Smothering And Choking The Slave

I order the slave to lie down on the floor and sit down on his chest - this way I can ideally throttle him with my palms! I press my mitts on his nose and mouth with all my power and make sure he cant breathe. I take the slaves mouth between my powerful legs shortly - but I dont really like that position. I switch back into sitting on his chest and smother him some more. I mix in some choking and enjoy feeling his bruised body struggling with the lack of air!
