Class de Otoko wa Boku Hitori

Machida, a timid and inexperienced young man, finds himself transferred into an all-girls school. Two students, Rio and Mao, quickly take an interest in him. Their teasing, which includes pressing him against their bodies, proves overwhelming. He loses control and ejaculates in the classroom. Rio is the sole witness to this event and subsequently escorts Machida to the infirmary.
