Teacher Nao lives a life as a sex slave... completely dominated by men who repeatedly toy with her beautiful, innocent body. As she approaches the limits of her psyche, her students forcibly shave her armpit hair during class and gang rape her. Awakening to sexual pleasure, Nao experiences even greater humiliation in front of her students, forced into relentless bodily servitude. Her body can no longer escape... she continues her descent into becoming a complete slave.
