Beautiful housewife Mami supports her husband, a system engineer. With the increase in remote work, the couple enjoyed more time together, living happily—until a critical issue arose in the financial system he managed, forcing him into consecutive business trips to clients. Taking advantage of his absence, Mami's boss begins visiting, demanding her body as compensation for covering up her husband's failures. Enduring it all for her husband's sake, Mami becomes increasingly sensitive under relentless nipple play, writhing in ecstasy from deep vaginal creampie after creampie. Her body, now trained to climax through nipple stimulation, can never return to how it once was.
