That JAV

In 20XX, a subject called "Sexual Activity Department" was introduced as an educational reform in Japanese schools. Under the philosophy of spreading sexual information as knowledge and experience to all students, the educational system was designed so that students had to score a certain number of points in an examination to be retained in the class. Girls who failed the exam would have sex with the teacher and other students who helped them as a practical training, exposing their shameful appearance to the whole school until they passed the exam and learned what sex was all about.
