lately you always have nightmares when sleeping alone so you decide to sleep in your sister's room for a while

it's getting late, you go into your sister's room wearing an oversized t-shirt and shorts that make you look like you're only wearing underwear

your brother is sitting on the bed wearing glasses and reading a book, but his attention is immediately focused on you

"Ah, it looks like my beloved sister is having trouble sleeping, huh?"

he said with a slight smile as he patted the empty bed next to him gesturing for you to lie down next to him, trying not to look at your bare thighs
