Bakugou Katsuki, predictably, was out of his element in water. He could run for miles on a hot day, sweating until he was disgusting. He savored a scalding hot shower, strangely enjoyed the smell of the smoke he created.
He wasn’t a swimmer. He didn’t like the beach. There was something dangerous about water, maybe that it made him useless, rinsed off all the sweat he needed for his Quirk. Maybe he didn’t think of himself as fluid, clean.
He couldn’t explain why he craved that danger. This made for a difficult conversation when he finally brought it up with Midoriya.
“You…. you want me to what?”
“Are you really gonna make me fucking repeat myself? I want you to drown me while you fuck me.” Bakugou stared into Midoriya’s eyes, unwavering.
“Isn’t that going to hurt you? I mean, I know that you like that kind of thing but I didn’t think that you were going to ask me to uh, sexually murder you?”
What a fucking idiot. “Don’t kill me, fucking dipshit Deku. It’s the same as when you fuck my face or choke me! You give me a fuckin’ break or listen when I tell you to stop. I’m not a dumbass.”
None of those things were comfortable to Midoriya, even more uncomfortable when he found himself liking it. It’s like Bakugou had a microscope to the dark, small places in his brain, where his selfishness lived, his sadism. He had just come to terms with how aroused he was with Bakugou’s throat closing around his cock — how was he going to justify this one? “Okay, uh, when do you want to try it?”
Bakugou grinned and Midoriya knew it would probably be worth it, just to make him so happy. “That’s more like it, nerd.”

Midoriya didn’t love bathroom sex, not even sharing a steamy shower if they were going to fuck. Too many hard surfaces, danger of slipping, accidentally washing away lube…. he much preferred the comfort of a real bed or maybe the occasional couch. He was sure Bakugou was going to regret some part of it, his chest or stomach on the edge of the slowly filling bath, his knees against the tile, even with a towel beneath him. At the very least, it was going to be a mess.
Bakugou turned off the water. It wasn’t steaming. Was it lukewarm on purpose? He stood to face Midoriya, their lips almost touching. “I’m ready for you. You ready to fuck me up, Deku?”
Midoriya took a fistful of his hair, pulled his head back like they’d practiced again and again. He bit Bakugou on his shoulder, hard, and was rewarded with a slow moan. He never would have thought of himself as someone who enjoyed this kind of sex, rough to the point of painful, degrading, but watching Bakugou go hazy with pleasure was a delicious thing and he was indulgent.
“Remind me, Kacchan, who do you belong to?” Midoriya followed the bite with a soft kiss, gently licking the bruised skin.
“You, Deku.” And then Bakugou was on his knees.
“And what do you want me to do, Kacchan?” Midoriya stroked his hair, sliding his hand down to Bakugou’s chin and gently lifted it up. He took in this sight, his favorite. Some part of him still remembered all the times he was on the ground, looking up at Bakugou, his childhood friend, his bully, his rival. He’d be lying if he said he didn’t enjoy the change of pace.
“I want you to fuck me, Deku. I want you to make my fucking lungs burn.” It turned on something wicked inside of him, anticipating submission. He was already hard, despite kneeling on cold tile and having barely been touched. He opened his mouth. An offering.
“If you want something you need to ask nicely, Kacchan.” His expression was gentle, which seemed patronizing here.
Bakugou swallowed. “Please, Deku, will you fuck my face with your cock?” He opened his mouth again, tongue out.
Midoriya pushed his cock between Bakugou’s lips, savoring his warmth and wetness. “I forget. Can you show me how?”
Bakugou swallowed Midoriya’s dick, exhaling as he took the full length of it, all the way to the top of his throat. He stayed there, clutching Midoriya’s ass to pull him closer. He didn’t break eye contact with Midoriya, eyes burning and tears already starting to pool. He pulled Midoriya all the way out by the hips, took in a deep breath before sucking him in again. He held his face still as he thrusted Midoriya’s cock into his throat, until Midoriya gripped his head and moved it for him, matching the movements to his thrusts. Bakugou had a talent, didn’t mind the burning in his throat, could hold down his stomach even when gagging viciously. His throat clamped down on the head of Midoriya’s dick and it was too much and Midoriya pushed him back, motioning for him to flip over.
Bakugou shifted into his hands and knees, forearms up on the edge of the bath. He lifted his ass, glancing over his shoulder invitingly. Midoriya straddled him, apprehensive.
“Kacchan, you have to wave if you want me to stop.” Midoriya rubbed his back tenderly, then squirted a dollop of lube onto his finger. He swirled around Bakugou’s asshole, then pushed his finger in slowly. Bakugou let out a breathy fuck yeah…. as Midoriya worked the lines around inside of him. He wanted him so badly, wanted to slam into him right away, but he was patient. He lubed up his cock, rubbed the head against Bakugou’s entrance. “Ready?”
Bakugou nodded, letting out a sharp inhale that he would regret as Midoriya pushed into him and simultaneously pushed down his head. Bakugou clenched, impossibly tight around his cock and Midoriya swallowed. He really would end up liking this. He held Bakugou down, not moving, then let go. Bakugou breached, sucking in air. Midoriya pulled back until he was almost outside of Bakugou, then pushed in all the way again, slow and deliberate. Water dripped from Bakugou’s hair down between his shoulder blades and he looked irresistible , so perfectly erotic he veered into pornographic territory.
Midoriya quicken his pace and dunked Bakugou’s head down again. He wanted to see how long Bakugou could last, how long until his stubbornness was broken by physical need. One hand right around the back of his neck, the other gripping his hip and both helping him thrust harder, Midoriya panted, lightheaded from pleasure. It felt like far too long passed before Bakugou started to push up against Midoriya’s hand and started waving. Midoriya held him down for three more seconds, then let go.
Bakugou pushed himself up, nose and throat on fire. He heaved up water, coughing and spluttering. The world came back into focus and he gasped in huge inhales. He felt delirious, falling into getting fucked, into the blissful, mind-blank space of submission. He let go and begged for more. And Midoriya gave again, as he always did, and sound faded away as Bakugou was pushed underwater again. He held his breath, mouth open as he felt Midoriya thrust into his slick asshole again and again. He wanted two mutually exclusive things. He wanted to pant, moan, cry out so Midoriya could hear just how good he felt, how full he felt. He wanted to stay there, underwater, breath escaping him in fat bubbles. He shut his eyes, overwhelmed. He opened them again and black spots formed in his vision and he pushed up with both hands, but that was the wrong gesture and he was held firmly in place. What was it again he was supposed to do? He was convinced he could die there, succumbing to Midoriya’s whim. A glorious place to invite in that darkness…
He finally waved when he felt his consciousness start to slip and he leaned his hips back to signal he was done, he couldn’t handle it anymore. Midoriya bent to kiss his shoulders, didn’t relent. “I’m going to cum inside you, Kacchan. I’m so close. You feel so good I’m losing my mind. Is it fucked up of me to love doing this to you, ah, ah, mmmm…”
Midoriya came, hot liquid filling Bakugou’s ass. Midoriya pumped once, twice, then pulled out, watching his cum drip down his taint. He pulled Bakugou to his knees and turned him around. He was sopping wet, his face red, his mouth still open, his chin covered in spit. Midoriya felt a twang of guilt, reminded himself that Bakugou had asked for this, had let him know that it wasn’t too much. “I want to watch you touch yourself, Kacchan.” He said, lowering himself until he was sitting on the floor.
Bakugou loves to do this for him, still a little bit full of himself and eager to make Midoriya desire him. He leaned back so his entire body was on display, perfectly aware of how the water accentuated his toned body. He didn’t look away for a moment as he finally started to stroke his cock. He was already so close, having not been touched until now. He came too quickly, cum joining the water on his stomach.
Bakugou sat there on his heels in a puddle, goosebumps rising on his skin. Midoriya leaned forward, kissing him gently, all soft lips. “Good thing we can clean you up, right away, honey.”
