In Your Shadow [Chapter 33.5 - NSFW]

I am once again leaving a reminder here that everyone in this fic is an adult who can do what they want, just in case.

[Chapter 33]

Katsuki rolled over to his other side, grumbling to himself quietly. He just couldn’t seem to get his brain to switch off, even though he was tired as hell, and he just wanted a little bit of shut-eye before he had to go suck up to Deku again and hope he was forgiven for the stupid tie bullshit. He’d been out all night on patrols, and by all rights he should’ve been exhausted, but instead there he was, lying in his stupid bed with the stupid sun rising beyond his windows, his stupid brain refusing to quiet down for him, to let him get even a hint of rest while the building was coming alive below him.

In a moment of inspiration, Katsuki fished around in the bedside table, finding a tube of moisturiser he’d brought along for his dry hands – having so many patrols and sparring matches was starting to take a toll on his skin. More importantly, though, he was alone. He was in a private room, with a lock on the door, first-class soundproofing as long as the windows were closed, and no stupid classmates listening in from the other side of a thin wall.

He doused his hand in moisturiser and kicked off his boxers, taking one last glance at the locked door before he caved.

Patience, Katsuki. There’s no rush.

The voice in his head sounded eerily familiar, but Katsuki refused to look into it any deeper, lest he make some sort of self-discovery he wasn’t willing to face any time soon.

You know the rules, Katsuki. Do what I tell you.

Fuck, that voice really wasn’t going to leave him alone, huh?

Say it.

“Yes, Deku,” he whispered to himself, face burning.

Good work, you’re learning nicely.

He could practically see that smug look on the asshole’s face, but somehow that didn’t stop him – if anything his hand began to stroke a little quicker, his brain finally conceding that yeah, okay, he really was about to jerk off to this.

Behave yourself, Katsuki, don’t go getting ahead of yourself.

With a little whine, Katsuki slowed down again, squeezing his eyes shut tightly.

Take it slow. Tease yourself a little, have some fun.

He ran his thumb over the tip, bucking up into his own grip and gasping. It really had been a while, apparently he was so damn pent up that he was getting off to his boss ordering him around. Stupid.

He shifted his free hand to his chest, biting back a moan when he pinched at his nipple, imagining a pair of thick, scarred fingers doing it in his place. Because that was exactly the sort of thing Deku would do – with that damn smirk of his, so ready to tease and torment Katsuki for his own amusement.

Come on then, show me.

He pinched a little harder, fisting his dick with the other hand, and began stroking himself again, taking it slow.

Stop slouching like that or I’ll have to put a corset on you or something

Fuck, that one wasn’t even relevant, it just lived in his mind rent-free. Somewhere in the haze of his occupied brain, he knew that one probably wasn’t even related to the jerking off – he’d been hearing it a few times a day, every day, since Deku had said it.

Finger yourself.

Well. That one was new. He was fairly certain he’d never heard Deku say anything of the sort – he’d have been pretty concerned if he had heard it, considering they had a professional relationship.

Now, Katsuki.

“Fuck.”

Katsuki pulled one leg back to his chest, reaching for the moisturiser again, and this time he dropped his slicked-up hand to his ass, rubbing his fingers across his hole.

Look at you, Mister Flexibility.

Something about Deku teasing him was just too fucking hot and Katsuki wasn’t even afraid to admit it – at least not in that exact moment. He could just imagine Deku folding him in half as he fucked him hard and fast, or bending him over a barre, pounding into him as he used every ounce of his strength to keep from swinging over the other side.

Fuck, he was never gonna be able to use the portable barre again, after that image – he’d have to get there early and make sure he got a spot at the wall. He wondered if Mina would understand if he changed up their setup too – honestly, she’d probably have loved to hear the reason why, that weird fucker.

Come on, Katsuki. Be good for me.

Would Deku praise him like that in bed? Tell him how good he felt, how well he was taking Deku’s dick, what a good boy he was being? He moaned, pressing his fingertip a little deeper until he could feel it inside himself, gently sliding in and out through the tight rim. Deku’s fingers would have felt better, he knew – all thick and hard with muscle, and probably relentless, fucking him long after he’d cum, just to watch him squirm and writhe and complain.

A heavy knock on the door broke Katsuki out of his daydream, and he sat bolt upright in his sweaty sheets, ass aching where he’d torn his finger out far too quickly.

“Katsuki!” that same voice called, this time without the sultry undertones. “Be in the sparring rooms in five minutes if you want a round!”

Fuck. Shit. Crap. How was he supposed to face Deku after that? How was he supposed to spar with him, seeing all those muscles flex and imagining how many ways they could wrap around him, pin him down, bend him over every surface in the damn building?

Not to mention, Katsuki hadn’t even gotten to finish. The day just got worse and worse.

“Coming!” he yelled back all the same, stumbling to his feet and hunting down his costume, still a little sweaty from the overnight patrols. Not that it mattered, when he was going to be drenched in just a few minutes – from sweat of course.

Cursing himself, and Deku, and the agency building, and everything else about the situation, he dragged himself back off the bed, tossing the moisturiser back in the drawer so he wouldn’t have to look at it again. Despite his complaints, though, he still got dressed in his costume – picking the new one for the sake of getting some more practice in it – and hurried downstairs to the sparring rooms. To his surprise, Mirio was there too, shooting him a bright smile the moment he stepped into the room.

“Are you gonna spar with me too?” Katsuki asked eagerly.

“Not today,” Mirio laughed. “I thought maybe I’d do some coaching, attempt to level the playing field a little.”

“Not quite as good, but I’ll take it.”

“Do you need time to warm up?” Deku asked, stretching his arms lightly.

“I’m good,” Katsuki assured him. “I just got back from a patrol.”

“The morning shift?”

“Yeah.”

“Alright, let’s jump in then.”

Right before Katsuki’s eyes, waves of green energy began to lift off Deku’s body, the room filling with the faintest buzz as his quirk kicked into gear. Katsuki blinked at him, stunned for a moment, and Deku just raised an eyebrow at him, smirking.

“What’s wrong, Kacchan?” he teased. “I thought you liked playing with my quirk.”

“Nothing’s wrong,” Katsuki answered immediately, a grin tugging at his lips no matter how hard he tried to contain himself. “This just became the best day of my life.”
