Cheating Slave Throttled Under My Feet

Now Ill throttle this slave under my sexy feet. I press them hard on his mouth and nose - but he still manages to get a little bit of air through the side of his mouth - so Ill have to seal it with duct gauze! With his mouth taped shut and my feet throttling his nose, he undoubtedly cant breathe anymore. I go a little stiffer on him, by standing on his chest while I strangle him with the other foot as well, then sit down on his belly and press both feet hard on his nose! In inbetween I rip off the tape to see if he learned his lesson - but he still tries to cheat - so the tape goes straight back on!
