Scott saw as a long orange and white cat tail as it grew through out of his diaper.The rest of the group where too busy laughing to notice his new tail.
As he continued to watch, his hand and feet turned into orange and white cat paws. His body started to to be covered with orange and white fur and his face got pushed into a feline muzzle.
Once he was fully a cat fur Scott began hearing voices. "Wet yourself...", he looked around but no one other than his old laughing buddies were there. "Wet yourself...", he heard again. He could not resist he needed to wet himself more. He gabbed the beer and it turned into apple juice. He drank all of it and filled his bladder and the urine magically spread all across his diaper making it fully wet and yellow. Normally a baby fur diaper would self-clean but for some reason it did not.
Scott then realized he should share his gift with his pals.
