By day, three sisters live as a corporate CEO and her office ladies, but by night they transform completely into dominant mistresses. Roaming the streets, they capture their chosen male masochists, train them according to their desires, and lock them away in cages as pets for their pleasure. Advertising high-paying job openings, they lure numerous M men for interviews—those selected become subjects of intense SM play after dark. Though they operate under the name of a company, they face no financial struggles thanks to their parents' inheritance. Their recruitment of male submissives is more than just a pastime—it's an integral part of their daily lives. A sinister and pleasurable world unfolds as the sisters' desires and lust for domination intertwine.
