The cage Anna is locked in fits her just perfectly. Any smaller and she wouldn’t fit; any bigger and she would be comfortable. She has the freedom to move around, but no position is comfortable for long.
Thirst becomes an issue quickly. He can solve that if Anna is willing to drink what he offers. When she finishes he brings her out of her cage. Her freedom is short lived as he chains her up between the columns of the barn.
A chariot is strapped to her. The bar between her legs is not only affixed to her waist belt, but it has a dildo that slips into her cunt. As he rides her around his property she gets fucked by cold hard metal.
