Prince’s hooves thudded to the ground as he dismounted, exiting his mate’s slick folds with a wet *pop*. The freshly mated couple felt deeply satisfied after fulfilling their primal urges.
Princess loved the feeling of being filled up with her mate’s sticky cum. She was relieved that the torturous heat in her loins had dissipated. Now she was already looking forward to having her first foal, having deduced from the sheer volume of semen inside her that she was now pregnant.
Of course, what remained of Princess’ human consciousness felt utterly disgusted. But being mated with as a mare had dealt her surviving humanity a major blow. It was becoming harder to tell that Princess had once been human, let alone male, as the mare instincts now exercised almost total control of her body.
These instincts now told the mare that she was famished after her intense mating session. Soon she was wolfing down the tasty hay which hung in the corner of her stall, blissfully indifferent to any pesky human concerns which faintly echoed in her mind.
However, as Princess merrily munched away at the delicious food, the other two horses did not share in her relief. Both still had their own urges to fulfil.
Jenny had never stopped trying to get the stallion’s attention. By now her back legs were soaked as pungent juices continued to ooze out of her wet folds. This produced wet squelching sounds as her clit continued to wink rhythmically. She had her tail raised and her legs braced, clearly anticipating some action.
As for Prince, he was happy to help her out. Although still breathing heavily from his first rigorous mating session, the mighty stallion was already limbering up for round two. His cock had never had a chance to soften as it dripped a mixture of stallion and mare juices to the stall floor.
Regrettably their preparations were in vain.
Just as Prince reared up to mount his second mare, he was startled as several ropes were skilfully wrapped around his neck. He snorted and flailed about in frustration as a group of attendants forcefully dragged him away from his prize. He struggled, but he had yet to recover from his vigorous love-making. Sadly, despite his defiance, Prince was eventually led away, out of Jenny’s sight.
Jenny whinnied in dismay as her would-be mate was taken away. The two horses continued to call out to each other in desperation until Prince’s cries faded away.
“Handsome specimen, isn’t he doc?” One attendant strode up to the needy mare as she mourned the stallion’s departure. “I believe congratulations are in order! It seems that your formula is a resounding success. You always said you wanted to leave behind a legacy with your work. And now the world has something to remember you by; well, that and any foals you happen to produce!”
Jenny snorted as the attendants around her chuckled. How could they be this cruel? Already she was being treated as a dumb animal. Internally Jenkins was still clinging on, although it was difficult to overcome the female instincts surging through her new body. In fact Jenkins had designed the formula to induce immediate heat in any newly-converted mares. She knew it would never abate until she was mated with. It had seemed like such a good idea at the time, but now she was deeply regretting it.
The attendant smiled as the wet squishing sounds continued to emanate from Jenny’s hindquarters. “Quite a horny little mare, aren’t we?” the man teased as he inspected between his former colleague’s legs. He smiled as he watched her vagina open and close; catching glimpses of the clit which used to be the doctor’s penis as it flashed in and out between her engorged pussy lips.
“How about a deal ‘Jenny.’ Behave yourself and we’ll take that discomfort away from you in an instant. But resist and you’ll suffer like this for a very, VERY, long time.”
The question caused her to hesitate. On the one hand, her human mind fought to resist. He was Jenkins, not Jenny, and he was a man, not some stupid mare! Sadly, even this side of Jenkins’ fragmented mind couldn’t ignore the burning sensations deep within his female body. He knew that a stallion’s cock would take the pain away. The burning was getting more powerful by the minute, and currently there was only one available way to stop it.
Soon, Jenny’s mind was made up. She bowed her head and decided, for the moment at least, to obey her new master. “Wise choice doc” the man responded as he smiled.
Meanwhile the other attendants smirked as Jenny was led away; already knowing exactly what was in store for their latest victim.
