A boys' school where a female teacher conducts health and physical education classes. A new female teacher with a burning sense of mission who has been appointed without knowing it. She is persuaded by her senior teacher to "improve the quality of her lessons", and in confusion, her clothes and underwear are taken off, and her fresh body in her 20s is stripped naked. Bare pink nipples. Thin pubic hair. Using a dazzling female body, sex education is given to a male student who has a sexual desire.
