A Princess' Desire

A Princess’ Desire

“The play was simply divineeee~”

“I know, I know! The way the main actor conveyed Douglass’ character, ambitions, and feelings was a work of art. A work of art I tell you!”

“We cannot forget to mention the role of Azziccio. So much passion! That investment! I cried when he died at the end.”

“Quite.”

“Indeed.”

The snooty, nasal voices of noble mares gossiping reached Luna’s ear. Not that it was a particularly hard thing to do. Considering the usual loud, obnoxious, borderline annoying volume the nobles tended to use when gossiping, just to make absolutely sure those around them heard them clearly.

But Luna didn’t mind that. She held no love for the nobles, as most were an active detriment to Equestria’s ruling elite, at least in her opinion. But she had learned to understand that as long as they didn’t do anything too stupid and actually did their work, and not just pay it lip-service, they were useful and necessary.

What she did mind was the fact that the three noble mares had a servant at their side. Or rather put, a slave. Two stallions and a mare stood next to their masters; all of them showcasing a familiar-looking buttplug tightly nestled inside their assholes, a standard regarding pets, in all honesty.

Luna sipped on her tea, pretending she wasn’t glancing at one of the noble mares lowering her cup of coffee while her pet panted. The stallion, smiling and drooling, approached the offered cup, but instead of drinking from it, he neared the flaring tip of his member to the half-full cup. With a groan, the stallion released jets of potent white cum.

Most of it landed either on the table or the ground, though some did make it inside the cup of coffee; his added seed enough to fill the cup a quarter more. The noble mare lifted the cup back up before her, used a spoon to stir it up, and then took a sip.

“Most excellent as always, Tin,” the noble mare praised.

“T-Thank you, my Mistress,” the stallion replied in between moans.

“He surely is messy, isn’t he?” Another noble mare said with humor in her voice. “Cocoa, clean our table.”

“Of course, my Mistress,” the single mare among the slaves bowed her head in respect before she began licking and slurping all the leftover semen with vocal gusto.

Luna couldn’t take it anymore. She stood up, threw more than enough bits to pay for her tea blindly at the table, and left without saying anything.

As she walked through the familiar roads of Canterlot, she couldn’t help but notice how used she had grown to the new sights across the street.

Mares, and some stallions, wearing leashes, chained, and forced into positions that ensured they were exposed… and free to use by the passersby’s. All the while their masters or an actual servant kept an eye on them. Usually, these slaves were there in the ‘Shame Stocks’ because they did something wrong or disobeyed their masters.

Many more were walking around the street alongside their owners; carrying them, their bags, or serving in whatever disgusting, humiliating, thrilling way their masters could think of. Recognizing a slave was rather easy. If the often fetishistic clothing didn’t give them away, then a collar, a leash, and the trademark butt plug widespread by Princess Twilight Sparkle herself were almost universally present in every slave.

Luna stopped for a moment to see a pair of slaves walking beside their snobbish master. The stallion showcased absolutely no shame in parading the two pregnant mares around like trophies. The mental image of her own heavily pregnant sister, the first legalized slave, made itself present for a moment or two.

Shaking her head, Luna snorted before resuming her stride towards the castle.

**********************************************

Luna walked through the familiar halls of the castle for several minutes whilst being escorted by four Royal Guards. When she reached her destination, Twilight’s chambers, she turned to the guards.

“Thank you all for escorting me, guards. You may return to your duties,” she thanked them gifting them a gentle smile.

“Ma’am,” the four of them replied, leaving but a moment after.

Luna closed her eyes and took a calming breath. She raised a hoof, hesitating for a few seconds, then she knocked.

“Who is it?” Came Twilight’s voice from inside the room.

“It’s me, Luna. May I come in?”

“Oh, Luna! Of course. Come in,” Twilight said a moment before her bedroom doors opened on their own.

Luna entered the all too familiar room to find it exactly as it always was: organized and spotless. Besides Twilight’s luxurious bed near the corner, a pile of hay big enough to accommodate two large ponies -- or a fully grown alicorn, Luna thought licking her lips -- laid with two large bowels next to it. One containing some water, the other was empty, but she knew it was used to hold food; fruits, vegetables, and some hay, usually.

Unlike other times, Spike wasn’t laying on the bed doing some work or reading a comic book like she usually found him. It was funny, and a little bit touching she had to admit, that despite having his own room, Spike slept alongside Twilight just to keep an eye on Celestia… and their soon-to-be-due offspring. The white alicorn had become as much of a pet to Spike as she was to Twilight. Though the lavender alicorn didn’t mind one bit. If anything, she found it arousing.

Shaking her head, Luna turned to Twilight.

“Pray tell, Twilight, where is my sister?” Luna asked while Twilight invited her to sit down across her work desk. Sitting down, Twilight answered.

“In the garden. Spike wanted to the one bathing her this time,” Twilight answered with a sweet little smile forming across her lips.

“Ah…,” Luna replied knowing full well what that meant. “Well, Celestia always said to love the royal garden. So I guess getting hosed in the open would be something she’d like. Not like it would be worse than all those other debauch… raunchy… immoral acts she has performed over the past year,” Luna said, struggling to keep the corners of her lips from curling up and her cheeks to blush.

“Ahhhh~ It has been quite a wonderful year, hasn’t it? International relationships have gone better than ever, though some work is still left to be done. No thousand-year-old or obscure villains and terrors have returned to threaten Equestria’s peace, the Tree of Harmony is stronger than ever, the magic of friendship is spreading across the land and beyond,” Twilight let out a content sigh. “Truly, we are entering a new golden age, don’t you think so, Luna?”

“Yes, yes. Quite,” Luna cleared her throat. “L-Look… Twilight… I--” Luna was interrupted when her sister landed on the balcony of the room. On her back was Spike holding onto her leash.

Luna watched Spike spread his wings to hover in front of Celestia. The tall alicorn didn’t walk unless Spike pulled gently at her leash. However, her eyes widened upon seeing the practically glowing aura her older sister was giving off by merely standing. It wasn’t her usual motherly, powerful, dignified aura. This was a much more primal, simple aura.

The aura given by a proud pregnant mare.

And pregnant she was beyond doubt. Her stomach was bloated, her already bigger-than-average teats had easily doubled in size full with milk, with the piercings and tiny bells still attached to her nipples making a soft tingle with each of her movements. Her fur was still well-kept, though it certainly lacked its previous opulent shine given by expensive tonics, shampoos, and whatnot.

No longer were there marks of what little make-up she once used staining her face, her tail was trimmed and held into a bun, just like her mane, to expose her nethers to the world. Her buttplug was there along with a seal across her snatch bearing Spike’s symbol.

“You may speak freely,” Twilight said without looking at the tall mare.

“Thank you, my Mistress,” Celestia replied bowing her head to Twilight. Then, she turned to Luna. “Luna, so good to see you!” She exclaimed before coming over to her little sister in order to nuzzle her.

Luna returned the nuzzle before replying. “Thank you, sister. It warms my heart to see you in such good health,” Luna said while stealing a glance of Celestia’s turgid belly. “Twilight and Spike have taken good care of you, I see.”

“Of course I’m going to treat right my foal maker!” Spike chanted before approaching Celestia. The dragon nuzzled and caressed her belly with love. “These are going to be the first of many, many foals! Celestia looks simply gorgeous with that belly, so I’m going to do my best to keep her looking like that! Oh, and to help propagate the Equestrian kirin population, of course,” Spike declared as he rubbed one of Celestia’s teats. Casually, Spike reached down just for long enough to wrap his mouth against one of her nipples and suckle on it for a few seconds. “Ahhhhh, so refreshing. Delicious and sweet as always. Mom and dad are going to have so many grandfoals,” he chuckled at the idea.

“Of course, Master. I shall grant you as many foals as your desire,” Celestia said in a solemn, elegant, submissive tone.

“Just like the fucking cow she is,” Twilight said, her entire body trembling in excitement with a small sadistic smile. “That’s all you’re good for now, aren’t you? Aren’t you~? A simple broodmare waiting to be impregnated again and again, ain’tcha? Who’s a good pet? Who’s a good whore?”

“I am! I am!” Celestia replied while Spike, his cock now hardening, climbed behind her. Celestia let out a little whine of pleasure as the dragon plunged himself inside her perpetually aroused cunt. Within seconds the dragon was pounding the alabaster alicorn with wanton desire while she moaned with each thrust.

Luna swallowed hard. Not even a year ago she would’ve had gawked (and she had!) at such a degrading, immoral scene. And even then she would’ve never put her sister as the protagonist of such. But here she was, seeing her sister being pounded by Spike. A scene that had, if anything and much to her own shock and initial disbelief, grown accustomed to. Or at least as accustomed as her dwindling morality would allow.

Even so, she couldn’t help but focus on Celestia’s expression. She looked so… content. Happy. Beatific.

Fulfilled.

Luna forced herself to look at Twilight despite Celestia and Spike’s background noises.

“As I was saying. Twilight, I wanted to talk to you about something... I am sure you garner what it is about,” Luns, steadfast, proclaimed. There is no point beating around the bush, as they say.

“I can imagine,” Twilight stopped working entirely on whatever she was preoccupied with before. “Tell me, have you noticed the mood around Canterlot?”

“Quite. It is difficult to not notice such eventuality,” Luna replied with a little blush.

“And like the laws I’ve written, everypony involved is perfectly happy!” Twilight clapped her hooves together cheerfully. “The slaves are protected by law as well as their owners. The Contract ensures concent, security, and clearance for all parties involved and it can be terminated the moment the slave says ‘Stop’. It is an entirely willing process, so you can put any doubts you may have in mind. I assure you, Celestia is being taken care of and the moment---”

“N-No. That’s not what I wanted to talk about, per se,” Luna shuffled on her seat.

“...No?” Twilight asked, genuinely taken aback. “Then… what is the issue if not that? I always thought you didn’t approve of it…”

“I… I don’t… but at the same time, I don’t oppose it. It’s… it’s a complicated feeling,” Luna replied with a heavy sigh. “I don’t much about the Contract or the laws and the impact it has had on Equestria behind it outside what I’ve seen around Canterlot.”

To their side, Spike groaned as his pace increased alongside Celestia’s moaning and drooling.

“Hmmm,” Twilight tapped her chin a couple of times before replying. “It’s not that widespread yet, and the more puritanical and old-fashioned ponies aren’t quite accepting of it as a whole. Surprisingly, many earth ponies have been speaking back against it, though it is mostly on the fringe villages and minor cities. With the exception of Ponyville. They integrated the Contract almost as much as here on Canterlot. But the nobles and the higher society have taken in the Contracts in full swing! Who knew they’d be so eager to legally own a pony?” Twilight giggled for a moment. Then, she blushed and let out a romantic, lovely sigh looking at the climaxing Celestia. “Some of us only needed a little push to find the correct way of love~”

“...” Luna said nothing while she saw Spike pull out of Celestia, wads of their mixed juices landing on the floor. Spike flew in front of Celestia presenting his semi-erect shaft; the mare immediately began sucking and lapping at the drake’s member until it was spotless. After that, she turned back and lowered her head to lap at the recently created mess. All the while she had a clear view of her sister’s well-used nethers, swinging teats, and gravid belly. “How far is she?”

“Almost eleven months. She should be ready to give birth to my first batch of nephews or nieces any day now! Ohhhh, I’m so excited!” She then used her magic to pull Spike close to her, hugging him tightly and smooching his cheek. “You’re the best little brother ever!” The dragon chuckled with a blush appearing across his cheeks.

“So, Luna, if you aren’t against the Contract and you’re not here worried about my Celestia, whatever is worrying you?” Twilight asked letting go of Spike.

“I’ve been thinking, Twilight. I really have… for a long time now…,” Luna closed her eyes in an attempt to fight against the deafening drum of her heart. “And I have come to ask for your help and to tell you that I finally made up my mind,” the Goddess of the Moon opened her eyes reflecting nothing but conviction. “I want to become a slave…”

Twilight, Celestia, and Spike were left speechless at her proclamation. The first to react was Celestia.

“Lulu!” The huge alicorn wrapped her forelegs around her sister and kissed her repeatedly, uncaring that she was staining her fur with each kiss. “You won’t regret it! Being a slave is so liberating! There is nothing quite like it!”

Spike sat there, amused, while Twilight smiled in understanding as she conjured a piece of parchment. “That’s enough, bitch,” Twilight ordered. An instant later, Celestia was on her hooves again, standing steady and eager as always. “Here, Luna. Be sure to read it as many times as you need, and when you’re ready, if you are after reading it, you can sign it,” she passed across the desk the parchment to the ex-princess of the moon. “But remember, after you sign it, if you want it to stop, just say so and that will be all,” Twilight clarified with a sincere, gentle smile.

Luna reached for the parchment, opened it, and then began to read it. She read it twice, thrice, seven times. She read it until she had ironed out every single possible loophole. Memorized every single detail. Deciphered how the rules could be bent or reinterpreted. And only when she was satisfied, she took the enchanted quill Twilight offered. She pinched her upper foreleg for a single drop of her blood, read the Contract once more for good measure, and only then she signed it.

She returned the Contract to Twilight. She too signed it without hesitation, rolled it up, and then conjured it out of sight.

“Welcome home, pet,” Twilight smiled at Luna with a dark twinkle in her eyes.

“I am home… Mistress,” Luna replied bowing her head.

Is it wrong that my heart skipped a beat? Luna asked herself fully aware of just how futile and worthless that question was; her already drenched and winking marehood provided the obvious answer.

************************************************

Master and Slave Contract Rules and Guidelines.

This contract, magically sealed and enchanted, is of full legal and social validity regardless of gender between age-abiding adults. For its validity, it requires the signature of the two involved parties, that is the Master and the Slave, signed via an enchanted quill necessitating a drop of blood from each party.

Upon signing the contract, it is the Slave who has the sole and unique power to end the dealing at the time he/she wishes to end it with absolutely no repercussions nor ill-binding consequences and shall once more be considered a free pony/creature. Upon release, the contract shall destroy itself and inform guard, legal, and justice systems for immediate action should it be necessary.

In the unfortunate case that one of the involved parties perishes due to tragic or natural consequences, the contract shall also be destroyed and measures shall be taken to terminate any and all legal leftovers and proper investigations shall be carried.

Therefore, it must be said, that during the existence of the contract, simple yet strict rules must be followed as listed below.

A Slave is no longer a free, normal thinking sentient creature. It, willingly, becomes a thing. An object. A PET. It will lose all rights given by the Nation of Equestria to its citizens, but in turn, gain those of a Pet, as per instructed by the Contract.

A Slave is to obey every and all command given by the Owner, unless it is an order to bring bodily harm to others, life-threatening actions to one-self, or demands so vile and repugnant that are either banned by law or simply goes against the morality of the Slave.

Excluding the previous exceptions, should a Slave disobey, reinterpreted, or be found lacking when performing the orders of the Owner, the Owner may punish the Slave as he/she sees fit.

A Slave is not an actual slave but a Pet and should be treated and seen as such. If the Owner only desires to own a Slave is to use it as free labor, then the Slave has all the right to report the Master. Labour should be done by employees or actual servants, not Pets.

A Master must provide shelter, medical care, sustenance, and commodity to the Slave at the very least at the basic level but never in such a way that a normal citizen would expect. Meaning, no luxury goods except for those to enhance the pleasure of the Owner him/herself. No complex food is to be given to the slave; proper food is for proper ponies, Slaves are things. Same for bits; money is given to citizens for their jobs, Slaves are Pets and banned from working as anything more complex than the pleasure objects of their Owners.

In the case of impregnations, the children shall be considered fully-fledged citizens. The Slave, wether be the mother or father, shall hold no claim nor relationship with the children unless the Owner permits it.

Should the case present itself where a Master wishes to give away a Slave to another Owner, the Contract must be re-signed and the Slave in question must agree with the procedure. The same rules apply after the transfer.

For further questions and clarifications please contact the Chamber of Law and Order in Canterlot or any of its Branch Offices in the Major Cities and Townhalls in villages. Signatures go in the dotted line below.

That was the entirety of the Contract Luna had read and sighed just day prior. Now she stood in Twilight’s private dungeon after spending the remaining of yesterday’s afternoon with Celestia. The alabaster alicorn spent most of that time giving Luna tips, warnings, and quite simply proclaiming the virtues of being a Slave.

So, here I am… after seeing my sister’s happiness and that of many Slaves across Canterlot I finally mustered up the courage to actually do it. Heh, it almost sounds like a bad joke. From Princess to commoner to willing pet with no rights and expected to be entirely subservient, Luna thought while she waited for Twilight’s arrival as she had ordered.

Luna’s tail had already been wrapped into a bun like Celestia’s; succeeding in its role to completely expose her nethers for all to see and admire. She waited patiently for several minutes though while she was expecting Twilight’s arrival, the sound of the wooden door cracking open made her jump in surprise.

“W-Welcome, Twili--I mean, Mistress,” Luna corrected herself in time as she bowed her head to the lavender alicorn.

“You don’t need to be so formal yet, Luna,” Twilight approached the dark blue alicorn, making sure to not quite invade her personal space by remain close enough to make her presence felt. Like a predator measuring its prey, Twilight walked slowly and deliberately around Luna.

The slightly taller alicorn shuddered. She could feel the eyes of her smaller Mistress piercing her fur. She was evaluating her, inspecting her… grading her just like one would do to a slab of meat or a fashionable table-ware. Her eyes were everywhere and nowhere at the same time; her flanks, her slowly moistening pussy, her pucker, her teats, her barrel… all over her body.

“After all, we have a long road ahead of us. How long you ask? That answer depends on you entirely. Take my favorite slut for example,” at the calling of her title, Celestia also entered the room careful to close it behind her. “Remember I told you it took me two months to properly reign in Celestia? Well, partially. Most of that time was making sure these new laws would pass and become fully legal, as well as ensure the safety of all parties. Celestia herself? She was so eager to learn! It only took me two weeks to properly break her into a proper Pet. Ohhhhh, I had so much fun!” Twilight giggled like a filly.

“I… I see…,” Luna gulped. “S-So, how are going to start? The Contract didn’t say anything about a potential training period.”

“That’s because I planned around that. I founded an entire sub-section of Royal Guards dedicated to train Pets whenever an Owners asks for the services,” Twilight smiled stopping behind Luna. Using magic she spread her vaginal lips open, a single droplet of arousal ran down her folds and hanged on her clit before falling to the ground.

“S-So is one of those trainers going to educate me?” Luna asked trying to ignore Twilight’s actions.

“Nope! I’ll take care of that myself. You are my pet now, after all,” Twilight licked Luna’s slit slowly. She lapped at it a few times to properly taste her lunar slut.

Luna looked at Celestia, her sister beaming with pride. “I d-don’t deserve your graces, MistreeeessssSS!” Luna cried the moment Twilight began suckling on her winking clit.

“Tasty~” The lavender alicorn commented idly. “I see you’ve got some pointers! Good job, bitch!” She called praising the white alicorn.

“I live to serve you, my Mistress!” Celestia replied happily.

Luna was able to catch her breath, though part of her was itching for Twilight to continue. She was left hot and bothered, most likely as Twilight intended. Even so, she found her voice. “T-Then, Mistress, what are we to start with?”

“Nothing too complicated, everything considered. You see, almost everypony, or everycreature for that matter, have a misguided view on how to train slaves. And I do mean actual slaves here. I’m sure you remember those olden days when it was widespread?” Twilight hummed walking up to face Luna, who only nodded.

“Thankfully we have moved on from such barbaric times but misconceptions about that period linger still. So many ponies think that by being a slave you’d have to suffer from tortuous pain and indoctrination methods. You know, the whole ‘Carrot and Stick’ mentality?” Twilight scoffed. “While it is necessary in the process, I prefer to avoid it if at all possible. Do you know why is that?”

Luna thought about it long and hard. Training, re-education, and indoctrination were part of the process, as admitted by Twilight, so why not mention it in the contracts? What was the key difference between her, a Pet, and a slave? A few came to mind. Pets were protected by their own laws and while carrying the title of Slave, the entire point of a pony owning another pony via this entirely legal system was…Was!

Realization dawned on her. “Us Pets are willing slaves…”

“How sagacious of you, Luna,” Twilight praised. “Indeed. That is the main difference. You are willing fucktoys; pets, things, lowly objects to be treated as you so deeply desire,” Twilight chuckled making Luna flinch back in abject shock. “Did you really believe I wouldn’t notice? Your longing stares? Your quivering lips?” She leaned in to plant a long-drawn-out lick across Luna’s neck matting her fur in the process. “Your fucking scent? Spike and I had a bet on how much longer would you last before dragging yourself to me, begging to be a pet just like my kirin maker over there.”

“I--I--I-- Y-You… I…” Luna tried to speak, but every word found itself unable to pass her throat while her legs trembled.

“Tsk, tsk, tsk. No need to say anything, pet. I assure you I won’t cause you any pain… unless you get off on it,” Twilight shivered in clear lustful glee. “But I can see it, Luna. Deep, deep inside you,” she gave a chaste kiss to the quivering lips of the taller alicorn before continuing. “You’re jealous of Celestia, aren’t you?”

“...Y-Yes…” Luna breathed out, her legs giving in and falling to the ground. “Gods above, yes…”

“Understandable. I mean, how could you not be? Celestia is always so cheerful, so happy, so eager, and so absolutely bucking madly proud of being owned and used as little more than fucktoy! A damn cocksleeve has more worth than she does, and she knows it. But the best part? She’s no longer driving through the mist and steering the wheel. She is merely a luxury good on that boat I now direct,” Twilight giggled.

“Funny how that works, no? Arguably the most powerful being on the planet, excluding Discord, of course, desired nothing more than to be guided along a path instead of being the one guiding it,” Twilight smiled. “Don’t get me wrong, she did a wonderful job guiding the ship or else I wouldn’t be here today. But you, Luna? It must’ve been torture to see Celestia so complete, content, and fulfilled with her new role in life,” she said softly, as one would speak to a dog or a cat.

“Heavens, yes. Her beaming is so… so beautiful. When she walks… flaunting her pregnant belly… having no shame whatsoever exposing her body like that,” Luna swallowed. “Taking pride in obeying every order given to her… I envy her so, so much.”

“And not just her, riiiight~?” Twilight taunted.

“N-No… NO! Seeing so many mares and stallions around me serving happily! Always so cheerful, so gratified! And never giving a damn what others would say of them, doing everything they were told without a trace of shame!” Luna breathed out her anguish as the dam she had worked for countless centuries to erect in order to conceal her emotions finally broke down completely. “They were so… adored. Loved… And my dearest sister,” Luna looked at a teary-eyed Celestia. “I want to experience that same kind of love. For it, I will devote myself to my new place in life,” Luna confessed pouring her heart out. She didn’t even notice she had been crying for a while now, but that didn’t matter.

Twilight smiled picking up her chin. “Then our first lesson is a resounding success. Welcome, pet, to your new life.”

***********************************************

“Is this really necessary?” Luna asked with a blush crossing her face.

“Of course! It’s all part of the training,” Twilight replied calmly.

The two mares were walking around Canterlot’s main street. Ponies bowed and politely greeted their ruler as she passed flanked by her newest pet. They did a horrible job masking their glances. No. To fail one had to try, but they didn’t bother. Ponies and a few other creatures glanced at Luna as much as they desired. And how could they not? The dark blue alicorn was wearing a royal guard armor, or rather a fetishized version of it. Of course, it didn’t cover her exposed nethers, it made a wonderful job making her flanks look bigger, and of course, her small teats were being ever so slightly being weighted down by nippled hooks instead of piercings like her sister’s.

“I have a bunch of places to visit, and I will need my sexy guardbitch to protect me. It is only right and proper, after all,” Twilight teased.

“Of course, Mistress,” Luna bowed her head.

“Ah, look at that, we already made it to our first stop!” Twilight chanted happily as she entered the room.

Luna followed shortly after her Mistress only to find a shop that sold equipment and other miscellaneous items for animals.

“Ah, Princess Twilight Sparkle, my best costumer!” The owner of the shop called joyfully. “To what I owe the pleasure of your visit this fine day?”

“Hello, Suit Prose, I’m just looking for two bowl sets, some reward treats, a leash and collar; you know which ones, the sturdy kind!”

“On it, Princess. I presume it’s for your new pet over there?” The stallion said as he walked around the shop with precision grabbing the solicited items.

“Precisely. I got her two days ago and I am yearning to show teach her how to be a proper pet waiting at my beck and call,” Twilight pulled a small pile of bits from one of her saddlebags and placed them on the counter a moment or two before the stallion returned with her charge. “Thank you once again, Suit.”

“And thank you for your patronage, Princess! Have fun!” The stallion waved a hoof at the departing duo with Twilight simply teleporting away her newly bought equipment.

The duo continued their way; visiting shop after shop while Luna was subjected to the openly judging, thirsty, hungry eyes of the very same ponies that almost two years ago were her subjects. They cut through her swiftly and unashamedly, eating her up like she was a doll on display.

But that’s precisely what I am now, Luna told herself as she walked alongside Twilight.

Which was worse? That she didn’t mind that fact at all or that she silently welcomed their prying eyes?

She didn’t know.

***********************************************

Luna found herself again in Twilight’s personal dungeon. Unlike the previous days in which she enjoyed a fair bit of liberty and leniency, this time she was shackled to the ground while spreading bars kept her hind legs wide and open. A gag-ring was placed on her mouth alongside a magic suppressor and wing straps binding her torso. All of them the result of Twilight’s shopping spree. All for her.

Besides the dark blue alicorn, Twilight, Spike, and Celestia waited for the lavender alicorn’s instructions.

“We have a lot of work to do to turn Luna into a perfect pet. We have to work on her stamina, arousal response, fluid taste, obedience, pain tolerance, stretching, and gag-reflex,” Twilight hummed merrily with a scroll floating in front of her. “Celestia, be a good pet and help Luna with her pucker. She needs a good stretching to fit the plug.”

“Of course, Mistress. Your wish is my command,” Celestia replied.

Luna’s eyes widened. She knew Celestia was completely loyal to Twilight and no matter what she ordered she would obey… but to show not even the slightest hint of hesitation on her answer? Madness. It was madness.

“Graaahhlll!” Luna moaned, her tongue hanging out as she felt Celestia’s broad and large tongue lap her asshole once before plunging it. She could feel her sister’s tongue wriggle, coil, and twist inside her rectum with masterful and practiced ease.

“She’s quite good at it, isn’t she?” Twilight giggled stepping in front of Luna. Using a hoof she forced Luna to look up at her. “How does it feel to have your big sister’s tongue playing around inside your sphincter, pet?”

“...Ig...zheelz guuud,” Luna drooled out, her flanks trembling from the pleasure Celestia’s magic tongue provided.

“There’s nothing quite a good thorough cleaning after my bath~” Twilight sang. “Do you want to be just like her, whore?”

“JHEZZ!” Luna yelped loudly at the same time an orgasm struck her body. She gushed her marecum to the floor while Celestia, unfaced, continued her work.

“Then you have to learn to walk before you can fly, Luna,” Twilight kissed her snout. “First, we have to prepare your body properly for what’s to come. After that, we can move on to your behavior and temperament. It’s all part of the training process. What good is a pet that doesn’t obey and behave? It’s worthless,” Twilight said before encapturing Luna’s tongue between her lips and sucking on it for a good solid minute.

After Luna reached her second climax, Twilight released her tongue, uncaring about the amount of saliva the one-sided display of affection now staining Luna’s face.

“Spike, could you help me with Luna’s gag-reflex?” Twilight asked nonchalantly.

“You got it, Twi,” Spike flew over to Luna’s front with Twilight stepping aside.

Luna was no stranger to Spike’s member; she had seen it several times pumping seed inside Celestia over the course of the past months. But this was the first she had seen up-close. Her eyes went wide and tried to moan in protest, but the sudden intruder all the way to her throat prevented her from doing much else than gurgle out a groan of discomfort.

It only took a few thrusts from Spike and a third orgasm for her tongue to start lapping against the dragon’s crotch in between wet, gagging noises.

“Mistress, please! Let me cum! Let me cum!” Luna pleaded, crying as she desperately tried to release herself from her constraints to no avail. Unlike previous times, they were not in the dungeon but in Twilight’s room.

Behind her laid Celestia. Twilight had ordered her to tease, suck, and lick her blue cunt every now and then. She was charged with driving her to the verge of orgasm then suddenly stop and leave her light that until she was ready for another bout of teasing.

Meanwhile, she and Spike would work.

“Ah, ah, ah, Luna. You are my Pet. You don’t get to demand anything from me, your Mistress. What you get is what I believe you deserve, and for this misdemeanor, you just earned another twenty spanks. Let’s see… that would make it a grand total of one hundred and twenty so far!” Twilight told the bound Luna with a mischevious grin.

“I-I-It’s been hours, Mistress!” Luna panted through spit and heavy breathing. Her eyes burned with tears and reflected nothing but desperation and an urge to release. “I beg of you, Twilight, let me cum!” Luna cried again, begging for mercy. Celestia gasped in disbelief.

“You insolent wench!” Twilight spat angrily and walking up to Luna. “How DARE you use my name without permission, huh!?” Twilight used her magic to keep Luna’s mouth shut, making it impossible for the bound mare to say anything more. All she could do was cry more while moaning her frustration away. Nevertheless, Twilight smiled widely seeing the spark of fear in Luna’s eyes. “Get it through that thick skull of yours, Luna. I’m your Mistress. Your Owner. And you are…?”

Luna took several gasps of air as her nuzzle was suddenly released; spit and tears falling to the ground in equal fashion.

“A… A Pet,” she wheezed out her answer.

“Repeat it.”

“I’m… I’m a Pet.”

“Again.”

“I’m a Pet!”

“Make me believe it!”

“I’m your Slave, Mistress! Your willing Pet!”

Twilight spat on Luna’s face. Smiling widely, the lavender alicorn presented her nethers to Luna. “That’s right, bitch. I am your Owner and you are my Pet. I command, you obey. You will only speak if I give you permission. You will eat only when I say so. You will sleep where I tell you to and you will obey me as I see fit. Understood?” She ranted without glancing back at the helpless alicorn. “Now, service me as Celestia has done with you. Unless,” she glanced back enough to show a single eye to Luna. “You want to go back to your previous empty, sad life? You can do it. Just say you are done with this and---!” The ruler of Equestria cut herself short as a moan escaped her throat.

Luna latched her mouth against Twilight’s presenting backside. The dark blue alicorn sloppily began to lick, kiss, lap, and suck all over Twilight’s nethers. She even went as far as to make-out with the lavender alicorn’s puckered asshole for half a minute, much to Twilight’s delight, before she found her voice again.

“I’m a Pet, my Mistress.”

“Goooood bitch~”

************************************************

“Master, I think my sister is ready,” Celestia said after taking her tongue out from the inside of Luna’s rectum.

“Time to try out the buttplug, then,” Spike snorted a cloud of smoke in anticipation. He picked a rather large dildo, though not quite as big as the one snuggly residing inside Celestia’s asshole, and brought it close to the bound Luna. “Twilight is going to be so happy when she comes back from her meeting to find Luna finally able to take it!”

“I’m happy to serve my Mistress, Master,” Luna managed to say, her breath still agitated after half a dozen or so orgasms.

“Let’s try it out!” Spike rubbed his hands together before taking a firm hold of the buttplug’s base and presenting its tip to Luna’s tail-hole. “Easy does it,” he muttered as he began to push it inside.

“Mmmmfff!” She groaned but didn’t protest further than that. Speaking out would only earn her punishment, and she’d rather avoid it. Her Mistress could be so cruel and creative with her punishments. The last time she had misbehaved, Mistress had banned her from servicing her for a complete day!

Truly, while her Mistress was endlessly gracious, patient, and doting she was equally fierce and merciless. Not being able to fulfill her role as a Pet was the worst kind of torture imaginable.

“Gaahh!” Luna cried out as the dildo stretched the inner walls of her anus beyond its limits.

“You’re doing great, Lulu. Breathe then exhale just like I taught you. The first time is always the hardest. In time you will get used to it and even enjoy it!” Celestia reassured as she kissed her little sister’s cheeks.

Luna gritted her teeth, her expression showcasing but pain mixed with pleasure and undying determination. Stifling pained groan after pained groan, Luna could clearly felt being stretched to until levels and the dildo reaching depths she didn’t know she possessed. With a final push, the small knot popped inside Luna’s asshole; the fleshy ring wrapping itself around the base of the welcomed intruder and leaving out a small empty surface.

“There! Wow, Luna, it looks better than I thought it would!” Spike complimented.

“I’m so proud of you, little sister,” Celestia congratulated whilst nuzzling her beloved Luna.

“Hmmm,” Spike hummed before reaching for Luna’s slightly larger teats. He squeezed them a few times before smiling. “Twilight is going to be very, very happy! Your teats are ready for your first pair of piercings!”

Luna, once aghast at the sole idea of considering piercing any part of her body, let alone her sensible nipples, found herself oddly enticed by the notion.

If it makes Mistress happy, then that’s fine, Luna thought before passing out.

************************************************

“If somecreature demands something from you in the name of your Owner but your Owner is nowhere to be seen nor left prior commands, what do you do?” Twilight asked.

“I refuse to obey and search for my Owner,” Luna replied.

“Very good! Have another treat!” Twilight said with a warm smile before tossing a fresh piece of carrot at Luna. The taller alicorn caught it no problem. She smiled and hummed while munching her well-earned reward. “Now, for two treats, if your current Owner wishes to give you to another Owner for, let’s say, a friendly exchange, who will you obey?”

“My Owner is my Owner through the Contract,” Luna replied almost instantly.

“Whoooz a good bitch? Whoooz a smart girl?” Twilight said pursing her lips before throwing the two promised rewards.

Luna caught them easily once again. When she swallowed them, the doors of Twilight’s room opened up revealing a cum-stained exhausted-looking Celestia being led by Spike pulling at her leash. Luna remained still for a few moments as Spike gave Celestia permission to go to her hay bed.

“My, the guards were quite eager today, weren’t day?” Twilight pondered, amused. “They didn’t go overboard, right?”

“I was there the entire time, Twi. The guards were a bit rougher than usual, that’s all. I think the waitress outfit was a bit too effective,” Spike chuckled.

“I know! Pleeeease tell me it survived,” she asked looking at Spike worryingly. Spike shook his head. “Shoot. I really liked that one! I’ll have to ask Rarity to make me another one,” Twilight’s gaze lingered on Celestia’s tired form and smiled lovingly. “Gods, I love her so much. I think she deserves a little reward,” she turned to Luna. “Pet, clean my ever dutiful Royal Whore up with your tongue.”

“O-Of course... Mistress,” Luna replied with some nervousness. So far the only cum she had tasted belonged to her sister or her Owners. She knew this day would come sooner or later, and now that it stared down at her, Luna felt her throat clenching and dry. Already expecting a slimy, pungent taste.

Luna made her way to Celestia’s lying form in short notice. The moment she reached her, Luna proceeded to give Celestia’s flank a long, hard lap making sure to take in as much salty, lukewarm cum as it could take.

Remembering her lessons she didn’t swallow it immediately. Instead, she played around with it for a few moments and even though it wasn’t fresh, the sheer amount of it made it retain an almost jelly-like composition. Enough for her to chew it almost as if it was bubblegum. Then, she gulped it down.

Luna let out a satisfied sighed, licked her lips, and went down for another scoop. After finishing her second mouthful of foal-making jelly, she took notice that her sister’s pucker was slightly gaping and oozing cum. Knowing her next objective, Luna lowered herself to the ground until she was laying on the hey bed contrary to Celestia’s position.

With the easy access provided to her backside, Luna wrapped her lips around the older mare’s spread flesh and began to suck. Hard. Luna moaned in pure delight; her marehood leaking freely while she loudly slurped mouthful after mouthful of perfectly warm, virile, near nauseating stallion batter down her hungry gullet.

Only when not one more drop would come out did she stop only to continue her task alongside the rest of her beloved sister’s perfect body.

“It seems Luna deserves a reward, too, don’t you think so, Twi?”

“I think I have the perfect gift for such a smart and obedient slut~”

This is true bliss, Luna thought to herself, smiling as she did.

************************************************

“Saddle Arabia, Mistress?” Luna asked while Spike stood close by holding the hose that was currently being used to wash her up.

“Oh yes. Our diplomatic relationship with Saddle Arabia can very well be compared to that of the Crystal Empire. That’s why I plan on paying Sultan High Dune and Sultaness Shifting Sands a friendly visit tomorrow. That’s why I need you clean and presentable because you are going with me, pet.”

“As you wish, Mistress,” Luna replied with no hesitation. “But, if I may, why not bring Celestia? She is your favored pet, my Mistress.”

“I planned on bringing you both along, but Celestia is due any day now and I can’t risk the lives of my nephews and nieces like that. I also have a very important gift to give them as a sign of our friendship and alliance between nations.”

“I understand, Mistress,” Luna smiled as another gush of water hit her back.

“Speaking of gifts, how do you like yours, pet?” Twilight asked slyly.

“I love it, Mistress! Any gift of yours is a treasure,” Luna replied before lifting a hindleg allowing Twilight to see a sizeable golden ring attached to her clitoris.

Twilight nodded in approval. “Spike! Hurry up, okay? I need to prepare everything before I leave tomorrow!”

Luna lowered her leg and genuinely smiled. In only a month and a half, she had achieved her deepest desire and was now a true and proper Pet, just like her sister. She couldn’t be any happier!

************************************************

“It is always a pleasure to welcome our Equestrian brethren, Princess Sparkle,” Sultan High Dune said as he, his wife, the Sultaness, and a dozen guards escorted the lavender alicorn and her pet across the exquisite Sultan Palace’s hallways.

“The pleasure is all mine, Sultan. But, please, call me Twilight. Our nations are very close, we are practically family, so I think we can drop the formalities of royalty among friends?”

“If you are sure, then I shall comply… Twilight,” High Dune bowed her head gently in affirmation.

“As will I, of course,” added Shifting Sands.

Twilight smiled at them both in return. They spent the next few minutes in relative silence until they reached the throne room practically empty aside from the on-duty guards scattered around the room.

“Twilight, if I may be so bold?” Shifting Sands said cutting through the pleasant silence.

“Of course, Shifting Sands,” Twilight stopped and looked back at the Sultaness.

“We know of your most recent custom and practice. So I must ask, is your companion Princess Luna?”

“I must admit I wonder the same answer my wife seeks, Twilight,” High Dune added.

“Ex-Princess Luna is the correct term, I’m afraid. But yes, she is Luna. Present yourself, Luna.”

“A pleasure to see you again, Sultan, Sultaness. It has been far too long since I lost saw the beauty of Saddle Arabia,” Luna said softly and politely, uttering her first words since their arrival in the morning. “I am Luna, a Pet under the service and protection of my Mistress.”

“So the rumors were true,” High Dune breathed out. “Then am I to assume the rumors regarding the success and gradual acceptance of this new radical law are also true, Twilight?”

The alicorn nodded. “Indeed they are, Dune. Incidentally, aside from my visit, I wanted to discuss two short topics with you regarding those laws.”

“Those being?” High Dune asked raising an eyebrow.

“First, with your permission, I would like to extend a formal overreaching initiative so that Saddle Arabia may implement a similar or even carbon-copy law based on my system,” Twilight explained.

“That is a rather delicate matter to ask of us, Twilight,” Shifting Sands replied instantly. “What is your basis?”

“Saddle Arabia and Equestria are already intermixed, so culturally speaking it wouldn’t be that much of an issue. That aside, many Saddle Arabians have welcomed the system back in Equestria, I’m sure you know. With your official support implementing it would be a trivial thing,” Twilight sighed happily. “The Crystal Empire already implemented it and the results were the same as my own.”

“What results?” High Dune asked, intrigued yer wary.

“The government branches, all of them, as well as important officials, influential families or nobles using the system showcased a massive increment in efficiency and productivity output regarding their work. What little corruption there was died off and several thousands of confirmed impregnations have been confirmed leading to a minor population boom, plus increased stability,” Twilight explained her points expertly, but even so the two rulers of Saddle Arabia remained doubtful.

“The second topic is a bit more personal. It’s a gift from me, to you, regardless if you accept my proposal or not. Honestly, this is the real reason for my visit,” Twilight pulled two scrolls, Contracts, from her saddlebag. “All you have to do is sign the Contract my sweet darling pet has already signed, and I shall transfer Ownership from me, to you. Of course, the same rules and regulations still apply.”

The married couple remained in stunned silence for the better part of twenty seconds before replying.

“Why?” High Dune muttered.

“Because I wish for you to experience the benefits of owning an obedient, capable Pet firsthoof,” Twilight smiled at the two rulers.

“Luna… are you… are you okay with this madness?” Shifting Sands asked on shaky legs.

“What Mistress wants is what I want. She is so generous!” Luna proclaimed.

“I see you still need proof,” Twilight rubbed her chin for a few seconds. “Perhaps a small demonstration is in order. Pet.”

“Yes, Mistress?”

“You know what to do. Show then the goods~”

Luna bowed her head a moment later before turning around to face away from the small group of Saddle Arabians. She then bent down, both raising her ass high and pressing her face against the ground while she spread her legs wide enough to give a clear, full exposure of her marehood and buttplug. The position itself was quite familiar: the traditional position mares made when presenting themselves to be mounted.

“By Allah… is that a piercing?” High Dune asked pointing at the golding ring strapped to Luna’s exposed pearl. The Sultan audibly gulped while his painfully hard erection was in full display.

“It is, Dune,” Twilight used her magic to pull at the ring playfully a few times. “My precious pet earned it so that she may never forget what she begged me to become and what she so openly wished to achieve.”

“...Which is?” Shifting Sands asked, her own marehood clenching at empty air.

“A fucktoy. A Pet. A Slave,” Twilight replied with sickening gusto seeing the two rulers of Saddle Arabia and their entourage struggle to keep their obvious lust under wraps. “All you have to is sign the Contract, my friends.”

For a full minute, no creature moved. All were unable to move. Unable to think properly. Unable to react.

Until Sultaness Shifting Sands accepted the offered Contract... and signed it.

“Ain’t friendship simply magical?” Twilight asked in a sweet as honey tone.

Her goal fulfilled and a whole new life in front of her, Luna couldn’t agree more. Her only lingering question was if she would glow quite as brightly as Celestia once her belly started to grow with a new life inside it. Only time would provide the answer.

She honestly hoped that to be the case.

The end.
