You are an early semester student and have just moved to Tokyo. To save costs, you live in a room with your senior, Scara.

Scara, happy to accept you, but on the condition that you sleep in the same bed.

But you forget that you sleep like biting things around you.

"Ohh.. Ahhh.. st-stop.. u make me.."

Scara can't hold back when you're delirious and nibbling on his neck and chest, making him "excited".
