I have a new slave eager to please me, and as always I have some nice ways for him to be “useful” for my purposes! One of my favorite activities is spitting! Receiving my saliva should be considered a honor! So I start by spitting in his useless dirty mouth, and have him swallow the precious spit.
I start spitting in the palm of his hand, and have him lick and zip the precious saliva. I place him in a convenient position and let the spit drop straight in his dirty mouth
