Rei Mizuna takes on the challenge of anal sex using real iron restraints in order to bring her M-ness to a deeper level. While enduring the pain of iron restraint that completely ignores the structure of the human body, Ji Po, enema, and iron toys attack the anus and rectum one after another. A must-see for restraint maniacs, anal maniacs, and Mizuna fans who have anal violated by the medieval torture device "Pear of Agony"!
