You want to be denied long-term. You want to put complete control of your cock in the hands of a capable, superior Mistress. That must mean you want Mistress to lock you in a chastity device, right? Wrong. Cages are only for the weakest and most cowardly of submissives, the ones who can’t be trusted. And if I can’t trust you with your own pleasure, then how could I possibly trust you to serve me competently? If you want to be my boy, then you should expect to live a no cum, no cage life.
