Jayne spent two days in the Estancia's well-equipped infirmary recovering from her ordeal at the blacksmith, then emerged to begin first light, then serious, race training. She was given the name Flame, on account of her red hair, and by this she was now known.

Flame soon proved herself an outstanding all-round pony-girl, adept at both racing and dressage. She truly loved her work, and was well treated by Gregor. The wounds in her sex and in her nipples healed quickly, aided by Gregor's careful ministrations and after-care. As soon as her piercings had properly healed, which in truth took almost two weeks, the groom set about enhancing her nipple adornments further. Every few days the thickness of her nipple rings was increased until soon the teats themselves were greatly stretched and enlarged, swelling greedily above and below as if to devour the thick rod which pierced them. There were also exercises with weights and pulleys designed to stretch her nipples further, and each night twin-plated nipple trainers to pull and elongate the firm, rubbery nubs.

Each evening, Gregor would slip the twin circular steel plates of the trainer over Flame's nipple, so that they lodged behind the harness ring. The inner of the twin plates, the one that pressed directly against the wide aureola of the firm breast, was wide and flat, like a large stainless steel washer. The outer plate, the one wich fitted behind the heavy harness ring, had four holes through which were threaded tiny grub-screws, their blunt ends flat against the flat plane of the inner plate. With a tiny watchmaker's screw-driver, the groom turned each screw in turn, opening the distance between the two plates - and, since the outer plate was lodged firmly behind the harness ring through Flame's nipple and the inner plate was pressed flat against the wide, pale aureola crowning the swelling breast, drawing outwards and elongating the rubbery stalk of the nipple itself. Gregor seemed able to judge with exactitude just how much to extend the nipple trainer until Flame's teat was pulled taut to a just tolerable degree of discomfort. Settling the trainer firmly against the base of the nipple and the soft cushion of the breast, he would then fit the other set of plates, drawing out and extending that nipple also, before lightly brushing his hands and finger-tips lightly over the firm breasts and their strange, incongruous additions in the lightest of gently, loving caresses.

Although speech was permitted Flame only in very strictly controlled circumstances, Gregor could speak to her at any time, and talked to her constantly. He explained he wanted to give her the longest, thickest nipples in the Estancia. Far from being horrified, Flame was proud that Gregor thought so much of her and nodded her agreement.

One day, Don Estanio came to see her. Jayne listened as the Don explained that he had discussed her training with Gregor, and that Gregor had asked permission to use special techniques to enlarge Flame's nipples to grossly abnormal size. He went on: 'Because this is something outside the original terms of your contract, I have come to seek your agreement with what it is intended to do to you. Under the terms of your agreement here, you were not to be permanently marked nor harmed, nor was your appearance to be materially altered, other than by the brand on your buttocks which, as you know, will in any case slowly fade despite its being called a "permanent" brand. Normally, the piercings through your nipples would quite quickly close once you stopped wearing your rings: within a couple of months of leaving it would be impossible to notice anything peculiar about them - unless of course you decided yourself to continue wearing some form of body jewelry through them.

'However. If you allow Gregor to proceed with what he has in mind, that will no longer be the case. The appearance of your breasts, at least unclothed, will be permanently altered, albeit in a minor way. You have the right to decline, and nothing more will be said - but you should truly understand the full implications of what is intended.

'If I allow Gregor to go ahead, your nipples will be regularly stretched until they reach unusual length, well beyond the point of natural recovery. Even more than that, they will also become greatly thickened, as well as toughened. Their appearance - their texture and colour - will be changed. They will become leathery and dark, as if you had borne and suckled many times. It is unlikely that, once your term here is ended and you return to normal life, your nipples will ever return to an appearance of normality, even if you remove your rings. While the piercings will close, the nipples themselves will remain unusually large and thick. Their function will not be permanently impaired, but their appearance will have been altered so radically that you might, in later life, wish them other than Gregor will have made them. Such will be their size, both their length and their thickness, when my groom has finished with them that they will, in effect, be permanently deformed. They will never recover their original appearance nor indeed colour.' The Don stopped to allow what he had said to sink in, then smiled at Flame and continued.

'It is a 'deformity' - an abnormality if you prefer - that many might find attractive - but it will be inescapable.

'The effect of the regime Gregor intends to subject you to will be to leave you for life with nipples of probably two inches in length and in addition of strikingly dark colour, and so thickened and toughened that they will appear always at least semi-erect, even when completely relaxed. Probably even under a normal dress - certainly in evening wear or swimsuit - their size and protuberance will be impossible to disguise, their shape and permanent semi-stiffness impossible completely to conceal. And of course naked - or even simply topless, on a beach, for example - their unusual length and thickness and their dark colour will render them conspicuously evident.' Don Estanio waited for a moment to allow Jayne to digest the full impact of what she was being told.

'Do you give your consent, or do you wish for time to consider?' Without hesitation, Jayne/Flame slowly nodded her high-plumed head.

Thereafter and three evenings a week she accompanied Gregor to a corner of the long tack room where the harnesses for the stable's team of pony-girls were stored, cleaned and maintained by the grooms, for her special toughening sessions. The treatment was, as she soon discovered, cruelly demanding - but from the outset she was determined to see it through.

Without waiting for command, she would kneel before a low bench erected by Gregor for the purpose, exactly at breast height. Using the rings already through her nipples, Gregor would draw her teats fully forward until they were elastically stretched and elongated, then secure them by hooking the rings over two nails hammered into the bench for just this purpose.

With a light cane rod he would begin each session by repeatedly tapping along the length of each swelling nipple, bruising and enlarging the teat so that it swelled even more. Then with a small but stiff-bristled brush, like a large tooth-brush but the bristles made of fine soft brassy-gold wires, he would scrub and burnish the reddening teat flesh, brushing both along the stalk of the pulled-out nipple itself and around the base and aureola until to Flame it felt as though her nipples were on fire. Finally he would coat each stretched and rawly-reddened nipple with a mild etching liquid which stung and burned, but also caused the nipple to swell and the flesh itself quickly to grow tough and leathery.

Flame fought to hold herself still for this uncomfortable treatment, co-operating by leaning back against the restraint securing her by her nipples to the bench, stretching her breasts and the punished teats further so that Gregor could give them a thorough working. Thus her nipples were regularly toughened, stretched and caused to remain swollen, while steadily their colour darkened after each rough-handling session until after a few weeks they began to take on the colour and texture of softly tanned leather. It was not long before Jayne could see for herself the effect the treatment was having. And as she saw how her nipples thickened and lengthened, so she gave herself more readily and willingly to the discomfort of having the treatment performed.

Because of the special nature of her labial piercing, a normal crupper strap could not be used, which presented occasional control problems in both dressage and racing. Don Estanio watched Flame at work, and hit upon the solution. While Flame, still in her chariot and harnesses which included high neck collar and martingale, so she could not drop her head, stood as commanded stock still, she heard Don Estanio and Gregor working in front of her. She felt them pulling and tugging at her sex, parting her lips at the top of her slit, pulling at her inner flesh. A sudden stabbing sharp pain drove through her clitoris, at which she whinnied and shied, only to be flicked and commanded to stay. There was more painful tugging, a steady burning sensation at the top of her sex, another sharp stab at which she began to feel faint, light-headed, and struggled to steady herself, to hold still for whatever it was Don Estanio and Gregor were doing to her sex. The click of harness, some more words between Don Estanio and Gregor. The sharp pain at the base of her pubis had been replaced by a hot, throbbing ache. She wondered what had been done to her.

Gregor remounted the chariot and walked Flame on. As he softly called stop, she felt as normal the chariot shafts rise - but also again that excruciating stab between her legs. Various dressage movements were carried out, and again and again the stabbing pain, which caused Flame to exaggerate such movements as the high prance when stopping, the curving prance - which fully opened the knees to reveal the sexual cleft - when reversing. Don Estanio pronounced the remedy a complete success.

When she was returned to the stables to be washed-down and groomed, Flame with her eyes appealed to Gregor to know what had been done to her. He brought a tall mirror and, released from her harness trappings, she could examine herself. She saw that a tiny golden D-ring had been fitted to her at the upper junction of her labia, the pin of the D transfixing her clitoris which was thus pulled forward and outward so that it remained always visible at the top of her sex cleft, the ends of the through-pin, which held the D-ring, resting on the twin swells of her plumply depilated outer lips.

Instantly Jayne remembered the tall pony-girl she had seen when she first visited the stable, the girl whose clitoral conformation had also been put on permanent display by similar means - except that her stalk had been capped with ivory, riveted through. Now she herself was similarly modified. Everywhere she walked, everywhere she stood, anyone glancing at her would be able to see for themselves the extent of 'conformation', as her aunt had once described the appearance of her sexual organ. Her clitoris now would be always on display, pulled out and forwards from its discreet nest, blatantly thrust before the eye of the onlooker. The bar of the D-ring and the twin barbell-like endings of its lower pin served both to press back the swells of her labia and pull stalk and prepuce forward, and to keep the prepuce itself pulled back, revealing the little shaft. Thrust through the stalk, the pin served both to hold the slim morsel up to view and to keep it semi-erect. Even as she looked at herself and realised the way she was now permanently displayed, Jayne could feel the familiar tingle deep down between at the base of her belly, feel the familiar warm wetness squeeze out from between the tightly clamped lips of her sealed sex.

Gregor took the ring, demonstrated how it attached to an extra strap fitted to her girdle instead of the crupper strap. When he pulled up on the chariot, he also now pulled up on Flame's clitoris and clitoral hood. It was a very effective control.
