A rejected former coworker becomes obsessed with Natsuki, a beautiful busty college student, and is fired after she calls his behavior stalking. He continues watching her commute, then breaks in and attacks when she rejects him again. Trapped and terrified, she is raped, restrained, and held captive while being subjected to humiliation involving feeding, bodily functions, wax, bondage, toys, forced deep-throat, and repeated creampies. The violent, tireless attacker keeps driving her into screaming convulsions until she is reduced to a sex slave, then urinates on her face, leaving lasting terror and trauma.
