The butler has been entrusted with the mission of transforming his mistress's beloved daughter into a first-class dominatrix. To achieve this, he purchases new male masochist slaves from the market each time, presenting them with the instruction: "Please learn how to serve for the young lady's sake." The young lady learns various ways to use them—as pampered pets, licking dogs, foot mats, human furniture, riding horses, sandbags for practicing punches and kicks, whipping dummies to test new whips, or partial usage for anal and penis torment—gradually discovering her own preferences. Throughout this process, the male masochist slaves must maintain an attitude of enduring all torment without resistance. If the young lady finds them unsatisfactory, they face disposal—death—leaving them with no choice but to endure desperately.
