The teacher asks Akiyama, a geeky, bespectacled boy, and Ieda, a popular jock, to visit Noriko's house because she's been absent from school for some time. Akiyama and Ieda find Noriko, a pretty girl, alone at home. They assume Noriko hasn't come to school because she has a bad cold, but to their surprise, it turns out that she has another type of illness -- she can't stop thinking about sex. Before Akiyama and Ieda realize what's happening, Noriko demands that they have threesome. This intimate act bonds them as friends.
