Throttled By My Big Powerful Feet

I want to have some joy with the slave and order him to lie down - so I can sit above him and strangle him with my feet! My big nude feet cover his nose and mouth lightly and he cant breathe even a little. I attempt out a few different positions - like standing on his chest with one foot and throttling him with the other one, standing behind him and covering his face from chin to forehead with my big foot, sitting on his stomach and pressing my feet firmly on his face - all very comfy for me - and all of them leave the slave breathless under my feet!
