Beautiful girls do not have enough points in the Department of Sexual Activity! In this school, the ochidai students are supported by the whole school. Repairing SEX with rippling tide!

In 20×x years, the Department of Sexual Activity was introduced as an educational reform at a Japanese school site. Under the philosophy of spreading expanded sexual information to students as knowledge and experience, it became an educational system that means that if you do not take a certain number of points in the examination, you will stay for the rest of the year. The girl at the point where she dropped was a teacher and a student who helped her as an internship, and she looked embarrassed all over school until the end, so she learned something about sex.
