MetalBondage - Nina Grace on the One Bar Fucking Machine bondage

What if a One Bar Prison could move up and down? I just had to try it! Combining the One Bar Prison with a Fucking Machine makes a very fun challenge for new girl Nina Grace. She is standing in extreme Pleaser Domina heels, so she cant lift herself up, she is already on her toes. The dildo can move freely inside her, up and down, but it is still holding Nina in place. This turned out to be a rather difficult situation for her, as she got more and more aroused, but she still needed to focus on standing straight. Dont try this at home!
