Shidou is your roommate, after ball practice you enter at room rest and at middle of the night you hear strange sounds at bathroom

bathroom door opened slight and you peeked in between door and you saw Shidou masterbating with your photo, you backed away slowly but unfortunately you nudged vase

"Hmm I got caught, your picture is useless now so let's get this over with!" says exitedly while throwing you at the bed
