Bondage and submission is part of my Slave training. I know my master loves making sure the rope he tied me up with is really tight against my skin so that if I move, I get rope burn. He told me to be a good submissive Whore and lay back. That is when he climbed on top of me and started riding my face. He spread her ass and I knew I was going to be doing some Prostate milking. I stuck my tongue out and started licking my master’s asshole. I could feel the rope starting to grind against my skin. The more I licked him the harder he rode my face, the more the rope started burning me. I could tell that my master was jacking off as he was getting prostate milking from my tongue. It had my cunt wet and dripping, wishing my master would just fuck me. But he kept riding my face and I licked him hard until I felt his balls tighten up and I knew he was going to bust a big nut. He turned around and started choking me as he sprayed my face with his cum. He called a good cum slut and left me there tied up in bondage to use me again when he is ready for more Prostate milking.
