Work Text:
“Are you joining us for movie night tonight?” Ochako hangs down above him, upside down from where he’s lying on the couch. Her hair dangles down, just tickling his nose and he has to try to hold back a sneeze.
“Probably not. Waste of my time. Why?”
“Deku will be there.”
The menacing grin on her cheeks spells danger, and when he catches Mina snickering behind her, knows no good can come of this combination. He drops his phone to his stomach, eyes narrowed to slits, and raises an eyebrow.
“What are you two up to now?”
“Oh nothing!” Mina jumps over the couch to land on top of him and he rasps, pretending to die from lack of oxygen.
“This is it. This is the end of me. This is how I die. I’m being crushed by the fattest ass in existence. When I finally go, someone burn my body in the coolest explosion of fireworks and-”
“Oh shut it, explodey!” Mina smacks his chest, “I am not that heavy! You’ve literally carried me before!”
“Not the same thing!” He argues.
“Okay, Deku’s done this before! Multiple times! Jumping from higher up! I once saw him drop from 10 feet up onto you, Kats.” Mina pouts.
Ochako’s grin seems to get more devious, if possible, and Katsuki fears for his life, “So what. Your ass has its own gravitational pull.”
“You let Deku do whatever he wants and don’t say shit. Last week I saw Deku carry you out of the dorms and instead of arguing, you just. Pulled out your phone and started texting.” Mina snarks.
Ochako looks at Mina, “Who was he texting?”
“Kirishima. Something about how he wanted to suffocate himself in Deku’s bubble butt and be choked out by his beefy arms.” She leans down, “All while discreetly taking pictures of Deku’s ass while hanging upside down.”
That shuts him up.
“What movie and how long do I have to stay?”
Of course the movie choice ends up being horror; Deku hates horror. It’s both a curse and a blessing to Katsuki when Deku curls up on the couch next to him, bundling both himself and Katsuki in what seems to be the biggest comforter he could find.
To Katsuki’s relief, the comforter only has All Might’s colors scheme. Katsuki would lose his mind if he had to glimpse his own teacher’s face in between flashes of light from the movie. As much as an All Might nerd as he’s always been, seeing the man’s face on Izuku’s bedding unsettled him for other reasons. Embarrassing ones. He felt the same way about the figures in Izuku’s room.
It’s hard to fantasize about getting intimate with Izuku with the face of All Might a foot away. It made him want to shrink into himself, humiliated by being caught red-handed even if it was just by a sewn picture.
Katsuki absolutely does not squeak as Izuku presses into his side when Iida turns the lights out. Katsuki knows, from years of experience, Izuku always does this. Nothing would change if Izuku sat next to Round Face, or Pikachu, or even Pinky over there. Out of everyone, though, including Izuku’s closest friends, Izuku chose Katsuki.
It makes Katsuki’s cold, little heart grow three sizes like the goddamn grinch.
Katsuki wears a loose black tank top and sweats as usual, while Deku dresses like the straightest boy Katsuki’s ever seen. Snow falls to the ground out the windows behind them, but Izuku still wears basketball shorts year round like it's summer just like in middle school, and his t–shirt says “MILF: man I love frogs” with a picture of a frog. It’s tacky. Katsuki loves it.
Izuku wore those “shirt” shirts so often, 1A started gifting him a slew of other ridiculous meme shirts, Mina and Kaminari having the most fun out of the group, and Izuku cherished those stupid things. He wore them every day. Katsuki didn’t think Izuku could ever have any more insane shirts, and then Izuku surprises him with something else wacky from his closet. Katsuki prays he doesn’t own animal prints. He can handle horrible meme shirts. Animal print? He’d have to disown Izuku for life. If Katsuki looks hard enough, he swears he can see the outline of Deku's dick in his grey basketball shorts. God is real.
Deku grips his arm like a lifeline before the movie even starts. The girls picked some kind of shitty slasher film, the kind that makes Deku squirm, and inside he preens a little because he knows why. He’ll have to treat them to dinner for being wing-women, or something.
Deku squirms next to him and Katsuki has to debate between his heart’s desire to curl up next to Deku and his anxiety’s need to want to run and hide underneath his bed like a frightened cat. Deku’s so warm, body pressed against him, shirt riding up just enough for a sliver of skin to touch Katsuki’s bare arm resting between them.
Another crash comes from the movie, the rest of the group screaming, Deku included, and Katsuki takes his chance to suck it up and he curls his arm around Deku’s waist, fingers pressing into Deku’s side like a reminder. As if to say, “I’m here; you’re safe."
Katsuki’s thumb rubs soft, soothing circles on Deku’s hipbone and Deku looks up at Katsuki, nervous, questioning, before throwing his legs over Katsuki’s. The blanket covers them both, and no one notices the two cuddle up to each other. Katsuki knows the girls suspect something, but by now, everyone pays far more attention to the movie and treats than anything else.
Katsuki uses his other hand to pull the blanket up to both of their chins, burrowing them both in the way they used to during All Might movie marathons, and Deku shoves his face in Katsuki’s neck as the murderer on screen cleaves someone in two. He whimpers; the vibration gives Katsuki goosebumps all down his arms.
Deku fidgets a little in Katsuki’s lap, his ass pressed against Katsuki’s crotch. Deku doesn’t look up from Katsuki’s neck, so he can’t be sure the move is on purpose or not, most likely not, but Katsuki tries to keep his cool.
It’s just a movie, dude. You can’t get a boner with your friend in your lap. Now is absolutely not the time to get turned on.
Only that makes it worse, and Katsuki feels his cock twitch in his sweats. He prays Deku doesn’t notice, and he keeps his eyes on the screen, refusing to look anywhere near Deku.
Deku wraps his arms around Katsuki’s back, low, rubbing his nails against him and well, that absolutely doesn’t help Katsuki’s situation at all. He knows for sure Deku fidgets.
He’s seen Deku play with Ochako’s fingers during movies, and braid Tsyuyu’s hair during study sessions. Deku’s absent-mindedly crawled over Todoroki to get closer to someone on the other side of the couch instead of getting up; Katsuki knows he has no boundaries regarding physical touching. Deku’s been like this since they were kids.
This feels. Different. Deku’s hands wander lower on Katsuki’s back, gliding close to his waistband, only to go back up, pulling Katsuki’s tank top up with it, only to drop it back down. His nails dig in, almost like a massage, and it sends sweet tingles down Katsuki’s spine. He never wants him to stop.
Deku finally, finally, drags his hands down Katsuki’s spine, pressing down on every individual vertebrae, and once at the bottom by his waistband once more, dip just slightly inside enough to play with Katsuki’s waistband. He runs his fingers along it, calloused fingers just barely brushing Katsuki’s heated skin. They wander once more, towards Katsuki’s front, and he urges to move his hips just a little and begs Deku’s thinking what he’s thinking.
A soft kiss presses just beneath Katsuki’s ear, “Stop me if this is too far,”
Deku sounds huskier, raspier than Katsuki’s ever heard him and he wants him to never stop talking.
By now, Katsuki’s embarrassingly hard. Deku can absolutely feel his cock pressed against him by now, and Katsuki bites his lip to keep from whimpering when Deku shifts in his lap, adjusting slightly. He’s no longer pressed against Katsuki’s crotch, not entirely, and Katsuki squeezes his eyes shut as Deku’s hand slips into his sweats, under his underwear, and takes out Katsuki’s cock.
Holy fuck, holy fuck, holy fuck. Is he really doing what Katsuki thinks he’s doing? Are they really doing this? With all of their classmates a few feet away?
His chest pounds like a drum as he finally manages to peek at Deku, who has a sneaky grin on his face as he starts to stroke Katsuki’s thick cock, starting off slow. He always knew Deku was a freak but he didn’t expect this sort of a freak. Deku twists his fist, making Katsuki jerk, and it’s almost pathetic how aroused this makes Katsuki.
Katsuki thrusts his hips up into Deku’s fist, his half-lidded eyes not leaving Deku’s. It’s not long before he’s fucking into Deku’s fist more than anything. Deku presses his lips to the underside of Katsuki’s jaw, making his way down Katsuki’s neck to collarbone with meticulous butterfly soft kisses.
Katsuki isn’t sure if he prefers this or if he’d rather Deku go rough, but he knows he’s tempted to drag Deku upstairs to one of their dorm rooms, but that would attract attention, and he can’t exactly drag Deku out of the room with a raging hard-on, now can he?
The pleasure builds inside of him; he won’t last long, he knows, and his labored breathing clearly shows. Katsuki’s eyes flutter, and Deku’s lips press to his ear once more, breathing soft against his sensitive earlobe. “I can feel how close you are, Kacchan. Should I let you come? Or maybe I’ll leave you to squirm a little for me.”
Deku, that little bastard. Katsuki doesn’t beg. He never will but, oh, is he tempted to, as he rams his hips harder into Deku, silently scanning his eyes across the room to assure himself no one’s looking away from the screen. They aren’t.
“Fuck you, nerd.”
“That can be arranged, but now really isn’t the place for that.” Deku nips at his ear, huffing out a laugh, “Say please.”
“Please go fuck yourself.”
The hand stroking his cock comes to a stop, and Katsuki’s hips jolt, the warm feeling in his belly starting to twist inside him, curling and churning, begging for release. He wants it. He needs it. He aches like if he doesn’t release this thing building up inside him, he might burn up from the inside out. But he won’t stoop so low as to beg for it. Not from anyone, and especially not from Deku.
“Should I stop then?” He strokes once more, slowly, “Or keep going? There’s only so much time.”
It’s the swipe of Deku’s thumb under the head of his cock that does it, makes Katsuki’s eyes roll up into the back of his head and he finally turns his head towards Deku, out of breath when he pleads, “Fuck, Deku, please.”
Impish, Deku ducks under the blanket. To any outsider, it looks like he fell asleep burrowed under the comforter. However, as Katsuki learns, moments later, feeling a huff of breath on his cock, Deku has different ideas.
Katsuki doesn’t look under the comforter, far too nervous to watch, and also because he may actually combust, as Deku licks a slow strip down the bottom of Katsuki’s cock. He has to stop himself from moaning out loud, Deku’s tongue warming him from head to toe.
Katsuki’s glad the class bought that surround sound system last year because it blares loud enough to mask any noises Deku may make underneath the comforter, and any accidental ones that may slip from Katsuki’s tongue, unbidden. The couches have enough separation between them that no one can hear anything anyway.
Deku swirls his tongue around Katsuki’s cockhead and Katsuki wonders where on Earth Deku learned how to do this. He hopes Deku hasn’t been practicing on anyone else in their class; maybe Deku’s just unnaturally amazing at giving blowjobs like he excels in everything else.
Deku perfects everything he tries; it always infuriates Katsuki to no end. Katsuki spent most of their childhood practicing in secret to make sure any move with his quirk looked perfect when he showed it off. Deku, without a quirk, amazes everyone without even trying. Deku, shows off his A+ in math. Deku manages to put together a functioning volcano project with actual lava and wins the science fair. Which, until the day he dies, Katsuki will never admit, is the coolest thing he’s ever seen and he’s still furious to this day about it.
A breath catches in his throat as Deku takes Katsuki’s cock in his mouth. Deku grasps Katsuki’s hip now with one hand to press down, keeping him in place, as Deku starts to bob his head.
Katsuki might die. Someone should call for a hearse and priest because today, his heart may as well sputter out like a dying car engine with how Katsuki’s legs tremble beneath him. He grips Deku’s hair in one hand to keep himself stable, while the other remains tight on Deku’s hipbone, most likely leaving moon-shaped imprints to match Deku’s constellations of freckles.
Just as Katsuki thinks he needs to start deciding who speaks at the pulpit for his funeral and who carries his casket, Deku hollows his mouth and sucks.
Katsuki thinks Deku just masquerades as a human, when really, he has to be an incubus. Deku may as well be sucking Katsuki’s soul straight out of his cock, and Katsuki thinks he may end up shriveled like a raisin at the end of this. He wouldn’t be too mad about that.
“Fuck, Deku!” Katsuki whispers, grasping a handful of Deku’s messy curls in hand, accidentally pulling them and making Deku moan. The sound vibrates around Katsuki’s cock, making him arch his back into the couch.
He really, really hopes no one notices, because he’s not too sure he could stop now if he tried. The temptation to fuck Deku’s mouth? Real. However, he doesn’t want to make too much noise, or make him gag, so that’s put on the to-do list for another day, if this ends up being a repeat. He prays it is.
He also hopes this whole thing ends up with him having a boyfriend, but Katsuki doesn’t have a way with words, and he’s too chicken-shit to ask, even though Deku currently has Katsuki’s cock in his mouth.
Katsuki thinks he died and went to heaven, because Deku’s nose brushes Katsuki’s pelvis, and how did he even manage that? Katsuki tugs again on Deku’s hair, this time intentionally. He loves Deku’s soft locks in his grasp if only he could feel them more often, preferably in a more intimate setting. Yeah, they share a dorm at night for, you know, “platonic snuggling,” well not so platonic on Katsuki’s end and on Deku’s, who knows, but running your hand through your bro’s hair usually throws up a few red flags and sirens. The cuddling in itself already would leave any normal person with questions, so their nighttime snuggling? Just another secret.
Heat coils in Katsuki’s abdomen, and his toes curl, breath quickening. He gives Deku’s hair a tug to attempt to pull him off, whimpering; a warning of sorts, as best as his brain can come up with. Deku resists, but raises a hand to hold on top of the one in his hair, pulling at it as if to say: harder.
Oh.
Katsuki’s eyes roll up into the back of his head, a shiver runs down his spine and his vision goes white. He comes down from his high, breathing heavily. Oh. Well. That happened.
Deku emerges from under the blanket, licking his lips with a sneaky smirk on his face, and curls back up against Katsuki to watch the movie again like nothing happened.
Katsuki still can’t breathe, especially with Deku cuddled up against him again with arms wrapped around him again and nose pressed into Katsuki’s sensitive neck all over again. Katsuki wonders if he dreamt the last few minutes, but he shifts and, nope, that. That happened.
The movie wraps up, as lame as Katsuki thought, even if he missed a handful of it while distracted by Deku’s mouth, and everyone slowly trickles out one by one, until it's just him and Deku left.
“So, bed?” Deku asks.
Absolutely casual, the most coolest, relaxed guy ever, and not freaking out at all, Katsuki grabs the massive comforter up in his arms, and follows Deku upstairs.
