“This has to be a joke,” Bakugo says, looking at the hotel bedroom that was assigned for their mission, it was supposed to have two beds, but there’s one single bed that probably won’t fit the two proheroes.
“Kacchan, I’ll sleep on the floor if you want–,” Izuku says, seeing the frown on Bakugo’s face, but he’s quick to answer, “–no, then your back hurts, and you fuck up our mission,” he sighs, “we’ll make it work,” looking away as he felt himself blush. “If Kacchan says so,” Izuku heads to the bathroom to change out of his costume and shower, Katsuki stays on his place, looking at the bed, “he’s going to be close as hell,” he thinks.
Nighttime arrives, the two of them are sitting on opposite sides of the bed, “why isn’t he laying down!?” Bakugo panics, “what are you waiting for nerd?” He asks, in hopes the OFA user will lay down first and make things less awkward. “Alright, alright,” Izuku lays down with his arms open, “you’re taking up all the space! Move you idiot!” Katsuki yells, but Izuku just chuckles, “you always move a lot during the night, if I hold you, you won’t fall off the bed,” “always so considerate…” he stays quiet, and lays down, back facing him with his head on Izuku’s bicep, Deku is quick to wrap his other arm around him, pulling him closer.
“Kacchan, you’re so warm…” Izuku whispers, face buried in Katsuki’s neck. “You should know that by now, explosions and all…” If he wasn’t blushing before, he now was, he could feel Izuku press up against him.
He did his best to ignore it, but Bakugo woke up in the middle of the night to Izuku breathing heavily against his ear, slowly thrusting his hips to meet Katsuki’s, who was starting to feel hazy, he wasn’t used to this, and Izuku didn’t look like he was going to wake up any time soon. “Kacchan…” Izuku mumbles in his sleep, Bakugo could feel Izuku’s length sliding against his ass, he whines, pushing his ass back to meet Izuku’s hips, both his hands were free, he cups his own bulge, brushing against his palm to relieve some pleasure, the other went under his tank top, brushing his nipples.
“Zuku…” He gasps, he hears the other softly groan, “please…” he begs, wanting the other to wake up, “is he dreaming about me!?” that seems like the only reasonable explanation to Bakugo, who keeps whimpering as he tugs and twists the sensitive nub under his shirt.
A few minutes pass, and Izuku bucks his hips against his ass, reaching his end, Bakugo can feel his heart beat against his back, following close, he comes in the confines of his pants, he moans as he lays against Izuku’s back, lowly whimpering.
“Did you enjoy that Kacchan?”
“Huh?”
“HUH!?”
