My potty was born just to feed on my faeces. He is already my permanent human toilet, and eating my shit is certainly what he can do best. Filling his open mouth with my shit is the greatest reward he deserves. When I crouch over his open mouth, he has to keep up with swallowing, he has to eat it all. He wont miss a thing, all the bits that fall off I put back in his mouth because nothing can go to waste. Training makes perfect.
