An iron restraint device passed down from medieval Europe, completely restraining an M-girl and thoroughly torturing her anus. This time's sacrifice is 'Nanami Yua.' Starting the training in a shamefully naked and immobile state. Powerful slaps to the cheeks and breasts. A huge dick and various toys, along with a pear of anguish, are inserted into the anus one after another, culminating in an orgasm between pain and pleasure.
