Je bent niets dan wc-papier

You are nothing but a disgusting piece of toilet paper! You were born and put on this planet specifically to clean me up, to lick my ass and pussy clean and to eat my farts! If you are good enough and cleaning me up and I'll be pleased with your behavior, I might even allow you to go from being a simple piece of toilet paper to being my actual toilet! You want to open that stupid mouth of yours while I squat on you and push, don't you, slave? Well, let's see how impressive you can be, sh*thead!
