Usually, before stuffing a slave with my poo, I guideline him to eat my beaver and my asshole, that I will be emotionally ready and relaxed. With enough good lighting, you can see a close-up - I fill the slaves mouth with shit and at the same time make him to drink my pee. All this comes out simultaneously and drops drip right down my shit and fall into the throat. In order not to feel discomfort and unpleasant odor, I make the slave to swallow quickly. He realizes that he is JUST a TOILET for me and I will use his mouth later again.
