A workplace stalker targets K, a beautiful, high-powered office worker, and escalates his abuse over seven days: filming under her tight skirt, spying in the changing room and restroom, then groping her on the train. He breaks into her locker and ejaculates on her skirt, watching the fresh, warm semen run down her thigh. The next day he slips a semen-smeared photo into her desk drawer to savor her reaction, then secretly films her at home having phone sex with her boyfriend. On the final day, he takes her away while she is barely conscious and injects her with an aphrodisiac, then forces a large amount of semen into her vagina and mouth. This ejaculation log records his countdown to turning a woman from his workplace into a cum receptacle.
