Saori is a mother with two sons. Because his younger brother was sick, Saori treated his older brother Kiyoshi roughly and was concerned only with his younger brother. Kiyoshi begins to feel intense jealousy for such a mother and caresses Saori's body as she desires, "I want to make my mother my own ...". Then, the feelings of Saori, who was forcibly deprived of her body by her son, also changed.
