Work Text:
The first thing he’s aware of when he wakes is there’s an ache in his body below the warm blankets, yet a bone deep sense of comfort keeps him content. He cracks his eyes open, he’s pressed tightly against Kacchan’s chest with the alpha’s muscled arms wrapped around him protectively, tucked into his side, feeling the steady rise and fall of his chest under his cheek.
His eyes flick up to Katsuki’s face, the alpha looks so angelic in the soft morning light that highlights his sleeping features. Izuku reaches a hand to brush his finger tips across the sharp surface of his cheek bone, a tiny purr rumbling in his chest as he soaks in having his alpha here with him.
In his head, he still struggles to accept this is all in reality, though he’s sure Katsuki would smack him over the head if he said that out loud. His hand strokes down further until he cups Katsuki’s cheek in his palm, snuggling his head deeper into the crook of Katsuki’s neck, huffing in his spicy scent laced with sleep, purring deeper.
“Morning to you too” Katsuki’s gruff voices reaches his ear, Izuku jumps back in surprise like a kid caught stealing from the cookie jar.
“I wasn’t asking you to stop” The blond alpha chuckles, propping himself on his elbow, Izuku blinks up at him, eyes shining with awe at the gorgeous alpha above him.
“You want me to scent you, huh?”
It’s like the alpha can read his mind, thought he supposes it isn’t hard to work out what’s he wants when he’s already so enthralled with Kacchan. He gives a curt nod his head, feeling his face heat up under Katsuki’s affection.
Izuku obediently displays his neck, and consequently his brand new mating mark that sends a stab of possessiveness through the larger of the two alphas.
“Love seeing my mark on you” He growls as he surges down to rub his neck on Izuku’s, his scent growing increasingly stronger by the second, filling Izuku senses with spicy goodness with the sweet undertone of melted caramel.
Scarred hands clench tightly onto his mate, another purr escaping as much as he tries to hold it in, embarrassed by his non-alpha like response, still not used to letting into his desires. Sharp fangs nip at his neck, making him shudder, body going limp in his eagerness to submit.
When Katsuki deems him thoroughly scented, he pulls back with a pleased alpha chuff, hand reaching up to tilt Izuku’s chin so he can press a gentle kiss against his lips. It’s bliss, lying pressed naked to his mate, their lips interlocked and the scent of his alpha clinging to his skin.
Large hands thread through green curls and tugging gently, forcing huffs and whines out of the smaller alpha. Smaller, scarred hands run over dense muscle, kneading like a kitten working for milk. Their lips move seamlessly, slow and fluid, like they’d done this dance a million times, yet it’s still such a new and raw experience that it makes electricity thrum under the surface of their skin.
Katuski pulls back, licking at his lips, a grin that shows off his glinting fangs graces his features when Izuku leans forward to chase his mouth.
“We gotta get ready, class starts in a bit, you don’t wanna get me riled up”
Eyebrows furrowing, Izuku pouts, reluctant to leave the security of their den, the beginning of panic rolling in his gut as he imagines the judgemental looks that their peers may throw their way.
“Hey, what’s wrong?” Kastuki easily picks up the note of fear in his scent, his stance stiffening up at his mate’s suddenly soured mood.
“We’re going down... together?” Izuku shifts nervously, picking at the quilt between his fingers, his eyes adverted from Katsuki’s face.
Though, he can feel Katsuki’s burning eyes on him, the blond alpha tilts his head, frowning. It’s no secret that Izuku was avoiding him before and made absolutely sure to steer clear of him, but he thought last night had put that to rest, that Izuku would feel comfortable around him and they’d be able to act like proper mates, like they’d both always wanted.
“Why wouldn’t we?” He can’t help but let a little frustration slip into his voice, instantly regretting it when he sees the tears lining Izuku’s fearful eyes.
“What if someone... we’re alphas... they’ll say- ”
“And who cares?” Katsuki grumbles, puffing up his chest in a image of alpha pride. “If anyone dares say anything to you I won’t hesitate to rip their damn head off”
“Even if-“
“I said anyone and anything, damn nerd”
Izuku huffs a tiny giggle, unable to stop himself from laughing at Katsuki’s brashness, he always found it endearing.
“Kacchan’s so confident. Sorry for being stupid” He sniffles, pushing himself up from the mattress, grimacing as the ache in his behind worsens as he moves.
“If you apologised every time you acted stupid, you’d never stop apologising”
“Hey!” Izuku gasps, he feels strong arms wrap around his frame pulling him back even as he tries to wriggle away.
“I scented you and now you stink like sad alpha, lemme fix that”
“No, Kacchan is mean”
“You think it’s hot when I’m mean though” He bites at Izuku’s cheek, growling as the other alpha struggles against him.
“No I don’t” He yells back defiantly, biting his smaller fangs into Katsuki’s hand that grasps around his wrist.
“Last night would tell a different story” He chuckles teasingly into Izuku’s skin, dripping his head down to bite at his mating mark, that is still sensitive.
In a swift move, Izuku twists around, toppling them over so he’s perched in Katsuki’s lap, pinning him to the bed. A menacing grin overtakes the surprised look that momentarily appeared on Katsuki’s face. Suddenly, Izuku is very aware that they are very much naked and pressed extremely close together.
“Feeling brave, are we?” Katsuki bucks his hips up, letting his flaccid cock rub against Izuku’s ass. The alpha in his lap whimpers, his own hips jerking back.
“Fuck- wanna see you ride my dick”
“Ah please, Kacchan” He cries out, cock hardening between them, he desperately pushes his ass back for any contact.
“Yeah? You want that too? To bounce that fat ass on my dick?”
“Mmhmm” Izuku agrees mindlessly, the ache in his ass forgotten as his thought only centre around getting Katsuki’s dick back inside him. He clenches tight onto Katsuki’s wrists, eyes pleading for the other alpha to take some pity on him as he continues to watch his display with a amused smirk.
“Yeah baby, let-“
There’s a knock at the door before Kirishima’s loud, brash voice fills the dead silence that follows.
“Hey man, you’re later than usual. You even awake?”
Izuku blanches, eyes wide with shock, he springs out of Katsuki’s lap and pulls a blanket around his shoulders like somehow Kirishima can see them through the closed door.
“Tch, damn idiot, ruining my morning” Katsuki growls, he pushes himself off of the bed, snatching his sweats from the floor. He tugs them on then angrily stomps to the door.
“Hello? Baku-“
Nearly tearing the door from its hinges, Katsuki pulls it open, eyes glaring at Kirishima with the amount of burning rage only one Bakugou Katsuki could muster.
“Oh hey man” Kirishima laughs nervously, hand reaching up to rub at the back of his neck.
“I’m gonna give you a chance to save yourself” Katsuki states, voice laced with threat - Izuku isn’t entirely sure he’s joking.
“I was just gonna ask-“
It takes one sniff for Kirishima’s friendly smile to drop, his face contorting with confusion.
“Midori-“
He doesn’t get a chance to finish before the door is slammed in his face. Izuku flinches at the impact, or maybe it was Kirishima’s tone in which he said his name that has the fear burrowing back into his mind, like evil little maggots.
“Don’t listen to that idiot, he’s just mad I got laid before him”
Seemingly, Katsuki is unaffected, he busies himself with getting dressed, pulling on his school uniform. Izuku pulls the blanket saturated with Katsuki’s scent tighter around him, nuzzling his head into the fabric. He imagines Kirishima has already begun to spread the news amongst their classmates, maybe they’ll tell their teachers too. Would they then tell their parents? What will they all say? That they’re both sick in the head?
“Come on you gotta get dressed, who’s gonna give my ass a run for its money if you’re not there?” Katsuki teases, ruffling up his blond spikes into their usual messy style, from where his hair had flattened in his sleep.
Izuku doesn’t respond, his body trembles, fear trickles down his back like ice cold water. He ducks his head down, hoping Katsuki can’t see the tears building in his eyes.
“Earth to Deku” Katsuki pads over, he takes one look at the other alpha and sighs.
“I told you to ignore that idiot, he’s probably just trying to work out how alpha on alpha sex works in his damn pea brain”
Still silence.
“Deku, I swear-” Katsuki groans, scrubbing a hand down his face. A tense few beats of silence follow, Izuku can’t bring himself to look up scared of what he might see in his mate’s eyes.
“Do you regret what we did?” Katsuki’s voice is small, vulnerable. Izuku’s head snaps up.
“How could you think that? You’re all I’ve ever wanted Kacchan, it’s not that-”
“Then what is it? You just don’t ever want to be seen with me?”
Tears of frustration burn in Katsuki’s eyes, his hands clenching at his side, hurt written across his features. A stab of pain jolts through Izuku’s heart, this isn’t what he wanted at all. All he’d wanted was to be with Kacchan, now that he’s had it all for one fleeting moment it feels like it will be torn from his hands at any second when Katsuki realises the mistake he’s made.
“Not at all, I just... we can’t just...”
“Can’t what? Just spit it out or I don’t think we have any chance of this work-“
“I’m an alpha!”
Katsuki barks a laughs but it’s void of any actual humour or lightness.
“Yeah, I think we fucking established that and I already told you-“
“But you don’t think about what that means”
That makes Katsuki’s mouth snap closed, some of the tension slips from his body, his shoulders slumping slightly.
“What are you talking about? What do I need to think about? We want to be together, end of story”
“And if we both go into rut? What if we hurt each other?”
The dam break and Izuku feels tears drips down his cheeks, the thoughts he’d been fighting so hard to hold in spill out.
“Then we’ll deal with that in the moment, there will be ways”
In the back of his mind there’s an unyielding sense of guilt like he’s taking away a vital part of Katsuki’s life that he would have if he was with an omega. He knows that’s what people will say, that he selfishly stole Katsuki away from ever having a normal life.
“I can’t give you pups” Izuku sniffles sadly.
“Then we’ll adopt. There’s plenty of brats out there, looking for a home”
His heart soars as he imagines having a pup with Katsuki, a tiny hand wrapped around Katsuki’s finger as he coos over their bundle of joy. Even if the pup had none of their genes, they’d both love them as if they did.
“But-“
Katsuki’s hand shoots out to grasp at his chin to shut him up, he leans in over the edge of the bed. His breath ghosts Izuku’s lip, brilliant red meets watery green as their eyes hold each other’s gazes, each unwavering in their intensity.
“Izuku, you damn idiot, there’s nothing you could say that will ever stop me wanting to be with you. Now stop trying to sabotage your own happiness for a damn minute, got it?”
Pursing his lips into a wobbly line, he manages a quick nod of his head, Katsuki gives a small smile and leans in the rest of the way to press their lips together chastely, tasting the salty tears dripping down Izuku’s face. Izuku kisses back eagerly, determined to show Katsuki how much he wants him, that his worries didn’t affect that, no matter how loud they got in his head.
“I’m sorry” He whispers against Katsuki’s lips as the alpha sets himself back.
“Told you, you’d never stop apologising”
“Wah-“
He can feel where Katsuki’s grin presses into his cheek as the alpha snorts.
“Hmph, alpha thinks he’s funny”
“Oh I know I’m funny, little alpha”
When Katsuki attempts to straighten himself up, Izuku throws his arms around his neck, tugging him back, not wanting to be apart just yet. Large hands smooth up and down his back, he nuzzles his head into the crook of Katsuki’s neck, his scent helping to soothe him further.
“You feeling better?”
Izuku sits back, rubbing at his tired eyes, he nods.
“Good, get ready, we’re going out”
“Eh? Right now? During school?”
“Hell yeah”
Izuku’s cheeks heat up at the implication.
“Like a d- date?”
“Duh” Katsuki sniggers like it was obvious and they hadn’t done this whole courtship and mating thing backwards.
He raises an eyebrow, looking at Katsuki like he’d gone mad. The taller alpha starts undressing, unbuttoning his school shirt.
“Kacchan is serious?”
“I still got those tickets to the Hero’s Age exhibition, you saying you don’t want to go?”
It only takes a fraction of a second for Izuku to make up his mind, imagining all the hero merchandise and exclusive information he’ll have access to - and of course ,importantly, a day out with Kacchan.
“I’ll get ready!”
.
Sneaking off of school grounds is almost worryingly easy, they simply stroll out of the gate in their civilian attire. The weather isn’t exceptionally interesting either, fluffy clouds hanging in the blue sky, a light breeze ruffling their hair and it’s a quiet day, with everyone being in work or school. They walk down the street towards their destination, small talk filling in the time as they debate the outcome of different hero match ups.
“You’re crazy if you think Hawks could beat Miruko, Deku”
“I’m just saying it’s possible, they both rely on speed, I’d say they’re evenly matched”
Katsuki scoffs, mumbling something under his breath that sounds suspiciously like ‘idiot’. They fall into a easy silence, side by side, shoulders occasionally bumping as they stick close together. Izuku’s breath hitches when he feels Katsuki’s knuckle brush against his hand, he glances to the other alpha, noting the furrow in his brow and light blush on his cheeks. It makes him smile, seeing Katsuki all bashful from the thought of casual affection as if they hadn’t done stuff far more intimate.
In a surge of confidence, he grabs at Katsuki’s hand, squeezing it tight. Katsuki freezes up and it makes Izuku smile wider, giggling as Katsuki turns to scowl at him, though he feels him squeeze back even tighter.
It only takes a little while longer to arrive at the exhibition, the large posters of heroes hanging out front making it clear they are at the right place. There is no queue outside, giving Izuku hope that inside will be rather empty, meaning no judgmental eyes will stare their way.
“Come on!” Izuku yells enthusiastically, tugging Katsuki along like an overexcited dog on a leash.
“Hold your damn horses” Katsuki protests yet lets himself be dragged inside the large building. Their eyes sparkle with interest and awe as they take in the wonderful sight of hero exhibits, statues and posters, decorating the hall in the way only Izuku’s dreams could imagine.
“Good day, do you have reserved tickets?”
The warm voice of the vendor greets them, a bright smile on her face, from her stature and scent, it’s clear she’s an omega. Katsuki’s hand feels like a weight in his hand as her gaze rests on them like at any moment she will pick up on his gender and the warmth will vanish. Despite the rush of nerves, Izuku returns her sentiment, giving a wobbly smile back.
“Take these, imma go piss” Katsuki states as he drops Izuku’s hand and slaps the tickets against his chest before stalking off. Izuku scrambles to catch them, giving an embarrassed squeak.
“Heh heh” He chuckles awkwardly as he slides the tickets onto the counter between them, face flaming pink as the vendor continues to smile. She thanks him as she collects the tickets, turning to type something on the computer at her side.
“These are full the full package, your date is spoiling you” She winks at him, her blue eyes lighting up with happiness as she slides him the exclusive lanyards.
“I- um... yeah.. he- I guess” He stammers our in a rush, hand reaching up to swipe the lanyards off the counter, the vendor laughs, cheerfully, not in the mocking way Izuku had convinced himself he’d hear.
“This place is great, I was thinking of bringing my omega here, he loves heroes too” She announces, a prideful smile on her face.
That’s when Izuku notices the mating mark on her neck over the collar of her uniform, smaller then the size you would expect from an alpha, he’s flooded with relief. His eyes glance back up to her face practically beaming with pride at the mention of her mate, he realises how much he wants people to see the same look on his face when he talks about Katsuki and not the panic that he feels every time he even thinks about telling people.
“That’s a great idea” He smiles genuinely, eyes softening. They share a moment of understanding, it’s like a weight off his shoulders.
“Heads up” She nods at him, he blinks in confusion before he feels an arm slide around his waist.
“We good to go?” Katsuki voice is low against his ear, tugging Izuku closer, almost possessively.
“Yeah” Izuku giggles, turning his head to nuzzle his alpha comfortingly, catching the suggestive wink the vendor throws his way.
“You guys enjoy your day” She waves politely.
“Thank you” Izuku waves back as Katsuki steers him away, leading him into the main hall.
“Kacchan, what’s gotten into you?”
“Don’t like the way she was looking at you” The alpha grumbles, petulantly.
Izuku laughs, yet he slides his hand down to grip Katsuki’s hand again, holding it tight.
“I don’t think you have to worry, let’s just enjoy this”
“Who said I wasn’t enjoying this?”
“Mmm yeah but heroes, Kacchan” Izuku hums, relishing in the way Katsuki grips him tighter, enjoying the attention.
“You saying you’d rather look at heroes than me?”
“I don’t think you want me to answer that”
“You cheeky little bastard” Katsuki growls, nipping at Izuku’s cheek, making him break down in giggles.
“Ok ok I’m sorry, let’s go, people are gonna stare” He gets out between pants, Katsuki’s red eyes scan over the room, daring any of the few people scattered about minding their business to look.
“Nah we’re good”
“Ok, scary alpha, I’m sure they’re all terrified” Izuku reaches up to press a kiss to his cheek, Katsuki hums in agreement before he catches the sarcasm in Izuku’s tone, eyes dropping to glare at him instead.
“Look Kacchan!”
Before Katsuki can open his mouth he is dragged away, letting Izuku lead him to one section of the room. It’s entirely All Might themed, a large stature of the man holding his signature pose in the centre with many newspaper clippings and candid shots of the hero at work on the walls surrounding it.
Izuku’s eyes drift around in complete admiration, not knowing where to look first. He walks along the wall, scanning each photo with rapt attention, Katsuki trailing along behind him.
“You’re meant to save the best for last”
He slides up behind Izuku as he stops at one particular photo, he perches his chin atop messy curls, his hands curling around his waist.
“Do you think we’ll have something like this one day?” Izuku comments absentmindedly.
“Probably but I know my section will definitely be bigger”
Izuku tilts his head back, pouting up at Katsuki’s smirking face.
“Maybe we’ll have a section together, the wonder duo special” Katsuki placates, watching the annoyance drain from Izuku’s face, replaced with unbridled happiness.
“I would like that”
“Obviously your sappy ass would”
They take their time around the rest of the exhibits, hand in hand, Izuku’s excited ramblings and Katsuki’s cutting remarks are the soundtrack to their afternoon. There are many well known heroes careers being displayed here, Best Jeanist, Gang Orca and Endeavor just to name a few, Izuku wishes he brought his notebook so he could write the information off the plaques down, so he settles for typing it onto his phone instead.
The exclusive part of the tour turns out to be a hero seminar given by local rookies talking about the plights and troubles of becoming a hero in this day and age. Izuku takes his seat and listens intently to every word, nodding along while Katsuki rolls his eyes at the cliche sentiment and drags Izuku out early to continue looking at the exhibits that he’s actually interested in.
A few hours pass, they make it to the other side of the hall, where the merch store is located. Izuku’s eyes light up at the prospect of buying something hero themed.
As he strolls inside his eyes are instantly drawn to a large All Might plushie, he drops Katsuki’s hand to rush over to pick it up, amazed at how soft it is.
“Look, I definitely need this” He turns to shove it in Katsuki’s direction so he can see it, smiling wide.
“I’ll get you it, think of it as a courting gift”
“Wah- I don’t n- need a courting gift” He stammers, though the thought of Katsuki getting him a gift has him stifling a purr into the fabric of the plush, his scent bleeding through with pure joy.
“Well I didn’t ask if you needed one”
“I will buy Kacchan something too!”
For a second, he thinks Katsuki will take offence, since receiving a gift is a predominately omega thing, or in their case, a submission thing. He’s surprised when Katsuki fixes him with a smirk and turns around to one of the other shelves.
Izuku watches with curiosity, and slight worry for his bank account, as Katsuki scans the rows and rows of figures, comics and clothing items, and snatches something off too fast for him to see.
“This will do”
He holds out his hand to present a miniature All Might keychain, depicting the hero in his silver age costume with his signature smile on his face.
“That’s all?”
“Mm I’m not as spoiled as you, princess”
“I’m not a princess” He whines, though Katsuki doesn’t seem convinced. They purchase their items, Izuku picking up an extra set of All Might stationary on the way to the till, that Katsuki rolls his eyes to but secretly knows he’ll be borrowing from.
Next, they make their way to the cafe that is adjoined to the hall, Izuku’s stomach rumbling as he realises just how hungry he is. Katsuki orders them two bowls of pork udon, one extra hot and Izuku is especially pleased when they are both presented with a complementary All Might themed banana milk shake with fruit decals looking like the hero’s signature hair sticking from the whipped cream.
They tuck into their food, slurping up their noodles with enthusiasm before moving onto their shakes.
“Do we... have to go back so soon?” Izuku asks, swirling the straw around the bottom of the glass.
“Why delay the inevitable? Aizawa’s gonna have our hides for ditching, I’m sure us being mated won’t even come up”
Izuku drops his eyes sniffling sadly, it only takes a beat for Katsuki to sigh dramatically.
“Jeez fine, the fuck are we meant to do then?”
Having not thought this far into his plan, Izuku wracks his brain, he remembers the last chat he’d had with his mum.
“My mum is visiting family, we can go to my house for a bit”
Katsuki hums, squinting his eyes before something seems to click and he smirks dangerously.
“That’ll work”
.
Travelling back to their hometown on the train, Katsuki keeps close to Izuku, letting his scent soothe his mate’s nerves as the smaller alpha clings to him. Katsuki takes a glance at his phone and sees the absurd amount of texts and missed calls covering his home screen, rolling his eyes - damn Shitty Hair.
They get off at their stop and hurry home, Izuku seems to perk up when they reach the door since he’ll be in the comfort of his childhood home and its familiar scent. Izuku takes the spare key from under the doormat and lets them in, they rush to kick off their shoes, sighing at the relief on their over worked feet.
“I’m back in this fucking nerd kingdom” Katsuki teases as he steps straight into Izuku’s bedroom and flops back on his All Might bed sheets and lets his eyes rove over the merch covering the room.
“It’s not that bad” Izuku moves to crawl into his alpha’s lap, plopping his plush down onto Katsuki chest. It doesn’t even last a minute before Katsuki growls and tosses the plush away.
“Ah- what did you do that for!” Izuku squeaks, attempting to get up when he is stopped by large hands gripping his hips.
“I don’t want All Might staring at me when I do this”
He sits up in a flash and his lips catch Izuku’s in a deep, heated kiss, his tongue scorching as it laps deep into his mouth. Izuku’s mind catches up to the present and he moans into Katsuki’s mouth, his hands shooting up to grasp at his shoulders for support.
With a final peck, Katsuki pulls away, confident smirk pulling at his lips. His hands drop lower to grip Izuku’s ass, massaging his fingers into the plump flesh over the fabric of the other’s alpha shorts, clear as day Izuku can feel Katsuki’s hard dick under him. Determined hands grip at the bottom of his shirt, pulling it over Izuku’s head, Katsuki let’s his hungry gaze roam over his toned body.
“We can’t do this here, we don’t have any-“
“Shh shh” Katsuki shuts off his protests with another quick kiss, one of his hands pulls away to reach into his pocket.
“You carried that with you all day?” Izuku winces as Katsuki produces a small container of lube from his pocket.
“I wanted to be prepared wherever we ended up”
“You’re such a- oomph”
Izuku is roughly flipped onto his back, Katsuki now leers above him, his eyes darkening at the prospect of what’s to come.
“You gonna let me fuck you, baby?” His voice is a low drawl, it lights Izuku’s core red hot, filling him with overflowing want and lust. His body, thought the sexual frustration has lessened, still craves almost painfully to be fucked and used by his alpha.
“Y- yes” He whines, trying desperately to pull his legs up to give Katsuki the room he needs.
“Aww you need it bad huh?”
Katsuki moves to grip the waistband of his shorts, as Izuku frantically nods his head, keening high in his throat as his shorts and underwear are tugged off and his hard cock is exposed to the cold air of the room.
“Knotted you last night and you’re still gagging for it”
“Please please” He sobs, gripping onto the back of his knees, nails biting into the soft skin, to expose himself to his mate. Katsuki lets his eyes linger hungrily on Izuku’s twitching hole, watching the desperate display in front of him.
The familiar click of the lube opening sends a shudder up Izuku’s spine, his body knowing, and wanting, what’s to come. Katsuki lubes up his fingers generously, pouring more directly onto Izuku’s hole for the hell of it, he drags one finger through the mess and lets it catch on the waiting entrance.
Izuku sucks in a harsh breath as he is breached, Katsuki’s finger quickly pushing in to the third knuckle since he is still slightly loosened from last time.
“You like how my finger feels?” Katsuki asks as he drags the digit in and out, slowly, feeling every ripple and clench as Izuku sobs for more before he pushes back in with two fingers. Inside, Izuku is scalding, Katsuki’s cock aches remembering what it was like to buried in such a tight heat.
“What? My fingers not enough for you?”
Tears pools in his gleaming eyes, he shakes his head, his cock drooling profusely onto his stomach and scent thick with lust around them.
“Then what? Come on” Katsuki urges, he needs to hear it as much as Izuku needs him physically. He craves to hear how desperate his mate is for him, he thrives knowing his knot is the thing that can satiate Izuku’s appetite.
“Need Kacchan, need Kacchan’s knot in me so bad“
Katsuki feels the last his resolve snap, now no longer able to keep up his teasing, he kicks his sweats and underwear off and pulls his shirt off, dropping to his elbows, boxing Izuku in, not bothering with any more lube as he pushes the head of his throbbing cock in. Izuku cries out at the intrusion and the rational part of Katsuki’s mind warns him about neighbours hearing and people being called, he quickly clamps a hand over Izuku’s mouth, forcing down any noises that try to escape.
“Argh fuck-“ Katsuki groans at the combined stimulation of pushing further into Izuku’s hole and the feeling of the other alpha’s fangs biting into his hand.
“Shh, you can take it” He soothes, catching Izuku’s gaze, seeing the conflicting emotions flash in his eyes. It seems like eons before Katsuki’s hips finally press against Izuku’s ass and he can pull his hand away, using his thumb to swipe away the tears cascading down his face.
“Good boy, always so fucking good for me”
At the praise, Izuku sobs harder, his hole throbbing in pain and pleasure around Katsuki’s length, his hazy eyes blinking lazily as he watches the form of his mate above him. Katsuki starts up a slow pace, hips rocking as he lets his mate adjust, as his half-formed knot already presses up against his rim.
“More p- please”
Katsuki lets Izuku’s pleads hang in the air for a second, not wanting to risk hurting him but also trying to fight down the carnal need to fuck, and fuck hard.
“Please, alpha” It’s a tiny whimper that feeds directly to Katsuki’s cock.
It’s like an elastic band tightening and snapping as Katsuki loses all pretence of holding back and keeping things quiet, instead he grips his fingers deep in the quilt as leverage to gain traction and speed to fuck cries and sobs out of his mate underneath him.
His hips work at a maddening pace to constantly stimulate Izuku’s prostate, the sound of their fucking loud in the room as sounds of skin on skin echo off the walls. Smoke rises from where Katsuki’s hands clench tight into the fabric of Izuku’s quilt, growls and groans spilling from his mouth. Izuku fairs no better, he can do nothing but let his body go lax and allow Katsuki use him, whining thin and high in his throat.
“Gonna -fuck- knot you, gonna fill you up”
Katsuki snarls into Izuku’s ear, his releases teetering on the edge. He forcibly shoves his hips a few more time and manages to tie them together, his cock spurting seemingly endless ropes of come deep in Izuku’s hole. At the point when they become knotted, Izuku comes with a final weak sob, his knot popping and cock covering his stomach with come, he drops his knees to wrap his arms right around Katsuki’s neck, needing him close.
Arms shaking as he holds himself up, Katsuki pants deeply, nuzzling his head into Izuku’s neck as his scent is laced with the addictive hint of pure bliss. He carefully rolls himself onto his side, cradling Izuku to his chest, the other alpha whimpers as the knot is tugged on.
“You did so good, baby” Katsuki soothes Izuku through the aftershocks, grooming him and stroking his hands over his sensitive skin.
Through the window, Katsuki can see the sun is just starting to set, the pit of dread in his stomach opens as he imagines dealing with the consequences of their actions in the near future but one look back at Izuku curled against his chest, smiling sleepily and it’s all worth it.
He lets his eyes shut so he can bask in peace a little while longer, when he hears Izuku whine sadly, he’s instantly alert.
“What’s wrong? Does it hurt?”
Izuku looks at him in that teary eyed way that makes his heart ache, his lip wobbling as he struggles for the words.
“I want- ... m- my All Might plushie”
Katsuki takes one glance across the room where the plushie lays abandoned at the other side across from the bed and he drops back with a sigh. It takes some struggling with Izuku held clinging tight against his chest for him to be able to retrieve said plushie and get them back into bed with no casualties.
“I regret buying you that now” Katsuki grumbles, which Izuku pays no mind to as he snuggles himself into Katsuki’s chest and holds the plush close, making that it gets coated in a thick layer of their combined scents.
Ok maybe he doesn’t regret it as much anymore ‘cause his mate looks damn cute.
“Kacchan is jealous because All Might plush gives better cuddles?”
Scratch that.
“Don’t make me throw it again”
Izuku giggles joyously, pressing kisses along his jaw to soothe out the frown on his lips, which the blond alpha stubbornly refuses to give up.
“Maybe you should get me a Kacchan plushie then”
“When you’ve got the real thing right here?”
“Hmm you’ve got a point”
Strong arms tighten around him, Izuku sighs into the touch, letting his eyes flutter shut. Nothing on their minds as they let the minutes slip by, fingers threading together, bodies still tied together in the most intimate way.
“We gonna have to go soon, Kirishima’s gonna start hunting us down” Katsuki comments, yawning wide as he checks his phone again.
