Kana, entrusted with a crucial business negotiation that could determine her company's future, is forced to go on a three-day business trip, leaving her husband behind. The reason she was chosen for this important deal is because the client's president, Mr. Ozawa, is known as a womanizer and an arrogant man. The company's president specifically selected Kana, the most popular and beautiful employee, hoping her presence would ensure a successful agreement. However, once the hospitality begins, her superior, Sato, quickly backs down, leaving Kana exposed not just to entertainment, but to relentless sexual harassment. Kana outwardly complies with Ozawa's advances while internally resisting, but her body gradually responds to his touch, repeatedly driven to orgasm. This escalating intimacy profoundly impacts both Kana herself and the fate of the business deal.
