Fitch presents the debut of Miyu Yaninagi, a charming married woman with soft, voluptuous G-cup breasts and a lovely smile. She moves in next door to the protagonist, who works as an art school instructor, and quickly begins exuding irresistible pheromones. Once his former student, she now lives alone while her husband is away on a work assignment, allowing her to gradually reveal her feminine allure while helping around the house. As he assists her with moving, the protagonist repeatedly touches her body and even forces her into lewd poses as a nude model—engaging in constant sexual harassment. He continues to assert control, giving her electric massager treatments and making her call her absent husband during intimate moments. Their relationship deepens through these acts, paving the way for increasingly erotic developments.
