Fat exploded out of nowhere. Bulb! Her ass bugled so much her pants exploded at the seams. She grew a triple chin. Her udder was the size of a beach ball and her waist was enormous. Her stomach bubbled. And somehow she expelled more gas." WoBRAPPP! That was a terriPRBLLTT! Desicion."
She looked around 600 pounds and was now waddling away. " let's go to thiBRAPPPPRBLLT! WhoH that was ripe."
A small mutt walked by it paused and smelled the fart belch combo. Shaking its head it started to bloat up. Gas leaked form its now monster ass eventually the dog weighed 300 pounds and was now half cow.
" Oh my god! We can make more people like us by farts and burps. Let's eat out, al there spread our fumes as we walk and get lunch."
" sounds like a plan." The girls waddled away spreading their fuse as they went soon the entire town was ethier a fat anthro cow with terrible gas or an anthro pig with vide versa.
