Konan is a new employee of the company, and her boyfriend also works here. Konan comes from a wealthy family, so she is always protected and shielded from the dark sides of society. This time, she is assigned to a business trip with her department manager, Takeuchi. Konan strongly dislikes her boss, as he constantly sexually harasses and molests her. After finishing work, everyone goes out for drinks, and Takeuchi keeps pouring alcohol for Konan, causing her to become drunk and pass out. Seizing the opportunity, Takeuchi takes her to a hotel and proceeds to record a pornographic video of her. When she wakes up, she wants to escape, but he threatens to upload the video online, forcing her to comply. Due to her lack of sexual experience and skills compared to Takeuchi, her boyfriend cannot satisfy her like he does, so she quickly succumbs to his advances. She lets him have sex with her repeatedly, records videos of herself masturbating and having sex with him. Even after she finds out that he has sent those videos to her boyfriend, she is not angry and continues to engage in sexual activities with him...
