ronin swallows, Katsuki never once breaking his hateful stare.

Ronin knows when to admit defeat - Katsuki is a bit smaller and leaner than him, but the younger has a quirk that could deal some serious long-term damage.

And so, the man stands with a grimace of pain, spitting out a wad of blood, holding his most-likely broken nose.

He leaves without a word, grabbing his keys from the hanger and angrily storming out of the house.

Katsuki watches him go, eyes intense, before deflating with a sigh and walking out back to where Izuku is waiting for him.

“He’s gone for a bit,” Katsuki says softly, cupping Izuku’s cheek.

Izuku smiles, eyes still watery. “Thank you, Kacchan.”

Katsuki’s thumb strokes along his face, tender and sweet, and he nearly combusts when the omega leans into his touch.

“Can I carry you again?” Katsuki asks shyly.

“I’d appreciate it,” Izuku giggles, wiping his eyes. “I don’t think my legs want to work yet.”

Katsuki gets one arm under Izuku’s ass, blushing at the contact, and the other wraps around his body.

His parents are asleep, but they won’t mind Izuku staying over - especially when Katsuki tells them what happened.

The Bakugou’s guest room is homey and smells amazing, and Izuku immediately cuddles into the sheets when Katsuki sets him on the bed.

“Get some rest,” Katsuki murmurs, combing his fingers through Izuku’s hair.

Izuku is quiet for a moment, and Katsuki almost thinks he fell asleep, and the blond stands to leave.

“Thank you, Kacchan,” Izuku whispers.

“Don’t get sappy on me,” Katsuki grunts, but his inner alpha buzzes at the praise.

“My little hero,” Izuku purrs, clearly drifting off to sleep.

Katsuki sputters, but he doesn’t say another word, standing there for a few minutes until Izuku is gently snoring.

TBC

The next day, it takes nearly an hour for Izuku to talk his mom out of hunting Ronin down and skinning him alive, and he guiltily looks at the floor when she starts to cry.

“Please, honey,” she chokes out. “Please, just come home.”

“Mom,” he sighs. “You know I can’t.”

There’s a static-y silence before Inko lets out a shaky breath. “I don’t care about that. Just come /home/.”

“He pays your medical bills, mom,” Izuku whispers, shame burning hot.

“I’ll find another way,” Inko presses. “We’ll figure something out, baby.”

Izuku shakes his head like she can see. “You need dialysis, mom. You won’t -,”

/You won’t survive without it. The doctors said so./

“He’s not worth this,” Inko sobs. “Please.”

Izuku sniffs, looking down at his shaking hands. He’s pathetic. Simply pathetic. Standing here, refusing to leave the man who threatens him, calls him names, treats him like dirt on his shoe.

All because he has money. Money that keeps his mom /alive/. Money that feeds Izuku and gives him a roof over his head, because he’s twenty-five with no degree or experience, and only one job as a Barista under his belt - the very one that Ronin had swept him away from.

He’s been reduced to nothing, a puppet completely controlled by his husband.

“I won’t be responsible for you dying, mom,” Izuku finally says. “I’m sorry. I’m not leaving him. I love you.”

He hangs up, promising himself that he’ll call her later tonight to talk things over once she’s calmed down.

There’s a soft knock at the door.

“All good in there?” Mitsuki calls.

Izuku lifts his head, clearing his throat. “All good!”

He’s still at the Bakugou’s, Mitsuki insisting that he stay once Katsuki told her what happened.

She’d been dialing the police when Izuku /begged/ her not to, and she’d only stopped when Izuku started to cry.

“Dinner’s almost ready,” Mitsuki continues, her voice so gentle and soft and /caring/, things Izuku hasn’t experienced since he moved away from his mom.

“I’ll be down in a bit,” Izuku says, stretching. He’s been in bed practically all day. “Just gonna take a quick shower.”

He wobbles a bit when he stands, feeling like his entire sense of balance is off as he drags himself to the bathroom.

When he undresses, he cringes at the forming bruises on his shoulders and upper back from where Ronin slammed him into the wall.

The skin is tender to the touch, and he whimpers at the ache when he lifts his shirt above his head.

The hot water feels like it’s washing away his troubles, his eyes fluttering closed as he scrubs his body and hair clean of Ronin’s touch.

Katsuki immediately darts out of his chair and helps Izuku to the table when the omega hobbles into the dining room, pulling his chair out and helping him sit.

“I’m not broken, Kacchan,” Izuku teases, but he flashes him a small, grateful grin.

“You don’t need to be broken to get help,” Katsuki says, and Izuku’s mouth goes dry.

-

A few days go by, and Izuku can’t seem to get rid of the constant dread filling his belly. He checks his phone every five seconds, glancing outside to their driveway almost constantly.

Because Ronin always come back. It may take a week, a month, longer even - but the man will come back for what’s ‘his’.

Izuku just has to sit and wait, and try to keep his mind off of things.

The Bakugous have been letting Izuku use their second car, and the omega is basking in the newfound, temporary freedom. He drives to the store just to walk around, goes to the beach to bask in the sun, picks Katsuki up from school.

It’s perfect.

If there’s one thing keeping Izuku sane, it’s Katsuki.

“Wait,” Izuku says the first time he steps foot in the blond’s room. “Is that a platinum Silver Age All Might from Hero Con 20XX?”

Katsuki’s eyes nearly bulge out of his head. “How the fuck do you know that?”

“Kacchan!” Izuku scoffs playfully. “You’re in the presence of All Might’s number one fan.”

Katsuki looks at him in awe, eyes shining with admiration, and Izuku kind of hates the way it makes his chest flutter.

-

Izuku moves back to his own house after about a week, dragging his back of clothes after him as he walks through the threshold.

Mitsuki had been adamant that he stay, and as much as Izuku loves being there, he feels like he’s overstayed his welcome.

Katsuki is pissed at first, but he breaks after just a day, knocking on Izuku’s (repaired) front door and shyly holding up an All Might 4: All Might does Australia CD.

Izuku makes popcorn, the two of them snuggling under blankets on the couch.

“This part is so cringe,” Katsuki groans halfway into the movie. “Why’d they make the kangaroo talk?”

“He’s not a kangaroo, Kacchan!” Izuku says matter-of-factly. “He’s a guy with a kangaroo quirk!”

“Why the fuck does he look like a whole ass kangaroo?” Katsuki complains, tossing a handful of popcorn into his mouth. “Miruko has a rabbit quirk and she’s clearly fucking human.”

Izuku pauses, humming. That part somehow slipped his mind.

“Okay,” Izuku concedes. “You may have a point.”

“I’m always right, Deku,” Katsuki gloats, and the way the distant kitchen light catches his eyes has Izuku’s breath stuttering.

Katsuki laughs at his dazed expression, throwing a piece of popcorn at his head.

Izuku shakes his head, giggling, and pops the piece into his mouth. When he looks away, he misses the way Katsuki peers at him out of the corner of his eye, his own heart skipping a beat.

TBC

Katsuki gets all A’s on his final exams for the year, and Izuku takes him out to his favorite shitty sushi stand in celebration, which the omega absolutely hates, but Katsuki seems to love, for some inexplicable reason.

Now that he’s out of school for a few weeks, Katsuki uses his power of persuasion to convince Izuku to drive to the countryside and hike questionable trails with him, and if Izuku ends up being carried on Katsuki’s back more than a few times, it’s no one’s business but his own.

On one particularly grueling hike up a small mountain the locals call Blueberry Hill, they’re chased by a pack of wild turkeys and Katsuki has to blast them away from the danger, wrapping a strong arm around Izuku’s waist and setting off an explosion with the other.

It’s well worth it when they end up reaching the peak and looking out over the crystal clear water of a small tarn in the middle of the mountains.

They catch their breaths and laugh hysterically, shrieking when the turkeys catch up to them.

Katsuki’s a serious kid, and Izuku knows he’s taking the whole ‘getting into UA’ thing very seriously - he’s up at 5AM jogging most days, lifting weights at the community gym for hours on end.

Izuku can see his progress - the ways his shoulders broaden, the way his biceps begin to bulge through his tighter shirts, the way his abs become more defined and tight.

And Izuku just cheers him on and keeps his disgusting thoughts to himself, becuase Katsuki is a /kid/, and Izuku is beginning to see him as a little brother of sorts.

In a place where he feels like the loneliest person in the world, it’s nice to have a friend - even if the age gap is a bit problematic.

Izuku has been practicing chasing away any thoughts about Katsuki that pop into his head, and it’s been - fine.

Because even if Katsuki has a schoolkid crush on him, it’s Izuku’s responsibility as the adult to shut it down.

“Who’s Katsuki?” Inko asks over the phone one day, the sizzling of her cooking dinner a nice background noise.

“Oh, um,” Izuku says. “I told you about the Bakugous - Katsuki’s their, um, son.”

Inko is quiet for a moment. “I’m glad you found a friend, baby.”

She doesn’t ask his age, which Izuku is eternally grateful for.

-

A couple of weeks pass with no word from Ronin, and Izuku begins to let his guard down just a bit.

“Pistachio, seriously?” Katsuki asks, voice dripping with judgement as Izuku happily takes the ice cream cone he’s handed.

“It’s /so/ good,” Izuku defends, and Katsuki follows him out into the sunshine after ordering his own double scoop of cookies and cream.

“Yeah, if you’re eighty,” Katsuki gripes, and Izuku just giggles and loops their free arms together as they walk to the beach.

They settle down on towels, and Izuku props one of the beach umbrellas over himself, laying in the shade, which Katsuki judges too.

“You’re definitely an old man trapped in a twenty-five year old’s body,” Katsuki says with fake disgust.

Izuku just sticks his tongue out at him before wrapping it around the tip of the ice cream cone.

It’s such a hot day, the seabirds squawking above them, eyeing their food hungrily.

Couples with their kids play in the water, older folks laying in the sun and listening to classic rock music.

Izuku gets lost in people-watching, wrapping his lips around the ice cream.

He’s a messy eater, and he can feel the sticky sweetness dripping down the side of his mouth.

He grabs for the corner of his towel to wipe his mouth, glancing over at Katsuki.

He nearly jumps when he sees the boy staring at him intently, mouth agape as he hones in on the liquid dripping down his skin.

The blond’s own ice cream is melting down his hand, oozing to the sand below.

“Kacchan?” Izuku calls, and the alpha seems to snap out of whatever trance he was in.

“You’re fuckin’ messy,” Katsuki yells, and his face burns bright red - Izuku doesn’t think it’s from the sun.

Izuku just points to the ice cream dripping down the boy’s hand, which earns a deeper blush.

Izuku throws his head back in laughter, and the corners of Katsuki’s lips twitch until he’s laughing, too.

-

It happens while Katsuki and Izuku are hanging out, of course - they’ve spent most of the summer together, a whole month of Ronin-free bliss passing in the blink of an eye.

Katsuki’s phone dings, and the blond pulls it out of his pocket lazily.

His eyes widen, reading through whatever message he received, and then he’s jumping out of his seat and shouting in glee.

“I got in,” he yells, grinning wide. “I fucking got in!”

Izuku is immediately smiling, too, pulling Katsuki into a big hug.

“Kacchan!” The omega cheers. “Oh my god, I’m so proud of you!”

Katsuki laughs, wrapping his arms around Izuku’s back snugly, leaning down and nuzzling his cheek into the smaller’s shoulder where the omega’s arms are thrown around his neck.

“Fuck,” Katsuki breathes. “I’m going to UA, Izu.”

“You’ll be the best hero,” Izuku sighs, heart twinging a bit when he thinks of his own childhood hero dreams. “Number one.”

Katsuki smirks, pulling back with his arms still around Izuku. Their faces are much too close, Izuku thinks, and his heart begins to pound wildly in his chest.

Katsuki’s arms hold him tight, and Izuku moves his own hands down to rest on the boy’s shoulders.

The omega’s brain goes offline when Katsuki’s throat flexes with a nervous swallow, and there are suddenly soft lips on his own.

Izuku’s eyes widen, and he immediately shoves at Katsuki’s chest, their lips breaking apart as quickly as they came together.

TBC

“What are you - ?” Izuku yells, immediately moving away from Katsuki and putting some much needed distance between their bodies.

He hates the way Katsuki’s face falls.

“Izuku, I -,” Katsuki starts.

“You’re fifteen, Kacchan!” Izuku cries out, pulling at his own hair in horror. “Oh my god, you’re a kid, and I just kissed you -,”

“/I/ kissed /you/, and I’m not a kid!” Katsuki says firmly. “I /want/ this, Izu, it doesn’t matter that I’m fifteen -,”

“Yes it does!” Izuku shouts. “D-do you not understand how much trouble I could get in, oh my god -,”

“No one will know!” Katsuki says, raising his voice a bit to match Izuku’s. “I want you so bad, Izu, please. And I know you want me back.”

“It doesn’t matter what I want!” Izuku nearly screams, his eyes are glossy with hot tears. “You’re - I’m an adult, Kacchan!”

“It doesn’t matter,” Katsuki tries. “We won’t tell anyone we’re together ‘til I’m an adult.”

“We’re not together!” Izuku sobs, and oh god, he’s definitely crying now. Shit. “We never will be! I’m /married/, and you’re gonna go to UA and forget that any of this happened, and you’ll be disgusted when you think back to kissing me. You’ll be disgusted, Kacchan.”

“Why the fuck would I be disgusted?” Katsuki asks, looking genuinely bewildered. “You’re the only person I’ve ever wanted, Izuku. God, you do things to me that I’ve never felt, and -,”

“You’ll realize how wrong this is in a few years,” Izuku interrupts. “Trust me, Kacchan. Please. It might seem like you want me now, but /please/. You’ll meet someone your own age, someone with a powerful quirk who can be your hero partner. And you’ll forget all about me, okay?”

“I don’t want that!” Katsuki grunts in frustration. “I want /you/, Izuku! I l-like you a lot!”

Izuku stands there, tears streaming down his face, guilt overtaking his entire body when he looks at Katsuki’s blushing face as the young alpha proclaims his crush.

Oh god, he’s so /young/,
blushing and stammering as he confesses, and Izuku has never felt like a worse person.

“I won’t be ‘traumatized’ or whatever shit you’re thinking in your overanalyzing ass head right now,” the blond continues.

“Kacchan,” Izuku sighs shakily. “When you’re my age, you’ll realize how /wrong/ it would be for me to be with you. You’re fifteen. Please, I can’t -,”

His words trail off when Katsuki moves closer again, cupping the omega’s cheek in his big palm.

“Tell me you don’t want me,” Katsuki demands, peering into his eyes like he can see his soul if he looks hard enough. “Stand there and tell me.”

Izuku’s lips tremble, a small whine leaving his throat instead of the words that should.

When Katsuki leans in again, Izuku doesn’t fight it, his arms snaking up around Katsuki’s neck as their lips press together.

Katsuki’s own big arms wrap around his waist, pulling him against his solid body.

It’s clear that Katsuki is inexperienced - and oh fuck, this is probably his first kiss. Izuku pushes that thought away as quickly as it came, not wanting to think about the implications.

The omega guides the kiss, tilting his head when Katsuki’s tongue swipes at his bottom lip.

Katsuki makes up for his lack of experience with pure eagerness, licking into Izuku’s mouth and letting the smaller train him with his own tongue, the kiss quickly turning downright filthy.

“Mmn,” Izuku moans into it, whining when Katsuki’s hands move down to grope his ass, hands flexing on his cheeks possessively.

Lips never parting, they fall back onto the couch, Izuku settling on Katsuki’s lap as the kiss deepens.

The omega’s lips are tingling, sparks that he’s never felt with Ronin dancing on his skin, and it’s clear that Katsuki feels the same way - a deep blush on his face, his eyes closed in bliss.

Izuku’s own hooded eyes wander a bit, not wanting to get lost in /Katsuki/, and they land on a portrait of him and Ronin hanging above the fireplace - Ronin standing behind him, hands on his shoulders as Izuku grins sunnily into the camera.

And reality falls back into place.

Izuku breaks the kiss with a gasp, hating himself when Katsuki immediately chases his lips.

Izuku scrambles off of his lap, wrapping his arms around himself as he shakes with guilt, fear, and misplaced arousal.

“Please leave,” Izuku says quietly, backing away when Katsuki stands to move closer.

“What?” Katsuki asks, incredulous. “Izuku -,”

“Leave!” Izuku screams.

“You - we just kissed!” Katsuki yells, and fuck, his eyes are getting wet. Izuku can see the wetness catching the light.

“I’m sorry!” Izuku says, his whole body shaking with anxious shivers. “I’m so sorry, Kacchan!”

“You have nothing to be sorry for!” Katsuki shouts, wiping away his angry tears. “Please - I just want you. Please.”

“Leave,” Izuku repeats, quieter this time. “Leave and forget about me, Kacchan. And please don’t hate me when you grow up and realize how /wrong/ this is.”

“The only thing /wrong/ here is that you can’t see that I’m perfectly fine!” Katsuki groans.

“I asked you to leave,” Izuku says. “This isn’t just about you, Kacchan! My life is /over/ if anyone finds out about this! I’m /cheating/, and you’re /underaged/!”

“I wouldn’t tell anyone!” Katsuki growls, clearly not understanding how dire this situation is.

“Think about what you just said!” Izuku shouts. “You won’t tell anyone, because why? Because it’s fucked up, and I’d go to jail!”

“No one will know,” Katsuki repeats. “And if anyone finds out, I’ll tell them I kissed you first.”

“It doesn’t matter, oh my god!” Izuku says, voice getting steadily higher with anxiety. “I’m an adult! I’d be responsible. Do you not understand?! Leave!”

“Goddamnit,” Katsuki tries. “Please.”

“Leave, or I’ll call the cops on myself right now,” Izuku threatens. “Please, Kacchan. Leave.”

Katsuki stands there for a moment, his expression going through approximately ten different emotions before he sighs.

The blond closes the door gently behind him, and leaves.

TBC

The next time Izuku sees Katsuki, the blond is in the Bakugou’s backyard, practicing his quirk against dummys strategically placed around the lawn. He looks solemn, sending one dummy flying with a swinging kick.

Izuku lays low, tipping his sun hat over his forehead as he reads his book on the deck.

It’s sunny out, birds chirping carelessly as Izuku internally panics. He’s still disgusted with himself, two days after the kiss.

He still tastes Katsuki on his tongue, all minty toothpaste and smoky alpha.

When Mitsuki had asked him to come over for dinner last night, he’d nearly sobbed and confessed before he turned her town with a simple ‘sorry, I’m busy!’ And a plastered on grin.

He’s been home bound, too guilty to use the Bakugou’s car after he’d let their fifteen year old son shove his tongue down his throat, grope his ass, pull him into his lap.

Izuku feels like he’s in a trance as he watches Katsuki move around the yard, setting off explosion after explosion, clearly letting out some type of frustration.

Izuku bites his lip, hoping that the blond understands his point of view when he’s a bit older.

He hopes the blond doesn’t hate him once he figures out how disgusting it was for Izuku to allow him to kiss him like that.

Izuku sighs, closing his book with a snap and wrapping his swimsuit coverup around himself.

He slides open the back door, sparing another glance back at the blond and gulping when he sees red eyes locked onto his own.

Katsuki’s lips are twisted into a frown, and Izuku’s heart cracks a bit when he sees the /hurt/ in his eyes.

Izuku wishes he could do something, anything, to make this situation better. He wishes he could make Katsuki see that he doesn’t really want Izuku, he just has a juvenile crush on someone out of his reach - someone much too old for him.

Izuku gives him a soft, guilty smile back, before gently sliding the door closed behind him.

-

Izuku decides to go for a walk, which turns into a two hour trek around the neighborhood, earphones in as he listens to melancholic music.

He can’t seem to get rid of the guilt over Katsuki, nor the fear of Ronin returning any day now. His husband will come back, scream at him for what happened, and everything will go back to how it was - Izuku trapped in an unhappy marriage, unable to leave.

He can’t risk his mother’s health. He knows Ronin hadn’t stopped paying her medical bills the night he left - he’s checked the statements. All paid.

It just makes it worse, really. Ronin will guilt trip him, call him a leech, and Izuku will have to grovel and spread his legs in some kind of sick ‘thank you’.

Izuku hates it.

It’s dark when he arrives home, and he nearly trips on something laying on his front porch.

It’s a bouquet of flowers, wrapped in gold paper with a little note tucked neatly inside.

They’re crazy daisies - and he nearly whines when he remembers how he’d ranted to Kacchan about how he’d prefer receiving a bouquet of the wildly colored flowers than any of the fancier types.

He plops the flowers in a vase of water, unwrapping the note with shaky hands.

/Izuku,

You’re too beautiful, kind, caring, and perfect for me to just stop trying for.

I’m sorry, but I’ll do everything in my power to have you forgive me and understand how much I like you.

-Kacchan/

It’s short and to the point, and Izuku feels tears welling up in his eyes. Kacchan thinks he’s perfect?

He shakes his head, contemplating throwing the note in the trash before he sighs and folds it up, tucking it into the little box of personal things he keeps in the cleaning closet.

God, he’s a fucking masochist, isn’t he?

TBC sorry for the shorter update, today has been a day!! 💀

Cw: I did tag this thread underage, but fair warning: underage sex is coming. Feel free to dip! For anyone else, enjoy the fictional fuckery.

Izuku’s resolve is cracking by the day, and he kind of hates it.

He starts coming home to a present every day following his newfound daily walks - on the second day, there’s a box of homemade pistachio fudge, and he nearly moans when he plops a piece in his mouth.

On the third day, it’s a pristine, still-in-the-box silver age All Might figure from twenty years ago, and he /actually/ makes an embarrassing noise this time.

And then - on the he fourth day, it’s Katsuki himself, the blond sitting at his doorstep looking nervous.

“Hey,” Katsuki says, jumping up to greet him. “Hi.”

“Hi, Kacchan,” Izuku says, feeling small as he opens the door and lets them both inside, keeping his eyes trained on the ground with a blush.

“I, um,” Katsuki mutters. “Can we talk? About everything?”

“There’s nothing to talk about,” Izuku sighs. “Kacchan, you’re sweet, and if you were an adult this entire situation would be different, but -,”

“But what?” Katsuki interrupts. “I like you, Izuku, and I think you like me too? Hopefully?”

He looks entirely too innocent, his normally sharp eyes blown wide as he waits for Izuku to confirm.

“I like you, Kacchan,” Izuku murmurs. “And that’s not right. So I think it’s best if we just keep our distance, okay?”

“You didn’t like the gifts?” Katsuki asks in a small voice, and Izuku wants to literally scream at the dejected look on his face.

The omega groans. “I’m /married/, Kacchan! And an adult!”

“You’re married to a fucking dickhead!” Katsuki points out. “You can leave his ass!”

“It’s not that simple,” Izuku argues, wishing he could just make Katsuki /see/ his point of view. “I-I love him. I do.”

The lie feels sour on his tongue.

“No you fucking don’t,” Katsuki groans. “Izuku, he’s a sexist, abusive piece of shit. You don’t love him.”

“He takes care of me,” Izuku breathes out, backing up when Katsuki moves closer.

Katsuki’s hand reaches up to hesitantly brush his fingers along Izuku’s cheek. “/I/ can take care of you.”

“Don’t,” Izuku whimpers, but his words hold no heat, and he doesn’t move when Katsuki leans in.

Their lips brush together, more soft than last time, less desperate and carnal, and Izuku whines into it - the taste of Katsuki, the way he smells. It’s all too much, too good.

Katsuki’s hand on him is too gentle, too loving. Too protective.

They stand there, chastely kissing for what feels like an eternity, and Izuku can’t fight off how /right/ it all feels, even when it’s the most morally wrong thing he’s ever done.

He rests his hands on Katsuki’s strong biceps, feeling the muscles there jump with nerves under his soft touch.

He loves how Katsuki is already bigger, broader than him. In the next few years, he’ll most likely get even larger - muscles growing with hero training.

His hands squeeze rhythmically around the solid muscle, groaning softly when Katsuki’s teeth graze his bottom lip, pulling it back slightly.

“I want you,” Katsuki breathes against his lips. “And you want me. What’s the problem?”

“K-Kacchan,” Izuku whimpers, moaning when big hands slide down his waist to his hips, fingers grazing his ass through the soft leggings he wore on his walk. “W-we can’t do this.”

“Mm,” Katsuki hums, a teasing lilt to his tone. “Looks like we already are.”

Izuku closes his eyes with a whine when Katsuki’s lips descend to his neck, leaving shivers in their wake.

The blond’s tongue peeks out to lick over his skin, right over the unbitten mating gland that Ronin refuses to claim before he’s birthed him a child.

Izuku only feels relief at that fact now, Katsuki’s eager licking and sucking sending heat straight to his core.

“You smell like fucking home,” Katsuki groans, and Izuku agrees so, so much - the young alpha smells like a cozy campfire, roasting marshmallows on a cool night in autumn.

“Kacchan,” is all Izuku can say, voice airy, his eyes fluttering in pleasure.

“I’m gonna take you away from him,” Katsuki promises, pressing kisses to his shoulder and neck between every word. “Gonna take such good care of you. You’re gonna go back to school and become a fucking badass hero tech engineer.”

Izuku giggles, his belly filled with butterflies when Katsuki grins against his skin.

“You just want me to work for you when you’re the number one hero,” Izuku teases, leaning up on his tip-toes to press their lips together again.

“What can I say?” Katsuki murmurs against his lips. “My hot ass wife making me gear? I’d be the luckiest man in the world.”

Izuku turns red at the word ‘wife’, and he buries his face into Katsuki’s generous chest shyly.

“I want that, Kacchan,” Izuku whispers. “So bad.”

“Then I’ll make it happen,” Katsuki soothes, ghosting his fingers along Izuku’s back. “I promise.”

Katsuki’s roaming hands move down to his ass, and Izuku’s emotions are having an all out war between guilt and pure, unadulterated /want/.

“Can I make you feel good?” Katsuki asks, his voice so young and unsure, and Izuku’s heart goes haywire.

“We can’t,” Izuku whispers. “We can’t, Kacchan.”

His voice doesn’t hold as much conviction as it did just a few minutes ago, and the fight in him is being slowly choked out.

He whines when Katsuki presses even closer, and he can feel the young alpha’s erection digging into his thigh.

“You deserve to feel good,” Katsuki whispers against the shell of his ear.

TBC

Katsuki helping him undress feels more intimate than it ever did with Ronin, the drag of fabric leaving goosebumps along his skin.

The blond’s touch is so gentle, so eager, and Izuku’s nerves sing with delight at every point of contact.

They’re in the guest room now, because Izuku isn’t about to do this in the same bed that he’s had to endure monotonous sex with Ronin.

The guest room bed is plush, and he sinks into it when Katsuki lays him down, stripped down to his panties.

“You’re so fucking pretty,” Katsuki says, like he’s angry about it.

The alpha crawls into bed with him, trailing kisses up and down his body like he’s something to be worshipped.

Izuku giggles when Katsuki’s lips brush along his sensitive spots, and the blond focuses his attention there just to be cruel.

“Kacchan,” Izuku breathes when those big hands start toying with his panties, one finger hooking around the fabric to pull them to the side.

Katsuki looks awestruck as Izuku’s chubby pussy is revealed, his throat moving with a nervous swallow.

“You don’t have to do anything you don’t want to,” Izuku says, suddenly self-conscious when Katsuki continues to stare at his slick folds.

Katsuki doesn’t answer, just reaches his hands out and uses his thumbs to splay open Izuku’s hole.

“Kacchan!” Izuku squeaks, his eyes nearly rolling back into his head when Katsuki leans in, a broad, eager tongue licking between the omega’s pussy lips.

“Oh my g-god,” Izuku moans, small hands immediately burying into Katsuki’s thick hair. “K-kacchan!”

Katsuki just groans at the way Izuku tugs at his hair as he wraps his lips around that sensitive clit.

Izuku’s eyes roll back in pleasure, because he’s never been eaten out before. Sex with Ronin is entirely one-sided, and he didn’t know it could feel like /this/.

Katsuki clearly did his research, and Izuku’s thighs automatically clamp around the young alpha’s head when he begins to alternate between sucking at his clit and rapidly flicking the bundle of nerves with his tongue.

It’s wet and messy, and Katsuki’s chin and Izuku’s thighs are quickly covered in slick and spit, not that the blond seems to kind - he just continues slurping and moving his head back and forth like he can’t get enough.

Izuku lets himself relax, hands still buried loosely in Katsuki’s hair, his body going boneless against the soft sheets.

His hips are grinding against Katsuki’s face on their own - the alpha takes it in stride, pressing his tongue to a point and sliding it into his sweet hole.

“Oh,” Izuku moans, mouth falling open and eyes fluttering closed in ecstasy. “That’s it, K-Kacchan.”

Katsuki hums at the praise, fucking him out on his tongue with languid licks.

“So good,” Izuku whimpers, a blissful grin on his face. “Such a good boy, Kacchan.”

His words seem to make Katsuki more eager, the blond pressing two thick fingers into his hole as he withdraws his tongue and focuses it back on his clit, circling it with the tip.

“Mmn,” Izuku purrs, pussy clenching around the finger slowly thrusting in and out, in and out. “You can add another.”

Katsuki eagerly presses another in, and Izuku keens at the stretch of three fingers filling him up.

The alpha already seems to know his body better than Izuku himself, quickly learning what makes him feel good, and Izuku can feel the tight heat of arousal in his abdomen, ready to burst.

Katsuki is playing his clit like he /knows/ exactly what Izuku needs, soft lips wrapping around the nub as he thrusts his fingers into his wet pussy like a machine, slowly picking up the pace until he’s /fucking/ them in and out.

Izuku’s hole clenches and unclenches around the fingers rhythmically, Katsuki’s hand soaked with slick.

“You’re gonna make me cum,” Izuku whines, untangling his hands from Katsuki’s hair and reaching up to toy with his own nipples.

His chest has always been sensitive, and he teases and squeezes at the nubs, his face hot and eyes hooded as he peers down at Katsuki working between his legs.

Katsuki just looks happy to be there, cheeks painted with a pretty blush and a serene look on his handsome face.

Katsuki moans into his pussy, sending vibrations that make his nerves tingle with delight.

Izuku’s hips jerk down, grinding on Katsuki’s fingers and lips.

The blond pulls off for a brief moment, panting. “Cum for me, baby. Please. Cum on my face.”

As soon as those lips are on him again, Izuku’s belly seizes with his orgasm, and he moans wantonly at the ceiling, throwing his head back against the pillows as he cums.

His walls try to milk Katsuki’s fingers like they’re his knot, and the alpha moans against his clit at the feeling.

“Ahh-n, f-fuck, Kacchan!” Izuku whimpers at the ceiling, his body shuddering with electric zaps of pleasure.

It’s so good, and he’s never cum like this before in his life - not from his own hands, and certainly not from Ronin.

It feels like it lasts forever, his pussy pulsing in waves as Katsuki’s fingers languidly thrust, lips and tongue coaxing his clit through it.

“Too much,” Izuku whimpers when the orgasm finally begins to become just a dull pleasure in his abdomen.

He’s left there feeling boneless, his legs still twitching, thighs splayed wide open on the sheets.

Katsuki pulls his fingers free with a lewd wet noise, and Izuku bites his lip when the blond immediately buries the hand in his own pants, wrapping the slick-wet hand around his cock.

TBC

Katsuki’s mouth falls open, his eyes hooded with arousal as he jerks himself off, his eyes glued on Izuku’s body the entire time. He strokes slowly, using his free hand to pull his sweats and boxers down, and then it’s Izuku’s turn to gape.

Kacchan’s cock is /huge/, long and thick with heavy balls at the base, and Izuku’s thighs squeeze together with another rush of slick at the sight.

It’s so much bigger than Ronin’s, and Izuku fights down the wave of guilt that comes with the thought.

He’ll have time to feel like a terrible person later - for now, he spreads his legs open on the bed, sliding his fingers through his slick lips as he watches Katsuki’s big hand around his cock.

“Come here,” Izuku purrs, grinning when Katsuki immediately moves forward eagerly, clambering onto the bed, his muscular arms flexing as he crawls over Izuku.

“Is this okay?” Katsuki asks, suddenly acting his age.

“Mhmm,” Izuku says softly, a lust-hazed, dopey grin on his lips. “More than okay.”

Katsuki presses their lips together again, Izuku’s thick thighs loosely wrapping around the blond’s small waist, wanting him impossibly closer.

“I want you inside,” Izuku whispers, nerves alight as Katsuki breaks their kiss and trails his lips down his sensitive neck instead, brushing them over the omega’s mating gland possessively.

The blond looks like a god above him, all muscle and broad shoulders and a stupidly handsome, smirking face.

“Anything you want,” Katsuki says, like a promise, the thick head of his cock nudging between Izuku’s chubby pussy lips, rubbing up and down.

The leaking, red tip teases at his sensitive clit, smearing precum all over the little nub like a mark of ownership.

Izuku moans softly, spreading his legs wider, hips grinding down against the stimulation on their own.

“Put it in,” Izuku whines, feeling his own slick sliding down his thighs and onto the first bed, leaving a wet mess of pheromones and lust.

Katsuki grins like a predator that’s finally caught his prey, the head of his cock catching on Izuku’s hole as he passes over it.

Izuku’s pussy clenches around it hungrily, begging it to push inside, own him.

“Your pussy is so needy,” Katsuki teases, using his big hands to wrench Izuku’s legs apart, the blond staring down at where his thick cock is poised to enter.

“Mine,” Katsuki proclaims, so sure and confident. “No one else’s.”

“Yours,” Izuku parrots, eyes hazed as just the tip of Katsuki’s dick has him feeling like he’s floating in the stars. “Fill me up, a-alpha.”

Katsuki leans down, pressing their lips together softly yet again - before pushing inside slowly, sinking himself into Izuku’s welcoming, warm pussy like it’s home.

The omega’s eyes twitch in pleasure, his mouth falling open in a slutty moan as he’s filled like he needed.

Green hair spills onto the white pillow behind him, a halo of soft curls framing his freckled face that Katsuki can’t seem to take his eyes off of.
