The prostitute mother, the son who gets an erection when he sees the body of his new stepmother, flirts with Hinata as the opposite sex.

At first, Hinata treats him gently, but over the course of a month, he is conveyed with an air of likes and dislikes, and their hearts grow closer and closer.

While his father was on a business trip, lying in the sun at night, his son was scolded by his mother, but he was sucked by one hand, saying: "I just bear it". The next day, what did the mother do when her son asked her to let her have sex with him kneeling on the ground?
