Female investigator "Sui" decides to retire from spy work after getting married. However, her boss won't let her, and she loses consciousness from the nerve anesthesia administered to her. "I'll train you once more." When she wakes up, she is tied up and her breasts and private parts are being kneaded and manipulated. Her head is grabbed and she is forced to do a shaking deep throat. Her throat is dug and she convulses. A huge cock is thrust into her pussy, which is visible through her black rubber suit. There is no point in refusing. A humiliating M-shaped spread-legged piston thrusts directly into her uterus. "Stop it!!" She squirts multiple times as her clit and vagina are stimulated at the same time. She becomes a completely submissive human toilet. She serves herself with a deep throat. She happily sucks three cocks at the same time. She pees all her bodily fluids and screams and cums for a cock. Did you think you could go back to being a normal woman? Fall until you break.
