My father died suddenly in an accident. A few months later, I was relaxing at home when my mother, who was supposed to be living in the countryside, unexpectedly showed up and announced she would be moving in with me. I didn't ask for a reason—I was living alone anyway—so we began living together. Some time later, I returned home during a break from work and found my mother in a shocking state: tied up, being sexually tormented by a man, drooling and moaning helplessly. I stood frozen, unable to move, just watching the scene unfold. That night, I left work early and rushed back home. The man was gone. I confronted my mother about what I had seen and learned the truth. Because of my father's fatal accident, my mother had taken out loans from dangerous people to cover the compensation costs. Unable to repay the debt, she had been forced into prostitution, her body exploited by loan sharks. As she hung her head and whispered, "I'm a failure as a mother," I pulled her into an embrace and said, "You're still my mother," and we both wept. Then, as if making a silent decision, she looked into my eyes and gently reached toward my crotch. She was offering her body to me—paying me back in the only way she thought she could.
