Mistress Sarah: I'll spit in his face and rub it with my feet.
He'll receive the ultimate humiliation: I'll spit in his face and rub my spit in his face with my feet. I'll sit on him and see how well I can aim my spit. He gets my spit in his mouth and in his face, and I can see how much he enjoys it: his painlessness and my spit. He especially enjoys the humiliation of me rubbing my spit in his face with my sexy soles, leaving him with a mixture of sexy spit and foot sweat from me...
