At a certain underwear manufacturer's general affairs department, Mimi, known for her dedicated personality and beauty, is the center of attention among male employees. However, her parents have a large amount of debt, which various men exploit by setting up despicable traps. Forced to perform fellatio due to harassment from senior colleagues, she is made to receive semen in her mouth. The president coerces her into sex under the guise of paying off her debt. Mimi is utterly degraded, turning into the company's sexual slave.
