Chaste housewife Mina in her second year of marriage. She lives with her kind and hardworking husband. Her only complaint was that her light-hearted husband wasn't very active in her nighttime marital life. In the next room of the same apartment, there lived a middle-aged man named Ikeda, a quiet, taciturn, and fierce craftsman. He is a neighbor man who always responds with a brusque whisper when he says hello. However, Mina, who is frustrated with her, gets her crotch wet with the smell of male sweat that he gives off. And then one day...!
