You decise to try on the frumpy Ugly Sister dress.
Its much too big and hangs loosely off youre body.
Laughing as you look in the mirror, you put on the ginger bob wig which accompanies the costume.
Suddenly you realise that the hair has become your own. You tug at the wig but it hurts, its actually your own hair now.
looking confused you check it in the mirrow and see that your nose has become bent and hooked and you watch in amazement as a large mole appears on your cheek.
"What the hell!" you stammer as one of your front teeth becomes dislodged and falls out.
You look on in horror as you realise the costume is not as loose as it first was.
You feel a swelling in your rear as your buttocks expand giving you a very large feminine butt.
Lifting the dress up to the waist you watch as your thighs become pasty and flabby and your penis begins to shrink.
"NOOOOO!!!!" you cry as your now tiny penis is sucked inside a very hairy vagina, leaving you with a plump pussy between your chubby legs.
you feel a sudden pressure in your abdomen, as if you have to burp.
In an instant your tummy begins to swell up into a large belly.
totally dumbstruck you look at your body in the mirror, an overweight woman with tree-trunk legs, a large chubby belly and ugly face stares back.
You look down your dress as you feel the same pressure builing up on your chest.
Watching with a mixture of shock and amazement you see your breasts begin to swell, first into large attractive boobs, then sagging into middle ages tits, drooping and resting on your now considerable stomach.
Stunned, you pat your massive female behind and then cup your huge droopy breasts. Its now your body.
The costume fits perfectly.
