The student council president, Arina, visits the neighborhood association's house to ask for their cooperation in the school festival. The middle-aged man is usually a town caretaker, but he is actually a pervert who is the organizer of the Sailor Suit Mania Club and has an abnormal interest in young women in uniforms. The president's friends conspire to blackmail Arina, peeping at her upskirts, sniffing her whole body, exchanging saliva, and playing with her pussy in all sorts of abnormal ways.
