You could only stare in sick fascination as the stallion started to work his hips, making his cock begin slowly thrusting in and out of his mate. The chestnut filly grimaced as she did her best to contain the equine lust that now gripped her tightly. Despite this, her true emotions were betrayed as she held her posture and lubricated her pussy so that her mate could move inside her with ease. As a result of this the stallion’s pumping action started to produce wet squelching sounds as various fluids were forced out around the base of his meaty cock.
As this was going on you could sense that your own arousal was also starting to build. Being so close to such a mighty stallion was making it hard to think clearly. Your tail was now bolt upright with a steady stream of your feminine juices currently oozing out of your throbbing pussy. Witnessing the building passion that was coursing through the filly was making you envious as your own vagina remained empty and in urgent need of attention.
Your situation wasn’t helped when you sensed that Vicky had moved to look at your rear-end. You then gave a surprised neigh when she started to gently tickle the outer lips of your own swollen sex. Your whole body shook with need as the soft caressing on your slick folds made your body want more attention. You started to imagine yourself in the chestnut filly’s place; happily welcoming a long, stiff stallion cock into your sloppy wet folds.
Vicky continued to rub and tickle your needy sex until she sensed that the coupling in front of you was about to finish. Sure enough, the chestnut filly gave a shrill cry of release as she shook with a powerful orgasm, with any traces of resistance now having fully evaporated. This prompted the stallion on her back to stuff his dick forward as hard as he could, making sure that his flaring tip was pressing right up against his mate’s cervix.
The organ remained lodged deep inside the filly as she continued to tremble in delight. You sensed that the male was busy pumping his load deep into her depths as his cock and balls flexed and twitched in unison. This was confirmed when a white stream of sexual juices suddenly flooded out of the filly’s stretched orifice and splattered over her hind legs and the floor below.
The stallion then rested for a few moments, giving his virile sperm time to fully penetrate his mate’s fertile womb. He only withdrew when he was satisfied, exciting his mate slowly with a wet *pop* as he slipped free. A fresh wave of cum then poured out behind the filly as she struggled to hold the sheer volume of semen that now filled her passage.
With the action having died down, you were left looking at the aftermath of the intense mating. The filly’s crotch was streaked with cum as more fluids continued to spill out of her overflowing pussy. As for the stallion, his dick was also left dripping with fluid as it steadily softened and returned to its sheath.
With that the mating was over. What was once a man a week ago was now trapped as a horse forever. A female horse!
With his job now done, another attendant came to escort the stallion back to his stall. To your shame you couldn’t help looking at him as he walked away, your vision once again lingering on his hefty testicles until he disappeared from sight.
With the stud gone, you finally started to return to your senses. You looked around the courtyard to see what else had been going on. It seemed that three of the other four females had also received a healthy amount of potent stallion seed, judging by the wet stains that now lay between their legs.
The only horse that had yet to be claimed was the defiant white filly, though it looked like she would soon be sharing the same fate as the others. Despite her obvious outrage and continued defiance, the distressed filly was currently being impaled by her mate’s enormous horse cock. The big stallion on top of her snorted possessively as he bit his mate’s neck and gripped her hard with his forelegs. He was also being helped by a pair of burly attendants who were using ropes to hold the filly’s legs apart and prevent her from kicking and bucking him off her back.
Upon noticing your interest in the wild equine mating that was unfolding before you, Vicky decided to let you have a closer look. She brought you to within a meter of the couple before she gripped your lower jaw and forced you to look closely at what was happening between the filly’s legs.
You quickly became lost in the pair’s passionate lovemaking as you watched the stallion’s cock disappearing inside his mate, all from your extremely close vantage point. Seeing the female’s pussy stretching and wrapping around his girth made you feel hot in your own vagina. You could practically taste the arousal of the two horses as various sexual juices were forced out around the base of the male’s enormous thrusting penis.
Like with the chestnut filly, you couldn’t help feeling envious as the stud continued to roughly pound his unwilling mate. You knew your body craved the stretch and penetration that the male was providing, not to mention the sticky load that was sure to follow soon. You knew it was wrong to have such wicked and selfish thoughts whilst watching a human being getting fucked into oblivion, but in that moment you couldn’t care less as your equine instincts guided your emotions.
You therefore felt a fresh pang of jealousy when the mating reached its inevitable climax. The filly gave one last whinny of angry defiance before her cries transitioned into more of a horrified wail as she started to get pumped full of her mate’s creamy white semen. You found yourself staring hungrily at the filly’s parted pussy lips as a thick stream of stallion jizz started to spill out from her depths.
The filly continued to cry out desperately as her mate kept his penis lodged inside her for a good thirty seconds, just to make sure that his seed had breached her fertile womb. After that, the stallion unceremoniously withdrew, leaving his mate shifting in discomfort and dripping with excess fluids. The horror in her eyes was plain to see now that she too had been locked into her equine form for good.
With the fifth and final filly successfully mated the action finally ended. The five former-men were now doomed to live out their lives as five simple mares.
With all of the mating now out of the way, all that was needed was for the attendants to decide what to do with them. Vicky explained the marking criteria as the attendants compared their notes. Things such as fertility, fitness and temperament were all taken into account, with only the most excellent specimens being allowed to become full-time residents of the Stables.
In the end it turned out that a beautiful arabian horse was chosen to work at the Stables, where she would be busy transforming guests and breeding with some of the best studs in the country. Meanwhile, the two horniest members of the group were promised a lifetime of stallions and sex at a local stud farm, which neither seemed too upset about. As for the chestnut mare, she was assigned to a riding school due to her docile and submissive behaviour. And lastly, the defiant white female was destined for a special horse farm that was designed to break the spirits of even the wildest of horses. From what you could gather she would be used as little more than a foal factory. Supposedly she would only be allowed to be with other horses when being bred by a stud or when nursing her offspring... although apparently both could happen in unison if the farm’s owner was feeling generous.’
With their various fates now determined, the five new mares were led away by their handlers. As the lust in your mind began to return to manageable levels, you began to feel sick as you reflected on the cruel ordeal that these people had been put through. You felt sorry for them all as they were led away like dumb animals. All of this caused you to panic as you dreaded to think about what lay in store for you in the future.
You continued to dwell on the harsh reality of your situation until Vicky’s voice piped up nearby. “Congratulations girls, this is officially the end of your training. You now know that you have nothing to worry about tomorrow. Just to make sure that you’re in the mood though, we are going to really get those feminine hormones flowing. By this time tomorrow you will all be at the height of your oestrus, which is when you will finally have the release that I can see you all crave.”
You feared what awaited you as Vicky started to lead you away. Your main thought was that since your equine heat was already unbearable, how much worse could it possibly get?
Sadly you would soon find out as you were taken to…
