A married woman, Yuko, whose husband is a long-time single transfer, lives with her son, a university student. Although she was happy, perhaps because she was lonely because she couldn't see her husband, somewhere in her heart she was looking for stimulation. One day, she was raped by my son's friend when he came to pick up something he had forgotten. From that day on, my daily masturbation habit disappeared. The demands of my son's friend escalated and became more intense. A married woman is flirted with by a young man and gradually swings between feelings of guilt and pleasure.
