#nsfw college!omigiri cw: breeding kink

osamu's dick hits just right and kiyoomi groans into the mattress, pillowcase between his teeth. his phone rings and he reaches to silence the noise but osamu smacks the back of his hand and picks it up himself, thrusts never faltering.

"toya. 'sup?" osamu grunts, tucking the phone against his ear so he can cage kiyoomi on the bed and grind his full length all the way in, /deep./

kiyoomi mewls desperately, back arched and shuddering under him.

"yeah..." osamu sighs into kiyo's neck. "he can't talk right now."

osamu circles his hips and kiyoomi's hands clench into the blankets, whines muffled by the pillowcase.

"crammin' for a test," osamu grins, snapping his hips in successive shallow thrusts. "been at it fer hours now, think he's prob'ly almost there..."

kiyoomi's gasping moans increase in volume, knuckles white where they grip the bedspread.

"sure, i'll tell 'im to call ya when he's had his fill. laters." osamu hangs up and tosses the phone out of the way, then adjusts his position for better leverage, fitting his hands around

kiyoomi's supple waist, so narrow compared to the width of his back and shoulders.

he slowly pulls out and then rams back in, punching a lewd cry from kiyoomi's lips. the pillowcase falls from his lips, damp with his drool.

"/more.../" kiyoomi exhales between thrusts.

"hell yeah," osamu replies, hands sliding down to kiyoomi's belly and rubbing where his dick causes a subtle bulge. "gonna cram ya full an' make sure it takes."

kiyoomi nods, pliant in osamu's hands while his thighs flex, bracing against the impact of each jolting thrust.

"gonna be so cute carryin' our little one," osamu croons, massaging kiyoomi's abs.

kiyoomi nods, then shakes his head. he holds up two fingers in a peace sign. osamu frowns, not following. kiyoomi shows him the peace sign more insistently.

"kiyo?" he asks, slowing down.

kiyoomi huffs, turning his head enough to meet osamu's gaze, pupils blown wide. he stutters through osamu's steady rhythm, "you're gonna... breed me... with /twins/... right?"

osamu inhales sharply.

oh.

oh /fuck yes./

"goddamn," osamu rasps, throat dry and balls tightening between his legs at the thought of kiyoomi heavy with a pair of his offspring, plump and utterly delectable. "yer goddamn right."

osamu bends to plant kisses on kiyoomi's back before hauling him upright, straddling his lap.

kiyoomi keens, osamu's palms on his pecs keeping him balanced so osamu can fuck into him hard and fast, bouncing him without mercy.

"gonna fill ya up so full yer gonna pass every last test," osamu promises, sweat beading his brow from the sheer physicality of their joining.

"yes, yes, yes..." kiyoomi chants, dropping his weight onto osamu's thick cock to match his efforts.

they're both sticky from the previous rounds, and it's not long before osamu's ready to deliver another load into kiyoomi's tight, perfect ass.

"ready?" osamu husks.

kiyoomi shivers. "hurry" he urges, hand falling to his dick and jerking it. "knock me up, samu!"

osamu grits his teeth and plows his cock so deep kiyoomi cries out, coming all over the bed. osamu pulls kiyoomi down hard onto his dick and holds him still, letting him clench

through his aftershocks before he shoots more white-hot ropes of come inside him, groaning and panting through his climax.

when their twitching subsides, osamu eases them onto their sides, still buried in kiyoomi while they catch their breath. kiyoomi lets out a deep, satisfied

sigh, but taps his fist to his forehead.

"/whyyy/ is it so hot to... /pretend/?" he asks.

"what, the breedin' stuff?"

kiyoomi tsks, like he does when he's embarrassed.

osamu chuckles. "maybe 'cuz yer completely bonkers fer me."

"oh please," kiyoomi scoffs,

lips twitching in mirth.

"fine, yer just a raging kinky perv then," osamu grins. he also dodges kiyoomi's elbow.

"you're the one obsessed with the dirty talk," kiyoomi complains.

"an' just who was it that begged 'breed me with twins'?" osamu retorts. he dodges the elbow again.

"shut up," kiyoomi snaps, the both of them chuckling. he takes osamu's hand and puts it on his belly. "just lie here a bit and be quiet. i don't want to move."

osamu kisses his shoulder, then his neck, then the back of his ear. "anythin' for ya, kiyo."

kiyoomi laces their fingers and sighs. "they'd better take after me," he comments, lips twitching again.

"now that's somethin' we can agree on," osamu laughs, ruffling kiyoomi's damp curls and squeezing him tight.

✌️💞🍙😷

omake: after they shower and clean up, osamu produces a pregnancy test, and hands it to him, sparkling. kiyoomi gives him the most disgusted look until osamu puts it in a drawer out of sight.

it doesn't stop them from "trying" again two hours later.
