Her husband is an eccentric man obsessed with lactation play, so Minako leaves her child at her parents' house and devotes herself entirely to fulfilling his desires. Overcome with jealousy toward her own child, he begins to feel like a child himself. Every morning before commuting to work, they engage in lactation play, which gives him energy for the entire day. After seeing her husband off to work, Minako feels a throbbing sensation in her breasts, and the moment she spots a male visitor, her desire surfaces immediately.
