Their purpose apparently fulfilled, the breasts fall away, rolling out from under your shirt and melting into a puddle that slithers away as it hits the ground. Of course, you still have to deal with that thing living in your belly... or maybe not, as the belly falls off too. However, unlike the breasts it doesn't simply melt, instead retaining its round shape. For a moment you wonder why, but then you see just what shape it's taken.
The chunk of latex that had covered your belly now lies on the ground before you, its elongated shape showing its true nature. Though still patterned like cow hide, there's no denying that this is an egg. Then again, it could be another elephant for all you care. It's not on you anymore, a fact you feel nothing but relief over. But wait... if the latex is leaving your body, why didn't the udder fall off? It should have left with the rest but it's still attached, its contents sloshing about as you move.
Maybe you need to take it off by hand? Worth a try. Reaching down, you pull your shirt up over the smooth latex of the udder... further... further... you must have the shirt up to your chest, so why is everything down there still so smooth? You take a look, and realize with horror that the breasts and egg left you a little parting gift. Your gut may be its regular size, but it's now completely smooth, covered in the same black and white latex cow hide as that egg. Your chest hasn't fared much better, though you aren't sure you can even call it that anymore. It no longer has any definition, not even a trace of a nipple. It's now just as smooth and just as cowesque as your gut.
You pull down your shirt - you've seen enough. You try to squeeze into your pants (a task you barely manage as you're forced to leave your udder sticking out the top and still can't even zip them up), and decide to get the heck out of there before whatever's in that egg gets out.
