This is a stupid school with a deviation value of 30 at the very bottom. In particular, the four girls do not study or do club activities, and they can't help but spend all their time in SEX every day. Suddenly they are told that the school will be closed! !! Those who want to withdraw the closed school by any means establish a "SEX club" and persuade the officers with the erotic technology that they have cultivated so far! !! !!
