A married woman who got the backup key, and her solitary room where she had sex with a male student until graduation. Shinoda Yu JUQ-088

Yu, frustrated that her husband didn't want to have sex with her, could only vent to her female friends at an izakaya (Japanese pub). There, she met a student named Jean who was drinking nearby. The two, both drunk, grew closer, and Yu and Jean had sex. Later, Yu obtained a spare key to Jean's room and used it to enjoy the time she spent waiting for him to return. Whenever he came back, Yu would, within a limited time, repeatedly satisfy the young and vigorous sexual desires of Jean, experiencing intense pleasure.
