Smothered By My Powerful Bare Feet

I love to play violent strangling games with the slave - and I especially love to use my powerful feet to throttle him! I ordered him to lie down on the couch and then start to smother him. At first I sit on the couchs back rest and press my feet on his mouth and nose - then stand up on his chest, let my full weight sink into his chest and then press my other foot over his mouth and nose. I switch between these positions for a while - then sit down on his stomach to make it harder for him to breathe when I lift my feet to give him some rest - and then press both of my powerful feet on his face to shut off his breathing completely!
