Kurt's skin before taking on a decidedly pink hue, much pinker than human skin. All his body hair falls out as he pumps his dick harder. His feet harden and turn pink, fingers shriveling into trotters. The one hand you can see thickens and grows together into a trotter/hand hybrid with three finger. His nose turns up and his nostrils flare, growing larger. His mouth becomes pink and rubbery pushing out into a snout with small tusks growing out of his larger, squarer teeth. He oinks loudly as his eyes become black, beady, and move to the sides of his head. His ears become huge and leathery, moving slightly to the higher on his head.
The fat comes next, his stomach swelling out into a beer gut that hangs over the waist of the briefs. His thighs become almost cylindrical and his arms become beefy and huge. His head becomes larger and his cheeks get flabby. He squeals like a pig as his waist and midsection put on pounds as well, causing the brief to strain tight against his hips and ass as a curly pink tail pokes out the back. He adds a foot and a half to his height as well a more fat before his engorged dick, tenting the briefs, finally releases it's load and he squeals loudly.
He appears to be done now, this huge anthro pig that used to be your roommate. He snorts and sniffs at the air before trotting out of the room. You hear a crash that brings you out of your shock and you get out of the closet to investigate.
Kurt (or the pig that used to be Kurt) has pulled the fridge on its side and is pulling food out, cramming as much as he can into his snout and squealing all the way. You yell at him stop but he just looks up at you, snorts, and continues digging in.
You can't believe you did this to your roommate. Sure, he was an asshole, but that didn't give you any right to turn him into some sort of fat, pig-hybrid freak. You watch pitifully as your roommate oinks and shoves himself full.
