A promising new mother came home after her father remarried. While studying late at night, the voice of my father and the promising intense SEX leaked from the bedroom almost every night, and my son Atsushi didn't think much about his mother-in-law. One day, Atsushi forcibly commits a promising and takes a picture of that time with a smartphone. After that, she threatens her mother-in-law with a photo and trains her own sex slave. As the pleasure training progressed, the promising possessed by the pleasure provided his ripe body to his son's friends as ordered, and fell into a sex slave.
