Len Yo Wong, an exchange student from Beijing, walked up to the stage with a broad smile. Of all the amazing things his Amercan friends at school had shown him, this was by far the best. How was this woman creating such realizstic illusions?
"What is your name, and where are you from?" Madame Illusia looked him over as he stepped up next to her.
"Len Wong. I is.. am.. exchange student from Beijing, China." He flushed a little, emberrased by his broken English. "I study saving of animals. Help stop extinct being."
"How perfect!" The witch grinned. "Tell me, my lovely young man, have you ever heard of the Asian wild ass, Equus hemionus?"
Len wrinkled his forehead. English was difficult to understand sometimes. "Yes. It be endangered. One I will help save."
Madame Illusia laughed. "Indeed you will! But not as another useless scholar, writing papers and making endless studies while the species dies out. Tell me, Len Wong. What could be more beneficial to the endangered Asian wild ass that you wish to save than a healthy and very fertile female ass?"
It took Len a moment to realize what she was saying, and by then his ears had already stretched up and grown fur. Reaching up, he grabbed one and felt both with the fleshy ear and his fingertips. This was real! Suden fear washed over him, and he started to yell - only to give a coarse bray that made the audience laugh.
His clothing crumbled away suddenly, revealing a slender body that rapidly swelled out and sprouted hair. His chest and belly ballooned out, and his arms and legs altered rapidly into short equine legs.
He fell forward as balance changed, catching himself easily on his new forelegs. The audience applaused as a black stripe shot down his back, bordered on each side by a thin band of white. Twisting around, he looked at himself with wide-opened donkey eyes. He was mostly reddish-brown, with a white underside. Then color faded almost completely, but not enough to keep him from seeing the ponderous black penis and sheath of a jackass dwindle suddenly.
Strange sensation filled his body, especially his butt, and Len Wong shivered in sexual pleasure and desire as her new donkey cunt became slick and hot. She was in heat, and needed a male badly. Confusing thoughts of having two legs, of being human, of being male, were brushed aside as the new jenny ass caught the scent of many healthy jacks close by. She brayed invitation, and heard a chorus of willing answers.
"There we are." Madame Illusia motioned for Thomas to lead the female off. "The Asian Wild ass is no longer quite so endangered. She will live a long and healthy life, carrying and nuturing many fine new foals."
