Yvette uses her slave as her seat, while playing with her smart-phone.
First she sits on his body but soon she moves on his throat and face.
Seeking the most comfortable position on him, she gets a little angry because his struggeling for air and shows him, how she could easy hurt him with her spikey heels in his throat....
so he gets a little more quiet.. for the moment....
but under her fleshy ass is no air....
what's about full weight throatcrushing for punishment?
