It's my world now

You thought turning me into a girl would teach me a lesson? That was pretty stupid of you. Just as it was pretty stupid to leave your spellbook out where I could find it. It turns out that I'm twice the witch you ever were. Your former coven seems to think so, and they are much happier as the young hotties I turned them into than the dumpy middle aged housewives they used to be.  And they sure know how to show their appreciation. And rather than risk having you turn me back to my former male, unmagical self, I'm going to have you join them. Once our coven reaches thirteen members, I'll have enough power to transform the world into my sexual playground.
