Gabrielle stared at the black leather open-face hood with its tall plume of purple ostrich feathers and her eyes shone with delight as she visualised herself wearing the lovely and clearly expensive present that her Master had provided for her.

It was exactly like the ones that she had seen adorning horses on the final evening of the International Horse Show when all the riders decorated their animals for the closing ceremony and she had always thought how beautiful and proud the horses looked with plumes nodding at every step.

Now, she was to display the same adornment as a pony-girl and she made herself control the immediate arousal that warmed her belly and stand perfectly still as her Master fitted the soft hood over her head and tightened the laces.

She hadn’t noticed the attached blinkers that restricted her view until then, but harnessed and leashed as she already was, there was nothing she could do about them and consoled herself with thoughts of how good she would look with the purple feathers adding another foot or more to her height.

Her Master reached into the box again and lifted out a second present and as Gabrielle saw that he held a long, silky mane of purple-dyed hair, she snorted through her bit in astonished amusement at the thought that he’d actually bought her a tail…………

But only until she noticed that the tail was attached to a fairly small, lozenge-shaped rubber plug…and realised just how the tail was going to be fitted………

Backing away until the leash to her collar drew taut, she stared pleadingly at his smiling face, already knowing that her gag-distorted protests would be ignored and that she was going to have to accept the humiliating addition to her pony-girl costume whether she liked it or not.

And as he calmly instructed her to bend over and spread her legs, she trembled to a scorching burst of heat that raced through her belly as he applied a thin film of lubricant to the plug and pressed its rounded tip against the puckered ring of her anal passage.

The automatic tightening of her muscles resisted its entry for several seconds, but as her Master chuckled and told her that if she relaxed it would make the insertion a lot less uncomfortable, Gabrielle forced herself to overcome her natural instincts and submit to his will.

Taking his time, her Master slowly pushed the plug into her body, allowing her time to get used to the unfamiliar sensations as her anal ring stretched to accommodate the thickest part of the device and then contracted around the narrower neck to form a tight seal and hold the rubber plug firmly inside her.

To Gabrielle’s immense relief, it was nothing like as uncomfortable as she had feared, creating a feeling of fullness in her lower belly that was actually quite pleasurable and even mildly arousing.

Although nowhere near as arousing as her knowledge that she now had a tail projecting from between her buttocks and couldn’t eject it without her hands.

Which were, as usual, immovably strapped behind her back and useless to her.

With the leash untied, her Master slapped the reins lightly across her shoulder-blades in the signal for her to walk and as she automatically slipped into the high-stepping gait of a pony-girl and he guided her out to the paddock, the plumes on her hood nodded, her silky tail swished back and forth against her thighs and the plug in her bottom shifted at every step.

At first, Gabrielle found the sensation deeply embarrassing, but as her body adapted to the presence of the rubber lozenge and she became accustomed to its movements inside her, she was able to relax and began to enjoy the low-level arousal it created.

A level that increased markedly when she responded to the reins’ instruction to trot and the plug jiggled faster and more erratically at the higher pace.

And when, after several minutes of trotting, her Master brought her to a halt, then calmly informed her that she was now fit enough to handle cantering, she gazed at him anxiously, immediately realising the effect the plug would have when she had to run.

But, as ever, she had no way to object or argue and as he added that he was quite sure she could cope and reattached the lunge-rein to her bit , she knew that she would have to obey.

“Walk on,” he ordered, then, “Trot now” and a minute later, “Canter, pony-girl” and as he flicked the whip across her buttocks, Gabrielle surged forward, her hobble-chain jingling and legs pumping.

It wasn’t a flat-out run, but it was considerably faster than the trot and as the plug made its presence felt by sliding back and forth in her bottom in time with the rapid swaying of her hips, her eyes opened wide in dismay and she stumbled, losing the smooth, even pace required of her.

“Steady, pony-girl,” he called sharply, “Concentrate. And keep those knees up,” the order accompanied by a stinging lash that brought a shrill squeal from her bit-gagged lips as a red stripe bloomed across her right buttock.

Gabrielle wanted to protest, to tell him that cantering was too hard and that she couldn’t possibly do what he wanted with the plug causing merciless havoc in her belly.

But she couldn’t and as the whip hissed out again, then again, and again, she was forced to abandon her objections and devote her every thought and effort to perfecting her performance and avoiding having yet more burning stripes added to the web of scarlet lines that criss-crossed her flexing bottom.

Humiliated, aroused and just a little bit frightened by how ruthlessly and easily she had been made to submit to his will yet again, Gabrielle slowed to a halt and stood still, her breasts heaving and legs quivering from her exertions as her Master walked up to her, took off the lunge-rein and casually knotted her reins to the top rail of the fence that surrounded the paddock.

“Well done, Gabrielle,” he smiled warmly, “That was really good and you look terrific with your pony-plumes and tail. I could see that was difficult, but knew you wouldn’t let me down. A little reward and a rest, I think, before we start the next stage of your training.”

His hands fondled her reddened buttocks, then moved lower, past her tail to the moist lips of her sex and as his touch instantly ignited a blaze of heat in her belly, she gasped and pressed backwards against his hand, her hips undulating in shamelessly erotic invitation.

He chuckled softly, enjoying her obvious need and let his fingers explore the slick velvet of her belly until she quivered and whimpered in almost unbearable pleasure and frustration.

Then took his fingers away and said, “Not yet, pony-girl. You still have work to do. Wait here and I’ll be back in a few minutes.”

Gabrielle gave a low moan and tried to turn towards him, her eyes filled with helpless longing, but as the reins snapped taut and she heard him walk away in the direction of the barn, her belly kicked strongly as she was forced to accept that she wasn’t going to be allowed to climax until he decided she had earned it.

And as it dawned on her that she was alone in the paddock, fully harnessed, tethered, gagged and virtually naked, Gabrielle stared anxiously around at the encircling woods, intensely aware of how helpless and vulnerable she was if anyone should happen to stumble across her in her Master’s absence.

Realistically, she knew that was highly unlikely…after all, she hadn’t seen a soul other than him in weeks…but that didn’t mean it was impossible……….

After several seemingly-endless minutes, her nerve cracked and she jerked her head against the reins in an effort to free herself.

But all that achieved was to tighten the knot, making escape even more impossible and bringing a groan from her as she realised that she had only made the situation worse, because her Master could hardly fail to see that she had tried to escape and might punish her for it.

She should have trusted him to ensure that no harm came to her and waited patiently for his return, but she had panicked.

It was a reason, but not an excuse and as Gabrielle understood that she had failed him and thought of his disappointment as he saw the evidence of her lack of trust, she groaned and felt her face redden in shame.

But what was done, was done and although she was annoyed with herself for being so weak and foolish, it was not too late to make amends.

If he punished her…..well, perhaps she deserved it….but when it was over, she would show him just how good a pony-girl she could be.

Just for a moment, Gabrielle frowned, wondering why she was so concerned about pleasing and impressing Matthew when he was the one who had tricked her into becoming a pony-girl and taken away her freedom…….?

Then, surprising even herself with her own calmness, she shrugged and decided not to waste time and energy on pointless speculation that no longer mattered.

Whatever the rights and wrongs of her situation, she was a pony-girl and he was her Master.

He wasn’t going to let her go and if truth be told, she didn’t actually want him to.

Not any more.

During her weeks of training, she had come to love being a pony-girl, to enjoy being harnessed and having to obey the commanding tug of reins at her bit, to relish the feel of sunshine and cooling breezes on her naked flesh, even to find a certain guilty excitement in the stinging bite of a whip across her buttocks, urging her on to greater efforts…..but above all else, the touch of her Master’s hands and lips on her body, rewarding her with overwhelming pleasure, eclipsed only by the soaring, undreamed-of ecstasy of a full climax when she was taken by him.

Her life had changed out of all recognition since their first meeting at the International Horse Show and as Gabrielle tried to imagine returning to the dull, boring routine that had once filled her days, her eyes gleamed with amusement.

Even if she was given the opportunity, which seemed highly unlikely, she knew she wouldn’t even consider it and as the door of the barn shut with a thud behind her, she straightened her spine and thrust out her breasts to display her body for her Master and prepared to resume her training.

As his footsteps approached, she heard an odd rustling sound, but couldn’t turn to look and even as she tried to guess what was causing it, it stopped and her Master came into her view, reaching out to untie her reins from the rail.

“Hmm,” he said, tugging at the knot, “Been pulling, have you? Well, it’s never too early to start practising, I suppose.”

She didn’t understand what he meant and was just relieved that he didn’t seem upset, but as the reins came loose and he turned her around, his words suddenly made perfect sense.

Standing on the grass was a miniature carriage, its two spoked wheels supporting a tubular frame with a single canvas seat, a pair of long shafts projecting from the front………………

The rubber-covered bit between her teeth prevented her from actually laughing, but as her mind instantly flew back to the last night of the Horse show and she remembered how intrigued she had been by Matthew’s suggestion that she try being a pony-girl, she gave a snort of half-delighted, half-apprehensive surprise, realising that even then, he must have had this very moment in mind.

Just like an angler, he had baited his line and she, the unsuspecting fish, had swallowed it, hook, line and sinker.

And now she was about to find out whether being harnessed to a carriage and having to pull him around wherever he chose to drive her, would really be as much fun and as exciting as she had thought at the time……………

With a firm tug on her reins, he led her over to the carriage and let her have a good look, “It’s an aluminium frame and those are bicycle wheels, so it weighs very little,” he explained calmly, “You go between the shafts, of course, and once they’re attached to that waist-belt and I’m in the seat, we’ll be all set for a nice little trot to get you used to pulling. So turn around and back in between the shafts and I’ll get you ready.”

His air of confident authority sent a ripple of arousal through her belly and although she tried to pretend to be reluctant, her heart wasn’t in it and after a brief hesitation, she stepped backwards and let him fit the wide leather belt around her already-corseted waist.

“This takes all the strain,” he chuckled, pulling all three buckles one notch tighter than she would have wished, “So it has to be a snug fit.”

Snug was hardly the word Gabrielle would have chosen to describe it and as he stood up, she glared at him in the only form of protest left to her.

Unfortunately, he was fireproof and as his fingers captured her nipples and twirled the sensitive buds, she writhed and squealed, hobble-chains jingling as she danced from foot to foot, her body shot through with scorching arousal.

“Stand still, pony-girl,” he snapped and she froze, her eyes wide with alarm as he snatched up his whip and flicked it lightly across her left breast, “You should know better than to break position when you are in harness. Clearly, you need to be reminded of that. Display position, now.”

Faster than conscious thought, Gabrielle jerked her shoulders back and spread her legs to the limit of her hobble, presenting her body as she had been trained her throat working as she gulped nervously.

“Better,” he said coldly and as he flicked each of her rigid nipples in turn five or six times, then switched his attentions to the stiff button of her clitoris and tapped it firmly with the tip of his crop, she fought desperately not to give in to the savage jolts of electrifying arousal that speared into her belly.

It was torture of the most deliciously cruel and incredibly erotic kind and when he finally lowered his crop and said flatly, “Much better, pony-girl. That is the standard of obedience and discipline I expect of you and which you will give from now on,” Gabrielle shuddered helplessly, her whole body aflame with need and her mind reeling to the appalling realisation that if his whip had continued for even a few moments longer, she would have been unable to hold back the climax that seethed and churned in her belly.

Stunned by her own responses to the ruthless subjugation imposed on her by her Master, she stood passively as the shafts of the carriage were lifted and clipped to the side rings of her waist-belt, only snapping out of her shock when she felt pressure at the belt as he climbed into the seat behind her.

The reins slapped across her shoulders, accompanied by a stinging lash to her buttocks from his whip and as Gabrielle yelped and lunged forward, the carriage jerked into motion.

“Whoa,” he shouted, pulling back hard on the reins and as she came to a halt, he gave a heavy sigh, “That was terrible, pony-girl. It’s supposed to be nice and smooth, not a fairground ride. So we’ll start again and this time, do it properly, or we’ll keep at it until you get it right. I’m in no hurry and my whip has got all day. OK, off we go then.”

Once again, the reins and whip sent their clear message, but this time Gabrielle was better prepared and instead of jerking away from the hot stripe on her bottom, she made herself accept the smarting pain and leaned into her waist-belt until she felt the carriage begin to roll forward, before lifting her legs into a high-stepping walk.

To her surprise, the carriage was much lighter than she had feared and so well balanced that most of her Master’s weight was taken by the wheels, but the relief she felt at discovering that she was equal to the task of pulling him, couldn’t compensate for the alarming fact that she was still humiliatingly aroused.

The aching of her engorged nipples and the relentless throbbing of her clitoris refused to go away, combining with the jiggling of the plug holding her new tail in her bottom to keep her teetering on the brink of orgasm, but not quite able to achieve release.

Horribly frustrated and in need, Gabrielle groaned in anguish as the reins gave the signal for her to trot and as she increased speed in obedient response, she felt a trickle of her juices ooze from her sex and slide down her thighs to betray the havoc raging through her belly.

Behind her, a deep chuckle told her that her Master had seen the proof of her sexual heat, but even as she reddened in shame, couldn’t help but feel a thrill of pride and excitement at the thought of how he must be enjoying the sight of her flexing bottom and thighs and revelling in her submission to his will.

Knowing that with a casual tug of her reins or a lazy flick of his whip, he could exert total control over her and make her do his bidding.

And as he drove her around and around the paddock, turning her left and right as he chose and varying her speed from trot, to canter, to walk and back again, then giving her a little time to recover before beginning again, Gabrielle surrendered willing and totally to her plight, her passion and desire to serve and please her Master burning like a bright, hot flame in her belly.

A flame she knew would never be fully extinguished and which made her the true pony-girl she was and would always be………….

Brought at last to a halt, she immediately displayed her body and stood perfectly still as her Master got down from the carriage and inspected her, smiling at the beads of sweat that proved how hard she had worked and the tell-tale silvery trails on her thighs that marked the extent of her need.

“Good work, Gabrielle,” he told her approvingly, “You’re a natural and after the first little hiccup, you made it look as though you’d been a trained pony-girl and pulling carriages your whole life instead of just a few weeks. I’m impressed, so let’s get you unhitched and then I’ll give you a nice reward.”

Releasing her from between the shafts, he led her over to the fence and tied her reins to the top rail, shortening the leash so that she was forced to bend forward until her torso was parallel to the ground and her nose only an inch from the heavy wood.

Unable to see downwards past the rail, Gabrielle was intensely aware that her breasts dangled invitingly and as his crop tapped her thighs, she obeyed the unspoken order and spread her ankles as far as her hobble-chain would permit, exposing the glistening folds of her sex behind her purple tail.

“Walk in place,” he commanded and her face flamed a vivid scarlet as she lifted each leg in turn and felt her tail swish across the backs of her thighs, every step providing a momentary glimpse of her moist, pink sex-cleft as her buttocks swayed from side to side.

From behind her came the unmistakable rasp of a zip being opened and as her tail was brushed aside and his thick, hard shaft nudged at the entry to her belly, Gabrielle gasped and faltered.

Strong fingers snaked around her bent body, capturing her stiff nipples and giving a cruel pinch to the sensitive buds and as he snapped, “Keep the pace, pony-girl,” she shuddered in ferocious arousal, the sharp twinges of pain only adding to the inferno in her belly as she was forced to continue.

At each step his shaft sank a fraction deeper, the movement of her hips massaging his rigid flesh and the flexing of her buttocks slowly and automatically drawing it further into her body as she pranced from foot to foot.

There was nothing she could do to stop it and as her own actions assisted him to penetrate her, Gabrielle quivered and whimpered as he inched forward until his full length was solidly embedded, impaling and filling her with his iron-hard maleness.

“Trot,” he snapped, pinching her nipples a second time and as she squealed and doubled her speed, the amazing sensation of her internal muscles clenching and releasing as she rose and fell on his rigid shaft…and the realisation that she was being forced to ravage herself while he simply stood still and made her do all the work…was too much for her to resist.

From deep down in her belly, a giant orgasm raged upwards and as a flood of her juices burst into her sex and over his shaft, Gabrielle climaxed massively to the thrilling ecstasy of total submission to her Master and the overwhelming pleasure that her willing service and subjugation sent racing through her body and mind.

Bathed in the wet heat of her spasms, her Master clamped his hands on her breasts, rolling and squeezing her nipples as his own passion neared its peak and as his spend jetted into her juddering belly, Gabrielle screamed her desire and surrender into her bit-gag and hurtled into a second climax even more intense than her first.

For endless minutes, Master and pony-girl shared the rapture of simultaneous orgasm, their bodies locked together until both were sated and her frenzied contractions began to abate.

Stepping back, he pulled his drained shaft from her quivering sex and smiled as he realised that in spite of her immense climaxes, her booted feet still tramped up and down in the rhythm of the trot he had ordered her to maintain, proving beyond any doubt the depth and effectiveness of the ingrained training he had imposed upon her.

“Halt,” he told her and as she instantly stopped and he heard her give a soft gasp as she understood just how thoroughly she had been conditioned to carry out his commands, he chuckled in satisfaction, knowing that she would be both embarrassed and hopelessly excited by such unmistakable proof of the success of his efforts to transform her into his obedient pony-girl.

A task which was well on the way to being completed……………….

Like her Master, Gabrielle was only too well aware of how far she had come since the fateful evening when she had first heard his astonishing suggestion that she should become his pony-girl.

At the time, she had had no idea that it would be anything more than a sexy game and it had only been later, after she had signed the Bill of Sale and accepted the solitary pound coin she had agreed on as the price of her purchase, that she had learned just how serious and determined Matthew was.

Of course, she had tried to object and argue, but all to no avail and as she had realised that he was not going to let her go, or permit her to defy his wishes, her will-power and self-control had been undermined and fatally weakened by a combination of a deep vein of submissiveness she had not even known was in her nature and an irresistible curiosity to find out just how far he would go to make her his.

With a potent and addictive blend of bondage, helplessness, strict discipline and devastating sexual pleasure added into the mixture, she had been drawn in so fast and so far that by the time she had finally recognised what had happened, it was already too late to turn back.

Because she no longer wanted to…………………….

As her Master untied her reins from the fence and turned her to face him, Gabrielle arched her spine to display her body, her belly swirling with heat as he smiled and said, “Thank you, Gabrielle. I am so pleased and proud of you, you know. You are quite superb and I shall never free you. You are mine, my pony-girl and that is what you will always be. So, one more hour of training and then you can rest.”

She gazed into his eyes and shivered in delicious fright, knowing that he meant every word.

Tired though she was and although she would have much preferred to be taken back to her stable and allowed to recover from her exertions, she was a harnessed pony-girl and it was not for a pony to defy the wishes of her owner and Master.

If he required her to train for a further hour, then a further hour of training it would be and as she was led back to the cart and fastened between the shafts, Gabrielle took a deep breath, forcing herself to ignore the swirling heat in her belly and concentrate on the perfection of her responses to the reins and whip.

She could do it…she would do it…and as the bit in her mouth tugged firmly, she moved smoothly forward in the elegant, graceful rhythm of the trot, her knees lifting high, the plumes atop her hood nodding and the tail emerging from her plugged anus swishing gaily at every step………………
