With seven days remaining, office worker Y goes about her job unaware that a stalker is escalating from panty glimpses and changing-room peeping to toilet spy cameras and train groping. He tests sleeping pills by exposing and fondling her nipples, hides a semen-smeared photo in her desk, marks her skirt with cum, and secretly films her having phone sex with her boyfriend. On the final day, he takes the barely conscious woman away, injects an aphrodisiac, and assaults her mouth and vagina, filling both with semen. The video records his week-long countdown to reducing the tall, big-assed office worker to a receptacle for his cum.
