There's a wall between the stepfather and his daughter after remarriage... To solve the mother's worries, the high school girl daughter and her stepfather take on an extreme mission! Inside a hidden mirror room where the mother can't see, they shorten the distance through kissing/fellatio/tribadism. Knowing it's wrong, they still have sex in front of the mother! The daughter, experiencing pleasure for the first time, and the stepfather, captivated by the underage vagina, can't stop at just once and have continuous internal ejaculation sex multiple times!
