I've bound the slave completely with several ropes and just carelessly sit on his face! I mercilessly smother him under my sexy ass while I'm taking care of my manicure - mostly ignoring his whining, struggling and shaking! The longer I keep sitting on his face, the harder it gets for him and the more panic he gets. I between I sit on his head turned sideways for a short time - and "accidentally" sit on his artery for a while ;-) Then the facesitting continues! I love how he's completely helpless under my ass and at my mercy!
