Spitting Down On Him

I truss the slaves forearms with strong duct gauze on his back so he cant get away from me, then pull his head back and start spitting all over his face. I know how much he hates it - and I LOVE how he hates it :-D Its just so much fun looking down on him, moaning in disgust and humiliation! Ive got a lot of spit today and its running down his face - slowly covering it completely!
