A new girl today on MetalBondage.
Well, Nicole Vice is back, and she brought a new One Bar Prison friend for support! So you really need a screw that needs tools to open.
But for Mistress Kristin, we decided she should be bare feet, and stand on a little bar with her heels.
This time, we challenge her to spend some time on the One Bar Prison.
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.
Then the shaft is lengthened so that the subject has to stand on the balls of their feet.
There is a spreaderbar at the bottom end that can be clipped to a Metal baseplate.
The shaft is aluminium i think and it goes about 5 cm into the dildo.
