In a world where "practical sex education" has been implemented as a measure against low birth rates, students learn about sex through actual intercourse and pregnancy during school lessons. In this work, female teacher Hono Wakamiya uses her own body to provide direct guidance to one student after school. She carefully teaches where women feel pleasure and how to make them happy, allowing the student to touch, insert, and creampie, experiencing baby-making. The education is completed when the student experiences impregnation through pregnancy. Enjoy the wonderful sex education filled with lewd words and impregnation themes from the erotic body of Wakamiya-sensei!
