Mistress Enola wanted to humiliate as well as inflict pain on this guy. That is what she ended up doing and she had a great time dominating the guy. He was shocked at what she did to him and he wished he had never even met her. She spat on his face and as if that was not enough, she went ahead to trample the shit out of him and slapping him.
This slave needed to be shown who was the boss in that house as he did not seem to understand that. So the mistress gagged him using her bare feet and when she was done, she went ahead to spit into his mouth which she had forced him to open. It was humiliating and he wished he had been beaten or something else done to him but not to be humiliated with saliva.
