A married woman, Yuko, whose husband was a long-time bachelor who had transferred schools, lived with her son, a university student. Although she was happy, perhaps because she was lonely because she could not see her husband, she was somewhere in her heart searching for stimulation. One day, she was raped by a friend of my son when she came to pick up something he had forgotten. From that day on, my daily masturbation habit disappeared. My son's friend's demands escalated and became more and more intense. A married woman was played by a young man and gradually wavered between guilt and pleasure.
