For a second you can't see anything, but then you see yourself in a mirror.
Your whole body was studded with black spots and the rest of your skin seems to be white. Your legs end in hooves and two horns are on your head.
But this isn't the change who worried you the most. Your whole body has now a very femininbe hourglass shape and your black hair reachs down to your hips. Two breasts has grown on your chest and seem to be a D or an E cup-size. But the oddest change on you is the big pink udder which is now on your belly and looks like it is full of milk.
"I'm very thirsty.", says the witch,"But you can't run around naked!"
With a snapping of her finger a maid uniform appears on your body, complete with holes for your udder and your new cowtail. You try to run away, but you can't move.
"Don't try to escape! You will stay here as my personal milking maid!", laughs the witch.
