A yakuza boss receives an irresistibly cute newlywed as a substitute housekeeper after his underling causes trouble. Despite promising not to touch her, he drugs her with aphrodisiacs, brands her with a lewd crest, makes her squirt, and trains her in increasingly perverse sex while forcing her to betray her husband. Soon the once-demure wife wears a vacant orgasm face, screams through climax, obeys every order, and even begs for forbidden sex and an affair pregnancy—the full descent into his convenient living sex toy.
