Yuuka is sent away from her husband on a three-day business trip to secure a deal that could determine her company's future. She was chosen because President Yoshimura, the client, is notorious for his arrogance and appetite for women, and her company hopes its most beautiful employee can win him over. Once the entertainment begins, her boss Sato is quickly drunk into submission, leaving Yuuka alone to face relentless sexual harassment. Her mind rejects Yoshimura's caresses, but her body is forced into orgasm again and again.
