I love strong slaves I can use as my floor for my various exercise routines. I prefer them to be silent, and not move a muscle so they don't break my concentration. First I use my floor to lift myself into the splits on his back, supporting my entire body weight on my hands only.... He cries out for mercy THREE times before I release my grip. How else am I to train him to hold his breath? I balance with one leg behind me over my head, he is completely useless. Well, he can support my weight, but that is all...So I kick him in the balls- a few times, before dismissing him. I continue using my stoic slave to test my leg strength. I permit him to massage my pussy with his tongue through my thin panties...of course, I proceed by gripping his head in a tight scissorhold, cutting off his air supply. He begs for mercy, I crush his throat again, .....ahhh the continuous rigorous training. I' m not satisfied with his performance so I kick him in the balls. So he gets a little reward.
