Mid-argument, Izuku looked startled and stared off into space.
Bakugou started speaking, but got a whole hand in his face with an absentminded “shh-hhh.”
“...the fuck?” he batted the hand away.
“Shh, I'm thinking.”
“Well spit it out, nerd.”
After a moment more thought, Izuku continued. “I think you like this.”
“Like what?”
“Fighting.”
“Obviously I like fighting. I'm the best; can't stay the best without a little conflict.”
“No, I mean you like fighting with me.”
“It's alright I guess. You're still a dumb weakling, but squashing bugs is good practice too.”
“No no, I mean you like fighting with me. Not just winning.”
“I'm always gonna win.”
“Mm, maybe. But I have another theory.”
“......”
“I think maybe sometimes you don't want to win.”
“The fuck? Of course I want to win.” he stood and tried looking menacing.
“Sit down; I'm not done.” Izuku’s hand landed on his shoulder and pushed.
Katsuki growled.
Izuku snapped from distracted to laser-focused in an instant. “Sit. Down.” he spat the words like fire.
Katsuki sat down.
“Hmm…” the look on Izuku's face hadn't changed from intense focus, nor had he moved the hand from his shoulder. “Kacchan, I know you're stronger than me.”
“Damn right I am,” he grumbled.
“Don't interrupt. I know you're stronger than me, and I know you don't usually pull punches.”
“Usually? I never go easy; what the fuck are you talking about?”
“Kacchan, I said don't interrupt.” He stepped closer to loom a little over Bakugou in his chair. “You don't usually pull punches. But you also don't break my arms with your blasts. You don't shatter my knees with your kicks. When we spar outside class, you never do anything that would seriously hurt me, even though we both know you could, and Recovery Girl could heal me.”
“Bullshit.”
“I think,” Izuku talked over him, “you do that on purpose, so we can fight longer. I think you like playing with me. And I wonder…” Bakugou’s dismissal died halfway out of his mouth when the hand on his shoulder ghosted over his collarbone and Izuku's thumb brushed his throat. “I wonder if you want me to win sometimes.” That thumb kept circling, reaching farther across until both thumb and fingers were laid softly across his throat.
Katsuki's face was on fire. He couldn't breathe. Was he suffocating? No, the touch wasn't restrictive, it was just… there. Izuku's thumb was lightly petting the pulse jackhammering through his veins. Izuku was petting his neck. And he wasn't stopping him.
This wasn't combative contact. He should yell. Should scream. Push him away, call him names, something. Anything. But the only sound that emerged was a rather undignified squeak.
Izuku giggled. “You're cute, Kacchan.”
That broke the spell a little, and he was able to retort. “You tryin ta make me look weak or something? I'm not afraid of you, Deku.”
“I told you not to call me that, Kacchan.” His gaze turned dark, and then contemplative. “I wonder if you want to be punished? Hmm, or maybe just…soft. Do you want that?”
“Do I want what, nerd?”
“This.” He stroked his fingers across Katsuki's neck and up his jaw, leaving a trail of goosebumps and a shiver.
“Why the hell would I want that?” Katsuki asked through clenched teeth.
“Because it feels nice. Doesn't it feel nice?” He did it again.
“Don't care.”
“Oh, so it does feel nice? I thought so. You're always so rough, Kacchan. Always so in control. Maybe you want to let go. Let someone else be in charge for a while, hmm?”
“What the fuck are you talking about?”
Izuku had gotten closer as he spoke, standing between Katsuki's knees with his face angled down just enough to see his eyes. Bakugou was forced to crane his neck upward if he wanted to maintain eye contact and a semblance of control. The caresses at his pulse point hadn't stopped.
“What the fuck are you doing, shitty De-Izuku.”
“Mm, good catch there Kacchan. Do you want to be a good boy?” He watched as Katsuki's eyes dilated slightly. “Or do you want to be punished?" Izuku's free hand snaked around and twined through Katsuki's hair. He pulled.
Katsuki's eyes fluttered shut and he honest-to-goodness moaned. Shocked, his eyes flew open and he tried to stand. He failed. “What the fuck?! Are you trying to make me look like a bitch?”
“Kacchan, I'm not trying to make you look anything other than satisfied.”
Temporarily mollified and a little confused, he stopped struggling to stand.
Izuku's hand moved from neck to jaw, and he leaned even closer. “I'm going to kiss you now, Kacchan.”
The sweet smell of nitroglycerin filled the air, and both boys noticed a complete absence of explosions or arguments. Time seemed to stop as their lips met.
Immediately everything sped up into a flurry of hands and mouths and tongues and teeth, transforming from tentative touches to unleashed animal need. Izuku groaned along with the chair as he let his full weight grind into Katsuki's lap.
An ominous *creak* and a large *thump* landed both boys in a heap on the floor, laughing between combative kisses and struggles for dominance. It was a very long time before any homework was completed.
