For a Hardcore Hard On, there's no better erection enhancer than The Triple Helix Cock Cage. Designed to fit around your cock and balls, this will harness your erection and keep you up as long as you please. Easily sized to fit your penis, it also features a quick release system to let you down when you're ready to call it quits - but not a second before! These three rings are able to be trimmed for a perfect fit and easily come apart when you are finished.
The rubber material works best with water based lubricant, so use lots of it and slip on the Cock Cage for a night of fun!
