Mystery Mare
"Is it just me," Rarity began, "or has Twilight been rather... 'hard to locate' after her coronation?"
The mane six, minus the aforementioned lavender alicorn (were they still calling them those?) were gathered for an impromptu lunch, initiated on account of Rainbow Dash has hungry and felt like inviting them to lunch. Rarity was never one to say no to an opportunity to sample day-fresh watercress sandwiches, and so she'd tagged along with the subject of her friend's disappearance weighing wearily on the back of her mind. Now was the best time to bring it up... but somehow, nopony besides her seemed to suspect there was anything untoward underway.
In particular, Rainbow Dash let out a loud yawn, her mouth still stuffed with vegetarian burrito. Then she went back to chewing, loudly chomping at the spinach wrap and its contents and downing them with an equally cacophonous sip from her orange-mango smoothie. This was Dash's third time going out to lunch this week, and if Rarity had been more honest than generous, she might have mentioned how her friend's stomach and flanks had taken on a little bit of extra pudge over the last while. But she wasn't, and so she didn't, instead settling for a plain, polite smile as she waited for Dash to finish her chomping and hopefully compose an answer to her inquiry.
"Hmm," came the reply at last, following another sip of smoothie. "Now that you mention it..."
Rarity leaned over the table, her eyes glowing like a new set of sequins.
"Yes?" she asked, her voice trembling with anticipation.
Rainbow Dash shrugged.
"Nah, nevermind. I was thinking of something else."
"Oh."
Rainbow Dash became preeminently occupied with her foodstuffs again, and so Rarity decided to direct her inquiries elsewhere.
"Applejack?" She hazarded a glance in the farm-pony's direction. "I don't suppose you've heard from dear Twilight recently? It feels like I've seen neither hoof nor hair of her since she was appointed Equestria's newest princess!"
Applejack had a fritter and glass of cider that threatened to occupy her attention as readily as Dash's food had her, but the '[POLITENESS]' attribute on Applejack's character sheet was higher, and besides which, she'd had a big breakfast.
Still. You couldn't tell somepony what you didn't know. Applejack settled for a sympathetic head-tilt and a shrug.
"Sorry, sug. I've been workin' a lot lately, but I ain't seen Twilight around much. It's probly nothin' ta worry about tho. I'm sure she's got a lot on her plate, bein' a princess and all."
"Hmmm."
Rarity took a moment to sample her tea—cherry chocolate rose, a house blend that was recommended by the barista. Somehow, through the rich overtones and savoury flavours, Rarity tasted the particular aroma of mystery.
It was time to investigate things of her own accord...
The Royal Castle in Canterlot, or just 'the castle', as Rarity had taken to referring to it in her head since beginning her investigation, would have on any other day been a delightful location for an outing of any type. Rarity could have spent hours patrolling the ancient, austere hallways and marveling over the various tapestries and stained-glass monuments to Equestrian heroes passed. She could have, in fact, spent the entire day marveling over her own image in stained-glass, although perhaps fussing over how they'd styled her mane, a little tacky, much more last century's fashion than anything contemporary...
But that was all idleness, and Rarity was here on a mission. She intended to locate her recently-royal friend, or her name was no longer rarefied.
An errant sniff at the air. The castle smelled mostly of oiled suits of armour and the erstwhile lingering of royal perfume. Celestia's scent was something like a bouquet of fruits mixed together on a summer afternoon, while Luna's was much more insidious and subtle, impossible to place unless Rarity was to douse her entire face in the stuff. Maybe just a slight hint of bluebells, or whatever star-light may have smelled like when bottled and sold?
Rarity poked around behind a few pieces of tapestry, lifting the old, worn fabric off the wall and peering beneath, in search of any clue that might point her properly in the direction of locating the missing Twilight.
Maybe she'd been spending too much time around Pinkie Pie—it wasn't exactly likely that Twilight would be hiding in a space barely large enough for a dust-bunny. Then again... you never knew what kind of forbidden powers royal magical energy might secretly contain. Rarity found herself looking over her shoulder apropos of nothing else, wondering whether the short gasp had come from herself or simply inside her head.
Now, if she were Twilight, or, more properly, Princess Twilight, at the behest of still-Princess Celestia, where would she be...
"Ah!" Rarity couldn't help but let out a little triumphant exclamation. She'd followed a hint of Twilight's lavender body-wash down a series of hallways, to what appeared to be a dead-end. However, when she explored the empty stone wall, and determined the lavender scent to be even more present, a minute or two of poking and prodding with her hooves and horn revealed, at last, a single brick of displaced stone, which slid inwards as she pressed it, and only a few seconds later, revealed the entire wall to fall away, folding in on itself until a dark, narrow passageway was revealed in the castle wall.
Though she considered herself something of an expert amateur investigator, Rarity nevertheless felt pleasantly surprised that her poking around had so quickly steered her to a proper lead. This was much better than the the 'whodunnit' party Pinkie hosted last month...
"Miss Twilight, worry not," Rarity said to herself, tucking a fetching summer bonnet onto her head and pulling it down over her mane. "Detective Rarity is on the case."
Rarity's horn began to glow a bright, shimmering purple, and the makeshift candle served to guide Rarity down the tunnel as it stretched out in front of her. She was so preoccupied with her investigation, and so certain she was only feet away from discovering the location of her claim, that Rarity didn't even hear the shifting wall fold back into place behind her. She was already around several corners when it closed, trapping Rarity inside her investigation until its conclusion, and the tunnel besides.
The only sound besides hooves on stone was Rarity's humming, a pop tune she'd heard but couldn't place the words to.
The first thing Rarity did, believe it or not, was look for clues. It is an important point of detail, however, that when casting a mental net to the sea of potential information, that your average pony-detective may so happen to forget the most readily available source of information is directly from the horse's mouth, so to speak.
That is to say, Rarity decided to ask the guards first. Surely if anypony was aware of where the princess and her royal charge had been, it would be the immobile fixtures of palace security, keeping watch over its empty and austere hallways like permanently in-place magical sentries. Rarity had heard rumours that if a pony guard moved even once during their eight hour shift, they were sent back for training on how to stand absolutely still without bothering anyone. How they went to the bathroom was anypony's guess.
"Excuse me," Rarity said to a pair of guards standing just outside one of the castle's many miscellaneous archways. "I don't suppose I could have a moment of your time?"
The two pegasi guards shared a look, no doubt attempting to give the appearance of an over-polished mirror in no hurry to answer the questions of particular ponies at present. Nevertheless, Rarity's manner was persistent, even if her questioning wasn't, and all it took was several seconds of silence hanging in the air, with Rarity gazing towards them, wide-eyed and curious, before the guards began to shift nervously and feel somehow causally implored to share the information that hadn't yet been requested of them. The pair shared another look, and the slightly larger of the two, the gruffer one on the left, gave Rarity a look up and down before nodding in a small and precise motion.
"Mmm," he said, a half-grunt, but at least enough to let Rarity know she wasn't immediately about to be escorted off the premises.
"It's rather a silly question," Rarity went on, her voice ringing like a bell of innocence and surreptitious information gathering, "but recently it's come to my attention that both princesses—that is to say, two of the three, I mean—Princess Celestia and her recent charge, Princess Twilight, have been—oh, what's the best way to say it—'missing'?"
The guards shared a third look, something along the lines of 'Is this one still talking?'
The gruff one nodded again, ever so slightly, and grunted.
"Well," Rarity continued, "I've been meaning to organize a sort of, royally-themed gratuity banquet—a kind of, big thank you, for the Princess—Princesses, that is—and all the hard work they do for Equestria."
Blink. The two guards shifted their eyes slightly in each others' direction.
"And so, I was just wondering—if it wouldn't be too much trouble, that is, not to put you out at all, really, I just need this little piece of information—if you'd seen either of them lately—and, if so, if perhaps you could let me know, ever-so-kindly, where that had been, please and thank you?"
It took sort of a few seconds for the guards to realize all the words Rarity had said were inside their ears—sort of like standing in a wind tunnel and waiting for the ringing to leave after the giant fan was switched off.
"Well," the guard on the left began, "Princess Celestia is always in the throne room first thing in the morning."
"To raise the sun," grunted the guard on the right.
Rarity's eyes went wide, brightened by the luminous scrap of information she'd already gathered.
"Yes," she said, "I'd expected as much. Nevertheless, that does leave the matter of where she might be located any other time..."
"Twilight and Celestia 'been in the study a lot," the left one said. "I mean... Princess Celestia. Uh. And Princess... Princess Twilight."
The look from the guard on the left was one of sheer panic. Rarity did her best to hide the smirk she got as a result.
"Psst," the one on the left said, far too loud to function as a surreptitious reminder. "We ain't supposed to—"
"Well, you gentleponies have been remarkably helpful. Thank you ever-so-much for your kindness. I'll just leave the two of you to the rest of your, uh... invigorating duty."
A sigh rang out of the pair in unison as Rarity turned and began to walk away. And though it would have been easier to simply stare at the floor in despondence, neither guard pony could keep their eyes to themselves as Rarity headed down the hallway, shaking her taut rump from side to side as though she were a model on a runway.
Let it be known there was a lot you could find out simply by being well-dressed and asking the right questions...
It took a while to figure out exactly which study the guard meant by 'study'. It turned out, when your favorite pupil's preferred pass-time was 'studying', there were a lot of 'studies' available, and, as a matter-of-fact, it occurred to Rarity that any cozy alcove with a book and a desk could technically fall under the 'study' umbrella. She devoted her search more so to congregations of books in cloistered off areas, and so spent no more than fifteen minutes poking about before she was certain she'd found her mark.
There was, for one thing, the preponderance of books, the ancient and dusty type of which Twilight Sparkle was particularly fond. There was the official-looking gold-embossed plate beside the door that said 'CELESTIA AND TWILIGHT'S STUDY: PRIVATE'. And, lastly, once she'd jimmied her way inside the room and shut the set of old, creaky doors behind her as quietly as she could manage, there was the partly-open book-case, poking out of the wall at an angle to reveal the not-so-secret-at-the-moment passageway. And another embossed plate that said 'EVEN MORE PRIVATE: KEEP OUT OR ELSE'.
"Perfect," Rarity whispered to herself gleefully. She did a quick survey of the room, scanning it for obviously evident clues but coming away with not much more than a case of dust-bunnies up her nose. It was the passageway, in fact, which screamed out to be investigated, and therefore where Rarity went after only a moment more, taking a last moment to chuckle at her own deductive abilities before frolicking down the dank tunnel. Before she knew it, Twilight's location would be revealed, and she'd be on her way back to Ponyville ready to make a report of her findings to all the friends who had been not-particularly interested in Twilight's whereabouts in the first place. Well, fie on them. A mystery was a mystery, and demanded to be solved of its own accord.
Still... it was quite dark in the tunnel. Even as Rarity's horn shimmered and repelled some of the skulking shadows, she wished she'd brought a proper light with her.
But there wasn't much more to it. She needed simply follow the way forward until she reached her investigation's inevitable conclusion.
It was just that sound that began to nag at her as she walked—aside the tapping of her hooves on stone, something like a wild animal, crying out in the distance, muffled through layers of palace architecture, barely a whisper through the walls. Rarity strained her ear, seeking to place the unique texture of the tone, but couldn't quite root it in anything she'd stepped hoof in recently. The sound grew louder as she crept forward, ever so slightly, until it was a little more than that first dampened yowl, something more certain and prolonged, a held vowel that stretched out like a summer afternoon. Rarity wished she could place it, with that and the song from before, her memory felt faintly like it was fully equipped for a full day of playing detective.
All the better to solve the mystery now and put things to rest them. Hmph. Rarity adjusted her hat, feeling important to look her best even in a sealed off stone tunnel. There was, from the look of it, a doorway not much further, and beyond that, the sure-fire certainty of an answer to conclude all the afternoon's wonderings.
The door, surprisingly, was unlocked. Rarity tested it with her hoof, feeling for a lock, but was startled when she found the knob turned freely. Slowly, careful not to let even the faintest click of a mechanism come into place, and with an utter slowness like the ages unfreezing a block of ice, Rarity slid the door open and peered past it. The words were already on her lips, something like a triumphant grin emerging as she stepped inside the musty room.
"Aha! I knew I'd find you here. Not so sneaky now, are we miss... miss..."
Rarity couldn't help but trail off. Her brain seemed to be shutting down in the regions responsible for coherent speech.
There was Twilight, alright. It seemed practically convention by this point to suddenly stumble in on one's friend in an untoward situation—certainly Rarity was no stranger to being in the middle of 'self-intimacy' when Sweetie Belle came barging in without so much as a knock, prompting for a hasty explanation and cover of excuses for why she was so sweaty all of a sudden... but there was a level of degree to that discretion, and Rarity felt all at once like her sensibilities for describing sexy activities and their related accouterments were insufficient.
Yet, she had to try. How was it best to begin?
Twilight was there. You could say that for certain.
Princess Celestia was there also. She was certainly... around. There was a lot of her, and she was round, largely, in places. It seemed absurd that Rarity went so often without describing that particular royal facet... that, seen from behind, Celestia could rival the size and shape of a sunset and then some. Rarity recalled she had heard ponies refer to the particulars of the royal posterior as exactly that—or, in slightly more uncouth circles, the famous Equestrian 'sunny-side up', which was a slang Rarity had stumbled her way around more than a few times before being taken aside by Applejack and given the correct definition, accompanied by furious blushing and an irrepressible set of giggles.
Oh, you could say there was the room, too. Rather small, stone walls, lit by torches... it felt a little like a 'dungeon', save the overall lack of ponies hanging from walls chained by their hooves. Though, as Rarity surveyed further, and her eyes continued to fall on her missing friend, at last located, though considerably compromised, it occurred to her that a set of chains wouldn't have been entirely out of place...
"Mmmph," Twilight murmured through her gag. Her blindfold meant only Rarity's voice could have keyed her in to the unexpected company, but whether she was reacting to that, or perpetually invested in her royal mentor's goings on couldn't be ascertained. It was quite an outfit she had on too, Rarity couldn't have imagined anything that dashing in Twilight's wardrobe—and yet, there it was, a clinging, shimmery, leather-looking getup that highlighted the curvature of Twilight's body, making her look much like a submissive pet on display for purchase. Rarity wasn't a complete stranger to the sort of getups worn in playful circles of this sort in darker, more private parts of Ponyville... but she'd never expected to see such an outfit on Twilight, let alone in the relative seclusion of a super-secret study, being attended to directly by Princess Celestia.
It was a gentle attention, just teasing, it seemed, and Celestia's hoof continued to bandy playfully about Twilight's exposed body, tracing lines soliciting shivers and more muffled moaning into Twilight's gag, which looked of a fine cloth crumpled and shoved into her mouth. Twilight's body strained against the electric-nothing, the tense tingles causing her to shiver each time Celestia's touch came around again. It was a sight Rarity wasn't entirely unfamiliar with, outside of the context of the participants, one she'd participated in herself, minus the audacity of the outfit and the added gag and blindfold... the simple shudders of a pony desperate for more affection, hanging precariously on the edge of an orgasm, dangling over the cliff but unable to be set free and fall downward into the ocean underneath.
"Oh," Rarity said. It felt a bit dull, all considered, but at least it was something.
Twilight didn't even turn her head, but Celestia did, and her smile was warm and reassuring as much as it was intimidating.
Rarity swallowed a nervous lump in her throat, wondering if she was still best to play detective or not.
"Well," Celestia said. She seemed to barely notice Rarity's sudden presence, to almost disregard it completely, still languidly running her hoof all over Twilight's exposed body, a line down her back, in circles over her chest, flitting between her legs and then drawing back when Twilight began to whimper. It took all of Rarity's willpower not to stare, and even then, she couldn't help watch out of the corner of her eye as Twilight thrashed perpetually in the mild restraint of her blindfold and gag.
That was about it, for what felt like ten eternities but was probably not longer than a minute. Rarity felt the lump forming in her throat again, and wondered if speaking quickly would prevent it from solidifying.
"It seems I may have come—er, arrived, that is to say—at a bad time." Rarity felt blush creeping into her cheeks, familiar when she was at home gazing on somewhat similar images in the privacy of her bedroom, but not as much in the proximity of one of her best friends or the Princess of Equestria's beside. Again, Rarity felt her eyes drawn to inspecting the royal backside from afar, attempting to verify for herself it was indeed as curvaceous as she'd be led to believe.
And though it was, after only a few seconds, obvious Celestia had noticed the staring, Rarity looked on obliviously, her head too hot and swirling to notice back. Too busy noticing backside to notice anything else.
"It is alright," Celestia said, somehow sounding motherly and composed even caught unawares in the middle of her sexual escapades. "I would say we were not expecting company, but the way Twilight left the door ajar indicates she may not have been adverse to receiving a visitor."
Rarity looked down at her friend, who, as at least her ears were unbound, surely had by now to have noticed who else was in the room. Her body seemed to thrash perpetually, and if it was in response to hearing her friend's voice in the room, Rarity couldn't tell. She recognized the look of proximity to ecstasy, and found herself wondering if she ought to sidle over to Twilight and join in the touching to help bring the poor thing over the edge. Her whimpers were constant, desperate.
"Um," Rarity said. Was it hot in here? It felt hot. Rarity decided she felt hot. Certainly she seemed to be sweating. Damper than she had been a minute ago. Between her legs certainly, if nowhere else. Er.
"I do not suppose you would be interested in joining us?" Celestia asked.
It was Rarity's first chance to notice—Celestia was definitely carrying a riding crop, holding it next to her head with the glow of her magic. It looked just a little wet, stained with sweat in the dim light of the tiny stone room.
"Um," Rarity said again. She all at once considered the notion that, while she hadn't woken up with any intention to satisfy her more lady-like needs, it had been over a month since she'd last entertained a stallion suitor, and even longer since she'd been in a mare's company. A long, long time since she'd gotten tangled in sweaty bedsheets with another body next to her, hooves searching and finding, mouths hot and heavy and panting as they sought to come together. The sensation of her entire body, tingling like electricity underneath her skin, the tender pull that made her heart beat faster and her legs quiver and a sharp jolt go right down to her clit. And even though nopony had touched her, Rarity found herself stifling a soft moan by clamping her teeth down on her bottom lip.
Celestia was still smiling. Twilight moaned through her gag.
"Well," Rarity said, taking care not to sound too enthusiastic, "it isn't as though I'd be entirely adverse to the idea... modern Equestrian expectations about monogamy have never made particular sense to this mare, all things considered..."
Oh, dear. Was she starting to speak in the third person again? That always happened when things got... heavy.
"I dare say Twilight looks as though she'd be interested in the idea as well." Rarity turned her head towards the quivering purple alicorn (they're still legally allowed to call her that once a day) and tilted sympathetically, even though there was no chance of her being seen. "Twilight? Dear?" Yes, her ears perked up, certainly, and she whimpered a little louder, even as Celestia was running the riding crop between Twilight's hind legs, no doubt smearing the wetness of her cunt all over her coat... "Mmm, I suppose that answers my question, without even needing to ask it. Still..." Rarity trailed off, hoof on her chin. "It has been quite a while... I trust there might be certain rules, were I to volunteer for participation?" Rarity eyed the riding crop again.
Celestia giggled and nodded softly.
"Indeed. I see you are no stranger to the implements at hoof."
"Not a stranger, per se, though we'd certainly enjoy getting better acquainted..." One last pang of conscience rang at Rarity's door before she threw herself unabashedly over the cliff-face. "Er... Twilight is, um... consenting to all of this, yes?"
Celestia tilted her head, grinning.
"Do you think I am the type to tie my student up against her will?"
Rarity looked from Celestia, the outline of her posterior visible even as she was standing from the front. To Twilight, who seemed to be arching her back in Rarity's direction, begging wordlessly for a third member to participate in their engagement. Rarity sniffed the air, and the unmistakable scent of sex drenched her senses, sending another powerful twinge between her legs, which she squeezed tightly together.
"Well... I suppose not..." Rarity said.
"You are welcome to wait until we are done if there is something you need my student for," Celestia said simply. "Otherwise, her attentions are required here for the time being."
"No, no, that's—I'd be delighted to join, that is. Absolutely overjoyed." Rarity batted her eyelashes demurely, blushing. "Really."
Celestia's smile broadened ever-so-slightly.
"Splendid," she said. "I am happy to have another participant. Let us get you properly outfitted..."
It occurred to Rarity around this time that, while they weren't used to seeing the Princess's magic on display that often, there was theoretically an entire library of arcane incantations she had mastered and made use of for at least a thousand years prior. Conjuring a riding crop was most likely, at the end of the day, a relatively trivial matter of magical focus. Twilight's outfit, therefore, didn't even need to have been made, though Rarity was loathe to admit her place as a fashionista could be supplanted by simple arcane summoning... but that was the truth, and it made just as much sense as Celestia's horn began to glow again, the air parting to make way for a shimmering magical rift. As Rarity watched, dumbfounded, an outfit to match Twilight's was manifest right in front of her, complete with the same shimmering material to highlight her curves... oh.
And a collar, too, now that she noticed it. Twilight just so happened to be wearing one as well.
"Oh," Rarity said. "My. I haven't worn one of these in... quite a while."
Celestia giggled. Her horn only shimmered faintly as she held the riding crop aloft, while the outfit and accompanying collar both hovered to rest in front of Rarity's hooves.
"It is nothing official, so you needn't worry about being bound afterwards," Celestia intoned. "Twilight is of course under a different set of encompassing restrictions, but for now, simply knowing she is not allowed proper release without her princess's permission should be sufficient."
Rarity nodded, noticing the sweat collecting on her brow and the continual tingle of the increasingly moist trickle coming from between her pussy lips.
"Yes," she said, "I'd surmised as much. I suppose you'd like me to, er... refrain from that as well, while I'm participating?"
Celestia nodded.
"Yes," she said. "That is more or less the fun of it." Another giggle, which sounded just slightly menacing.
"Very well," Rarity said. "I'll just, er... slip this on then..."
Celestia reached forward with a hoof. "Would you like some help?" she asked.
Rarity flinched back just a little, not out of real fear, but the tense, worried kind of anxiety that came about when you were only seconds from stepping into a set of horseshoes that mandated your behaviour for the remainder of the evening. Rarity was good at following arbitrary rules—her entire career as a socialite was based on it, in fact— but she didn't have a lot of practice in this arena, despite her romance novel readings, and it might end up being a lot harder than she initially suspected to keep her body from doing what it seemed natural and necessary to do when surrounded by sex smells that intense.
"Er," Rarity said. "No, that's... that's alright, really. Just give me a moment and I'll be all changed."
"Very well," Celestia said, sitting back patiently. "As soon as you have changed, we shall continue our instruction."
As if on cue, Twilight whimpered and thrust her hips into the air.
Celestia smirked.
"Feel free to take your time," she said coyly.
Rarity dressed with that urgency in mind—in a moment, she'd be joining her friend, and therefore could expect to endure more or less the same treatment alongside her. From the look of things, Twilight had been struggling here a while, and Rarity didn't fancy prolonging her torture any more than necessary—the same as she might hope from a friend in a similar situation.
The leather-like material felt tight and hugged her body in unfamiliar ways, but the moment she was dressed, Rarity felt the change in something at the back of her mind, a little switch that dictated her behaviour inside of doors and out. It just took the collar snapping into place, little studs circling around her neck, for the feeling to complete.
"Very nice," Celestia said, catching Rarity off guard. It felt like she was in the room all by herself, just for that moment. "Are you ready to proceed?"
Rarity nodded. The lump in her throat had returned, with company. Rarity's cunt seemed set to 'tingle' perpetually.
"Yes," she said, feeling her mouth go slightly dry. "I mean... Yes, my Princess."
Celestia's smile grew even wider, and her eyes glimmered with a motherly look of approval, again at odds with the leather and smell of sex permeating the room.
"Wonderful," Celestia said. "It seems you are a very quick learner. Twilight took several lessons before she remembered the proper form of address..."
Twilight shuddered against the riding crop as Celestia drew it between her legs again. Rarity caught herself licking her lips, wondering what the tassels at the end would feel like tracing over her clit.
"There is one last matter at hoof..."
"Mmm?" Rarity caught herself staring again, this time at Twilight, the way her body rocked back and forth, obviously pleasuring herself with little bursts of friction, but somehow hovering precariously right before the point of no return. It was hard not to imagine joining her, just starting her own rocking motion and grinding on her hoof or the stone until the two of them were locked together in whimpers as their bodies shuddered and seized.
To demonstrate, Celestia picked Twilight up, with magic alone, and spun her around until she was on all fours, butt stuck up in the air for Rarity to stare as much as she pleased. It took a moment to unglue her eyes from Twilight's well-cushioned lavender rump, but eventually Rarity took notice of her friend's tail—tucked in, between her legs and fastened there. Rarity felt like she'd seen the practice somewhere before, an illustration in a technical manual at school she'd buried somewhere in the back of her brain. It looked wrong, improper... hot for some reason. Rarity's cunt clenched as she squeezed her hind legs together again.
Celestia waited until Rarity had come back to focus, a sad and desperate look on her face.
Rarity simply nodded, her breathing shallow and sharp.
"Yes," she whispered, barely audible above Twilight's continual muffled moaning. "I want... please. I want... I want that."
"Very good," Princess Celestia said, her smile finally abating into a look of pure and focused discipline. She gestured with her riding crop for Rarity to turn around. "Assume the position."
Rarity did so. Just being turned like that when you knew somepony else was there and watching felt humiliating. You were completely exposed, they could see and touch anything they wanted. And, just like that, Rarity felt Celestia touching whatever she wanted, grabbing her tail, not hard, but forcefully enough to take notice, and then bending it under, Rarity's majestic purple curls being wound up until they were practically no bigger than a pig's tail. She felt that image in her head too, a little piggy on a farm, rolling around in the dirt... the words and descriptors all sort of blurred together in her head. Everything was hot and wavy.
"There," Celestia said, her voice coming through the haze and fog of arousal. "Now that you are in your proper attire, I would like you to attend to dear Twilight. Remove her blindfold and gag. Then the two of you are to exchange pleasures until I give you permission to stop." Celestia looked down at Rarity, making suddenly apparent the height difference between them. The steel in her eyes. "Understood?"
"Yes, Mis—I mean, yes, Princess Celestia." Rarity felt very small, meek, and horny.
"Good. You may continue."
It was easy enough to walk forward, though the sensation of her tail tucked and fastened did take some getting used to. Then there was taking in Twilight again, and she was certainly still there, mostly unable to move over the course of events. She was leaning towards Rarity as she approached, as though the tiny change in the tension of the air was enough to signal a sensation on her skin, the instructions she'd heard as well which Rarity came closer to enact.
"Twilight?" Rarity asked. Her voice felt shaky, uncertain. But Twilight seemed to hear her, and nodded, and a tiny pang of relief crept into Rarity's heart. Even out of practice, she could still follow directions like nopony's business. "I'm going to take your... take your blindfold off now, okay?"
Twilight nodded. Rarity could feel the heat of her friend's breath, slightly through the air, and it made her skin tingle and her coat stand on end.
Rarity took the blindfold off, and Twilight looked up at her, wide-eyed, for the first time since she'd entered the room.
Twilight's eyes told a story that needed no sound, and Rarity caught herself wincing and nodding in sympathy. Poor thing. However long she'd been tied up... it had been... difficult, that was certain.
"I'm going to take the gag off next, okay?"
Nod. Twilight looked closed to tears, and Rarity could tell it wasn't from any kind of pain.
When the gag came out, Twilight's breathing became more apparent, soft, shuddering gasps between her little whimpers, like the mewling of an adorable kitten. Rarity found herself full of a sort of sisterly compassion, wanting to reach out and bring Twilight close for an embrace, to hold her and reassure her with the closeness of her body...
Oh. But then, there was Celestia watching them, after all. Waiting for instructions to be followed.
"Is it... is it alright if I—"
Twilight had kissed her before she could finish her sentence. Rarity felt herself giving into the sensation, questioning it at first, then letting it take her over, her friend's hot, heavy mouth suddenly connected and sweltering and a dancing interplay between tongue and lips. Rarity caught herself rocking her hips forward, shaking in the air at an invisible, ethereal touch, already wondering what she'd gotten herself into by agreeing to Celestia's stipulation...
It was then easy enough that their hooves found each other—right next to each other, even in a stone dungeon, makeshift, of sorts, there was a lot of comfort that could be found simply in shared breaths and the closeness of forms. There was a carpet for them, at least, a red rug rimmed royal gold, and that was comfort enough when their attention was almost completely occupied otherwise.
Rarity felt like a nervous teenager in high school again. Somehow, despite all their closeness as friends in various adventures to save Equestria, the mane six had never fully devolved into late-night slumber party mares-only makeouts—though that wasn't exactly what Rarity had told Spike, on the occasions that he'd asked. You couldn't blame a girl for embellishing, especially when it garnered such an enthusiastic reaction...
"Oh," she caught herself saying out loud again, between kisses and chances to breathe. Twilight's hoof had touched between her legs, prodding gently to make purchase, and Rarity parted her legs almost instinctively to allow Twilight's hoof more room to explore. Immediately, Rarity's full wetness was realized to her, how her cunt had become completely soaked over such a short duration of watching, and now was at the mercy of Twilight's dedicated attention. How Twilight had managed to survive at Celestia's hooves was still a large component of the overall mystery. Rarity couldn't imagine herself holding out for much longer than a minute or two.
"Twilight, that's..."
Another kiss, too forceful to overcome, and Twilight was playing with Rarity's pussy in earnest, rubbing eagerly along the length of her slit, the soft, gentle slosh of filly-juices spreading the only sound in the room besides the still hurried and desperate breathing of the two occupants under direction, and their considerably more calm overseer.
Rarity had somehow assumed herself to be in charge, but now Twilight was practically shoving her onto the ground, face eagerly between Rarity's legs, as though she'd only been restraining herself due to the blindfold and gag, and was now finally free to ravish her friend as though she'd been dying to secretly for ages. Whether or not this was true, Rarity found the narrative sweeping into her head in bits and pieces, making every touch and tingle sizzle slightly more as Twilight's attentions continued. Rarity hadn't had her pussy eaten in the longest time, nopony seemed interested in it, and now Twilight was lapping at her like a pony in the desert dying of thirst. Rarity's clit had always been extra sensitive, and the second Twilight's tongue flicked across it, the howl that came from Rarity's throat was like a signal forward, ushering in more of the same, more eager licking, more of Twilight devouring Rarity's pussy like it was a study course of reading material. If Rarity's head had been spinning before, now it was a tornado, and each time she opened her eyes was just long enough to catch a flicker of the total image before it disappeared. Oh, she wasn't going to last long at all, she was going to get them both in trouble, Twilight, had to stop, please, Twilight, "Twilight, please—"
"Stop." It was Princess Celestia's voice. Like a piece of clockwork, Twilight's tongue froze. Then moved away with the rest of her.
Rarity couldn't help but let out a long, disappointed moan. She had been that close.
Probably why Celestia had stopped her in the first place, come to think of it.
"I believe I was very specific in my instructions," Princess Celestia said. "That you were not to allow yourself release until given permission."
Oh dear. Rarity could recognize that voice. It sounded a lot like the one she used when dealing with particularly troublesome orders at the boutique.
"Princess Celestia," she caught herself saying, the words springing from her chest before she'd taken the time to line them up properly. "If—I mean, I didn't, I certainly wasn't—"
"Silence."
Rarity shut her mouth. She wondered if it was as fun to say 'silence' as it sounded. Celestia let it drop like a badass.
"I would like the two of you to switch your attentions." Princess Celestia turned about as she spoke, until the royal posterior that had been the subject of so much speculation was on full presentation in front of Rarity's face. Sure enough, it was bigger than the average pony estimated and then some. Rarity caught herself staring wordlessly at the sheer size of her ruler's rump, wishing she could reach out and squeeze it just to test its softness.
"Oh," Rarity said, snapping to attention when she remembered what was at mistake. "Sorry, I was just..." Sunbutt. She shook her head, doing her best to clear the persistent thoughtworm. But there her Princess's booty remained, and so her eyes glued to it.
"Since you enjoy staring at my backside so much, perhaps you should start your duties there, hmm?" Celestia ran the tip of the riding crop under Rarity's chin, lifting it slightly, until the poor unicorn was staring up at the princess, her eyes quivering along with her trembling lip.
"Y-yes, Princess." Rarity gulped loudly, but spent no more time standing and stammering. She stepped forward as though she'd been given the key to heaven and began to kiss gently along Princess Celestia's butt. Little smooches at first, but more degenerate smacks as she got into it, finally evolving into the reckless motion of her tongue, licking anywhere she could find purchase to the soft, approving moans of Princess Celestia.
"Very good," Celestia said with a smirk. "Twilight, come closer. I have been wanting to taste you for some time today."
"Yes, Princess," Twilight said, subdued and obedient. She came to her princess at once, spread her legs until her dripping slit was on display, and Celestia leaned down to press her tongue against it, causing Twilight's whole body to shudder and her voice to squeeze out of her chest in a desperate, squeaky sounding moan.
"Mmm," Celestia said, licking her lips, already slick with Twilight's love-juice. "My faithful student is as sweet as ever."
"Th-thank you, P-princess..." Twilight's ability to compose herself seem to have vanished completely in an instant, the facade of her willpower crumbling the instant her teacher's tongue came into play.
Where the room had been mostly silent and hurried breathing before, now the sounds of sex were in full swing: Rarity doing her best to pleasure Princess Celestia's posterior while taking occasional care to attend to her royal cunt as well, Twilight spread out and on display, incapable of hiding any longer from her approaching orgasm. Celestia's over-sized rump waggling back and forth in her new servant's face, taking the riding crop and using it to guide Rarity's hooves, to attend to all parts of her princess, and not leave an inch untouched by tongue and hoof.
Rarity wished she could put quite properly into words the sensation of debasement—the way she felt cheap, and slutty, but at the same time proper and demure... it was a little play session for all of them, rules in place just then, all that would slip away when finally the cleaning was done... Rarity couldn't help herself much longer, that was certain, she was going to explode like a geyser, could tell from just how pent up she'd been and how extra real it all felt—yes, it was certain, she was that close, was going to break and crumble and fall apart just any moment now—
"Princess," Twilight cried out, between her moans and panting. "Princess, I can't... can't hold—"
"Mmm... you may cum, my little pony. Wrap your legs around your Princess's head as you do."
Twilight had just enough time to process the instructions and begin to follow them as her orgasm hit. It was like a house leveling, or an earthquake. Her body shook, and her breathing seemed to stop, held up in her chest as her entire frame shuddered and shook, Celestia's tongue flashing fervently up and down on her slit.
"Oh my," Rarity said, swept up in the same overflow torrent as her friend. Princess Celestia had barely touched her, was barely paying her any attention, and yet here it came regardless. "I think I'm—that is, Princess, may I—"
Princess Celestia ground the riding crop hard between Rarity's legs, and that was enough of a permission slip for her. Rarity came just as hard as Twilight, if that was possible, shuddering and dripping filly-juice onto the stone floor, and soaking the rug besides.
And Princess Celestia, at last, as though she'd been waiting for both of her students to finish first, allowed herself an all-encompassing, earth-shaking, body-shuddering orgasm. Her rump jiggled and trembled as her body rocked up and down, her legs clenched tight, only a little trickle of juice from her cunt dripping down onto Rarity's mouth, wide with her own orgasm. A symphony of all three of their sounds at once, with Celestia's moan the loudest, a lioness roar atop the peak of three.
When everypony had finished, the room had more or less the vibe of a nuclear detonation's aftermath. While everything that was there at the start still remained in place, everypony was much sweatier, stickier, and full of good feelings—the kind of impossible to grasp, entire consciousness falling away part of the aftermath that lingers until somepony finally decides to move.
It took a while for that part. Twilight and Rarity both curled against Celestia's body, all three of them taking space on the rug, like a mother cat and her kittens nestled together. Rarity found herself cherishing especially the sensation of her tail still tucked, as though its firm fit between her legs was simply a sign that it had fallen into the right place.
"Well," Rarity said with a sigh, the smell of sex permeating the air. "I guess that solves one mystery for now..."
