Kojima, the section chief who lost his job due to restructuring and was finally hired, is being oppressed every day by the female president, Yumi. One day, when he was ordered to work overtime and remained at the company, perhaps letting his guard down as there was no one there, he witnessed an affair scene where a stranger was invited to the company and succeeded in secretly filming it. At a later date he will rape it as a joke. Before long, she becomes Kojima's sex slave.
