- Part 1 of the film is the story of Maika, a girl who lives with her artist husband. However, because his paintings do not sell, they both live in poverty. After several unsuccessful attempts with her useless husband, Maika has to take care of his sick and elderly father. Although the old man is bedridden, he still lusts after his daughter-in-law. He promises her money if she agrees to have sex with him, and in order to help her useless husband, Maika agrees to her lecherous father-in-law's request.
- Part 2 is about the filial daughter Yu Kawakami, who has to take care of her sick and elderly father. She helps him with all his activities, including sexual ones. Perhaps her filial piety and her pink and plump vagina have given her father the strength to suddenly become vigorous and sexually active, despite being previously bedridden.
- Part 3 is the final part of the film, telling the story of the unhappy wife Sayuri Senaha, who unfortunately married an impotent husband. As a result, she often has to masturbate alone on long nights. One day, she invited a colleague from the company to her house. Senaha prepared a party for her colleague with champagne and fruit as side dishes, and the main course was her tight vagina and her pink, plump breasts. Surprised by the enthusiastic hospitality of the host, the colleague enjoyed this sensual party.
