"Alright Deku, listen up!" Katsuki stepped closer to Izuku, making him back up instinctively. He could hear his own heartbeat in his ears over his uneven breath as he continued to be sized up like prey by Katsuki, who licked his lips.

Bakugou started again,"I'm going to make you feel so sore in the morning, you'll limp. I hope you walk home to show everyone what a shameful little slut you are. Maybe one of your little friends'll see? Would you want them knowing how disgusting you are?" Dirty talk was always Bakugou's favorite, but this time, it looked like Midoriya was almost crying. Snorting in annoyance, Katsuki took another step forward, Izuku's body sandwiched against him and his bed. "Y'know I'm not going to actually hurt you right, fucker?"

He placed a soft kiss on his trembling boyfriend's forehead, his voice soft. "Relax, dumbass, this is supposed to feel good for both of us, and it won't if you don't relax."

"Ah, yeah K-Kacchan...," Izuku mumbled, remembering the last time that they had arranged a sleepover. It was a lot more going over safe words and comfort zones, but nice nonetheless.

"What did I say?" Katsuki growled into Izuku's ear, slipping a knee between his legs while grazing his earlobe. He could feel Izuku's growing arousal already. It was disgusting how much Midoriya enjoyed this, but it was the same with Bakugou.

"I-I'm not supposed to call you that, Bakugou-sama." Izuku's whole face was flushed as Katsuki smirked while petting his soft mass of curls. Sinking into his touch, Izuku sighed contently.

"Next year, we'll finally be out of this hellhole! No more All Might or Eraserhead. I'll finally be a pro hero and you'll be my personal bitch. Maybe my 18+ sidekick? Your quirk would be how many dicks you could fit in your fat ass, and how many times you can cum." Katsuki continued to blabber on about whatever came to mind as he laid Izuku down and started to kiss, lick and bite every inch of his soft, pale skin. The only response Katsuki would get would be the delicious moans that would slip past swollen lips. Getting off the bed, Bakugou admired his work.

"Look at you, hot and bothered just by some kisses... So sensitive, so pathetic." He sometimes felt a twinge of regret after saying somethings, but after hearing Izuku groan from him saying that, the feeling disappears. "You are useless when you haven't been fucked silly. My sweet, stupid Deku, needing a constant tug in the right direction. My lost little puppy..." A laugh bubbles out of Katsuki- not his coined sadistic one, but a light genuine chuckle. "Maybe I should get you a collar, and train you proper, leash and all." His hands were aching to explore Izuku's body, but it was delicious watching Midoriya squirm for friction.

"K-Kacchan, please~!" His voice could put musical quirks to shame, making it even harder for Katsuki to keep his hands to himself.

"Ah! What did I say?"

Midoriya made a noise of discomfort,"B-Bakugou-Sama.... Please, I need you."

"Fine. But only because you begged so well," he lied through his teeth, but he did this for Midorya. His disgusting pervert of a boyfriend. Out of anything, he had to have a humiliation and dirty talk kink. Good thing Katsuki was a sadist... to an extent.

His life had always crashed into Izuku's, which led him to constant temper tantrums and fights. He had hated his boyfriend's guts, but now that Bakugou was older, he realized that he didn't want to see Midoriya wreathing in pain; he wanted to see him debauched and moaning his name. So they worked out quite well.

Both of their cheeks were flushed, bodies sweaty, and still clothed. And it wasn't even the good part yet! Bakugou slipped his own shirt off and Midoriya followed lead. Both continued to strip, until they were naked. Sans shame, Izuku started to stroke himself, unpleased by the pace Katsuki set.

"Deku!"

Izuku stopped, shame all of a sudden manifesting again.

"You're not supposed to get to that stuff without me, y'know. Besides, doesn't that hurt without lube?" He asked, grabbing a bottle of lotion from his drawer.

Izuku shrugged,"Sweat." His overactive sweat glands had already started going overtime, making his hands and forehead slick.

"Shit." Katsuki froze.

"Huh?"

"Sweat. Shit! Deku, we're going to have to be extremely careful. Fuck! How could I've forgotten?!"

"What do you me- oh. Oh yeah."

Nitroglycerin.

Nitroglycerin sweat.

"I'm going to try my best not to blow you up but this is one of my first times actually doing the whole thing. I'm sorry if I burn you." He was unusually tender, genuinely worried for Izuku.

"I'm glad it's you, Kacchan," Izuku smiled as he pulled Katsuki down onto the bed with him. The two looked at each other with admiration, lust, and maybe even love.

"Uh, don't wanna ruin the moment, but  do you still wanna do this, 'sama'?" Izuku laughed, smiling like an idiot.

"Of course, asshat, I would've kicked your gay ass out on the curb a long time ago if I didn't," muttered Katsuki who was blushing more so than Izuku. "But now...."

"What?"

"You gotta stretch me, stupid. We can't get any further without it."

"Wait!? I thought-"

"It doesn't matter just- here! Stop talking and start putting lotion on your hands!" Katsuki was throughly embarrassed, but he'd be lying if he said he wasn't enjoying himself.

Izuku followed instructions as they were given, slowly inserting a finger at a time until Katsuki moaned. "I'm glad you're enjoying yourself, Kacchan."

"Ok, shut up. Now, take your fingers out, and start lubing up your dick." Instead of taking one finger at a time, all were gone in a blink of an eye. Katsuki sighed, irritated at Izuku's speed, and the sudden emptiness. "C'mon you're not jacking off, dipshit! Just shove it in already!"

"I wanna make sure there is enough; I don't wanna hurt you." His big emerald eyes were filled with concern, and Katsuki felt like he was shot.

"You're not going to break me, dickface, I'm not fucking porcelain. Just lay down, take your hands off your dick," Commanded Bakugou as he straddled Midoriya.

"What are you-! Oh!" Without warning, Katsuki lined up Izuku's cock with his ass, and slammed down. It was still so tight, and hot, but as good as it felt, both needed friction.

"Hang on, cowboy." Even through it was still painful, Katsuki started to pump his hips, starting a slow rhythm.

***

Both were panting, sweating, and definitely enjoying themselves- getting close.

"K-Katsuki," Izuku moaned, which joined the chorus of repeated 'Izuku's. "I'm going to...."

"Going to what, give birth?" Bakugou was still trying desperately to act like he wasn't enjoying this as much as he was, even though his own mouth continued to betray him.

"I'm going to-!" Without much warning, Izuku finished, the other still riding out the orgasm.

"You've got to be kidding me! You could've lasted way long-" he ate his own words as a pressure suddenly released in his abdomen.

"You were saying, Kacchan?"

"Fuck off, dicknuts."

"Love you too."
