The MC Mansion series is crafted by director Kei Morikawa, known for his brainwashing drill films, and researcher Saki, renowned for her hypnosis projects, creating a unique and captivating world. In this installment, Yoshimura, the head of planning and development at MC Co., works as a mansion caretaker, secretly testing various hypnosis gadgets. When a woman discovers his activities, she confronts him—only for Yoshimura to use a hypnosis light to turn her into a sex slave. He then indulges in intense perverted acts, testing a new type of specialized masturbation sleeve that heightens her sensitivity and arousal, leading to deeper, more decadent pleasures. This work delivers an intensely immersive experience through its original concept and masterful execution.
