The presidents of many clubs at school are begging the student council president for money, but she can't give it to all of them so she goes with them to another room to "discuss" the matter.Hasegawa-kun, her secretary thinking it's his duty follows her, peeks in the room from a hole in the wall and sees his beloved president having sex with all of the clubs presidents. After a while she calls him in as well and so more and more people get involved in the story.
