Natsuki, a wife who can't give up on a child with her husband who became disabled in an accident. After many discussions with her husband and wife, her conclusion was "surrogate sex with her father-in-law Kiyoshi". I thought that she would be easier to love than a complete stranger, but Kiyoshi regained her vitality more than necessary in front of the young and beautiful Natsuki! Kiyoshi relentlessly pursues Natsuki's body, saying, "I'm lonely because I can't do it with him..." although it should end with a simple sexual intercourse. In front of the name of making her child, she does not hesitate to give her son's daughter-in-law many times. Natsuki was also drowning in her "sex with her husband-approved father-in-law".
