Buster Lewis, the mechanic, shifted uncomfortably. Madame Illusia looked him over - he wasn't a bad-looking guy - in his late thirties, balding and a little heavy. He looked very nervous, and bowed his head slightly in respect as she approached.
"The town grease-monkey?" Madame Illusia grinned. "Perhaps you would be happy to become a grease-monkey for real? Able to use hands and feet as you work on cars? But no. You seem to have the proper fear and respect for my power. I like that. Let's see. Perhaps I can try my hand at your line of work. First, a tune-up."
With a wave of her hand, she stripped 20 years from Buster's age. He gasped as he became a lean 18 year-old with long hair and acne. "And a wash and wax." His acne cleared, hair styled itself, and clothing changed. Now Buster looked like something from a men's fashion magazine - a young movie star or pop singer. "And lastly, the one thing all of his customers want - lots of extra horsepower."
Buster gasped as his legs swelled out, tearing the new slacks apart. His ears beacme pointed and shifted higher on his head, and his handsome features became coarser and slightly pushed out. Muscles rippled over his chest and arms, and he grew much taller as his legs split and stretched out huge and powerful. His penis and testicles swelled out into the equipment of a stallion - a very large stallion.
When the changes stopped, Buster was a massive centaur with the human torso and head of a teenage bodybuilder, and the horse parts of a Clydesdale stallion. Even his face was very horsey looking now, but the pushed-out features and animal eyes made him exotic.
"So, what do you think of my modifications, Mister Mechanic?" Madame Illusia smirked as the transformed centaur looked himself over.
Buster grinned broadly, obviously veryhappy - until he tried to speak. A horse's whicker escaped his mouth - followed by the whinnies and snorts of an animal. The witch smiled. "Definately sounds like a request for more horsepower to me." She wavved her hand again.
The centaur's face pushed out more, mouth and nose thrusting out into a full muzzle. In moments, Buster had the full head of a Clydesdale, making him an equitar. Illusia looked him over. "How about now?"
This time, Buster simply nodded his head, horse eyes wide with fear.
"Very well." Illusia turned to the audience. "Your town grease monkey now has a stable job for the rest of his life!"
