Eight years into a cold marriage, Nami is approached by a man she barely recognizes: Odagiri, the childhood friend who had a crush on her twenty years ago. The awkward boy has grown into a handsome, muscular man. While her husband is away, Odagiri arrives soaked by the rain and Nami lets him use the shower. She accidentally sees the enormous cock that replaced the tiny one she remembers from their childhood baths. Overwhelmed by desire, she loses control and repeatedly gives herself to raw sex with him.
