Prologue: A Letter from Royalty

A Letter from Royalty

Dear Rarity,

I hope Ponyville is treating you well! My studies across Equestria with Spike have taken us far and wide, beyond White-Tail Woods, beyond the Smoky Mountains, and into the unexplored forestlands of the West. We’ve come across numerous isolated pony communities, each with its own unique culture that I wish to study in more detail and write about. It is the culture of our latest discovery that piques my interest the most, however, and gives me reason to write to you. Isolated from any other towns by a several hour hike, we discovered a large village, cut off from civilization by dense forest. They welcomed us in with open hooves - I’m unsure if word of my Princess status had ever reached them, or if they were just happy to have guests.

Either way, their culture quickly became a point of intrigue. From a young age, the colts and fillies of the village were put to work - though not in the conventional sense. Instead, they were put to work assisting their elders. The ways would vary from family to family - some trained their young to simply help around the home and the workplace, whilst some chose to encourage their young down more risque paths. The morals of such a thing of course concerned me, but I was also eager to try and understand their culture more. So, when they offered to help me train Spike into such a lifestyle, my curiosity for research got the better of me. Plus Spike was more than willing to try it as well, which helped me feel more confident of such matters.

For the previous few months this training has taken place, helping Spike to explore a life of dedicated assistance to me. Not just as a job, but as a lifestyle. He took to it well, though I must in confidence to you, I made note of certain shifts in his personality. Over time he became more submissive, and more eager to focus on my own wills and whims over his own. I was afraid he may be losing his individuality against his will - however, talking to both Spike and the villagers freed me of my worries. He was eager from day one of life to help me however possible, and my worries of loss of individuality are probably needless worrying - he’s just becoming more excited to help me as his training has continued.

We will likely remain with this community for another month or so before returning to Ponyville, during which time I will continue to study their culture. Their doctrine intrigues me, and I must say I think some elements of such culture can be brought into our own without disadvantage. I will certainly be writing a paper on what the locals have chosen to dub ‘Pet Culture’, though I may choose to refer to it with a perhaps less provocative name. Fortunately the relations ponies have with their offspring have always been somewhat liberal across central Equestria, but discussing a culture so contrarian to our own will likely be somewhat controversial.

I look forward to seeing you again within a month or two, as I am all of my friends, to whom I am each writing individually.

Yours,
Twilight Sparkle

I: An Unexpected Gift

One month after Twilight Sparkle's return to Ponyville.

Sweetie Belle had always been a bit of a mischievous filly. Perhaps not as much so as Scootaloo could be when she was determined to find the new “activity of the day”, whatever that may have been at that moment, but Sweetie was also not a goody-two-shoes, either. So when Rarity had announced that she was out to run a few errands, and that her sister was to absolutely not go poking around in her room because of a “very special project” that was being worked on, naturally the first thing Sweetie did when the coast was clear was scamper up to Rarity’s room. How could she resist such forbidden fruit?

The first thing she’d found upon tiptoeing carefully in was, she figured, the exact thing Rarity had said to stay away from. To give herself credit, she thought, Rarity had been awfully prissy and possessive lately...so taking a peek at this project surely wouldn’t hurt, as long as she didn’t touch or wreck it. She deserved that much, right?

The item in question was an unassuming brown box, which the young filly tilted her head at as she approached its resting place smack-dab in the middle of the floor. The box was taped shut at the top with some clear tape, but Sweetie figured that the convenient nearby scissors would take care of that if need be. The container was just barely smaller than her herself, but something caught her eye as she circled it slowly, pondering to herself. Scrawled elegantly on the side in marker was one simple arrangement of letters that she knew all too well, as it was (part of) her name: “Sweetie”. Okay, now she had to look. It had her name on it for crying out loud! Who wouldn’t look in a box that had their name on it, given the opportunity? Well, probably most ponies, she figured - but she wasn’t “most ponies”!

It took a bit of time and awkward fumbling, but eventually she managed to open the box and carefully extract its contents. A lot of it seemed to stick to itself, but with some good old elbow grease and a lot of shaking, the young filly managed to get all of the items laid out. Lying before her was an…”interesting” ensemble of clothing composed of a sleeveless leotard and matching socks (the rear ones with cuffs integrated), all made of latex, along with a small ring and a leash coming from what seemed to be a collar that was attached to the leotard. She was familiar with latex, to a degree she wouldn’t ever admit to, from past ‘accidental’ discoveries in her sister’s room. Sure, none of the things made of it ever fit...but it still had a scent alluring enough and a wonderful property of stretchiness and shininess that implanted itself into her mind. From the first time she ever got her hooves on it, she had enjoyed its company nonetheless. In fact...why couldn’t she just try it on? Rarity would never know so long as she put everything back...

And so she set to work with dressing herself, huffing and blushing gently as she tugged each sleek garment onto her body. She noted with a sort of odd mix of excitement and surprise that these rubber clothes actually fit her, accentuating every curve of her body flawlessly, and hugging her tightly and warmly like she’d never experienced before. It felt amazing, even if the collar/rear sock cuffs were a bit strange, just sort of being there. Come to think of it, where did the ring go? That didn’t seem to fit anywhere except around her horn...hm. Well, there it would stay for now.

“I didn’t know Rarity had this stuff…” she mumbled to herself, poking at the rather bizarre fashion choice of a leash coming from a collar that said “Pet” (whatever that was supposed to mean here). And as a matter of fact… “...why does it all fit me, though?”

And then she heard a voice that made her freeze exactly where she was in the midst of admiring her now thoroughly shiny hooves:

“Because that outfit was made for you, Sweetie.”

Horsefeathers...now she was gonna get it.

It was hard for Sweetie Belle to describe what befell her after her big sister caught her not only in her room against explicit instructions, but also wearing what was presumably meant to be a secret outfit only to be given to her later. All she knew was that Rarity simply wordlessly grabbed her in a swathe of blue magic and floated her over to the bed, pulling her upright onto her hind legs - despite her struggles and quiet complaining - as she fought the treatment. Despite this, she knew nothing she said or did would change Rarity’s mind...she only hoped that she could get lucky and escape somehow.

Her chance vanished very quickly, though. With a kind of mixture of surprise and dread, she observed a few more objects float into view from various corners of the room towards her. In just a few seconds’ time, she found her forehooves stretched above her and tied tightly together with a length of silky rope, which was then tied off to the top of the bed frame. She squeaked and tugged on the rope as hard as she could, before yelping slightly as she found a large, sleek pole attached to the cuffs around her rear hooves and locked in place. The magical hold was released at this point, but she quickly found that with her legs forced so wide apart, she wasn’t going anywhere.

“Rarity, I’m s-sorry, just l-mmph!” Her eyes widened as her apology was cut short by a huge ball gag forcing her jaw wide and being lodged snugly behind her teeth, and then strapped tightly and locked around her head. She shook her head furiously and tried desperately to speak or spit the gag out, only managing to produce a bit of drool from around the sizeable mass filling her mouth and pinning her tongue down. She was so preoccupied that she didn’t even notice the small bullet vibrator being carefully tucked into its rightful place below the leotard, and the remote being slid into the top of one of her hind legs’ socks...that is, until it was switched to ‘low’. Sweetie moaned slightly despite herself and squirmed in her bonds at the new unfamiliar sensations flowing throughout her body as Rarity climbed onto the bed, grinning sultrily as she grabbed the leash dangling from the latex leotard’s collar.

“Going through my things is very naughty, Sweetie Belle…” Rarity trilled, gently tugging on the collar to grab her little sister’s attention. As soon as they made eye contact, there was a loud thwack! noise. The filly let out something between a yelp and a moan as she desperately tried to escape her predicament, wincing as she saw the wooden paddle that Rarity now levitated in front of her teasingly.

Sweetie tried to plead with her eyes and some muffled attempts at speech to let her go, but the older unicorn was having none of it. The hungry smile on her face simply widened as she turned the switch on the steadily buzzing vibrator to “medium”, before immediately swatting the filly’s rear with the implement twice as she had the first time two times in quick succession, and tugging on the leash to force the eye contact even longer.

“...and naughty fillies must be punished!” Rarity finished, licking her lips as she saw in her younger sister’s eyes the feeling of complete helplessness amongst strange stimulation that was both painful and pleasurable. She was almost glad, in a way, that Sweetie had disobeyed her orders not to go snooping, because now it meant she could properly introduce the young filly to her role as a thing to be owned and toyed with. She’d been planning on doing so on her next birthday, with the outfit to be a wonderful present...but since she had already dressed the part, she figured that Sweetie may as well learn her place now so that she could have fun with her whenever she wished…

And even though the young filly continued to yelp and squirm constantly at each firm strike from the paddle, Rarity saw that each impact was driving her enjoyment of the insistently buzzing vibrator up...and she was blushing fairly heavily now. Sweetie would turn out to be a fine pet after all, she thought, smirking to herself. All that was left was to break her in, night after night. She would enjoy doing so greatly. As to whether Sweetie would enjoy it, Rarity figured she would as she became intimately familiar with both the pleasure and pain dealt to her. She giggled to herself as she gave one more particularly forceful blow onto the filly’s tight rump, eliciting the loudest moan she’d gotten yet…

This was going to be fun.

II: Pillow Thoughts

Sweetie laid in bed, her wide eyes staring out into the blackness of the duvet that shielded her. Tucked up safe and secure in the fetal position, her brain was on fire, thoughts engulfing her mind. What had happened that afternoon? Why had Rarity done the things she’d done? Was that even Rarity, brandishing such a cruel device? And what did that outfit mean? Sweetie had thought little of it when she pulled it on - she’d appreciated the wondrous craftsmanship, of course, such care and attention was to be expected of Rarity’s work after all - but it was just another outfit to Sweetie’s eye - no different to any other showy ensemble. Why had this one been the catalyst for Rarity to engage in such horrid behavior? And why had it felt as good as it had? She could remember Rarity mentioning the outfit being a surprise birthday gift for her, as well as it being a major part of another birthday surprise on the day itself... had she really ruined her birthday surprise that badly? And would it still be going ahead?

The look on Rarity’s face as she came in the door still made Sweetie Belle shiver. That look of pure, unadulterated disgust, and - perhaps worst of all - the way it had slowly morphed into one of quiet confidence and composure. The flustered filly rolled back and forth as images and sensations flashed through her head. Thoughts of the latex gripping her skin as she squirmed, tugging this way and that at the hairs in her coat. The dull wood of the paddle as it brushed across her flanks, the sharp stinging it left as it smacked against her. Perhaps most vivid of all, that cruel little vibrator that had been unceremoniously pushed into her leotard, pressed against her clitoris. Those teasing vibrations, those relentless vibrations.

Sure, Sweetie had played with herself once or twice - boisterous Scootaloo’s teasings at school had driven her to explore - but she was still hugely inexperienced sexually. So to go from minimal touch, straight to paddlings and vibrators had all been incredibly intense for her. She’d never made herself cum before - never quite confident enough to go that extra step and send herself overboard - but that afternoon she’d been pushed as close to the edge as she’d ever been.

But it hadn’t happened. Rarity had teased her and pleasured her, but deliberately cut the games short, denying Sweetie Belle the release her body wanted, even if her mind didn’t. But the filly’s thoughts kept gravitating back to that unblinking, stoic expression, almost sadistic in its composure as Rarity watched her little sister’s body quiver under her expert influence.

Tossing and turning back and forth, Sweetie eventually clamped her eyes shut, forcing herself to try and sleep. She had school in the morning, and waking up exhausted would do her no good. She had to sleep, regardless of how active her brain was.

* * * * *

BEEP
BEEP
BEEP
BEE-

Sweetie smacked her hoof down on the top of her alarm with a start. The shrill sound had long been one that Sweetie loathed - a piercing siren that was certain to destroy her chances of a peaceful morning. Rarity had always known that Sweetie didn’t like the alarm. That’s why she’d normally be in five minutes early, ready to turn it off herself and wake Sweetie with soft words and the aroma of breakfast, served in bed. The alarm was only set in case Rarity ever overslept. And Rarity never overslept - she was always busy. Perhaps she was just running a little behind schedule? Or perhaps she was taking an especially long time making a big breakfast, as apologies for her bizarre behavior the previous day.

After ten more minutes passed, however, Sweetie was becoming doubtful of that option. Finally sitting up again, she slid out of bed, groggily drawing her curtains open in her albeit weak magical grasp. As warm morning light flooded the room, Sweetie noticed the note that had been slipped under her door.

Quizzically she picked up the note, reading the carefully written message in Rarity’s over-elaborate penmanship. It simply said

Your Sister is tired. Make her breakfast. Toast and tea.

...oh.

Sweetie rummaged through the well-kept cupboards of the kitchen, finding the bread, plates, a filly-safe knife and a pot of posh Canterlot jelly from the fridge. She wasn’t one for cooking all that often, but she certainly wasn’t as terrible as perhaps she once was. With two plates of toast made, and a fully-brimmed cup of tea, Sweetie began to climb the stairs again to Rarity’s room, wincing a little as tea carelessly slopped from the cup onto the floor. That should wipe out.

Rarity’s room.

Pushing the door open with a free hoof, Sweetie looked to the bed where she expected to see her sister sleeping. Instead, Rarity was stood by the window, looking out onto the street, quiet at this time of morning before any stores had opened.

“H-heya Sis! I’m sorry that you’re so tired, though it’s a little strange - you’re normally raring to go of a morning… Anyway, here’s your tea and toast!”

With that, Sweetie carefully placed the tray she’d been carrying down on the bed, before lifting the tea-cup onto the bedside table. As Rarity turned from the window, striding towards the bed, Sweetie hopped up on top, lifting one of her pieces of toast to her mouth.

“Off the bed Sweetie.”

“What?”

“I said, off the bed. You’re going to get crumbs everywhere, and I don’t want a mess.”

Sweetie raised an eyebrow as Rarity maneuvered herself back under her sheets, lifting her plate onto her lap - all the while glancing Sweetie Belle a judgmental look.

“But, you’re sitting in bed anyway! You’re going to get crumbs everywhere too!”

Rarity’s lip twitched at her sister’s standoffish attitude.

“You’ve been told once. Get off my bed. You’re perfectly entitled to sit in here with your sister, but you need to sit on the floor.”

“Sweet Celestia you can be stubborn…” Sweetie scoffed to herself under her breath, sliding down off the edge of the bed, sitting at its end. The two sat eating their toast, the only sounds between them being the crunching of eating, and the singsong of birds outside the open window.

As the last of the toast vanished, Sweetie dropped her plate down on the tray, taking a moment to collect herself. Glancing up at the clock, she noticed the time.

“Oh horse apples, I’m going to be late for school! Rarity I need to go!”

She leapt up, bolting towards the door, before suddenly feeling herself come to an abrupt stop. Rarity’s magic held her in place, the tray and dirty plates floating forward into her vision.

“Wash these up. If you do it sharpish and jog, you can still get to school on time.”

Rolling her eyes, Sweetie took the stacked tray in her grip, walking briskly down the stairs to the kitchen. Pausing in front of the sink, she glanced at the clock again. She didn’t have time. Dumping the plates in the sink, she grabbed her saddlebag from the lounge, bolting for the door.

Rarity listened from her room as the front door slammed shut. She already knew Sweetie hadn’t done the dishes. Typical ungrateful foals. Rarity had a lot of work to do.

IV: Training Day

The last light of the evening sun poured in through Sweetie’s open window, illuminating her innocent face and the table at which she sat. Floating in the green warmth of her magic was a crayon, which she used to color a picture of Princess Celestia she’d drawn. It was by no means fantastic, but Sweetie was still pleased with it. Drawing was a big hobby of hers, one that she hoped to take further someday. Her attention was torn away from the page, however, by her Sister’s voice emanating from behind her.

“Come along Sweetie. Let’s watch television together.”

“But Rari! I’m coloring!”

Rarity took a step forward.

“Come and watch television with your Sister. She’s asked you once.”

Either Sweetie didn’t catch the severity of her tone, or she willfully ignored it. Either way, Rarity watched the filly not getting out of her chair. Shaking her head to herself, she strode up to Sweetie’s side, lifting her hoof to her chin, before slowly yet forcefully pulling the filly round to face her. She craned her head down, leaning in, looking the filly straight in the eyes.

“Go downstairs, before I make you.”

“Nuh-uh Rarity! I don’t wanna.”

Rarity pulled back, her face neutral.

“Very well.”

And with that, she spun on her heels and left the room, leaving the door open.

“Heh,” Sweetie thought to herself, turning back to her picture, “score one for Sweetie Belle!”

The filly practically leapt out of her skin with shock as she felt a large, leather collar constrict around her neck. She gasped, pawing at the desk, the grip cutting off some of her air.

“Too tight for you? Apologize for that attitude and I’ll loosen it.”

“S-SSohrry Rarrityyi-”

“Close enough.”

With that, Rarity loosened the collar, allowing the leather strip to slide through the metal clasp, pinning it in place at the acceptable tightness. Listening to the little mare gasp and gag as she caught her breath, Rarity took ahold of the leash that had been attached to the collar, pulling at Sweetie’s neck. The little filly wasn’t going to win this. Giving in, she clambered down from her chair, following a few steps behind her Sister, down into the lounge. There, Rarity took her place on the couch in front of the TV, patting the space beside her. Dejected, Sweetie did as she was told, sitting on her flanks beside Rarity.

The TV clicked into life. Some Canterlot fashion show she’d never heard of, featuring a stallion and a mare she didn’t recognize, discussing a style of clothing she didn’t understand. It wasn’t long until she’d zoned out, sinking into herself, focusing most of her attention on ignoring the terrifying mare sat beside her.

This didn’t make sense. Apple Bloom and Scootaloo didn’t know what they were talking about. There was no way this was a normal ‘coming of age’ thing. It couldn’t be… Could it? There was a lot about the world she didn’t understand, so maybe this was normal? Maybe this was just a phase all adults went through with their siblings… it couldn’t go on forever. But perhaps this wasn’t so bad? They were just watching television...

Sweetie quickly stiffened up as her body started to tingle. Every inch of her skin started to warm, as if she’d submerged herself in a slowly heating bath. As her vision of the world tinted blue, Rarity’s bubble of magic that engulfed her had fully formed. In one smooth motion she’d been lifted upwards, turned at an angle, and placed down over Rarity’s lap. Sweetie turned her head to question her sister, but nothing happened. The magic held her still.

Suddenly, the magic began to pull at her jaw. Confused, and unwilling to put up a fight for fear of hurting herself, Sweetie allowed her jaw to loll open. Very soon, though, she was desperately trying to lock it shut again. The ballgag was back.

Unable to combat Rarity’s magic, the little filly could only sit there as the gag came to rest behind her teeth again, the familiar click of the lock shutting behind her head. But just as she had accepted the foreign object into her body, another one was teasing at her. But with Rarity’s magic holding her still, she couldn’t see it. She could only feel it.

The tip of the dildo rubbed cruelly against her asshole, the excessive lubricant dripping down from the shaft, running down the folds of her vagina, forming a sticky pool on the couch. Without saying a word, Rarity began to push the dildo against her little sister’s hole. The filly shook and squirmed with discomfort as the silicone cock teased her ass. Something had to give out eventually, however, and Rarity’s magic wasn’t going to stop any time soon.

Sweetie’s asshole parted in a satisfying manner, slowly consuming the tip of the dildo. Rarity smiled as her little sister yelped in shock - though the poor creature was still shaking like a leaf in a gale.

“Sshh, sshh, thaaat’s it little one. Don’t tense up, just take deep breaths. Relax for your sister, and this will only get easier.”

As one hoof rested over Sweetie’s back, the other lifted up to her head, slowly and lovingly brushing at her mane, like a doting mother reassuring a foal after grazing their shin. Sweetie’s mewls eventually trailed off, her body acclimatizing to the uncomfortable stretching of her rear end, as well as the slow, deliberate pattern of thrusts. The dildo pushed deep into her rectum, dragging along its warm walls, but never going so fast or so hard as to be unbearable.

Confident Sweetie had eased into it, she returned her focus to the television, watching two of her favourite Canterlot designers, Fine Stride and Dainty Boots, discussing their latest fashion creations. It was her dream to work with them some day. They were two of her many idols - and of course, the Canterlot street cred and cash wouldn’t go amiss.

Perhaps deliberate, perhaps distracted by her show, Sweetie could feel the dildo’s pace increasing. With each thrust it pushed that little bit deeper and that little bit harder, the exaggerated base stretching her out that little bit further. The mewls and whines that had once escaped her lips had slowly started to morph into moans and groans, the filling of her rear and the gentle stroking of her mane appealing to the most sinful of her senses. Her whole body had started to grow warmer and warmer as the sensations grew inside her, much of her body tensing and tingling in strange ways - sensations that were fresh in her memory after the events of that earlier night.

Feeling the little filly shake, and listening to the muffled sounds that were clearly trying to form words, Rarity granted Sweetie a little luxury, removing the gag from her mouth.

“Rarity, m-my filly parts feel funny, I-I thi- something’s happenin-g!”

The dildo lurched to a sudden stop. The hoof that had gently brushed her mane lifted away, taking ahold of her chin in that all familiar way, turning her head. This was what Rarity had been waiting for.

“Sweetie Belle, that’s called an orgasm. You need to orgasm. You need to cum. An orgasm is the best feeling a filly like you will ever experience in their life. Once you’ve felt it, you’ll understand. But little fillies aren't supposed to make themselves cum - it's very taboo. Only an adult like me can make you cum. Only your Sister. Do you want that? Do you want to cum, Sweetie? Your Sister can make you feel very good.”

The unicorn smiled to herself as her little sister urgently nodded. Exactly the response she needed.

“Excellent. In that case Sweetie, climb down off the couch, and lie down on the floor. On your back. Mind that dildo.”

She watched as Sweetie did so, before climbing off the couch herself, coming to rest by her sister’s side.

“Now Sweetie, spread your legs for me. I need to see your pussy.”

As the filly did so, Rarity reached her hoof forwards, resting it on her quivering folds. She listened as Sweetie inhaled sharply, the magnitude of her sensations clearly massive. Focusing her attention on Sweetie’s cute little clitoris, she began to rub her hoof back and forth, picking up speed as she went. As if subconsciously trying to match her, as Rarity grew faster, Sweetie grew louder, her breathy moans transforming to a constant high pitched whine.

“Do you want to cum, Sweetie Belle?”

“Y-Yes Rarity, I do!”

"And who's the only one that's allowed to do it?"

"Y-You are Rarity!"

"When are little filles like you allowed to cum?"

"Only when their Sisters allow it!"

“Tell your Sister exactly what you want Rarity to do.”

“I want Rarity to make me cum!”

“That’s it.”

And with that, Rarity rammed the dildo as deep into Sweetie’s asshole as it would go, pulling her other hoof away from Sweetie's clit in the same motion. Sweetie’s head jerked back as the sensations trapped inside her exploded free, cum catapulting itself from her pussy. As one jet followed another, Rarity leaned back to avoid the mess, watching it splatter across the floorboards. She was quite amazed to see just how long the orgasm lasted, Sweetie’s body jerking and twitching as more and more cum shot free. Eventually the spray subsided, leaving only the occasional slow drip running down the inside of her thighs as Rarity slid the dildo free.

“Good mare. Now, you need to go to bed. You have school in the morning - why don’t you take a shower tomorrow for a change? And hey, you’re a pretty young mare, you know that? That collar suits you, really brings focus to your face. You should wear it to school. I think that would be cute.”

Sweetie Belle - far too exhausted to argue for now - wobbled to her hooves, slowly and uneasily making her way up the stairs, back to her room. On more than one occasion her legs gave out from under her, leaving her in a heap on the floor. Each time she lurched back up, a little of the cum that soaked her thighs was flicked loose, splattering on the floor.

As she flopped down onto her bed, two tired hooves lifted up to the collar, fumbling with the catch. Like she was gonna wear it to school. But try as she might, she couldn’t get the catch loose. Giving in, she let her head flop back against the pillow, falling asleep instantly. She’d take it off in the morning.

Little did she know it was locked in place. Rarity was a master in the way of manipulative magic.

VI: Going In Hard

Two Weeks Later

Rarity sat in the lounge, reclined across one of the couches. A pretty little notebook floated above her head, Rarity’s neat handwriting scrawled across the gold-leafed pages. As she added to the latest empty page, she thought to herself about her little project. Sweetie had been making progress, though it had at times felt painfully slow. On the one hand, she had started to engage more with Rarity during their training sessions, but on the other, she still harbored that frustrating defiance a confident foal had. Of course, said defiance was always met with punishment, but Rarity was starting to wonder if harsh words weren’t quite having enough of a lasting impact.

Mulling over her last note, she snapped the book shut, before sliding off the couch and onto her hooves. Sauntering through to the main room of the boutique, she picked up her latest creation - a frilly garter belt, made to measure for the little one. Perhaps a little modelling would be fun!

Trotting up the stairs, she arrived at Sweetie’s door, pushing it open. Then her magic dissipated, the garter belt dropping unceremoniously to the floor.

Sweetie Belle was sat on her bed, straddling one of her pillows. With her legs spread, each jerking movement dragged her exposed pussy back and forth, leaving a slick mess of fluids soaking into the pillow and the bed itself. Her face was an exhausted mess, a deep red, an expression of need, confusion and desperation plastered across her face.

“Oh Sweet Celestia Rarity why can’t I cum I need to cum please please please it’s been so long and it felt so good I-”

Blocking out the filly’s ramblings, Rarity lunged forwards, grabbing her by the now ever-present collar, jerking her off the pillow and down onto the floor.

“HOW DARE YOU! I told you that only your Sister can make you cum! Little fillies like you aren’t supposed to be doing things like this on your own!”

Sweetie’s voice was a stuttering mess, a mix of shame and tears as her emotions swamped her.

“I-I-I’m so sorry Rarity it’s just been two weeks since the last one and you made me feel so good and I really needed it again why couldn’t I make it happen…?”

Rarity hauled Sweetie up onto her hooves, forcefully guiding her through the house by her collar again.

“Because, Sweetie Belle, I had a suspicion that a defiant little mare like you couldn’t be trusted, that you would flagrantly defy your Sister’s sagely instructions and try to masturbate on your own. So that big collar of yours? Infused with a little of Rarity’s magic. You see, not only is it locked in place, it also stops you being a slut. The only way you can orgasm is if I personally, verbally allow it.”

Descending the staircase, the two entered the main tailoring room - coming to a stop in front of an additional set of stairs.

“Down you go. First door.”

The basement? But there was nothing down there - just an old storage room and a walk-in wardrobe. Thoroughly put in her place, however, Sweetie could do nothing but bow her head and descend, slowly pushing open the first of the two doors.

The store room wasn’t a store room.

Well, it may have stored something, but it certainly wasn’t just fabric anymore.

The small, organised storeroom was now a hectic, cramped mess. Two of the walls featured huge shelving units, as they had before, but now the shelves were stocked with all sorts of perverse toys and materials. The exposed wall at the back - once a space for notes and lists to be pinned - was now lined with a terrifying array of tools, many of which Sweetie couldn’t even start to understand. She recognized one, though, the hefty paddle that Rarity had used on her that first night. The filly stopped stock still in the middle of the room, her ears pricking as Rarity sauntered in behind her, pulling the heavy door closed - locking it shut.

“I didn’t want it to have to come to this, Sweetie. I really didn’t. I wanted us to reach an agreement like civilized ponies. But you leave me no choice. It’s time for your Mistress to fully take charge.”

“...M-Mistress?”

Sweetie sounded so small, so lost, like a filly that had woken up alone in the middle of the Everfree.

“That’s right. Big Sisters always know best, but a rebellious little filly like you clearly needs to be reminded of the hierarchy - that way you might actually come to accept the way things are meant to be between siblings now. You know, that orgasm denial spell was only going to be temporary. Three weeks at maximum, and once I knew you had self control I’d have cancelled it, given you the choice of when to orgasm. But you’ve proved to me that’s not an option now, that you’re not to be trusted. So I guess my only choice is to leave that spell active. Forever.”

She strode past the filly, rummaging through one of the shelves for a moment.

“Now, you’ve worn latex before. It’s a wonderful material, and it makes you look very, very pretty. You’ll be wearing it a lot from now on. Every day, in fact. But I don’t think you quite acclimatized yourself with it. Smell this.”

Held aloft in her warm magic glow, the piece of latex flew through the air, plastering itself over Sweetie’s muzzle, cutting off her air. Instinctively she tried to back away, only to hear a tut from her Sister - the filly couldn’t back away for long though, and very soon she found herself pinned against the near wall. Nowhere to go.

“How does it smell?”

Five seconds passed. The smell of rubber filled her nose.

“Take it all in.”

Another ten seconds.

“Learn to love it.”

Twenty seconds. The filly gagged.

“How does it feel against your skin? You’d best get used to it now.”

Another eight seconds. Finally, the chilling unicorn pulled it away, watching Sweetie drop down onto all fours, choking for air.

As she laid still, gasping, Rarity quickly floated more gear her way, this time adeptly forcing a latex knee-high sock over each of her hooves, each with a strange metal ring on the sides. The latex was stiffer than normal, leaving her knees difficult to bend. With her mouth open, a ring gag easily floated its way into place, the strap tightening behind her head - and finally, perhaps most humiliating of all, a saddle. Saddles weren’t a common sight in Equestria - she’d only ever really seen Big Macintosh wearing one whilst giving little fillies ‘Pony Rides’ at those Sweet Apple Acres Fun days.

“Look up.”

Begrudgingly, Sweetie lifted her head - her eyes settling on a small piece of apparatus in the middle of the room. The base of a rocking chair - more specifically just the runners that rested against the floor, with four hoof sized spaces in them. At one end rested an imposing dildo on the end of a pole, and at the other, a chair.

“Get in, Pet.”

Pet?

Slowly lifting herself to her hooves, Sweetie moved forwards, keeping her eyes towards the ground. She positioned herself over the piece of equipment, placing each of her hooves into the gaps. As she did, Rarity slipped a padlock through each of the rings on her socks, attaching them to identical rings on the framework itself. Running her hoof along Sweetie’s back, she felt the filly shiver as the tip of the dildo was pressed against her asshole. It was much larger than the previous one - and where the previous one had been a simple tapered cylinder, this one was frighteningly realistic - the flared head grinding against her hole, teasing, slowly stretching it further and further.

“Do you like it, Pet? It’s actually modeled on a real stallion. Big Macintosh. He and Applejack were more than willing to let me take measurements and make a replica, especially when they heard what use it would be put towards. I think Twilight’s ideas might be starting to really catch on in ponies’ heads. But you needn’t be concerned with things like that. You’ve got more important things in your life to concentrate on. Things like…”

Rarity trailed off as she pushed the dildo further, the flared tip finally overpowering Sweetie’s defenses, the head vanishing into Sweetie’s rear. Sweetie gasped in shock, but that was her problem. She would have to get used to this.

Finished round the back, Rarity took her place in the seat in front of Sweetie’s face. Slowly spreading her legs, her crotch was directly in front of Sweetie’s eye-line, leaving her staring at her exposed pussy.

“You love this view, don’t you Pet? Well, don’t worry. It won’t be changed forever.”

...wait…

What?

That familiar warm blue glow again, this time descending on Rarity’s crotch. It was a little difficult to make out through the bright blue light, but it looked like… something was coming out of her pussy?

With dawning horror, Sweetie watched as slowly, inch by inch, a penis began to develop from within her. As it elongated, it also expanded, widening and widening until it was easily the thickness of a well-hung stallion. More and more flesh added to the powerful tool, pushing the expanding tip forwards, until eventually it pressed against Sweetie’s muzzle.

Rarity, her teeth gritted, lightly poked her still-forming cock with her hoof, jabbing the flared head downwards. The rod flicked off of Sweetie’s muzzle, now coming to rest perfectly against the ring gag.

“aaaaAAAaah, get ready Pet, your Mistress is still growing, and there’s only one place for it to go…”

As the flared tip pushed against the ring, Rarity quickly found herself growing impatient, the hunk of flesh unable to naturally push itself through the small ring. So she wrapped her hooves around the back of Sweetie’s head, pushing her forwards, until eventually Rarity’s own tip jolted forwards into Sweetie’s mouth. A few more seconds passed by, and finally the blue glow dissipated. Rarity’s vagina had now been replaced by an impressive cock and a pair of hefty testicles, resting atop the seat. With her hooves still gripped around the back of Sweetie’s head, she started to slowly pull the filly forwards, tilting her whole body on the two rockers. As she tilted forwards, more and more of Rarity’s cock slid down into her, bulging out her throat like a snake that had swallowed a sheep. With each inch towards Rarity, a little more of the fixed dildo in her asshole slid free, exposed again to the cool air of the basement. Rarity slowed the push, watching her little sister’s eyes beginning to water profusely. She’d only taken about half her cock down her throat, but she’d learn to do better.

After an uncomfortable length of time, Rarity let go of Sweetie’s head, allowing natural momentum to rock Sweetie backwards to a neutral position - of course allowing the dildo in her asshole to slide deep inside again. Forwards Rarity’s hoof went again, this time pressing against Sweetie’s shoulder, pushing her backwards, further and further onto the dildo. Her asshole had had its fair share of training in the last fortnight, with daily evening sessions and the introduction of a butt-plug to be worn to school in the last few days. As a result, the dildo managed to slide in with ease, only slowing as the medial ring met Sweetie’s hole, though it too was quickly pushed inside.

Again, Rarity pulled her hoof back, allowing Sweetie to return to her resting position. This time she rested her hoof on the filly’s head, brushing her mane again, in what Sweetie had come to realize was an almost sick display of power.

“Now, little Pet. You understand how to play Mistress’ game now, so now you try. And don’t think you can just take it easy. You know I’m watching.”

Unsure which of her holes to punish first, Sweetie sat still for a second. Instinctively she settled on leaning backwards, testing her asshole - it was the hole more acclimated to cock, after all, so it just felt easier.

“Thaaat’s it… you’re getting the hang of this,” Rarity purred as her Sister slowly rocked back and forth. “There is no point trying to be defiant, little one. You know who is in charge, deep down. The sooner and more willingly you embrace it, the easier I can be on you. Difficulty is only going to be met with discomfort, so don’t make it difficult. It’s as simple as that.”

Back and forth the filly rocked, the respite of one of her holes loosening being combated by the other uncomfortably stretching out. The two sat, almost in silence as Sweetie forced herself back and forth, the occasional grunt and moan the only vocal sound to escape either of them.

Suddenly, Sweetie could sense her Sister tensing up. Her whole body had gone stiff, her hooves slamming down on her thighs. As she tensed, she suddenly stood, kicking the chair backwards, sending it clattering to the floor. On her hind legs, she reared backwards, trying to dislodge her cock from Sweetie’s mouth. Out slid her cock from Sweetie’s throat, stopping abruptly in the mouth. The flared head had caught on the ring gag. Unable to free herself without a slow and careful effort, Rarity hastily fumbled with the locking strap behind Sweetie’s head. Freeing the lock, the ring gag came away, firmly stuck over Rarity’s shaft, squeezing against her, crushing her urethra.

“Oh, Sweet Celestia…” Rarity muttered to herself, a slight panic in her voice, despite her attempts to hush her tones.

From the alarming pulsating of her cock and balls, it was clear to Sweetie that Rarity was ready to cum - or trying to - but that ring gag was squeezing her urethra, stopping the flow of spunk. With a frustrated roar of effort, Rarity’s magic consumed the ring, before suddenly snapping it in half.

In that split second, Sweetie realized just how scary that was. In times of heated emotions, Rarity’s magic had the strength to break metal. What would it be able to do to her if Rarity got angry?

She didn’t have time to think about that.

With the ring gone, Rarity let out a primal scream, both her hooves frantically jerking back and forth along her shaft. As they did an explosion of semen surged forwards, the first spray so powerful it physically stung Sweetie’s cheek. The thick white liquid coated her muzzle, causing Sweetie to have to clamp her eyes shut. The second load followed almost immediately after, soaking into her mane and eyelashes. Then came the third, straight across her muzzle again, several droplets firing up her nostrils. The forth crashed into her chin, sending great wads of the spray in all directions, splattering the floor. And finally, the fifth, smaller load drained itself onto the floor, cascading down from Rarity’s tip. Her legs shook violently as her knees bowed inwards, the power of the orgasm taking its toll. Clearly the first orgasm of a magically developed cock had a far greater impact than one would expect.

Rarity stood, bent over, trying to catch her breath again as the intense feeling subsided in her loins. Wobbling backwards, she righted her chair, flopping down onto it. Once her composure had returned, she stopped to look at the mess she’d made.

“My word, Sweetie Belle,” she exclaimed between breaths, “I don’t think I’ve ever seen you looking so gorgeous, your face painted with the seed of your Sister. It just looks so right - that pretty cum-stained body of yours is beautiful. I-”

A sound emanated from upstairs.

From the reception, the ring of the phone. Immediately her business professional self, Rarity was on her hooves, climbing the stairs. Sweetie could only listen, her head hanging down as the seed slowly congealed over her face, a painfully small amount dripping away onto the floor.

“Hello? Oh, hello!”

Pause.

“Yes, I’m very well, thank you!”

Pause.

“Haha, don’t you worry, she is absolutely splendid too! We’ve just been playing together before dinner!”

Pause. A longer one this time.

“Oh? You wish to speak to her? Very well. One moment.”

The clattering of hooves on floorboards. The echo of a pony descending stairs. The door opened again. There was Rarity, the wireless receiver held in her magic.

“Sweetie darling? It’s Mother!”

Rarity floated the receiver towards Sweetie, hovering it beside her cum-stained ear, an especially large bead dripping from it.

“...H-Hi Mom…”

“Hello Darling! How wonderful to hear you again! It’s been a little while! I hear you and Rarity have been playing games together!”

“....”

“...yes, we have Mom. It’s been fun.”

“Excellent! You two are such wonderful mares. I’m so proud of both of you! Oh, I’m sorry sweetheart, your father is calling, I think he needs my help with something! I’ll talk to you soon. Bye Darling!”

And with that, the receiver clicked. Sweetie looked up at her Sister, who had been stood over her the entire time. Her hooves had been crossed, and her eyes were filled with fire - a fire that had thankfully now started to fade.

“Good Pet. I’m glad you know the appropriate way to talk to your Mother - there would have been some really big problems for you if you’d said something you shouldn’t have. Now, let’s get you out of that rocker. It’s time for dinner. I think we’ll just have fish tonight. Tell you what, cook it well, and I’ll let you shower all that cum off this evening, before you go to bed. How does that sound?”

Ruffling Sweetie’s hair, she released the four locks and pulled off all the gear the filly was wearing, before dislodging the dildo from her asshole and patting her on the flank, sending her up to the kitchen. The unicorn smiled to herself as the little filly climbed the stairs. Training was starting to ramp up now, but surely her labors would bear fruit soon. It was in that moment her mind slipped back to a conversation she’d had a week or two before. A conversation with Rainbow Dash: a conversation about how excited Scootaloo had been to find out about Sweetie Belle’s ‘games’. Perhaps a playdate was in order.

VII: Catching Up With Friends

“Darlings! Hello! Come in, come in, please, make yourselves at home!”

Sweetie’s ears pricked up. Rarity’s voice was coming from the front door, which could only mean someone was visiting! And if someone was visiting, Sweetie wanted to see them! She carefully folded up the piece of fabric she was holding, putting it back onto the shelf Rarity had instructed her to sort and file. She began to canter towards the door, stopping herself short. She’d been told to stay in the basement and work until Rarity told her otherwise… if she just gallivanted her way into the lounge without permission, she would no doubt be shouted at, or worse. Her head and tail drooping, she turned back towards her work.

“Darling! Come up here! Some friends are visiting us!”

Sweetie’s eyes lit up. Throwing the door open, she bounded up the stairs, skittering down the hallway, coming to a stop in the doorway of the lounge. Rainbow and Scootaloo! Sweetie bounced forwards, giving her friend a crushing hug. The two stayed close for a moment, until both pulling away, slowly taking in what the other was actually wearing.

Sweetie was wearing an ‘outfit’ that mainly consisted of collars and belts, surrounding her neck and hooves in leather and latex - whereas Scootaloo was far more dressed up. She was wearing a frilly dress, black and white, with a small pinny around her midriff and a dainty looking piece of headgear. The whole thing was unashamedly girly, something that a tomboy like Scootaloo would surely normally loathe to be seen in…

Sweetie cocked her head, opening her mouth to speak, before Rarity interrupted.

“Isn’t she adorable, Pet? One of my own designs, you know - commissioned by Rainbow Dash, of course…”

Rainbow smiled, following Rarity as she motioned for the four to move over to one of the couches. As Rainbow started, she gently patted Scootaloo on the head as the filly eagerly stepped into line.

“You did a fantastic job of it Rarity! I love it, and so do all the rest of the Wonderbolts! They simply cannot stop checking out this beautiful little mare whilst she’s doing her work! Isn’t that right Scoots?”

“That’s right Master! It doesn’t matter what I’m doing, there’s always somepony watching me, giving me encouragement, complimenting my body! It’s so sweet of them all! I love them all so much!”

The color drained from Sweetie’s face. It wasn’t just her.

As the two adults sat on the couch, Sweetie just stared forwards at her friend, who had obediently laid down on the floor at Rainbow’s hooves. Sweetie flinched as Rarity patted her rump, shivering as her sister leaned down, whispering in her ear to go and play with her friend.

Rainbow and Rarity chatted idly as they watched the two fillies start to play together, with Scootaloo taking charge, eagerly rubbing her hooves along Sweetie’s flanks, towards her nether regions.

“Aren’t they just the cutest little things?” Rarity cooed.

“Ha, you know it Rari! Man, I tell you, I just can’t believe how quick they’ve taken to it! How long ago did Twilight get back from her travels now? It’s gotta be just under two months, give or take, right? And yet the little fillies have taken to their training like ducks to water!”

Rarity smiled, watching Scootaloo’s tongue pop in and out of her mouth, dancing across Sweetie’s well-used ass. She didn’t want to admit that Sweetie hadn’t fully taken to it yet - she didn’t want to be outdone.

“I know… Twilight comes up with some incredible ideas, doesn’t she?” Rarity asked, dodging Rainbow’s statement. “I mean, after she wrote her paper on ‘Pet Culture’ and started publishing it, a lot of the folks around Ponyville have really taken to the idea! I’ve actually started having ponies on the street come up to me asking for clothing commissions for their own pet projects! How amazing is that?”

“Wow! How many?”

“At least five or six individuals, including your good self. But I know there are a fair few more around town that are getting into it too, they just aren’t the sorts to be wanting my kind of fashion. Speaking of, that reminds me, how is Applejack’s little ‘Farm Relief’ Project coming along, as she calls it?”

Sweetie’s head sunk towards the floor again. Not Apple Bloom too…

"Oh man, you should see that little filly go now! She took to that like a pig in shit! AJ taught her to ask Big Mac if his cock needed cleaning every single day, even after every long day of work, and what do I see when I visit? The little angel is licking sweat from his whole body!"

“Oh, ha ha! He’s a big stallion, must take a little tongue like that a very long time!”

Rarity’s playful laugh sent shivers down Sweetie’s spine as Scootaloo motioned for her to lie down on her back. Hit by a wave of surrender, Sweetie laid down, spreading her legs to expose her pussy to the little orange filly. Her mind started to drift away from the adults, Rainbow’s words fading out as she talked about Applejack and some kind of ‘ long term breeding plan’, whatever that was.

“Hey Sweetie, what’s got you looking so glum for? Hey, I know what will cheer you up, let me show you a little trick Rainbow’s been having me practice on her for the last few weeks!”

With that Scootaloo lunged downwards, excitedly planting her muzzle on Sweetie’s pussy, playfully kissing and sucking away at it. Occasionally she’d stick her tongue out, teasingly poking it down into the folds. Her hooves stroked the insides of Sweetie’s spread legs, her eyes flitting between Sweetie’s privates and her face.

Sweetie was starting to feel very uncomfortable. But it wasn’t Scootaloo’s advances that were making her feel so. It was the fact that she was starting to enjoy said advances. Scootaloo’s tongue ran across her nethers, her lips occasionally puckering to kiss and suck at her clitoris.

Sweetie didn’t know where to look. If she looked to the two adults, she’d surely be reprimanded by her sister. But she couldn’t face looking at Scootaloo, the little orange filly that was now almost entirely unrecognizable - the strange attire, the sexual ability no filly should rightfully have, and that lustful fire in her eye that looked like it would never go out.

Rainbow leaned in towards her friend.

“Hey, Rari, you got a sec? ...In private?”

Rarity nodded, encasing the two in a blue bubble of magic.

“Sound barrier. The little ones won’t hear a thing. What’s on your mind?”

“Well…” Rainbow started, surprisingly bashful in her tone. “Don’t you think Sweetie maybe isn’t cut out for the whole pet thing? I mean, Twilight very specifically said the pet relationships were formed when both parties were entirely willing, and I can tell Sweetie isn’t fully on board with this…”

She directed her attention down to the two fillies, Sweetie holding one of her hooves over her chest, her eyes desperately darting around the room. Rarity gritted her teeth slightly, before directing her attention to Rainbow.

“Honestly darling, I think you're reading a little too deep into things! I can assure you she is fully on board with everything I suggest to her - she’s just a little slow to take to it. This is her first interaction with another filly, so no doubt she’s just nervous. But, if I may politely remind you of something - who provides your Pet with the finest attire and gear that money can buy, for free? It’s me. So, as friends, I would graciously ask you don’t make such wild accusations about my dearest Sweetie, okay?”

And with that Rarity terminated the bubble, unmuting the world around them.

Suddenly Scootaloo withdrew from Sweetie’s pussy, her face awash with confusion. She hopped up to her hooves, scurrying over to Rainbow Dash.

“Master? Why isn’t it working? Normally this technique you taught me makes all the female Wonderbolts cum really quickly, but its not working for Sweetie! Am I doing it wrong?”

Rarity found the genuine concern in her voice fairly admirable. Now that was the kind of tone a worried Pet should take with their Master. Rainbow tousled the flustered foal’s mane, dotingly reassuring her.

“Don’t worry Squirt, some mares just take longer to climax than others! Maybe you just need a little more practice! And that’s absolutely fine, you can practice on Master as much as you like! But you know, we should probably get going. I promised Thunderlane I’d catch up with him to help with some exercises, and the little one will be coming along to help out too.”

Climbing up from where they sat, Rarity showed the two ponies to the door, waving them off with a cheery smile. As the door shut, her focus shifted - back to the timid little filly sat on the floor, her pussy still moist with saliva.

“You know what you are? A disappointment. I've given you a wonderful opportunity - the opportunity to have purpose in life. Little colts and fillies don’t get anywhere without their siblings helping them along. Twilight came back from her travels, and she showed me the way our culture should really work - fillies and colts having purpose, serving their elders. She showed us all how it should work. So it’s only a matter of time until this is the new normal. And you will find your place in it. It’s not a matter of if, it’s a matter of when. And what do you do for me, when I give you this opportunity? Squander it. Humiliate me in front of my friends. You looked pathetic, and they both knew it. But things can still be set right. You just have to learn. And if you won’t learn by your own volition, I’ll have to make you learn.”

She stepped forwards, grabbing Sweetie Belle’s tail. Not in her magic, in her teeth. Through the house they went, coming to a stop at the flight of stairs to the basement again.

“Second door.”

Rarity didn’t have to say any more. Sweetie descended the stairs, coming to a stop in front of the new door. Pushing it open, the door creaked aside. In she stepped, engulfed by darkness. A minute passed before Rarity came in, in which time she’d collected a stack of gear and attire, none of which Sweetie could clearly see in the darkness. But regardless of whether or not she could see it, she’d know what it all was soon enough, as she heard her Master undoing the first buckle.

VIII: The Cell

Sweetie’s eyes jerked open with a start as she jolted awake. No sooner had she opened them, though, she scrunched them shut again. The room she resided in was suddenly purest white, the uniform, padded walls bathed in the stark glow of a massive white light bulb in the ceiling, just above the sturdy door. A thick piece of black glass in its centre was the only island in an ocean of white. The piercing light shone down on her, creating dancing reflections of light across her frustratingly tight latex.

The corset around her chest and belly was tight enough to make breathing tricky if she found herself in the wrong position, so movement had to be kept to a minimum - not that she could go anywhere, even if she wanted to. The little filly was completely immobile, with her latex-clad rear legs humiliatingly spread open by a thick, cold steel bar. Her front legs, meanwhile, were bound across her chest with three rigid straps, none of which had locks that Sweetie Belle could make out - though from the clanking sound that rung out behind her when she shifted against the wall she laid against, it was fairly apparent the padlocks rested over her back.

Concentrating her inner strength, Sweetie focused all of her magical energy on the padlocks. She'd never tried using her magic before this point - its power was so weak it would've certainly been useless. But she was truly, truly desperate. She knew the padlocks were Mistress’ choice, and she knew Mistress would be mad if she discovered her little Pet had been trying to break loose - but in that moment Sweetie didn’t care - she needed to get out of this mind-boggling discomfort.

Sweat beaded across her brow as she focused her effort, slowly running down her face and pooling under her chin. She squeezed her eyes shut, clamping her little teeth down on the impractically large ball gag Mistress had so lovingly thrust into her mouth. The rubber left an unpleasant taste - in sharp contrast to the embarrassingly blissful pleasure she now felt whenever her Mistress rammed it into her mouth.

Sweetie’s focus gave out. A dull moan seeped through the rubber ball, half of frustration and half of relief - akin to the sigh of ease after carrying something painfully heavy. Why had her magic not succeeded? Sure, it was pitifully weak, but the padlocks hadn't even moved.

Suddenly the reasoning became fairly obvious. Looking up, Sweetie saw that the black latex around her chest and legs also encased her horn, leaving only the very tip poking out, as if to mock her - teasing her with how close freedom was, yet how far away it was as well.

“So Little Missy, whatever are we up to?”

Sweetie Belle froze, her eyes wide as she realised her Mistress had been watching all along. The door swung open without a sound, before Sweetie Belle’s Mistress sauntered into the room. She carried herself with stunning grace, floating across the room like a breeze, her gorgeous hips swaying from side to side as she moved - a petite saddle bag bouncing slightly atop one of her flanks with each step. Closer she walked, taking each step with an almost painfully slow deliberateness, leaving Sweetie Belle wincing slightly at the agonizing waiting.

“So, my little Pet, did you really think you’d be able to tamper with Mistress’s loving gifts? You've never tried to use your weak magic against me, but the one time you try it, I've taken precautions to stop it? How funny.”

Sweetie Belle gulped, her eyes shifting desperately left to right as her Mistress sank down to her eye level - those eyes fiery, that smile wide.

“I know you didn’t think that. At least, deep down. You may be many things, my Pet, but stupid isn’t quite one of them. Naive, maybe, rebellious, definitely, but stupid, no. Which makes me think you did this deliberately, knowing Mistress would catch you. And that can only mean one of two things. Either, you wanted to get caught and be punished further, like the naughty little slut you truly are, or...”

The fire in her eyes burned even brighter for a split second as she leaned right into Sweetie’s face,

“You were trying to mock your Mistress, trying to be a little rebel, trying to be defiant. And if it’s the latter, well, you already know that would make Mistress very, very angry.”

Rarity stared deep into Sweetie’s eyes, unblinking, watching the flustered filly fall apart, the sweat now pouring from her brow.

“So, which was it, Pet?”

Her smile tapered off as she slowly pulled away from Sweetie’s face, returning to a standing position, her imposing form blocking out the light of the bulb. Slowly though, the smile grew back, even more confident and nefarious than before. Sweetie shuddered. She was in real trouble now.

“Tell you what. If it was option one, I’ll forgive my little Pet, and maybe even give her a little treat for embracing her punishment. Would you like that?”

She looked down on Sweetie as she nodded madly, the padlocks over her back and the collar around her neck jangling noisily.

“But, if it was option two, well, it only seems fair your punishment gets a little worse. If it was option one, say the phrase, ‘I love my Mistress’. If it was option two, don’t say anything at all.”

The giddy joy on Sweetie’s face slowly melted, falling away into a gaping chasm of despair, only to be replaced by black horror.

“I love my Mistress! I love my Mistress!” Sweetie shouted again and again, desperate for that blissful approval. But to no avail.

The firm rubber ball gag served one purpose, and served it well.

The only sounds that escaped Sweetie’s lips were a fuddled mess of syllables and moans, unintelligible to all but the one making the sounds. Rarity sighed to herself, breathing out loudly through her nose.

“Very well. You disappoint me. And to think we could’ve made progress.”

Suddenly sparks of magic flickered from her horn, two clouds of blue energy slowly rising from the saddlebag - drawing out two small, fat vibrators. Without another word she moved them through the air, slowing down as the tapered tips came to rest against Sweetie’s exposed pussy and asshole. Sweetie looked up at her Mistress’s eyes, shaking her head in pleaful desperation. Rarity responded by shoving the two vibrators as deep into her body as they could physically go.

Without breaking eye contact from the flustered little filly, Rarity drew another object from the saddlebag - this time a thick black blindfold. Effortlessly Mistress locked it in place behind her pet’s head, whilst simultaneously flicking the two vibrators into life. A quiet, constant buzz began to fill the room, along with the uncomfortable squeaks and moans of the filly that the buzzing vibrators rested inside. With the thick blindfold obscuring everything from view, Sweetie could only make out the sound of her Mistress walking away towards the door.

And with that the door slammed shut, leaving Sweetie alone with her thoughts and feelings as the two vibrators buzzed away inside her, the need for an orgasm that would never come building, and building, and building...

IX: The Point Of No Return

IX:The Point Of No Return

The birds merrily sang to one another in the trees above Rarity’s head. The sun beamed down on Ponyville, just another idyllic summer day. The saddlebags on her flanks bounced with each step as she meandered from store to store, stocking up on important goods. The bell above the door chimed as Rarity entered her last stop on her list. The Post Office. The clerk looked up at the white unicorn that approached.

“Hello Miss Rarity,” called out the clerk, grinning and waving.

“Hello there my Dearest! It’s a simply gorgeous day, is it not?” Rarity cooed, approaching the desk, suave as ever.

“It certainly is!”

The clerk leaned down beneath his counter, rummaging round until he found the large package he was looking for, labelled with Rarity’s name. Lifting it atop the counter, Rarity thanked him.

“So, Miss Rarity, tell me, is this little parcel something for your sister? Are you getting in on this ‘Pet’ idea Twilight’s been telling everyone about?”

Rarity smiled as she watched the excited expression grow on his face. Why hide it now?

“Yes it is, Dear. Why do you ask?”

She expected some kind of chastisement.

“Because I’ve seen so much ‘special gear’ being posted here to Ponyville residents over the last few months! Stuff from all over Equestria! Ornate jewelry from The Crystal Empire, industrial gear from Yak-Yakistan, even some strange perverse ‘toys’ of some sort from Changeling Hives and the Dragon Lands! Ponies are really getting into the Princess’ ideas!”

Rarity smiled, delicately placing the parcel in her saddlebag.

“Well, she is a Princess, after all, you can’t help but love her!”

With that, she turned back towards the door, waving the clerk goodbye, before heading back home.

* * * * *

The door of the Boutique creaked open. Rarity stepped inside, shutting the door again with her magic, before letting her saddlebags slide from her rump and drop unceremoniously to the floor. She let out a sigh of relief as the spell she’d cast over her body dissipated, her vast shaft and testes reappearing between her legs. Sure, she could just magically rid herself of the cock and recreate it upon returning home, but she liked the idea of hiding such a tool in plain sight. It made her feel powerful.

Leaving her bags by the door, Rarity trotted through the house towards the stairwell. Down she went, stopping in front of the second door, listening for a second before pushing it open. There she was, her little pet. Sat up against the far wall where she’d been left, the gear still locked tight against her, the two little vibrators still working their magic. The poor foal was a mess, her mane scruffy, her face bright red, her hind legs twitching madly as her body tried again and again to cum, with some cruel external force blocking it every time.

With a flash of her horn, the two vibrators shut off, sliding carefully from her holes. Another flash and all the locks that had held her in place were freed: the straitjacket slipping away, the spreader bar unlocking, the ball gag and blindfold slipping from her face. The latex still clung to her fur and her horn, but at this point Sweetie didn’t care about that in the slightest. The little filly dashed over to her Mistress, tightly hugging her leg, though her own wobbling legs gave out beneath her once or twice on the way.

“Thank you so much for letting me out, R- Mistress! Thank you thank you thank you!”

She started to feverishly kiss her Sister’s hoof, lost in desperate adoration. Only when Rarity patted her head did she stop, looking up into her eyes.

“M-Mistress, how long was I in here for? My body feels so sensitive…”

“Long enough to learn your lesson, hopefully," Rarity replied, "...and long enough to realize how much your Mistress cares for you. All those hot dinners didn’t cook themselves.”

Sweetie began to squirm awkwardly, clearly trying to find a way to ask more of her sister.

“Can I-... I mean, can Pet get out of this latex too?”

“I’ve already been generous enough to let you out of here so soon… don’t push it. Come with me. I have work to do.”

The two unicorns ascended the stairs, stopping in the tailor room. Rarity took her seat at the sewing machine, and began to bark instructions at Sweetie to grab materials and tools from around the room. Much to her pleasant surprise, Sweetie actually did so, running (albeit slowly atop her wobbly legs) around the room, getting the supplies she was instructed to. The array of materials began to pile up on Rarity’s desk, until everything she needed was together. Setting to work, she occasionally looked over her shoulder to see Sweetie sat awkwardly at her side, unsure whether or not she was free to leave or if she had more to do for her Mistress.

Rarity felt her cock twitch as she looked at the gorgeous, latex-clad foal.

“Come now Sweetie, slide yourself under the desk. Mistress needs to concentrate on her work.”

She didn’t need to say it twice. The little filly maneuvered herself under the desk, between Rarity’s legs, her face flushing as the rapidly engorging tip brushed against her cheek. Watching the cock rapidly stiffen, she took the tip into her mouth, holding the head for a few seconds, running her tongue along the various ridges and bumps of its profile. It caught Rarity off guard when that little tongue poked against her urethra, slowly stretching her open. As she fed the first piece of fabric into the sewing machine, she guided her Pet’s head forward with her magic, gently encouraging the filly to sink the cock deeper and deeper into her throat. The mare was still rather slow and nervous around her Mistress’ cock, which was a shame. However, Rarity could sense that Sweetie was almost completely converted. She just needed one more hard push to send her over the edge, and from that point on Rarity would really have her own perfect Pet, the poster child for this new culture. Rarity would be the talk of the town.

She continued to work on the outfit, though she found herself really rather distracted. It wasn’t so much the physical sensations of Sweetie’s warm throat tightly holding her cock, it was the thought of how close this little filly was to finally being her Pet. She couldn’t wait anymore. She had to finish the process.

Sliding her chair back, she climbed onto her hooves, picking Sweetie up and throwing her over her shoulder. In an unexpected feat of strength, she carried the mare up the stairs, stopping outside Sweetie’s door. She barged the door open, stepping inside and throwing Sweetie onto the bed. The foal sank down into the soft duvet and mattress, looking up at her Sister with a mixture of nerves and undeniable lustful excitement. Without so much as a word Rarity leapt up onto the bed, standing over her Pet. Her massive, fully engorged cock slapped down on her belly, dragging backwards towards her nether regions, the head coming to rest against her pussy lips.

She had denied Sweetie the sensations of her mammoth cock inside her vagina for all this time. Waiting for the right moment. And the right moment was now.

Sweetie opened her mouth to speak, but Rarity slammed her hips forwards at full speed, burying her entire length in Sweetie’s pussy. She yelped in shock, stunned as her abdomen bulged outwards as her Mistress’ cock made room for itself inside her. Sweetie mewled in pathetic delight as Rarity withdrew all but her tip, before slamming the full length forwards once more. Out bulged her abdomen again, rapidly flattening out as Rarity withdrew.

Rarity dropped down from her hind legs, pinning her full weight across Sweetie’s body as she relentlessly bred her vagina. The entire bed rocked back and forth with each powerful thrust, dull thuds filling the room as the headboard smashed against the wall. Sweetie’s tongue lolled from her open mouth, moaning loudly to herself like a feral animal, urgently shifting her hooves from gripping her Mistress’ sides to digging into the duvet they laid on. The latex would squeak occasionally as Rarity’s body rubbed against her sisters, adding to the chaos of sounds emanating from the pair.

As Rarity rocked back and forth, breathing heavily to herself, she leant down next to Sweetie’s ear, pressing her mouth against Sweetie’s neck. She held there as she thrust, before pulling away to look at the heavy love bite she’d left behind. As suddenly as the whole event had started though, she suddenly pulled out, slapping her vast, slick cock down on Sweetie’s belly again.

“..N-now,” Rarity gasped between deep breaths. “Be a good little Pet and close your eyes. Mistress has a surprise for you.”

Partially out of respect, partially out of an urgent want to continue the sex, Sweetie clamped her eyes shut, taking in a deep breath as she felt a sheet of latex positioned over her muzzle and eyes. She listened as Rarity rummaged through Sweetie’s cupboards, before evidently finding what she’d been looking for. Whatever it was, it was apparent that her older sister had the confidence to hide sex toys in Sweetie’s room for later use. The filly found that both humiliating and deeply arousing. She tried to listen for more sounds, but they’d stopped for the most part. The only noises she heard now were those of Rarity climbing back onto the bed. Her cock pushed against her pussy again.

The sheet of latex was thrown to one side. Sweetie looked down to see what Rarity had got, but she needn’t have looked. She felt it soon enough. Around her cock she’d strapped a large, bump covered band, effectively tripling the thickness of her already impressive medial ring. And there, teasing against her ass, was a thick strapon attached below her ‘real’ cock. The thing was an all black cylinder with no features, just a tapered end. Whilst the dildo was a good half the length of Rarity’s cock, it was easily twice as thick.

As Rarity pushed her cock deeper into Sweetie’s vagina, she slowed as the tip of the dildo met her asshole. She drenched it in copious amounts of lube, and the numerous anal sessions the two had had over time helped her asshole open up rather quickly. The mare gasped as both the cocks lodged themselves inside her, eventually bottoming out as Rarity’s crotch smacked her buttocks. Back she went, the dildo popping free of her asshole as more and more of her cock slid out. Back in she went, the dildo pressing past her puckering asshole.

As she fell back into her pattern, the original speed quickly returned. Rarity dropped back down to completely pin her sister, basking in the little gasps and moans she let out every time her dildo pulled free of her ass, leaving her little ponut to wink and pulse with excitement until she pushed back in. The unicorn whispered into her Pet’s ear.

“You know, my Pet, the magic I can wield is so much more powerful than you’d ever have thought. These balls of mine are actually inert, my magic seed could never impregnate a mare. Or at least, that’s the way it once was. But you know I have friends in high places. Even as we speak dear Twilight is developing a fertility potion to allow inert seed to become potent again. Maybe, if you’re a good little Pet,” She teasingly slowed, before slamming her hips forward again, “...I’ll take the potion, once it is finished. You would like that, wouldn’t you? To be knocked up by your own Sister? Your own Mistress?”

Rarity pulled back to look her Sister in the eye. Her face blushed profusely, her eyelids twitched, and her eyes struggled to focus on Rarity's, but she still managed to nod eagerly. It was time. Her balls had begun to twitch in anticipation as her need to climax built. Continuing to thrust, but still picking up speed, Rarity looked down at her sister again.

"Do you want to cum, Pet?"

Sweetie urgently nodded, almost surprised she would ever be allowed such sweet release.

“Then tell me, who am I?”

"You're my Mistress!"

Good start.

"And who are you?"

"I'm your Pet!"

Getting better…

"And what are you now?"

"I'm Mistress' object, that only lives to serve her!"

"...Good girl."

And with that, Rarity’s horn flashed, undoing the collar that had been locked round her neck all this time. With the magical barrier down, Sweetie’s body could release the orgasm - the orgasm it had been desperate to release ever since she went into the cell, for nearly a week now. As she did so, Rarity forced her cock as deep into Sweetie as it could physically go, that wonderful bulge reforming in her abdomen.

The two began to cum at the same time.

Both mares screamed out in bliss as Rarity’s seed launched from her cock, painting Sweetie’s womb white with spunk. Very quickly the high powered excess began to fire out from her pussy, splattering back messily over Rarity’s crotch and heavy ballsack. As they did, Sweetie’s head lurched backwards, her back arching as her own orgasm started. Cum launched up from her pussy, soaking into Rarity’s coat, and slicking her cock. The jets were accompanied by her moans and screams, massive for such a little mare. Incomprehensible sounds and words tumbled from her mouth as her legs twitched madly, each powerful spray of cum sending her body rocking like a boat in a storm. Rarity’s explosion of seed continued as well, her thick cock holding most of the spunk inside her hungry womb, watching as her belly began slowly expanding to accommodate the incredible load.

Rarity was surprised when her orgasm began to peter out first. Her powerful loads became a dribble as the last of her spunk left her body, but Sweetie’s orgasm continued. As Rarity pulled out, some of the errant spunk splattered against her chin, one shot even clipping the ceiling.

She really was pent up.

Taking a deep breath, Rarity stepped towards the bedroom door, ready to wash herself and rest up. But before she did, she stopped and turned, watching Sweetie as her orgasm finally started to subside. The exhausted filly moaned and gurgled to herself, her whole body shaking as seed cascaded from her gaping pussy. Most of the words that left her mouth were entirely unintelligible, but Rarity managed to make out a few of them:

“Thank…”

“...you…”

“...Mistress.”

It was done.

X: The Show

Three Weeks Later

Sweetie Belle’s Birthday

Rarity flitted around the boutique, carefully lifting outfit after outfit down from clothes rails and shelves, folding them neatly, before stowing them away in a multitude of boxes that covered the floor of the room. As each box was filled, she’d carefully seal it shut, before a bolt of black and white would shoot in through the front door. Sweetie Belle - magic collar locked proudly in place again, wearing two pairs of cute latex boots - would eagerly scurry into the house, picking up one of the finished boxes, before taking it out the front and loading it into the back of a small carriage. The latex wrapped around her horn was still in place, meaning magic was always going to be off the table now.

Sweetie had no idea what was happening, but that didn’t matter. Her Mistress was organizing it, and that way it was guaranteed to be perfect! Sweetie remembered her Mistress mentioning that they were getting ready for a birthday surprise for her, which filled her with excitement and glee as she loaded up.

With the carriage full, Rarity slipped out the front door, locking it behind her, one final box floating in her magic. The sun was setting as she placed the box down, opening it up. Out floated several bits of attire, some of which Sweetie recognized.

Standing tall, the little filly beamed as she felt that familiar saddle being placed atop her back again, the straps tightening around her midriff. Out came a mess of straps and locks, which Rarity slipped carefully over her Pet’s muzzle, closing it behind her head. With the rig in place, she attached a pair of blinders, before tapping Sweetie’s jaw. Faithfully she opened her mouth, moaning slightly as a wooden bit was placed between her teeth and fastened in place.

“Aren’t you a cute little workhorse?” Rarity cooed, stepping back to appreciate her work. As she walked around to the front of the carriage, Sweetie followed suit. There she saw two wooden poles protruding out, and several more heavy duty straps that would connect her to the carriage. Sliding into place, she smiled as her Mistress sealed her in, before widening her eyes as she felt something press against her nethers.

“Oh, that? It’s just a little treat for you Pet, to encourage you to pull faster.”

A long, tapered, cylindrical dildo poked into Sweetie’s pussy, the other end attached to the axle of the carriage. As Rarity climbed up on top, pulling at the reins she’d put in place on Sweetie’s head, the two set off. With each turn of the axle, the dildo was pushed forwards and pulled backwards, leaving Sweetie moaning with excitement and lust.

“To Canterlot, my Pet.”

Rarity settled back in her seat as Sweetie set to work. Progress was unsurprisingly slow, but Rarity wasn’t going to criticize. She had a big birthday show planned, and she didn’t want Sweetie tired before she’d even arrived. Instead, she took the slow pace as a chance to take in the sights of Ponyville.

Change was always quick there, but the grip Twilight’s ideas had taken was nothing short of impressive.

She spotted Applejack and her Pet Apple Bloom wandering down one of the roads, the little one pulling a cart of apples as Applejack bellowed out prices. Stallions and mares would walk over, buy an apple or two from AJ, before cooing over the cute little one, playing with her mane or running their hooves down her body. Rarity could occasionally hear moans and groans drifting through the open windows of houses, perhaps the sounds of some would-be pets in training?

Down another road, coming towards the edge of Ponyville, Rarity came across a little project she’d heard mentioned a couple of times. Well, it was one of Pinkie’s projects, so make that a couple of thousand times.

A new store, with its sign being put in place over the door. It read

Pinkie Pie’s Pet Pony Party Parlor

Rarity had to admit, a Pet pony daycare was a fairly genius idea, and who better to run it than the friendliest pony in Ponyville? But with no sign of the owner in sight, the two simply continued on for Canterlot.

Now, Canterlot would be an interesting one. Sure, Twilight was influential, but her sphere of influence didn’t quite hold Canterlot the same way it did Ponyville. As a result, Rarity expected a little resistance from the day to day folk as she crossed the city boundary. Sure enough, she listened as gasps of shock rose up from passers by, stunned at the sight of a filly in such compromising attire, being used in such a way.

But Rarity wasn’t worried. Twilight’s messages may not have begun to influence the Canterlot elite yet, but Rarity had a little more clout among the posh ponies. She’d been a trendsetter before, no doubt she could do it again…

She called out to one onlooker as the two rode by.

“Please, my dear, don’t be so shocked! Pets are great for being assistants, for modeling, for stress relief...why wouldn't any self-respecting pony want one?"

Passing one, she quickly reassured another.

"Honestly my Dear, a beautiful accessory like this is just what a suave sophisticate like you needs!"

As she moved past each pony she spoke to, she listened as their shocked gasps morphed into murmurs among one another. It was great to be influential…

Especially as she rode into the red light district.

Whilst the average Canterlot resident knew little of her work, the underground red light scene was starting to catch word in a big way. She’d had several visits to her Ponyville boutique from Canterlot ponies, looking to purchase some of her special wares. But this was her chance to take her work from small time to big time. Turning one last corner, there it was. The largest building in the red light district, an events hall, whose sign outside read

The Canterlot Night Hall: Only the finest, most upstanding events.

Everyone knew that wasn’t true though. And below the main sign, in just as large text

for one night only, Rarity’s Latex and Leather Line!

They were lining up out the door. Perfect.

Turning down a quiet alleyway beside the venue, Rarity tugged at the reins, bringing her tired pet to a stop. She climbed down, removing the slick dildo from her vagina, before undoing all the straps that bound her to the carriage. Opening the side entrance, she instructed Sweetie to unload the carriage. As she did, Rarity peaked her head through the curtain. Every seat was occupied, every single one of them facing the long, well lit runway in the center. Turning back, Sweetie was dragging the last of the boxes into place. She stopped, trying her best to catch her breath after all the manual labor.

“Alright, Pet, I’ve kept you in the dark long enough. You’re a gorgeous little filly, and so your Mistress has organised the perfect birthday celebration for you. You get to show your pretty little self off, and you get to model all of your Mistress’ designs that you love to wear! Now, each box is numbered. Go find Number One, and get yourself dressed up. Then I’ll explain to you the rules of the evening.”

Sweetie began working through the boxes, searching for the one in question. There it was. Pulling it open, she quickly removed the contents, slipping into the outfit. It was a fairly formal piece of attire, dressing her up to look like a fairly smart receptionist. The stockings and skirt were all very nicely designed, with that seal of Rarity quality.

As she finished getting dressed, she turned to show herself off to her Mistress. She was overjoyed to see that smile of hers.

“Wonderful, darling. But I’m afraid there’s one little thing.”

Her horn flashed, and the collar clasped around her neck fell to the floor. Sweetie was stunned.

“You see, Pet, a receptionist wouldn’t be wearing a collar. It’s just not a part of the style. But that’s not the only reason. You see, there are a couple of caveats tonight. Rules. For starters, no orgasms. But I don’t want my own magic to be an influence. I need to see that you alone have the strength of will not to cum for your Mistress. And just to make it that little bit harder…”

Without stopping, she floated two small vibrators into place inside Sweetie’s holes, clicking them both on to a slow speed.

“If you cum before the show is over, there will be serious repercussions. I thought of what would be appropriate for a long, long time. But you see, this show is very important to me. This will make or break my career. So if you fail me, I think it’s only appropriate that you suffer for it.”

Sweetie gulped. Mistress’ smile had gone. This was serious.

“Also, one final caveat. You’ve walked runways before, but rarely were you inhibited in any way. Tonight will be different though. So, for every time you trip, you will lose your free time on one day of each week. Fall once, and you lose your free time on Monday. Twice, Monday and Tuesday. You get the idea. The cell will be waiting for you if you ever fail me. Don’t fail me.”

With that, she smacked Sweetie’s rump as the curtains suddenly drew open. This was it.

“It's time for your moment in the spotlight. Get walking, Pet.”

As Sweetie walked out on the runway, all the lights were on her. Blindingly bright, they took her back to the lights of the cell. But whilst the cell was deathly quiet, this place was filled with clamor and applause as ponies watched her walk. Timid at first, she quickly picked up her pace - not out of confidence, but because she knew Rarity was watching.

She reached the end of the runway. She looked down at the ponies that watched her, smiling to herself as their eyes dug into every inch of her body. Her stunning mane, her supple legs in those black lace stockings, her ample rump in that form-hugging skirt. Mistress had made her beautiful.

Invigorated by the thought, she gave the crowd a twirl as she turned back towards the curtains. Her skirt flipped up slightly, the ponies in the front row giving a mighty whoop. Perhaps they just liked the view, or perhaps they’d caught a glance of Rarity’s special inclusions, buzzing away inside her?

Disappearing backstage, she beamed up at her Mistress as she began to disrobe, eagerly stepping into the second outfit that was presented to her. This one was a maid’s outfit, similar to the one she’d seen Scootaloo wearing. Actually, it was fairly apparent the two were identical. In fact…

As Sweetie slipped into it, the whole garment smelt, odd. After a few seconds, it clicked. The whole thing stank of dried cum. This was actually Scootaloo’s outfit.

“Don’t worry, Pet. The outfit is in perfect condition, despite the smell. None of the crowd would know, unless they climbed up on stage and sniffed you.”

With that, out she went again. Sweetie felt a lot stranger this time than she had before, the stink of cum rapidly filling her nostrils. With each step more of the smell seeped into her, slowly beginning to cling to her fur. Strangest of all, it was a smell she’d learnt to love, and as such she was concerned her appreciation was starting to show behind her. Sure enough, as she twirled at the end of the runway, she saw a small trail of her own cum along the walkway. Hopefully none of the onlookers would see it though. Wolf-whistles and cheers rose from the crowd as she sauntered away again, her hips swaying with each step, shaking the frills of her dress in a pleasing way.

Back and forth Sweetie went several times, showing off the various day to day ‘Pet Outfits’ Rarity had lovingly designed. Each was met with whoops from the crowd as they progressively became tighter and tighter, revealing more and more of her body.

Sweetie returned again, slowly removing the ‘Farm-Hand’ outfit. As she did though, she saw her Mistress was holding up something similar, but at the same time, very, very different.

It was the workhorse outfit she’d worn on the walk to Canterlot.

“My dear Pet, that’s the last of the ‘day outfits’, but that doesn’t mean the show is over. We’ve still got the ‘night attire’ to demonstrate,” she said, leaning in, “and it’s bound to get very, very interesting.”

Rarity stood back as Sweetie worked her way into the gear. Looking back over the boxes, there were only a few outfits left, all of which were likely to really get the crowd going…

Fixing the blinkers and the bit to her Pet’s face, Rarity watched from the darkened backstage area as her pet strolled out onto the stage. The crowd was stunned, with Rarity noticing a few stallions towards the back trying to surreptitiously remove their stiffening cocks from their smart trousers. One of the more brazen stallions near the front already had done, his impressive tool in his hooves as Sweetie got closer and closer. Somehow though, he looked confident, almost as if he was inviting Sweetie to watch him, as if he was teasing the cute, flustered little Pet.

Rarity could feel her own pussy aching slightly as she watched her Pet spin around on the stage, and so she allowed one of her hooves to drift down to her clit, having taken the decision earlier that day to remove the cock - she wanted all her focus on her Pet. Gently she rubbed it as Sweetie moved towards her again, until she had a fiendish idea. Sweetie reappeared in the changing area, ready to remove her outfit. But Rarity had other plans. Beckoning the filly over, Rarity stood on her hind legs, positioning herself over Sweetie’s back - directly above the saddle. Atop the saddle was a handle, a thick knob that stuck out from the seat itself.

Sweetie moaned awkwardly to herself as her Mistress began to grind her pussy against the handle. She wanted to be the one that pleasured her Mistress, not some piece of clothing on her back. But still, if this was what Mistress wanted, Pet had no right to say otherwise. So, obediently she stood there as Rarity ground back and forth, until a warm, slick sensation began to trickle down Sweetie’s side.

As Rarity pulled away, so did all the gear.

“Two more, Pet.”

The first seemed simple. It looked like just two pairs of boots. It wasn’t that simple though.

The thigh-high boots were built in a similar way to high heels, but the angle was so extreme they were more akin to a ballet dancer on their points. Those heels must have been eight inches. Easily. She’d never be able to walk in those.

Rarity watched her Pet’s face turn gray. She knew the little filly expected to trip. But nonetheless, this was a part of the show.

Lowering each of Sweetie’s hooves into the shoes, Rarity watched the little filly wobble from left to right. This would be interesting.

“Off you go, Pet.”

Sweetie rocked out onto the runway, greeted by gasps of appreciation and rapturous applause from the crowd. A few more cocks had been whipped out in the crowd now. One had already cum.

Rarity watched as the filly teetered precariously atop the shoes. Now it was time to turn.

The crowd let out a collective wince and gasp as the foal toppled over, crashing to the ground in a crumpled heap. Rarity couldn’t help wince too, but more in frustration than concern. However, the gasps quickly stopped, morphing into yet more whistles and cheers. In the fall Sweetie’s back legs had slid apart, displaying her genitals to the crowd. The flash was only quick, so not everyone would’ve seen it. It gave Rarity an idea though. Clearly mortified by the error, Sweetie was quick to her hooves, making her way backstage again.

“I’m so sorry Mistress please I didn’t mean to I just couldn’t do it please don’t be mad at me I’m sorry-”

Rarity quickly cut the filly off.

“We’ll see, my Pet. Not long to go now, just one more outfit.”

Sweetie carefully freed herself from the boots as Rarity pulled out the last piece.

It was her birthday present, that cute little outfit she'd mischievously tried on against her Mistress' will, all those weeks ago.

This time, Sweetie was very, very slow to get into the outfit, asking for her Mistress’ permission to wear it first. When it was given, she was extremely eager, slipping into the leotard and socks with ease this time. She shivered with pleasure as the latex tugged at her fur, smiling as the collar came to rest again around her neck. She stopped to look at that collar again, the word ‘Pet’ emblazoned along the side. It made sense to her now.

Once the outfit was all on, Sweetie turned towards the stage one last time - but a hoof placed on her rump told her to stop.

“Ah, not just yet, my Pet. There’s a bit more gear for you first.”

Sweetie took a deep breath, standing still as the extra gear in question was put in place. That ball gag in her mouth, the blindfold over her eyes, and the spreader bar between her back legs. She knew all this gear well.

She felt the leash go taught.

“Walk, Pet.”

Rarity smiled as the crowd erupted into one final round of applause. Many were on their hooves, cheering and clapping as the Mistress and her Pet appeared on stage together. They whistled and called Rarity’s name as she curtseyed for them all, before encouraging Sweetie to bow her head too.

But before she did, she had spun Sweetie around. When she bowed her head, her ass was presented high in the air for all to see. The crowd was given the view of Sweetie they’d all wanted. Rarity patted Sweetie’s head, motioning for her to stay bowed. She pulled out the two vibrators, before placing her hoof on Sweetie’s clit again. The vibrators had been going constantly, so the little filly was very, very close. It wasn’t long until Rarity had finished her off.

Sweetie’s orgasm was loud and powerful, soaking many of the ponies in the front row. Whilst a couple seemed slightly annoyed, many were in love with the event, watching the little filly’s legs twitch madly as the cum continued to fire out. Sweetie quickly grew tired, but the orgasm continued, much to the elation of the crowd. Eventually though it did trail off, leading Rarity to take one final bow, before leading Sweetie off the stage. The show had been, all in all, a rip roaring success.

Sweetie’s legs wobbled as she waited for further instruction from her Mistress. She watched as two ponies appeared backstage, quickly coming to greet Rarity and congratulate them on the show. She felt like she recognized them, but couldn’t tell from where.

“Pet, could you please load these boxes back onto the carriage? Your Mistress has some business to discuss. Wait for me outside when it’s done.”

She watched the tired filly oblige her, pushing one of the boxes towards the back door. As she did, Rarity redirected her focus to the two ponies. Fine Stride and Dainty Boots, two of her favorite Canterlot designers.

“Miss Rarity, we simply adored the show… Now, we wanted to talk to you about a little business proposition to help your fashion line really take off in Canterlot.”

With the work done, Sweetie waited by the carriage for her Mistress. She was exhausted, but knew she still had to pull the carriage home. So, knowing it was to come anyway, she fished through one of the boxes, pulling out her workhorse outfit, slipping back into it.

By the time Rarity emerged, beaming, Sweetie was all but asleep on her hooves. A pat on the flank woke her up though.

“You did alright in there, Pet. Now, take us home, and perhaps then you’ll earn have earned yourself a bath, and perhaps even a night’s sleep in Mistress’ bed. And consider your punishment for the fall waived. Think of it as a birthday treat.”

Now it was time for Sweetie Belle to beam as she was fastened to the carriage, the two slowly heading off for home. Every step of the way Sweetie was thinking of her Mistress, basking in that wonderful mare’s glory.

Rarity’s work was done, and Sweet Celestia did it feel good.

III: Ask Your Friends

III: Ask your Friends

“...And then she sent me out the door without a second thought! Not a thank you or a goodbye or anything! She’s been acting so strange the last few days, and it’s starting to freak me out… have your sisters done anything like that to you two before?”

Apple Bloom and Scootaloo both looked at one another, mouths agape as the three sat in the middle of the hectic classroom. Cheerilee hadn’t arrived to take roll-call for yet, so the room was bustling with chatter.

“Ah’m sorry Sweetie, ah can’t say I’ve ever seen Applejack actin’ that way before! It’s certainly a strange one! D’you think maybe that she’s still just mad about the whole ‘birthday present’ thing? Like, she was setting up a treat for you and you spoiled the surprise… perhaps she’s still getting over that…”

Unsure of Apple Bloom’s answer, Sweetie looked over to Scootaloo.

“I think Apple Bloom might have a point there, Sweetie. Ponies get cranky all the time, and perhaps Rarity’s just getting super cranky. I’m sure it’ll pass!”

Sweetie’s face turned red with shame as she spoke again, her voice a stammering whisper.

“B-But what about the, the paddle and the games and stuff…”

Scoots and Apple Bloom looked at one another, still unsure quite what to say.

“Perhaps it’s just a part of getting older Sweetie! Maybe that’s just what mares do with their siblings - you know, a coming of age thing! ...don’t you think, Apple Bloom? Apple Bloom?”

The little pegasus dug her elbow into her friends’ side when she didn’t respond.

“Oh, er, yeah! Ah mean, AJ’s always mentioning how ah gotta shape up my body as ah come into maturity… she says fillies are expected to help their elders, so they’re gonna help me get to grips with the rugged farm life… Is that the kinda thing you mean?”

She darted a hopeful glance back towards Scootaloo, who’d scrunched up her face, clearly not entirely happy with the response.

“Yeah, I guess. I mean, I get that sort of thing every now and then - Rainbow’s started giving me funny looks, plus she’s asking me all sorts of questions about how I feel about myself… Long and short of it Sweetie, big sisters do weird things, but they always mean well! Always trust your elders!”

Sweetie slumped back in her chair as Cheerilee pushed the classroom door open, the room slowly hushing into silence. That wasn’t as reassuring as she’d perhaps hoped it would’ve been.

V: Judgement

The clamor of the classroom. As ever, every colt and filly was distracted in their own little sphere, far too busy with their own situations to notice anyone else’s. Sweetie Belle had never really stopped to appreciate that before, but now…

She sank further and further into her seat as Scootaloo and Apple Bloom stared at her. She held her shoulders in, keeping her hair flush to her neck. Despite her best efforts to hide it, though, the collar clamped around her neck was obvious, the bold black leather standing out for all to see against her soft white fur.

“Sweetie, why in Equestria you wearin’ a dog collar? Is that some kinda crazy new fashion thing your sister’s comin up with? And why’s it so thick? That thing could hold a timberwolf at bay!”

Sweetie recounted the events of the night before, her words quick and hasty, tumbling from her mouth as she blurted it all out. With each passing sentence she sunk further and further into her chair, practically vanishing beneath the desk.

“It’s part of a new game Rarity’s started playing with me. I don’t think I like it… well, I do, it makes me feel really good, but I don’t like it. She bosses me around and makes me feel really strange. I think she’s hoping I’ll warm to it… do you girls really think this is normal behavior?”

Up until this point, Apple Bloom had been asking all the questions. But suddenly, Scootaloo burst into life.

“Oh Sweet Celestia, that sounds awesome! Honestly Sweetie, you should really just embrace it! Rainbow’s started playing games like that with me as well! Well, sometimes it’s me and her, sometimes it’s me and Soarin’... or me and Spitfire, or me and Vapor Trail, or me and Thunderlane...y-you get the idea! Such great games! That’s awesome that you’re playing too! I’ll have to tell Rainbow all about it! Hey, if the two of you play any other kind of games, you’ll have to tell me about them too! That’ll be super fun!”

As words poured from Scootaloo’s mouth, Apple Bloom and Sweetie Belle both just stared, dumbfounded. Where in Equestria had this new attitude come from? Suddenly Apple Bloom’s line of questioning had been directed away from Sweetie and on to Scootaloo, meaning Sweetie was entirely free of attention once again. As Cheerilee entered the class, Sweetie found her mind drifting, slowly clogging with more and more questions. Among them, though, two stood out to her: One, was she supposed to be enjoying all of this? And two, why did she feel so desperate to cum again?

Epilogue: The New Range

Rarity’s Ponyville boutique was packed with customers. The whole place was alive with activity, the hubbub of ponies going about their shopping. Rarity sat behind her counter, watching as ponies filled their arms with clothing for their own little Pets. It had been about seven months since Twilight first started promoting the Pet culture. Now, nearly every adult in Ponyville had one.

Filthy Rich was busy looking through one of the shelves, stocked to the rafters with sex toys of various depravities. His cart was already overflowing with goods he planned to get Diamond Tiara and her friend into, but he could afford plenty more. He glanced down as Sweetie sidled up beside him.

"Hiya! Find everything you needed?"

"I think I’ll be fine withou-"

"Do you want me to try out anything you bought? Best way to see how it works!"

"No, I’m fine without the hel-"

"You sure? It's only a liiiittle extra..."

The stallion’s brow flushed slightly, watching the little filly shake her rump provocatively. He glanced around the room as one of his hooves pushed against Sweetie’s pussy, his eyes awkwardly settling on Rarity.

"Sir, can you please stop groping the Store Pet? We have a private fitting room if you want to see her wearing the gear, and you're more than welcome to try her for yourself. You can do whatever you desire, but condoms must be worn and if you damage any of the attire, you have to buy it.”

Sweetie grinned to herself as Filthy led Sweetie to the fitting room, his cock rapidly stiffening between his legs - egged on by Sweetie playing with his ballsack as they walked. That little filly was learning well - sex sells.

As the two entered the private, ‘sound-proofed’ room and intense moans and slaps filled the store, Rarity leaned back, adding another score to the ‘Pet Fuck Tally’ she had in her journal on the desk. She sat back, listening to the gorgeous moans of her little Pet as she was stuffed with the fifteenth cock of the day, before turning her focus to back to the massive line of ponies ready to pay for their goods.
