A 17 year old came down from near the back "Lets see this real magic then he said". "Very well" Madame Illusia replied. "Lets begin". She whispered more strange words from her mysterious magical language and the boys clothes vanished leaving him standing naked in the tent. "Big deal" he mocked but all the same looking a little worried. "Oh we are not done yet my dear" Madame Illusia said. She carried on chanting and the boy felt very strange looking down he saw his manhood shrink and be pulled inside him, he tried to scream and run but found he could not. The changes continued as a fully equipped female reproductive system formed and a pair of DD breasts pushed out from his chest. Next the new girls hair changed colour from black to blond and grew down to just below her shoulders; next all the visible muscle melted away and her arms and legs became much more feminine. Lastly her face changed to a very beautiful female one.
"Do you doubt my power now dear" said Madame Illusia. "No" she replied. "Please change me back now". "I'm afraid I can't do that" she replied. "once a spell is cast it can't be undone, but I can make it so that no-one outside of this tent knows of the change to them you will have always been a girl, this will remind you want happens when you mock the mystical". With a wave of her hand the girl was wearing a short skirt and tube top and then was transported back home.
