Suddenly your fat dad bursts into the bathroom, locking the door behind him without turning around. You try to call out to him for help, but all that comes out is a loud howl releasing a big gust of breath reeking of shit. He turns around, his eyes widen, terrified of the creature that sit before him. You watch the subtle movements of his face as he inhales the shit-infused air. His eyes suddenly glaze over and he removes his pants, exposing his bare ass and cock, that you could see slowly standing on end. He grabs your toilet seat mouth and holds in open so he can set his big ass on your face. He starts pushing, forcing a giant hard log of shit into your mouth. But this time you can't help but wolf it down, some how completely in love with the turd, feeling it sneer against the wall of your throat on the way down. You start tasting something else too, something new, fur, hanging down into the bowl from his fat ass. Your dad is slowly being engulfed by thick brown fur as he releases more and more delectable shit into your gullet. He keeps changing slowly until your dad becomes an obese werewolf. He hops off your face and turns to face you, brandishing his large bright red cock in his large, hairy, clawed werewolf paws. He starts jacking of into your bowl, allowing you to lap up his delicious cum. He finishes and let's out a loud howl of satisfaction and you follow in suit, both having completely forgotten your once human lives.
