Helplessly Bound For Facesitting

I tied the slaves mitts to the beds corners - making sure hes incapable to budge and entirely helpless. Then I slam my ass on his face and smother him under my sexy ass. With his hands tied securely there isnt 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 whats better - sniffing the stinky socks or getting no air under my ass at all?! :-D Lets see how long he can handle it!
