This device is a mix between a cock ring and basic chastity device.

The way it works is the leather strap secures around the cock and balls just like a cock ring by means of a buckle. Then the lock is attached so the buckle can not be undone. The penis goes through the steel ring just like in the gates of hell and is attached by 2 small leather straps. Cock rings help keep erections and can make them more intense. This neat device forces the wearer to keep it on.
