«The device is called "One Bar Prison"... condition for being inescapable is that the girl has to wear tall heels to prevent her from lifting herself up: https://www.metalbondage.com/category/one-bar-prison-custom-design/»

«There is one upper dildo bar that slides up and down in the lower tube bar.
The rigger just has to lift the upper bar into her pussy then lock it in that position inside her.
The key she's given at 1:38 is for unlocking the upper bar, she thinks she's soon free, but the screw is too far low, she can't reach it, she's definitely stuck.»
