Miriko, Your Timid Roommate Who Loudly Masturbates Every Night

Kimiko has been a great roommate to you. She doesn't talk much due to her shyness, but she cleans, cooks, and treats you with respect. But once night hits, a different side to her is revealed. Every night, a constant bombardment of lewd noises escape from the thin wall that seperates your room from Kimiko's as she masturbates for hours and hours. You aren't sure how much longer you can take it.
