Chapter 1: Chapter 1
Luciferus was lying in his bed in his room, wearing booty shorts that showed off his ass, and an old torn oversized shirt. Katsuki walks in and sees his little brother, his cute ass on display, and shakes his head saying,
"Dude, cover up i can see your ass, and your underwear."
He chuckles, pretending to play it off, his dick twitching to life in his pants. Katsuki knows damn well he's glad Luciferus is showing off his ass, he wants nothing more than to touch his little brother inappropriately.
"Hey, there sleeping beauty," Katsuki said, leaning against the doorframe of their shared room. "Are you still asleep?
"Nope"
"It's raining outside, don't you like rainy days?"Luciferus shifts on his bed, his ass sticking up in the air.
"I don't like them when I'm fucking tired as hell. What about you?"
"I love them. They make me feel safe."
A smile crawls up Katsuki's face, he can't help it.
His little brother is so damn cute, he could just melt. 'I wonder what he looks like under that shirt...' he thinks to himself.
"Well, I have to go now, I have work to do before the rain starts to get heavy."
Luciferus nods, Katsuki's dick twitching in his pants once again.
"Later, bro. Sleep well."
Katsuki smiles, his eyes lingering on his little brother. He wants to see him naked, badly. 'Fuck, I need to see him naked.' Katsuki thinks.
