- Part 1 of the movie is the story of Maika, a girl who lives with her artist husband, but because his paintings cannot be sold, both of them have a very difficult life. After many ups and downs with her useless husband, Maika had to come take care of his sick old father. Even though the old father was lying in one place, he still craved the sight of his daughter-in-law's tender body. The old man promised to give his daughter-in-law a sum of money if she agreed to have sex with him. Because she wanted to help her useless husband, Maika agreed with her eager father-in-law. - Part 2 is about the filial daughter Yu Kawakami who has to take care of her sick old father. She helps her with all the father's activities, including sex, perhaps her filial heart and pink braid. The daughter's pride helped motivate the father, from a paralyzed old man suddenly becoming strong and fierce like a buffalo goring into the grave. - Part 3 is also the last part of the film about the unfortunate wife Sayuri Senaha. Because she unfortunately married a husband with weak physiology, she often had to lie down and masturbate alone during long nights. One day she invited a colleague from the same company to her house to visit. Senaha had prepared a party for her colleague with champagne and fruit as side dishes, and the main dish was her tight pussy and plump pink breasts. Surprised by the host's enthusiastic reception, his colleague got drunk and enjoyed this sensual party.
