Chantal was over the moon and announced to Blaise: “This filly is exceptional, I want to have her mated. Find me a first-class stallion. If we choose the right one, her foals will be even more suited to racing than she is herself.”

This sentence made Louise quiver when she heard it! Was it just one of those provocative jokes which Chantal made when she was in a good mood and just wanted to make her filly tremble, or was it more serious? The light smile on Blaise’s lips did not reassure her.

When, two days later, he took her along to the handing-over room where he had first marked her with red-hot iron, she felt considerable concern. This time, he laid her down on her back and, fixing her ankles to ropes from pulleys from the roof, drew her legs slightly upwards and apart. Her naked sex was thus exposed, the lips pulling on the wire that sutured them. She remained there for a good hour, waiting for someone to deal with her.

Then she heard the noise of a truck, which stopped in front of the door, then the noise of something or somebody and the scraping of a metal shoe. She raised her head and looked between her legs and gasped at the sight! There stood a small stocky creature – a man?

He was very hairy, so much so that it was impossible to tell his colour. His head and pubis were shaven. What struck her most were his muscles. Outrageously developed, almost gorilla-like, his arm muscles forced him to keep his arms away from his body. His legs were short and very strong. His head seemed to be part of his body so short and thick was his neck. His hands were handcuffed to the broad leather belt that was tight round his waist.

His Master, whom Louise did not know, tried to control him by pulling on a leash attached to his nostrils. As soon as the man saw the filly that was to be offered to him, he gave bestial howls of pleasure and tried to spring towards her. His Master had enormous difficulty in restraining him; Blaise and a young stableman helped and then bound the stud with leather straps.

Louise stiffened, terrified. Her glance then dropped down his torso. From his belly an enormous entirely shaven dark and twisted member emerged. Louise had never seen a man’s sex before and that made this one appear even more monstrous to her untutored eye. The end of the creature’s sex was pierced by a heavy ring, which was fixed to a strap encircling his testicles, themselves the size of goose eggs, and prevented his sex from fully extending. The excitation caused cries of pain to come from the man as his imminent erection made the flesh take on a polished and purplish appearance.

Once the ring had been removed by the stableman, the creature’s member emerged, finally free. Some thirty centimetres in length, almost as broad as his forearm, it sprung up and before her eyes grew even bigger, as he stared at the young filly. He gave more howls of lust and only the blows from a riding crop calmed him somewhat.

Blaise then approached the girl who lay with splayed legs and her sex offered open to view. He took out a long bladed knife and passed it between Louise’s slit and the gold wire, which sutured her sex. After having passed the knife entirely under the wire, he cut it with a sudden jerk. The wire opened and the threads were easily removed but the lips remained closed. The girl was ready.

It was important, now that the man-thing was fully aroused, that he did not damage, by his preliminaries, the girl’s fragile sex. She, in turn was overtaken by attacks of animal lust, all the more strong as she had been frustrated over so many months.

The creature’s master relaxed his hold and Louise watched as the creature’s member shook off the enormous pink foreskin, and became rock-hard. He had calmed a little and emitted small growls of pleasure that suddenly began to quicken. His master, deciding that the creature was ready, released the human animal. Hardly had he unfastened the bonds that restrained it when it sprang towards the girl with an enormous howl, to insert his huge member brutally into the vagina of the filly.

Louise howled with pain and fright when the sex ran harshly up against her welded lips without being able to penetrate. Louise tried to struggle but was firmly strapped and Blaise held her in such a way that her belly was well positioned.

The creature began again, putting more force into his thrust, then again and again, and, finally, with an enormous howl of satisfaction which mixed with acute cries from the girl, he inserted himself, the natural joining of the lips, sewn for several months gave way and her maidenhead tore. Three thrusts were enough for him to explode his seed into the belly of the mare, the sperm so plentiful that it overflowed from Louise’s sex. At once its master redoubled his blows with the riding crop on the rutting male in order to uncouple it from Louise and to bring it back into its van, in which it was locked up it again.

As for Blaise, he detached Louise’s legs from their straps and raised them again, strapping her ankles together and drawing her legs high over the bench, so that the sperm would penetrate well, deep into of the vagina of the filly, and so that the insemination would succeed.

She remained there, legs raised, for more than an hour. She saw Chantal praise Blaise for his efficient conduct of the operation and lengthily stroked the belly of her filly of which she was so proud. Louise shared also this feeling and felt honoured to have been part of this equine manœuvre

Her mating had a remarkable effect on Louise. As she became sure that she was in foal she became calmer and more obedient than before. Secure and relaxed in herself, she was sure of her position in the stables and happy in her animal status. Her dreams of a day in the future when she would regain her freedom and with it a large dowry receded.

Louise became a model filly. Flexible and obedient. The fact that she had been successfully covered became more and more obvious. When Blaise took her in the evening to deal with her needs, there was no longer any necessity to attach her to the post as he had always done at the beginning. She awaited the return of the stableman patiently.

She learned from him the need to care for her driver by making sure that the wheels of the carriage always ran on hard, smooth ground. At Chantal’s request, he trained her to be ridden directly: a saddle resting on her shoulders, a bit in her jaw from which he had had the vet extract the teeth on the sides so that a pull on the reins brought her head quickly round. Thanks also to small sharp-edged points fixed at the toes of her riding boots, the rider could completely control the filly by pricking her buttocks.

Even as her belly swelled, Louise remained robust, fast and strong and could easily carry a light rider like Chantal. The latter took to riding Louise in this manner each morning for long walks in forest, herself sometimes wearing only her boots and carrying her riding crop. Afterwards Chantal felt the hollow of Louise’s thighs and always found them damp with pleasure.

So continued a series of truly happy days for Louise, She knew that she would soon be taken to the vet for him to supervise her when she came to foal. She knew too that her young colt, whether male or female would, in time, follow in her steps as a member of Chantal’s stable.

Later, as she lay on her back with her legs tied well apart in the throes of giving birth, she saw Chantal, the vet and Blaise watching her and it occurred to her that she had once been human too. She put the thought from her mind. She was happy as she was, a pony girl.
