he looks up, catches sight of bakugou's ass in gray sweatpants, and his dick kind of. tingles.
and when he takes the next step he /feels/ it, like he's rubbing against himself and the front of his underwear just by moving, and there's that tingly feeling again.
it's subtle, and nice, and a little weird, and kirishima looks up again when bakugou says something about
it's subtle, and nice, and a little weird, and kirishima looks up again when bakugou says something about
hurrying up and yup, there's his ass again.
it takes another few steps before kirishima's brain catches up with him.
"um, babe?"
"yeah?" bakugou says, looks back over his shoulder and raises an eyebrow when he sees kirishima staring at his ass.

"I think I have a boner," kirishima says, and /that's/ when his heart starts pounding away in his chest, /that's/ when it dawns on him that yeah, his dick is twitching and swelling and he's warm and bakugou's ass looks fucking great and he can physically /feel it/.
"yeah?" bakugou says, softer and with a sharp, happy smile, and kirishima nods, tries not to brokenly laugh with how big and fluttery he feels.
"wanna do something about that?" bakugou asks, turns to face him, eyes him from head to toe.

"um," kirishima tries, and he's so happy that he's tearing up and it's silly, it's ridiculous, and he's so /happy/.
"I kinda wanna just- feel it? for now?"
bakugou nods, hums, bends over to kiss him on the cheek.

"take your time," bakugou tells him before he turns around and starts going up the stairs again, and kirishima gives himself a moment to feel like he's floating away before he follows.
it stops somewhere between one class and the next and while kirishima rides the emotional high for the rest of the day, he kind of forgets about it until later that night.
he's sat on the bed with his arm over bakugou's shoulders. some movie plays on the tv and bakugou rests his hand on kirishima's thigh, squeezing whenever kirishima nuzzles into his hair.
it's calm, quiet, cozy, and then bakugou starts sliding his hand up and down kirishima's thigh and he feels his dick twitch before that tingly feeling comes back again.
he doesn't say anything, just silently enjoys experiencing how his body reacts.

but then bakugou starts rubbing his thumb into the meat of his thigh, fingers reaching out on the inside of it, and kirishima breathes out hard through his nose. he spreads his legs, just a little bit, and his swollen dick rubs against the fabric of his underwear.
he knew he'd get bottom growth, of course, but. he's been busy with classes and training, hasn't had time to keep up with his body, and now it's like he's finding out about himself for the first time.
and it's.
god, it's exhilarating. it's /right/.
and it's.

bakugou hums quietly, noticing kirishima's shortness of breath and how he sinks into the bed.
"feel good?" he asks, turns to nuzzle into the crook of kirishima's neck.
"yeah," kirishima says, dick hard and chest full of butterflies.

"c'mere," bakugou urges, lifts his hand to angle kirishima down with a finger to his chin. kirishima goes, kisses him, and bakugou goes back to squeezing and rubbing at his leg.
bakugou sighs into his mouth and slides their tongues together at the same time as kirishima

feels himself twitch again. he can't help the tiny, breathy sound he makes, and bakugou digs his nails into his thigh, a silent curse while his mouth is busy.
kirishima closes and spreads his legs and his dick rubs against fabric and himself every time he does and he feels so very warm, so very full of giddy happiness and molten arousal.
bakugou breaks the kiss and pecks him on his cheek, his jaw, down the side of his neck.

kirishima swallows thickly, moves his arm from bakugou's shoulders to around his waist, instead.
"I'm," he tries, and he feels like laughing, or crying, or fucking. or all of them. "I'm hard, katsuki. I'm /hard/."
"I'm," he tries, and he feels like laughing, or crying, or fucking. or all of them. "I'm hard, katsuki. I'm /hard/."
he says it with a silly kind of wonder, like he can't quite believe it, but.
he can feel it in a way he never could before. he can /feel/ how his dick is big enough to poke out from him instead of hiding too close to his body.

it's surreal in the way that he's wished for it for so long and real in the way that he feels like this is, finally, his body. it's his. it's the way it's supposed to be. it's /his/.
"katsuki," kirishima says, smiling so wide it hurts and with tears in his eyes,

and bakugou straightens up to look at him.
the worry in his eyes disappear when he does, eyes warm and here and /seeing/ him.
"yeah? how's it feel?" he murmurs, and it both sounds and feels like the crackling of a fireplace.

"good," kirishima says, nodding. "like myself."
"mmh," bakugou breathes as he leans in to press their foreheads together. kirishima wraps both arms around him, hugs him close.

"wanna just feel it for now?" bakugou asks, and.
god, kirishima loves him.
"I wanna, um," kirishima starts, clears his throat. "will you suck me?"
bakugou looks at him like he's searching for something for a few seconds, but then he sits back, grabs kirishima's hands.

he brings them to his mouth and kisses them, breathing in hard, eyelashes fluttering when he squeezes his eyes shut. then, he bites the pad of kirishima's thumb, gently and playful, and drops his hands.
"fuck yes I will," he says, and kirishima hears 'I love you too'.
