Chika, the wife of a company president, spends her days servicing her husband's sexual desires at work. She is forced to give him a blowjob so that the other employees don't know, and is teased with a remote control vibrator. One day, her old lover, Mori, joins the company. The two of them, burning with passion as they remember the past, have passionate sex in the office. Then, a colleague who heard Mori's story joins in, and the three of them get into a wild frenzy.
