The witch snickers, watching you. "I was right about you after all. You had the ability to love, to reason, to make so much more of yourself as a human. But you are lazy, cowardly, a fool. For that you deserve the form of a swine, and that is what you shall be. But not a male swine, since that might be too much work for you to thrust during mating... seeing how lazy you are, I will make you a female swine, and a barren one so that no piglets will ever have to suffer at your laziness. You will have no purpose, no reason, no excuse for living - and you will be too dumb to realize it... You could have been so much more - with greater risk and effort, there is greater reward. Now you will never know the levels of joy and contentment that you have given up because of your own sloth."
You watch in horror as you become pudgy and your cock starts shrinking!!!
