Disgusting slave training

My slave will suffer extreme humiliation today! I like it when it becomes disgusting for him. I can laugh at the loser, which makes me very happy. First of all my slave will take care of my dirty boots. I want them clean and the slave will make that happen by licking them. Then I spit in his face and mouth. But I don't just spit some saliva, today I also spit chewed banana into his mouth and face! I don't want the slave to be dirty though, so I allow him a shower - I piss in his face!
