When Yuko Ono and her husband move from the countryside to the city for his career change in town with Odagiri as their new neighbor. Odagiri immediately steps up to help the beautiful but seemingly timid Yuko while she struggles with moving boxes. Despite her stunning looks and constant apologies for even minor mishaps—making him feel something is off about this reserved woman—the dynamic shifts dramatically when a downpour catches her outside.
Forced to seek shelter at Odagiri's apartment because she lost her keys waiting for her husband’s return. In a moment of pure vulnerability and undeniable allure right before his eyes, Yuko strips off her soaking wet bra. Her large breasts are saturated and glistening beneath the fabric, causing an immediate erection in Odagiri. Seeing his reaction, Yuko doesn't hesitate; she accepts blame for the distraction and insists on thanking him by letting him fuck her!
This initial encounter sparks a relentless series of intimate moments. She thanks him again each morning after he goes to work, plunging Odagiri into a delightful state of sleep deprivation. Though he desperately tries to put boundaries around this escalating affair, he simply cannot resist the intoxicating charm of his seductive neighbor, Yuko Ono.
