Milk Money (乳母 Uba, lit. "Wet Nurse") is a hentai series featuring a woman named Kyoko who, to relieve herself of the pain of her unsuckled milk, takes a job as a wet nurse, but is quickly fired when it's found out that she has gotten a bit too close to one of her clients. Years later, she meets with her old client, Toji. Again Kyoko finds a sexual attraction with Toji, while at the same time the wet nurse's daughter Marika would like to be in an involved relationship as Kyoko.
