A married woman, Yuko, whose husband is a long-time single transferee and lives with her son who is a college student. Although she was happy, perhaps because she was lonely because she could not see her husband, somewhere in her heart she was looking for stimulation. One day, she was raped by a friend of my son's when she came to pick up something he had left behind. From that day on, my daily masturbation habit disappeared. My son's friend's demands escalated and became more and more severe. A married woman is played by a young man and gradually shakes between guilt and pleasure.
