Rieko has been married to a man who has a stepchild for three months. She has a good relationship with her husband, but she still can't open up to her son Kazuya. Unable to see it, her husband proposes a family trip, but... Kazuya, who has begun to feel the charm of Rieko as a woman, pushes her down without being able to suppress his high desire. Rieko who repeats the climax many times with a chewy piston and relentless caress. Kazuya's excellent compatibility with SEX that I have never tasted before can not suppress the pain of my body.
