Officer Georgina continued to yell as the big stallion charged along. She ordered Able to stop over and over again but he was having none of it; all he wanted was to catch that elusive mare and impregnate her. To that end he ignored Georgina’s yanks on the reins and desperate commands, instead deciding to head into a nearby forest as he homed in on the scent trail left by the needy female ahead of him.
However, the rough ride was not Officer Georgina’s only problem. She was far too terrified to realise it, but her body had started to change. The process was subtle at first as the officer’s ears became pointed and a few light sprouts of fur popped up here and there. But the more she rode the more she changed. Soon she sported a short black tail while her uniform started to get tight as her body swelled and surged with muscle.
Meanwhile Able picked up his pace as he sensed that he was gaining ground on his target. Although he still couldn’t see Jenny her scent was getting more powerful the closer he got to her. As a result, his giant penis was beginning to leak pre-cum as it stood hard in anticipation.
One side effect of this was that the stallion was giving off his own musky aroma. This previously unnoticed scent was becoming increasingly sweet as Officer Georgina’s changes progressed. Her larger nostrils flared as a cute equine muzzle stretched from her face. Her mind started to warp as the changes gripped her. As a result her vagina started to moisten subconsciously as it got the message that a stallion was nearby.
The feeling was so strong that Georgina couldn’t resist sticking one hand down her trousers, whilst skilfully keeping her balance with the other. Soon she was moaning as she pushed two fingers into her sensitive pussy. She knew that this was a strange time and place to be doing such a debauched act; but that didn’t stop her.
And as Georgina succumbed to the lust surging through her body her changes gained momentum. Loud rips echoed out as the officer’s backside and chest ballooned out of proportions. Her neck, muzzle and tail had all lengthened dramatically, while her arms and legs had started to get longer and more slender.
But Georgina was too gripped with passion to really notice or care. Soon the changes spread to her vagina itself, making it much larger, deeper and more muscular; perfect for a stallion’s thick shaft. However, in the short term this also gave Georgina more room to manoeuvre as she soon added a third, fourth and even fifth finger to her changing snatch as she frantically rubbed away at herself. Her moans got louder and more guttural as her pleasure spurned the changes onward.
In the meantime Able was still eagerly pursuing his quarry. He found it odd that pieces of torn fabric seemed to lie strewn behind Jenny as he chased her. As well as this he was starting to notice Georgina’s own scent which was now an odd blend of human and horse. He began to struggle as his rider got heavier and heavier. However he was determined to keep going as he sensed that he was getting very close to his goal.
Soon Georgina’s lustful cries were replaced with shrill whinnies as the transformation gripped her voice box. By now her uniform was gone save for a few tatters here and there. Dapple grey hairs had spread all over her body, while a black mane had grown to match her tail. Her sitting position was getting uncomfortable as her skeleton adjusted itself for four-legged movement.
Despite this, the officer still had her hand firmly lodged inside her pussy, although by this stage this was also starting to feel weird. She withdrew it slowly, only to recoil in horror when she saw a rather sticky hoof coming out of her instead of her human fingers. However, before the startled officer could really react, she soon had another problem. Now that she was unable to grip the reins properly her balance was beginning to shift…
As a result, when Able rounded the next corner at full speed, the force was too much for the unbalanced officer and she was sent crashing to the floor. She groaned as she tried to stand, only to find that her hips had snapped into a quadrupedal orientation.
It was at this stage that the Georgina finally started coming to terms with what had happened to her beautiful body. She shivered in shock with her eyes wide as she looked at her bestial self for the first time. She craned her long neck around so that she could see her new bulky form, with her barrel-shaped belly and rounded backside. The officer felt strange as she gave her new tail an experimental swish. She then looked beneath herself, just in time to see her darkened pussy as it slipped out of sight and under her swishing tail. She felt sick as she watched two rubbery nipples emerge on her torso, capping the two mounds of her empty mare udder.
With her changes now finished, the new horse looked around at her surroundings for the first time. She was stood in a large clearing amongst the trees along with three other horses. She recognised Able who was now trotting over to greet the chestnut coloured mare that he had been pursuing.
However Georgina didn’t immediately recognise the third horse. She studied the stallion which had a similar dapple grey coat to her own. She thought something about him seemed oddly familiar, but it was only when she saw a few tattered pieces of uniform beneath him that she finally pieced it together: it was Mark!
Sure enough, Officer Mark had undergone a similar change, save for the fact that he was now a virile stallion rather than a fertile mare. Georgina soon found that she couldn’t take her eyes off him. He was a magnificent specimen with a large, powerful frame.
Her eyes were then unwittingly drawn to the horse’s enormous mottled penis as it hardened beneath him. She started to feel more strange sensations from her new mare’s pussy as she began to crave Mark’s attention. Before long she was showing him her winking folds, inviting him to come closer.
Mark seemed eager to help her out as he strode towards her gingerly. This made Georgina shudder in glee. She couldn’t wait to have him!
