Mina Sugita, 34 years old. A mother of one, working as an apparel store clerk at a shopping mall. Her irresistible, voluptuous H-cup figure draws the attention of fathers visiting with their families, and she constantly feels their intense gazes during work hours. Now in her fifth year of marriage, her intimate life with her husband has gradually diminished, triggering a sense of crisis as a woman—and leading her down the path of infidelity. She once before was approached at work, giving in to pleasure after closing time. Using social drinking events as an excuse, she seeks thrills and forbidden excitement with men other than her husband. That single act of betrayal shook her rationality as a wife, and now she repeatedly chases ecstasy with her highly sensitive, lustful body. Even the slightest touch of a finger can make her squirt, a gesture that only intensifies her deepening desire.
