A married couple had been living a sexless life for two and a half years. One day, the husband left work early and returned home, only to hear a familiar male voice coming from the bedroom. Hesitantly entering, he discovered his wife passionately teasing the nipple of her subordinate, caught in the act of an affair. Overwhelmed by shock and anger, thoughts of divorce crossed his mind—yet he found himself aroused by his wife's seductive expression and appearance. From that moment, he began installing hidden cameras throughout their home, secretly recording his wife's nipple fetish affair. Each time he watched the footage, he became increasingly captivated by her, plunging into days filled with unprecedented desire and emotion.
