A company that strictly controls employees' daily lives by enforcing compulsory semen collection. Among them, employee Misuzu Kawanami diligently collects male workers' semen, regarded as mere "work" and part of "education." Though it should never be personal enjoyment, this practice is accepted as reality. The company's creed is "female supremacy, male subservience," establishing a bizarre system where older men are treated as M men and their semen extracted for "educational purposes." This environment reveals the true nature of authentic sadistic women, exposing how workplace relationships and power structures become increasingly distorted.
