My neighbor Hibiki, who moved in next door after my transfer, appeared to be a serious and modest married woman. But one day, I caught her digging out an adult video from my trash bag and masturbating right there on the spot. Neglected by her husband and suffering from sexual frustration, she harbored hidden desires directed toward me. She plays the innocent wife in front of her husband, yet reveals a lewd and daring side exclusively to me. Enchanted by her duality, I find myself irresistibly drawn into her true nature.
