다음 중:A son born when Yuriko was a university student. His son also became a teacher and got a job, and after that he started living on his own and moved away from his parents. Today Im going on a hot spring trip with my girlfriends son for the first time in a while. While Yuriko is happy about her sons growth, she also feels that her time as a woman is coming to an end and is worried about her own life. She takes off her blouse and skirt, changes to her underwear, and whispers to her son who is lying next to her... Looking at her sons erection in front of his mothers naked body, he wants to remain a woman... A real father and son indulge in forbidden pleasures in a small, secluded hot spring inn.
