High school seniors arrive at a local inn for their school trip. Nami, a serious honor student, is appointed as the "sex duty" monitor to keep an eye on the adolescent boys and make sure they don't go overboard. She keeps a sharp eye out to see if they have any erotic materials, act strangely, or cause trouble. As expected, Nami discovers and confiscates an erotic magazine. The boy who lost it is driven wild with desire and begs Nami to jerk him off. Because of her kindness and inability to say no, she gives in and jerks him off, which triggers a chain reaction of erotic incidents breaking out everywhere. Eventually, it escalates into a massive orgy with everyone participating...
