Miwa Sugita, 34 years old. A mother of one who works as a clothing store employee at a shopping mall. Her voluptuous H-cup body, which she cannot hide, is the object of desire for fathers with families, and she often feels their heated gazes during work. As she approaches her fifth year of marriage, her nightly activities with her husband have dwindled, and her sense of crisis as a woman drives her down the path of infidelity. "Once before, during work, I was invited..." She lies about going to a drinking party and experiences the thrill and guilt of pleasure with a man other than her husband. A single mistake sends her wife's reason spiraling out of control. An H-cup busty wife with a sensitive, lewd body that squirts from a single finger seeks the pleasure of that day and comes over and over.
