First lock your cock up, then fill up your urethra!
This urethral chastity cage first locks your cock in stainless steel. Once it's firmly on, you slide the urethral tube through the port on the front of the chastity cage. The stainless steel tip will push its way deep into you until the stainless steel base slides into place. You can then use the included hex wrench to lock urethral tube in. Pissing through the silicone tube will help keep things clean while you're locked in the cage. It also makes the cage more secure.
Of course, this stainless steel chastity cage is fully functional and secure whether or not you use the urethral insert.
