Thank fuck they went to sleep.
He didn’t want to come in the first place, too many people for too long, but Kirishima's puppy eyes were so fucking annoying he had to say yes. And he’s been walking around naked all day, shamelessly showing off his assets for anyone to see, hunger consuming him from inside every time a muscle tensed, every time a sigh left his plush, wet lips in the onsen, every time he pushed his shitty hair back and smirked at him asking if he was having fun.
Torture.
And now that the extras were sleeping, he’d have his payback.
Bakugou shifted in his futon, staring at the person lying right beside him while calloused fingers kept himself open and ready. The dim source of light came from the heater, glowing against Kirishima’s beautiful features, hair sprayed over the pillow, facing up while sheets slipped down.
And he had enough, too hard, horny and annoyed to even think about the consequences.
Swiftly and silently, the blond pushed aside his covers, lifting Kirishima’s just to get underneath his. He stopped for a second to admire the man below him, cock throbbing between Bakugou’s legs, slowly opening the redhead’s yukata to reveal warm, golden skin.
The fucker laid there snoring lightly, a feast to the eyes, no underwear as expected, and his soft, thick cock resting between black curls. Using the slick from his lubed ass, Bakugou fisted the sleeping beauty slowly, carefully, unhurried.
Kirishima shifted a bit in his sleep, a soft whine leaving those pretty lips, brows slightly frowning. His length filled up in no time, lube shining under the dim light making its glands and girth so appealing Bakugou clenched around nothing, guts churning in anticipation.
Exhaling softly, he lifted himself on his knees, taking Kirishima’s cock to his hole, rubbing and pushing down, sinking little by little, filling him just right. Bakugou closed his eyes for a second, licking his lips, and he opened them to a startled gasp.
He was awake, “What the, Bak—” He slammed a hand over his own lips, sleepy eyes closing when balls touched the blond’s ass.
Bakugou leaned over his boyfriend, whispering in his ear, “Don’t wake up your shitty friends or I’ll have to stop, and you don’t want that, do you?”
Kirishima bent over himself, grabbing the sheets while activating his quirk, a soft rip of clothing too loud in the otherwise quiet room. Bakugou smirked, staring at the mess he already was, pulling from the blankets to cover them properly, sitting on Kirishima’s cock and trying to keep it together even when his cock dripped from the stimulation.
It was pulsing inside him, wrapped inside the tight heat of his ass and pleasure zipped through him as soon as he lifted from it, the drag impossibly delightful after playing with himself for so long.
Kirishima snapped his eyes open, full of lust and hunger, devouring every inch of Bakugou’s skin. Huge hands held tight on his tiny waist, hips rolling up to meet Bakugou’s slow, oh so slow pace, “Fuck, so good”
Bakugou lost himself in the continuous but unhurried stimulation to his prostate, lips parting in a hushed curse, eyebrows coming together and eyes closing. It felt good, so good, real good, pants becoming little noises Kirishima fucked out of him.
Mina shifted in his futon, and both froze for a second, resuming the slow movements while quietly listening to their friends, smirking at each other, Kirishima shushing him while his thumb caressed his hip bone.
They weren’t used to fuck this slow, this silent, but it was nerve-wracking and absolute bliss, the proximity of their climax tensing their abs, twitching their cocks, turning them into panting messes.
Bakugou speeded up the roll of hips, taking out half the length to harshly meet Kirishima’s thrusts halfway down. And he had to bite back a moan, shifting it into a low growl when deft fingers twisted and pulled from his nipples.
He clenched hard, close, too close, and between half-lidded eyes above burning cheeks, he read “I’m gonna come” from Kirishima’s silent lips. Bakugou dug his nails on Kirishima’s chest, nodding, huffing from his nose, and falling forwards when the red-haired took charge of the situation.
He grabbed both Bakugou’s asscheeks, breathing hard on his neck, biting down the tender meat there, pushing into him in uncoordinated thrusts. Bakugou latched their mouths together to suffocate his moans, cock throbbing against Kirishima’s abs, painting them white.
And he felt the spasms inside his ass seconds after, the redhead fucking him slowly, blowing his load bit by a bit, deep moans rumbling in his chest and traveling to Bakugou’s lips. His chest hurt from the effort of keeping his breathing quiet, kisses now turning soft between suffocated puffs of air and red cheeks.
Kirishima, ever the sappy one, nuzzled his cheek, kissing it softly, arms curling around his waist in a tight hug, “that was the hottest thing ever” the smile was evident in the fucker’s voice.
“Fucking, dirty pervert” Bakugou bit his lower lip and pulled, making Kirishima giggle.
“Look who’s talking” Kirishima’s slipped from his hole, fingers hastily reaching down to play with the cum dripping from it, “what a mess, you need to clean up.”
“And who’s fault is that?”
“Yours?”
“For fucks sake go clean yourselves and if you want a second round do it in the onsen, I wanna sleep” Mina snapped, grunting afterward. Denki hid under the covers and Sero laughed against his pillow. Kirishima hissed, violently blushing, rubbing his face.
“Sorry guys, so much for being sneaky, huh?” Bakugou stared at that mischievous grin of pointy teeth and clicked his tongue.
“Shut the fuck up and come with me”
They got up, covering themselves with stained yukatas and Kirishima held his hand, smiling brightly and winking “Whenever you want me to”
