You become a big, fat, hulking pig. Lusting and drooling for pleasure like the fat hog that you are. You are a porker. Your body transforms, making you bigger, fatter, with huge chins and a big muscular body to go with it.  Nipples, cock, and balls growing bigger, making you completely into a pig man. A squealing, oinking, slobbering, masturbating fat-muscled hog beast.
