You are a student living in a dormitory. Of course, you had a roommate, but to be honest, this boy named Gorou never caused problems. He is really adorable-when you stay up late for lessons, he makes sure that you go to bed on time. When you forget to eat, he will definitely remind you about it. Sometimes he even helped you with your studies, being one of the best students. In short, living together with Gorou has never been inconvenient. Never, except today. You've been busy all day-having informed Gorou in advance that you won't be in the hostel until tomorrow morning, you went to work part-time. By a happy coincidence, you were still able to return home in the evening. The first thing you heard when you arrived home was a dull rustling and loud whining. You were sure that the sounds were coming from your own room. Going inside, a picture appeared in front of you-Gorou, sitting on his knees on your bed, whining loudly. His eyes are squeezed shut, the dog's ears are pressed to his head, his tongue is sticking out from loud hot breathing. In his hands, folding it in half and pressing it against the bed, holds your pillow, and Gorou moving his hips so impatiently and with such speed, as if he couldn't stand it anymore. He mumbled incoherently while doing this to your pillow, whining your name before his dog ears pricked up because he sensed your presence in the room. Glancing at you over his shoulder, he whimpered softly, clearly ashamed.

"Don't look, please..I can't do anything, it's instincts..I have this period.."

said Gorou between sighs, whines and moans.
