My Mistress has both me and a male slave. Neither of us are allowed to masturbate or orgasm without permission, but She lets him cum way more than me. Usually She'll bring me to the edge and leave me there, but with him I guess She likes playing with his cum or something, so She lets him finish. Kind of unfair, I think, but I did submit to Her originally because I liked the idea of being treated this way. I'm enjoying that She's having fun with me, even if I don't always enjoy what she does, and that's better I think.
