inventerius: This is my one bar prison. A dildo on a metal pole that can be extended upwards by a large screw. By placing the girl on the dildo and than extending it she is forced on her toes. There is a certain point of extension beyond which the girl can no longer step off the pole. Hence the name one bar prison. It is a very fun tool to hold her in place and has the added benefit of strengthening her calf muscles. -- source link
