There are nine parts in this complex, all-metal butt plug with a metal ‘clanger’ inside the hollow shell. Every movement causes the Rattler’s inner clanger to knock, roll and rattle against the inside wall of the plug. This sends vibrations through the wearer! It’s a little like belling a cat, because you’ll have a pretty good idea where the boy is when he moves around with the Rattler inside his tight ass. Wiggling the base can cause quite a reaction when he’s unable to pull away. Or plug the boy, and take him out for the night. You’ll enjoy watching everyone’s reaction!
