Nell tries to enroll in a prestigious girls' school while hiding the fact that he is a boy. However, during a physical examination by the health teacher, he is found out to have lied about his gender. The teacher finds out his weakness and uses him as a toy for SM training. He uses a nipple suction device to enlarge his nipples like a woman's. Even during his punishment, his penis becomes erect and he is blamed for not showing any remorse. He is made to spread his legs on the delivery table and his anus is expanded with an extra-thick dildo. The perverted boy who orgasms multiple times is declared a masochist and used as a sex toilet by the teachers!
