The groom turned and let out a sigh of relief.

"Ok, guys! Get her out!" he called and White Lightning was led out by two men who had made a great show of feeling every muscle in her body to check for strains after the gruelling race day. As one of them slipped a bridle over her head, the first one went to them with the maps. "Take her out to the East pastures and keep her there till I call. A couple of the lads will meet you and you can keep her busy for an hour or two."

The men grinned at each other. An hour or two with Lightning would suit them very nicely indeed. One man mounted the sulky and the other went to join those going by truck.

Sophie was glad of the chance to stretch her legs again. After the races she had been showered, her bottom had been flushed out and she had been rubbed down then taken on her leash round to the front of the house where a huge barbeque had been held. She had both rosettes pinned to her breasts and was immensely proud as Wilbur Beckington-Floyd himself led her around and boasted about her. When she could she stole glances down at her breasts and was pleased with the tracery of thin pink lines that adorned them. Usually a well whipped pony could look forward to some more male attention to other parts of her anatomy, but on this occasion everyone seemed more interested in talking about her. Finally however she was taken back to her stall, allowed to lie down and play host to any of the men - grooms, guests, whoever; it seemed as though Mr Floyd had declared her common property. She had to admit that she loved the first hour or so. After that her bottom began to sting all over again and this time her vagina followed suit fairly soon. The orgasms were very welcome however and she felt she had earned them. She had woken feeling stiff and sore again and even after the crusted semen had been showered off, she needed exercise to ease the stiffness in her legs.

There had been some activity around her stall, a tall, Arabic-looking man had looked her over from above the stall half-door. Mr Floyd had been hovering behind him and she had been surprised to realise that he was nervous about something. But since then, nothing.

Now she had been checked over with a fine tooth comb and at last she was tacked up and harnessed to a sulky. The groom who was driving her seemed to recognise that she needed to warm up gradually and let her work up to trotting speed gently. He made her walk from time to time and then whipped her back up to trotting and by the time they arrived at the gate to a pasture where cattle were grazing and a truck was waiting, she felt relaxed and loose.

A four man gang bang was exactly what the doctor ordered. They tied her to the gate with her arms and legs spread as wide as possible and took it in turns. Each of them entered her vagina and gratifyingly they took their time. As a result she climaxed with each of them. When they had finished with her she hung panting and sweating in the heat once more as her senses cleared and her heartbeat returned to normal. From over by the truck she heard beer cans being popped and the men settled down to relaxing - she hoped it was only temporarily.

She needn't have worried. The sight of her tied out on the gate soon re-ignited their interest and one of them came up to her and began to stroke and squeeze her breasts sending shards of pleasure shooting through her. She groaned and stirred in her bonds.

"Hey, guys," the man called. "She's ready to go again. What'll it be; heads or tails?"

A second man came towards her tossing a coin. "You call it!" he said.

"Heads," the man with his hands still mauling her breasts called.

"Tails! You go last!" the second man said.

They took her down and turned her around then pushed her head and shoulders through a gap in the bars of the gate before stretching her arms out again and tying them. She had had to spread her legs wide to get down to the level required and knew she was offering them everything they wanted. Her anus would be exposed between her spread buttocks, the slit of her sex would be perfectly open too, and she could feel the semen still leaking from her and dribbling down her thighs. The bar her arms were tied to crossed her chest just above her breasts and so they were hanging under her, ripe and full. She felt cool liquid applied to her bottom but couldn't tell if it was saliva or lube, whichever it was it did the job and she felt a finger slip easily inside her. As always the 'full' feeling took a moment to get used to and then she felt her sphincters stretch to accommodate another finger. Then she moaned as she felt yet another finger enter her and prise her open even further to allow the head of a cock began to nudge its way in. Even after all the action it had seen since she had become a ponygirl, her anus and rectum had remained tight and she hoped the cock was well lubricated. It did seem to be and she felt it open her up to its fullest extent and the man's pubic hair tickled the inner slopes of her buttocks as he came to rest against her. And certainly he did seem to want to rest, staying where he was, his cock impaling her rectum and it wasn't until she heard a can crumple and a sigh of satisfaction from behind her that she realised he had finished his drink before going back to buggering her. And as the shaft began to thrust and withdraw inside her she was vaguely aware that she ought to be outraged by such casual use of her body. But the feeling was so good she ignored it - and anyway if he was that relaxed about using her it probably meant that he would use her whenever the mood took him and she was fine with that.

He came quite quickly and was replaced almost immediately, the second cock sliding in smoothly on the emissions left by the first. This man was rougher with her and slammed himself against her backside as he rammed into her again and again. Then he reached forwards and grabbed her breasts so he had to buck his hips into her in order to maintain his grip. The stimulation at both ends of her body allowed her to begin to climb towards climax but he came before she could finish and was gone immediately. They left her alone for a moment and she felt renewed trickles of sperm run, rapidly cooling, down the backs of her thighs and ooze along her labia. She presumed that the third man wasn't so keen on sloppy seconds and indeed she felt him use a handkerchief to wipe some of it away before he inserted himself. His entry was a little more difficult and he had to force himself in, but even as she gritted her teeth against the pain she heard him sigh with pleasure at how tight she was. Once he was lodged fully inside her he was able to move more freely and came fairly quickly. The fourth man was obviously in a hurry after watching the other three and administered a no-nonsense, brisk buggering that left her agonisingly close to an orgasm when he wrenched himself out of her and she felt her anus gape for a second or so before it closed.

They left her where she was and went back to the truck for more beer but returned to heft and play with her breasts, slapping them and pinching them, making them swing beneath her chest and quite soon they were ready for 'Heads'.

Sophie was keen to get started. She didn't come from sucking cock but she did enjoy being close up to them and tasting them. The men released her and helped her to stand before they turned her away from the gate and had her kneel with her back to it then they tied her arms stretched out again. They had her shuffle her knees forward slightly so that she could lean back and offer her mouth up better. It also meant that her sperm streaked thighs were apart and her breasts were available. They whipped her with their belts while they drank some more beer and got ready for their final fling with her. She flinched and yelped under the harsh smacks of the doubled over leather as they targeted her groin, swinging the belts downwards and landing heavy swipes on her soft labial flesh. Her breasts suffered as well and in between shutting her eyes as the lashes landed, she could see the bulges in their trousers and was longing for them to get started. And at last the sight of her lacerated and well-fucked body was too much for one of them and he called a halt, stepping forwards as he undid his flies. His cock was stubby but reasonably thick and it tasted richly of her own body and his spunk. And to add to her degradation, he simply held her head and fucked her face with no finesse or care for her. He just wanted to feel the intimate confines of her mouth and throat around him as he came. And he wanted to be as deep inside her as he could get. Sophie had become practised at relaxing her throat during fellation and rode him out quite easily. He was deep enough inside her that she didn't even taste his spend but she enjoyed feeling the swelling pulses run through his shaft as he pumped into her. She hardly had time to draw breath before the second one was at her. He was longer and thinner and enjoyed her tongue exploring him, so when he came she got the full taste of his spunk before she swallowed it. The third cock was bigger and curved and she had trouble fitting him in and enjoyed it all the more for that. She got a real sense of achievement when she heard him roar his release into her sorely tested throat and then wrench himself out so that he could come over her face. She was able to look up at the shining purple dome as it splashed its liquor out onto her cheeks and forehead before it was plunged back into her mouth for her to lick it clean. She was gasping for breath after him and protested feebly when the last man slipped his length between her gaping lips, but he enjoyed her distress and fucked her face as cruelly as the first man had. She desperately tried to breathe through her nose and keep calm but he rammed so deeply into her that she panicked and choked on his come as it splashed thickly out. She hadn't been able to get him fully into her throat and it went up her nose as she choked and spluttered while the thick shaft itself filled her mouth and still thrust in vain for her throat. Then he withdrew and wiped himself on her face while his mates laughed and cheered.

Sophie hung where she was while they drank some more. She could feel sperm drying and tightening all over her body. She could taste it even as her belly ached for more. From under her eyelashes she watched the men, feeling nothing but admiration for the way they took their pleasure from her without worrying themselves about her at all. It made it all so much simpler to be a ponygirl.

And now there was only the run home to worry about. She watched a man take a phone call and then tell his colleague to get her tacked up again. It was time White Lightning was back in her stall.
