She took this autonomy to good use and after insisting the barn worker to clear thoroughly the stall belonging to Billy and put in it clean straw, she had an added plan of visiting him for a much longer duration of frolicking. Billy seemed to notice his stall as cleaned the concrete floor even hosed with hot scalding water to remove soiling and fully disinfect it from his natural scent.

 

When after Karla had her dinner and walked out to the barn, she planning to be play with Billy, she was delighted to find the stall clean enough for her to decide, she might stay there the entire night.

Play and massaging did what it had before, Billy letting hang his long maleness, giving her a thrill at touching and stroking his male meat. Unlike at other times, this time she came prepared with a bottle of hand lotion, with plans to use it for increasing her stroking to the very erect male organ. This was her plan and not his, for when she first applied the soothing liquid, Billy felt the cool chill of it on his taunt flesh and moved away, keeping his distance from Karla.

Karla followed the pony all around the stall, but he would step away from her, acting as if he had lost all trust in her as a friend.

 

She seeing this as a problem then thought if he were to like her again, he would need to smell her. Therefore, with this new plan she wrestled into the stall two hay bales, and covered them with one of the aged old saddle blankets. Then she removed her jeans and tennis shoes, socks, and finally her silken panties, lying down on the hay bales she spread her legs and gave Billy something she thought he would like.

Likable? Billy took a sniff of the air, his upper lip curled back as he became quite spirited, prancing he advanced toward Karla, she watching him from her helpless vantage point. He danced to her and first put his muzzle to her sensual folds, the sniffing a couple of times and then licked at her what had Karla near to going crazy. The sensual lick to her most sensual self caused a near orgasm of its own and increased the interest of Billy to this a possible mate.

Wide were the eyes of Karla as she lay there stood over by the pony and his four legs pinning in place, His rotundas belly pressing down against her holding her snug to the stiff hay bales. Almost as if he had done this sort of thing before, the stallion pony stood over his mate, he with his might shaft in a fully erect state did then move slowly as the flared head plowed into her. His maleness spread wide her lips and allowed the entering at an easy pace as juices flowed, Karla lay moaning, feeling the hot horse-meat sliding into her going deeper.

When Billy struck bottom and could not advance any deeper into Karla, he began to rock his pelvis, stroking his shaft in and out, driving Karla from one orgasm to the next, until she blacked out.

Awakening, Karla noticed quickly the early morning light coming through a window there in the stall belonging to Billy. Frightened for the reason of someone there discovering her improper playing with Billy, she went to look for her discarded clothing and found not a peace, scrap, or shoe. Looking around, not even Billy was in his stall, his door open and he having gone out, she thought he might have run away.

Finding a pair of work coveralls left there in the barn by one of the men, she donned them on and proceeded to run for the safety of the main house, with plans to take a shower. Coming to the house she discovered the back door as locked, leaving her stranded outside until Jake the supervisor of the other men arrived, he having keys for every lock on the entire farm.

 

Sadly, Karla returned to the barn, thinking then to drag the two hay bales back out of the stall, in hopes of removing all of her degrading play toys. She arriving back at the stall there stood Billy, he seeming elated to see Karla. She tried removing the hay bales but Billy would come and placed both fore hoofs upon them, making the moving of them as impossible.

This aggravated Karla, she getting angry tried verbally yelling at the pony, as if doing so would warn him to keep his distance. This failed too, and as Karla leaned over a bale to get a better hold and block Billy from stepping up on it, he walked over and covered her as he had the night before. Unlike when she was on her back, this time he had her face down and squirming.

Feeling the bumps coming from an excited and fully erect male member belonging to Billy, it bumping her butt, Karla tried harder to squirm free from being under the aroused stallion. Her squirming did just the worst thing, it helped with the slipping down her the coveralls, leaving her with a butt up and a stallion standing behind. Billy took advantage to this, he moved swiftly and nailed Karla, this time he buried his shaft inside her in one massive thrust.

She was scared and her nether lips were dry certainly not in a juiced state, the entry of the huge flared glands into Karla became more painful than she could stand, and she fainted.

This time when she awoke she heard voices, the men had arrived and she was still with Billy. She found she was buried in the straw covering the stall floor. Her stallion lover stud lying partially over her, his still stiffened shaft stuck deep, keeping them both as quite aroused. They continued to lay there for what to Karla, she thought as hours. If she moved, the pony stallion shaft tended to stiffen, it spurting in her more of his semen.

Adding his insult to her injuries, he continued to protect Karla. He in his aroused manner laid there all day, keeping Karla as his, the stallion pony acted as if he had a logical reason for doing what he forced her to accept. It was late when Billy climbed up to stand on all fours, his erect member jellified but still holding a sound grip inside of Karla. She felt his shaft stiffen in her as he lifted her up off the stall floor, suspended on the then stout as flared end of that might pony shaft.

Happy and feeling still horny, Billy walked slowly, he heading for the hay bales still in his stall. He was careful as he helped Karla to slide her body up onto this one bale, her head hanging off the far end put her rump and legs at a perfect angle for the stud to have some added fun. Fun is what began anew, and thrusting, the black shaft slid in and down, this time to the surprise of Karla, he embedded the entire length inside her body.

It was after sundown and the barn and stall lay dark from a moonless night. Billy feeling a need to get a drink dislodged his stout shaft from out of Karla. She by then was limp and laid there, her strength to fight wrung out of every fiber of her body. She moaned from her full day and the many hours of him rutting her constantly. Weak of self, she felt hot and sweaty and removed her soiled blouse and sweaty bra, this had her lying fully naked in his stall.

Slowly Karla regained some will to move and crawling back to a sitting position on the hay bale, she sat there gasping for her breaths, feeling strangely thrilled by her day of wild sex.

Billy having drunk his fill from the five-gallon bucket set into his stall, he munched some grain put in his meal bin and then whinnied at Karla to come, as if she should get a drink too.

Parched too, Karla was willing to get a drink from the bucket Billy drank from, but when she tried to get up and walk that way, she fell forward, finding it as if proper and comfortable for her to walk on all fours. Standing, as would Billy, she on hands and tiptoes in the straw, she thought this silly and tried to laugh. Her laugh was not a human laugh but came out of her as one long drawn out giggling whinny. The sound of this scared Karla, as then she took to looking at her body, seeing there she had sprouted fur.

Sauntering closer to the stall window, Karla let the dim yellow glow of a security light outside show her of what and how much of her had fur. Using her hands to climb up and hold onto the iron bars protecting the window from breakage, Karla saw she was fur from top to bottom, arms, legs, and seeing that her feet were longer and her toes had become as cute hoofs.

Crying from fear, Karla sank down hunched on her legs, as from out of the dark stall Billy came to give her some comfort. Snuffling at her hair, the pony stallion tried to quell her worst fears. The obvious fear being after a night and daytime of being so horny and mated by the stallion, he had caused to her a changing into becoming a pony too.

Not wanting his touch or affections, Karla grabbed hold the iron bars once more, she stood looking out the dirty window, felt a feeling as of her still changing legs and the new hind hoofs.

Billy came close and gave an affectionate lick to where her nether lips had traveled. His touch made her shiver, the goose pimples tickling in her groin. There the soft skin of an equine mare udder, the feeling trailing off the equally aroused ends of two sensual teats. Feeling this and reaching a free hand to touch it, Karla tried to scream but whinnied harshly. Scared as angry with her pony lover, she began high-stepping a in place prancing as she stood there. The weird want to prance and feel then a new host of different feelings, one that made her scared more was from the touch to her tail swishing over a very sensitive place.

Wishing she could plead that this not be true, Karla unable to speak English found her mutterings as understood by Billy. He began to say to her not in English but in sounds, and seemingly similar then to words, they conversed. Karla met then a relative, Billy a cousin to her father, he had many years before insulted a woman who was a witch. Witches live long lifetimes, some even as alive for centuries. As he told her of how since she made of him to be a pony, he had as well a much extended life while being quite like a real pony. Most of his life was of work and drudgery, but or when allowed to mate a mare he discovered arousing fun times, given to and having some stallion style fun. The most recent fun feelings came with coming to feel a sense of love for Karla.

Billy had learned much during his years about the curse done to his life. His maleness was a key to the curse and could by him choosing a human to mate, he could bring to an end his bestial lifestyle. He told Karla how by his protecting her when the second time they mated, and if then on that night she were to allow him to mate with her a third time, she would fully join him, they both as ponies, as if together for many years, or decades to come!

She had then a choice, but one not without its problems. As Billy stood there telling Karla about living pony like, there seated on the stall door sat a red eyed dark figure of a little man.

Suddenly to a scare of both pony and his dear Karla, a voice piped up and spoke to them in their equine language. He greeted Billy and then turned to give a jagged toothed smile at Karla, informing her that she had gone too far to turn back.

 

Billy wanted to argue but the little devil stopped him, as it said to Karla about her having changed as far as she had, her ceasing desire of stallion lovemaking would force her to remain a pony-taur. Being partially changed, to regain her lost humanity of form, he said she must be that way for three months before she would then change back to being human.

 

He seeing her horror at his statement, he then smiled, and added one more proviso to her ordeal. If she after having mated twice with Billy, became pregnant, she would change completely, as well quite permanent then being a pony mare.

 

The little devil posed then another option, one he said would be the easier. Suggesting to Karla that she mate the third time with Billy. She looked at Billy and he to her, their mutual feelings from the wild thrill alive in each. She thought of wants and lust, knowing and as much willing to mate again for another glorious night. If she did, and they bred the third time it would be come morning when the men arrived to do their chores, they would find in the stall with Billy a pretty pony mare.

Karla pondering her passions, heard an excited Billy dropping a butt-load, she quickly decided she did not want to become a pony mare. She ached where he had with his massive male tool thrilled her, she liked the feelings taunting at her, but lingering still was the thought of living as do animals, she liked being human better.

Early in the morning hours Karla said her good bye to Billy. He was devasted, as tried to disuade Karla to stay so that he too might, in time win his freedom from the curse. He had not said as to all of what he hoped, before she left him and ran off toward the far woods and the river delta, thinking there to hide there for three months.

As she ran, she did so mostly on all fours, her body still changing from all the cursed semen it had accepted.

 

In coming days and weeks with Karla missed and she never returning home, there was a search but, nothing did they ever find. She saw them coming and hid, learning to use her instincts to the max, Karla wandered, moving up river and found there a farm with many horses and ponies.

Changed more as of form to look like a pony mare, Karla felt closer to the animals than they to her, accept for one elderly stud. He kept trying to jump and hump her as she stood in the pasture, learning how and having to graze to eat to live. Two months into her time of seclusion, feeling the pangs from pony-period wanting of sexual pleasures, she struggled with deep passions. The elderly stallion was not like Billy, he was born to being a pony and often came to her and she felt relief when he would mount and mate.

 

Her wish of dearly wanting to be again human was in conflict with her almost daily pleasuring done by the old stud. One morning when eying a look at her reflection in the watering pond, Karla noted she was getting plumper. Fearful of what this meant to her, those womanly contours not returning, she thinking this was from how well she had learned to graze, had done it with the herd often all night.

 

Grazing became a thing of mindlessness, her brain slipping into a lulled state of ignoring her great hope of being again fully human, she caught her thoughts liking as wishing she could remain as is a pony mare.

 

So, when one afternoon she felt the elder stud land on her rump, he straddled her and moved his bulk self forward over her back, she was reminded of the little devil suggesting she let the third time happen.

In actuality it had happened long hence, and many times more since, as this time he came on rough, like would an old male pony. Her quick thrill she then felt held not the worth as it had cost to her a price she had to pay. As after that her need for mating ceased and another pregnant mare became a member of the herd. To Karla, her living there mingling with the others like her, she continued mating with other stallions. She dropped her foals and let them suckle. Her mind began to fade, and not until she went as a 4-H pony to the fair did she meet a beautiful woman.

 

This woman was the witch that had so cursed Billy. The witch could see the past of this mare and made her an offer, such a deal that even a dehumanized but sensually drunk pony mind could agree to the proposal.

Accordingly, she had to act alluring, coming on to a young male person, as had Billy done to and for her. If she could lure him to mate with her three times, then he would change into a pony and she could become again human; or so the witch implied.
