Bkdk YouTube/let’s player AU tho. Deku’s sweet and good natured and mostly plays for fun. Meanwhile, kacchan is... kacchan, basically. He yells and screams and plays to win, but loves a challenge, so they play against each other often.

Oh, and everyone thinks they’re fucking

Or at least, if they arent already fucking, everybody wishes they were, bc the sexual tension is off the goddamn charts. At first, kacchan used to just scream at deku all the time, like he does with anyone else. He still does sometimes, but eventually they found their own rhythm.

And it’s flirtatious as fuck. Deku’s all, “catch me if you can, kacchan,” and Kacchan in turn replies with suggestive remarks about “destroying Deku’s ass” or something lol. The chat flips shit every time that happens, but they both refuse to acknowledge it.

Until one day, they do. They do a stream together, in person, both sitting on a couch, answering questions, and someone inevitably asks what their relationship is. Kacchan rolls his eyes. “For fuckssake, we’re just /friends/, okay? We’re rivals.”

“I don’t know how you fuckers got it in your head that we were anything more, but that’s how it is.”
“Yeah,” Deku chimes in. “It’s great that you guys have such, err... vivid imaginations, but... that’s. That’s all it is, really. Your imagination.”
The stream ends shortly after.

Or at least... that’s what they thought. They both said bye, deku tried to end it, but without either of them realizing it, it kept going. Deku stood up, yawned, told kacchan, “I’m gonna get something to drink. Want anything?”
“Nah, I’m good.” He said, and deku walked away.

At this point, most people in the chat were just. Confused, like, uhhh... guys???
When deku came back, kacchan was lying down, taking up the whole couch.
“Kacchan, sit up,” he sighed.
“Mm, no.” He replied sleepily.”
“I wanna sit down, though.”
“Sounds like a ‘you’ problem.”

“Don’t make me tickle you.”
Kacchan opened his eyes a bit, scowling. “You wouldn’t.”
“You know I would.”
“Just go sit on the chair or something.”
Deku set his drink down.
“Well, you leave me no choice, then.”
Suddenly, he pounced, leaning over to attack kacchan’s sides.

Kacchan started laughing uncontrollably, swatting at Deku’s hands. The chat’s already going wild, but when deku actually moves to straddle kacchan’s hips as he’s tickling him, the insanity just reaches a whole new level. Kacchan’s laughing, but catches Deku’s wrists soon enough.

And what happens next is something they cant go back from. All at once, kacchan sits up, catches deku off guard as he uses his hold on his wrists to force him onto his back, effectively flipping their positions placing him right between his legs.
“Fuckin playin with fire, deku.”

Theyre so close right now. Kacchan shifts Deku’s wrists into one hand & pins them over his head. There’s no platonic way to interpret the position theyre in, & everybody knows it. When kacchan leans down to kiss him, nothing either of them could say could ever explain this away.

Everyone in the chat’s having a fucking field day. Theyve seen everything they need to see, but it just keeps escalating from there. Kacchan deepens the kiss, & deku mewls prettily beneath him, wraps his legs around his waist. A few people start wondering if they should stop this

They ask if anyone has either of their numbers & could call them, let them know theyre still live, but to no avail. The vast majority of people are happy to keep watching anyway.
Within a few minutes, clothes start coming off. Kacchan sheds his shirt, pushes Deku’s up his chest.

“Kacchan, mmh,” he moans, legs pulling kacchan’s hips against his own. Kacchan laughs lowly.
“Yeah? What is it?” He says, smirking. “What do you want, deku?”
“Want /you/, kacchan.”
“But you’ve already got me.” He teases.
“Kacchan...” he whines.

He leans in, lets his lips brush against Deku’s &asks, “you want me to kiss you?” Deku shakes his head, & he hums, runs his fingers up his chest. “Want me to touch you?”
Again, he shakes his head. Kacchan grabs his knees, presses them against his chest.
“You want me to fuck you?”

Deku whines, nods his head vigorously, palms plastered over his hot, red cheeks.
meanwhile, in the chat,
SexyNecromorph69: BAKUGOU FUCKS CONFIRMED
All_ur_base: pls tell me someone’s recording this
HotDad420: on it
Doc: every day I thank god for how fucking stupid these boys are

So kacchan starts pulling Deku’s pants off, reaches for his belt next, and immediately everyone starts makin bets about how big their cocks are.
misterbubbles: bakugou either has an extremely tiny cock or an incomprehensibly large one there’s no in between
(guess which one lmao)

Anyway, once kacchan’s got his cock out, some dudes actually leave the chat because they find it Upsetting. Back to the fucking tho,
Deku’s got his hands around kacchan’s cock the moment his pants are down, sitting up, stroking him with both hands, practically salivating, yknow

He leans down to take him in his mouth, moaning all pretty while he’s sucking him off. Kacchan groans above him, knots his fingers in his hair and says, “thought you wanted me to fuck you.” Deku pops off, stares up at him from under his eyelashes as he runs his tongue up the side

Then he sits back, pushes his underwear off, and says, “so do it, then.” Kacchan eyes him up and down, quirking an eyebrow at way he seemed to be keeping his legs together. He didn’t understand why until he was popping the cap off a bottle of lube, and deku cleared his throat.

“That... that won’t be necessary, kacchan.”
Kacchan stares at him, blankfaced. Pointedly, he glances down at his dick and back to deku. “Do you think this is a fucking game, deku?”

(ADDITIONAL_PYLONS: YEAH DEKU DO U THINK U GOT AN ASS MADE OF STEEL)

Deku opens his legs.

Kacchan looks down, sees the base of a plug resting outside his hole, and he gets that terrifying smirk on his face, the one he does when he knows he’s “got” someone,and drops the lube on the couch cushion. In an instant he gets down into Deku’s space, grabs the base of the plug.

“You fucking nasty little /slut/,” he says, punctuating with a twisting thrust.“Just how long have you had this thing in for?”
Izuku flushes, licks his lips. “Since I got here, a few hours ago...”
“This whole time, huh?” He laughs darkly. “Were you feelin’ it? During the stream?”

He pulls it out partway just to shove it back in, watch the way deku arches his back and whines for him. “Were you gettin all hot and bothered, deku? Was it hard?answerin questions, tryin not to squirm at the feeling of havin your tight little ass filled up so good?”

Deku releases a loud, needy moan, “yesyesyes, it was so good, felt so good inside me, kacchan, please, /please/ fuck me, I can’t take it anymore, plea—“ Kacchan cuts his blabbering off with a kiss that Deku whines into when kacchan slowly slides the plug out and discards it.

He positions the head of his cock against his hole, murmurs, “Yeah, I got you, baby boy,” and slowly sinks inside. Deku immediately reaches around his abdomen, nails scrabbling against his back as he opens his mouth soundlessly, tears springing to his eyes.

(HotDad420: oh wow I just realized my sex life is actually extremely sad lol
everyone: f)
Once kacchan’s all the way in, deku wraps his legs around him too, pulls him down and buries his head in his shoulder. “Fuck me, fuck me, kacchan, please, I can take it—“

Kacchan suddenly pulls out only to thrust back in roughly. Deku fuckin screams. “You can take it, huh? That a challenge, deku?”
He smiles. “Always, kacchan.”
Kacchan returns his grin, grabs him by the hips, says, “if you say so,” & immediately starts fuckin pounding him

Deku screams, cries so pretty when he’s getting fucked. Grabs the pillows and couch cushions and lets the tears stream down his cheeks without even realizing it. That’s about where he is now, underneath kacchan as he viciously fucks his ass, because that’s how he likes it.

Kacchan snarls and bares his teeth and bites into his neck and shoulders like some sort of feral beast, makes his hips slap so hard against Deku’s ass he has to wonder if the neighbors can hear it. (Perhaps not, but his subscribers sure as fuck can.)

“So fucking good,” Kacchan nearly growls into his neck, makes deku shudder. “Takin’ it so fucking good for me, deku, such a good boy..” Deku keens, fingers knotting in kacchan’s hair as the tears keep on coming, streaming down his cheeks as kacchan fucks him hard and deep.

Deku’s getting close when kacchan suddenly scoops him up, keeps his cock inside as he sits on the couch with deku straddling him, and deku follows along, puts his hands on kacchan’s shoulders and starts riding him desperately.
“Fuck yeah, that’s it—“ he groans.

(Incidentally, the viewers now have the perfect view of his ass bouncing on kacchan’s cock)
“Kacchan, god, I’m so— so c-close,”
“Yeah?” He reaches down, grabs Deku’s cock and starts stroking. “You gonna cum for me, deku? Gonna cum on my cock like a good boy?”

Deku nods, tears slipping down his cheeks still, falling onto kacchan’s chest & shoulders from time to time, & that shit just turns him on even more.
Kacchan grabs Deku’s ass, spreads him open & starts fucking up into him.
“Fucking do it, then,”he groans. “Cum for me, I-zu-ku-"

With a choked up cry, deku does. Hips twitching as he’s being fucked into hand desperately milking his cock as cums all over kacchan’s chest & stomach.
“Fuck, fuck yes, there’s a good boy, g-god,” Kacchan squeezes his ass harder, starts slamming deku down to meet his thrusts.

Within minutes, hes cumming too, groaning “Deku” into his shoulder & biting down on his neck as he cums inside him, fills him up good, makes Deku’s spent cock jerk at the sensation.
They come down slowly, panting, & kacchan rests his chin on Deku’s shoulder, staring at nothing.

...until he isn’t, that is.
He doesn’t quite comprehend it at first, his mind still hazy, but the significance of it creeps steadily creeps into his mind until it’s all there is left.
“Deku...”
“Hm?"
“Why... the fuck... is the recording light still on...?”

The end lmao
