Jenny felt a tingle of shocks run out of the medallion. She picked it up from off her breasts where it bounced around on it's long chain. The strange pulses could be felt in her fingers as well.
Giggling with delight in the find of her most personal treasure she walked back to camp. The trail back into the trees was hot and humid. As she walked along Simon met her as he led one of the pack mules back to the dig.
"Hey Jenny did you here we broke into a burrial cave. Wow, all the wildest stuff, a mummified woman, a gold challis', urns, all kinds of artifacts."
"No I'm walking back to camp it's so hot and well this digging is borring me!"
As Simon walked away leading Jonus the only male mule in ten they had shipped in to carry what was found, Jenny turned to watch the big butt sway as he sauntered along.
"Well Jonus won't get bored, Hell he fucks each of the female mules nightly. No testicles but horny as if he were a stud. Must be nice to have nothing else to do but hump a bunch of willing pussies!"
As Jenny walked she felt more sparking shocks poke at her chest from her new toy. Stopping, she again pulled it out to look at the ornate writings and beautiful stones decorating it's edges.
A big sigh, bored I'm so bored! Picking up her toy she looked at it and said, "As Jonus' fucks with mules I wish my sex appeal was simular to those in camp, even better!"
Suddenly a greenish glow began to expand from the medallion she wore. A auora of green filled the area around Jenny. She began to scream yet even as she did the sound quickly changed. Her third scream trailed off into a whinnie as her head and neck became more equine.
Her eyes glared at the sight of dun colored hair sprouting on arms and legs. Her golden brown skin turned darker and then jet black. Shaking her head as small pains ran through her brain she felt the fullness of a horse's mane.
"This can't be," she told herself as chest and belly expanded. Arms were now fore legs and her pouty hands became solid black hoofs.
An hour past and Jenny stood flicking her long black tail and shaking the flies from her mane. Thoughts of human exsistance seemed foggy and her ner feelings and instincts began to override Jenny's memories.
The smell of mules in the air, turned Jenny around as she clopped alone toward the dig.
As she stepped out from the trees Doctor Simmons was first to see the tall horse. "Simon, Frank, catch that horse if you can?"
Both students ran toward Jenny. No cares she stood her ground as the boys approached. A halter smelling of mule was slipped over her head. A shake of her mane and all seemed just fine.
Doctor Simmons stepped over, "My word boys where do you think this big fellow came from? Lets put a saddle on him and see if he's ever been broke to one?"
Frank grabbed a saddle and slung it over Jenny's back. She jumped as it slapped on her back put stood knowing her friends and the Doc meant no harm.
Frank climbed up on Jenny and walked her around, "Seems he's saddle broke, wow such a fine animal this deep in the forest!"
"Well Frank sice he trusts you so much put him in the coral with the jennies till we make for camp."
A gate opened as Jenny joined the jennies in the coral. Jenny sniffed the scents of all the mules. "Damn it their all females, I want to have sex, sex, sex!"
Frank walked over and stepped up on the coral fence. "Hey big boy your mine and I might have you shipped stateside when we head for home." Patting Jenny's muzzel he smiled and walked happily away.
"Big boy, whats this big boy crap can't he tell a mare from a stallion?"
Just then a jenny mule strolled over and dipping her head down slurpped a wet lick in Jenny's groin.
"Hey!" Jenny jerked her head around at the strange touch. Her view saw a horny jenny mule turn and display her black crusty vulva and lift her tail.
Jenny's sight though now in scenes of gray watched a long black horse cock fall from her very equine groin. Longer and stiffer it became until rock hard she felt it churn for release.
"This is crazy! Thought Jenny I'm a horse and a stallion too!"
The jenny mule brayed softly, her butt wide open for a stallion's advance. Head hung low she was in submission to he lover.
Jenny looked at the mule's butt and winking vulva. Suddenly stallionhoed took over and in a bouce she mounted the mules rump.
Wiggling ever forward she poked the end of her long horse cock into a hairy butt. Stepping closer a little she stood up as straight as possible. The cock end poked twice more and then touched a warm wet slime covered vulva.
In a thrust Jenny entered the mule's vulva, the head of the uretha pushing aside the black lips of sex. A left half step and the member sunk deep into the anixous jenny mule.
Jenny the stud felt strong muscles inside the mule tighten down of her sexy shaft. Plunging away she flexed her pelvis stroking the sensal cock over the heart stings of a sex longing mule.
Jenny had enjoyed sex with many a coed, but this raw animal sex was nothing that could compare. A new realization as she now felt sex from a male's point of view, Jenny twisted and plunged enjoying the moment.
Jenny's over sexual desires and her animal form caused the mating ritual to last for over an hour.
As Jenny finally dismounted and stood with vagina juices dripping along with semen from her shaft, she turned to see Wilma Jensen kneel down.
Wilma as horny as Jenny could not stand to watch the orgy. She kneeled in the dust of the coral and reaching under Jenny touched the big cock.
Wilma, mouth opened thrust the cock into her willing mouth. Jenny bet her neck around and stood quiet. Pleased as her horse self to be thrilled by this suckling she stood and enjoyed.
Jenny's cock still hard and rigid filled the round faced Wilma's mouth. Suck, suck, went Wilma the feeling more than Jenny could stand. A wiggle and she felt a surge.
Wilma began to choke as a quart of precum and sticky semen flew in and jammed down her throat.
Wilma sat coughing on the ground as Simon stepped over. "Nice job Wilma, maybe later you might try Jonus or even me?"
Wilma, her face and chest covered with Jenny's semen walked quickly away. "Hey big boy you sure get the sexy females going around here! I'll send Jenny over maybe a cock as big as yours could satisfy that stupid bitch?"
Jenny stood with desire in her stallion brain but she began to wish she wasn't a horse anymore. "This was neat but I want to be me again, Medallion! MEDALLION?????
Sunddenly she notice that the chain and Medallion was gone from her neck. Quickly she looked around the coral, but no sign of the ornament.
Then her perky hearing heard up the trail Simon say, Hey look what I just found!"
Jenny felt the true terror of being less than satisfied with life. She knew that the Medallion had changed her and without it around her neck she was a stallion permanent.
