"I want to become an unborn foal and start all over." Mike looked around expectantly, then frowned.
"Get real! I'm not a genie!" Brian laughed and shook his head. "We'll need a mare, dummy! Let's go back to the pasture."
Mike sighed and nodded, and let Brian ride him back. They took a shortcut through the woods, though Mike had some trouble in a few places because of his great size. They soon emerged at the back end of the pasture, and the huge back Shire mare that Mike had mounted first came trotting over. Brian grinned. "This is perfect! You are going to be your own father! How is that for freaky?"
"My own father?" Mike looked confused while Brian slid off his back. "If my semen is part of it, that would mean I'd have to be..." His eyes widened just as Brian pressed one hand against his side and the other on the mare's belly. There was a flicker, and then Brian was alone in the pasture with the mare. The stable boy ran his hand under the mare's belly and concentrated, then smiled to himself. It would be months before the just-fertilized egg was big enough for Mike to become aware, and a full year before he was reborn as a filly or colt. For all intents and purposes, Mike the human or centaur had ceased to exist. The big question now was if he would remember his past or just be a normal animal.
