The woman promptly continued with her sick plans. Quickly she dipped her fingers into a small puddle of sticky horse jizz on the floor. She then began rubbing the stuff all over Mark’s privates. Then, to his horror, she proceeded to push down firmly on his cockhead with the palm of her hand. As she did this the man’s shaft and balls seemed to disappear within his body. Soon, in place of his proud member, Mark now sported his very own vagina.
Mark didn’t have time to react as he was forced on to his hands and knees, and swiftly violated as the woman thrust her fingers inside the virgin opening. Just as with the brown horse things started to change.
First Mark’s backside began to enlarge. He felt his bones creak as his rib-cage expanded and his limbs readjusted. Black hairs also started appearing over his body as he continued to swell at an alarming rate. Meanwhile the female attendant kept thrusting rigorously as she worked on the next addition to her stable.
George was whinnying loudly, but it was hard to deduce whether this was due to horror or lust. He had been through this process himself, and his human side increasingly began to despair as he thought about all he had lost, namely his humanity and femininity. And yet his horse mind thought about what had been gained; an enormous member, a powerful body, and hopefully soon a new Mare to mate with. With these thoughts the horse’s member began to harden again in anticipation.
Meanwhile, the woman kept thrusting in and out rapidly with loud squelching noises. By now Mark, now a she, almost resembled a full mare. Her uniform had been utterly shredded by her enlarged horse belly and arse. A black-haired tail had also sprouted from her backside, while her hair had lengthened and darkened as it became a mane. All that was really left was her head and neck which just had some growing to do.
It was now that the fingers stopped. They had done their job since Mark now had a body which could accommodate the virile stallion. The transforming man now sported a fine mare’s pussy, which was now leaking pungent fluids down her back legs. She was ready.
With that George was slowly guided towards Mark's backside. Mark tried to suppress her instincts, but the ordeal had made her too weak. Slowly the mare-to-be moved her tail to the side and spread her legs slightly, inviting the stallion in.
In a similarly desperate situation George tried to hold back one last time. He yanked as hard as he could, sending one attendant to the floor, but the others held him fast until back-up arrived. This was the final straw. Georgina’s hopes had now been completely crushed. He saw no escape from this situation and so he finally accepted his fate by roughly mounting Mark from behind.
“NO! Mark tried to scream as she felt something poking around her rear-end. “NO. NEEE. NEEEEIGH. NEIGH NEIGH!” Mark whinnied in alarm as her voice box was consumed by the transformation. Then George finally hit his target and nudged his mushroom-shaped cockhead past Mark’s puffy nether lips. Mark tried to scream out but could only produce shrill whinnies as her transformation continued. The dark fur had spread all over her face by now and her neck was now the right size for her head to finish changing. Sure enough, her ears became pointed and moved up her head, while the rest of her face stretched out into a horse muzzle. As George continued to stuff his dick deeper and deeper inside the former policeman, the pair became more and more aroused.
Mark’s human consciousness was still hanging in there, but it was rapidly fading away. She tried to shake the big brown stallion off her back but he was so heavy and she was so tired. She let out exhausted whinnies as she felt her ordeal, and her human life, drawing to a close. She wanted her human mind to fade away, but that primal instinct for survival would not let her die. She would have to see this through.
By now George was as deep as he could get inside the moist cavern. He had started thrusting purposefully as his now complete horse-self wanted to finish what he’d started. The barn now echoed with all sorts of noises; from the clapping and jeering of the attendants, to the loud whinnies of both horses, as well as the wet squishing sounds coming from Mark’s pussy.
Mark could feel the end was nigh. By now her face had finished its change: she was now a complete mare. She could feel the rock hard member trembling deep inside her. She knew there was nothing she could do but wait. Luckily, she didn’t have to wait long as George finally exploded inside her. Wave after wave of sperm blew out of the brown horse’s member as he emptied his giant balls into the mare below him. The mare came soon after, sending juices spurting out of her strained pussy.
The attendants promptly withdrew the stallion’s giant organ as a mixture of semen and pussy juice flooded out in its wake. George’s front hooves clopped to the floor and the stallion was now satisfied. Mark the mare was also feeling relieved. Finally that pesky human consciousness had been beaten and her proper purpose had been enforced. She wasn’t some dumb human. She was a powerful and sexy mare. And she was complete.
With that the action died down. Most of the attendants left to do other things, while the two horses began cleaning up the mess they had made. As they lapped up a large puddle of juices together, the female approached them.
“There we are. I’m glad you enjoyed that so much. You two should prove very useful for my business.” She then spoke directly to Mark. “I see you kept fighting to the last Mark, and I can respect that, but in the end where did it really get you?” As if to emphasise the point the black horse reached her long neck forward to clean up some little globs of cum that still dangled from George’s receding member. “If you’re as dutiful to me as you were as a human I think you will be a valuable pet. Mark neighed in approval as the woman stroked her behind the ears. “We also need a new name for you. Hmm….I think ‘Mary’ is perfect as it’s not too different to your old name.” Again the big horse whinnied her approval. “Good.”
And with that George and Mary were taken to their new home while the woman went to tend to her other guests.
