Rieko has been married to a man with a child for three months. She has a good relationship with her husband, but she still can't open up to her son Kazuya. Seeing that it's not working, her husband suggests that the family go on a trip, but... Kazuya, who has begun to feel Rieko's charm as a woman, pushes her down, unable to suppress his intense desire. Rieko, who repeatedly climaxes with a piston that chews and caresses endlessly. Kazuya's excellent compatibility with SEX that I've never tasted before can't suppress the pain in my body.
