I bound the slave's hands to the bed's corners - making sure he's unable to move and completely helpless. Then I slam my ass on his face and smother him under my sexy ass. With his hands tied securely there isn't anything he can do but moaning. In between I rub my dirty stinky socks though his face as well - then continue to smother him. Later I also take off my socks and stuff them on his nose ... I wonder what's better - sniffing the stinky socks or getting no air under my ass at all?! :-D Let's see how long he can handle it!
