CW: a/b/o, dubcon

O!Kirishima thinks it'll be hilarious to prank his alpha roommate, so he unzips Bakugou's body pillow cover and puts the pillow under the bed. He wraps himself in bubble wrap, inserts himself into the cover, zips it closed, and waits, giggling. This'll be fun!

Several hours--and orgasms--later, Bakugou can't understand why his rut was triggered early or why he keeps humping his lumpy body pillow. The pillow /smells/ like an omega wet with desire, and he /WANTS/ it. So he fucks his aching, weeping erection across the pillow, moaning.

After his tenth orgasm, Bakugou rolls off his body pillow. He sniffs the air, mind hazy with lust and the scent of heat-drenched omega. He rubs his neck all over the pillow, dragging his hands across it. When he tries to drag it closer, he's thrown off by how /heavy/ it is.

He tugs again. Yeah, it's definitely heavier. And...is that a whimper? He grunts and rolls back on top of it, ignoring the pool of cum cooling across the middle. Slowly, he unzips the pillowcase.

When he pulls it back, he gawks. A thick wave of omega in heat hits him, and there+

right beneath him and between his thighs, is none other than Kirishima, his fucking roommate.

The omega gazes up at him with lust-hazy eyes, his parted lips shiney with drool. He makes another soft sound, lifting his hips--still trapped by the pillowcase--and begging to be bred.

Bakugou's alpha /ROARS/ at him. This is the omega he's been craving for /years/. He wants nothing more than Kirishima on his hands and knees, ass in the air, wet with slick as he presents himself for breeding.

It takes everything Bakugou has to slide off Kirishima's hips.

It takes even more willpower to step away from the bed. His dick bounces as he moves, hard again already. Heat surges through his blood. His alpha chants, /Omega, omega, omega,/ the word turning to a three-beat rhythm in his mind. /Breed, breed, breed,/ follows.

He burns for it.

His blood boils with feral, raw need, and he almost steps forward again.

Kirishima wriggles against the pillowcase and--hold the fuck on. /Is that fucking bubble wrap?!/

It doesn't last long. Seeing his potential mate bound sends Bakugou over the edge. He slashes the bubble +

wrap to ribbons before stumbling away again, chest heaving. Sweat drips down his temples. His skin is clammy, and his abs shake with the strain of fighting his urge to pin Kirishima down and mate with him. God, he wants to. If he could just...just pin him...it would be okay.

He has to hold on. He can't just...just go /feral/, even though his alpha is taking over. Fuck.

His cock's throbbing, and the base is swelling.

A soft whine catches his attention.

Bakugou lifts his gaze in time to see Kirishima roll slowly to the left. He gets on his hands +

and knees, and slowly, oh so slowly, he lifts his plush, pink ass into the air. Slick glistens around his asshole, a few drops sliding down his balls and inner thighs.

Fuck.

Fuck, fuck, FUCK.

He's presenting, just like Bakugou always dreamed he would.

Bakugou's thread snaps.

He barely registers what happens next. All he knows is that his tongue is somewhere tight and hot, somewhere that tastes like the sweetest honey he's ever had. He shoves his tongue deeper, desperate to get more. His fingers dig into plush cheeks as he pulls them apart.

He dives deeper, sucking and licking, chest heaving. His logical mind us gone. All that's left is the pounding need pulsing through his cock, swelling hot in his balls.

This isn't enough. It's not even remotely enough!

MORE. He needs MORE!

He pulls his mouth away and shoves Kirishima forward far enough to straddle his legs. He rubs his swollen cockhead over his omega's opening. Slick wets it, soaking his cock. A few pumps has him sopping, and he lines himself up, eyes rolling back as he pushes in the first inch.

The head of his cock pops past Kirishima's rim, and Bakugou is assaulted by the sudden tight, wet heat of the omega's delicious ass. Bakugou's nails dig into Kirishima's hips as he pushes deeper and deeper, mouth gnashing wordlessly as heat surrounds him.

Holy /fuck/.

Why hasn't anyone told him mating feels so fucking /good/?

He finally bottoms out, his swelling knot popping in just before locking them together.

Beneath his palms the omega trembles. His ass clenches around Bakugou, and he whines, begging without words for more, for movement.

Bakugou's more than willing to give his omega everything he can. Sure, he can't pull out all the way--his thick knot attests to that--but he can fuck deeper, and he can stroke his omega's cocklet.

Kirishima's dick is leaking into Bakugou's bed, and something primal in Bakugou +

rumbles in pleasure. Good. He likes that /his/ omega is making his bed smell like him, like the earth and seaside and honey.

Bakugou humps forward again and again, focusing on using his knot to stimulate Kirishima's prostate. Every grind has his omega gasping and shaking.

"Gonna...gonna c-cum...please, alpha. Please, god, please..."

His words slide together, turning into a single, nonsensical whimper as Bakugou speeds up. Thwapping echoes as his naked hips slap against that pert, punk ass.

Bakugou slaps it, leaving a brisk, red handprint.

Fuck yes. Fuck /yes/. He's so close, and with the amount of begging and precum coming out of Kirishima, he must be, too.

Bakugou bares his long claiming teeth, ready to scruff his mate and bite him, claim him, during orgasm. His instincts guide him. Pleasure books and builds,+

and with it, his desire to /claim/, to own.

Heat burns down his spines and to his toes before shipping back up to pool just above his balls. He yanks Kirishima back, teeth poised. Faster. Harder. Begging. Whimpering. Neediness.

Heat blows through him.

Bakugou bites down.

He groans as he fills Kirishima with pump after pump of cum. Wetness coats the hand he has wrapped around Kirishima's cocklet.

The heat turns to something sweet and calming, and Bakugou licks at the bite while tenderly lowering his mate to the mattress.

Within seconds, Kirishima's snoring.

Bakugou huffs a soft laugh and kisses his temple.

They'll talk when his mate wakes up. For now, he loops his arms around Kirishima and buries his face against the back of his sweaty neck. He inhales his omega's scent and sighs.

/Guess I don't need a body pillow anymore./

No, he has something so much better.

He has a mate.
