As the couple followed the dirt road towards the clearing, Abby’s body gradually became more equine. The first few changes were subtle, such as the pointing of her ears and the steady spread of rusty brown fur across her body. But the process soon became more dramatic as her body started to gain mass while a tail sprouted from her backside.
Abby didn’t seem to notice, clearly too busy reliving childhood memories of riding little ponies through the countryside. She had wanted to get back into horse riding for a long time, and unbeknownst to her, this dream would become a reality much sooner than she expected.
As for Jenny, she was still focused on her mission. Soon the ache in her loins would be gone and she would get the chance to enjoy being a horse, and hopefully one day a mother. Jenkins’ voice continued to nag the mare at the back of her mind, but it was just a drop of resistance in an ocean of lustful thoughts.
The couple continued along the road. Abby was getting heavier by the minute as her chest and backside developed powerful muscles. She lost her grip on the reigns as her hands and feet fused into hard equine hooves.
Jenny began to struggle as her rider gained more and more mass. She knew what her reward would be if she saw this task through to its conclusion. And so the mare kept pressing onwards as her wife became less and less recognisable.
Abby’s changes soon began to accelerate once her face started to morph into a more equine shape. Her face stretched out, new teeth began to push out their human equivalents and her nose and mouth became much larger. Her new nostrils flared, which enabled her to register a much broader spectrum of smells than she could as a human.
Jenny was starting to crave her reward more and more as she started to tire. She hoped to help the changes along using her own body in any way she could. Her vagina had continued to wink rhythmically since they had left the stables. Her juices now coated her inner thighs and hind legs as her arousal continued to build. Her sweet aroma was being wafted around by her tail as she whinnied out lustily. She was gagging for her pussy to be filled by a stallion’s cock, and she prayed that it would happen soon.
Luckily for Jenny, her scent quickly started to have an impact on her wife’s mentality. Jenny looked back when she heard Abby moaning above her. She watched as Abby rubbed at herself with one of her new hooves. It was an awkward action, but it had the intended results. As Abby’s own arousal built, her body underwent another dramatic change. Where she rubbed, her flesh began to change. Several large growths began to swell larger, seemingly having come from inside her pussy. Two of the shapes became more rounded, while the third developed a much more pointed shape. It was soon obvious that these growths were a developing set of equine cock and balls. Abby’s new equipment kept growing rapidly as she continued to rub her lengthening shaft. The new genitals released their own musky smell into the air, which soon found its way to Jenny’s nostrils.
The intoxicating smell made the mare shudder. Now she could finally satisfy her lustful urges. Jenny carefully helped her wife slip off her back as the last few changes neared their conclusion. Soon, Abby would be a handsome stallion; and a very virile one by the looks of it.
Abby’s new hooves thudded to the ground as she dismounted her husband, whilst the last few alterations took place. The last few patches of her pale skin were soon replaced by rusty brown fur. Her face also underwent some minor alterations as her muzzle finally reached its proper proportions.
However, Abby was far too focused on her new stallion equipment to really notice. Sadly, she could no longer pleasure herself now that she had adopted a four-legged posture. All she could do was watch, and feel, as her new genitals continued to grow. Her new balls began to feel heavy as they swelled full of equine seed, while her cock extended beneath her as it gained a mottled texture.
Before long the changes were done: she, or rather he, was now a mighty stallion.
Now, with his transformation out of the way, he could start getting down to business. A feint voice in the horse’s mind tried to convince him that he was still a woman, not some dumb horse. However, in his lustful haze, all the stallion could think about was satisfying his primal urges to reproduce, and luckily there was a mare already waiting for him.
As for Jenny, she had gradually become intoxicated by the new stallion as his changes had rounded off. She couldn’t help admiring his elegant shape, his powerful muscles and his alluring musky scent. Added to these was the sight of his new male junk which was already rock-hard and dripping pre-cum.
Inside Jenny’s mind, what remained of her human consciousness screamed out in horror. Any thoughts of escaping or helping her wife were drowned out by her need to be mounted and impregnated; in order to one day sire this stallion’s foals.
Sadly, what remained of Jenkins could only observe as nature took its course…
