Author's Notes:

So I decided to write a quick little bonus for this story in celebration of it getting so many likes. All of which is based around some crackpot theory I had. Enjoy!

Twilight Sparkle wiped a joyful tear from her eye as she watched the scene from Ponyville town square. At long last, Equestria was back together once again, now stronger than ever. Around her, changelings and stallions alike worked to rebuild Ponyville to its past glory. Not only were the old abandoned houses repaired to a livable state, but also new ones added for the many new changeling inhabitants that had all been handed their permanent and official Equestrian citizenship papers. But their work was far from done with even that, as more structures and expansions were planned to accommodate for the large influx of sex slaves they were expecting from the lands beyond. Each new subjugated race would bring a new flavor to the table… one that Twilight could hardly wait to have her way with. Especially zebras… the thought of those striped and stripped mares lapping away at her pony pussy to Spike’s enjoyment sent a shiver down her spine. She would have to make extra sure her master had the appropriate funds to purchase one as soon as they became available to the public.

Walking around town, the alicorn was amazed to no end at all the changes her Ponyville had taken to that signaled the coming of a new and better age. Sex toy shops, mare disciplinary schools, slave sitting services, pounds for housing stray mares, and body modification services… all were new enterprises emerging from the jungle that was the free market… and with promising prospects to top it off. Perhaps one of her favorites was Ponyville’s group of resident changelings who ran a certified Mare Training practice, claiming they could take any plain freedom-loving mare and break her into a collared, cock lapping, and cum hungry sex slave in little under a half-hour. Though she had not personally witnessed their methods, she believed it. And with only the last few bits of Equestria’s female population still unaccounted for, they might have a bit of business left on their hands. The new Equestrian government had deemed those few remaining non-enslaved mare free game. Finders keepers, if you will. But they were bound to require some thorough breaking in and training as their stubbornness was likely to be the only reason they had made it this long on their own.

“OOooooh! Ohhh! This one, dad!” Twilight heard a young stallion squeal from a nearby pound window as he fondled and caressed the bare body of a slightly older and collared yellow mare sex slave on her hands and knees… who just happened to be up for sale to any potential owners. “Can we keep her? Can we? Can we? I promise I’ll take good care of her! I’ll feed her, and train her, and take her out for walks every day!”

“I don’t know, son…” The father replied. “Owning a mare is a big responsibility. Are you sure you’re up for it?”

Twilight smiled to herself as she walked away. The unknown and panting mare already nuzzled the stallion’s chest affectionately. She nodded her head in shared enthusiasm along the stallion’s persistent begging to his father while not speaking any words herself. In the end, the two of them eventually won the parent over. One handful of golden bits later the cheerful lad exited the store, whistling a happy tune. He walked along after his father, holding the leash of what was sure to be his first of many pony sex toys eagerly crawling after her new owner towards her new home.

Twilight’s attention was suddenly directed to her front as two arms wrapped around her in a hug. Under closer inspection, she discovered it was her mother pressing her bare breasts against her own in a deep embrace.

“Mom? Dad? What are you two doing here?” She asked, though not angered or annoyed. Simply surprised as she returned the loving hug.

“We just wanted to stop by and remind you just how proud we are of you,” Twilight Velvet spoke sincerely, unrelenting in pure hugging force. “You’ve done some amazing things for this land, dear, but helping the changelings easily takes the cake.”

“Thanks, mom,” Twilight said. It may have been a slight exaggeration on her part, on top of her past achievements that she played a role in… mainly saving the world. But, in a way, nobody really recognizes it when you save the world from an evil magic-eating beast or a nightmare creature from the moon. Their lives just continue as normal like before. But now, things were better for all ponies and changelings alike. It brought a warm fuzzy feeling to her, one that told her she had helped accomplish true good in the world that would last for generations. Her eyes shifted from her collared mother to her fully clothed father.

“We were actually just dropping by to visit the Ponyville hospital,” Night Light stated warmly. “Nothing’s wrong, of course. It’s some sort of new law put in place now that everyone is getting settled back into their old homes. Meant for any pony couples looking to have a foal. It’s a quick procedure but you have to go visit some medical changeling in an examination room. The Canterlot one was packed full of couples so your mother and I just figured we would come here and pay you a quick visit while we were at it.”

“I know about the new rule,” Twilight replied. “I have an appointment scheduled later today myself. It’s for Spike and I… Well… he’s not technically a pony, but the law still applies. I’m just wondering what exactly it’s for...”

“Oh, let the men wonder, dear,” Twilight Velvet scoffed to her daughter. “Us mares have better things to think about… Like how we can get a certain stallion’s pants off on the train ride home…”

“Opps! Guess that’s my cue!” Night Light beamed, planting a firm slap on his wife’s plump ass. The mare giving a delectable moan in response. “Best haul this horny lady back on home before things start getting too frisky again! Public sex is nice and all, but she is a screamer! Don’t want to risk alarming half the town!”

Twilight lovingly waved her parents off as her father dragged her mother away on a short leash. Taking one final moment to admire the splendor of what Ponyville was being converted into before heading to the hospital herself for her scheduled appointment. Tardiness was not something she took lightly after all…

“Come in, come in!” A changeling voice greeted Twilight warmly as she crawled through a newly installed pet door, fit for mares of course. The room was like she would have imagined a typical examination room to look like. Meant for one on one conversations, with a long examination table on the opposite wall end. “You can call my Dr. Cornicle.”

“Alright… Doctor,” Twilight said respectfully with a bow of her head, knowing she was in the presence of a male once again. The changeling’s eyes roamed over her nude body, taking in her true beauty in the typical changeling obsession they had become known for.

“Let’s just get you on up here real quick…” Cornicle said as he magically levitated the alicorn’s body from the floor, flipped her around, and lay her face up on the exam table. The pony knew not to struggle, even as the creature’s hands began to grope and squeeze at her monstrous swaying tits. Another of his hands fished between her legs, inserting its digits into her soaked folds. She couldn’t quite tell if it was all part of the medical procedure, or because the changeling wanted to. For either one it happened to be, she was okay with it.

“Now, have you been having regular intercourse with your owner?” Cornicle asked. “And you are here because you are looking to become pregnant?”

“Yes and yes,” Twilight replied obediently without the slightest hint of shame.

“Is he providing you with loving care and ample opportunity to nourish yourself from his cum?”

“Yes… he is…” Twilight said, though noting she could have lived without that chastity belt punishment.

“And do you, as a mare, perhaps think that you are meant for more in this world?”

“Of course not… I’m doing what I love and who I love and I’m free to express my love for others in ways that would never have flown over so well before you changelings came… I couldn’t be happier.”

“Good… good,” The changeling remarked as he noted down her responses. His horn began to glow a soft emerald hue as his magic fired up. “Now, I know you’re probably wondering why you’re here, Ms. Sparkle. Why this is a government mandated check-up and why it’s only for mares who are seeking to become pregnant.”

“Now that you mention it… I wasn’t going to ask, but I did actually wonder,” Twilight admitted, but saying so in such a way that hopefully did not convey she distrusted or questioned the law, or even that any shady business might be happening. She trusted the changelings with her life.

“I normally spare most women from the explanation, as they have better things to wrap their minds… and lips… around,” Cornicle spoke casually. “But after reading up on your file, Ms. Sparkle, and all the education you have gone through I think it would be best to explain it to you and the subtle change I’m about to make within you. Perhaps you could find a better way to phrase it for your fellow mares. *Ahem* To start… think back to the time before my kind changed your world for the better.”

“Okay…” Twilight nodded.

“Because of pony biology and the rate of which each gender was born, there was only one stallion for every three mares… And since, for reasons that escape my knowledge, your society chose to ignore the concept of polygamy and limited a single mare to be married to a single stallion. Because of this, all mares eventually developed bisexual feelings, as a contingency in the event they don’t find a male lover in their lifetime… Which was two thirds of them, if I am not mistaken. But you already know this much, don’t you?”

Twilight nodded sternly as the changeling continued on. She wasn’t ashamed to admit she was attracted to other mares… but that wasn’t to say she preferred their tongues or fingers over a hot throbbing cock any day of the week.

“Well, as cruel and unusual as the practice was on mares, it did actually have a strange positive effect on pony society… and I don’t mean driving us to invade and fix the problem for you, oh no.”

“Wait… it did?” Twilight gasped. From what she had heard, monogamy was a dumber idea than the concept of stallions… or so Chrysalis had so elegantly put it.

“You see, that one stallion is now placed in a rather powerful position when it came to choosing a mate from the masses. With so many mares to choose from, and so many eager to be chosen, he had the pick of the litter. More often than not, they would abide by their base desires, choosing mares with the most important features, from large breasts, shapely hips, thin stomachs, pretty faces, and submissiveness… That last one more so chosen after the courtship process began. Should any given female fail this initial visual review, they did not even make it to, as you ponies put it, the ‘dating’ phase, let alone marriage and impregnation.”

Twilight’s memories rushed back to early exchanges she had had with her mother. Even through all her books and studying, Twilight Velvet urged her to always make herself… ‘presentable’. To focus on her own appearance, to stay skinny and fit, not to mention to smile more when in the presence of men. Her brother on the other hand had received no such extreme advice from either of his parents… And he went on to nab a princess in marriage…

Now, statistically speaking, the best looking and best behaved mares had earned themselves a husband, and more importantly the ability to pass on those positive traits to their offspring. This is why, over countless generations of ponies, mares have slowly grown more attractive, more submissive, and all around better than those that came before.

During her time in the hive Twilight did recall hearing Princess Celestia and Luna conversing about how much sexier today’s youth was in comparison to those… who knew how many years ago! But she really hadn’t given the comment much thought at the time.

“Though irrelevant now, you should know, Twilight Sparkle, that even if us changelings never even existed, your Equestrian society would have eventually risen up to the male-dominated world it is today. Though it would have taken far too long for our tastes, personally. I think we can all agree; our way is better.”

“R-really? How exactly would that have happened?” Twilight asked, now full to the brim with utter curiosity.

“Well,” Dr. Cornicle mused after a moment of thought, idly playing with the mare’s privates as he talked. “let me phrase it like this… You have a friend in fashion, correct?”

Twilight nodded, though Rarity was more so strictly stallion and changeling fashion these days, what with mare clothing being banned.

“As I’m sure your friend will all too eagerly agree, fashion has evolved alongside society over the many years. The styles of old were bulky, cumbersome, and of course, covered a good deal of the female body. Meanwhile, in the present day, pony society was just about to adopt a more appropriate sense of fashion that went along with their base desires. Heh… imagine your Gala dresses, dipping a bit lower to reveal a surely harmless fraction more of your cleavage… Whatever it took to catch a stallion’s eye, right? Or, in a more casual fashion sense, visible underwear straps, bare midriff, nearly transparent tank tops, shorts getting shorter, showing even more of those delectable legs that a stallion could get his hands on if he chose to take you to bed… Well… you get the point. Sex sells, now more than ever before.”

“Well, I suppose that’s true so far,” Twilight nodded in agreement. Before the changeling invasion, when she still had the wrong outlook of how mares should present themselves, she had admittedly found herself appalled by the risqué fashion her fellow mares had taken to. Not the others in her group, but ponies as young as the CMC! None of which saw it as doing anything more than wearing something that was ‘comfortable’.

“But ask yourself… do you honestly know where the slippery slope would stop?” Cornicle went on. “None of us can see into the future… well, barring that one slut from the blue hive. But we could take hints from the evidence around us. Eventually we saw some hints of well-meaning mares coming along and claiming mares deserve the right to be topless because stallions have that choice. That tits aren’t a sex object… heheh, let’s be honest, your entire body is a sex object!” Cornicle chuckled as he patted the giggling alicorn’s stomach. “After that, I imagine it would only be a matter of time before fashion followed suit, covering nothing of a mare’s chest but her nipples, as for some unexplainable reason, you ponies decided that that was the point of embarrassment, not the rest of your breast. From that point on, it would only be a matter of time until a mare’s chest was completely on display. Not just from the few intelligent mares looking to bare their motherly assets to a potential stallion’s gazing eyes, but also from mares not wanting to be left behind… Dating was a fierce competition for you girls after all. The notion of willingly baring one’s own chest as a fashion choice would have appalled many before our invasion… but as our efforts have so appropriately demonstrated, mares will do anything as long as they think others are as well. It would be your hidden primal urges, pushing you, even on a subconscious level, to take the leap. Because at the end of the day, all women are just looking to find a cock that can rut a foal into their wombs!”

Twilight winced slightly as the changeling emphasized his point by roughly grasping at her gently swaying globes. Though it was nothing she had to be taught. The alicorn having long since learned her gender was destined to act as little more than men’s obedient servant and sex pets. To her, history was simply a way of revealing how much her fellow mares had struggled to come to that conclusion, reminding her once again how eternally grateful she was for the changeling’s intervention.

“Well, anyway,” Cornicle continued, “back to the present and the reason why you are here with me in this room. After the massive overhaul of pony society we are implementing, this ‘survival of the fittest’ aspect will no longer exist in Equestria. As all mares of all looks, shapes, and sizes are able to not only modify their bodies to a better appealing appearance, but also guaranteed they will be knocked up and give birth multiple times. Not just the most deserving ones handpicked by selective stallions with the most positive traits to pass on.”

With that, the changeling’s horn ceased its emerald glow, signaling the he was finished.

“Fortunately, we have been hard at work, using our changeling magic your fornication so kindly provides us to develop a new spell. A sort of genetic editing if you will,” he said, patting the spot on Twilight’s lower body where her womb was located within. “The effects will be invisible to you, of course, but this will ensure the best possible chances that your offspring, should it be female, would inherit the best traits you as a pony possess. Mainly your looks… but I suppose your brains could sneak into your foals as well. No more rolling of the dice. That’s the more complex usage of the spell, though… did you know it could also be used so as to ensure only mares result from pregnancies? Haha… actually, you might find it interesting to know Chrysalis once asked us to do exactly that to you mares… but in secret. She kind of has a thing for seeing stallions bred out of existence.”

“Yeah…” Twilight chuckled to herself. “I guess she did kinda hate stallions a bit. But I’m glad we were able to reason with her and talk her into seeing that they aren’t so bad.” She beamed proudly.

“Actually… Chrysalis gave us that order last Saturday,” Cornicle deadpanned.

“Oh………”

“But don’t worry! We didn’t listen to her. Stallions are our allies after all! We aren’t too full of ourselves to admit we need as much help as we can get to fuck our way through the moaning masses. By which I mean you women, by the way.”

“Hehe,” Twilight giggled as her naked body was levitated off the examination table and back into crawling position on the floor. “Well thank you, doctor. Not just for this… but for everything,” She cooed, nuzzling up against his leg seductively. “Stop by my- I mean, Spike’s crystal castle if you’re ever in the mood to let me repay you personally.”

“I might just take you up on that…. And it’s no problem at all, my little pony. It’s just what we do.” The changeling smiled back before planting a gentle slap on the alicorn’s purple rump. “Now go on and scamper that nice ass of yours back to your owner! I’m prescribing at least three creampies a day until you get knocked up with a beautiful healthy little foal. And send in the next mare on your way out!”

“Three creampies a day? That’s child’s play,” Twilight laughed to herself as she crawled back out through the pet door. As she traveled back to Spike she knew, even if she had known it before, that not only her but all the inhabitants of Equestria had a bright pleasurable future ahead of them!
