Lock up your slave cock and balls so he is completely at your mercy!
Torment your man with tightness! Wrap one strap around his cock and balls, locking it at the adjustment point that he can just barely handle. Push his cock through the cage to ensure that his arousal does not lead to an erection. Then pull down on his balls and wrap his scrotum with the second strap, locking it to the cage as well! Once he is fully confined, enjoy having your way with him while he struggles to keep calm. If he starts to get hard, the metal rings will dig painfully into his sensitive flesh! Two D-rings at the end of the cage allow you to add weights, a leash, or a variety of other BDSM accessories.
Wipe clean after each use with mild soap and warm water.
