Fat Piggy Petunia

It's been weeks since the formerly brilliant grad student Bess disappeared. No one knows that Bess is a guinea pig in an experiment by her professor, an experiment that's gradually turned Bess into a fat, gluttonous, massively buxom bimbo cowgirl with big milky tits. But Bess' old roommate Petunia is determined to get to the bottom of this mystery and find out what happened to her old friend. Unfortunately for her, the professor has a new formula that she's been dying to test -- and before it's over Petunia will be undergoing a transformation of her own. This is a weight gain, bimbofication, pig transformation story that continues the tale of 'Fat Little Milk Cow Bess'.
