You begin to feel light-headed, for some reason your body feels heavy, it's hard to stand.
Your trembling legs give way and you fall flat on your butt. It hurts, but not quite as much as you expected.
"What's happening to me?" You wonder, struggling to get up.
Suddenly you feel a sharp pain in your butt. Your silky bloomers seem to be shrinking! You cry out in pain as the feeling speads to your stomach and chest.
After a few seconds of agony there is a loud RIP as your huge butt tears the bloomers to pieces and your thigh-high stockings are stretched to breaking point.
Your breasts pop out from the top of your dress and you can see that they are growing before your very eyes! Previously a B-cup, they're now a whopping D-cup and still growing.
You reach up to touch your face and find that it has become soft and squishy, it is getting harder to tell your neck from your chin.
Once you feel that the changes have stopped, you pull yourself into a standing position, with much difficulty. You wonder if these changes are temporary, or if will you be stuck as a fat princess forever.
