Every day for two weeks she performed the same routine, in the morning Sapphire was fastened on the treadmill, this consisted of a continuous belt, on which she had to run in a stationary position and in the afternoon she was on the lunge, until Honor announced that she was ready for the next stage of her training.

This part was to get Sapphire ready for racing. She was taken down to the bottom end of the stable and her trainer came out to inspect her. The trainer whose name was Claire harnessed Sapphire to a sulky and made her run around the track. The track was a bit like an athletics track only wider. Sapphire was first driven round alone, her driver, Michael and Claire taking particular note of how she performed.

After about six laps Sapphire was tethered to the fence and allowed to rest; one of the grooms giving her some water. Meanwhile Michael and Claire were in conference, both agreeing that Sapphire had quite a bit of potential. The next four weeks were quite intensive with Sapphire being tested for speed and endurance; her speed was fine but she needed to get a bit more stamina so she was put back on the treadmill. She started off being given half an hour with a rest of ten minutes gradually working up to one hour, non-stop before being given a rest. At the end of the four weeks Honor was told that Sapphire was ready for racing.

Sapphire was entered for her first public race one week later. She, of course, had no knowledge of what was to happen to her.

The day of the race meeting arrived and Sapphire was hosed down, oiled and dressed in her best harness; she sensed that today was to be special but still had no idea why. She was taken into the courtyard where a horse trailer was waiting, and loaded onto it. Already inside were three other mares. Once Sapphire was firmly tethered the grooms shut the back up and the engine was started and away they went. Sapphire looked at the other mares; they seemed unperturbed, in fact, quite happy, so she settled down herself and waited to see what was to happen.

When they reached their destination and were off loaded from the horse trailer Sapphire was dismayed to see hundreds, if not thousands of people, all milling around and looking at her. She tried to run away but she had two grooms holding her, she was blushing a deep scarlet by now. She had got used to being naked in front of the staff at the stables, but had not been out in public like this before. The other mares were standing quite still and letting the public pet and fondle them. It took the grooms a little while to settle Sapphire but eventually they succeeded and began to walk her round the stadium until she had calmed down sufficiently to enable them to get her standing still for the punters to look at, but not calm enough for them to pet her.

There was still a couple of hours to go before the first race, so the grooms took Sapphire into the parade ring and walked her round. The longer she was out in public the easier it became for Sapphire and after a while she even let people pet her. When it was time her groom took her to the starting line and her driver, Michael made a fuss of her before getting into the sulky. Claire her trainer was also there. There hadn’t been any race plan as this was Sapphire’s first competitive race they were just going to see how she coped.

The starter called them to the line and grooms and trainers left the area. Michael was talking softly to Sapphire, telling her to take it easy nobody was expecting miracles, as it was her first race. He noticed that she was quite calm and when the flag went down she set off at a steady pace just behind the leaders. As the race went on it was clear that there were only two horses in it, Sapphire and a filly called Columbine. With just over one lap to go Columbine made a spurt that took Michael by surprise and within seconds the filly was 25 metres ahead. He shook Sapphire’s reins, asking for more speed, which she responded, and soon Sapphire was clawing back the distance between her and Columbine. With just 100 metres to go, Sapphire was 10 metres behind. Michael thought she had lost the race but was delighted with her performance and to come second was no mean feat. He was brought back from his reverie when he noticed that the gap was getting smaller, with less than 5 metres to go Sapphire and Columbine were neck and neck. At the line it was impossible to separate them.

He gradually pulled Sapphire to a stop and while he was doing so, he glanced at the other driver, she was laughing and patting her filly. Michael called out to see if she knew who had won but she had no more idea than he did.

As Michael was taking Sapphire back to Claire and her groom he heard the loud speakers proclaiming that it was a photo finish and the judges would give the verdict later.

It was almost time for the next race before the judges’ verdict was announced; First, Sapphire; Second, Columbine; Third Firefly. The distances were, half a breast and four lengths. Sapphire was so pleased with the result that she forgot to blush when it was announced that she had won by half a breast. That wasn’t the end for her though as she was booked to race later that afternoon. A race she won comfortably by three lengths.

Two days after Sapphire’s trip to the races she was harnessed in the usual way with one exception, this time she was fitted with blinkers. She tried to indicate to her groom that she wanted to know why but either the groom didn’t understand her or was deliberately ignoring her.

Once the harnessing was completed Sapphire was taken outside and hitched to a dogcart, which was normally used to ferry various items around the stables. When she was hitched up Sapphire’s groom waited with her and eventually Sapphire felt the weight shift, indicating that someone had climbed aboard. Sapphire’s groom gave her a sharp slap on the rump and told her to walk on.

Sapphire was taken out through the stable gates and along the road that led to the beach, where the animals were taken occasionally to play on the sand and in the water. After a while they came to a small cabin just off the side of the road and her driver pulled her up.

The driver unhitched Sapphire, who still had no idea who it was, and led her to a fence where he tethered her. As Sapphire couldn’t see what was happening she was getting agitated, she was turning her face as far as she could in either direction but her driver was out of her sight. She heard rustling and movement behind her and suddenly she felt hands on her breasts and, horrors, an erect penis rubbing her inner thighs. She would have screamed if she hadn’t been bitted. It was then that her driver showed himself. It was her darling Robert. He was kissing her, fondling her and in a very short space of time entering her. The first time he took her he only lasted a few minutes before he came and she was disappointed as she needed it to last and last. The second time he brought her to a mind shattering orgasm, so much so that he had to hold her up to prevent her from hurting herself by falling.

After they had rested, Robert told her that the business was in good stead and that the money Honor had paid had cleared all their debts. He told her that they had got some new contracts and that they were even able to employ a sales rep. Sapphire wanted very much to talk to him but Robert told her that he had agreed with Honor to keep her bitted so that she couldn’t talk. Sapphire had no alternative but to comply with Honor’s instructions.

It was a very jaunty Sapphire that trotted back to the stables later that afternoon.

The weeks went by and Sapphire got a new groom, John having gone into training. The new groom’s name was Jenny. She and Sapphire hit it off straight away. Jenny was very talkative and kept up a running commentary while she was seeing to Sapphire.

Once a week Jenny would masturbate Sapphire with a vibrator, she explained that while the resident stallions could service the other mares, Sapphire was barred from that activity, although Jenny didn’t know why. Jenny also told Sapphire that sometimes prize stallions would be brought in to cover a mare if she was to be foaled and when that happened it was quite a big thing with guests as well as the owners of the relative mare and stallion being invited to view the encounter. Sapphire shuddered to think what it would be like to be watched having sex but she really looked forward to her sessions with Jenny, as Robert’s appearances were few and far between. Although when he did turn up he left her well satisfied.

The weeks turned into months and Sapphire was raced regularly, winning every race she was entered for. She was so used to being naked in public that it no longer bothered her. In fact, she revelled in the adulation that came with winning.

Sapphire had already become the National Champion of Britain and arrangements were made for her to run head to head with the National Champion of Europe to determine who was the Supreme Champion. Sapphire won that race also.

Finally, Sapphire’s last week came round. She greeted the fact with excitement and not a little sorrow; she had loved almost every minute as a pony girl, but it would be great to be back with Robert. She thought their sex life would be a lot spicier now.

On her last morning, Jenny got Sapphire ready in her best harness; her hair was shining with health, her body oiled until it glistened. Sapphire was trembling with nervous excitement. She walked round and round the cobbled courtyard. She saw three mares being loaded into the horse trailer and looked quizzically at Jenny who told her that they were being taken to the sale yard for auction.

Out of the corner of her eye Sapphire noticed that Honor and Robert were coming into the yard. Both were beaming. Honor came over, kissed her on the nose and said, ‘Well today should have been the day for your release but I’m afraid I have some bad news for you Sapphire, you are not going to be released today, in fact you are never going to be released. You will be going to auction with the other mares.’

Sapphire felt as though she had been punched in the stomach, and because she was still bitted, she couldn’t articulate what she wanted to say. Tears were running down her face, she looked at Robert for support but he shook his head. Why? Thought Sapphire, what had she done to deserve this?

It was a little while before she realised that Robert was speaking; he told her that the business was never in any trouble; she was told that as a ruse to get her to become a pony girl. He told Sapphire that he had been having an affair with Honor right from their wedding day. In fact he told her, we had sex twice on the day itself, once before the ceremony and once during the reception. He grinned delightedly, ‘You see the beauty of this scheme of ours, don’t you?’ ‘I could, of course have divorced you but then you would have been entitled half of everything. This way, I get to keep it all and in a couple of years I can file for divorce on the grounds of desertion and you won’t be in any position to contest it, so no payout for you.’

Honor took over from Robert. ‘Don’t be sad, sweetie, I’m sure you’ll be well looked after by whoever buys you. And you have done us proud. You have repaid the outlay on your training, equipment and food by at least ten-fold. That’s not including the money we’ve won by betting on you. And the icing on the cake will be your sale fee.”

She gave the nod to Jenny to load Sapphire onto the trailer. Sapphire went berserk she kicked out at Jenny who was nearest, missing her by a fraction. She pulled at her reins, whinnied and generally fought them all. It was to no avail, there were too many, the other grooms joined in and with Honor giving some well aimed cuts to Sapphire’s rump with her riding crop Sapphire was soon strapped in the trailer for transport to the sale yard.

During the short journey Sapphire’s emotions went from deep depression to determination that they, Honor and Robert, wouldn’t win. She hatched a plan that would see her being docile while she was being taken to the sale ring, then, once in the ring she would go berserk again. That way she reasoned, she would avoid another beating with a riding crop and no one would want to buy her if she was that ill behaved. With those thoughts she awaited her fate.

Sapphire was the very model of good behaviour when they arrived at the yard. She allowed Jenny to walk her down the ramp and into the viewing gallery. She waited patiently for an attendant to take her into the ring and even behaved herself at the entrance while the auctioneer gave her details to the bidders.

It was there that Sapphire’s plans fell down, listening to the auctioneer extolling her virtues; Ladies and Gentlemen, it is indeed and honour and a pleasure to offer this very fine beast for sale. Sapphire stands 13 hands high and her measurements are, bust 34”, waist, 24” and hips 34”. Her photograph in the catalogue does not do her justice; she is without doubt one of the most beautiful animals I have seen in all my years working here. Sapphire’s record speaks for itself, as she has never been beaten in any competitive race. She truly is a worthy Champion. Something happened when Sapphire was led in that amazed everyone connected to the sale, people stood and clapped.
