Bkdk a/b/o where they’re roommates and Kacchan keeps hearing Deku’s vibrator

‼️mutual somno

It’s been two weeks since they decided to rent a place together immediately after graduating and landing sidekick gigs at Endeavor’s agency with Shoto.

It’s just practical, really.

Sure, maybe they ignored the fact that they’re both unmated and heats/ruts are very much a real thing, but they’re just kids finding their places in the world, so it’s okay.

Except, two weeks into their shared living arrangement, it is decidedly /not/ okay.

Because their rooms are a bit too close for comfort (see: cheap, small apartment), and Katsuki can hear /everything/ going down on the other side of his wall.

It’s the third night in a row now, the blond laying in his bed, wide awake at 1am as he listens to the soft buzz of Izuku’s vibrator, the omega’s soft moans going straight to his cock.

Katsuki grabs the bottle of lotion from his bedside table and slips a hand into his boxers, hissing at the cool feeling as he wraps his fingers around his aching cock.

He bites his lip, listening intently to Izuku’s soft whines and gasps.

He pictures Izuku’s legs spread wide open, the omega languidly rubbing the little vibrator over his clit and lips, moaning in delight at the pleasure.

Katsuki strokes himself from base to tip, pulling his cock free of its confines.

He imagines his hand is Izuku’s tight little mouth or pussy instead, because he’s always harbored a crush on the omega, even back when he bullied him and told him he was a worthless fuck - he’d go home and jerk his dick dry to the thought of Izuku’s crying face.

Sue him.

The sexual tension between them has reached an all time high, but maybe that’s just Katsuki’s wishful thinking.

But there’s no way Izuku doesn’t know what he’s doing when he “accidentally” drops the remote and bends over, wiggling his legging-clad ass in Katsuki’s face, right?

It happened a week ago, the two of them chilling on their couch watching horror movies when Izuku went to pause it for a bathroom break, dropping the playstation controller in the process.

“Oops!” He’d squeaked, practically diving for the controller, and Katsuki had nearly suffered an aneurysm at the site the fabric clinging to Izuku’s fat pussy, the perky globes of his ass jiggling as he blindly fumbled for the controller.

He’d basically sprinted to the second bathroom, furiously stroking his cock and nutting in an embarrassing thirty seconds.

Not one of his proudest moments, but a young, horny alpha has to do what he has to do.

-

“Kacchannnn,” Izuku whines, batting his lashes prettily when the alpha walks through the door. “What are we having for dinner tonight?”

Katsuki ignores the way his cock twitches. “I just got home, you needy fuck.”

“But I want Kacchan’s katsudon,” Izuku complains, twirling his hair around his finger, and Katsuki nearly snaps, because Izuku /has/ to be playing up the whole bimbo schtick, he /has/ to be. He’s always been the sweet, innocent type, but he can’t be this fucking naive.

“Blow me,” Katsuki barks, his face flushing red at his own knee-jerk reaction.

Izuku pouts. “I will, if that’s what it takes to get some katsudon around here!”

The air in the living room suddenly turns heated, the two of them staring at each other with narrowed eyes.

“I, um,” Izuku stammers, bolting up from the couch and running to his room.

Weird.

-

Izuku bites his plush blanket, whimpers of Kacchan’s name muffled as he runs his vibrator over his clit furiously, imagining Katsuki throat fucking him.

He’d be so rough, so ungentlemanly, pulling Izuku’s hair as he fucks into his throat until all he can taste, see, smell is /Kacchan/. He’d call him a desperate whore, slap his face with his big cock - and Izuku knows it’s big, has watched him change more than once.

And if it’s that fucking big when it’s soft and dangling between his thighs, how big will it be when it’s hard and angry, leaking precum at the tip, begging to slide into Izuku’s pussy?

Katsuki does end up making katsudon that night, awkwardly knocking on Izuku’s door and calling him out for dinner, the two of them avoiding eye contact as they eat and watch their favorite shows on the couch.

“So, uh, about earlier,” Katsuki says before Izuku can run off to bed.

“I didn’t mean it!” Izuku nearly screams. “I would never blow you, hah, you’re my best friend!”

Izuku grabs their plates, furiously scurrying into the kitchen and nearly dropping them in the process.

“Did I just get friendzoned?” Katsuki mutters to the empty room.

-

Izuku chews on his lips as he stands outside of Katsuki’s room, listening to the alpha’s loud snoring.

Just one look. Just one look, and then he’ll leave and keep this secret to his grave.

He can’t help it. He’s been lying awake for two hours now, working himself over to the thought of Katsuki again and again - he’s desperate, and it’s not like the blond will ever return his feelings, so he basically /has/ to do this. For closure.

Just one close look at his cock, and he’ll be okay.

Katsuki is a deep sleeper, not budging when Izuku slowly opens the door with a loud creak, feeling like a total pervert as he makes his way closer to the blond’s sleeping form.

Katsuki sleeps shirtless, his blankets thrown to the side because he runs hot due to his quirk. He’s starfished out on his back, mouth open in a guttural snore.

He’s only wearing boxers, and Izuku’s hands itch to pull them off, to see the object of his obsessions.

Swallowing, Izuku crawls into the soft bed, purring at the heavy, smoky scent of alpha.

Katsuki’s face is slack with sleep, free of his usual scowls and frowns, and Izuku wishes he could kiss him.

And so he does, pressing his lips to Katsuki’s gently, his breath catching in his throat at the feeling, his cheeks reddening as he swipes his tongue along the alpha’s bottom lip.

Shit, this is so fucked up.

TBC hehe

Pulling down Kacchan’s boxers is nothing short of terrifying, Izuku holding his breath and his eyes darting to the blond’s face every two seconds to make sure he’s still asleep and not about to set off a blast in Izuku’s face

Because that’s totally what he’d do, god, Katsuki would be so pissed, and Izuku would never be able to look him in the eyes again.

The omega bites his lip and pulls the boxers all the way down, shuffling them a bit to ease them down the alpha’s hips.

And then his eyes widen, because fuck, there it is. Kacchan’s cock, soft and huge and intimidating and immediately sending a rush of slick into Izuku’s panties.

Katsuki thankfully hasn’t stirred, his snoring continuing steadily.

Izuku’s hand flexes, sliding down Katsuki’s abs, whimpering quietly at the feeling of solid muscle there, strong and /alpha/.

His fingers are shaking as he runs them over blond, coarse pubes, the alpha’s v-line cut and mouthwatering.

“Don’t hate me, Kacchan,” Izuku whispers, wrapping his small hand around the fat cock laying limp and terrifying between Katsuki’s legs.

It’s warm, and Izuku’s face flushes when the length gives a valiant twitch at the stimulation.

“Oh,” Izuku breathes, the skin soft and smooth in his hand. “Kacchan…”

The omega runs his thumb over the tip, nearly squealing when the cock begins to harden ever so slightly, the shaft jumping in his grip.

“Kacchan’s getting hard in my hand,” Izuku whispers, scared and aroused. “Oh my god.”

The blond’s snoring breaks for a moment, and Izuku’s heart beats against his chest with nerves when Katsuki lets out a quiet, deep groan and promptly goes back to snoring blissfully.

Izuku’s hand is loose around Katsuki’s dick, and he begins to hesitantly move it up and down once he’s sure the alpha is fast asleep, his pussy uncomfortably wet in his sleep shorts as he touches a cock for the first time.

Is it fully hard yet? It has to be, right? It’s so big already, so much larger up close and personal like this, and it’s steadily getting even bigger, filling Izuku’s hand so much that his fingers aren’t even close to touching around it.

It stands proud and angry against the alpha’s abs when Izuku lets it go, situating himself between Katsuki’s spread legs, shuffling on the bed so that he’s face to face with the shaft, eyes nearly bulging out of his head when he catches sight of the massive balls below.

Katsuki’s boxers had been covering them before, but shit, fuck, what does anyone need balls that big for?

Izuku reaches down with shaking hands to feel them, gently massaging them between his fingers and pulling a guttural moan from Katsuki’s sleeping chest.

Taking a nervous breath, Izuku bends down, propping his ass up in the air as he kisses the side of the length shakily, his lips tingling with arousal at the contact.

He sticks his tongue out, cheeks burning red as he runs it along the shaft.

It smells like Katsuki’s body soap and the smoky, deep scent of alpha, and Izuku inexpertly twirls his tongue around the tip when he reaches it, body tight with arousal as he closes his lips around the head.

He’s sucking Kacchan’s cock. Fuck. He has Kacchan’s cock in his mouth.

Slowly and carefully, Izuku takes in another inch, his mouth slick and warm.

And then the length pulses, and Izuku’s eyes widen when it begins to grow even /more/, fully hardening in his mouth.

And oh god, it’s big, bigger than he thought it would be, and he’s suddenly not quite so confident he can handle this monster.

It already has his jaw aching around the thickness, his lips tight, eyes watering as he somehow pushes down even deeper.

It’s so hot, all he can taste is /Kacchan/, the vein on the underside of the shaft throbbing at it reaches full mast, filling Izuku’s mouth and leaving his pussy throbbing in sympathy.

When the time comes, will it even fit? It’ll ruin him for anyone else, leave his pussy gaping and sore and wrecked.

Shamefully, he wiggles his tongue back and forth along the cock, reaching under himself and sliding his free hand into his panties, rubbing his clit as he goes.

He’s soaked, and he moans softly as he finally relieves some of the arousal building in his abdomen, slick fingers circling his clit rapidly.

He bobs his head as much as he can, trying to open his throat to allow the shaft to slide in even further.

He chokes around it a bit, pulling off with a gasp to catch his breath, grinding against his hand and diving back down for more, desperate and horny as he swallows down as much as he can in one go.

He moves his slick mouth up and down languidly, drawing the cock deeper with every pass, relaxing his throat and finally, finally letting it slide deeper than his mouth alone can take, face red and heart pounding furiously.

He whimpers around it, and Katsuki moans deeply in his sleep, hips jerking up into his hot mouth.

Izuku’s eyes widen when it doesn’t stop, Katsuki thrusting up into his mouth as best he can in the throes of sleep, and the omega just opens his mouth wider and /takes it/.

Because Kacchan is fucking his face right now, even if he’s not aware of it.

“Izuku,” Katsuki groans out, and Izuku’s pussy /gushes/ with slick, wrapping his hand around the base where his mouth can’t reach, working them both up and down simultaneously.

Katsuki just called his name. He just /groaned/ his name in his sleep while he’s getting his dick sucked - and Izuku’s mind is racing at a million miles per hour.

Kacchan wants him back? Kacchan likes him? Kacchan is dreaming of him?

Izuku pulls his mouth off, continuing to jerk the slick dick, eased by his spit as he moves down to draw the alpha’s balls into his mouth, one at a time, swirling his tongue around them and nearly cumming when Katsuki lets out another broken moan.

Izuku will have time to feel like a horrible, shitty human being about this later, because right now, all he’s focused on is filling his mouth with Kacchan’s cum, feeling his knot form at the base and his cock jerk in his throat.

TBC haha porn

Note: gonna make this just one-way somno so it’s not a million parts 😂

Katsuki’s face twists in his sleep, brows furrowed as Izuku moves up to suck his cock back into his mouth, already salivating at the idea of swallowing down his cum.

He closes his eyes in bliss, moaning around the head as he continues to jerk the alpha off at the base, his cheeks wet with hot tears.

“… Izuku?” Comes a deep, raspy, /confused/ voice, and Izuku’s stomach goes cold.

Oh god, oh fuck, here it comes. He’s gonna be thrown across the room, blasted in the face, absolutely beat the fuck up, and he’s just gonna have to take it because he’s a filthy pervert and Kacchan has every right to put him in the ground.

And so Izuku does the thing that he absolutely shouldn’t do, his watery doe eyes blinking innocently up at the blond as he keeps the cock in his mouth, pressing down and wiggling his head back and forth to swallow it down deeper.

“Fuuuuck,” Katsuki groans, deep from his chest, throwing his head back against his plush pillow.

Izuku bobs his head, lips wrapped around the length as he swirls his tongue around it with every pass, and he nearly squeals when Katsuki reaches down to bury a hand in his hair.

“You’re a sick little pervert, aren’t you?” Katsuki grunts, guiding him up and down with a firm hold, his hips twitching as his body finally gets the memo that his cock is being sucked.

“Mmn,” Izuku moans around it, looking up at the alpha like he hung the moon and stars.

“You could’ve just asked, ya know,” Katsuki teases. “Woulda let you suck me off whenever you wanted.”

Izuku rests a hand on Katsuki’s strong thigh, preening when the big hand in his hair strokes gently.

“Why don’t you get up here and sit on my face, hm?” The blond growls, and Izuku nearly cums on the spot.

He pulls off with a gasp, his chin wet and his lips swollen. “Kacchan, I’m so sorr -“

“You’re sorry for sucking my cock?” Katsuki asks with a smirk. “After giving me blue balls with your goddamn teasing for two weeks straight?”

“I wasn’t teasing!” Izuku whines with a pout. “I just wanted you to notice me.”

Katsuki’s face softens. “I’ve noticed you my whole life, shitty nerd.”

Izuku practically feels his heart swelling, his cheeks turning red like he isn’t face-to-face with the cock of the guy he’s been pining after for years.

“Now get up here,” Katsuki demands. “And sit on my fucking face.”

“Kacchan!” Izuku whines. “I don’t wanna, um, hurt you, or suffocate you or something -,”

Katsuki just grunts, sitting up and Yanking Izuku on top of him, manhandling the protesting omega until his panty-clad pussy is hovering over his face, the fabric wet smelling like a feast to the horny alpha.

“There we go,” Katsuki coos tauntingly, pressing down on the back of Izuku’s neck until he gets the memo to take his cock back into his mouth.

Katsuki grins when the omega obediently swallows him back down, moving his hands to flex on the glorious asscheeks in his face.

He pulls the panties down to Izuku’s thighs, revealing his wet, chubby pussy, twitching eagerly when Katsuki’s warm breath hits his lips.

The omega is bent over to suck Katsuki’s cock, opening himself up perfectly as the alpha firmly yanks him back to /sit/ on his face, none of that hovering bullshit, and the blond groans in bliss as buries his face into that glorious pussy.

“Oh my goooo -,” Izuku nearly screams, pulling his mouth from Kacchan’s cock to throw his head back, the blond’s hands holding his hips still as he licks into his slick hole messily.

Katsuki just groans against him, sending these wonderful vibrations straight to his clit, lapping his broad tongue over his slit like he can’t get enough.

“Did I tell you to stop sucking?” Katsuki snarls into his folds, and Izuku’s pussy clenches at his tone.

Eager to please, the omega swallows Katsuki down needily, practically fucking his own face with that fat cock as the tip of Katsuki’s tongue strokes over his sensitive clit.

His hips try to grind against Katsuki’s face, but the blond’s hands on his hips and ass hold him still, forcing him to take everything he gives him.

“Always knew you were a fucking slut beneath that little innocent act you put on,” Katsuki taunts, moving a hand underneath the omega’s hips to play with his pussy. “Just a desperate, cock-hungry little bitch.”

Izuku whines around the length, Katsuki’s hips lazily thrusting his cock up into his throat, the omega swallowing around it eagerly.

“Or is it just my cock?” Katsuki growls, demands, a possessive lilt in his tone.

Izuku hums in agreement, wiggling his head back and forth to take Katsuki deeper, his lips pressed to the base as he swallows him all the way.

“That’s what I thought,” Katsuki chuckles, sealing his lips around Izuku’s clit and /sucking/.

The blond’s chin and chest are soaked with slick, and he can’t find it in himself to give a shit as he slides a finger into Izuku’s wet hole, groaning at the tight clutch.

God, is his cock even gonna fit - ?

One finger becomes two, Izuku’s pussy flexing and clenching around them when the digits stroke his good spots.

Katsuki licks his fingers clean when he pulls them free, sliding his tongue inside to fill the void.

He finally loosens his grip and lets Izuku’s hips move, the omega immediately pushing back and riding his tongue as he presses it in and out.

Uhh tweet limit TBC
