The protagonist is an employee of Mind Control Co., spending his days using the company's brainwashing devices—disguised as door-to-door sales—to unleash people's sexual desires. One day, he brings home a woman who has been brainwashed by one of these devices and makes her his personal maid, indulging in depraved acts with her. Under hypnosis, the maid becomes extremely sensitive, experiencing intense pleasure repeatedly while endlessly sucking her master's cock—this is the highlight. The overwhelmingly pleasurable scenes are a major attraction, delivering strong temptation to viewers.
