That legendary project resurrects after a long time in the modern era! The first commemorative revival is set on the ironclad situation of school and home! Even the principal, homeroom teacher, students, siblings, parents, and children are trapped and have live sex! During class, in the faculty room, student council, family breakfast, son's college entrance celebration party... everyone casually has sex anywhere. Enjoy this world where the barriers to sex are abnormally low!
