Taking a morning dump!

Slowly, you feel her ass moving, and you finally get a small breath, before her ass settles, but instead of her asshole being on your nose, it's forcing your lips open. Right as you realize what's happening, a massive stream of diarrhea fills your mouth, sliding down your throat.

"Haha! How does that taste?" She says, as she laughs. You feel it filling your stomach slowly but surely. You hate the taste.

You then feel something more... Solid. "Open wider!" She says, before a large log of shit slides down your diarrhea-lubed throat.

It tastes like horrid hamburgers and beans.
