Slave Struggles Under My Jeans Ass

Ive pushed the slave on the couch and drop my ass on his chest - and he already starts whining! But of course I didnt plan to just sit on his chest. I want to sit down on his face and smother him! As my ass prevents him from breathing he starts struggling even more - but I wont get up until he stops moving - so its up to him - stop moving or pass out :-D Lets see how long he can endure this game!
