Minami Aizawa finds her peaceful life shattered when her estranged younger brother reappears after five years, revealing he is drowning in a massive 100 million yen debt to dangerous loan sharks. Despite her recent engagement and plans for a happy future, Minami cannot abandon her only living relative. When they approach the syndicate boss to plead for more time, the ruthless criminal spots an opportunity to exploit her beauty. He proposes a dark ultimatum: Minami must become his personal sex slave for ten days to clear her brother’s debt entirely. With no other options available to save her sibling, she reluctantly accepts the degrading deal, trading her autonomy for his freedom.
During these ten days of captivity, Minami is forced to abandon her dignity and her former life. Clad only in suggestive lingerie, she is required to be available at the boss's beck and call, performing oral sex and enduring intense intercourse whenever he demands, often in the presence of his intimidating subordinates. The environment is one of total submission, where she is treated as a possession, constantly covered in cum and forced to shed her inhibitions. The psychological toll of the situation quickly shifts, as the shame of her circumstances begins to transform into a perverse, overwhelming physical pleasure that she finds impossible to resist.
As the ten-day period reaches its conclusion, the power dynamic has shifted entirely. Minami’s initial desperation has evolved into an insatiable craving for her captor's touch, causing her to abandon all thoughts of her fiancé and her brother’s original plight. She finds herself so addicted to the intense sexual gratification provided by the syndicate boss that she refuses to leave, choosing to remain his captive to continue their illicit affair. This gripping JAV drama explores the dark descent of a woman completely consumed by her newfound, primal desires.
