BON4Mplus High Quality 2 Cage Chastity Combo in Stainless Steel

NEW – You’ve done it; all men have. Secretly checked out the competition in locker rooms. You’re happy to see you fare well, perhaps bigger than average.

Don’t let it go to your head — either of them. Though you’re adequately equipped, you’re at your best observing to your Keyholder.

Our innovative 2018 two-cage package for average to large men (flaccid length: 2.6” – 5.2”) keeps you faithful, frustrated, and therefore obedient.

The two cages, with 7 cock and ball rings (CBRs) so you’ll be sure to find the one that keeps you secure for your Keyholder and avoids discomfort for you. The redesign CBRs swing 360° on a hinge, so placement is simple and painless.

To further ensure proper fit, we include three ring and sleeve spacing options. You and your Keyholder can enjoy the fitting process as a tease with the end a foregone conclusion: the ring closes the shaft passes through the ring and the cage. Click! The shackle of your custom BON4 lock shuts. Your proud toy now belongs to your Keyholder. How long will you be locked safely away? An hour? A week? A month? It’s up to your Keyholder, so be docile and obedient.

With the two cages, your Keyholder not only controls your degree of confinement, possibly allowing a partial erection, but also the size of your bulge. Hide it or emphasize it at your Keyholder’s whim.

BONUS – a silicone companion cage, useful for security checkpoints and a different visual appeal, is included for your convenience. Use uniquely numbered plastic steel locks instead of our metal padlock.
