In this adult school role-play, an adult male student discovers the stunning trainee health teacher Karin Tono masturbating in the infirmary after class, wearing a tight dress beneath her white coat as she fondles her breasts and traces her pussy through her panties. A noise exposes his spying, but instead of getting angry she begs him to keep quiet and offers to do anything he wants. She eagerly sucks his cock, admits that fantasies about sweaty adult male students fuel her masturbation, and invites him inside her. During her two-week training period, they secretly fuck in the infirmary while others remain at school, and she submits to his every demand. Long afterward, he still wonders whether she remembers him when she masturbates—or has moved on to another adult student.
