Takako, the mother, was once again being touched by her eldest son as usual. Though she was disgusted by such indecent circumstances, her dry, fifty-year-old body continued to sink into pleasure. Her younger son, expressing his desire by saying, "I want you to be only my mother," clung to her affectionately. Responding to his feelings, Takako cuts ties with her eldest son and grows closer to her younger one. She confesses that he is not her biological son, correcting the lies of the past, and begins a new relationship with him.
