Strap-on Training for My Anal Slave

I prepare my slave for a very special lesson and make it unmistakably clear that I am claiming his ass now. First, I use my fingers and a glass dildo to slowly stretch him for use before I penetrate his asshole with my strap-on. I make it clear that in my dungeon, his ass must be deeply clean and ready for my hard cock at all times so I can use it as I please. While he works under my thrusts and feels my training inside him, I let him feel my dominance and mock his inability. I switch to doggy style to work him even deeper and demand he spreads his legs so he perceives every movement of my cock inside him. He endures the training just to be close to me while I use his defenseless body as my personal sex toy to live out my sadistic nature. Clip language is English
