My slave is patiently waiting for me in a leather rest sack. I tie his cock up. I then proceed to sit on his face, smothering him with my ass. He is unable to breath. He struggles with me not moving, just smothering him with my ass. I get up and he grasps for air. He is so grateful for me, thanking his Mistress, to allow him to breath in my ass. I grind his face making breathing even more difficult. I torment his bound hard cock. I sit on his chest and rub my feet all over his face. He worships my feet licking in between every toe.
