BON4M large stainless steel chastity cage

Secure and nicely designed package for the longer penis.
Select the hinged version if you wish for rings that can be opened and the solid version for closed rings.
Hinged will offer you more security and generally a better fit, while solid is less easy to put on but on the other hand causes less pinching.
Once the discreet package is delivered you'll notice a large variety of ring sizes to choose from. This is crucial as only a good fitting ring can offer you security and thus quality time. Chastity play can be such a pleasure, but only with a well functioning device.
Take a look at our friendly instruction movie to see how it all works. Once caged you will be controlled and one way or another forced into submission.
Get aroused by the teasing and orgasm denial yet stay focused and devoted to your key holder.
This BON4M can be worn 24/7 under all circumstances. The less experienced we advise to extend the days of wearing such a device slowly. Male chastity is growing rapidly and to many it's a dream come true.
There is by the way something that applies to most of the BON4M wearers; being locked and controlled for as long as their keyholder wants to!
