Mimi Saotome works in the administrative department of a lingerie manufacturer, where her devoted nature and stunning beauty constantly draw attention from male employees. However, her father has accumulated massive debt, making her a target for men who begin setting up vicious traps to exploit her. She suffers sexual harassment from senior coworkers, forced into giving blowjobs and having them cum in her mouth. The company president then coerces her into sex by offering to cover her father's debts. Gradually, Mimi's mind breaks down as she is reduced to a complete sex slave within the workplace, descending into a cruel tale of domination and degradation.
