“Hey, Kacchan? Can you come here for a second?” Izuku called. He was in the room with his door closed, and Katsuki was suddenly very intrigued. He put down the knife he was chopping vegetables with, pushing Izuku’s door open slowly as he walked inside.
“What do you want?” Katsuki grumbled. Before he could walk much further, he halted, taking in the ridiculous scene in front of him.
Izuku was standing in front of his full length mirror, hands on his hips. He was frowning, but Katsuki could see the embarrassed blush on his cheeks as Katsuki’s gaze dropped down. Izuku was only wearing Christmas boxers, which was embarrassing on its own. They were gray and covered in cartoony Christmas lights, and Katsuki would never be caught dead wearing them.
The second unfortunate circumstance was the fact that his jeans were stuck at his thighs.
“Listen, don’t laugh,” Izuku started. Katsuki chuckled, disregarding that statement immediately. Izuku gave him a look that should have been intimidating, if he was wearing pants. But as of right now, they wouldn’t fit over his ass, and Katsuki was going to laugh about this until the day he died.
“I can’t get my jeans up,” Izuku said. Then, he waited.
“So, what the fuck do you need me for?”
“To help me pull my jeans up.” Katsuki blinked.
“That kind of sounds like a you problem,” Katsuki said.
“I know, but unfortunately I need help.”
“But they clearly don’t fit?” Katsuki questioned, gesturing to the very obvious predicament. Izuku pursed his lips.
“They do. They’re just tight around the thighs,” he said. Katsuki did another scan of Izuku’s body, nodding almost unconsciously.
“Okay, and…” Izuku rubbed his face with his hands, an exasperated sigh coming from his throat.
“Can you just come here?” he asked, his voice muffled by his hands. Katsuki took a few steps forward, stopping about an arm’s length away from him. “I don’t bite.”
“Yes you do, you fucking liar,” Katsuki said, clearly remembering when Izuku chomped down on his arm when he tried to take the remote from him on one of their movie nights. He had literal indentations on his skin, and he wasn’t even successful in grabbing the remote. All around a terrible experience that he would not recommend.
“Okay, maybe I do, but I won’t right now. This is important,” he said, and Katsuki still could not take him seriously with his pants around his thighs like that (because it was stupid ).
“Why do you need jeans anyway, you’re not fuckin’ going anywhere,” Katsuki muttered, taking another step closer.
“Actually, I’m going to hang out with Shoto and Ochako. They wanted to go to a bar, and I have tomorrow off, so I said yes.” Katsuki didn’t comment on that. Instead, he glanced down at his pants again.
“Okay, you look stupid as fuck,” he said.
“You’re the one that’s not helping me!” Izuku cried desperately.
Katsuki huffed.
“I’m going to watch the next episode of our show without you,” he said saltily. Izuku’s eyes widened. The look on his face was similar to if Katsuki had just threatened to murder him and his whole family.
“Kacchan, no.”
“Kacchan, yes ,” Katsuki replied.
“How about, to compromise, we can watch two episodes tomorrow night,” Izuku said, sticking out his hand. Katsuki hesitated before shaking it.
“Fine.”
“I’ll be back before midnight.”
“I’ll beat your ass if you’re late,” Katsuki said, narrowing his eyes at him to show how serious he was. Then Katsuki remembered what he was supposed to be doing.
“Alright, how the fuck am I supposed to help with this shit,” he said, grimacing. Izuku motioned him closer again , and then tugged on the belt loops of the jeans.
“Just grab these and yank them up,” he said. Katsuki reached forward, holding onto the belt loops.
“Just, fucking yank them?” he asked, still unsure of what the fuck he was supposed to be doing.
“Yeah, like, as hard as you can.”
“Don’t blame me if this goes horribly wrong,” Katsuki said. And then he tried to pull them up, and realized that it was going to be more of a challenge than he thought.
“You should stop working out,” he muttered, and then he pulled them up again. He made a little progress. They were higher up his thighs than before, anyway.
“I like my thighs this big,” Izuku said.
“Your jeans don’t.” He pulled again, and this time, they were able to slide up and over his ass, the waistband resting comfortably on his hips.
He then realized how unreasonably close they were. He could practically feel Izuku’s breath on his neck. His hands were still on Izuku’s waist, and Izuku’s were on his shoulders. So close. The tension in the air was thick, and he wished he had the confidence to just break it. His own breath hitched, and all he wanted to do was dip his head down and just-
He backed away. Izuku grinned, turning to admire himself in the mirror for a couple of seconds before turning back to Katsuki.
“Thanks.”
“Whatever.”
Izuku turned again, straightening his tight black shirt out and smoothing out the invisible wrinkles. Katsuki took the time to admire his hard work, deciding that the struggle was worth the outcome.
“Okay, I don’t have to leave for another half hour,” Izuku said, checking his phone.
“I’m gonna… oh, fuck, Kacchan,” he moaned. Katsuki’s heart raced.
“What?” he asked.
“I have to pee.”
“You’ve gotta be fucking kidding me.”
“I’m not.”
“Can’t you just unzip the fly and stick your dick out?”
“They’re too tight and the zipper is too high up. I have to pull them down a little bit.”
“Are you fucking for real?”
“I’ve never been more serious in my life.” Katsuki pursed his lips.
“So, what, I’m gonna need to do this again?” Katsuki asked.
“Unfortunately.”
“What, you don’t want me that close to your dick again?” Katsuki joked, settling himself down on Izuku’s bed, waiting.
“That’s definitely not what I said,” Izuku said quietly. Katsuki almost missed it.
“What?”
“Nothing. I’m gonna pee, I’ll be right back!” And with that, Izuku sped into the bathroom attached to his bedroom and the door clicked shut behind him. Katsuki sat there, mildly stunned and confused. Should he dwell on it? Probably not. It was probably nothing.
He glanced down at his own lap and was displeased with the fact that he was turned on. He groaned, debating the consequences of bashing his head against Izuku’s bed frame.
Fuck him.
