Jenny did as her equine nature had so very much insisted. As a stallion the mounting of mules had her sexually enthralled. Simon watched and began to feel an empathy for the jenny mules. The inner lust of becoming a mare was overriding his manly self.
The noise in the camp and the notice he was missing caused two of their friends to come for mounts. The realization of another horse in the corral made the boys wonder.
The ride over the countryside gave Simon a good sweat. Upon the return to the corral he and Jenny were cooled down and the sweat rubbed down using fresh hay. Now both horses smelled even to themselves as horses which as evening approached brought on desires of sensual play.
The daily life of an animal is simple in work and pleasures. Simon and Jenny both began to slip into the daily norm of horse lifestyle. As each found their place in the beastial family framework their human identity began to slip away.
A week and then two more and both horses had stopped writing to the other. Now more often when they returned to the corral after a day's use they milled around in a mindless way.
The summer's dig was now coming to a close. The professor summoned his group together and prepared for the plane flight home. As the last evening came a all were having a party the mules began to bray and kick.
Frank heard the noise and walked down the short path to the corral. As he got close he saw an amazing sight. The hardy mare which he had so many times riden these past weeks was melting down into a smaller form.
Frank stood watching from the tree line as he saw Simon beginning to reform into his human self. The amazing sight was bettered as now Jenny began to appear where moments before the big stallion had stood.
Frank waited to the last minute and then stepped out into view of his two naked and now human friends.
"Well I see the two of you had a good time while we all worked our butts off!" said Frank in a nasty voice.
Simon looked up to see Frank and putting his arm around Jenny's shoulder walked themselves closer to Frank.
"Indian magic is all I could think of as I watched you both become human. It's been weeks since you both disappeared! Now the truth can be known, I can't wait to tell the others." said Frank with a grin.
"Who'd believe you that we were horses for these many weeks?" asked Jenny.
"Frank, your going to do and say nothing about this!" warned Simon.
Frank shook his head as to say 'noway' and turned around to walk back up the path to join the party with big news.
Simon stood watching, then had a demonic idea. "I wish Frank to become Jonus the mule and Jonus to replace Frank as a kind and friendly human!"
Jenny turned a gave Simon a scowl as the medallion glowed bright.
Frank stopped in his tracks and a dim glow halowed about his head. Suddenly Jonus the mule began to bray! Simon looked at Jonus to see the sign of a halow dimming as now Frank and Jonus had exchanged bodies.
Jonus now having a human mind and body walked over to his previous masters. "Thank you both for giving me this form! I was that mule and now have joined your herd. I have a lot to learn about being like you and hope you will help me along," said Frank.
Back in the shadows a mule brayed, it's still human thoughts were fully realised of his placement into the dirty male mule he had so many times led down the trail loaded with stuff.
