Twilight, Rainbow, Rarity, and Applejack just wanted a day with their coltfriends. The Cutie Mark Crusaders just wanted help with their assignment. Twilight, always the flexible pony, has come up with a compromise - whether the CMC realize it or not.

Secrets are, admittedly, hard to keep - almost as hard to keep as a library. Spike knows about one of those things; but Twilight is more than acquainted with both. She's also acquainted with the vast and varied uses of the many applications of magic. What happens when her magical might and the - admittedly sexy - secret she and her friends keep meet with circumstance produced by three fillies with an assignment due the next day. The answer? A lesson in more than just what the teacher intended.

Cleaning and Clearing the House

"Thank you for visiting today! Please come back tomorrow if you have the time!" Twilight called out behind the last pony as they walked away. It was in different ways both the best and worst part of the day - the closing of the public area of the Golden Oaks Library. A day of hard work now drawing to a close meant only one thing for the two residents of the library: time to relax.

"I can't believe how much of a mess some ponies leave behind." Spike complained as he gathered up the books for reshelving. It would eventually mean time to relax, of course, but library maintenance always took priority. One couldn't just leave the library in a state of disarray because they were tired. It was their solemn duty to keep the place in good order. Fortunately, Twilight - with the power of an alicorn overly familiar with her library - made quick work of placing books back where they ought to go until the next reshelving day.

"Another day drawn to a close. Feels good, doesn't it, Spike?" Twilight asked with a sigh, absentmindedly hefting her prodigious bust with her arms as she crossed them in satisfaction. Spike, the true brother that he was, was the last to notice this. Unfortunately with only the two of them in the room at the time he was also the first. He turned away, not wanting to look at Twilight in that way.

"Yeah, I guess. Let me get the broom and dustpan and we can get this place spick and or span." He said, distracting his thoughts with images of Rarity instead. It was alright to be horny or to fantasize so long as it wasn't about Twilight. Anypony but Twilight.

"Thank you, Spike! I'll check over the shelves and make sure we have everything in its place." Twilight called as he rushed to the broom closet. Had it been anypony else giving that offer, the balance of effort would've been weighed in the book checker's favor, but seeing as it was Twilight saying it, Spike was likely to find himself lagging behind.

Twilight hummed a jaunty tune to herself as her magic scanned over the books, moving the ones that had been put in the wrong place - whether by intention or not. It was trivial work for the alicorn, almost relaxing in its own way if not for the minor amount of effort it called for. Of course, her preferred method of relaxation - a type she'd indulge in later tonight - demanded far more effort than even this, but its rewards were... different.

Spike, on the other hand, was looking forward to a night much like any other night. He had a new comic to read and it was just getting good. He just couldn't wait to be done with his chores so that he could read the continued adventure of 'Mare Mysterious and The Case of the Golden Ghost.' The previous issue 'The Case of the Flagrant Felon' was one of his favorites, and he couldn't wait to see how the newest story unfolded.

The work to straighten up the library wasn't too great, and better yet, didn't take too long. After a short bit of effort, the place was back to its regular set up for tomorrow - depending, of course, on whether or not they were still here or out fighting evil or something of that nature. It was good to see the place looking so neat, even to Spike who was more or less ambivalent to the whole thing.

Twilight smiled to herself, humming as she set up a few things here and there as Spike pulled out his comic book and fell into his favorite beanbag with a sigh. Whatever Twilight was doing was beyond his realm of caring, which was good for Twilight. Spike cared more for his book than whatever extra work Twilight had set up for herself. If she wanted to work more than necessary, he was fine with it - so long as he wasn't roped into it. Surprisingly to the young drake, she hadn't tried to rope him in this time - a welcome change to be sure.

Turning page after page, engrossed in his reading, Spike barely noticed the arrival of Applejack, who greeted Twilight warmly. Twilight having a guest wasn't too incredibly odd - especially with it being one of the Elements. Spike continued his reading happily, pulled deeper into his story as Mare Mysterious slowly found her way from clue to clue. Spike had a reasonable suspicion of both the livery maid and the mail boy - but the problem was whether those were the reasonable suspects that were misdirects or not.

The opening of the door to let in Rainbow, huffing and puffing from her workout wasn't odd to Spike when it happened a few minutes later. Friends did stuff together. He'd have been out and about doing things himself had it not been for the rough day he had just endured and the general lack of anything to do besides reading his comic. Not that he wouldn't have done something else if it presented itself, but Mare Mysterious wasn't to be denied without good reason.

Unlike the last two arrivals, Spike did notice quite acutely as Rarity entered. Almost a shame that it happened as the mail boy was found dead in the back of the haunted mansion - supposedly haunted at least. Rarity's radiant and undeniable beauty was enough to pry him slightly away, losing the question of if it had been a faked death or not he would have had otherwise. Mare Mysterious was great, but Rarity - the Mare Marvelous - was far more eye catching to Spike.

Her choice of clothes didn't help this. She wore what would likely be considered a modest dress that most ponies wouldn't have problem with. It was made intentionally that way. The problem was that it got close enough to immodesty and then skirted the edge with the use of frills, lace, and tactical folds of the fine cloth that made it up. To the dragon who had spent enough time with the fashionista to learn her wily ways of dressmaking, the ever so subtle lines that drew the eye to just the right places were obvious and undeniable - though Rarity doubtlessly would've denied such when asked. It was a perfectly modest get up with no true faults - except those that were baked into the very DNA of the dress.

This caused a brief glance to the ignored mares in the library. Rainbow wore her usual sports gear, though his learned skills in dressmaking provided the information that her sports bra was cut ever so slightly lower than most and propped her chest up that much more - likely through the use of padding or just excessive support. Her shorts were also shorter by a hair - an important hair. With the angle he had, Spike had a great view of that pegasus' tight ass that received such flattering treatment by the tighter shorts.

Applejack wore her usual pair of beaten jeans and plaid shirt with cowpony hat, but event this was altered slightly. Her shirt was tied up just beneath her bust, revealing all her midriff. This alone was not suspicious or odd, as she had done it in the past when the going got especially dirty - but when compounded with her choice of jeans that likely were her size when she was a teen, creating an effect similar to Rainbow's shorts, it did ring some bells.

All of their outfits rang bells, even Twilight's to a degree. Unfortunately for Spike's Mare Mysterious side, another bell was ringing a tad louder. Namely the one downstairs that was calling for room service quite insistently. It was good he hadn't changed into sweatpants yet or this would've been a bit more than awkward with the four mares in the room - one of which he considered tantamount to a sister or mother at times. Especially with her.

"Hey, Spike?" Twilight called out. "Would you be willing to let us mares have the library for the afternoon? We wanted to have some 'just mares' time." She said in a way that did Spike no favors. It wasn't overtly sexual - not in the slightest. Twilight just had the nonchalance of a firenado rolling through a firework factory. Her tone, completely innocent, had just enough twinge of guilt infused noninnocence that it was more than obvious that 'mare time' may mean something different to the four mares than they wanted the young dragon to get.

"Yeah sure!" He cried, stashing his comic before bolting out the door, charging down the way towards a random direction. He needed an excuse to be anywhere but near the four mares that had chosen to lightly fetishize themselves that particular day, and he wasn't about to miss an opportunity when it presented itself so plainly. Whatever they were doing, it was beyond Spike's purview. He wasn't innocent, which was all the more reason why he ran as fast as he could to find a nice secluded place to tend to the problem he was now facing.

Twilight blinked as she stared at the seat where Spike had been mere moments ago. She almost expected to see a puff of dust in his shape still there with how fast he ran away. She wandered to herself why he was so eager to run, but a knock on the backdoor broke that thought from her mind. Opening the door a crack, she smiled and let the pony in.

"Coloratura, glad you could make it!" Twilight said with a wide smile. The mare returned her smile and gave her a quick hug.

"I wouldn't miss it for the world!" She replied with a smile. "Plus, it worked out for my... schedule." Twilight nodded. Applejack didn't know, and Coloratura had made her promise that none of those here would be the one to tell her, that little 'Rara' was actually the up and coming star Countess Coloratura. It was an easy secret to keep since it kept her comfortable and Applejack wasn't big into any music that wasn't at least as old as Sweet Apple Acres. Their soirées were also good for the singer pony whose minorly overbearing manager could work the pony near ragged - though fortunately never beyond that point.

"Rara!" Applejack beamed, breaking from her conversation with Rainbow and giving the singer mare a bear hug that got a squeak from her. It did Twilight's heart good to see the two having fun - even if one of them wasn't being entirely forthcoming. Then again, both mares were somewhat secretive to the others - none of the other Apples, much less any other pony outside of this room, knew about the two.

Another knock at the door behind Twilight brought her attention back from her wandering thoughts. Peaking out the crack of a slightly open door, Twilight smiled again and let in Soarin and Big Mac. The two stallions politely greeted Twilight before moving deeper into the library house - Soarin getting tackled by Rainbow and Big Mac finding a Rarity wrapped around his arm. It was nice that they could all get together.

Her thoughts were broken by another knock. It was a good thing then that Twilight hadn't moved from the door - if for no other reason than to let in all the new arrivals. She cracked the door open, and a second later threw it open completely to give Flash a big hug - pulling him inside with the same. A brief wisp of magic later and the library was closed off from the rest of the world.

"I'm so glad you were able to make it!" Twilight said while still hugging Flash. The stallion chuckled, patting her awkwardly on the back as he did.

"I wasn't about to miss my summons from a princess." He joked with a withering laugh. Twilight batted him on the back of the head with a smirk that conveyed all that she didn't say. Meanwhile the other couples were getting to an end of their small talk - the evening's events seeming more important than catching up on weather, especially for those that lived near enough to one another.

Soarin was the first to talk up about this shortly arriving eventuality. "So, Twilight, are we going to get this par-"

"Don't say that word." Rainbow interjected, slapping a hand over his mouth to stop him from finishing the dreaded word. "Remember last time someone said that word? We couldn't get Pinkie out of the door for the entire evening until each of us played the less sexy version of Twister." Soarin's eyes widened and he nodded in horrified recollection. Never had Twister been so unsexy and so highly competitive than that day. His left wing still gave him issues on occasion to remind him. Left wing yellow - never again.

"So, Twilight," Coloratura began in Soarin's place, "are we going to begin shortly?" Twilight gave a nod, lighting her horn in preparation for the most complex spell of the night. With a burst of sparks, magical energy overflowed the room, sticking to the windows and any peep holes. Illusion spells were always fun, especially with how thorough Twilight was. A three dimensional illusion that filled the house and library from the outside, covering all angles in a visually consistent falsehood - no matter from what window or crack in the walls it was viewed from.

It might've been overly cautious, but it was also necessary - especially considering there was a princess, an up and coming singer, multiple pillars of the local community, a guard of decent standing, and a member of the Wonderbolts all in one room. If the actual activities that happened in the library were seen or recounted beyond it would not be the best thing for anypony involved. None of them needed scandal. What they needed was some good unclean fun.

Twilight, despite her usual level of shyness, was actually the first to begin stripping. It was less to do with the reticence of anypony in the group - as shown by Rainbow who beat the purple alicorn to getting naked despite giving her friend a ten second head start - and more to do with the unspoken rule that if Twilight was undressing it was a good sign that they all could. Her shyness was only a nonfactor when it didn't have to be - like when she had finished the spell.

Like a crack of lightning, the group was suddenly all naked. It wasn't odd for anypony in the group, the ceremony of it all something they were all more than well acquainted with. It wasn't a sexy stripping - unless the individual's voyeuristic tastes were also tied with one's enjoyment of speedruns. Everypony simply went from clothed - as much as they had been - to as naked as they could be as fast as they could.

Rarity was the first to begin the fun - unless one counted the eyes that Soarin and Rainbow shared - when she grasped the slab of meat that was Big Mac's Little Macintosh. Not very Little to be fair, with enough girth to require both hands to encompass it and more than two fully extended hand to reach from the base to the tip. He was by far the largest in the room - though the others weren't particularly slouches in equipment.

Soarin had a long, thin shaft on him. Its extension, though, wasn't quite so impressive with him being a shower over a grower - which had proven a problem for the skin tight getup he worked in. It had been the undoing of many mares who had seen it during a show despite his best efforts. Flash was... well, at party's he was jokingly called 'pencil dick'. This was because the pencil that had measured beside his member was a novelty one half the size of Macintosh's monster and it was funny to refer to his sizeable schlong as a 'pencil'. Twilight particularly liked to do so. The quite ones. Need I say more?

The stallions' equipment, of course, was not the only such weapons of war on display. Rarity, as might've been expected, was technically the most shapely as far as conventional standards were concerned. She was in eternal, secret conflict with Fluttershy and Pinkie for the title of the 'biggest bust'. It was, therefore, a sad reality the alabaster unicorn was unaware of that Fluttershy compressed her bust in uncomfortable getups to avoid the attention her natural size gave while Pinkie was... well some ponies swore they saw her adjusting her size without so much as a thought. The rumor was that her funbags had a possible mathematical relationship between their size and the amount of fun in the area - or even the world*.
*It is to be noted that Twilight has looked into this phenomenon. Through her preliminary investigations she has discovered that this rumor is actually quite true. The equation, as it is currently understood, is B=F3*([S2/M4]+[AR(b-n)+(p-c)/DSC+f]) Where B is her bust size in centimeters, F is the global amount of fun - the hardest measurement of the bunch to take accurately - , S is the number of Stallions within three miles of her, M is the number of Mares in a seven mile radius of her, AR is Average Rack size in centimeters of said mares, b is the number of mares wearing bras at the party, n is the number of mares not wearing bras at the party, p is the number of mares wearing panties at the party, c is the number of mares not wearing panties at the party, DS is Average Dick Size in inches of the stallions in a mile radius from her, C is the amount of Cakes in Sugar Cube Corner - including the amount that can be made with the prepared batter and ingredients available - at the time, and f is the Fun in a mile radius from her. Twilight continues her work to fine tune this equation, with current consideration to the effects of hermaphrodites, asexuals, and the number of ponies she has had sex with who are in attendance at the current party.

Beyond her rack, Rarity had the curves to match elsewhere. Her body was plush, yet firm where it counted. Applejack, on the other hand, was firm everywhere but her tits - which she could jiggle on demand thanks to her excellent muscle control. If Rarity was the perfect super model, Applejack was the perfect body builder mare - at least to some stallions and mares. Her legs were thick, set wide by her impressive hips. She, like her brother, was built better than a tank. Her muscles were impervious to scrutiny and were so well defined that they could serve as their own dictionaries.

Applejack's friend Coloratura was a modest filly - despite being naked. She was the type of body that artists throughout history painted without clothes on holding a vase or surrounded by cupids. A soft, gentle beauty unmarked by muscles or fat - except by a tiny bit in the bum and thighs. She was a looker, with tits that hung with just enough weight to reassure one that the artists wouldn't miss them. She was slightly smaller than AJ, though neither of them was particularly minding of the fact. They were well aware of each other's bodies from their many previous meetings.

Rainbow was the most amazon out of the group, with a few inches on even the farmpony - though her brother beat everypony. Her muscles weren't as visible, but her lithe form promised a great deal of power hidden beneath its surface. Her bust was certainly the smallest out of the group, with most ancient artist wondering how they were going to make sure everypony knew that those were boobs and not well muscled pectorals.

Twilight was the embodiment of the busty filly from down the street. More plump than muscled, unless her brain was in consideration. Her rack was ponderous, though a good bit smaller than Rarity's. Her ass - though she preferred 'bottom' or 'tooshie' - was, though likely not the biggest, the jiggliest. Applejack might've had her beat with absolute size, but muscle wasn't renowned for its bounce.

The stallions and mares reserved their attentions for their partners alone - especially Applejack and Mac who had only been roped in to this shared orgy because they had already been to one together, though that was down by deception and the application of a few mind altering spells on Twilight's part. 'Thank Celestia they hadn't boned while disguised' was the generally shared sentiment between the siblings.

Rarity slowly, as her hand slid up and down the impressively sized meat of her coltfriend, went to her knees like a true lady. Mac smiled brightly as she preformed what she considered her marely duty to her lover - though perhaps consort might've fit better. It was unfortunate from Mac's perspective that he'd have to let her down shortly after this, but it would've been even a greater unfortunate circumstance to let go of this chance to take advantage of the mare's expert attentions. It would be near the only part of the relationship he'd miss to be fair, but he was certain that despite it all they could be friends. Whether that would be the truth...

Applejack and Coloratura were in the next wave of those that got into it as AJ grabbed her marefriend and swung her around in a passionate kiss, letting the singer hang from her arms. It was cute how panicked the singer pony looked. Despite doing the same maneuver over and over again she was just so quick to panic when it came to AJ's antics. There'd be tongue involved in that kiss, Twilight knew - personal experience from their experimentation being a good guide - despite it not being visible.

Rainbow jumped Soarin like a cat behind the two kissing ponies, the two locked in a quick fuck. It was no secret that the two ponies were less lovers and more codependent-sex-addicts. Soarin had been with enough mares to be more than used to the feeling of sex - with nearly a new mare after every show - Rainbow was the steady one though. She was also the nearest mare that was willing to take dick without asking for bits. Rainbow, for her part, had a bit of infatuation for Soarin, though it was more her general idol worship for the Wonderbolts than anything that might turn to love after any length of time.

No pony was fooled into thinking that they'd be together any longer than it took for Rainbow to find somepony that was actually good for her. Soarin, of course, wasn't fooled either. It was why he was still married. Twilight didn't entirely approve of the extramarital affair, but she wasn't in a position to judge. Her infatuation for Flash had started in the other world - though she rarely liked to think of that weird world on the other side of the mirror.

Flash, for his part, was less than aware of the emotion of the room when it came to Twilight. He accepted the affection and the sex from a princess. He had assumed that she had heard about the size of his dick and that he might be the second guard to get married to a princess in as many years. Twilight, in a stunning departure from her usual strict adherence with customs and expectations, was less inclined toward marriage. Her possible immortality - something that not even Celestia or Luna had wanted to broach with her or Cadence, who was equally as likely to be immortal - kept her from more intimacy than the carnal pleasure of sex. Immortality didn't stop fucking from feeling good.

It was at this point during her train of thoughts that Flash grabbed her hand. "Are you feeling alright, Twilight?" He asked in a rare example of actually being able to read Twilight. She looked about at the party, a pang of regret flooding through her. She knew, as well as some others did, that this was their last hurrah. Mac was already lining up the next marefriend, Coloratura was going off on an extended tour, Rainbow had been talking more and more about ponies other than the Wonderbolts, and Flash was... well. To say that Twilight was pleased that teenage hormones had stayed on the other side of the mirror was an understatement - she just wished that the inklings of feelings she had developed for a Flash had stayed there too. Flash wasn't entirely healthy for her, she needed to move on and limit his role in her pleasuring.

"Just... thinking." Twilight said in partial honesty. She wondered if the rumors of Celestia having a harem were true and whether she might be able to get some pointers on how to get one of her own without any of those ponies catching on they weren't the only ones in said harem. She wasn't about to let go of Flash, but having more than one avenue for pleasure certainly was appealing.

"Do you want to start light or should... I dunno, your choice." Flash said. It was one of the things that ticked Twilight off in a small way - though never enough to get anger to rise. The Flash in the other world was assertive and confident, not to mention talented. The Flash she had easy access to was... bland and like a dozen other guards. He was less appealing in that way than store bought cakes - Sugar Cube Corner being the exception to that - at least those bland cakes might have happy memories of birthdays gone by attached.

"Fuck me, Flash." Twilight said finally with a complete lack of sexual energy, stuffing down any negative emotions she might've had along with any enthusiasm she may have had at some point. She planted her hands against the wall, lowering herself while spreading her legs out. Flash, never one to pass up princess pussy, dove in with gusto. His thick sausage scratched an itch, and was even better when Twilight imagined somepony with a little more personality behind it. A faceless stranger having his way with her was almost more enticing - but not something she ever wished on anypony, not even those that needed a little suffering of their own.

It didn't take much time or effort on anypony's part to work past Twilight's issues as Flash plunged deeper and deeper into his princess. The sensation of her insides getting spread wide around the stallion was enough to banish any negative thoughts or lack of enthusiasm that had stained her. She let herself go, screaming out Flash's name on reflex as she was fucked in much the same way she had let the teenager. The stallion behind her would never know that he wasn't the pony who she was saying the name of.

Rainbow, in much the same predicament as Twilight to a degree, moaned while biting into Soarin - who was into it - so hard it nearly drew blood and certainly would leave a mark if not for the healing powers that Twilight had practiced for their particularly rough way of having fun. Rainbow, however, wasn't doing this because it was her usual way of coping with pleasure, but rather because she knew herself. Lightning Dust would be the only name screamed. Damn that mare, she was a pain - but was she a fuck. Doubtlessly she had a trail of bodies of satisfied customers behind her a mile wide. That experience had been a bit of an eyeopener to the pegasus who was still thoroughly enjoying the railing she was getting.

Despite the powerful thrusts that satisfied her and scratched that deep itch that always pestered her, Rainbow couldn't help but let her thoughts float to her revelation that Wonderbolts weren't necessarily the best at fucking - though flying they were certainly aces in. Lightning Dust had, with one night of unexpected passion, tossed out all of Rainbow's notions on the inherent superiority of the athletes. She had gone from thinking herself so lucky to get fucked by a Wonderbolt to feeling exactly how the tongue of a skilled enough pony might result in a feeling more filling and satisfying than what this stallion was accomplishing.

Big Mac, on the other hand, was thoroughly enjoying the blowie he was getting from Rarity, whose well trained lips curled around every vein and bulge his dick threw at her. He loved the sensation of her mouth sliding wetly up and down - not to mention the knowledge that his stream of pre was gliding down the lady's throat. Lady indeed, Mac felt her more the whore. He'd never say it out loud since such things were rude in the extreme, but he'd always harbor such thoughts.

Rarity, for her part, simply sucked, happy to serve like she felt she should - like any mare who wanted to be marriable would. Mac thought himself the only one that wanted to end the relationship they had built - however shaky it was - but he was quite wrong on that score. Rarity loved the dick, but the stallion - much like his sister - was a piece of work she wasn't up to. She'd suck and fuck the dick like she was expected to, but she'd never marry herself to the stallion that it was attached to.

Beyond this room full of dysfunctional, collapsing relationships that had devolved at some point below even just 'fuck buddies' there were Coloratura and Applejack. Two mares, thoroughly in love with the other's bodies as much as they were in love with the pony that those bodies represented - which was very much. Applejack had progressed their fun to licking the other mare's pussy. The taste was familiar, homely. She loved it as much as anything else of the mare's.

Coloratura, biting her lip while her one hand played with one of her breasts and the other gripped AJ's hair, felt remorse tainting her pleasure though. Guilt over her long absence that was to come. She had no way to explain it that wouldn't bring more questions. She wanted this to last, but AJ was inseparable from her farm and 'Rara' was inseparable from her career as a singer. She didn't entirely enjoy the 'Countess' persona that her manager had been floating, but it did seem to work for the fans. This meant that, despite what she might wish, they'd have to be apart.

She would've cried at this, the sorrow of knowing she'd leave AJ flapping in the wind with little indication of why. She hated it. She wanted to be near, but she was being pushed away not by the other mare but by her career. She loved Applejack, and without a doubt would miss her for the duration of the long tour she was about to embark on. It was just a shame that the two of them were the only two of the assembled group that was likely to be true for.

The room was filled with the sound of pones in the throws of pleasure - sounds that never made it beyond the walls of the library due to Twilight's enchantments. Everypony let themselves melt into the pleasure, the concerns of the future gone for the time as they simply let themselves enjoy what their partner could give them. It was a symphony of hedonistic delight that lacked the edge of intimacy it once possessed. It was simply sex, and only AJ and Rara experienced anything deeper.

A Very Important Lesson

Spike sighed as he walked out of the doors of Sugar Cube Corner. The gem covered cupcake in his taloned fingers somehow not looking as appetizing as he had hoped. Puberty: it was something Spike thought was very bad.

It ought be noted for the sake of those less acquainted with dragon biology that pony and dragons are quite different. Scales that look like skin and fire breath - along with wings, eyes that could see sixty percent better in darkness, and the whole egg laying thing - were not the only things that set a dragon apart from ponies, and Spike was suffering deeply from this.

Ponies, by and large hit puberty at roughly thirteen years of age. Some hit it late, other can hit a second wave, but by and large the awkward dies off shortly thereafter - at least so it is to be hoped. Dragons, however, are very different.

At thirteen a dragon experiences mental changes similar to puberty, though on a much more subdued scale and with no real physical changes. By the age of seventeen, however, dragons hit their first real puberty. A being that lives on a scale of centuries and grows to enormous sizes could scarcely be expected to only hit puberty once, after all.

Reference material to all of this is scarce - most of it coming from one Twilight Sparkle and her assistant Spike - but it usually plays out towards dragons hitting five different sorts of puberty throughout their life time. First at seventeen or so, next at fifty, next at one hundred and fifty, then at three hundred, a particularly tough one at three hundred and seventy, and then the last - when a dragon becomes its full and ultimate self - at about five hundred years.

Spike was a late bloomer.

He was eighteen and getting hit hard.

His experiences in the previous year with getting hit by the enormous power greed has over a dragon's biology hadn't helped anything, and had only been a font of anxiety. When biological puberty came knocking, he freaked out. He was still actively freaking out to be fair, just on a longer timescale and at a lower boil.

Now his eyes were opened to the sexiness that his younger mind had hidden from him. What had once been curiosity at what mares hid under their clothes on par with wandering what you might get for your birthday, he now lusted - a very dangerous thing for a dragon to do. Lust, after all, is just sexual greed - or so Spike had been told and had believed. Suddenly everypony was either hot or not and he was his only arbiter in the matter.

His thoughts were both interrupted and amplified when three young, blooming fillies ran up to him. The Cutie Mark Crusaders were each attractive in their own way - and, worse yet, within his age range. At least they all dressed in more modest ways than their sisters... or whatever Scootaloo and Rainbow were - he never was sure.

He gripped his cupcake hard as they ran up to him all smiles - unaware of their bouncing boobs. Sure, they were small - except in the case of Sweetie - but they were still very there and calling his attention. The internal engine that was his sex drive never truly stopped being revved these days, but the three Crusaders tested how revved it could really get.

"Spike! Hey!" Apple Bloom shouted out, even though she was only a few stride lengths away. Spike fought back the blush as best he could, relying on his natural color to hide it the rest of the way. "Hey, have you seen our sisters? We've looked all around and haven't seen 'em anywhere."

It was at this point that a fork in the road was made. Such things happen in our daily lives at many points we may rarely fully realize. There was a world where Spike lied and said he hadn't. The sisters would meet later that evening and the world would keep on spinning on towards where it ought to have. At the same time, however, Spike was a rather honest individual who was also being hard pressed by three sets of knockers right in front of him that played in harmony to the bodies that still floated about his hind brain.

"Y-yeah." Spike stammered out. He already hated himself since he knew it would mean going back with them. "Yeah, t-they're at the library with Twilight having a... 'mare's night'. B-but we shouldn't bother them, they wanted their alone time!" He tried lamely. There was always hope that it'd work - and it had in about seven different universes. He simply had the misfortune of being in one of the countless sextillions that it didn't.

"Mare's night, huh?" Sweetie asked, looking at her compadres. "Well, we're mares!" She said, as if just realizing that they, in fact, were mares and not something else. A good thing to know to be sure. "Let's go!"

"B-but, their alone time!" Spike tried again, his nerves shaking profoundly.

"Yeah yeah, mares say we want space, but usually we're just checking to see if you care." Scootaloo waved him off. "Besides, we have to get these assignments done for tomorrow. I doubt they want us to fail our projects."

"Yes! I mean no! I mean... I... fine..." Spike muttered, letting out a great sigh of reluctance. There was no way to spin this that didn't end with a scolding coming his way - one he didn't need from a pony that seemed to be dangling goodies unwittingly in front of a hungry dragon. He could only hope that somehow this would all end well.

It would, but he didn't know that.

Spike knocked on the door of the library, already kicking himself for interrupting whatever it was that he was interrupting. Sure, none of the sisters would want their little siblings to fail their assignments, but having a pleasant evening cancelled was no good. Hopefully Spike would be able to just huddle in a corner with Mare Mysterious while the CMC did their assignment and just blend into the background.

A second longer than he expected later, the door creaked open, revealing Twilight's head peaking out through the gap. Spike couldn't help but notice that the one shoulder he could see didn't seem to have clothing on it. It didn't have to mean much, but it was just... not something he was in particular need of seeing.

"Spike, we really do need the evening alone, not just a few hours." Twilight said in an understanding voice that held no malice. It was good that that was the case, seeing as Spike was already feeling wretched.

"Y-yeah, I know, but I got... roped into this." He said lamely, not sure how else to express it as he pointed to the three fillies behind him that then took center stage.

"Hi, Twilight, Spike said our sisters were visiting you and Ms Cheerilee gave us an assignment that we need them for." Sweetie Belle said as she pushed forward with her friends. Twilight blinked at her for a second, still smiling as she tried to do the math in her head as to why they shouldn't do it now.

"Couldn't you... do it later, girls?" She asked, though it certainly sounded more like pleading in Spike's ears. With Twilight there was a fine line for these things, but even so he had learned the fine points of how to read Twilight like a book - appropriate considering who she was.

"It's due tomorrow!" Scootaloo chimed in. "Can you believe she assigns it one day and calls for it the next?" Twilight, for one, didn't. Especially since Twilight and Cheerilee had had a thorough discussion on the mare's lesson plan - more so because Twilight wanted to learn how she managed to teach all the colts and fillies of Ponyville when Twilight had trouble controlling a small group of them.

Her doubts in this situation were well founded. The Crusaders knew as well as anypony that Cheerliee always gave assignments with more than enough time to complete them. It was true that it was due tomorrow. It also so happened that it had been assigned well over a week prior and had been mentioned at the end of each day since. It also so happened that the Crusaders had been busy of late. With what could be summarized with 'stuff and things'.

"Alright, well, the girls and I are in the middle of something." Twilight tried once more.

"It'll only take a minute! We just need to ask them some questions about their 'jobs'." Apple Bloom said, proving to Twilight the futility of getting them to go away. The alicorn sighed, looking back into the library. A glint in her eye a second later told Spike that she had come to an idea.

"One moment, I'll go check with them." Twilight announced, closing the door and moving inside. The four of them waited, not sure what to make of this. The sounds of conversation could be heard faintly through the door, though somehow it felt more distant than just the inside of the library.

A short while later the four of them were entering the library. Spike blinked, feeling... something. A second ago he felt he was still outside the library, but now was inside lacking any memory of Twilight letting them in. She must have, and he must have said something to her - because he had been preparing a joke - but everything between being outside and then in was a blank.

Twilight and her friends were all about the room. It was on odd set up for whatever 'mare time' was, but none of the four were about to judge. Who knew what they were up to. After all, it wasn't the only thing to judge them on. They all seemed... flushed? No, that wasn't right. They seemed completely normal, and yet a tiny voice whispered in their ears that there was something up with the four mares in the room. Something that they could quite put their finger on.

Spike's ear twitched as something... or was it nothing? It twitched as a sound wasn't made and a response wasn't given. For a second he saw shimmer of something off, but it passed before he could truly grasp it. He sighed and just grabbed his comic.

Without another thought about it, he plopped into an odd chair he didn't quite recognize and began reading. The story was truly enthralling. Something tickled his hindbrain as he went on reading, but something always seemed to want to come up as he read his comics.

Apple Bloom did her best to concentrate as she asked her sister her questions. Something in her periphery caught her attention, and yet whenever her eyes flicked towards it it wasn't there. Something in her sister's disposition seemed... off in a way, and yet as soon as she tried to think in that way she couldn't figure out why she had had such thoughts.

Occasionally the air would seem to shimmer for the three crusaders as they asked their sisters. Sweetie, having finished her questions was having a particularly hard time understanding. She could hear Rarity encouraging her, giving her direction and instruction that she'd definitely take to heart, and yet for the life of her it was a clear as mud. She understood at some level, but the part of her that could think in words was having no luck in the understanding department.

Scootaloo was also falling prey to this to a certain degree. As she had entered something had been heard, and yet it hadn't - it was really weird. The entire time since had been in a sort of haze - and not just because she got to spend time with Rainbow Dash. She wasn't having trouble concentrating, but as their interview went on - and the world continued to refuse to come into focus - she couldn't help but feel that there was something she was missing.

The three of them that were actively trying to pay attention - unlike Spike who was content to read - all noticed it. Spike would've continued to notice it beyond when he had first entered had he not set about reading, but what might've been wasn't the point. Or maybe it was in a different version of this story.

As the night progressed the world seemed to flicker and shimmer like a poorly made reflection on moving water. Flashes of... something... no, of something they could all on occasion could place. Out of the corner of their ears they heard moans and groans of... well, the thing that went bump in the night. They each, at some point, thought they saw their sisters with... others. Mostly stallions that they thought for sure they could recognize when they were actually visible.

Scootaloo felt sensations she could've only imagined before in those brief glimpses. The feeling of something somewhere she rarely played with. It was amazing! or at least that was what she would've thought had she the ability to do so clearly and consistently. As such, some... force? Something was forcing her not to notice and to not notice she wasn't noticing after a moment.

Much the same was true for Sweetie, who was still learning, but wasn't sure what. Sensations filled small parts, and what visions peaked through were hard to decipher. When words occasionally punched through before being thrown back out of her mind she could've sworn they were instructions of a kind she had never received before.

Apple Bloom, for her part, was in a state. Her conversation with her sister after the assignment, not to dissimilar to her usual after work conversations, had... shifted. It was odd to say the least. Responses, questions, statements, and more were lost in a haze - as if from one moment to the next they had switched from actually talking to speaking in a dream. Words were muddled, meaning lost itself, and sometimes she swore she could see her sister a lot closer than she had ever seen her.

Each of them felt it, and yet couldn't feel it. The hidden sensations and emotions that worked just at the edge. The feeling of heat, of... of pleasure. It was there, but only in short glances. A quick peak soon forgotten. They might've thought, had those visions stuck around long enough to be thought on, that they might've had stints of daydreaming. Very odd daydreaming for Apple Bloom and Sweetie, but daydreams none the less.

Spike, however, didn't try and notice anything. He was content to read and read. The new issue of Mare Mysterious was good enough to absorb almost every stray strand of attention. His mind would occasionally itch with sensations that it forced upon him. His draconic mind, ever resilient - though not wholly resistant - against mind altering magic, was pinging something that he wasn't supposed to notice, but even so he shrugged and read. He didn't even need to sit while reading it. He could read it however he liked.

As he went on, something happened - likely a fantasy taking over. He couldn't help but imagine himself fucking Twilight - a thought that would've repulsed him usually but somehow was just beyond him to remove. He began to imagine dirty talking the alicorn. Saying things he'd never actually say.

"You like that, Bitchlight‽" He asked ferociously, his latent draconic instincts pushing him to extremes he'd never had gone to in real life. The fantasy felt so good, so true. It was wonderful! He couldn't even focus on what he was reading, but it was good practice to act consumed in it.

The world somehow became fuzzier and warmer as he came. He came! He could feel it as plain as day! He didn't stop though, the power of a dragon to keep going for days pulling him through. He felt thirsty at points, but in the end he just kept fucking. His biology took over and shut down everything that wasn't involved in fucking - or at least that was the fantasy. It was amazing!

On How to be Surreptitious

Rainbow shivered under Soarin's attentions as he ran his fingers through her hair while tenderly ramming his dick into her ass. She loved the sensation, but there was a reason she was biting down into her wrist. She loved how he stirred her insides, and nothing was quite like taking a load of spunk into any hole.

She did her best to forget that there was somepony better, somepony that showed her what pleasure was in truth. She tried to focus on the pleasure se was getting right now. There certainly was a great deal coursing through her, but all the same she sympathize with those mares in some of the soppy books that Rarity liked that were caught in the act of infidelity by screaming the wrong name while in bed.

It was easier than some of those stories made it out to be, but when the insides were stirred just so and the mind's rational quadrant was told to stand down in favor of letting higher quantities of endorphins flow through, it became harder to not scream out the name of the one that had acted like some Faustian deal maker when granting such blissful ecstasy but consigning one to the damnation of knowing no other could ever relieve one in quite the same way. Rainbow hated knowing she had found something better, but she did let herself enjoy what she had.

To prupose she thought about keeping Soarin around on the side while going stronger with Lightning Dust would be dishonest, as most of her thoughts were either consumed in the pleasure of getting railed and the rest were occupied with not saying Lightning Dust's name. If a third section was to be made in her thoughts it would've likely been thinking something along the lines of 'oh my gosh!' over and over again.

Rarity had, in the time that had passed, switched from simply giving a blowjob to her stallion to sandwiching his large member between her plump tits while suckling at the tip. Big Mac, with all his stoic energy, had his eyes closed with his hands clasped behind his back - having long since learned that to touch Rarity's hair wasn't a move that ended well.

Her expert technique a her luscious lips curved about his shaft with slick, pleasurable smacks sent thrills through Big Mac. With a groan, he felt his first load of the evening coming up. Rarity noticed this too, and so dove forward, sealing her lips against his crotch while his long dick was forced deep inside of the fashionista's tight throat. Big Mac shivered slightly as his dick pumped Rarity full, sending a torrent down her throat.

Bic Mac sighed, pulling out of the warm confines of Rarity's throat. A thin tendril of spit mixed with spunk connected them for a moment longer until it snapped, thwapping down Rarity's chin. With a dainty finger, she swiped it away and restored her pristine appearance to a small degree.

Twilight groaned as Flash railed her ass, diving in and out at a steady rhythm that drove the princess wild. She could imagine the confident and cocky Flash, still wearing his leather jacket, as the one grabbing her rear and slamming his sizeable shaft inside of her. So long as the pony behind her kept his trap shut the self imposed illusion was pretty easy to keep up.

He plunged on and on, in and out, the sound of smacking flesh echoing in chorus with both ponies' sounds of sexual jubilation. Twilight imagined for a moment what might happen if she clouded his mind and made him think she was just a harlot to take advantage of. She wondered if he'd take the charge she wanted him to, if he'd claim her like some whore needing a good dicking. She might try it later, just to check.

With a growl, Flash pulled out of Twilight and sprayed his load across her back, gaining a shiver from the princess as the goo settled across her. Her orgasm fired as she quaked, sending her into ecstasy. She slowly calmed down, cursing herself as she waited for the inevitable.

The slightest bit of hesitation holding him back, Flash stepped back and bent over the mare he had just fucked in the ass - his dick still leaking the occasional drop of cum. Extending his tongue, he licked up his load from Twilight's back with long, lapping strokes of his tongue - making sure to catch every drop. He then went to his knees and licked up the few drops that had fallen from his shaft as he had worked.

Finishing his work, he looked up at his princess, his still hard dick in his hand while he knelt before her in adoration. Twilight would've been lying if she said she didn't enjoy it. A weak willed stallion debasing himself by cleaning her up with his tongue - it sent shivers down her spine. She didn't want it to, but it did. She also didn't entirely want him to do what he had, but being an alicorn meant certain things were in your control, while others firmly weren't.

"I am at your command, Mistress." Flash said, head bowing as Twilight looked back toward him. She had learned of this the first time they had had sex. Part of alicorn biology, it turned out, included a hormone that released during copulation that turned whoever the alicorn had been with into a temporary slave of sorts. It was a blessing it only affected somepony within half a meter of the alicorn, but it did mean she had this to deal with every time she fucked - or, more specifically, came.

Biologists don't know about this odd tick of alicorn biology due to the fact that they usually aren't the ones to fuck a princess or be near a fucking princess - both meanings of 'fucking' holding fairly strong in this case. If they had knowledge of it, it'd likely be a mystery of modern biology that papers would be written about for decades to come. It might've been theorized that it had developed out of a necessity to allow alicorns - which make up such a small portion of the total population - to create enough offspring as possible.

It might also have been explained away as 'it's magic and we're scientists' - which generally ends most discussions about such things.

The first time it happened was extremely destressing, especially since it had been vaginal. Doing it in the ass and then coming from that only hit the other pony for about ten minutes or so. Doing it in the vagina meant that the other pony was the alicorn's thrall for, on average, anywhere between half an hour to three hours - depending on the intensity of the alicorn's orgasm. Twilight, having been pent up at the time, had had a very powerful orgasm. Flash had by fucking the princess landed himself as a slave for the next TWELVE HOURS. Celestia had some interesting letters sent her way that day.

It was unfortunate, therefore, that though Twilight hated enthralling Flash, she was still very horny and wasn't quite thinking straight. "Eat me out, Flash." She ordered huskily as she turned about and leaned her back against the wall she had supported herself on while getting her ass fucked. Flash, with no will of his own left, moved forward and began to eat out the alicorn with pure devotion - netting himself servitude for the next few days without realizing. Sure, the effect of complete enslavement would die away in about half an hour, but he'd still be completely devoted to his princess - his mistress.

Neither pony knew it, but Flash had undergone what Celestia and Luna referred to as the 'ordination'. He was imprinted on by Twilight, who'd - whether or not she wanted it to be so - be the center of the unicorn's world. He was wholly dedicated to her service. In fact, a few months later he'd be transferred from the Crystal Empire to Twilight's Castle - once it was sprouted from a magic box - and would be the founding member of the Second Royal Harem, the First being shared unknowingly between Celestia and Luna who had similar enough tastes in ponies and varied enough schedules that the same group of ponies fucked - or otherwise pleasured - both princesses.

That, however, was something to come - much like his mistress was about to for the second time that afternoon.

Applejack kissed Coloratura deeply, sending her fingers to dance across the other mare's lower lips. She always teased her Rara with the joke 'You know how to sing, but only I can make you sing!' This was, in fairness, a pretty good assessment. Rara sang into AJ's mouth a song of pure sensual desire, her attempts to reciprocate the farmpony's efforts failing as her whole body writhed happily under the orange mare's ministrations.

Rara hit a particularly high note as she came on AJ's fingers like she had so many times before. She fell limp, panting as she rested in her afterglow - only to be accosted by Applejack's onslaught once more. Rara couldn't help herself as she screamed amelodically in the throws of passion.

AJ smiled to herself, her fingers dancing about her mare's insides with expert precision. Her well muscled body might've been build for hard labor, but her fingers were still as nimble as a harp players - something she may have to thank Aunt and Uncle Orange for. It might've been years ago, but those few harp lessons she had had were certainly helpful in some very interesting ways.

It was in this combined moment of passion and lust that the sound of a knocking at the door came. Nopony had expected it, as well they shouldn't have. The library was closed, most ponies were heading to their homes, and all food had been bought and stored in the library before the festivities had begun - so no pizza delivery ponies. There was no good reason that could be easily thought of that explained why there was anypony, or otherwise, at the door.

Twilight, the ever dutiful host, was the one that decided to answer the door. "Stay." She commanded Flash as she walked away, the unicorn bowing his head in response. She might not have noticed it, but several of her guests were noting how easily she could command the enthralled Flash - how naturally it seemed to come to the alicorn. She'd realize soon enough, but that would be something that happened outside the purview of this story.

Twilight opened the door and talked to whoever was on the other side, all the other ponies on the other side of the door quieting down as best they could. A few moments later, Twilight turned back to the group with a wide smile. It was a smile that several of the girls were acquainted with, one that spoke volumes that they'd rather not listen to if they were to be completely honest.

"Who was at the door, Twi?" Rainbow asked, already bucking into Soarin who didn't mind the attention.

"The Crusaders and Spike." Twilight answered, beaming despite the implications that everypony else was aware of. "The Crusaders say they have an assignment due tomorrow and that they need you three," She pointed at Rarity, Rainbow, and Applejack in a swooping gesture- all of whom looked aghast at this, "for an interview of sorts."

"Well, everypony get dressed and ready to leave, seems like we got work to do." Applejack said with a sigh as she stood up, helping the disappointed Coloratura to her feet.

"Oh, but we don't have to stop!" Twilight said a bit too cheerily. The other ponies in the room looked at each other in confusion, and then back at Twilight - their looks saying what all of them wanted to scream at the alicorn. "Remember the disguised p... fun we had?"

"Yeah, but some of us are related to those fillies." Applejack interjected.

"And you aren't related to Big Mac?" Rainbow said, already warming up to the implied idea. "It might just be me, but I think having sex so close to them might just be the hottest thing we could do!"

"I'd rather not them think I was just having sex with some random pony." Applejack countered, not at all plused by the suggestion. "And if you disguise me too... well tat just means 'Twilight has some random ponies having sex in her house.' It don't look good either way."

"I don't have to make ponies look like ponies, though!" Twilight exclaimed happily. "I can even make us look like we aren't having sex! We'll look like we're just sitting around fully clothed doing completely normal things! They won't even see where we actually are. It's perfect!"

The ponies in the room all paused, considering this. Regularly, Twilight wasn't one to suggest such lewd activities, but she had her reasons. Her heart pounded in her chest despite knowing her plan - with the proper application of magic - was completely fool proof, and yet she was ashamed with herself to even have thought such thoughts. This fact was exacerbated by the fact that it was thought around Spike. Spike - the dragon who she knew was going through puberty.

This all in consideration, she usually would've called it off just as Applejack had suggested, but today was different. It was the last possible time to get many of these ponies together. After that somepony would have to be left out after a relationship ended. She could feel it in the air that only Applejack and Rara were actually interested in each other beyond the carnal desires of the flesh.

The ponies before her were either shortly to be separated or just partners of convenience - the convenience of which was running out. They had to make this day count, they had to make it last. Twilight was nervous of course, the possibility that her concentration might slip while casting the spell and allow brief glimpses into the truth for the ponies and dragon that were about to enter was a looming specter. It hung over her mind, and yet was only just fended off by her duty as a host of a dying party.

"If everypony else is up for it and Twilight is sure it won't go awry... well..." Applejack muttered, more so to herself. Coloratura leaned into her, hugging her marefriend's arm - which pressed her breasts against the well-muscled bicep.

"Let's do it, AJ!" She pleaded with a smile - her own guilt about this being her last time to be with her marefriend for the foreseeable future pushing her quite hard. AJ shook her said with a smirk, throwing up her one unburdened arm up in defeat. Rara jumped up and down in excitement.

"Alright, so it's settled. You all can get into whatever position you like." Twilight said, clapping her hands as she gathered her courage up for what she was about to do. "I'll be back in just a second."

She grabbed the doorknob and took a deep breath in, before casting a quick extension to the illusion spell to form a dome on the other side of the door. She'd have to let the four of them in, and that meant the door would be opened fully. That, however, didn't mean anypony else had to see inside. The four she was letting in were enough already, she didn't need oglers catching anything of a glimpse.

She then opened the door, realizing as she did that the extension of the illusion field had meant that the four on the other side of the door were inside the unaffected portion of the spell wall. They all stopped - even Spike who was obviously winding up for a joke in his own way - now entranced by the sight by the view of Twilight completely naked before them. Her horn brightened in a quick spell, binding their minds much like she could freeze their bodies. She hated doing it, but it was necessary.

A quick wisp of magic later and Twilight was fairly certain she had removed the image of her naked from their collective memories. She took a breath, and with another burst of energy, sent a wave of purple energy cascading through their minds and eyes. Twilight shook her head at how sloppy she had been. This was already a mess, she could only hope that it didn't devolve any further.

"Come inside." She ordered the impaired ponies and dragon. They all obeyed wordlessly, letting her close the door without any more delays. As she locked the door behind them, she removed the brain freezing spell, letting them resume from where they had been. The effects of the missing time shouldn't be too much, so hopefully none of them had noticed anything too odd.

Turning towards her friends, she smiled to herself. Applejack was sitting on a rather comfy chair, legs spread to allow Rara access to her pussy. The sounds of lapping were easily heard by Twilight, though she knew none of it would reach the four visitors. Rarity was on the table, bouncing up and down on Big Mac's massive cock. Her moans of pleasure would also be voided by the spell, though Twilight wasn't so sure about the expression. Flash was, obediently, sitting on his knees with his head down and dick erect. Rainbow and Soarin were... oh sweet Celestia.

"Heya, Scoots, I'm fucking right in front of you!" She said with a wide smile. She was, indeed, both fucking and fucking in front of Scoots. Scoots didn't seem to respond to this, much as Twilight expected. Soarin slapped Rainbow's rear, continuing to fuck her doggy-style right in front of the girls and Spike.

"Alright, girls," Twilight began, gaining their attention, "Go to your sisters and ask your questions. Hopefully you'll all be done about the same time if you start at the same time. Please do make it quick." The three fillies looked up to her and gave her their renditions of a strained nod. It was obvious that their minds were bucking and champing about under the spell - and worse yet seemed to be able to send some signals around its barriers. Each of them was blushing furiously, though doubtlessly they weren't entirely aware of this - or at least weren't sure why they were.

All the same, they seemed willing to just go off and ask their sisters the questions they had come to ask without any problem. Twilight would have to be careful and watch them closely. At least, that was what she had thought until she was Spike settling down on Flash's lap with a comic book in hand. All at once, Twilight seized up as her mind froze and accelerated all at once.

He... he didn't realize? He didn't realize! He was willing to just sit on the stallion with the stallion's thoroughly erect dick sticking out between his legs. It was a scene so lewd that it temporarily broke Twilight as her mind raced with all the possibilities that it presented. So many things could now be done that she couldn't have managed. A dragon in puberty whose attempts at discretion - though appreciated - had not entirely worked. Spike was in need of release just as much as any of them. Perhaps the same was true of the fillies?

She decided to test her luck as she walked up to Spike while focusing her magic to make sure he saw her elsewhere. She brushed a hand down his cheek and barely got any reaction. There wouldn't have been anything to react to in his mind, though she could feel his heart rate increase. No matter how strong the magic was there'd always be something to get through. That was, at least, what Twilight comforted herself with as she pressed her luck.

As the dragon flipped a page, Twilight ran her hand across his lap. Beneath the cloth she could feel his dick getting harder. It was amazing to think that just an infintesmaly small distance below there was a throbbing member in need of attention. Twilight's heart quickened and her hand trembled as she fought with herself over whether or not she should go through with it.

She had read books about... things. Did any of them truly apply to this? They weren't even step anything. She was technically his legal guardian - though that status had expired for the most part when Spike had had his eighteenth birthday. She wasn't his mom, his sister, his... anything. He was her number one assistant but... what did that count for? Did that mean there was an expectation of sexual distance as with a family member, or... did the precedent that AJ and Mac had set give her license? She wasn't going to have sex with him, but maybe just... fun?

Something in her switched on, and the decision was made. She took a breath in and gathered her magic and altered the illusion spell she had implanted in the four before also freezing them once more. She stood up and looked at her guest who all looked at their sisters with worry.

"I've frozen them for a second to make an announcement." Twilight said with a faltering smile. "I've made some... changes to the illusion."

"What kind of changes, Twilight?" Applejack asked, already unsure to begin with but now even more unsure.

"Anything you say to them or do to them will be seen as normal." Twilight began, gauging everypony's response. "You can order them to do anything you like and they'll obey and not even truly register what you actually said. You can do anything to or with them that you want and they'll still see you as sitting in the seat in front of them - or whatever makes sense and seems less... sexual."

"You mean... we can... tell them to undress?" Rarity asked, looking at her frozen sister with a great deal of trepidation. The beauty inherited from some distant line of the family by both sisters was just as strong - though still in the process of blossoming in the younger sister - in Sweetie as it was in Rarity. They both had curves, some subtler in one than the other, and both were stacked in the asset department. Sweetie was a beauty, no denying it, but she was also related.

"Yes, and they wouldn't even notice the change." Twilight said, not having much enthusiasm to put in her voice as she did.

"Haystacks to just getting undressed!" Rainbow cheered. "You mean we can fuck 'em? You mean we could have 'em fucked in front of us and they'd just do it?" She asked with all the enthusiasm Twilight lacked and more. Twilight slowly nodded. "Heck yeah!"

"It... would be an educational opportunity that I'd otherwise not have with Sweetie..." Rarity conceded reluctantly. Big Mac looked at Sweetie, clearly a bit grateful that it wasn't Bloom. There were lines he wouldn't cross - or at least said he wouldn't. The chips had never been this down before.

"I mean... I... I rather not do anything with Bloom." Applejack weakly countered, looking into the eyes of her lover who was still between her legs.

"Don't worry, my sugar cube, I'll take care of her." Rara said with a cheeky smile, giving AJ's pussy a peck that sent shivers through the farmpony. This quelled all opposition in the mare.

"Alright, we'll start up the fun again!" Twilight said, feeding off the room's acceptance to gain a few ounces of enthusiasm. A burst of magic later, she unlocked the four minds. Spike blinked a few times before returning to his comic with a sigh. Evidently he had some ability to notice that something had changed - that time hadn't progressed in its usual path - but had decided to ignore it for the time being.

Twilight gathered herself together and looked at her ward. "Spike, stand please." She half ordered. Spike, without acknowledging the order, stood up while he still was reading. Twilight felt that tingled that occasionally struck her when Flash froze in obedience. There was something in her that pled to her to... to dominate. To take satisfaction from somepony being under her. She hated it; yet something in her loved it.

"Spike..." She hesitated, fighting with herself. She wanted to stop, but to stop meant to end this - to end the last time they'd all be together. Her battle had been decided before it had been fought, and so she sighed. "Spike, take off your clothes." Spike, without a care or notice, threw his shirt off, shirked off his pants and underwear, and then went back to reading.

To Twilight's surprise, the dragon was... was large. His dick was easily the same rough size as Flash's. He also had the benefit of being naturally well muscled - much as any dragon was. His inattention to his own state of undress was also enticing, as if he was so confident he was wanted that he didn't need to present himself to others - which was as far from the truth as it could be.

"Spike..." She tried to fight again, the small part of herself flailing against the oncoming storm of lust. It was a losing battle - no, a lost battle. "Spike, I want you to masturbate." Spike, as always, began to obey without hesitation and without noticing what he actually was doing. His right hand left the comic and began to run up and down his shaft. His hand pumped up and down, swirling briefly about the head each time he came to it, before going back to the shaft.

Occasionally his hand would dart to tease his hefty balls, but in the end he always was moving up and down. He had developed a surprisingly complex technique that likely was designed to grant him the utmost pleasure. Twilight idly wondered as she watched in rapt attention if she had achieved the utmost pleasure in her own masturbatory ritual. Thoughts for another time.

"Stop, Spike." She ordered, her mind awhirl with ideas. Spike let his hand drop to his side. Twilight noticed the glint that caught his hand - knowing full well what caused it. Without thinking, she grabbed his wrist and lifted the hand for inspection. She looked over it, examining how the pre on his finger caught the light. Without actually intending to, she brought it closer while letting her tongue extend from her mouth.

With a tiny, nearly imperceptible, flick, she lapped up the small dose of precum from the finger. The taste hit her, and though she didn't truly take the time to taste it, she immediately knew she needed more. She fell to her knees in an instant and drove her face down on the dragon's shaft without hesitation. Her tongue swirled about it with adoring tenderness and needing ferocity.

She loved the taste, the texture, and even the temperature - which was significantly higher than Flash. She slurped at it, tasting it as best she could - swallowing every drop greedily. Each drop, each taste, each splendid morsel that hit her increased something in her. She felt heat, she felt a strong, overwhelming urge that built up ever faster. As she worked, she realized she could better use this opportunity. She could... she could...

She popped the dick out of her mouth, whirled about on all fours, and looked back towards Spike who stood there with a drool drenched schlong. "Fuck me, Spike! Fuck me hard!" She pleaded. "Flash, get over here and fuck my throat! Oh please, I need it so bad!" Spike didn't flinch, but carefully set the book to the side and then lined up behind Twilight before plunging full force into Twilight's winking pussy.

She screamed, and was subsequently silenced as Flash thrust his dick into his princess' maw. Twilight's eyes rolled up in pleasure as she suckled at Flash's dick while thrusting herself back to meet with Spike with all the more ferocity. She adored this feeling. Nothing would ever compare.

Of all the things that could've been left out in biology text books about dragons, it would forever be the undoing of the uninformed that dragons had, much like alicorns, a special biological power. Their precum and cum were both, at varying levels, powerful aphrodisiac. No pony who fucked a dragon ever mentioned this because they were usually too busy fucking the dragon until... well, it depended on the dragon's particular attitude.

Alicorns and dragons. Who knew? Alicorns only had the effect attached to their cum, while as dragons had it attached to pre, and even - to an extent - their musk. Yes, even their musk had a minor version of this power - which might've explained why Twilight had become ever so more open with her friends about sexual things and her friends with her at about the same point Spike hit his first puberty. Of course, this might have all been a gigantic coincidence and Spike's increased production of musk and occasional sessions of relieving himself in the library's toilet may have had no effect on the mares and their stallions. The world would likely forever be deprived of the answer.

Meanwhile, Rarity had been having the most enlightening discussion with Sweetie. While as before the expansion of the spell she had simply been fucking Big Mac, things had since stepped up a few notches. It was to no pony's surprise that Sweetie was the most studious of the three friends, and as such had devised the perfect questions to get all the answers she had needed as fast as possible. This left time now for more interesting lessons.

"Now relax your throat, darling, a true lady - and even a decent harlot - knows not to apply bile to their stallion's unmentionables." Rarity encouraged Sweetie, who now had Big Mac's long and wide dick partway down her throat. Sweetie, for her part, still wasn't exactly absorbing what was happening as such - but some deep part of her mind that might reawaken at some point had taken the lessons to heart. She was doing her best without actually realizing what she was doing her best at.

"Now use your tongue if you can, even if its only to swipe along the bottom of the shaft. If you can curl it to reach the top that is wonderful, but don't strain yourself. Stallions would rather to have a long, though slightly lacking, show than a few seconds of immaculate joy followed by a hospital visit." Rarity coached, petting her sister.

Despite her question earlier, Rarity had elected to not strip her sister - not wanting to cross that road yet. Maybe at some other point. Something in her was growing, and she knew it, but for now she was in control and didn't need something... else.

Even so, Sweetie was providing a good example of skill in oral stimulation. Big Mac clearly appreciated it. Rarity continued to coach her little sister, her nethers growing hotter and hotter as she did as the air filled with a heat unknown. It never occurred to her that it might've been attached to the growing sounds of Spike railing Twilight.

Rainbow, for her part, was enjoying this to the maximum - as was Soarin. Soarin, at Rainbow's behest, had begun to ram Scoots' rear. Scootaloo was doing her best to write down Rainbow's answers down while getting fucked, but even so her naturally messy writing style wasn't done any favors with the fucking she was getting.

Rainbow loved it, the sight of little Scootaloo getting unknowingly fucked was just too hot. She had been schlicking herself to it the entire time, content with the knowledge that she was safe to do so without any repercussions. Her inner lust growing certainly had helped, but she would've done it without that provocation.

"Mmph... a-and, what do y-you do then, Rainbow?" Scootaloo asked through the pleasure her mind was magically compelled to not completely acknowledge. Rainbow smirked and let a loud groan out as she toyed with herself.

"Well then you gotta add more water, unless of course you're just aiming for the white and puffy stuff." Rainbow replied with the utmost composure. "You gotta be careful, though, since if you add too much it might cause the cloud to backfire in the machine and short it out. Then you'll have to wait for repairs, and that'll take weeks." Rainbow loved how flustered Scoots looked as she wrote down the answer. It was just wonderful eye candy for the mare.

On the other side of the room, Apple Bloom was trying her best to just have a normal conversation with Applejack. Her assignment had been technically done before she had even entered the library, but she just needed to cross check it to say that she had actually interviewed her sister. After all, they both shared the same job.

Unfortunately for the normalcy of the conversation, Apple Bloom was struggling against the tongue lashing Coloratura was giving her - a lashing she wasn't allowed to recognize. Her face was redder than Applejack had ever seen it, and despite her initial reservations, she was now itching for her own stimulation while watching her sister getting eaten out. She didn't know why she felt so hot and bothered, but she couldn't deny the truth of her situation.

In a moment of unbidden need, Applejack jumped up, broke the distance between herself and her sister and grabbed her head, planting a passionate kiss on the filly's - no, young mare's - lips. She savored the taste, her tongue invading the younger pony's mouth. She closed her eyes, letting her passion and pleasure guide her.

Rara, taking the hint, lift a hand to help AJ with her need, teasing the farmpony's pussy. AJ moaned in response. Apple Bloom, meanwhile, simply seemed to freeze as her magic addled brain tried to understand what was happening without actually showing her what was happening. Her brain was a mess of chemicals and magic, and none of it seemed to work together properly.

Grabbing the hem of the shirt she had let her sister keep on, Applejack threw the cloth up and over her little sister's head, panting hungrily as she parted for the moment. Her hands found the blossoming breasts of the younger mare, teasing the perky nipples that jutted out towards her. Her need soared, and she couldn't handle it.

Twilight moaned into Flash's dick as it shot jets of spunk down her throat. She loved this. Something had taken over, and now all she could think about was sex. Spike behind her, with a tweaking of the magic, was now proclaiming his need for her - even as he didn't realize what was happening.

"Fuck, Twilight, you're so tight!" He exclaimed as he rammed her unyieldingly. "FUCK! I'm going to have to fuck your pussy more often!" Twilight shivered in needy desire at the thought. The feeling of his rough cock inside her sealed her desire and choice before the question had been formed properly in her mind.

In the coming days the debaucherous scene would be a fairly common one - and soon one that didn't require magic. Spike would never be called part of the harem. No, he'd be the second party for which the harem was formed. The secret harem would, for reasons beyond the public's understanding, be the reason why some of the most eligible bachelors and bachelorettes in Ponyville and environs remained - at least publicly - bachelors and bachelorettes.

In a rush, Spike released his unaware load into Twilight's pussy - painting her insides white. She loved it, and even as she was rattle from head to toe by her strongest orgasm yet she knew she needed more. Fortunately for this desire, Spike didn't stop and continued to thrust without regard for anypony. It struck Twilight as odd on some level. Usually after the first dose of her cum the pony or otherwise would - or at least should - become blank, lick up the after effects, and then await orders.

Dragons and alicorns. Who knew? Species that had developed so similar mechanisms to ensure their low breeding rates always resulted in the highest yield of children also had, in so doing, gained partial immunity to each other. Alicorns less so, but dragons almost completely. Sure, if Spike had been aware he might've felt a preternatural inclination towards pleasing Twilight after the magical femcum splashed over his dick - but beyond that he'd be his own dragon.

Across the room, everypony as a wave felt a version of what Twilight felt. A burst of powerful arousal, of deep satisfaction, and - most unfortunately, or perhaps fortunately - submission. Big Mac, submitting to his pleasure and the ministrations of Sweetie released his load into the young mare's mouth. Sweetie, submitting to the stallion in her mouth, swallowed dutifully and came herself without stimulation beyond the torrent of ejaculate down her gullet. Rarity submitted with a loud scream of pleasure as she came all she had inside of her and more.

Rainbow submitted, pressing her crotch fully to Scootaloo's mouth and came as Soarin submitted in his way and hilted in the same little pegasus and unleashed his load. Scootaloo submitted fully and took both loads dutifully, lapping up Rainbow's sweet nectar while working her ass with unearned skill around Sorain's dick.

Applejack, the willful mare she was, still submitted as she deeply kissed and worshipped her younger sister while twisting her own and Apple Bloom's nipples with one strategic movement while cumming across Coloratura's fingers. Apple Bloom, submitting as best she could, came and kissed. Pleasure overflowed her as it never had before, and yet the magic blocked it from fully taking hold in her conscious thoughts. Coloratura submitted, as was her nature, and gave her two ponies the best she could while cumming herself as they'd have wanted.

The ponies slowly came down and settled into an afterglow like none they had ever had, only to find themselves cumming once more a few minutes later even as they rested as Spike came inside Twilight once more. This process repeated until Spike collapsed from exhaustion.

It was unfortunate he had been very pent up and was naturally vigorous as far as dragons went. It was also unfortunately that the lower end of dragon stamina at his age meant that they could keep fucking for seven hours. Despite the CMC's best efforts, it ended up they all had to turn in the assignment a day late. This, of course, would be helped by the secret they all never had to keep for never having to know it - at least until Twilight got enough nerve in her to not use the illusion spell.

Life, as it stood, was good. Life, as it was shaping up, was great. And it all had to do with a little surreption and the unknown effects of various species cumming. Puberty: it was something that led to other very good things.
