Mike stared at the stableboy with fire in his eyes. If he could just get this saddle off him he'd grind this kid into dust. "Humiliate a centaur huh?" Mike grunts struggling against the saddle's magic.
"Yeah lets see how good this one works." The stableboy giggles, moving the brush over Mikes sleek equine coat. The sensation was very pleasant, like a gentle massage combined with some tingling warmth. Mike twisted around and watched in growing amazement as his coat turned a deep muddy brown, and muscles began to build. As the boy continued, his legs shortened. The kid paid special attention to his sexual equipment, and Mike found himself enormously erect. His penis, already that of a horse, dropped out as it swelled thicker, but shorter becoming a mottled pink and black shaft that felt heavy and pleasurable under him. His testicles seemed to contract and shrivel hanging down in their thick black sack. When his entire equine half was done, the stable boy stepped back looking him over grinning.
"Hmmmmm.. nice equipment...to bad they're useless now."
"What?" Mike yelled looking back.
"Yeah a Muletaur can't breed...it's sterile....
