After the death of his mother, Kaito's father remarries, and Kaito himself goes crazy about his sexy new stepmother, Saioko, in which an incredible female passion rages. It's good when a real beauty comes to the house instead of going to look for her who knows where. And it does not matter whether she is your stepmother or not. For Kaito, it does not matter. Knowingly distraught with thirst, Kaito soon begins to spy on her and sneaks into her bedroom for some secret night action. Although tormented by some guilt, Saioko eventually turns out to be a willing participant. And when Caito tells her that his father is cheating her with the younger woman, they start coming together very quickly. For Kaito it does not matter what his dad will be left alone again. He rather spit on it. If his dad knew that everything would turn out that way and that his "little son" could be so dangerous !!! He's poor! He would not bring his stepmother home. Sex, sin and betrayal will turn Katoe's whole household upside down!
