Office lady Marina Fujimoto, having just decided to retire, was at the peak of happiness when suddenly plunged into a nightmare. Her ex-boyfriend corners her, demanding "one last time before you quit," and slowly torments her body before creampieing her. Watching the entire scene, her boss becomes aroused and devises a plan to capture Marina himself. She is kidnapped on a daytime street, dragged into a private home's yard, and subjected to forced blowjob and facial. The next day, when she tries to report the incident to her superior, he treats her like his personal property, humiliating and using her as a sex slave.
