You remained frozen in fear as you locked eyes with the big black stallion. Memories of your transformation and subsequent mating by the lake came flooding back as it looked like you would soon be receiving Harry’s seed for a second time. Judging by the hunger in his eyes he definitely seemed eager to give it to you as he gradually approached.
Knowing that it would all be over if Harry got on top of you, you made sure to keep your front facing him as you defensively backed away from him. However, the relatively short rope that was securing you to a nearby tree didn’t give you much freedom to move, meaning that you didn’t have far to retreat before you could go no further.
As Harry closed in on you, Vicky seemed just as eager to see you mated as Harry was. “Oh Princess, why must you be so defiant? Don’t you remember any of your training or how good your body can feel? You must remember how much you loved being ridden by Harry? Just give in and you will have a wonderful life with darling Jessica over there.”
You looked up when you heard your girlfriend’s name. She looked back with a sad, but still loving glint in her eyes. Now that Jessica was stuck as a horse, part of you didn’t want to leave her alone like this. ‘No!’ you told yourself, you had to escape and get help. You were a human being!”
With a fresh surge of strength you reared-up and flailed your hooves at Harry as he came within striking distance. Sadly though, the big horse barely seemed to flinch as he moved beside you and attempted to mount you. Your movements became more wild and frantic as you fought desperately to avoid your impending doom.
However, despite your heroic effort it soon became apparent that being so close to a stallion when you were still in heat was having severe consequences. Despite your protests, your tail was now bolt upright as enticing pheromones and sticky fluids seeped out of your furiously winking vagina. You also couldn’t help breathing in deeply as Harry’s own scent invaded your nostrils and turned your body on even more.
All of these sensations started to weaken your resolve as your mind was invaded by the dirty desires of a filly in heat. You knew you could finally be rid of the infernal fire in your loins that had now returned in full force. You wanted Harry’s long hard length to stretch and fill your empty, needy pussy. And you also wanted the sweet rush of orgasm and to be pumped full of his sperm-rich semen. You knew it was wrong, but your body’s instincts didn’t care as you started to lose all control.
Vicky chuckled as she sensed that your will was breaking. “That’s it Princess, give in to your instincts and submit to your mate. Soon you will be with Jessica forever, doesn’t that sound good?”
As much as you hated to admit it, your answer would almost certainly be ‘yes.’ You grimaced as you tried to hide the lust that was building inside you, but you knew that you wouldn’t be able to hold out much longer. Already your attempts to buck and kick at Harry had dwindled to nothing as your whole body now trembled in barely-contained need. You hated what was happening to you, but your urges were becoming far too powerful to ignore.
With one last whinny of defiance your resistance broke and your equine side asserted its dominance. You now didn’t fight what was happening as Harry reared-up and placed his forelegs over your body. He then began to shuffle around to your rear as he scrambled on top of you with his hooves. In response you acted like a good filly by spreading your legs and revealing your sloppy wet cunt to your soon-to-be-mate.
As Harry did his best to line things up, Vicky sauntered over to your front and held your head in her hands. “Good girl Princess, I’m glad you were finally able to see sense. Soon your first heat will be at an end and you will be able to live the stress-free life of a broodmare.” Hearing all of this made you want to bite Vicky as she caressed your muzzle. However, you ultimately didn’t as you wondered what the point would be. It would only result in a fresh wave of punishments for yourself and Jessica. You couldn’t avoid your fate; you would soon be a horse forever. Why fight it any longer?
You neighed softly and licked out at Vicky’s hands as she continued to stare into your eyes. Meanwhile, Harry had finally moved into position and was busy probing for your vagina’s entrance with his enormous mottled penis. After a few stray jabs he finally struck gold, causing you to cry out in delight as your pussy welcomed Harry inside for a second time.
You continued to moan and shudder in enjoyment as Harry steadily walked himself forward, allowing him to ease his giant penis deeper into your warm, wet tunnel. The friction generated against your fleshy inner walls sent jolts of electricity shooting up your spine. Feeling the thick meaty penis spreading you open was such a relief as you moved closer to that elusive climax that you so badly needed.
Once two thirds of his dick was firmly inside you, Harry continued with the proceedings as he began slowly thrusting in and out of your slick, eager folds. The rubbing and grinding of the various notches and bumps made you neigh in pleasure as Vicky continued to lovingly cradle your head in her arms.
After a couple of minutes the two of you had settled into a steady mating tempo. You now rocked in time with Harry’s thrusts as he brutally rammed into your gaping pussy again and again. Wet sloppy squelches now accompanied Harry’s thrusts as your excessive lubrication was compressed and forced out of you by the advancing cock.
As you sensed that it would all be over soon, you looked over Vicky’s shoulder to check that Jessica was alright. She seemed to have recovered somewhat from the shock of being mated as she now watched you with a mouthful of grass in her mouth. She still seemed upset by what was happening to you, but perhaps she too had accepted what the inevitable outcome would be.
With Jessica seemingly understanding your choice, you now felt reassured that she would not hate you for what you were about to do.
With a series of loud, forceful whinnies, you took matters into your own hands as you pushed back hard against Harry’s cock, allowing it to sink all the way into you as you felt the skin of his sheath kiss your vagina’s stretched outer walls. Now you could also feel the stallion’s two enormous testicles as they slammed into your ass over and over again.
You knew this was it. You were about to become a horse forever, but in that moment you were at peace as you finally accepted your fate.
With one almighty cry of passion you finally reached the precipice as you came hard around Harry’s pumping shaft. A wave of rich feminie arousal coated the stallion’s length as your pussy trembled and convulsed after finally getting the release it was after.
With your head now in the clouds, you waited in eager anticipation for your reward as Harry shoved his flaring dick right up against your cervix. You found it oddly ironic that you saw this as a ‘reward’ after all the times Vicky had used the term during your training, but you were soon distracted from this thought as you felt the first rope of Harry’s semen splattering deep inside your fertile womb.
Vicky continued to stroke your nose as you jerked in time with the blasts of cum that were being fired into you. You now felt warm and cozy inside as the creamy fluids quickly filled you up and started running down your hind legs. And as you basked in the afterglow of your amazing orgasm you truly began to embrace the now-permanent changes.
You pushed your former humanity, including your own name to the back of your mind as you now accepted that you were Princess. And as you felt Harry’s seed spilling out of your stretched equine cunt you couldn’t deny that there was now nothing remotely masculine about you. You were now a female horse. You were Princess; the Stable’s newest broodmare.
After accepting your new persona, you now waited patiently for the mating to wind down. This took a minute or so as Harry kept his penis in place, just to make pregnancy as certain as possible. Then, once the last watery dribbles of cum were safely inside you, he finally withdrew. He slipped out of you with a wet *pop* after which a warm gush of excess sexual fluids flooded out and splattered on to the floor.
With his job now done, Harry obediently returned to Vicky’s side as she continued to gently stroke your nose and face. “Good work Harry, another healthy broodmare for the Stables. Doesn’t she look happy!? So much better now that she’s a horse, wouldn’t you say so?” Harry snorted in agreement as you stood motionless, with the stallion’s seed continuing to pool inside you.
“Right then, I think it’s about time that we put you two little madams back where you belong. Then, perhaps you can start making amends for your poor behaviour.” Hearing this should have made you worried, but in your tired, hazy state you simply neighed dumbly and allowed Vicky to fit you with a bridle and rope.
And before you knew it, you and Jessica were both following Vicky and Harry back towards the Stables, ready to begin your new lives as prized exhibits of the Zoo…
