This butt plug harness is made to lock in an inflatable butt plug so it can not be removed by the wearer. The harness incorporates 3 locking buckles and a fixed two inch steel cock ring for an extremely secure fit. The butt plug is designed to fit seamlessly into the harness with the rubber tube and bulb feeding out of it. It can even be used without the plug.

The harness fits most men with 29 to 40 inch waists.
