In recent years, serious problems of school absenteeism, declining academic achievement, and the declining birthrate have been addressed, and as a result, national educational institutions have introduced a system of creampie duty. It has been proven that by instantly relieving students' sexual desires, it is effective in "increasing concentration on studies" and "increasing sexual experience and understanding." Girls who are assigned to be creampie duty in each class wait in "creampie spaces" partitioned off all over the school, and students who wish to do so are allowed to creampie during their turn. At first glance, this system may seem unfair to girls, but the girls who have experienced the pleasure of creampie sex have accepted it and are enjoying it just as much as the boys. This is a dream system where everyone can experience creampie sex happily!
