Kirishima shouldn’t be watching.
He shouldn’t be watching.
But he just couldn’t look away.
Why couldn’t he look away?
He just wanted to bring Katsuki some breakfast.
It was innocent, honestly. He was just trying to be nice. It was their one year anniversary of living together as roomies and although Katsuki hated shit like this, Eijiro‘s heart swooped at the way he would mutter a grumpy “/thank you./“
He was just trying to be nice. But there he stood in the hallway, tray of pancakes and orange juice /shaking/ in his grasp as he watched through the crack of his roommate's door.
Why didn’t Katsuki shut the door?
Who leaves a door open while they... they...
An obscene moan left Bakugou’s lips and Kirishima almost dropped his breakfast.
It clattered slightly, the glass sliding around the smooth surface and clinking against the porcelain plate and Eijiro gasped as he caught it.
It wasn’t loud, but Kirishima’s breath hitched and he glanced back through the gap in Katsuki’s door.
But apparently, his flatmate wasn’t alerted, because Katsuki’s hips still ground down, his abdomen clenching and unclenching with every smooth roll.
He was upright in the middle of his bed, just visible through the gap Eijiro was peering through. Between his thighs he straddled a plush, white pillow, folded just so that it wrapped between his legs, the edge rubbing between his cheeks and along his taint.
It folded up over his pretty, pink cock where the wet tip slid in and out of view. Bakugou’s head was thrown back in pleasure, but every so often he’d glance down to look at himself and, /fuck/, Eijiro didn’t blame him.
Those abs moved like waves, rippling in pleasure. His pebbled nipples that Kirishima would do /all the things/ just to have the honour of sucking on for 10 seconds were being thumbed at absently, almost as a second thought.
It made Eijiro’s knuckles turn white around the tray still in his hands.
He’d give those tits all the attention in the world, the attention they /deserved/.
Bakugou’s hips stuttered and he let out a long, loud moan, biting at his lip as he rolled his hips around in circular motions now.
He was indulging, taking his time. Eijiro was so jealous.
He imaged himself under Katsuki in those moments, imagined it was his cock the blond was grinding on and not a pillow. He knew Bakugou would feel so good around him, he could see Katsuki’s muscles knot and clench, and he could almost feel them now around his dick.
Katsuki would have his back to him, riding him slowly, and Eijiro would pull away the flesh of his plump backside so he could watch his cock sliding in and out of the blond’s wet hole. Bakugou was greedy, self indulgent, but Kirishima was more than happy to be there for the ride.
But right now, all Eijiro could do was watch helplessly as Katsuki’s hands ran free all over his soft, creamy skin, and Eijiro tracked them like a hawk. He watched those fingers dip into the muscles and grooves along his stomach, his pecs, grabbing and groping his own body.
Kirishima didn’t realise he was drooling until he felt a blob fall onto his tee, but he didn’t care enough to do anything about it.
He was far too preoccupied watching Katsuki hump into his pillow, the pace slowly picking up.
Katsuki’s hands continued to travel, one pulling at his nipple while one slid down his stomach, around his hip to grab at the flesh of his backside.
It was a rough grab, rough enough to make Katsuki gasp and moan, biting his lips in a smile.
Katsuki dropped forward, landing with his arm out, single palm against his mattress as his hips moved faster, his backside bouncing into the air. With each rut the flesh shook, and slowly Katsuki’s other hand came up so he could suck on his middle finger.
Kirishima’s breath caught. He hadn’t blinked for several minutes now, he dare not to, for if he did he might miss Bakugou reaching back to press that slicked up finger into the valley of his arse. Bakugou threw his head back again, hips rutting harder, the bed beginning to squeak. The mattress bounced with each thrust of his cock into the pillow as he began to fuck himself back onto his finger. Katsuki was hunched over it now, eyes shut, mouth open in bliss.
Kirishima was well aware of how hard he was in his pants, but he couldn’t really do anything about it. Staring was one thing, but jacking off outside his best friends door might be a step too far.
Besides, he was quite content in watching Bakugou’s backside jiggle, faster still as he leaned forward ever more. Kirishima could see his fingers working away, the flex of it across his hand, along his strong forearm and up his thick bicep.
He could see the twitch of the muscle as his roommate fingered himself. He could see how Katsuki’s face contorted in pleasure.
The blond moaned, pouting his lips as he humped harder, faster, pushing his cock into the pillow, thrusting it into the crease he’d created for himself.
His face was flushed, his nipples were swollen, and his hair was sticking to his forehead in places, sweat beaded across his brow.
And then his mouth was dropping all the way open in a loud gasp. He made the most beautiful noise, a broken cry of pleasure and suddenly his hips were stuttering.
Kirishima’s jaw dropped, and he watched Katsuki flop forward entirely, just bracing himself onto his elbow.
He blond slowly ground his hips now, riding out his evident orgasm. He hummed happily, contently, breathing heavily.
Bakugou’s face was dropped, gaze fixated on where his hips were grinding into the pillow, where he was humping into his own cum.
And then he looked up and Eijiro’s heart fell out his fucking arse.
“Enjoy the show?” Katsuki asked with a wink.
And Eijiro promptly dropped the tray.
