Asuka Momose plays a devilish expert mistress teaching her own dominatrix manual and an anal-training method that hooks even the sleaziest men. What begins as a casual affair turns into total control of his body and mind. She reshapes him through relentless anal play until he can orgasm from his ass, mixing creampie sex, piss play, and strap-on fucking that makes him cum repeatedly. Day after day she works his ass and forces one orgasm after another, assuring him she will never leave. Soon he is hopelessly addicted to ejaculating, filling her with creampies, and cumming from anal stimulation.
