"You know, I knew the second I saw you that you were just a bitchy bottom in need of a proper fucking." Eijirou growled into Bakugou's ear, two fingers deep in his ass.
The blond moaned lowly, the sound nearly drowned out by the general noise of the machines in the boiler room.
It was true too.
When their dairy coolers had broken down for the umpteenth time and his manager, Aizawa, had finally had enough of the guys who came in and spent hours doing nothing, he had asked for the refrigeration company's best repairman.
And when Bakugou had stormed into their store that first time, with a scowl on his pretty face, words sharp and temper already flaring, Eijirou had known.
He'd seen the way that Bakugou's eyes had raked up and down his body, the way his cheeks had flushed a cute shade of pink, and the way his eyes narrowed and his scowl got deeper, as he pointedly looked away.
Oh, he'd known just what Bakugou needed.
It was at the very least, highly unprofessional to hit on, nevermind fuck, the angry refrigeration guy, and he'd risked his job to do it, but considering his current situation, he couldn't regret it.
He had Bakugou pressed up against a wall in the far corner of the dim room with his ass out, out of sight of anyone just coming in, and just a little quieter since the machines were closer to the door.
Bakugou was fucking back onto his fingers so desperately, moaning louder and whining when Eijirou offered him a third to fuck himself with.
Eijirou had been craving this, hadn't even realized how much he had wanted it until their fridges had broken down and a thrill of want had shot through him.
This would be the fifth time Eijirou had fucked him in this very spot, and neither of them ever left unsatisfied.
Bakugou had basically been permanently assigned to their store since it was rare that he wasn't politely asked to never, ever come back to a store. The blond was very good at his job, but his abrasive personality made him hard to work with.
Eijirou's store was one of the few that tolerated him, and the only one to request him.
Despite his demeanor, he could figure out what was wrong, fix it, and get his brains fucked out in half the time it took any other guy to even set up his toolkit, and Aizawa more than appreciated it.
Also, Eijirou himself seemed to be one of the few who could actually manage to withstand Bakugou's curses and insults, which was helpful since his old dairy coolers broke down way too often.
"You've been missing this, haven't you, baby?" Eijirou asked, taking back control and pushing his fingers in harder, deeper.
The moan the blond let out was beyond worth the risk.
"God, Shitty Hair, just get your fucking cock in me." Bakugou tried to demand, but it mostly just sounded needy.
"Soon, baby." Eijirou promised, running soothing fingers down Bakugou's spine as he pulled his fingers out.
"What are you- fuck..." Bakugou cut off with a moan as Eijirou sunk to his knees and spread his ass to reveal his wet, stretched hole.
The first time they hadn't any lube and Eijirou had eaten his ass out until Bakugou was begging, though these days it wasn't necessary since Bakugou had started bringing a tube in his toolkit when he knew he was coming to Eijirou's store.
But Eijirou was feeling nostalgic.
"Quiet now, we can't have anyone hearing me ruining you." Eijirou said, just loud enough to be heard over the hum of the machinery.
It was warm and a little humid in the room, and there was a sheen of sweat on both their bodies. Eijirou had stripped Bakugou almost completely, his pants and boxers at his ankles and his thin black undershirt pushed up under his armpits.
The view of the blonde's smooth, tan skin slick with sweat was a sight to behold.
Especially from Eijirou's current point of view.
Leaning forward, the redhead lapped at Bakugou's hole, ignoring the slight lube taste that lingered, and reveled in the man's soft moans, the way his thighs were trembling.
When he pushed his tongue in, Bakugou gasped and tensed up, before pressing his hips back for more.
"That's it, baby. Present it for me." Eijirou pulled back just enough to encourage him, grinning at the answering whine Bakugou made as he did as he was told, arching his back to push his ass out further.
Eijirou groaned and dove back in, licking and fucking the loose hole with his tongue as his hands roughly squeezed his toned thighs and ass.
"Please, God, please, Kirishima, fuck me. I'm ready, I'm wet, just- fuck!" Bakugou cried out so sweetly when Eijirou plunged his three fingers back in and licked around them. "P-please!"
Pulling his fingers out, and standing up, Eijirou undid his pants and took his uniform shirt off so it wouldn't get stained.
The release of pressure on his throbbing cock was a welcome release, and Eijirou sighed out as he used the slick already on his fingers to lube his cock at least a little.
He'd learned that Bakugou actually liked it a little on the dry side, the burn of the friction always drove him crazy.
"Here you go, baby." Eijirou moaned as he pushed into Bakugou's hole.
It was warm and wet, still so tight around his cock despite his earlier preparation.
"Ah, fuck! It's so big, jesus christ." Bakugou moaned, eagerly fucking himself back on Eijirou's cock the same way he had his fingers.
"You like it?" Eijirou hissed out, as he gripped Bakugou's surprisingly full hips, keeping him in place so he could fuck him harder.
"Fuck, shit, yes!" Bakugou groaned out desperately.
He was making little moans that seemed to be punched out of his chest with every hard thrust Eijirou gave him.
"You gonna come on my cock, like the bitch you are?" Eijirou asked lowly, dangerously into Bakugou's ear.
"F-fuck!" Bakugou's nails were desperately digging into the drywall, leaving marks as he tried to curl in on himself, too overwhelmed.
Well, he couldn't have the blond damaging the wall. Someone would notice that for sure.
Pausing his thrusts, Eijirou took two steps back from the wall, pulling Bakugou with him, away from it.
"Hey, what-" Eijirou shifted his grip to the blonde's arms, gripping his biceps just above his elbows and pulling his arms back so his chest was pushed out.
"Ah! Kirishima!" Bakugou's moan was breathy, the new angle pushing deeper.
Eijirou grinned wickedly and used his new leverage to fuck harder and deeper into the blond, his ass looked amazing, jiggling every time Eijirou's hips thrust against him.
"Shit! Shit! I'm gonna-!" Bakugou didn't get to finish his sentence, a long moan cutting him off as he came untouched.
"God, baby, yes." Eijirou moaned out, fucking in faster when the blonde's ass tightened around him.
Bakugou was babbling overstimulated nonsense as Eijirou continued to fuck him through his oversensitivity.
"Shit. I'm gonna come inside. A nice load will satisfy you enough for you to play nice today, right?" Eijirou growled, feeling his orgasm coming.
"Yes! Yes, shit, I'll be nice!" Bakugou promised, voice high and sweet.
Eijirou bared his teeth as he came inside the blond.
"I know you will be."
