"DO TELL, YOUR FANTASY, WHAT IS IT?" asked Zepar his one claw beginning to pick up off the rock.
"For as long as I can remember back, I have longed to be like a satyr."
Almost before the words were out of my mouth, the crab-like demon's claw shot forward and grabbed my extended hand. "Granted!" I snatched my hand back, but it was already too late - I could feel a powerful throbbing shoot up my arm and pulse through my entire body.
Zepar laughed, a sound that made my flesh crawl almost as much as the magic that was pulling at my very bones. Stumbling back, I stared down as my clothing crumbled away. For a moment, I thought that was all that would happen, but then my legs began to shift back at the knees, bending the wrong way as my thighs flattened and shrank.
That should have been enough to send me screaming in terror, but my eyes locked on what was between my legs. My penis was swelling and turning pink and slick, while the testicles below swelled out and darkened. A band of black skin appeared at the base of my thickening shaft, and shot up first as a foreskin, and then pulling to my belly to form an animal sheath. The shape of my penis altered, no longer human, and slid into its new home above a heavy black sack that now held balls the size of tangerines.
The sensual thrill of this new organ almost blinded me to the rest of my body - but I realized that more than just my sexual equipment had changed. The legs on either side were now fully those of a black billy goat, ending in cloven hooves. Feeling my butt, I discovered an equally goatish rump and tail.
Exploring fingers also found horns on my forehead, and pointed ears. My face felt different, and my body was thinner and oddly boyish looking. Staggering on my new hooves, I found my reflection in the window of one of the cars and gasped. I had become a young teenager! My face looked about 15 or 16, protruding slightly so that I gave the impression of a goat without losing my human features.
Zepar laughed from his pit. "THERE YOU ARE. A YOUNG SATYR. NO WOMAN, NO MAN, NO ANIMAL YOU DESIRE WILL BE ABLE TO RESIST YOUR LUST. NOW YOU WILL RELEASE ME. OR YOU WILL FIND MY GIFT BECOMING A CURSE."
