“You make a very nice cushion slave” says Mistress, making her ass comfortable on the slave’s face. “Smell my juicy big ass smothering you, taking all your oxygen away. Slaves don’t need oxygen. you’re losers anyway. Learn to use your oxygen wisely, you never know when you are going to get any more.” Mistress leans forward to allow the slave one breath then sits right back down again. Every time she gets up she only allows him one breath. The slave starts to wriggle and thrash about, gasping desperately whenever Mistress allows him out from under her ass. He is getting red in the face from being buried under Mistress’s divine butt.
