Mayor Mare positively vibrated in her bindings, the tight leather outfit covered nearly everything. She couldn't see, she could hardly hear, and nearly every inch of her fur was covered save for her teats and a wide expanse around her holes and belly, for obvious reasons. Though she was initially disappointed they covered her mouth entirely, something about being bound so completely made her feel aroused.

Not much had changed for the ex mayor after a hundred years serving as Celestia’s toy and broodmare. She lay bound like she usually did in some featureless white void under what she assumed was Canterlot Castle. An endless parade of cocks, births, and nameless males had taken their turn with her and she had pleasured every single last one of them to the absolute best of her abilities, faithfully devoting herself to their service as if they were Celestia herself.

An act of loyalty her god rewarded.

She had birthed enough foals to start a small army, enough monsters to repopulate the Everfree and a small contingent of creatures she had didn't even know the name of. She had been impregnated by many different sires at once and even contained a squirming mass of twenty seven young at one time. Truly she had fallen into her new role with an enthusiasm the princess had never seen before.

You would think that, after a hundred years of near constant sex, things would grow dull, but her adaptable body seemed to revel in each new depravity with virginal enthusiasm. No matter how many times Celestia squeezed her perfect cock into the mare’s body, Mayor Mare came the moment it was inserted.

Her body had not grown old, and after she got used to her new form she never truly tired, going from one cock to the next and simply burning love to stay standing. Love or lust worked wonderfully for this purpose and Mayor Mare had made a game of it this past decade - staying up day and night, always ready to service a new cock or witness the birth of her newest litter.

She had been bound in leather and bolted to an iron horse, making it impossible to not spread her legs while giving anyone access to either of her holes. Not like this was necessary, mind you - she hadn't put up a fight since the day she first woke up here, but Celestia seemed to enjoy it and the bound mare had come to love the feeling of surrender that came with the heavy bondage.

It had been over an hour since someone had come to speak to her and they had only briefly mentioned the fact that Celestia would be arriving with a guest. Mayor Mare couldn't ask who it was... not like she would anyway, as that didn't matter. She couldn't help but be a little curious, though.

She had only ever entertained foreign dignitaries a few times and, though the experience had been pleasurable for all parties, she always felt nervous when it happened. Judging from the odd mix of emotions coming from the pony that had come to tell her the news, she knew right away it was some foreign individual of great import. She couldn't really explain how she knew, but after all these years her senses had been honed to a razor point and she knew instinctively what the pony had left unsaid.

She also knew that whoever or whatever this foreign male was going to be, they were large. Her legs had been spread far warder than usual and the space around her holes had been cut exceptionally wide. In addition to that, the space around her belly that was left bare was huge, as if they expected her womb to be filled to enormous proportions. All of that led the mare to her current predicament.

She was ecstatic at the surprise, but there was a deep hunger gnawing in her belly. She craved what she knew was coming and the possibility of servicing someone new was beyond arousing. She was thrilled by the potential despite the lack of stimulus, her senses pushed as far as they could go, desperate for any hint of change in her environment.

Her nose twitched and she breathed in deeply, inhaling a deep lungful of a strange, almost spicy scent. Whowever this was, they were powerful and not from around here - she could smell the scent of foreign soil on him, but she couldn't place from where, which was surprising as she could usually tell where a pony was from based solely on a single sniff.

Next came the potent cocktail of emotions from right in front of her. Instantly she recognized the absolute calm of Celestia, marred slightly by her assistant’s nervous apprehension. Beside them was not the usual confusion tinged excitement that Mayor Mare had come to expect from the new individuals who came to meet her. No, this individual was nearly as calm as Celestia and had almost the confidence to match her.

The electric door slid silently into the wall, only the near silent swish of its departure alerting the mare to her visitor’s arrival. Mayor Mare blinked beneath her blindfold, confused. The deep thudding footsteps of the visitor were not merely a trick like she had first thought, and indeed, even now she could feel the thump of her visitor’s thick feet hitting the ground.

From the vibrations alone she knew the visitor lacked hooves, his steps had the slapping sound of non hooved feet but they were far heavier steps than what she had felt before. The sound of Celestia snickering drew a smile to the mare’s face and she already knew what her goddess was about to say, as she had used the same line many times before on her new visitors.

“Love at first sight, isn't it?” She quipped.

The visitor chuckled in return, not put off in the slightest by the image of the bound mare. “I wouldn't go that far, but you certainly have me intrigued, Tia.”

The voice was deep, far deeper than most other visitors and it belied a confidence that Mayor Mare could taste. She had a pretty good idea of what kind of creature this new visitor was and referring to Celestia as Tia was another solid clue.

This visitor didn't waste time, however, and he strut around the mare, looking her up and down with a critical eye. Mayor Mare tried her best to look appealing but she could hardly move, which made the act of looking attractive a little difficult. Even then, she could feel the soft bloom of arousal coming from the visitor, tinged by an undercurrent of potent lust and… frustration? Guilt? She wasn't sure.

“And you’re sure she can take me and carry my young?” The visitor asked, his confidence wavering.

Mayor Mare could all but hear Celestia’s eyes roll. “Yes, I have told you a hundred times, she can bear the child of any creature native to Equestria, and a few that aren't.”

The visitor snorted. “I know, but to think a mere pony, even a hybrid, could contain an entire clutch of my children is… odd.”

He continued circling her, his unease beginning to wane as well as his uncertainty. Celestia stopped him suddenly and spoke in an odd, almost concerned tone of voice. “She can handle a lot, but don't cut loose too much. She has proven valuable over the decades.”

The beast seemed to stop and waver for a moment. “Is that reluctance I smell?”

Celestia took a step back. “No, she is a worthy tool that I would hate to see broken.”

There was a long silence that was finally broken by the visitor chuckling and turning away. “If you say so, Celestia.”

The alicorn breathed in a little deeper, the way she did when she was annoyed but refused to let anyone know just how pissed she truly was. “Let the staff know when you are done with my pet. I have more important matters to attend to.”

Then, in a flash, the alicorn was gone, leaving the bound mare in the room with her visitor and the aide. The male chuckled darkly and prodded the mare’s side. “Anything I should know before mating with this one?”

The aide shook her head vigorously. “N-no. Mother is a very kind and generous lover. Now if you will excuse me.” The aide scampered off before the visitor could respond, leaving behind a trail of embarrassment.

The large visitor shook his head. “Mother? Such odd ponies down here, and the tone of her voice seemed to imply…” a brief shudder ran through him.

He turned towards the bound mare once more and she immediately perked up, knowing instinctively without even the use of her eyes that he was staring down at her. Celestia’s odd outpouring of love aside, she had a visitor to entertain. And though a part of her was still celebrating the small bit of pleasure she felt from the attention of her goddess, she stuffed it down for now. She had work to do and a new brood to eventually birth.

The visitor seemed to feel the same and he quickly rounded the mare one last time, stopping behind her and sniffing her dripping entrance. The faint tingling she had been feeling for a while ballooned to encompass pretty much the entire space between her legs and up to her midsection. Clearly this visitor was larger than most and her body was rushing to adapt in time.

It was not fast enough, however, and the visitor suddenly lurched up onto his hind legs and fell down on top of the bound mare’s prone form, utterly smothering her. He wasn't the largest creature she had ever mated with, but he was easily the largest where it mattered, and in that regard he was truly an impressive specimen.

His endowment was resting along the mare’s back, lying between her large, perfectly round pair of soft cheeks. He was easily as large as Celestia, if not larger, but where the alicorn was impressively wide and had a fat, flared head, this visitor had a knot the size of which would stretch her cunt to even its impressive limit. Stranger still, though, was the fact that she felt something else - though he had settled his weight over her, he held a little further up than males usually did.

Which may not sound like something worth being curious about, but the mare had been bedded thousands of times and every small and subtle movement from her would be lover was known to her, and something about this one led her to believe that he had a surprise in store for her. The visitor settled in nicely, finding that he was just large enough to comfortably drape his entire body over Mayor Mare’s with room to spare.

He wasted no time in his movement and, after finding a comfortable spot, he immediately shifted his hips back, his deceptively heavy cock dragging down the mare’s back and down between her ass cheeks, drawing a shiver of anticipation from the mare who pushed her ass up, angling her holes for a more easy access. This in turn seemed to speed up the visitor’s pace, a small bit of reluctance seeming to blow out of him. Perhaps he had been worried if it was consensual or if his partner was going to move; whatever the reason, he had gotten over it quickly and, with a surprising dexterity, he suddenly drove his hips forward.

Her shocked gasp of surprise was muffled to little more than a strange eep and she quickly realized what the visitor’s surprise had been. Where she had expected to feel the sudden jab of a single cock, she felt the dual press of two insistent dicks. Her experience proved its benefit once more, though, and she was somehow able to angle herself in such a way that both heads slipped inside her with only a single moment of delay.

Despite the surprise, his twin lengths quickly sunk into the mare through a combination of the excessive amount of feminine juices that served as lube and a brutal and uncaring pace set by her visitor. She couldn't fault him, however, and rather than be put off by his insistence, she saw it as a challenge and, even as her first orgasm came rocketing to the forefront of her mind, she still focused on him and the continued tingling inside herself.

A sudden thrust and several more increasingly difficult inches slipped inside her, his dual lengths were growing much wider the deeper he went, and even her expert body strained to contain it all without tearing under the pressure of it all. Somehow, she was able to adapt and she grit her teeth in concentration. It was slight, but she was able to stretch her cavernous cunt more and more, though it felt more like running in front of a train than the usual slow adaptation that she usually underwent.

His pace was manic, as if he was being timed or something. Mayor Mare pushed those thoughts from her head; she needed every drop of concentration on willing her body to shift faster, wider and wider still. To fail here was not only to bring pain on herself, but to bring shame on her goddess. Celestia had entrusted his pleasure onto her and she would not leave him wanting, no matter what.

Even her grunting visitor was surprised when her hips abruptly pushed back against his own, allowing a few more inches of his cocks to press inside her. He was deep now, nearly to her womb and, from the thickness of his cocks, she still had a long way to go. But she was confident, cocky even, and she knew she could take every last inch. After all, if Celestia trusted her to bear him a brood then she surely could, right?

The visitor didn't hesitate for long, however, and his brutal pace quickly resumed. Even with Mayor Mare’s confidence and the visitor’s strength, they were quickly reaching a wall that refused to move despite the mare’s insistence. She had steadily grown tighter the deeper he had gotten and, despite the fact that she knew her body could take the abuse, she was just too tight to make it pleasurable for her newest mate.

The male stopped and pulled back slightly, grunting in pain. He snorted a hot burst of air across the back of the mare’s neck and she couldn't help but feel like she had failed despite the sheer physical impossibility of what she was trying to do. She desperately wanted to see her belly right now; her astute senses told her that she had been stretched well beyond what she had experienced in decades and her belly was no doubt distended by the massive size of the visitor’s cocks, a sight she wished she could see.

She had always felt a certain pride at the sight of her horribly distended belly that could barely contain her lover’s endowment. She couldn't revel in that pride, though, his insistence that was at first childish had taken on a more sinister edge, and the mare was suddenly aware of a small ember of anger burning within her mate. The hot breath across the back of her neck could have easily been a fire so powerful that she could have been made into nothing more than ash in a moment’s notice. The weight on her back that she had enjoyed could easily crush her and the razor sharp claws that were just beyond her reach could rend her asunder in an instant.

She gulped, suddenly aware of just how mortal she truly was. Sure, she was filled to the brim with love, but what could she really do in the position she found herself? With a new sense of urgency filling her, she threw herself into the motions, pouring love into her adaptability and praying it could catch up before he lost patience with her.

The visitor had grown urgent, pulling out and ramming himself back in every few seconds, trying to batter down the wall with brute force. With every powerful thrust, the mare couldn't help but wince - his size was beyond anything she had encountered in her lengthy career and this was proving to be a challenge she may not be able to top.

With their combined efforts, they managed to squeeze a few more desperate inches into her, but she could tell that such a strategy wouldn't last long against such a monster. He was just too large and even her with almost perfect record she knew this night would end with a distinct feeling of failure. She didn't let that get her down, though; despite his size and her body’s inability to take the entirety of him, she could still get him off and fulfill her purpose.

So she moved away from her desperate attempts to fit more of him into her now thoroughly wrecked cunt and instead redoubled her efforts on milking his cock with everything she had. Strategies and methods cultivated by a hundred years of practice were suddenly employed, leaving her lover shocked, his body suddenly stock still.

Her pussy squeezed down on him, alternating from base to tip and vice versa, all while she rocked herself back and forward. Smaller, more subtle methods such as moaning whorishly around her gag and rubbing her beautiful ass against his soft underbelly were also employed. She even began to use the changeling aspect of herself to its full use, throwing off a potent mix of pheromones designed to put a heat in any male or even female creature’s loins.

The pheromones did their trick in seconds and her mate began to buck his hips wildly, lacking any clear rhythm or even a poor attempt at one. Passion drove his body, making it difficult for anyone to match him, but she was more than capable of rising to such a challenge and her carefully honed body sensed his wild passion and pushed back against him. His erratic thrusts were somehow being met with perfectly measured responses from the mare, and their hips met with a rhythm that belied their intense lust.

His cock battered through her womb, a small jet of hot pre allowing his member to slip through unopposed. Gone was the semi-composed visitor that she had met early, her finely tuned pheromones reducing him to a growling animal, devoid of thoughts. The knowledge of his state should have made her fearful - he was working on instinct now, not planning, and this side of him would no doubt feel no guilt in butchering her. She was not fearful, however; quite the opposite.

She knew that such an animal was easy to control; she had mated with hundreds of animals over the years and knew instinctively how to curb their aggression and guide it to a more pleasurable direction. Minutes passed and his bestial lust continued unabated, even as his cock slammed into the opposite side of her womb he still thrusted with the same power and ruthlessness that he had from the first moment she had hit him with her pheromones… though she could tell he was beginning to slow.

Her body was simply too small for what he desired and his knot banged into the entrance of her pussy insistently. She knew right then and there that taking its bulk would be impossible and, rather than push herself too far, she doubled down on her techniques. Rewards were just around the corner for the bound mare and her talent was more than enough to make even the bestial visitor to moan aloud.

She could sense his release and felt his cocks begin to twitch erraticly, adding to the already overwhelming sensations assaulting her cunt and driving her to another orgasm. Her pleasure was merely an afterthought, though, and hardly paid it any attention at all. He was all that mattered; his cock, his cum and the promise of being impregnated yet again. It was her reason to exist and it consumed her.

It didn't take long for the visitor to slow even more, his frantic state beginning to ebb as his orgasm came closer. Out of nowhere, Mayor Mare felt her mate’s balls clench and potent seed begin to erupt into the depths of her womb. The visitor’s sperm was hot and sludge-like, filling her slower than most of her guests, though it did so more completely.

She had hardly even heard his roar of victory, so focused was she on milking him for all her worth. It was the moment of truth and it all came down to this. She needed every last drop he had to give and, though she knew even a dollop of cum could knock her up with a whole belly full of children, that wasn't enough for the slutty mare. She needed to be filled, to take every last drop he had to give and empty the enormous balls she had felt touch her hind legs.

However, even that goal seemed outside of her reach and she quickly felt her womb becoming fuller by the second. This in itself wouldn't be overly concerning, but from the way his body twitched and his cocks moved, she knew he was only just starting and her womb had already become packed full of the strange, thick seed.

Her belly grew until she felt real pain for the first time in years. Again her body failed her - she couldn't accept his unearthly load and she whimpered patheticly. Failure after failure began to weigh her down and, for a second, she thought this might be a fitting end for her career. But the universe seemed to have something else in mind for the broodmare and, when her womb grew so packed that the pain had grown unbearable, cum began to slip past the twin members resting inside her and out of her abused hole.

Hot sperm dripped from her well-used cunt and the visitor’s semen pooled beneath her legs, gathering in a steadily growing puddle. She hoped Celestia wouldn't be too disappointed in her - the last time she had gone without the alicorn’s cock for nearly a year had been the worst time of her life, second only to the pathetic, worthless existence she had been in before Celestia had taken her and changed her body.

No matter how dark things might seem, they had nothing on those decades that were devoid of Celestia’s love. The void took her suddenly and, for the first time in a long while, the mare slept soundly, her hooves instinctively reaching down and cradling her massive, cum-filled belly.

Celestia looked down on the mare with a gentle smile on her lips. She had just deposited her toy on her small bed, something the mare had insisted on even after Celestia had offered her something nicer. The alicorn reached down and wiped a few stray hairs from her face before taking a step back and wiping the giddy expression from her face.

She did that just in time for a now very exhausted dragon to lumber in, and an air of utter satisfaction to blow in with him. The drake sighed and smiled goofily at the mare. “Thanks, by the way. It’s been far too long since I found a mare capable of taking as much as she did. If you ever need anything, just let me know.”

The alicorn smiled faintly and turned towards the green and purple dragon. “There is no need for such an offer, but it’s appreciated just as well. I know you had been feeling down recently and just happened to know someone who might be able to help.”

The dragon’s smile drooped. “Ever since Sweetie and Rarity…” he gulped. “I just never thought there would be another mare for me.”

The alicorn fixed him with a surprisingly stern glare. “She is not yours, young Spike. I know you’re getting into your hoarding years, but-”

The dragon backed up defensively, raising his hands in submission. “Alright, alright! Jeeze, Celestia. When did you get so protective?”

Her subtle smirk quickly spread across her lips. “Ponies change, my friend. Even me.”
