At first glance, Tsukasa Aoi seemed to have everything going for her - a loving husband, a life of luxury, and a successful career. However, when she received news of her husband's passing, her world came crashing down around her. As if that weren't enough, she discovered he had left behind a mountain of debts.

Despite her initial resistance, she was eventually worn down by the relentless demands and became nothing more than a sex slave, unable to survive without being used by men.
