Mistress Katherine Green toys with Her slave and his ability to breathe. She sits on his face and smothers him until he squirms and turns pink. She slaps his cock and balls to see him squirming even more. She stands up on him, trampling him, and bounces up and down on his rib cage and belly. The more he squirms in pain and discomfort the more She giggles and enjoys Herself and the more he entertains Her. She spits on him, slaps his genitals, tramples and stomps on him, and laughs in glee.
