A world where "practical sex education" exists, which was introduced as a measure to combat the declining birthrate. It is a new type of sex education where men and women actually learn about sex by having sex to make babies and getting pregnant. In this work, homeroom teacher Hibiki Otsuki calls in students who have refused to come to school and uses her own body to directly teach them about creampie sex... She carefully teaches them which parts of a woman's body are sensitive and how to please them, and lets them actually touch, penetrate, and creampie her to experience making a baby, and then the education ends when they report that they are pregnant.
