Rei Kimura, a full-time housewife, has been married to her husband Yuji for two years. They were living happily until she injured her lower back while doing housework. At her husband’s recommendation, she calls a dispatched masseuse named Maeda for treatment. Although Maeda acts friendly, he lewdly attacks Rei’s body under the guise of treatment. At first she accepts it as necessary for her back pain, but she cannot resist the teasing massage with powder and oil, and pleasure gradually takes over her mind and body. Eventually Rei shows expressions she never showed her husband and is brought to climax again and again by Maeda’s hands, tongue, and cock.
