Deku doesn’t quite understand it, but he’s past trying to. It’s just a habit now. When they all get together for movie nights, seating is sparse.

Ochako sprawls across Mina and Kirishima, Kami sits on Shinsou, and Deku settles atop Kacchan. https://twitter.com/kaacchaann/status/1339737594234605568
((a/n: just a little thread. an itty bitty thread. tiiiiiiny little thread. 😌))

(CW: Deku’s got a pussy; slight exhibitionism; fondling/groping; maybe some fingering? idk im writing this as i go LMAO)
The others sometimes switch around, but Deku ALWAYS sits on Kacchan. It’s just more convenient that way. He doesn’t pay attention to it, really...

...except last week, when Denki had waggled his brows and hollered, “sit that dumptruck on me tonight, Midoriya!”
Deku flushed at the explicit compliment—at least he’s pretty sure it was meant as a compliment, judging by Kami’s grin—but he didn’t even have a chance to reply.

Kacchan simply curled his big, strong arm around Deku’s middle, and tugged him backwards, onto his lap.
“Fat chance, Forty-watt.” Is all Kacchan said before putting his other hand around Deku’s waist, pulling them flush together as the movie started.

Deku felt his cunt flutter at that hint of possessiveness and when he got back to his room, he was so wet he’d almost leaked
through his underwear.

It’s been an entire week, and he’s still thinking about it.
Tonight’s movie is a thriller—some kind of horror film that Deku had NOT voted for in the weekly poll—so he doesn’t even consider sitting anywhere but on Kacchan, even if he’s nervous about it.

He’s thought long and hard, and has decided to take preventive measures.
For starters, he wore thicker pants.

Tonight he wore sweatpants, quite thick compared to the thin workout leggings he normally wore.

Secondly, he brought his All Might blanket with him—he would wrap it around himself to create even more of a barrier between them.
But that all went out the window when he joined Kacchan on the couch.

“The fuck, are you cold?” is what he askes, glaring quizzically at the sweats and the blanket. “You’re gonna
boil; you know I run hot.”

“Cold. Yeah—M’just cold.” he says, tugging the blanket around himself.

“Deku, don’t be a dumbass—you’re gonna get all sweaty. Ditch the blanket, you know I’ll keep you warm.”

“I don’t want to—“

Kacchan sighs, and yanks the loud-colored fleece
away from Deku’s shoulders, tugs him down against his lap, and drapes it over their legs.

“Fine, see if I care when you fucking dehydrate yourself.”

One arm-chair over, Kirishima chuckles, pulling Kami close to his chest.
The movie starts, and Deku gets really into the first few scenes. The set up is interesting—he’s so into the plot.

Until the actual scary shit starts.

He’d been steadily inching forward, barely seated on Katsuki’s knees, before a jump-scare sends him scurrying backwards.
Kacchan’s there, though—arms around him instantly, steady hum in his ear.

The class’s gasps taper off into startled laughter as he and Katsuki lock eyes in the glow of the projector.

“Sorry,” Deku whispers.

Those eyes trace his face and stop at his lips. Deku’s pussy
flutters again, and Kacchan smiles.

“Mhm.” He hums, and Deku snaps back around, stiff as a board.

He can do this—they’re about a third of the way through the film, he can make it to the end without embarrassing himself, surely.
But then Kacchan’s tugging him backwards again, Deku’s back to his chest, and when Deku doesn’t sag, he whispers, “Would you relax?”

“It’s scary.” Deku mumbles.

“Then don’t watch.” He mumbles back, and one of his hands on Deku’s waist slip under his waistband.
Deku eeps, fumbling to spread the blanket out over his crotch, where Katsuki’s big hand is CLEARLY moving.

Over his boxers, Katsuki’s whole palm cups Deku’s cunt, and he curses quietly at how damp and sticky it is—he can feel it THROUGH the fabric.
It doesn’t take much longer for Kacchan’s cock to start stirring between them, making Deku clench down again.

Kacchan presses his lips to Deku’s neck to stifle his groan.

Feeling him through pants is one thing—his chubby cunt twitching against his fucking palm is another.
He quickly tugs the tight fabric to the side, holding it open while he slips his thick pointer finger through sticky folds.

Deku has to cover his mouth, and as Kacchan explores his pussy, neither of them notice the film’s score picking up, or their peers leaning
forward—until the scene ends in another jump-scare, popping the tension in the room with another set of frightened gasps and squeals.

Kacchan’s hand stills for a moment while their friends all look around, giggling to eachother about it being a good movie.
Screw the movie, Deku thinks, because Kacchan’s—he’s—

“Ah,” He barely sighs, because Kacchan’s fingers tear at his underwear at the next burst of sound from the screen, exposing his entire cunt to those delicious fingers. “Kacchan,” He whisper-shouts, “Someone will see—“
And Kacchan tries to whisper back, but his voice is just too deep—it’s still rumbly.

“Is this why you wore all these clothes? Because sitting on my lap makes you wet?”

Deku gasps, scandalized, and looks around to see if anyone noticed.
He’s so sticky, Deku can almost hear the way Kacchan’s fingers slide over the puffy lips, and when they press hard enough to clip his clit, he has to bite his tongue.

“Fuck, I bet you’re so pretty here.” Kacchan grumbles, pinching at Deku’s little clit. “Does that feel good?”
Deku nods hard, his legs unconsciously spreading.

It’s not his fault—he hardly even does this to himself, okay? He’s weak to the pleasure, and fuck, it being KACCHAN giving it to him makes it even worse!

For a second, Deku’s scared to cum; he isn’t sure he’ll be able to keep
quiet—but then Kacchan is slowing down, then picking up again as their peers start clinging to eachother in anticipation, as the score builds up again.

Tension in the room and on the screen stretches taught as a drawn bowstring, and in the rapid percussion of the chase scene,
Kacchan takes four fingers—rubbing them harshly through Deku’s chubby cunt, bumping his clit each time—at just the right time.

Deku can’t help the rapid, high breaths he lets out, or how he lifts his feet up to Kacchan’s knees to lean into his touch—but it’s okay, because
Kacchan’s timed it perfectly.

Deku cums right as the climax of the scene. When all their peers scream in fear—Deku yelps in pleasure.

He sags against Kacchan, legs twitchy as Kat lowers them to the floor, pressing a little kiss to his temple, humming. “Hm. Cute.”
Without even saying another thing, Kacchan just cups Deku’s sex one last time, before pulling his hand out and immediately dragging it up towards his mouth.

“N-no,” Deku whimpers, grabbing his wrist.

“Why not? I made you cum. Don’t I get to taste it?”
Deku covers his face—in equal parts shame and renewed arousal—as Kacchan licks his fingers clean.

A few more scenes go by; the film’s story is wrapped up semi-neatly, leaving just enough undone for a sequel, and then the credits are rolling and the lights flick back on.
Deku tries to stand, but Kacchan keeps him firmly seated.

He doesn’t understand at first, until Katsuki shifts the blanket some, so Deku can see the huge damp patch in his sweats, and Kacchan’s lap.

He yelps, mortified, but Kacchan only laughs.
