“NEIGH! NEIGH! NEIGHHHHHH!”
Your loud, breathless cries echoed around the barn as you continued to rock in time with Jessie’s powerful thrusts. By this stage you were actively pushing back against the massive stallion on top of you, allowing him to stuff his dick right up against your cervix as your mare juices squelched out around its length. Every inch of your body now rippled with pleasure as you savoured the feeling of the massive cock buried inside your sloppy mare cunt; simply adoring the way it tickled and stretched your sensitive inner walls as you shuddered in pure ecstasy.
As for Jessie, he too was clearly loving the passionate rutting as he continued to thrust in and out of your dripping wet folds. You could sense the urgency in his actions as he roughly forced his hips forwards, causing you to instinctively move with him as he speared into you and pressed his aching testicles close to your vaginal entrance. As he did so he also made sure to grip you tightly with his forelegs, thus keeping you safely pinned in place as he had his way with your young, fertile body. Happily, this show of strength and dominance simply turned you on even more; thus multiplying the immense pleasure already coursing through your veins as you relished the opportunity to be fucked by such a handsome stallion.
As a predictable result of such a passionate performance, you were soon able to sense that a powerful equine orgasm was rapidly building inside you. Your pussy seemed to burn white hot as it started to flutter and spasm out of control, clearly in anticipation of being flooded with Jessie’s load as your inner walls wrapped tightly around his eagerly pumping shaft. In response, you felt the massive organ starting to shudder and jerk around inside you as it moved at an even quicker pace.
Not long after this, you let out another shrill whinny of excitement when you felt the tip of Jessie’s cock starting to flare inside you. This then prompted the stallion to urgently push his hips forward, such that his testicles were left pushing against your vagina’s stretched outer folds, while the expanding tip pressed demandingly up against the entrance to your eagerly-waiting womb.
With everything now in position you knew this was it. You could feel your mate’s dick trembling as his balls churned with potent stallion seed. This was what you had been waiting for. You were ready to receive your mate’s precious load and to become the mare you were born to be…
“NEIGHHHHHHHHHHH!”
For a brief moment, you thought the immense whinny coming from above you signalled Jessie’s climax. However, you soon realised that this was a cry of outrage rather than pleasure as you felt his heavenly cock beginning to slip back out of you!
Once you realised what was happening, you quickly turned to see what was going on. To your absolute horror, you now saw that a couple of burly farm workers had wrapped ropes around Jessie’s neck and were now pulling him back away from you! You tried to stop them, but soon you felt that you were being similarly restrained as a few more pairs of hands started to pull you out from under the stallion above you!
For the next few moments, time seemed to slow as you both struggled to finish your mating. Having been so close to orgasm, it felt like your soul had been ripped away as you let out a mix of angry and pleading whinnies. Sadly, in spite of your best efforts, you could still feel Jessie’s penis withdrawing inch by inch. This continued until finally, with a wet *pop,* the mushroom-shaped tip of Jessie’s cock also slipped free; leaving you gaping open but feeling empty inside as your vagina winked desperately for attention.
“Awwww, I’m sorry to ruin the fun dear,” a familiar female voice said as you felt a hand patting your rump, “but I’m afraid you still have work to do as a human. I nearly have all the footage I need; but first we need to make it look like you both went all the way so to speak…”
Hearing this made you look back in outrage as your head spun in confusion. Your eyes then fixed Nat with a hate-filled glare as she smiled back at you smugly. How dare this bitch deny you the pleasure and satisfaction that your body craved. You didn’t care what you had to do. You were desperate to get back to Jessie and to finish fucking him like your life depended on it; even if it meant taking on all of the pesky humans that were trying to stop you.
With this in mind, you whinnied out to Jessie desperately as you tried to buck and kick at the men holding you. At first it seemed to be working as you caught one farmhand off guard and sent him tumbling to the ground. However, it sadly wasn’t long before you felt the ropes around your neck and hooves pulling even more tightly. These were then fed through more of the steel restraints that had held you earlier, thus ensuring that you were soon completely immobilised as you cried out in dismay.
“There, there dear,” Nat said in mock concern as she ran her hand along your neck and up to where she could play with your ears, “I know this must be heartbreaking for you. All I can say is that you, Jessica and Kevin will thank me when you are all back to normal. However, before that can happen I still need to convince the Zoo that you have been changed for good, and for that I will still have to help Jessie finish what he started…”
With that, Nat slowly sauntered away from you and over to where your frustrated mate was still snorting and bucking in rage. However, the big stallion seemed to abruptly halt his tantrum when he felt a hand suddenly grip his still fully-erect penis!
Jessie looked down in confusion, only to see Nat now stroking his cock lovingly as she gently squeezed the enormous mottled length. Soon, this contact seemed to have the desired effect as Jessie stopped resisting. Before long, the big stallion was left shaking and neighing softly in place as Nat gradually increased the tempo of her movements; leaving you staring dumbfounded as you struggled to process what the hell was now happening.
“Yes, that’s it big boy,” Nat said as she turned her attention to Jessie’s testicles, “you must be close to exploding with passion. Oh, I bet this feels good,” she said as she cupped the stallion’s balls in her hand and gave them a firm squeeze, “soon you will burst if we don’t relieve the pressure somehow. Don’t worry dear, I’m sure THIS will help…”
As Nat said this she darted back towards Jessie’s massive penis as it bobbed around beneath him. This time though, Nat made sure to ramp things up a gear as she rapidly moved her hand up and down the entire length of Jessie’s shaft, making the startled horse whinny as she pumped his cock much more purposefully than before.
While this was happening, you could only watch in dismay as Nat continued her lewd handjob. That should have been you standing there pleasuring Jessie, but instead you were left feeling abandoned and empty as your vagina continued to sadly drip with sticky fluid. You tried desperately to entice him by whinnying needfully and presenting your massive ass to him. But tragically you knew your special moment had been shattered. Now Jessie was completely under Nat’s power; leaving you watching helplessly as he once again started to near the immense climax that you had almost brought about earlier.
Sadly, this time there was nothing to stop Jessie as his dick once again flared and started to shudder. Seeing this made you cry out in dismay as you begged your captor to help put that heavenly member back inside you. Instead, Nat merely chuckled in amusement as she moved her hand even faster up and down over Jessie’s trembling penis. Seeing this made you want to cry as your body continued to ache and burn painfully in need. You wanted Jessie’s cum so badly, which is why you were so horrified when it started to erupt over the floor beneath him instead of inside your eagerly waiting loins!
Jessie let out a loud bellow of release as jet after jet of salty semen splattered onto the straw-covered floor beneath you. Seeing your mate’s impressive load going to waste made your need intensify as your vagina continued to open and close itself hopefully. Sadly though, it was soon obvious that you would be bitterly disappointed as Nat instead pointed Jessie’s dick down towards the floor; thus causing a disgusting white puddle to begin forming as a steady stream of gloopy semen continued to fill it from above.
After what seemed like an eternity spent ejaculating, Jessie’s massive testicles finally started to dry up as the torrent of cum subsided. Soon, this steady stream was reduced to a wet trickle, as the massive cock began to soften and droop down towards the floor like an elephant’s trunk.
As for you, you were left staring in sadness at the big, sticky puddle on the floor as it started to curdle and spread outwards. Even a few drops would have been enough to put an end to the mare’s heat blossoming inside you, but instead you were cruelly forced to watch as you were denied your final release.
Upon noticing your obvious distress, Nat moved to comfort you as she stroked your mane and rubbed your nose lovingly. “There, there, don’t look so glum dear. Trust me, soon you will be glad that I prevented you from damning yourself and your sweet girlfriend over there. Now though, there is one last thing I must do to put the cherry on top of this little performance…”
In response, you could only stare in silence as your head continued to spin in confusion. You had been on such an emotional rollercoaster that your brain felt like it had been completely scrambled. From the horror of your transformation to the ecstasy of your mating, you were now left feeling both distraught and deflated as you continued to miss having your lover’s cock wrapped inside your velvety folds.
You continued to think about the cruel reality of the situation before you actually registered what Nat was now doing. Strangely, the sadistic woman was now crouching over the puddle of spent semen that Jessie had left on the ground beneath him. Weirdly, she was busy dipping three fingers into the sticky white pool of fluid, apparently in an effort to collect it as she allowed it to run messily over her outstretched digits.
Seeing this was already strange enough, but things soon got even weirder when Nat stood up and moved over to your backside. Then, you let out a soft neigh of surprise when you felt a hand gently beginning to brush between your legs, particularly the area just below your pronounced vaginal mound. You soon realised what Nat was doing, but you couldn’t figure out why as you felt her liberally coating the area around your dark teardrop-shaped opening with a healthy dollop of Jessie’s sticky cum.
You remained puzzled by this latest humiliating act as Nat returned to the sticky puddle for a refill. This time, when she returned to you she actually made sure to smear the strands of semen over your vagina itself, leaving the dark puffy lips glistening with wetness as they continued to wink open hopefully. Nat even deposited a healthy white blob of fluid just inside your slick vaginal channel, which then started to ooze out slowly as it joined the growing mess between your legs.
Nat continued to add a few more handfuls of Jessie's spent seed to your backside, before she finally seemed satisfied and pulled away. You still didn’t have a clue what she was doing, but when you saw her whip her camera back out for a close-up shot of your cum-streaked backside, you knew it couldn’t be good...
"There we are," Nat announced dramatically as she aimed her camera at the stickiness between your legs, "it looks like your former girlfriend filled you up well. Soon you will be heavy with your first foal, if this mess is anything to go by!"
Hearing this only added to your confusion, but sadly you were soon distracted by the feeling of Nat's fingers gently rubbing and teasing the tight feminine slit beneath your tail. Tragically, you still missed having Jessie's cock inside you as you felt your pleasure slowly ebbing away. The magic of the moment had been utterly ruined, leaving you feeling empty and unsatisfied as your vagina gradually contracted and grew tighter, given that it was no longer in use. On the plus side though, your diminishing lust did allow your humanity to begin reasserting yourself. Your head was still a scrambled mess, but you had enough awareness to feel increasingly concerned about what Nat was now up to.
"Mmmmmm, that's it," Nat continued as she stopped to casually scissor your pussy lips apart, "already so tight and eager for another round. Don't worry girl, once your changes are locked-in you will have all the stallions you could ever want. Forget that you were ever human, or even male. Now you are Princess; and you will remain like this for the rest of your life!"
Hearing this instinctively made you whinny out in protest, however deep down you knew there was more to Nat's behaviour than met the eye. Everything she had said about her 'performance' made you wonder whether this whole thing had been part of one big act the whole time. After all, if she had truly wanted you to end up as a mare for good then she wouldn't have stopped you from mating with Jessie. You remembered that Nat wanted to claim the Zoo's reward for re-capturing you, but maybe she had figured out a way to do this without actually turning you into Princess for good...
"... and... that ought to be enough," Nat announced in answer to your question as she moved back towards your front, "we should be able to cobble something together with the footage we have.”
Upon hearing this you just stared at Nat dumbfounded, still struggling to process what was going on.
“I'm sorry for what I put you and your friends through,” Nat continued as she looked into your eyes, “but I didn't have a choice after you so bluntly refused to cooperate. I would have told you what I was up to, but having realistic reactions from you three was necessary to make my performance a convincing one. This should mean that I end up being promoted to the Zoo's board of directors, while you, Kev and Jessica should all be back to your old selves by the morning. Then, perhaps we can start thinking about rescuing your family, as well as the countless other victims of the Zoo's curse."
Nat's words took a moment to register as you struggled to come to terms with what you had just heard. Everything including your transformation and mating had all been part of an elaborate ruse to fool the Zoo?! But if that were true then why had she gone to such great lengths to humiliate you and the others, and why had she seemed to enjoy it so much? Either Nat was an Oscar-worthy actress or she had had more fun than she was willing to admit.
You continued to ponder this disturbing theory as Nat rounded up Jessie and Petunia. Like you, it seemed that both of them had regained some of their human awareness as they both exchanged worried and confused looks. Seeing this proof of their surviving humanity made you feel slightly uplifted, though you wondered how much damage had been done by Nat's sick performance. The expressions on both of their faces told you that they were both ashamed and embarrassed by their ordeals, something which you could relate to as you felt your equine vagina still sitting proudly between your legs.
"There we are," Nat said as she slipped ropes around your necks and unfastened your restraints, "now you can all have a good rest until your changes reverse. In eight hours or so you will all be human again, so we had best make sure you are comfortable for the night."
With that, Nat escorted you outside and led you over to another small building across the courtyard. Once inside, you and Jessie were each given separate stalls, presumably so that you couldn't continue your mating from where you had left off. As for Petunia, she was placed in a small pen with a few other nanny goats. It was clear that she didn't like her new companions as she bleated out in annoyance, however she soon seemed to settle down once she found some tasty dinner to munch on.
Ultimately, you ended up behaving in a similar fashion as you ate some hay that had been left out for you. You did your best to relax as you swished your tail idly, but the throbbing in your vagina had never fully dissipated; leaving you with a nagging itch that just wouldn't go away. You knew you just had to last until morning, but this was easier on paper than in reality as you struggled to distract yourself from the feeling of your own heat burning inside you.
Regrettably, your previous experiences at the Stables told you just how potent a mare’s oestrus could be. You knew you couldn’t ignore it, which meant that this had the potential to be a very long night indeed...
