Several years into their marriage, the warmth between the Kamiha couple has faded, and even conversation has become scarce. Feeling lonely, wife Taiichika confides in her neighbor, Mrs. Tanaka, about her strained relationship with her husband. Tanaka then tells her about a popular in-home delivery service from a local liquor store that's been the talk among housewives. With her body aching from a sexless marriage, Taiichika impulsively decides to place an order out of curiosity. The deliveryman who arrives is Morita, a strong and confident liquor store employee. As Taiichika prepares herself mentally and physically, she trembles with anticipation and excitement for the intense experience about to unfold.
