Private chat between Izuku and Shoto
Shoto
so you had the medicine ball, headphones, and everyone has to wear scent blockers in the gym
Shoto
I fail to see why this is making Bakugo crow so loudly in the general chat
Shoto
also he seems to have lost his shirt.
Izuku
hnnnnnnnnngh.
Shoto
the pictures are right there.
Shoto
you can look
Izuku
I don’t trust myself.
Izuku
it is very warm and dark and cramped in this locker.
Shoto
kinks aside… what happened, Izuku?
Izuku
do I HAVE to tell you?
Izuku
it’s so embarrassing
Shoto
I can practically sense you squirming through the phone
Shoto
honestly it’s making it hard to relax
Shoto
you’re in distress. Do you need me to come get you?
Izuku
omg no
Izuku
sho stay there. I’m fine
Izuku
Sero make sure he doesn’t come down here. The last thing this needs now is for him and Kacchan to get into an alpha snarling match.
Shoto
yeah sure
Shoto
Hanta get off my phone!
Shoto
Fine. I ‘ll stay here.
Shoto
but you have to tell me what happened.
Izuku
ok
Izuku
fine.
Izuku
(deep breaths)
Izuku
so you need to remember that I didn’t realise Kacchan was even there.
Shoto
yes. Come on Izuku, this is slow even for you.
Izuku
and apparently he was setting up to do bench presses with the free weights…

Bakugo
I know you said I shouldn’t hunt him down
Bakugo
but-
Kirishima
I’m not going to like this am I?
Bakugo
can I steal and scent mark his clothes instead?
*
Izuku looks up from his phone, turns off the screen, and pockets it. He gulps.
Shoto was right. Izuku should probably tell him so. But he can’t right now, because if he looks back at the general chat and sees all the things Kacchan wrote and posted again, he’s going to scream.
Instead, Izuku takes stock of the situation, putting his over-thinking analytical brain to good use so that the rest of his mind can have a full gay meltdown panic in peace.
-
He is in a locker, it is dark.
-
He and Kacchan are seemingly the only people in the gym.
-
He is hard, his underwear is tacky with slick, he feels warm all over.
-
Kacchan invited him to come back and sit on his face again.
-
Izuku is pretty sure his face is so hot right now it could be used to fry his dinner.
And Kacchan is out there somewhere, prowling around, apparently hungry. Izuku has been harbouring a crush bigger that Fatgum on his childhood friend since well before they presented; he isn’t going to pretend that he doesn’t imagine Kacchan to get through his heats.
Unless Izuku, Shoto, and the rest of Class 3-A have all failed basic reading comprehension, Izuku has plenty of evidence now to suggest that Kacchan likes him back, which is a world-changing revelation all by itself. Unless of course this is some kind of very elaborate practical joke. The third option – that Kacchan’s alpha instincts have been triggered by getting a face-full of unmated omega – isn’t worth considering, because Izuku is still dressed and unmolested.
Also, Kacchan is too cool to ever actually lose control. Kacchan is the best.
“Freckles…”
Izuku sticks his fist in his mouth to stifle his yelp. Kacchan’s voice is suddenly a lot closer than all of the random banging about in the gym was. Izuku is just considering maybe trying to peek out of the ventilation slots in the locker door when the light changes – a shadow passing across the locker he’s hiding in – accompanied by heavy, familiar footsteps.
“Come on out Freckles.” There is a thump, like Kacchan just slouched into a locker. Or maybe punched it. “You’re teasing me by hiding you know. Not very Hero-like.”
Izuku quivers all over. He wants to smash his way out of the locker, take up that challenge and make Kacchan eat his words. But he knows that’s exactly what Kacchan wants. He inhales deeply through his nose, and then regrets it instantly.
Kacchan has taken off his blockers. Either he’s sweated them away or wiped or washed or something, because he smells rich and smoky, like the best kind of campfire. And he must have rubbed himself over the locker door when he passed, because the scent is so strong. Izuku whimpers, feeling a fresh trickle of slick between his thighs.
“I know you’re here, Freckles.” Kacchan’s voice is louder, closer, deeper. Izuku bites his lip; he’s not going to whine again, he has self-control.
A shadow falls over the door again, the harsh light of the locker rooms obscured by the bulk of the alpha hovering outside.
“I’ve got you in my nose now, pretty omega…” Kacchan’s words trail off into a soft chuff.
It is a warm, welcome sound, an invitation from a handsome, unmated alpha, towards a hopefully reciprocal omega partner. Every single one of Izuku instincts screams at him to go to the alpha who makes that sound and smells so good and is clearly giving himself over to him. And it’s Kacchan… there has never t been a time Izuku wasn’t at least slightly in love with him, even before he really understood what those four letters meant.
From outside the locker, there is a big, heavy sigh.
“Alright Freckles. I’ll leave you to it. I scented your shirt, sorry. You got a spare? I’ll wash this one.”
Izuku squeaks behind the hand still wedged in his mouth and stares with wide eyes as Kacchan’s shadow drops away.
He’s leaving.
Kacchan wants him, isn’t teasing him, and is respectful enough that without consent he’s leaving.
Izuku’s omega instincts explode.
How dare his alpha leave?!
Izuku drops his phone, slams open the locker door, and finds Kacchan turning to face him, his expression morphing from resigned upset into feral delight.
“Izuku…” Katsuki rumbles, and then Izuku crashes into his front, eager hands digging into the alpha’s blond spikes in order to crash their mouths together.
Neither of them are gentle, and the kiss is everything. Kacchan’s fangs are sharp against Izuku’s tongue, Izuku can taste blood, licking at the nick in Kacchan’s soft lips. He clings tight to Kacchan, loving the feel of those big, hot, powerful hands travelling across his back and down over his arse.
“Kacchan,” Izuku whines into the kiss, nearly trilling at the end of his name. “Alpha.”
“Nngh- fuck. Freckles, you smell so good.” Kacchan uses one hand to tilt Izuku’s head, thumb pressing over his pulse point. Kacchan noses around his scent gland, chuffing, licking, tasting. “How dare you hide this from me?”
Izuku responds by turning into Kacchan’s touch, sucking that thumb into his mouth, meeting Kacchan’s fiery gaze and smiling.
“You fucking- tease.”
“Kacchan tastes so good,” Izuku moans, licking his way down Kacchan’s wrist to the alpha’s scent gland. Katsuki realises what he’s doing and near-enough shoves his wrist in Izuku’s face. Izuku trills. “My alpha.”
“Oh, fuck yes. Mine.” Katsuki groans as Izuku bites his wrist, teeth sinking in beside the gland. “Fuck’s sake, Nerd. Do it properly.”
Izuku snarls, and bites him again, marking Kacchan as his.
Kacchan steps forward, gathers Izuku’s thighs up with both hands and pushes him back against the lockers.
“No more teasing. I’m all yours, Izuku. I gotta have you.”
“Alpha!” Izuku wails, at Kacchan’s words and the feeling of those big alpha fangs scraping over his neck as he speaks. “Kacchan- ahhh!”
Kacchan rolls his hips, and Izuku’s rational thinking brain short circuits as he feels Kacchan’s cock pressing against him. His instincts scream big, hot, hard, mine, mate. Izuku decides he doesn‘t want to resist the horny creature that lives inside his brain and usually only gets to come out in order to jerk off before bed.
“Yeah, that’s it Freckles.”
Suddenly Izuku’s knees are up by his ears and Kacchan is filling up all his senses.
“You’re mine.”
Izuku growls in response, fangs bared in an open challenge against the alpha who has him in such a strong grip. Izuku can feel slick between his cheeks, his own cock hot and throbbing, trapped within his straining shorts. Katsuki snarls back, face only an inch away, sweet woodsmoke filling the space between them, so different from the acrid tang of exploded concrete.
For a moment, Izuku is reminded of every fight they’ve ever had, every brief smile throughout the past couple of years, every might-be-imagined blush staining Kacchan’s cheeks pink when their eyes have met. Then he takes the plunge, and kisses Kacchan again.
Izuku ravages his mouth, one hand around the back of Kacchan’s neck, strong fingers digging into his scent glands and his nape, kneading in a way which – any other time – might make the alpha melt for him.
But not Kacchan, and not now.
Kacchan doesn’t break the kiss, but runs one hand down Izuku’s inner thigh while still holding up his knee where its hooked practically over Kacchan’s shoulder, and tears straight through Izuku’s clingy gym shorts and his underwear. Izuku yelps, but Kacchan merely chuffs happily, taking an obvious deep sniff of Izuku’s scent.
“Fuck, Freckles. You smell amazing.” Kacchan rubs his face into Izuku’s neck and his hair, scenting him all over. “I wanna fucking bathe in you.”
“Kacchan-!” Izuku whines, because his omega hind-brain wants nothing more than to scream mate, now! but Izuku likes to think he has some shred of self-respect left.
Kacchan apparently doesn’t have the same qualms.
“Mine,” the alpha promises, and then Izuku’s leg is slipping by an inch as Katsuki somehow discards his own shorts, allowing the thick weight of his cock to slap against Izuku’s slick hole. “My omega.”
Izuku trills, a sweet high note which burns through common sense, self-control, and tugs directly in the instincts of the alpha it is meant for: come, take me.
Kacchan wastes no time. Izuku gets a single breath to adjust to the blunt head pressing against his rim, to the spread of Kacchan's cock, and then Kacchan is fucking him back against the lockers, spearing Izuku so deep that Izuku chokes.
Kacchan growls, Izuku wails, and then his world narrows to crimson eyes and Kacchan’s heated breath, and the feeling of the alpha fucking harder and deeper inside him with every single heartbeat. Izuku pants, taking in each of Kacchan’s breathes and making the alpha trade them back and forth until everything between them is flavoured with sweet barbecue and aloe. Kacchan’s forehead rests against his own, eyes fixed together as he crushes Izuku into the locker.
And Izuku loves it.
“Ka-aaahh- cchan…” Izuku can barely speak between trying to breath and the fact that Kacchan is rearranging his insides to suit him and only him. Izuku’s inner omega purrs, perfectly content to belong to such a powerful, worthy alpha.
“Yeah, that’s right, Freckles.” Katsuki sounds confident, strong, but Izuku can see how his pulse jumps in his throat, how his arms and shoulders shake with the effort of holding Izuku’s weight, how his cheeks are flushed with emotion and exertion. “Ruin me for anyone else. My omega.”
“Alpha.”
“Yeah,” Kacchan kisses him hard, grinding his cock in deep, and Izuku cries out when he feels the thick girth of Kacchan’s knot pressing against him, not yet inside. “Just for you, Izuku.”
The next thrust presses directly against Izuku prostate and the omega snarls, suddenly-sharp nails digging deep into the tender skin on Kacchan’s nape. Kacchan growls, deep and low – a threat – but Izuku simply trills again beseechingly, and drags Kacchan’s face down to the junction of his neck and shoulder, turning his own face upward to pant at the ceiling while Kacchan fucks him so hard that he can’t breathe.
“Fuck,” Katsuki chuffs. “Fuck. Omega. Mine. So good. Smell- so good.”
Izuku is getting dizzy, the lack of oxygen and an over-abundance of oxytocin is making his vision foggy but his instincts are sharp. This is his alpha, he wants everyone to know this is his alpha, and he wants to be the very best omega and take his alpha’s knot. Izuku cradles Kacchan’s head, fingers playing with his blond spikes, and he begins to purr as he feels Kacchan lick over his scent gland. His body reacts just like it ought, slick lubing the way for Kacchan’s cock until his knot is pushing and pressing at his rim, and Izuku is panting and whining against the side of his head.
“Want you,” Kacchan whimpers.
“Bite me,” Izuku pleads.
“Hnnngh- ah- ah fuck- Izuku-!”
Kacchan’s hips smack into Izuku’s arse, his whole body smashed up against the lockers, making them creak dangerously. The noises pulled from them both are loud and lewd, the squelch of slick, the slap of flesh, the high little cut-off whimpers from Izuku and Kacchan’s deep Alpha growls. Kacchan pauses long enough to scoop Izuku’s knees up more firmly into the crooks of his elbows, hands braced under Izuku’s armpits, and then he presses forward-
-and keeps pressing.
Izuku yowls, scratching at Kacchan’s back, nails biting into skin, legs shaking and foot kicking out into nothing. His body is ready, his instincts want, but it’s so much. The weight, the girth, the heat. All are indescribable. Kacchan chuffs, trying to reassure Izuku’s omega instincts, but doesn’t relent even when Izuku wails, his breath punched out of him by the pressure of Kacchan’s knot seeking to lock tight inside him. And then Izuku feels Kacchan’s fangs scrape across his neck, and his hands form fists in Kacchan’s hair as Kacchan knots him and bites him in the same instant.
Izuku keens, whole body taut and then relaxing all and once, every nerve ending flashing as endorphins flood through him, bathing him in rich smoky warmth and the feeling of safety, adoration, and home.
Kacchan is huffing against his scent gland, licking and drinking Izuku in, blending them both together. His hips rock and jerk in tiny thrusts, grinding his knot in deep, working the shaft of his cock against Izuku’s prostate until Izuku is practically sobbing in his arms.
“That’s it Freckles, that’s right. Come on baby, come for me. Come on my knot, omega. Make sure everyone knows we belong together.”
Izuku pulls Kacchan’s hair, dragging the alpha in to meet his gaze. Kacchan’s eyes are like fire but his lashes are thick with tears, and Izuku suddenly realises that Kacchan is only just about holding himself together, pushing himself to make his omega – make Izuku – come first.
“Kacchan…” Izuku whimpers, tears of too many good emotions to count tracking over his cheeks already.
Kacchan licks his freckles.
“Bite me, Izuku.”
He’s pleading as much as commanding, and Izuku is helpless to resist the pull of his instincts screaming at him to stake an indelible claim on his mate. He grabs Kacchan’s jaw, twists the alpha’s head to the side to bare his throat – exposed, vulnerable, delicious – and bites down hard over the swollen scent gland. Kacchan yells, Izuku’s mouth floods with the salt-copper-tang of blood, and his senses fog with caramelised sugar and woodsmoke and he barely draws breath once before he comes.
Izuku’s orgasm tears through him, whiting out his vision, stealing his voice and his sense of self. His body doesn’t matter, only the white hot core of heat and satisfaction of Kacchan inside him and around him: his perfect mate joining them together, and he blinks back into reality just in time to hear Kacchan growl.
“Fuck- Izuku- baby- fuck-” before Kacchan slams fully home and falls utterly silent as he unloads inside Izuku. Izuku can feel the alpha’s cock twitching and throbbing, hot as he spills thick come inside Izuku’s body. Izuku trills, crooning, licking thoughtlessly at Kacchan’s mating bite, rubbing his face into the wound and Kacchan’s skin and his hair, spreading their scent everywhere.
Kacchan is no different, tongue dragging roughly over Izuku’s bite before moving to groom him, arms winding tight around his body to keep him close.
As always, Izuku is the one who speaks first.
“Kacchan…”
“Freckles.” Kacchan kisses one, then bites Izuku’s cheek gently. “Fuck, you’re so cute.”
“Kacchan!” Izuku tries to swat at him. It’s not very effective, but the motion causes Kacchan to adjust his hold, Izuku wriggles and they both whine when the motion tugs at Kacchan’s knot and Izuku’s rim, and then they are toppling to the floor of the locker room.
Izuku buries his face in Kacchan’s chest, blushing furiously. Kacchan bursts out laughter.
“Dork.” A warm hand pets through his hair. “My dork.”
Izuku looks up at Kacchan – his alpha, his mate – and sighs happily. Then he notices he is currently using Kacchan’s chest as a pillow and begins to knead his pecs happily.
“Oh wow, they’re so plush and soft. I thought they would be harder, tense all the time like when we spar, but I guess that would be an unrealistic waste of energy for someone as-”
Kacchan sticks his tongue down Izuku’s throat. Izuku yelps, but sinks very quickly into kissing Kacchan back. His mating bite throbs when they lick at each other.
“Wow, not even getting fucked so hard I think I blacked out, stopped you from muttering for more than five minutes,” Kacchan quips. “But at least I know how to shut you up now.”
Izuku blushes. Kacchan’s cock is still inside him, but apparently the fact his childhood friend enjoys kissing him can make him embarrassed.
“You’d better not be thinking about starting another notebook, Freckles.”
Izuku gazes up at him with a plaintive expression.
“But there’s so much more new information to analyse.”
Kacchan rolls his eyes and sighs, but every line of his body, from his small smile to his scent, speaks of fondness.
“Well, I knew what I was signing up for.”
From the floor of the locker by their heads, Izuku’s phone vibrates.
“You wanna tell IcyHot not to worry? I don’t really want him coming down here all concerned and messing with our bond.”
“Also, we’re still… um… naked.” Izuku makes a gesture and wriggles very slightly, but Kacchan clamps a hand across his lower back, groaning, and keeps Izuku seated very firmly on his knot.
“I’m far less concerned about that, to be honest.”
“Hmmmm…” Izuku reaches for his phone. “No more thirsty selfies in the general chat. You’re my alpha now. No one else gets to drool over you.”
“If you drool on me, you’re not sleeping in my bed,” Katsuki says shortly.
“But Kacchan-!”
Kacchan kisses him again and even Izuku has to admit that’s it’s very effective.
Only once Kacchan prompts him again does Izuku remember to focus on his phone.
