I have my slave on the floor, and he wants to masturbate himself. Of course, it's not very interesting for him with out having some incentive. So I'm going to give him all the incentive he needs. As I stand over him and get him to open his mouth, he will have the luxury of enjoying my delicious shit. What a lucky slut to have the best of both worlds, being under my beautiful ass while wanking himself at the same time. With his mouth open he catches my delicious shit. It also covers his face, and he has to make sure he doesn't waste any as he puts it into his mouth. I leave him to enjoy his orgasm.. What a shit face wanker!!
