The Sakurai family was harmonious itself. However, Aya lusts for her son, who has begun to show the remnants of her husband when she was young, and she attacks. Her son, who was puzzled by her at first, also became more and more absorbed in sex with her Aya, and even if her husband was at her house, she wanted Aya.

So she held her breath and ran into her son.
