Check out this buttplug harness, which is perfect for making sure that plug stays put – whether it’s metal, silicone or vinyl. Available with a locking or non-locking option. Metalbond prefers the locking version, because it means your prisoner is just going to have to suffer with that buttplug until you decide to take it out. Keep him locked in long enough and you might just get to watch his pants get dark with precum!
