This part begins with relaxed sitting on his face, Jill sits reverse on his face, her soft and fleshy ass flows complete over his face, no air! But he is so completely down, he even don't struggle for air... but he cannot be for long without and begins to move?
So Jill decide, it's time for more punishment, she jumps with her knees on his chest and bounces there, sqeezes his throat with her hands and her weight, takes the air-supply with hands over mouth (HOM) and... sitting again, this time foreward, on his face, sealing the nose and mouth propely by pussy-press.
Then the harsh treatement goes on, more knee-jumps and stompers combined with HOM and windpipe-squeeze.
