Mother and son have sex in 2 seconds after father goes out

From the day he crossed the line with his son Yoshio, Kaori had been living a life of using two faces differently. She is as good a wife as ever before in front of her husband. A perverted woman who devours her child's carnal desires when she goes out. This is not good... Even though I knew it in my head, Kaori's body was so indulging in her relationship with her child that it was impossible to turn back. Today, Kaori plays a good wife, and while thinking about her affair with her child, she wets her crotch and waits for the moment when her husband goes out.
