The Sakurai family was a happy place. However, Aya becomes aroused by her son, who is starting to show signs of her husband's youth, and attacks him. Her son is confused at first, but he gradually becomes more and more absorbed in sex with Aya, and begins to desire her even when her husband is at home. Even Aya tries to scold her son, but she can't help but get wet at the situation - "with the three of us sitting around the dinner table..." and "while my husband is working..." and she holds her breath as she has sex with her son.
