Jeu d’humiliation de chasteté : récupérer ta clé de chasteté de préservatifs sur des godes avec ta bouche

Me & my chastity sub played a bit of a humiliation game I've thought up. I put 5 chastity cage keys in a condom on 5 of my dildos and Rod has to retrieve each of the keys from off the dildos with his mouth while blindfolded to unlock his chastity cage. One is on the floor, one is on my fuck machine, I hold one for him and two are on the wall. I have him chained by the balls and his hands shackled behind his back while I sit and watch and direct. The catch is that none of the keys unlock his chastity cage like he thinks, im not that stupid, letting him get his cage off already! The actual chastity cage key was never in the condoms, I've padlocked it to him so he's wearing the key the whole time.
