The Two Between

“Princess, I’ll be heading out as usual!” Sunset Shimmer’s cheery voice sang through the library just as Twilight finished her daily to-do list (it really irked her to no end that she couldn’t ever put making the checklist as an item on the checklist). “I’m going out to pick up some new quills and some extra parchment before heading to Rarity’s. Is there anything you need me to do while I’m out?”

“I can’t think of anything off the top of my head,” Twilight half-shouted down the stairs, distracted as she began sorting through the fiction and non-fiction books to be replaced on their shelves. “I’ll send Spike out if I need anything while you’re gone. Say hi to Rarity for me.”

“I always do!” Sunset replied and the snap of a closing door signaled her departure.

It had been two weeks since Sunset Shimmer’s outburst, and Twilight wasn’t entirely positive if she ought to be incredibly proud of Sunset Shimmer, or incredibly suspicious. On the one hoof, she had quickly adjusted to life in Ponyville and immediately made herself useful around the library. In fact, Twilight had been getting her tasks in the library done at an unheard of speed, leaving both she and Sunset plenty of time for other activities.

On the other hoof, those activities that Sunset had been getting up to were suspicious in the extreme. Why in the name of Celestia’s mane did she feel the need to sneak in and out of the library at odd hours? What were the oddly shaped packages she was bringing back from her errands, and what did they contain? And most strangely of all, what on earth had those strange and at times frightening noises coming out of Sunset’s room been?

She’d insisted nothing out of hoof was going on, assuring Twilight that she had just been pushing her physical and magical limits through exercise now that she was a pony again. But Twilight was well and truly wondering. Princess Celestia had once assigned her a book on the ethical considerations of magically experimenting on other living things, and the pages had taken the time to detail the noises when an experiment was going horribly wrong. And while Twilight couldn’t exactly translate text into sound, the words were apt descriptions of some of the noises she had heard from Sunset’s room.

Still, she’d had more than enough painful experience at making presumptions at this point to know that she couldn’t decide anything without proof. For a full minute, she fretted with the parchment roll in her hooves trying to decide what to do before coming to the conclusion that she needed more data. “Spike! You’re in charge until I get back, I need to go see…” She hesitated. Who on earth could she claim to be visiting that wouldn’t arouse suspicion? “... Miss Cheerilee about that magic demonstration!” That was a boldfaced fabrication, but she was certain Spike would buy it.

Sure enough, “Okie dokey, Twilight! Just leave the morning set up to me.”

Spike’s solid reliability was always a relief in times of stress, and today was no less so. She paused only to grab a small saddlebag from the side door before slipping out into the Ponyville morning. She’d need to find Sunset’s path in a hurry, so she quickly flared her wings out and took awkwardly to the skies. Though her flying had notably improved as of late, she was certain it would be a very long time before she could do it as easily as other pegasi. Still, as she rose above the streets of Ponyville, she couldn’t help but feel a rush of pleasure at the once impossible activity.

Spotting Sunset was surprisingly easy, her mane sticking out even in the colorful populace of Ponyville. She appeared to be heading off to the market square, and Twilight set a relatively simple glidepath that would allow her to keep an eye on her without having to do too much wing flapping. Of course, she failed to account for the sudden appearance of that wild blueberry bush that she crashed into mere moments later, but blessedly no one in town seemed to notice her crashes any longer… and besides, it was an excellent hiding place to observe Sunset.

She was standing at one of the tradespony’s stalls, apparently looking at something in a mysterious wooden box. The pony who was in charge of the stall looked incredibly shifty, with a strange looking fez and glasses, and a well tailored if slightly ratty vest. She narrowed her eyes and carefully summoned up a Listen-In spell to try to find out what she might be purchasing…

“So, its the real deal then?” Sunset’s voice echoed strangely in Twilight’s ear. The distortion was mild, but consistent, and Twilight wondered if perhaps the shifty trader had objects to thwart weaker versions of her spell.

“Of course!” The trader’s voice was unctuous, if a bit warbly. “Only the very best craftsponyship. We guarantee the product is…” His voice cut out a moment later as a pair of burly earth ponies cut between her and the stall, yammering on about sweet potatoes before the trader’s voice cut back in. “... Only the finest specimens, even with the Princess’ restriction on the trade of such substances.”

Twilight almost let out an audible grumble as a partitcularly boisterous clout of fillies burst into laughter and blocked Sunset’s initial response. “... got to have enough juice. She’s not an amateur, so it’s gotta be able to pack that extra punch.”

Twilight felt a little confused at those words, and it only got worse when the trader spoke in an enthusiastic tone of voice. “We guarantee it can handle even the strongest unicorn magic, though of course we recommend…” As if the world was conspiring against her, the Cutie Mark Crusaders picked that moment to go rocketing past on Scootaloo’s scooter, cheering the little pegasus filly on to faster speeds. “... And just to seal in the deal, I’ll throw in this special little potion, provided by our very own local Zebrican shaman. Guaranteed to provide the very best results.” He winked, slyly. “If you know what I mean.”

“If I’m paying that much, it had better vibrate when…” Sunset was bargaining before the spell’s duration winked out completely. Twilight considered recasting it immediately, but before she could even summon the magic, Sunset’s bits were on the counter and the exchange was over even faster.

Sunset was turning away into the crowd,and Twilight nearly screamed in frustration, but bit it back just in time to spot a familiar pegasus duo trotting through the crowd toward Sunset. She quickly glanced left and right before dashing out toward an empty stall, quickly setting up behind it and peeking her head above the counter in time to see Sunset giving Rainbow Dash and Fluttershy both enthusiastic hugs. With another mutter of concentration, she rebuilt the Listen-In spell with a great deal more power, resolving to rebuild the whole bucking spell from scratch when she got back home.

“I didn’t think I’d see you two today,” Sunset was saying to Rainbow and Fluttershy. “I thought you two were hanging at Dash’s place for the day.” Twilight hated to infer tone and mood when she used this particular spell, since the echo changed things, but she could have sworn Sunset sounded nervous upon encountering Flutters and Rainbow.

“Nah, we were,” Rainbow’s carefree voice snatched Twilight’s attention. “But ‘shy here just wasn’t diggin’ - “ The spell cut abruptly, leaving Twilight with a tinny sound in her ear and a minor ache from magical backlash. Damnit! Stupid unicorn, casting too fast always leads to bad results! She would need to wait for the noise in her ear to abate before she could recast, so she was stuck with just seeing physical gestures…

And quite abruptly, Rainbow Dash’s forehoof came around in a swift arc and smacked Fluttershy very firmly in the flank, just above her cutie mark. Fluttershy let off a bright squeaking sound and nearly jumped into the air before settling down, her cheeks blushing brightly and giving Rainbow Dash a slightly embarrassed look. Twilight had to admit, there weren’t many things in the world that could utterly baffle her… but what had just happened definitely qualified. It was so completely perplexing that she nearly forgot what she was supposed to be doing until Sunset twitched her hips back and forth, almost sashaying in place with a coy smile on her face. The tinny sound in her ear vanished a moment later, and she quickly but much more carefully rebuilt the spell, hoping she could pick up on what had just happened.

“... wish she would hit me like that,” Sunset was just finishing. Now Twilight was far from perplexed; she was outright bewildered. Of all ponies, Sunset was the last she would choose to seek out defeat or anything similar. Rainbow Dash opened her mouth, and Twilight let out a little gasp before ducking down behind the stall, realizing belatedly she had stood up without even realizing it.

“It’s okay Shimmy,” Rainbow said, almost consolingly Twilight would say. “You’ll just have to get her used to it is all.”

“And you are very pretty,” Fluttershy added, her blush intensifying.

“Yeah, give it a bit, Rarity knows how best to deal - “ Dash was replying, but now the three of them were walking away, and the spell lost its power. Twilight considered backing out now, but… worst come to worst, she could just waltz into Rarity’s place if the conversation took a less than savory turn, but only if she stuck with them. So she trotted along in their wake, carefully remaining out of sight and hoping that the situation didn’t get any stranger than it already was.

Travel to the Boutique was relatively fast, and the trio of ponies ahead of her were enjoying a raucous conversation which Twilight could not hear much of beyond the giggling. Even Fluttershy, of all ponies, was getting in on the fun with a bright smile of her own. Though she was sticking almost suspiciously close to Rainbow Dash… Odd. At any rate, their approach to the Boutique was greeted by a cheerful Rarity, a measuring tape draped over her neck, and her glasses perched upon her nose. “Darlings! I didn’t know you’d be joining us today…” There was a sultry undertone to Rarity’s voice that Twilight was unable to immediately categorize, even though it was tickling at the back of her mind.

“Well, we never really got started this morning, so we hopped down to the market, and ran into Shims,” Rainbow explained. “Ya don’ mind do ya?”

“Oh, of course not dear. These things are always more exciting with more ponies, as I’m sure you know,” Rarity replied, motioning for all of them to come inside. She shared a knowing smile with Sunset, and Twilight began to see signs of something sinister. That smile, that smile Rarity had given Sunset was different, meant specially for her. And as far as Twilight knew, only secret groups and enemies of Harmony used such subtle code. What exactly had Sunset dragged her friends into? Or worse, what had her friends been involved in and dragged poor Sunset into? Either way, if she was going to alert Princess Celestia, she needed details on this… secret club the four of them seemed to have formed.

That meant she only had one recourse, distasteful as it was. The door the boutique had been firmly shut, and the drapes drawn a moment later. Barging in wasn’t a smart move if somehow Sunset had coerced her friends into some kind of strange ritual. She needed more data. Data, data, data… she could not make bricks without clay! So… go to the source, then. Surely Sunset had left some sort of clues in her room. She turned on her hooves and quickly galloped back toward the library, hoping she could figure out what was going on… before it was too late.

~~~~~~~

Spike was sound asleep in his little bed, tucked in and oblivious to the world and for once, Twilight was thankful for that. She stopped at the threshold of Sunset’s room in the library, and nearly danced in place as she wrestled with the inappropriateness of just… searching her room without talking to her first. But there could be no time! You can apologize later if you’re wrong, Twilight! That was enough of a thought to send her careening into….

A perfectly ordinary looking bedroom. No demonic symbols on the walls, no signs of black magic, no evilly bubbling cauldrons. Just a neat, tidy room. Twilight eyeballed the place, hitting all four walls and the floor with blasts of illusion dispelling magic and found that they remained stubbornly mundane. Her first fears quelled, she went to work carefully combing the room for her intended target, and found it almost instantly: tucked under Sunset’s pillow. It was obviously a custom made piece of work, and probably a good ten or fifteen years old given the state of the binding and the slightly faded colors.

With a deep breath she cracked it open and started leafing through it as she continued to run her magic over the many corners of the room, searching for secrets. The entries started out innocuous enough, often times just ending up being places where Sunset had vented her anger at something or somepony. Harmless really. Well, except for the parts where she called Celestia an ‘Old Fool’. And judging by the neat, ordered size of each entry, Twilight realized she was unlikely to find anything useful in the little book.

But of course, that still left the more obvious hiding spots: the ones that needed only the magic of a thorough hoof and sharp eye. Twilight lifted away the bed skirt to Sunset’s frame, and sure enough, there was a decent assortment of variously sized chests. It might explain the lack of black magic and cryptic runes if she kept them sealed away in magic crates. Clever really, when Twilight thought about it.

Preparing for the worst, Twilight erected several magic barriers covering a wide range of spells and curses and their effects. The chest wasn’t locked, only deepening Twilight’s apprehension, but confident in her protection, she threw it open to reveal… “Wait, what in Tartarus?” Twilight asked herself aloud. She plopped into sitting just as she levitated a small metal pole from inside the chest. It was a touch smaller than her shower curtain rod and was about the same width. Though neither of these things explained why Sunset even had home repair items stowed away beneath her bed.

Twilight felt her brow becoming almost permanently creased in confusion as she dragged out more crates. The next was filled with nothing but miscellaneous junk as far as Twilight could tell, albeit well cared for junk, but still junk. There multiple strips of fabric in a variety of colors, but they weren’t really big enough for anything except maybe a headband. Twilight tossed aside three pairs of old hoofcuffs from one, along with one and a half pairs of ping-pong paddles. Two of the larger crates were filled with nothing but rope of varying coarseness. There was also the most ridiculous looking leg band she had ever seen thrown in the mix: a big, obtrusive red ball with far too many extra fastenings and straps on it and a very elaborate looking bridle attached to it.

When there was but one chest left, Twilight took a moment to stare around at the mess of random items strewn about her. She dug deep into her reserves of logic and analysis and… nothing. She could find nothing that connected any of the things Sunset had for some mysterious reason been stockpiling. But she still had the last chest, and science had proved to her time and again that one left no box unopened. Except this time, she wish she hadn’t listened to science.

She felt almost dirty just looking at it. There was a copious amount lingerie inside the final crate, and it was of the more erotic kind Twilight was for sure. She levitated garment after garment from within, and while each pattern and color differed slightly, Twilight couldn’t mistake the refinement of Rarity’s work anywhere. Well, it at least explained why she went to the Boutique so often. Only, when Twilight reached the bottom, she discovered not just undergarments, but a full outfit clearly of a sexually provocative nature. It was again, clearly of Rarity’s design. And to layer on this confirmation, a small scrap of paper rested on the outfit, and with words written in pristine letters only formable by magic, it said, “For the first time.”

Now Twilight’s mind absolutely refused to try to piece it all together. Random bits of home repair junk, bootleg jewelry, and Rarity’s more specialized line? It made no sense, none at all. Except, she hadn’t read through the journal, front to back. In a frenzy, Twilight stowed all of the items back in their chests, haphazardly sliding them back under the bed and nearly leaping for the journal before pulling it open.

This time, she quickly repaired her earlier error by flipping through the older pages until the obvious break in the timeline. It didn’t take long to find the abrupt change of tone, followed by an almost subtle change in hornwriting style. The last pages before Sunset’s self imposed exile had become bold and obviously frustrated, giving way to much more delicate letters forming precise lists. Page after page of them, with no end of footnotes and pages clearly marked for later reference. In between the lists, the pages gave way to more informal writing…

I actually thought clopping off to her kissing me would get rid of the fantasies. It always did when I had the same problem in the other world. But I’m still stuck with the ideas. I’ve got so many things I want her to do to me, and I’m so tired I don’t think I’ll remember half of them in the morning. Oh… maybe I will anyway. I should write it down at least. What I can remember. I’ve got no doubt it’ll make the next time even better, not having to start from scratch.

Twilight stared at the passage for a moment, which quickly gave way to an entirely new set of lists… this one of very, very explicit words that described acts she had no reference for. Even moreso, a single name stood at the top of the list in an almost lovingly flowing script: ‘Princess Twilight’. Beneath it, a series of short paragraphs, each describing a confusing number of acts. Everything from Sunset being ordered into a fancy maid’s outfit and made to clean the library to… Her cheeks suddenly inflamed, as the explicit and frank wording of the paragraph was all too clear about what it thought Twilight would make Sunset do. But the confusing and baffling question remained, where did all of this come from!?

She delved further into the book, now driven by her relentless curiosity more than anything else...

Tonight’s been a seesaw for me. First I practically dump out my feelings to Princess Twilight, then run off to Rarity. And she was amazing! She knew how to listen, when to talk, and when to tell me what to do! And she gave me an outfit like I’ve been dying to have for so long. She even included a collar! Better yet, she invited me to come back. I think she knows what I’ve been searching for all this time, and gave me the titles of books to look for. There are several already in the library just at a glance, and I’m sure I’ll find more if I search harder.

That startled Twilight immensely. Wait, I have BOOKS about these things!? Why didn’t I… She shook the thought out quickly, turning through the pages and noting the titles. Some of them were innocuous, but others… why hadn’t she ever investigated such strange works? Had she really been that busy with other things? She was almost entranced now as she turned to the next entry in the journal, wondering if she was tumbling down a rabbit hole she wasn’t prepared for.

Things are going really well since I’ve been in Ponyville. Princess Twilight is an amazing teacher, and maybe she’ll eventually be my mistress too. The books have told me so much, and reading multiple ones, I’m finding which things are constant: the stuff a good submissive is supposed to do and how one should properly act. Rarity is still being a huge help, always giving me the sexiest clothes. And I couldn’t believe it, but she told me I should talk to Fluttershy and Rainbow Dash too, though she wouldn’t tell me why. Oh! And one of the best books I’ve read not only tells me the kinds of things to use, but where to get them without anypony really noticing. I have to go get at least some stuff before the week ends. I think rope would be good. Then my mistress could tie me up if I’m ever a bad little filly!

Some strange feeling was working its way into the core of Twilight’s mind as the words floated off the page, her tongue darting out to moisten dry lips. It was like the first time she’d ever heard of the subject of sex, ironically from a stolen glance into Cadence’s own journal. Like she was looking through a peephole into a set of ideas and thoughts that she was only dimly beginning to understand… and some kind of deep and primal desire to know a great deal more as quickly as she could manage. The next entry was the last one, written last night she was certain, and what it contained…

”Get on your stomach servant,” Princess Twilight commands me. “Now, you know what I need. Lick me clean, and I mean it. If you don’t go deep enough, you’ll have to do it again until I -”

WHAM!

Twilight backed herself away from the journal, now sitting oh-so-innocently upon the sheets as her breaths came in heavy and unpredictable gulps. In all of her academic life, rarely had she felt like she was teetering on the edge of something so deep and unknown like she did right now. It was like looking down into a black abyss, uncertain of what might lie at the bottom and yet fascinated just the same at the possibilities. And much to her embarrassment, she felt a faint pulse of desire echo out of her core.

She had but one recourse now. Celestia had to be informed, but if Twilight did not know what she was talking about, the message could become hopelessly muddled in terms she did not understand. That meant she had to become educated in this subject as quickly and thoroughly as time could manage. She carefully, reluctantly, tucked the journal back under the pillow and quickly escaped the room, the names of the books Rarity had referenced to Sunset burned into her mind. This was her library, damnit. She was not about to be out-done on her own home turf.

Fortunately, Spike was still sleeping like a log. Good. She didn’t want him involved in this. She put on her best determined expression and went looking for the books and whatever else might be lurking on her shelves.

~~~~~

Sunset Shimmer had never been known as a happy filly. Her parents even told her so. She had never skipped, had rarely smiled in public, and had kept her conversations completely factual and informative. But now, now everything could not be more different. As if a lively tune were playing from instruments only she could hear, Sunset all but danced through the streets of Ponyville, a triplicate of parcels swaying with her in her magical hold. She smiled warmly and excitedly at the average passerby and greeted the few ponies with whom she was becoming familiar with a wave and friendly greeting.

She had every reason to be so upbeat. For the first time in her life, she had friends she felt she could talk to about nearly everything, and who often seemed to understand her better than she even understood herself. Rarity was still being as helpful as ever, seemingly imagining every possible scenario in which Sunset could confess the details of how she felt. She was also perpetually generous in giving Sunset exquisite lingerie, and Sunset was sure that within a few more trips she could confidently boast the largest collection of suggestive clothing for several miles. Thus far, Sunset quite liked Rarity’s idea to attend some event where dresses would be common and ‘accidentally’ bend down and allow Princess Twilight to see her evocative undergarments.

And while Rarity’s advice and suggestions were supremely helpful, Sunset very much enjoyed simply talking about the subject of doms and subbies with Rainbow and Fluttershy. The two hadn’t said anything outright, but they knew far too much about such a relationship to not be in one themselves. But vague insinuations aside, they both gave Sunset a glimpse of BDSM that Rarity simply could not. They made it sound fun. And to top it all off, today Rainbow and Flutters had each given her a special present. Dash had insisted she wait to open hers, but Fluttershy had given her another ball gag. Only, according to her, it was special: imbued with magic, it vibrated and grew into a rather special shape when the command was given. Oh! She couldn’t wait to have Princess Twilight force it in her mouth!

The door to the library swung open to reveal a sight Sunset had never before seen until today. The library was… disorganized. And not in the usual mess the place was in after a busy day, but in that unique sort of way that suggested vigorous and frantic research. Books were piled on every available horizontal surface, and little piles of scrolls dotted the landscape like mountains of parchment. Sunset felt her jaw hang slightly open at the sight of so much chaos, wondering what could possibly have seized Princess Twilight’s attention so thoroughly that she had left the place in such a state.

She carefully closed the door to the library behind her and threw the bolt on the door. A touch of magic turned the sign indicating the library’s status as open to closed, and she carefully tucked her packages into her saddlebags by the door, along with her purchases for the day. “Princess? Is something the matter?” she ventured into the silence but received no response. The entire library was eerily still at first, until…

scratch scratch... came the sound of quill against parchment, and Princess Twilight’s unmistakable voice muttering from her rooms. Sunset picked her way up the steps, doing her best to remain perfectly silent until she could determine what the source of the chaos was. It didn’t take her very long to reach the door and press her ear carefully to the wood. It took only the barest touch of magic to cast her listening spell on the door, and then… Princess Twilgiht’s voice came through loud and clear.

Scratch Scratch… “Books note that pleasure can be a function of pain. Results substantiated due to release of endorphins by the body that can be manipulated through careful application of pain upon a submissive using specific tools designed to trick body into releasing more than is necessary.” scratch scratch scratch… “Book also specifies that bodily restriction can create an odd psychological effect, in which the submissive feels more ‘free’ due to trust in the control of the dominant.” A pause. “Corroboration may be difficult, but makes sense in context. Knowing somepony is in total control of the situation can create feeling of freedom, allowing somepony to let go otherwise hidden fears or desires...” A cough. “At least from personal experience.” Scratch Scratch...

No. That was literally all Sunset could think at first. It wasn’t panic, or fear, or anything else. Just blank denial of what she was hearing. Of course, being in blank denial only lasted for a few seconds, and Sunset felt the tightness in her chest again as she was struck by the tidal wave of emotions. Princess Twilight was reading the exact same books she had, which could only mean she suspected something. Had she gone through the things she’d bought and that Rarity had given her? What did she think of her now? It couldn’t be good. Princess Twilight would probably only be able to see her as a pervert or worse…

There was a sound of Princess Twilight stretching and a deep, exhaled breath, ”Side note: Mmf.” Another stretching sound, and the creak of a wooden chair. ”There is a certain allure in the highly regimented nature of these practices. It’s kind of strange, romance always seemed like such a messy concept when Cadence described it. But this is something that makes a great deal of logical sense… a clear delineation of power between two individuals, an understanding of responsibilities on each pony’s part. No misunderstandings, provided both ponies can easily communicate.” A distinct pause, and the sound of a glass returning to a wooden desk. ”I’ve got to admit, I can even see how something like this would help Sunset become a better pony. A very clear set of rules with corresponding rewards and punishments. That those punishments can also be pleasurable, and the rewards…” Twilight’s voice trailed off then, followed by a rustling sound.

Under normal circumstances, Sunset wouldn’t have taken any heed to such a small sound. But her step-oriented, logical mind had already been overwhelmed, and it took no small amount of imagination for her to put together an image of Princess Twilight in her room, legs wide and pleasuring herself with Sunset’s own name moaning out her lips. Her horn seemed to be working on its own as well, levitating her new vibratory gem into her waiting hooves.

Not bothering with trying to find a softer surface, she leaned onto her back and levitated the gem toward her nethers, gently teasing her nub with its cool, smooth surface. She hadn’t waited the last time to feel her lips beginning to drip, but as she fondled her clit with the gem, waiting for Princess Twilight merely to move again, she became quite aroused upon feeling the moistness.

Princess Twilight’s voice came again, slightly huskier than before. ”Collating techniques has been frustrating. Every book seems to have it’s own idea of how a given technique is supposed to be used. Example: four separate books provided contradictory instructions on the use of…” A pause, a ruffling of papers. ”a vibrator in the pursuance of orgasm denial. The best of these books seems to recommend using knowledge of body language to make sure a submissive is nearly at peak before using pain to counteract the pleasure, then repeating this process until the desired outcome. The other three books provide much different instructions, leaving me to pick up the academic pieces.”

Princess Twilight… vibrators… “Mmngh!” Sunset strangled her cry of jubilation as she channeled her magic into the gem for its primary function and began rubbing it against her folds. Princess Twilight was keeping it from her. She wanted it so badly, but her princess had been very clear, it was she who decided when her little Sunset could cum. So, as the shaking gem rounded her now dripping slit, Sunset tried to not moan too loud, her head shifting from side to side and her back arching in eager desire.

More sounds of parchment scratching, then a sudden slamming of a book closed. ”No discernable patterns at all in technique! Ugh!” A grumbling sound, almost angry words coming out. ”Simmer down, Twilight. The last few books at the very least have an almost absurd level of detail when it comes to describing more advanced techniques, most of which revolve around either bondage or the psychology of what the books call ‘play’” A gentle rustling, a shifting of weight in the chair. ”It’s almost fascinating how they provide instructions to take an otherwise ordinary but submissively inclined pony and reshape their behavior to the whims of the dominant without coming across as evil or malicious. Such instructions include demeaning or degrading costume, enforced restrictions on what a submissive can and can’t do, and treating the pony as a lesser creature than yourself.”

Sunset couldn’t take her self-inflicted teasing any longer, inserting the entire gem into her sopping hole. The sudden burst of pleasure from the act sent a magnified charge of magic into the gem, giving her a brief increase in the roiling sensations of sex. Princess Twilight would soon thrust the gem into her, all the while nibbling at her love button. Sunset’s hooves found their way to her inner thighs, stroking provocatively and eliciting a shudder of anticipation for all the trouble she would be in should Princess Twilight catch her.

There was a distinct pause in Twilight’s musings that lasted almost a beat too long, before her voice streamed through the door again. ”Initial conclusions suggest that this subculture is-” Pause. “Yeah, it’s got to be categorized as that, silly as that sounds. This subculture is clearly, surprisingly not as malicious as I had originally thought. Much of this is based in scientific fact about how the pony body works, and is simply exploiting it through rigorous application of that knowledge.” A gentle sigh and a deep breath. ”And if I’m going to be honest with myself, which Celestia would want, I can’t help but imagine what it might be like to use some of these techniques on somepony like Sunset. It’s an… intriguing prospect.” There was another rustling sound, and Sunset could have sworn she’d heard a soft moan...

She… she wanted to play with Sunset, of her own accord? The shock of such a development almost knocked away her lust, but it came back fiercer than ever. Princess Twilight will tie me up, show me what happens when dirty fillies play too much! Her magic grasped the vibrating gem. Its rate increased, and she stopped even trying to hide the moans as her eyes shut to the sight of Princess Twilight ordering her to lubricate her horn. She was moving the gem in and out, in and out, leaving it to linger and rub harder against one side of her walls. A shivering warmth was spreading through her body, and Princess Twilight was becoming more and more pleased with the wet state of her - !

The bottom, or rather the door, suddenly dropped out from behind Sunset’s back, sending her falling straight to the floor of Princess Twilight’s room. And she found herself staring straight up between the Princess’ forelegs with her eyes staring in wide shock down at Sunset. For a few long moments, only the sounds of the buzzing jewel and her own uncontrollable panting moans filled the air. The world ran thick with tension as something inexplicable built up in Sunset’s chest like a dam threatening to burst…

And then it did, sending her body into a single convulsion of pure bliss at the impossibility of the scene she found herself in. The world went white all around her for a few glorious seconds, and when reality returned she found herself still staring up at Princess Twilight… who had gone from shock to an almost speculative look on her face, her cheeks flushed a bright red and her hoof tapping in what had to be an unconscious motion. And just because the situation wasn’t crazy enough, the princess had to go and open her mouth.

“Sunset, I think we need to talk,” she said quietly, obviously trying to deal with the almost absurd situation calmly.

“I know we need to talk. I… I want to talk,” Sunset replied, debating on whether or not to pull the gem from her nethers, as the waves of pleasure were slowly dying away and it was no longer vibrating. “Is that… May we, Princess?”

Princess Twilight took in a deep breath, lifting her hoof to her chest before blowing out the breath with a slow motion away from it. Her cheeks were still almost flaming red when she spoke again, but she was keeping her cool remarkably well, “Come inside, and we’ll talk.” She paused, and her blush got worse as some thought crossed her mind. “Um… That is to say… Oh, ponyfeathers, just get in here!”

“Yes, Mistress!” Sunset answered reactively, just as Rarity had shown her.
