Rock Paper Scissors | DkBk Fic

This is something different from normal, but as I mentioned I really wanted to write something based off of that one DkBk pic I recently drew. And it ended up being way longer than I intended it to be. So this is part 1 for now. I want to write a part 2 of the morning after, so look forward to that.

I hope you guys like this, I know I really loved getting to write again. I started off writing TdBk fic, so this was nice.

I'm still thinking on what I want to call this, but I was thinking Rock Paper Scissors. You'll find out why. So that's currently what it's called. (Also if you see any typos or mistakes, I was too excited to proof read properly so I will apologize beforehand)

____________________________________________________________________________________

Somehow Katsuki is dreaming. It's either that or he's died and somehow made his way into a different realm where his current situation could ever make sense however unfeasibly so.

The situation where Deku's glued himself to his side, legs tangled over and under him into a koala hold. In which Katsuki is playing the part of said confused and very naked tree, who doesn't know whether to make himself scarce or comfortable. If trees, of course, could do either. Maybe they can in whatever realm Katsuki has been teleported into through some insane quirk related incident. Because Katsuki himself has no idea which course of action to take.

Deku makes a noise next to him, as if sensing his indecision, stirring slightly. It’s a small grumble, something akin to a mewl, not unlike a cat who's nestled himself into the perfect sleeping position without a care in the world before he burrows his face back into Katsuki's chest. Cheek squished flat against him.

It's cute.

Fuck.

Every soft exhale has hot breath ghosting over Katsuki's skin, doing absolutely nothing to calm his rising panic, or dissuade his dick from stirring in interest. Even though Katsuki is pretty sure he's more than spent for the next few hours at least.

It shouldn't be cute

And it definitely shouldn't have his dick, the traitorous appendage, waking up for another go.

There’s a muffled Kacchan.

A soft warning before Deku’s hand is wrapping more around his midsection, squeezing in impossibly closer as if making the decision to stay for him.

And maybe Katsuki is a weak man. Maybe it’s the residual alcohol in his system. Or maybe it’s his apparent lack of self control.

Whatever it is, Katsuki finds himself giving in without even really trying to fight it much at all.

-

“Kacchan! You made it.”

“Those idiots promised to buy me lunch for a week if I came. And I plan to get their money’s worth.”

The party had been Uraraka’s doing.Going had been Kirishima’s doing. Making him dress to impress had been Mina’s doing.

So honestly, it’s easy to point fingers. Katsuki knows exactly who to blame for his current situation when it inevitably blows up in his face.

“Oh.I see.” Deku had smiled shyly, twirling his fingers nervously before he looked Katsuki in the eye and followed it up with: “I kind of came to see you.”

Only to then promptly disappear into the crowd of former UA students when Sero showed up out of nowhere to drag his attention away from what was only the first of many truly confounding and befuddling remarks.

He’d been nursing his third beer of the evening, enjoying some peace and quiet out on the balcony when Deku sidled up next to him. Some kind of French apple cider in hand, which Katsuki suspects he’d been given by Aoyama.

“You look great.”  Said so quickly Katsuki’s not quite sure he heard it at all.

“Mina chose the shirt.” Because she had. Katsuki had objected because there was no way he was wearing sheer fabric in the middle of winter, no matter how barely see-through it was, because Mina’s standards of acceptable sheerness were not the same as Katsuki’s. Ultimately of course Mina had threatened to melt the shirt he’d chosen himself so...

“I like it.”

“Oh. I don’t even know where this dumb thing came from. I could ask-”

Deku had giggled at his response, effectively stopping him mid-sentence. “No, I like it on you.”

“You- Oh- Thanks.” Katsuki had tried to hide his blush by awkwardly sipping his beer and avoiding Deku’s eye.

“It’s from your photoshoot back in July.” How the fuck? “They used those pictures for that poll.”

Deku had taken his silence as an opening to get in closer. Casually turning to lean on the balustrade Katsuki was looking out over, fingers almost touching the hand holding Katsuki’s bear as he slid them over the wood.

“Top 10 most fuckable heroes.” The edge of a smirk had played on Deku’s lips, raised bottle of cider close to hiding it but not quite. “You were number 4.”

“That was not the fucking title of that article.”

“It was implied.” A sip of cider and then he’d angled his head to look at Katsuki again. “I think you should have been number 1.”

Katsuki had promptly developed the ability to choke on thin air. There had been no way he was drunk enough with only two beers down to be imagining the whole thing.

“Deku, what-”

“Ah. My cider’s empty. Got to go get a refill.”

For a second Katsuki had been stunned into silence. Which was just enough time for Deku to make his escape and get pulled back into the crowd of extras inside.

He’d paid more attention to Deku after that. Trying to figure out if maybe he wasn’t drunk, but instead Deku was. But then Deku really wasn’t drinking all that much and he’d always had a ridiculously high alcohol tolerance. Further investigation also proved the cider wasn’t all that strong to begin with.

Which left only one option.

Deku, for whatever reason, was most definitely flirting with him.

The next time it happened, Katsuki was stepping into the hallway in an attempt to escape whatever party game Kaminari had been roping everyone into, when Deku just happened to be standing there.

There was no way it was a coincidence, but Katsuki also had no way of proving it.

“You’re not leaving without me, are you, Kacchan?”

“You should hurry up, Deku. They’re just about to make fools out of themselves in there. Sounds like your kind of thing.”

It was mean and unnecessarily asinine, but Deku laughed it off anyway. As if he could see right through him.

“I think you’re more my kind of thing.”

Blunt. To the point. Making Katsuki’s cheeks burn in the dimly-lit hallway, praying Deku wasn’t able to tell.

What the fuck was in that cider? Did the French somehow perfect the concept of liquid courage? Because Katsuki was not above cursing out the entirety of France and Aoyama for bringing it to the party.

“But,” Deku said with a glance up ahead, “Maybe someone should make sure nobody hurts themselves.”

He gave Katsuki a nod, something that suspiciously seemed like a wink and then started on his way towards the rising noise coming from the other room. Shouts and clinking of glasses.

“Want to find out?” Katsuki asked, staring straight ahead, refusing to make eye contact as the question slipped out.

Deku looked at him in confusion, eyes wide and brows raised. Tables turned on him this time around and Katsuki might have just done it to get a kick out of it. Because this felt like sweet vindication after everything else.

“Whether I should have been number one on your dumb list.”

-

The trek to Deku’s apartment was both exhilarating and the most frustrating thing Katsuki had ever done. Dodging and weaving from alley to alley as Deku would drag him into each one to sneak in a kiss or a chance to feel him up along the way.

In all honesty, it might have been a miracle they even made it to Deku’s apartment in the first place.

And as soon as Deku managed to lead them through his bedroom door, all bets and clothes were off. Eager to touch as much skin as they could both get their hands on.

There was a sort of giddiness in the way Deku cupped his face, thumbs guiding his jaw to get another kiss in. Contagious in the way he could feel the corners of Deku’s lips curled up into a smile that mirrored on Katsuki’s own.

Katsuki thought he might be content doing this for however long Deku would let him. Happy to feel the softness of Deku’s rug underneath his feet and the tenderness of his fingertips sliding down his jaw and pulling him in infinitely closer still.

But then Deku was moving back, forcing Katsuki to follow in a stumble of limbs towards the bed.

Deku went easily, letting himself fall back on it as he pulled Katsuki along. Their teeth clinked together, because Deku even while bouncing on his mattress refused to give him even a second’s rest. Lips glued to his as Katsuki cursed softly.

There was a sorry thrown out there somewhere. Getting lost between the twin moans echoing through the room when Deku rolled his hips up.

Katsuki could feel Deku’s dick on his. Could feel them sliding together and he did not have to be told twice to start moving. To grind down as he found his balance by bracing himself on his elbows, placing them next to Deku’s head so he could swoop down to reconnect their lips.

Shit.

How was kissing Deku this addicting? How did grinding get him this turned on?

He wanted to, no needed to get inside Deku. Needed to fuck him until he figured out why Deku’s body was the most addicting thing he’d ever found. Needed to fuck him until he had proved Deku right. That he should have been number one on that dumb list.

A leg curled its way around his, and then before he completely realized how it happened, Deku had flipped them. Rolling up and over him to press Katsuki into the mattress instead.

His protest at the switch of position died on his tongue with a swift kiss, followed by lips tracing down his neck. Down. Sucking marks into his skin and leaving nips whenever Katsuki twitched in reciprocation. All the way to his stomach, where Deku rested his chin and glanced back up at him, a grin with a twist of wickedness hidden in it.

Shit.

Could Deku feel the way his stomach fluttered at the sight of that grin?

Fuck.

There was a hand on his dick then. Proceeding the feel of Deku’s tongue from the base of it up to the tip. Stopping to dip the head into his mouth, slowly, so teasingly languid in his ministrations that it had Katsuki’s hands digging into the pillow above him. A keen stuck somewhere at the back of his throat when Deku’s tongue swirled around his head.

“Deku.” Katsuki tried rolling his hips, only to be stopped by a hand pressing him back down on his stomach. “Just fucking-”

“Hmmmm.” Deku lifted his eyes to look at him. Mouth opening to drop Katsuki’s dick back on his tongue. Letting it sit for a second. “You going to cum for me if I do?”

Asshole.

“Going to be my perfect Kacchan and cum for me?”

“Heh.” Because Katsuki, regardless of the situation, regardless of who had the upper hand, regardless of his cheeks heating up, had to taunt. “Who says you’ve got the skill, nerd.”

Deku took the remark in stride. Not paying it any heed and diving right back in.

In a matter of seconds, Deku had Katsuki’s entire dick engulfed in his mouth. Warm and wet and absolutely amazing. He was bobbing his head, dragging his tongue flat across the underside of Katsuki’s dick, before swirling it around the head again as he came up. Pressing along the divot on the underside and then sucking as he took the whole thing in again.

Shit.

Katsuki would not last long, despite his taunting.

Deku had always been eager to please. And Katsuki was finding he really enjoyed that eagerness right now.

He could tell when Deku was observing his reaction. Could tell when he adjusted a move to make Katsuki enjoy it that much more. As if he was taking notes to later scribble down in some god damn sex notebook. Katsuki honestly would not be surprised. Nor did he care right now. Deku could take all the notes he wanted if this was the result.

Katsuki barely noticed when the hand holding him down slipped away. Only vaguely aware Deku was pushing his legs further apart to fit better in between. It was fine as long as Deku kept doing whatever it was that he was doing with his tongue.

But then a suspiciously wet finger was pressing against his hole and he nearly kneed Deku in the head.

“The fuck, Deku.”

Deku let go of his dick with a pop as he stared up at him. “I thought you wanted to fuck?”

“I’m not the bottom.”

“Oh.”

Deku didn’t, however, look deterred in the slightest. Finger still very much pressing against him.

“Want to rock-paper-scissors for it?” He asked nonchalantly, tongue coming out to lick Katsuki’s dick again. As if he was just about to resume his blow job.

“Ah- You- What?”

Deku shrugged his shoulders as if his eyes weren’t filled with a determination to devour Katsuki right then and there. “Winner gets to top.”

“That’s ridiculous.”

“Are you scared you’ll lose, Kacchan?”

“Fuck you.”

“I’m trying.”

“Fine.”

Which is how Katsuki ended up being bested by Deku in a fucking game of rock paper scissors. By Deku playing scissors and Katsuki being tempted to use his paper to chop Deku’s head in two.

“Looks like I win.”

“Screw you. Best two out of- FUCK.”

Fully ignoring his objection, Deku had decided then and there he was going back to deepthroating Katsuki’s dick while also breaching past Katsuki’s rim to push his finger in. Curling it up in a motion that had him just missing Katsuki’s prostate.

“You can’t just- Stop- Oh, you’re so going to d- ah- hmmm- shit. Don’t stop, fuck. Just like that.”

He could feel Deku grinning around his fucking dick as he sucked him in, vibrating his throat with a hum. Slipping in a second finger while Katsuki was distracted and then- Then Katsuki was seeing stars as they dragged right across that one bundle of nerves that they had barely missed before.

Katsuki wasn’t sure what gave him away, but Deku knew instantly. Maybe it was a hitch in his breath. A stutter in his hips. The way his hands flew away to grip the pillow again, trying his best to keep his quirk from ruining the fabric.

He pressed the advantage, putting constant pressure on the same spot. Tongue swirling, dipping and sucking. Then starting over again.

Maybe it was embarrassingly quick, but Katsuki could feel his orgasm fast approaching. Could feel the tension in his lower stomach building until it was unbearable. Until anything could make it snap.

“Fuck, I’m-”

Fingertips pressed on his prostate with a vengeance. Somewhere in the back of his head Katsuki noted that there was a third now as the dam holding back his orgasm broke.

Deku took him halfway down, letting his cockhead sit on his tongue as Katsuki shot up into his mouth. He swallowed it all, every last drop that he could wring out of him and then waited for Katsuki to fully soften, engulfed by the warm wet heat of his mouth still. Only then did he let his dick slip, licking it as Katsuki moaned in oversensitivity. Fingers still working his ass open.

Tracking time post-orgasm became difficult, but it must have been a while before Deku finally slipped his fingers out too, wiping them on the sheets as he sat up on his knees.

“Are you good, Kacchan?”

He was unsure whether or not he succeeded in a successful glare, but the way Deku dipped his head down for a peck on the lips meant his message had been clear enough. Or maybe the fact that he was painfully hard again had been all Deku had to know.

In contrast to Deku’s prep, it did not take him long at all to position himself in place and push in.

At first it’s slow and languid. Leisurely in the steady drag of Deku’s dick across his prostate that was as amazing as it was infuriating.

Up until Katsuki let a moan escape.

“Ah- Deku…”

Slow pace momentarily halting in its tracks as the other looked at him. A mixture of awe and determination swirling in green as they met half-lidded red.

“Move.”

Because if Deku was going to top, then the least he could do was fuck Katsuki like meant it.

Hands moved to his legs, propping them up, guiding Katsuki’s knees to curl around Deku’s sides. Fingers splayed open to caress before gripping hard, leaving Katsuki no room to break the hold should he try. Even if Katsuki was sure Deku would just as easily let him go if he were to say no. And that should not be a turn on, but it was.

Slowly Deku’s cadence picked up again. Pushing in and out. Dragging across that one spot like he wanted to brag about how easily he found it time and time again. Like he was trying to prove a point and drive it home.

Then picking up speed, until there was no time for Katsuki to think about anything but Deku.

Deku.

Deku who was starting to ramble. Muttering praise left and right as he went. Unable to stop himself, as if the words would build up inside him otherwise and cause him to combust.

“The best.”

Never once stopping to catch his breath. Pace brutally delicious.

“Always the best, Kacchan.”

Like a tidal wave accompanying the sea of gasps and pants leaving Katsuki’s own lips.

“So good, Kacchan.”

Another thrust, nailing his prostate with deadly precision, eliciting a choked off moan as he could feel himself squeezing around Deku in reply.

“Feels amazing.”

Katsuki had never found Deku’s rambling hot. Maybe cute. But he would be damned if the praise weaving its way into his ears wasn’t mercilessly stirring those butterflies persistent in taking up residence in his stomach.

“You’re so beautiful.” Deku’s mouth latches onto his neck again. Sucking and nipping while his rhythm went uninterrupted. “Wanted you so bad.”

“Ah -fuck- Deku.” His neck was going to look like it was mauled by a wild animal at this point. “Shut -ah- up -fuck.”

Because he was sure that if Deku kept talking, then Katsuki would not be able to hold off his orgasm for much longer.

“It’s true.”

Deku’s fingers slipped for a second where they were holding on to his legs. Grip loosening ever so slightly. A sign that he was close as well.

“Kacchan.” It was close to a whine. A plea for something. Katsuki had no idea what for.

But then he was cumming. Suddenly and violently with Deku twitching in his ass as he felt his orgasm take hold. And fuck. Deku was cumming too.

Hot ropes of cum filled him up as Deku’s rhythm stuttered to a halt and the grip on his legs failed, hands falling down to Katsuki’s sides as he hunched over him. Mouth drawn in a silent oh.

Katsuki could see Deku’s muscles contracting in time with the spasms of spent he could still feel entering him. And then Deku was looking him in the eyes. A triumphant glint in his as he pressed his hips closer, sliding in his dick just that little bit further and making Katsuki gasp.

A small roll had his softening dick press up against Katsuki’s prostate one last time and then he was pulling out ever so slowly, gently as if not to hurt him.

As if Katsuki wasn’t sure to feel everything in the morning for days to come.

“We should have probably used a condom,” Deku said. Voice a little hoarse as he watched his cum drip out of Katsuki, cheeks an adorable shade of red. “That’s err… I err…”

Katsuki would reply or laugh at him, but he was finding he was short on breath and brain power to form anything other than a quiet moan or pant at this point, let alone a coherent sentence.

Suddenly there was a towel.

Procured out of thin air or the depths of Deku’s night stand. Katsuki would most likely never know. But it was there. Soft as Deku carefully wiped him clean. Every now and then ghosting fingertips along Katsuki’s still sensitive skin. It had his muscles involuntarily twitching in response, earning him a soft laugh.

He swiped at Deku’s hand, missing completely, but Deku raised his hand in surrender nonetheless. Chucking the towel out of sight and plopping back down next to Katsuki.

An arm sneaked around his waist, a pair of legs tangled with his and Deku’s cheek dropped on his chest. Easily slotting into place with a whisper on his bare skin.

“So perfect, Kacchan.”

And Katsuki was officially fucked.
