After seven years of raising her younger brother alone, Kana Momonogi finds her life turned upside down when his gambling addiction lands him in deep trouble with a ruthless criminal syndicate. Desperate to protect him from the mob boss he robbed, Kana agrees to a dangerous bargain to clear his mounting debts. The leader, instantly captivated by her, demands that she serve as his personal woman for ten days. Forced into a life of total submission, Kana is stripped of her autonomy and must remain either nude or in revealing lingerie, ready to satisfy the boss’s every whim at a moment's notice, even in front of his intimidating subordinates.
As the days progress, the power dynamic shifts in unexpected ways. While she initially entered this arrangement out of pure sacrifice, the intense physical encounters with the boss’s massive cock awaken a deep, insatiable hunger within her. She realizes that the overwhelming pleasure he provides far exceeds anything she has experienced in her past relationships. The constant demand for her body, combined with the raw, dominant nature of her captor, leaves her physically addicted to his touch. Her body begins to crave the intense sensations he forces upon her, creating a complex bond that blurs the lines between fear and erotic obsession.
When the ten-day period finally concludes, the debt is settled and Kana is technically free to return to her previous life. However, the experience has fundamentally changed her desires. Instead of fleeing the criminal underworld, she finds herself unable to walk away from the man who conquered her. The story concludes with a shocking realization: Kana no longer wants her old life, choosing instead to remain under the control of the boss, forever addicted to his sexual dominance and the profound satisfaction she finds in his presence.
