The ultimate offering from Shinsei Dramax: the adulterous eros of a desire-driven gal wife, challenged by Mami Nagase! Yuuta moves to Tokyo to attend university and starts living alone, but soon faces a water outage at his apartment. He ends up staying with his brother's family in the city. Mami, his sister-in-law, takes an interest in her young brother-in-law, Yuuta, and begins to seduce him gradually! Driven mad by the allure of his big-breasted gal sister-in-law, their adulterous acts escalate, and she writhes lewdly, moaning wildly as they engage in illicit sex.
