Extreme Facesitting For My Human Bar Stool

Now the slaves indeed going to suffer - Ill use him as my human barstool while reading and drinking a cup of tea at the bar! I order him to sit down and put his head back - then just step on his gams and sit down on his face with my full weight. Its truly hard for him to take - especially with the lack of oxygen hes getting - and the fear of my weight violating his neck if his muscles cant stabilize his head anymore! I sit down on his face and smother him under my ass again and again - and each time it gets harder for the slave. After a while I grab a rope and bind his head to my ass :-D Later I show some mercy and grant him a little rest - by pushing him to the ground, where the facesitting continues, before I drag him back up again and we continue in the barstool position!
