"Ok. alright let me be the pony giving rides!" screamed Paul.
Zepar seemed willing but not as happy with a glowing smile he sported with his last offer for Paul.
"Be you then blessed to live the normal life in coomon form a pony shall you be, gelded without the balls to be a real male of the spices!" said Zepar aloud.
Asif the pain was not bad enough it now began to make his guts as if on fire. Falling to his knees Paul looks up toward Zepar.
"Is this agony necessary?" he groaned out.
"For me to know you will respect what you become, yes!" replied Zepar.
The fire raced from Paul's gut to spread down legs making the muscles cramp and tendons flare. Jerking backwards Paul laid out on the black tile floor having his body and frame racked with violent convulcions.
Even the Centaur Boot turned his body around not wishing to be reminded of the pain and agony he endured to become the half animal creature Zepar changed his body into.
Paul was racked with hellish agony put never lost consciousness. As arms twisted and grew they became forelegs ending in a small neat shaped hoof.
Shuddering human legs grew broader and his groin became deeper. Paul's testicles grew to the size of Kiwi fruit and were suspended in a tight black leathery sack. The hog sheath which had originally begun to grow in, now softened and growing much wider took on the sheath type of an equined form.
Shivers of chilling pains made the thighs and legs change to hunch Paul down. His feet grew longer and longer as heels became hocks and toes a solid hoof.
The demon overlooking his evil work smiled as Paul screamed out when the tailbone sprouted out over his now hairy butt. As the bone bored out and grew long it spread wide Paul's buttocks laying bare his asshole to the sun and wind.
As the tailbone was covered with flesh and hairs tickled as the sprang forth Paul's backbone began to enlargen and lengthen all at the same time.
Reaching his hind legs out to their farthest stretch possible Paul strain to stretch his forelegs as well. A popping sound was heard as disc after disc in his strengthened back played into place. Yet the worst agony was still to come.
The legs and body having taken their final reshaped forms it was now the time to make Paul's neck to conform to equine configuration.
Pop snap, pop sanp, one by one the new vertibra of an equine neck sprang into sucession making Paul's neck look three feet in length. Then as if being embalmed with wraps of new muscle the bones collapsed into an 's' curve while the muscle thickened making Paul's neck take the hard muscled form on a pony like neck.
As the neck formed itself up to be able of supporting a large boned head Paul's human skull began to wrench about with change.
The ears were first to be drawn upward while eye scokets spread wider and nasal bone structure blosomed in size and length. His nose spread wide and upper lip merged with the soft tissues of his nostrils. A lower lip made now for grasping at food, cupping it up and into the mouth filled with block slab teeth.
Paul groaned and would have cried tears but those for a pony was not there to be. His breathing took on new actions as heart pumped harder and internal organs accepted a new way of life.
Slowly Paul stirred and moved his legs as pains calmed and the agony of demonic forced transformation subsided. The floor being quite slippery to solid pony hooves had Mister Boot walking over to help the new pony animal to his four feet.
"Congratulations your change of species is now complete!" said Zepar.
"You are a stocky fine form of a pony stallion there, Paul!" said Mister Boot.
Paul looked up with dark brown orbes of eyes peering around a giant nose as nothing he'd known before.
"Again I congratulate you for weathering the forces needed to change the body from one species to another! I was thrilled to put upon you your new and enlarged testicles. I felt an honor about you as the change completed and since you were strong enough to live on I will gift you those two big balls for a short while. Oh, but in time you will be gelded making the bold stallion into a timid and calm animal. Yet for your first month or two as a pony the betterment to make one accept his pride in life is to grant you a time at stud. So not wasting your time of play and honor any longer, Mister Boot please do the right thing and release my fine recreationed' pony into the wide world beyond the museum, please!" ordered Zepar.
Mister Boot looked down at Paul as he looked upward at the tall Centaur.
"Be you off and find you life to be free and one of great joy!" wished Mister Boot as a new male pony walked out the barn museum and into the grassy fields of the great outdoors.
