Held captive as collateral for her father's debt, a woman is humiliated by strangers and used for their pleasure day and night, awakening masochistic desires she never knew she had. Her only companion is a doll her father gave her as a child. Still waiting for her missing father to return, she is subjected to one semen-soaked training session after another. Guilt clashes with mounting pleasure as she is gradually broken into a sex slave: “Tell me… is something wrong with me? I don't even understand myself anymore.”
