The plain and gloomy accounting clerk, Kana Amamiya, is actually a hardcore sex monster who can't be satisfied even with masturbating eight times a week. When she exposes employee Kita's embezzlement, she demands that he "violently **** her" as a condition for keeping him quiet. With her weakness exposed, Kita is molded into a sadistic cock slave to fulfill her masochistic desires, ****** to endure days of unprotected sex, verbal abuse, and oil play. Her demands gradually escalate, until she even tames the company president, leading to a threesome in the office… She is drenched in semen from two men, reaching climax after climax. On the surface, she pretends to be a serious office lady, but beneath the surface lies the true nature of her simmering desires.
