Mrs King watched eagerly as Prince moved closer to his prize. Jenkins was visibly shivering in excitement as her pussy continued to wink invitingly; her arousal was plain to see as hot sticky juices dripped out of her new organ and ran down her hind legs.
The stallion snorted as he stared at the mare’s large sexy ass for a second. Then, not wanting to disappoint his new mate, Prince shoved his head beneath her tail as his tongue pushed out towards her.
Jenkins whinnied out in delight when she felt the stallion’s broad tongue gliding over her dark puffy sex as it continued to open and close rhythmically. The intense feelings coming from her sensitive new organ sent jolts of pleasure shooting through her body.
“That’s it boy,” Mrs King piped up from nearby, “show this mare what her new body can feel like.” After seeing Prince and Jenkins starting to get to know each other intimately, she slowly sauntered over to the two dapple grey mares as they too watched the show, albeit with envy rather than happiness.
“There, there my dear,” she said as she looked into Georgina’s eyes whilst stroking her nose, “don’t feel jealous of her. Soon you will be beneath Prince again. You should be supportive of your new herd-mate, after all she is just a horny mare in heat, just like you!” Mrs King smiled as the faintest hint of human intelligence flickered in the horse’s dull eyes as the former policewoman seemed to understand her new role in life.
Mrs King then turned to Marcia as she too watched Prince and Jenkins hitting it off.
“And how’s my favourite girl doing?” King said with a mocking smile. The mare just snorted in need, wanting to feel the stallion’s cock inside her again. “Now, now be patient. Prince will be all yours again before too long.” As she spoke she lightly traced her hand over Marcia’s body, starting at the horse’s neck and finishing at her firm rump. Mrs King couldn’t help casting her gaze between the former-man’s legs, just to see how much Officer Mark was now enjoying being Marcia the horny broodmare.
Mrs King soon had the answer as the strong scent of breeding instantly filled her nostrils. The extent of Marcia and Prince’s passion was staggeringly vivid and plain to see. Everything between Marcia’s legs was now stained dark with various juices. Strands of fluid ran over her ass, udder and hind legs as globs of stickiness congealed in her fur. The mare’s vagina was also a mess. Thick creamy cum was spilling out of her well-coated passage as she continued to wink in need. This potent jizz only added to the cocktail of fluids that now dripped down towards the floor, forming a small puddle beneath her.
Mrs King patted Marcia’s ass in satisfaction before she returned to watch Dr Jenkins fully succumb to her new urges.
By this stage the horny chestnut mare was whinnying wildly as Prince’s tongue now stuffed itself into her vagina. The feeling of being spread open for the first time and having her inner walls teased sent waves of indescribable pleasure crashing over her. The sensations would occasionally spike whenever the stallion found her hyper-sensitive equine clitoris. Her whole body shuddered in glee whenever this happened as the anticipation started to become too great to bear.
Having decided that she now wanted more, Jenkins clopped forward a few paces. Prince looked at her in confusion as his tongue slipped out of her. However, it soon became clear what the mare wanted as she looked back at him seductively; her legs now spread and her tail hiked up out of the way of her winking pussy.
“Go on big boy,” Mrs King encouraged as she patted Prince’s flank, “fuck that bastard into this new body forever and then at least you’ll have had a modicum of revenge.” The woman’s words seemed to spark something inside the poised stallion. He looked at Jenkins’ large inviting ass as he got ready to mount her. He was going to put this mare in her place, he was going to fuck her… hard.
Without any further delay, Prince reared-up and landed on Jenkins’ back with a hard thud. The mare groaned as the stallion shifted his immense weight about on top of her. It didn’t feel uncomfortable though. If anything being in the loving embrace of this large dominant male made her feel safe and reassured. Her instincts told her that this stallion was a worthy specimen: he would make a fine father to her foal.
Prince was eager to satisfy his mate’s wishes as he started prodding urgently with his large stiff penis. The entire mottled length was still wet and dripping from the stallion’s earlier conquests, and he was now determined to add Jenkins to the list.
The chestnut mare waited with baited breath as she felt the tip of Prince’s massive organ poking between her legs, smearing the area with various fluids as it did so. The anticipation was killing her as her fertile body stood, begging to be claimed. Her heart hammered in her chest as she whinnied lustfully to her mate, desperate for him to penetrate her ripe virgin cunt.
Mercifully, after a few more tense moments of searching, Prince did eventually manage to guide the tip of his giant penis into his mate’s slick hole. Jenkins neighed out in relief as she felt her tight pussy being stretched open by the mushroom-shaped tip of Prince’s cock. This was swiftly followed by several inches of the stallion’s thick, meaty shaft which forced their way into the mare’s virgin passage.
Jenkins continued to cry out in lust as Prince steadily walked himself forward, pressing more of his heavenly cock into her. Before long, the mighty stallion loomed above her, the rough skin of his sheath now pressing up against her vaginal entrance as his entire length nestled inside her warm, wet folds.
Mrs King was pleased to see that things were progressing nicely. “Go on stud, show this mare how good her new body can feel!”
Prince was eager to please his mistress and mate as he started working his hips backwards and forwards, causing his dick to begin thrusting in and out of Jenkins’ eager pussy. The young broodmare whinnied loudly as the pleasure radiating from her vagina grew even more intense. The way Prince’s thick shaft caused friction against her clit and stretched her inner walls tightly around it was like nothing she had ever felt previously. She could feel her own lubrication spilling out around the cock’s base as it rammed into her again and again.
After a couple of minutes both horses had settled into a steady rhythm. Jenkins rocked forward and back in time with the stallion’s movements as he pounded her in hard, purposeful strokes. Prince would occasionally grunt loudly above her as he continued to pound her virgin pussy, thus ensuring that she understood her new status as his subservient fucktoy.
It soon became clear that Jenkins had accepted her new position full-heartedly. She bowed her head as she whinnied seductively, letting him know that she was happy to be fucked by him at any time, and receive his precious seed if he deemed her worthy.
Mrs King smiled as she watched the rutting build in intensity and ferocity. Even she was surprised at just how quickly Dr Jenkins had succumbed. Now she was nothing but a slutty broodmare, who was loving getting fucked by the mighty stallion.
Mrs King then looked over as she saw Marcia and Georgina growing agitated. Both were clearly gagging for sex as they flashed their clits and called out desperately in long, lustful moans. Witnessing the potency of Dr Jenkins’ formula was truly staggering. Having animals that could reproduce seemingly without end would revolutionise the operation of the Stables, and the Zoo as a whole. King knew that other facilities around the park had their own variants of Jenkins’ formula, but she wondered whether they were all this potent.
Mrs King continued to theorise about the possibilities of Jenkins’ formula until she sensed that her new broodmare was almost ready to join the stables.
By this stage any hint of restraint or shame had been thrown to the wind. Prince hammered hard into his mate’s snatch in short brutal thrusts that made the tip of his cock pound against her cervix. Meanwhile, Jenkins worked with her mate by forcing her hips backwards over his long hard member, making pleasurable vibrations run along its entire length.
This was accompanied by various loud noises. Wet squelching sounds could be heard after each thrust as various sexual juices were forced together within the tight space that lay deep inside Jenkins’ passage. This also coincided with rhythmic slapping sounds as Prince’s enormous testicles slammed into his mate’s ass again and again.
Soon, it was obvious that both horses were about to reach a crescendo…
Jenkins whinnied loudly as she came hard, sending sticky vaginal juices spurting out between her parted pussy lips. Feeling the mare quivering beneath him as she coated his cock with her fluids was enough to push Prince over the edge as well.
Sensing that he was about to climax, Prince reached forward and bit down hard on his mate’s neck, making sure that she submitted fully to his will and didn’t even think about trying to break free.
But this wasn’t necessary as Jenkins stood placidly beneath him, basking in her orgasm as she waited eagerly to receive her mate’s sticky load.
Jenkins didn’t have to wait for long as Prince shoved his dick forward one last time, pressing his balls right up against her opening as his tip flared deep inside her. Jenkins’ pussy clenched, allowing her to feel every inch of Prince’s shaft as his dick began to shudder.
Jenkins whinnied in delight as the first hot blasts of cum splashed deep inside her channel. Her vaginal passage was instantly flooded as jet after jet erupted into her stuffed orifice. Soon, a sticky mixture of cum and mare juices was spilling down her hind legs as Prince pumped his immense load into her.
“Excellent Prince,” Mrs King announced as the mating ended dramatically, “you have given Dr Jenkins a fresh purpose in life. There’s no going back for her now... not that she seems to mind.”
She paused for a moment as Prince continued to ejaculate into the former doctor. “I think we’ll call you ‘Jen’ from now on,” she said as she walked over to look at the quivering mare, “after all, a beautiful mare with a wonderful cunt like yours is better off with a more feminine name. Wouldn’t you agree?”
‘Jen’ just moaned in a half-reply, still enjoying the thick stallion cock inside her as it continued to erupt.
“Very well Jen,” Mrs King happily announced, “welcome to the Stables!”
With that, Mrs King stepped back to admire her new broodmare, now that her fate had been permanently sealed.
The two horses remained locked together for a few more minutes before Prince was finally satisfied. He slowly removed his long penis, stretching Jen open once more before it slipped out to hang limply beneath him. He then stepped back to admire his mate’s well-bred snatch before finally walking off to catch his breath.
With Jen still in a lustful haze, and the two dapple grey mares begging Prince to fuck them again, Mrs King finally decided to leave them to it. She figured that Prince deserved to have some fun following his unfortunate ‘accident.’ And as for the three mares, she wanted to make sure that they had all fully embraced their new roles as obedient foal factories, who lived only to serve their mate and their mistress.
With the three troublemakers dealt with, Mrs King strutted back towards the entrance to the stable, already excited to meet her next victim...
