Hayato was stuck between a rock and a hard place, the rock being Kashima's body pressed flush against his and the hard place being his raging erection.

He always hated sleepovers in general but he hated them with Kashima most of all. Not for the same reasons, of course. Anyone else was a nuisance, always so noisy and nosy. Kashima wasn't like that at all. Honestly, Hayato wouldn't have minded if he was a little bit more curious, but he always gave him his space, never got too excited, making sure his company was always peaceful and relaxed…until bed. Until he went to sleep, mistook Hayato for his brother, and snuggled up to him all night long.

It wasn't so bad the first couple times and Hayato couldn't put a finger on when exactly this quirk turned into a problem. It just seemed like all of a sudden he couldn't stop listening to Kashima's quiet breathing and was too aware of the leg flung across his and the arm around his chest and also he mumbled in his sleep and was too restless and the sensation of his body shifting against Hayato's as he got comfortable was really—

Okay, probably shouldn't think about it more than necessary. Hayato was already wide awake at four in the morning and knew he wouldn't be getting back to sleep any time soon. He just needed to wait another hour before Kashima inevitably woke up at the asscrack of dawn and Hayato could finally doze off.

It was just that, at this point, Hayato thought about these things outside their sleepovers. Touching him, kissing him, doing things to make Kashima as unbearably restless as he made Hayato. He got the urge in the daycare room and the classroom and the bathroom and the locker room and the stairwell and, well…everywhere. He'd never been interested in romance before and Kashima was the first person he'd ever been attracted to. He didn't know what to do with it. That Kashima was male didn't bother him; Hayato certainly wasn't the only guy in their year with eyes for him. Actually, he shouldn't think about that, either. It just made him angry. He might not know what he wanted to do with Kashima (except he was pretty sure he did), but he did know he didn't want anyone else doing something with him.

Kashima sighed, his breath whispering across Hayato's collarbone, and shifted even closer. He was practically on top of him. It wouldn't take much more for Kashima to straddle him, back arching as he rode him, moaning and panting and begging—

I'm about to lose my whole mind.

Hayato sat up, forcibly breaking contact with Kashima before he did something he'd regret. He glowered down at Kashima's peaceful face, staring hard at his mouth, and pinched his cheek just to annoy him.

"Give me a break, dummy," Hayato said. "I'm not your brother."

But there was no sense in arguing with a sleeping idiot, so Hayato swung his legs over the bed and went to the bathroom to deal with his business. At this point he wouldn't be able to make it another few minutes, much less until sunrise.

"Who holds his brother like that, dummy?" Kashima mumbled into the pillow, but Hayato had already closed the door.

Well, there was always next weekend.
