“Oh, Rarity!”

Fluttershy shook her head, the yellow pony’s lips turning down, considering the sheer amount of stress her friend was under. Rarity’s boutique was piled high with clothes in the ultimate display of chaos, although it was a wonder indeed that the well-known and always well-dressed fashionista had been working on all of those clothes all at once – difficult to believe, in fact, for those who did not know her personally. But Fluttershy was one of her oldest friends, after the pegasus, of course, had moved to Ponyville and some would have said that Fluttershy knew Rarity better than she knew herself.

And that was just why she knew that the white pony on the floor wailing (well, okay, that was a little bit of a giveaway) needed a break from reality – if only for some time. She’d have to crack on with her winter line of clothes sooner or later, of course, but there was a time and a place for everything and Rarity, sometimes, could not see the wood for the trees.

As Rarity whimpered and wailed, puckering her lips with big, fat, dramatic globs of tears trickling down her face, Fluttershy knew there was only one thing she could do for her. And, to be fair, it was a pretty lovely thing she had in mind to take a little of the weight off the mind of her very best spa buddy.

“Oh...” Fluttershy shook her head, tail tucked down as her wings fluttered, a loose feather drifting off as Rarity sprawled on her back – on the fainting couch by this point. “Wait here!”

As if Rarity was going anywhere else as, in her point of view, the world crumbled around her, clothes and fabric and sequins flitting before her eyes as if in some kind of horror show that she could neither stop nor control. Rarity whimpered and squeaked, gasping and fighting for breath, but even she had to come back to her sense of poise and rationality – couture, darling! – at some point, using the blue glow of her magic to set her little corner of the world to rights again.

Just a lapse in judgement, she told herself, a little interlude. All would be well, never fear! But just where had sweet Fluttershy gone?

She was standing before the three-sided mirror and miniature stage when the bell tinkled again but so focused was she on her notes and the pen levitated in the hold of her magic that she did not even turn around. Her red glasses balanced on her nose and a more daring observer may have pointed out that her tongue was poking out the side of her mouth in concentration. Fluttershy and her charge, however, were not such daring observers.

“Oh, darling, I’m ever so sorry about my little, ah, meltdown back there,” Rarity said, studying the clipboard as a hint of a blush coloured her cheeks. “You see, I really did find myself in ever such a frazzle – but it’s all better now! Onwards and upwards, as they always say! Or is that what they say? What do you think? Oh, look at me – I don’t even know what it is that they say!”

Squealing, she danced in place – a move that was not quite a jig but that may not have been out of place if performed at the Ponyville carnival. Smiling, Fluttershy draped a wing over her back, tugging her in close as if they were two conspirators coming up with a ploy, although one of them was surely more composed than the other.

“Oh, Rarity, you’ve been working ever so hard,” Fluttershy murmured, her voice taking on the hue of a husky whisper over a glass of red wine. “It’s time you had a break, there’s time left to do the work that needs to be done. But you’re never going to get anything done when you’re in such a tizzy!”

Fluttershy giggled, lightening the mood of the room just a little. It was enough.

“That’s what you say, isn’t it? But if you’re going to be jittery and whimpering, Rarity, it should be for the right reasons... Don’t you think so?”

Rarity shivered, eyes hazing over, just a little, tension slipping from the line of her tautly held tail.

“What... Ah, darling, what are you proposing?”

“Nothing you have not enjoyed before, Rarity, but I thought that my pony pet would be more useful to you today than me!”

Stepping back with a flourish, she revealed Arctic, a white stallion with his blue mane hanging into his eyes with the tilt of his sheepishly lowered head, a collar around his neck bearing the tag of a pink butterfly: his mistress’ cutie mark. He was a sight to behold, her pet pony, but it was more what was between his legs than his physical stature that gleaned the attention of many a mare – if Fluttershy was willing to share her consenting slave with anyone, of course, that was. It all came down to her, after all, as the proud mistress mare stepped back, waving to Rarity with a wink that promised that she was to hear the full tale of sexy times when Rarity was good and done with him.

Arctic would have said something but the bit gag wedged in behind his teeth silenced him, although Rarity would, undoubtedly, delight in his muffled whines and whimpers later in the day. The stallion rocked his hips lightly from one side to the other, his back hooves kept together by means of hobbles, although the length of chain that Fluttershy had allowed him there was rather decidedly short for what he would have found personally comfortable. Not for walking, of course, but for maintaining the necessary space between his hind legs that kept his balls at a comfortable spacing, the huge orbs swinging and squishing between his legs, oversized and always seeming to swell more and more each and every time Rarity had the good fortune to lay eyes on them. His cock too had been forced out and throbbing, a tight cock ring around the base ensuring that the thrum of pain and pinching pressure kept the huge organ out and on show at all times, although just how Fluttershy had gotten him across to the boutique without anyone questioning her, well... That was another story that could make Arctic blush!

“Oh...”

Rarity’s jaw dropped but not even the prim and proper pony could stop a smile from pulling at her lips, shooting Fluttershy a look of pure gratitude.

“Now, Rarity, no need to thank me,” Fluttershy cut across her as she started to speak, waving a hoof with a smirk. “It’s all fine, anything for my friends... Drop him off to me later, okay? And make sure that he behaves for you... The reins are yours!”

Fluttershy herself seemed to be in a rush to leave but that was only because she knew that her friend truly needed the break and relief at that time, trotting off at a brisk pace, the tinkling bell over the door signalling her departure. The only remnant of her was the pony pet she had left in her wake, Arctic’s eyes wide and plaintive, although he trembled more in anticipation of what was to come rather than any sense of fear that could be so played out on his little heart.

“Hm...” Rarity’s eyes glittered and she set her glasses deliberately aside, folding the arms in with the aid of her magic. “Dear, lock the front door.”

At least that was an easy task. Somewhat, anyway, with the hobble restricting his movements but it was not as if Arctic wanted anyone else to be able to walk in on them either as he huffed and snorted around the gag, ears waggling with the strain of anxiety. What was she going to do to him? Fluttershy hadn’t told him why he was there – yet again! – and it was something that he was going to have to seemingly work out for himself with the fashionista pony’s eyes boring into him with a hunger that stirred a deeper sense of submission in his gut.

The lights flipped off as he locked the door and, against himself, Arctic gulped, although any saliva that was in his mouth seemed more apt to drool out from the corners of his lips than anything else... How embarrassing! He almost didn’t want to turn back around as a red spotlight illuminated the staging area, the clothes and what made up the boutique cast into darkness, the shutters drawn against the light of a world that was not in keeping with the fetish that Rarity needed to play out for her own sense of self-satisfaction and, well, yes – relief too. That was important and that was what he was there for, breathing shortly and shallowly as he lowered his nose to the ground and bowed before her.

I’m here to serve.

His training had done him well and the tag jingling lightly on his collar told him too that he was right where he belonged, muscles tense even as calm seeped through his mind. He hiked his tail up just as he knew that Rarity liked (Fluttershy had given him a briefing after his last session of use by the purple-haired mare, her curls looser than ever before that time) and the mare murmured her approval, swapping her clothes with magic, the blue glow seeming out of keeping with the red mood lighting that she had set up for herself. But Rarity was one who liked to stage it all, drawing his heart beat into a pounding, fluttering frenzy that could only be tamed by one means and one means alone.

“Come here, darling.”

He could only obey, heart pounding, hammering its way against the cage of his ribs, although there was as little hope of it escaping his body as he had of Rarity. The point of it all was that neither truly wanted to escape too, which was just the way it was supposed to be. The mare stood before him with her head held high, clad in a seductive latex harness that crisscrossed her body in just the right way to highlight the very best parts of her anatomy – not that she had any bad parts at all to speak of anyway! Her udders were even highlighted by it, moderately plump in size, and he groaned, trying not to stare at her for too long even as his nostrils flared.

“Take it all in, darling,” she whispered, words clawing their way out of her throat as her breath caught, need pumping up full and thick. “But this is for me.”

He knew that. Of course, it would have been impossible to not know that as Rarity stalked around him, letting him see her from all angles, how the curves of her hindquarters were drawn up sharp and bold, tail lifted, displaying a twitching, winking marehood and delicious bud of a tail hole. He zeroed in on her sex, although his hooves remained rooted in place, Rarity letting out a delectable little giggle as she turned her cunny on him.

“Oh, darling... Something you want?”

Oh, yes – yes, yes, yes! There was something very much there that he wanted and the stallion whimpered and whined, pushing his tongue hopelessly and helplessly against the gag in his mouth. As if on cue, her marehood winked and pushed out a thick stream of pussy-juice, her sex as eager for the use of him as her mind was. Stress relief truly was the best reason for sex but anyone would have thought that as Rarity backed up aggressively on his muzzle, not even considering that his needs may have, at least in some, small way, been different to hers.

Oh no... She moaned as she rubbed her marehood over his muzzle, staining and marking him with her essence, the sweetness of her honey pot. He couldn’t lick her slit but that was alright – she’d have her fill of that soon enough, once she’d teased and abused the randy pet into the state of a stallion that she really needed for herself! Yet there were illicit pleasures to be taken too as she moaned and whinnied, stomping a hind off, her tail falling over his head in a luxurious fall, eyes half-lidded with the encroach of pleasure that she could not wait to take for herself. His nose pressed over her fat, throbbing clit and she gasped, the line of her back drawing taut and a fresh spurt of arousal soaking his muzzle even as he pushed and pushed, haplessly, at the gag like a creature possessed. He’d reek of her for days – she’d make sure of that!

“Get down!”

She snapped, impatient as he did not seem to read her mind – but the beauty of it all was that she could say whatever she wanted, do whatever she wanted. Arctic was a pet to be used and abused and he adored it too: he’d told her so himself during one of the rare times where his muzzle wasn’t occupied with either a gag or a mare’s cunny, the warmth of one, oh... Oh, it was more than enough to make his mind wander and, yet again if not for the gag, he would have gone slack-jawed as a flogger snapped beside his head, Rarity using her magic to wield the tool with such force that she made the leather tails snap as if she would a bullwhip.

“Now!”

He didn’t know just how she wanted him but he had to hasten to obey, dropping to the stage with a grunt and a thunk that denoted the speed of it. Yet he’d delayed his response to her for too long and there was no way that he was getting away with that without punishment but, well, that was just what Rarity wanted from him as she loomed over him, striking his hindquarters without care for his response. He could have howled from the pain of the strike or not but it wasn’t going to stop her from forcibly yanking his tail up with her magic and keeping it hiked well out of the way for her, layering his round, muscled rear-cheeks with lashes that, under different circumstances, could have been considered loving. With her, however, and him as he lay there, they were anything but.

“Tsk, tsk... You need more training. But I’m happy to provide, stallion. Or should I call you colt again?”

Smirking, Rarity cocked her head at him, flicking her tail, just to wash her aroma, the headiness of it all, over him all the more. A push of her dominant hoof was all that it took to get him over on his back, his cock on full show, twitching and drooling so much pre-cum that it would have been considered an actual orgasm for a normal stallion. But he was no normal stallion and that was just one of the reasons that Fluttershy had chosen him, Rarity grinning lewdly and trailing the strands of the flogger over his cock, letting him feel every last inch of the thin leather strips that could bring such a shiver in the prelude of pain.

“Should I break these?” She crooned, although she was not expecting an answer as she prodded his balls crudely. “Such fat pony-nuts... You should use them more, little colt, but your mistress would rather see them pumped up nice and full, wouldn’t she?”

Arctic shivered and nodded, eyes closed. The hoof that struck his muzzle, snapping it to the side, quickly reminded him to keep them open.

“Eyes open! Now... Let’s see how much you can take...”

The flogger was clearly not to be her tool of choice and he sucked in needy breath after breath through his nostrils as she hung it over his dick as if it was a clothes rack, something that she would want again later. Yet she had all the tools she could ever want to abuse a stallion-pet like him floating in with a chest, her magic wrapped lovingly around the oak. The first he knew of anything actually coming out of the chest itself, however, was a slick, cold sensation at the tip of his cock, bearing in and down as he tried not to squeal and kick out, his hind hooves still, thankfully, hobbled. At least those meant that he wouldn’t accidentally kick Rarity and be punished further for his crimes.

The sounding rod was slender but not the thinnest one in her collection, tipped with a diamond that had been recovered from the Diamond Dog mines on a certain eventful expedition. Rarity giggled gleefully, tail swishing, as she filled the poor little colt’s dick with it, delighting in how much he could take. Oh, she just couldn’t find a stallion with the stomach to satisfy her in that way anymore but Arctic was the perfect victim as she vindictively twisted the sounding rod, smooth, clean metal grinding against his overly sensitive passage as his head swam, metal bit gag clanking obnoxiously against his teeth. But of all the sensations that there were going around, that was the one that he noticed the most.

“Oh...” She affected disappointment, staring down at his cock as if something had displeased her. “It’s too small, isn’t it?”

No! He twisted and grunted and panted but there was no use in telling Rarity that he wasn’t ready for the bigger one as yet, even though it was his own sense of wariness and trepidation that was forever stopping him from going too hard too soon. It was good, in that sense, that he had dominant mares around him to aggressively force him by just what he thought his limits were, driving him on as he panted and heaved, hips jerking as his cock tried to shoot out a load of pre-cum or maybe even his first orgasm of the session around the rod. But Rarity was too skilled and swapped one sounding rod for the next, larger, size, pushing it deep with more crudity than she would if she’d been engaging with the play with a partner she deemed of the same status as her.

She grinned, ears flicking to catch his whimpers, sealing his cum within his cock. He just wasn’t like the unicorn.

“There now...”

Her croon did not relieve him as she stood astride his head, hips in position and one hind hoof trapping his forelegs each, the weight of her crushing them down into the stage. Of course, she could have retreated into more private quarters to retrieve her bondage equipment but, hey, she didn’t have time for that when Arctic was right there and simply begging to be used and abused, the stallion’s chest heaving and fluttering as she took her leave of him and, finally, got to do something that she had perhaps left a little too long.

“Ahhhh!”

A hot stream of mare-piss spattered his muzzle as she pinned him nonchalantly in place, hips wiggling lightly to ensure that his mane was well soaked in the stream. It did not discriminate on where it landed, damping his mane down in wet curls against his neck, the stallion half-closing his eyes as much as he wanted to see what was happening, the depravity of it all thrumming through his soul. He could not have admitted it out loud, of course, but that was just how it was meant to be as she soaked him in urine, knowing that it was not her, undoubtedly, that would have to clean up the mess afterwards.

“Oh, my!”

Rarity giggled, squatting down lower, putting more and more weight on his legs. Pissing directly over his nose as the stream, slowly, edged off, she moaned and rolled her head luxuriously from one side to the other.

“I didn’t realise how badly I needed that!”

But there were other things she needed too as she whipped his gag away so quickly with her magic that he was left wondering just what had happened as her marehood descended on his mouth. His tongue could only go to work and he lapped and suckled at her folds wantonly, pushing his tongue inside and driving it up as deep as it could possibly go. He was put to work in the best way he knew how but, still, the pain of having his tunnel stretched twisted his guts unpleasantly. The sounding rod was not to be moved but the brush of her hoof up his cock made him jerk and convulse, eyes wide and desperate as his needy balls tried to cum and yet found himself, between the sounding rod and the cock ring, hopelessly unable to. It truly was pathetic that his body even tried, ultimately.

“Oh, colt, you never give up do you?”

Rarity taunted him as cum backed up in his balls, the magic in the potions that Fluttershy kept making him drink forcing his seed to replenish as soon as it was spent – but where was it all supposed to go if his body thought it was spent and yet it went nowhere? His balls swelled, spilling heavily over his body, the throb of cum churning within them only the beginning. He just had to focus on Rarity, breath ragged in his chest, licking and nuzzling, suckling her clit into his mouth, focusing on the rise of her whinny as she hit her climax too. The flood of mare-juice over his muzzle was nowhere near enough to wipe the aroma of urine, heady and acrid, from his coat but it was something else and he readily lapped down every drop she had to offer him.

Thick and tart, it seemed to cling to his muzzle as his tongue swiped along the side, barely able to keep up with the flow of all that she produced. Caught up in the moment, Arctic was dimly aware that his cock was throbbing again, squeezing down on the sounding rod, trying to cum even as his balls churned and ached and grew. It was the way of it and in some small part of his mind he only hoped that he would not grow so large that he couldn’t get out the door this time! That, however, was likely a hope that he would have done better to cast aside.

“Mmmph...” Rarity hung her head, panting and sweeping her mane back into place as she took a moment to compose herself. “I forget how good your tongue is... I’ll just have to make better use of it!”

Her marehood ground down again and he did his job dutifully, sinking deeper and deeper into such a state of submission that time no longer seemed to have any meaning. Rarity struck him with the flogger, even landing a few lighter strokes across his balls – but those only made him cum all over again, semen backing up and forcing his balls to swell and swell to grotesque proportions. She knew just how big he could get and, although she was not quite as into the fetish as Fluttershy was, there was something delightfully alluring about a pet pony with beach-ball size nuts, was there not? There was no one there to raise a disagreement with her and Rarity giggled as his balls plumped up more and more, heaving with desire that was forever destined to be spent in the manner of ruined, wasted orgasms.

That was not her concern. He was there to be used and her mane fell out of its curls as she howled out her pleasure, needing the release, dare she say, even more than he did. Orgasm followed orgasm and Rarity held nothing back as she stomped and neighed, his body aching more and more from being pinned down in a single position for so long. It was not for him to complain, however, his muzzle shoved into a marehood and stinking still of urine, the reek of it curling into his nostrils even as some part of him wanted to curl back his upper lip to better sift through the scents in a feral manner. She prodded his balls, cajoled and teased, massaging them with her hooves as he shot yet another ruined orgasm, his nuts rumbling as they churned and groaned with need that would not be sated.

“Let’s see how big those nuts of yours can get!”

And she made it quite clear how she intended to do that, throwing her head back and laughing manically for the sheer hell of it, the release of tension all that she needed. Her marehood crushed down onto his muzzle, sitting heavily again on his face, and he had no choice but to lick, even though his tongue moved automatically by now, following the pattern of her lips there that made her feel best. He could tell, of course, in how she twitched and grunted, the tiniest of movements in her body feeding back to him just how well (nor not) she was doing.

Rarity, however, had one more trick up her figurative sleeve to truly debase him and it was the one thing that made his heart plummet, the mare hefting up an oversized dildo that was tapered to a point designed to pry open a hole that, perhaps, did not want to be stretched. If he’d seen it coming, Arctic would have fought and squirmed but the first he knew of the massive toy was the cold press of the lubricated toy against his doughnut, the fleshy, soft hole not quite tense enough to ensure that she would be denied, if only for a moment longer.

No!

Rarity squealed, ramming it in, forcing him open, the stallion’s head reeling.

No... But yes, oh, yes... No, he had no choice and he gulped and heaved for breath, eyes closed tight against the reality of it, his body trying everything and anything it could to close down against it, to force the toy out. That wasn’t his thing, not something that he enjoyed, but Rarity didn’t know what ‘no’ meant with a cute little toy like him and giggled wickedly, even lifting her hips, briefly, away from his muzzle as she took in the pained expression, mingling with humiliation, rising up heatedly on his face.

“Oh, Arctic... Colt. You’ll have to get used to it.”

And yet he didn’t think he ever would as he was forced to lap her again and again as she brutally sodomised him, angling the toy just so in a gesture of dominance that she forced him into his strongest orgasm yet. That didn’t mean that it felt good though as his head pounded, pain rising through, the ecstasy unwelcome in how abruptly it was cut off, a climax denied as his aching, pained tail hole strained to take it, the scar within complaining. His balls pumped up, heavier than ever, and even Rarity spared a small ‘ooh’ at the size of them, bigger than the largest beach ball, although she would not force him to orgasm any more, his cock aching and throbbing out against the ring. The diamond-tipped sounding rod was still, of course, buried in his cock and she spun it lazily, scraping his passage in a way that was both pleasurable and achingly painful, the resulting tingle drawing a short, harsh snort from his lips over her sex.

“Yes...” She hissed. “Oh... Oh, Fluttershy knew just how much I needed this!”

Leaving the dildo humiliatingly wedged up into the tail hole of a pony who could not, as yet in his state of arousal, take pleasure from it, she swung the flogger at him, considering it for a moment before tossing it away in lieu of a short, traditional riding crop. With the crop, she wickedly twirled it and directed him to face away from her, the white of his coat taking on a red hue in the crimson mood lighting.

“Ah... There’s only one way to finish this, colt,” she breathed. “And you’re not going to like it.”

It didn’t matter if he did or not and Arctic obediently braced and bowed his head in submission as she lashed his backside, marking him with welt after welt, the red, throbbing marks rising up angrily in response to the beating, sating a deeper, darker desire than the mare could, at least publicly, let out in the course of her work.

And she was a beast herself, feral and cursing, her ladylike demeanour gone as she cracked it over his balls, forcing him into another orgasm even as he stood there, howling out both the pain and the pleasure of it all. Maybe it was more than one orgasm too but neither of them was keeping count as his oversized balls shoved his backside up from the stage, hooves not even touching the floor. Only when Rarity was panting and heaving, flanks marred with dark sweat soaking through, did she finally drop the whip, the wild passion in her eyes tamed.

At least for the moment. Arctic was no fool as she settled her attire more comfortably around her body again, turning from him now that she was done, her marehood sodden and yet satisfied. He knew that Fluttershy would lend him out to Rarity again and again and it would be up to him each and every time to ensure that Rarity’s needs were seen to.

That was the position of a good pony pet, after all. And he knew he had to be a good little colt for Mistress Fluttershy. Everything had to be for Fluttershy, even when he was not with her, bearing through the unpleasant strain under his tail even for her will and pleasure above all else.

Rarity, however, didn’t spare him another thought, refreshed and motivation renewed.

“Clean up the mess in here before Fluttershy comes for you, darling,” she hummed, leaving the main boutique with a skip in her step. “And put the racks straight – I have a meeting with Fancy Pants at four on the dot and I simply cannot be late!”

Sprawled out on the floor, the hobble strained between his hind legs, balls forced in front of them, Arctic let out a long, low, pitiful groan. But the only answer he had for her was the one trained to his lips and it leapt there on light wings as easily as a butterfly would land in the breath of a kiss.

“Yes, Ma’am.”
