“Now girls, tend to our guests.” The woman’s fresh orders resonated within your brain. Somewhere at the back of your mind you knew that what you were doing was wrong. And yet you obeyed. You started to suck reluctantly on the head of the officer’s exposed cock.
“Princess where are your manners?” the woman teased. “Start with the balls” she said as she delivered another hard slap to your giant horse arse. As if to apologise you quickly began sucking on the officer’s testicles, although they were so small that you found it hard to control your ministrations. Thankfully, your worries diminished as they started to grow inside your mouth. “Much better” you thought “much more manageable. Hang on… what the heck am I thinking? This is sick.”
You sensed Mark’s alarm as his balls grew to the size of tennis balls, whilst also getting hairier and much tastier. “No that’s so wrong. Snap out it!” your human mind tried to scream, and yet you kept going.
“Now the rest dear.” You did as she said. After lapping at his member to get it hard you engulfed the entire length within your massive mouth. You bobbed you head and swirled your tongue around his shaft while it nestled inside your mouth. Then gradually you felt your face being pushed away as the member grew to more equine proportions. You could see from the pained expression on his face that he didn’t want any of this. And still you kept bobbing and sucking. And then it happened. As you felt his cockhead morph into a mushroom shape he finally came hard inside your mouth. Your muzzle was flooded as what seemed like gallons of creamy horse cum exploded from his tip.
“That’s a girl” said the woman. “Looks like you enjoyed that a lot. Now show us your pretty face.” As commanded you turned around. The woman giggled as she saw just how much cum had been dumped into your mouth. Even now, long sticky strands of the stuff hung down from all corners your mouth.
“Carry on Princess.”
Instinctively you slurped up as much of the tasty semen as you could using your long tongue and then proceeded to carefully clop backwards towards the unfortunate officer. Then suddenly you felt his own tongue glide up and down your drenched mare’s pussy. As you feared your pungent juices had done their job. Mark’s mind was now clouded with lust as he continued licking.
After collecting as much gooey liquid as he could from your rear-end, he proceeded to put his mouth over you puffy vagina and started to slurp up the fluids that poured out; like some high-powered vacuum cleaner. As he drank, Mark’s body seemed to change to match his member. It began with the fusion of his fingers and toes to form hooves. Then gradually, millions of black hairs grew out all over his body. His legs and arms also began to re-orientate to become horse-like.
Meanwhile your resistance was weakening. Your body was on fire. The more juice Mark drank, the more you seemed to release. You increasingly wanted the heat within you to be quenched, and you knew only one thing could do that. And in order for Mark to be able to use it, you would have to change him more. You closed your horse eyes and tried to stop yourself. You couldn't allow yourself to doom the poor man.
Seemingly in response your body, now in open revolt against your mind, betrayed you as you fired a warm jet of juice into Mark's waiting mouth. Your mare body clearly wanted the process to be complete. “Dammit! Must...keep...control.” You strained against your body's actions wanting desperately for this to stop.
By now Mark was almost a full horse. His backside and belly had filled out to stallion proportions. He also sported a beautiful black tail and mane. His head was almost done as well. Even now you could feel his features grow as the involuntary spurt of fluid did it’s job. Sure enough, when Mark finally pulled his muzzle back from between your legs you looked back to see a big black stallion in place of the officer.
“Bravo. Bravo” the woman applauded. “You’re both doing so well. Just one final push and you’re done. Mark, come and take the Princess!”
Suddenly, you felt a great weight on your back as Mark the stallion mounted you from behind, clearly intoxicated by your sweet aroma. “No! Not like this…” you exclaimed in the form of shrill whinnies. And yet, your body carried on without your permission. To encourage Mark to take the plunge your tail moved aside and you spread your hind legs slightly.
Mark needed no more encouragement. He slowly guided his mushroom-shaped head towards your twitching vagina. Then you felt the large tip stretching your pussy. “NO! NOOOOO! NEE.. NEEEEEIGH. NEIGH!” This was it. The mental dam in your mind had been breached. Your exclamations turned into horrified whinnies as the last of your human mind began to fade away.
Mark shuffled about on top of you as he gradually slipped his giant dick deeper within you, inch by inch. His advance was virtually without resistance thanks to the sheer volume of lubrication that you had manufactured back there. However, Mark was eventually halted when his hairy horse balls made contact with your backside.
Every inch that was pushed inside helped to destroy you human self, bit by bit. The final straw was when his tip finally touched your uterus and his thrusting began. You neighed lustfully as Mark pushed his hips backwards and forwards, making his giant tool piston in and out, in and out. And now, with your human-self utterly destroyed, your mare mind powerfully re-asserted itself. Now, instead of horror you felt pure bliss. The way his member stretched you to the limit gave you such a good feeling.
“Yes! Yes! Take me! Please!” Your thoughts were expressed as you whinnied louder and louder as Mark’s tempo quickened. This motion was accompanied by wet squelching sounds as his precum mixed with your own fluids. This, plus the increasingly loud and frequent slapping sounds of his massive balls on your backside, told you he was nearly done.
Your new instincts were correct. You felt a sudden surge of warmth deep inside your pussy as Mark let out an almighty whinny and came explosively inside you. His warm sperm poured in to you, completely filling you up to the brim. This immediately sent you over the edge, as you also came powerfully and neighed at the top of your lungs.
Both of you nearly collapsed while breathing heavily, clearly spent. The big black stallion flopped over your back and you struggled to stay upright. Thankfully, some nearby attendants extracted Mark from your rear-end. You neighed gently as you felt his cockhead stretch you one last time on the way out, followed by a cascade of sticky sperm and juice.
The woman then came back into view. “Well done Princess. Look at you! I knew you’d come round to my side.” She sauntered round to the big horse behind you. “There you are officer. Guess your investigation was a success. After all, you now know what happened to those missing people, don't you boy.” The black horse neighed in protest, which only made the woman laugh. “Guess you’re our first police horse.” The attendants around you laughed. Mark hung his lead low in shame.
With that, the woman left and told the other attendants to take you both back to the stables. You went without resistance. You are a good horse after all.
