The swiftly darkening skies to the west could only mean one thing, there was a storm, probably a hailstorm, coming in. The underside of the thunderhead was just becoming visible over the steep headwall of the valley, its boiling dark greenish underside of ragged clouds was constantly being torn apart from the raging winds.
Twilight Sparkle sighed in exasperation as a jagged bolt of blue tinted lightning struck one of the higher pinnacles of rock along the valley ridge. It seemed that the good clear weather this year’s expedition had been lucky enough to enjoy while making the mountain trek to this location and setting up their semi-permanent research camp was about to come to a swift and blustery end. She stood stoically on a large flat-topped boulder, back legs spread slightly for greater stability, mane and tail hair whipping in the strengthening wind. She looked down upon her expedition’s camp situated on one of the few relatively flat areas clustered near the large swift stream that inhabited this valley’s floor, it’s white and frothy tumbling flow crashed over massive boulders and swerved violently around still larger ones. This minor torrent provided the best supply of pure cooking and cleaning water that a wilderness camp could hope for.
Though this was the third archeological expedition the newly ascended -it had only been eight years ago- Princess of Friendship had led, it was the first to come so deep into the interior of the Unicorn Range over a thousand kilometers from the familiar rolling hills and quaint villages of the Celestial Valley. However, Twilight forcibly reminded herself, as chilly and apparently stormy as this place may be she was glad not to attend yet another expedition into the arid, often desolate region south of the Everfree Plains. It wasn’t the location itself that put her on edge; it was the city that had been unearthed there five years prior. Perched amid the crumbling dusty plateaus it had been a fortress not only built by and purely for the Unicorn race but a city built after the Celestial Ascension, after the foundation of Old Equestria nearly two thousand years gone. A city purposely far removed from Alicorn rule to allow the inhabitants to continue in their remorseless ideology of racial purity that had infected the Unicorn Kingdoms of old for thousands of years. Twilight figured she would likely spend the rest of forever being unable to forget the discovery of the self-inflicted horror that had eventually overtaken that eternally damned place.
Shaking herself mentally to be rid of thoughts of such distant yet unsettling locations Twilight turned her attention back to the newly erected camp. It was overall, Twilight decided, a good campsite considering the difficult surroundings. Comprised of near on fifty, one to four-pony tents of various shades of brown and green fabric arranged in rough concentric circles around a trio of larger tents. A dining tent, a meeting and equipment storage tent, and a somewhat more ornate tent provided by the Chrystal Empire that Twilight would be sharing with her dear friend, childhood filly-sitter, and occasional lover, Princess Cadance. Cadance’s company at least would be enough to keep Twilights spirits up no matter how many storms she would have to put up with.
Truly if it wasn’t for the frustrating propensity that the central Unicorn Range had for generating powerful autumn thunderstorms that had a nasty habit of appearing over the mountain peaks with almost no warning and producing hailstones large enough to give serious injury to a pony so unlucky as to find themselves stranded outdoors, she might even have gone so far as to consider this valley an unusually good place to come on vacation this time of year. What with the leaves of the Aspen Trees beginning to turn their famous blazing yellow. Incidentally this weather phenomenon was why all the members of the expedition, not just those ponies hired to help with carrying supplies up into the valley from the tiny villages forty kilometers back down the steep trail, but also the archaeology members themselves were rushing around like flustered chickens busily securing equipment and reinforcing tents before said items could be beaten down and blown away by the powerful winds and hail of the quickly oncoming storm.
Well, the Princess of Friendship decided with another sigh as she shook her mane and turned back to descend the path down to her large circular tent, it seemed that her planned early evening excursion up the precarious switchback trail to the dig site would have to wait until the first light of the morning. She hadn’t even been here at camp for more than eight hours and already her meticulously detailed schedule was in for a complete revision.
Princess Cadance looked up from her investigation of some promising looking mushrooms growing between two moss covered boulders perched above the roaring stream five meters below. She could still see in the fast dimming light the lone violet furred figure of a young Alicorn turn off of and walk down behind a large flat boulder a bit above the arranged tents. Cadance smiled to herself as she resumed her progress toward camp having decided that fat brown mushrooms, no matter how tasty, were not worth getting caught out in a storm over. It was the Alicorn with the light purple coat who was responsible for her smile, as it had been far too long in her estimation since she and Twilight had been able to properly spend time with each other. It had taken a good few years of careful attention and guidance but the Chrystal Empire was once again becoming able to function under its own governance without her and her Imperial Military Consort, a posting steeped in tradition, having to guide the populace by the hoof every step of the way. This improving situation allowed for either her or the Prince to spend longer periods away from the Chrystal Palace in the far north and come south to Equestria where under the pretense of maintaining strong diplomatic ties with the central Equestrian government they could relax in a kingdom that they didn't have to bother overseeing. It was ironic, then, Cadance mused, that she should be spending her time out here in a primitive wilderness camp about to be pounded by a vicious mountain thunderstorm when she could be sprawled out on a goose down body pillow next to a hot spring-fed pool in any one of several elite Canterlot bathhouses having her every need attended to by beautiful teen mares. However, Cadance knew better than to believe that such an experience would be any better than what she could and indeed did have available to her in the Empire. She didn't go on these trips to be pampered, she had enough of that in her daily routine. She departed the Empire on occasions like this to have an adventure, and in her experience there were few better ways to find adventure than to tag along with one of the most powerful, (unintentionally) wealthy, unnaturally curious, intelligent, and yes- adorably sexy ponies to be found in the world.
Within the circle of tents and covered equipment the gusting winds seemed to loose something of the haunted quality to be found amongst the swaying trees of the darkening forest. With the imminent onset of the first bands of rain Cadance formed a softly glowing force bubble about her body tinted a light blue to match the aura of her horn. Despite the fact the she had performed the creation of a force bubble countless times throughout her life whether just for practice or out of necessity and could do it without thinking as easily as she could place one hoof in front of the other, she could if she concentrated, feel the binding energy somehow adding structure to the air around her. It was almost as if on the point of performing the spell she became aware of an ever present granulation in the air on a scale so small it would be impossible for anypony to see yet she felt nonetheless as though the field was taking thoes loose grains and somehow gluing them together in a rigid structure and expanding that outwards. She had no words to describe the sensation of the process and though she had considered investigating some text on the subject, of which she was sure many could be found in the Imperial Archives, she had never gotten around to uncovering anything conclusive on the matter and yet again reluctantly stored such considerations in her mental category of intriguing thoughts that she ought to ask Twilight about.
Body properly shrouded from the now beating rain, Cadance came crunching down the newly improved path made of stone chips towards the center of the camp. She couldn’t help but notice that a few of the ponies she passed by glancing her way through open tent flaps had slight frowns of worry creasing their faces as they gave small bows of their heads in respect to the Princess of Love. This concerned Cadance slightly, she was quite sure this behavior was due to the fact that many of these ponies probably felt at least some trepidation at seeing an Imperial Princess out in the rain having to shield herself from said rain and not accompanied by any guards. A situation that they were afraid, she was sure, would reflect badly on the conduct of the expedition members if word were to get out. She would have to take the time tomorrow to reassure them that she was very much here of her on volition and that they did not bear any responsibility if her solid gold horseshoes got muddy or her mane, Celestia forbid, got damp. It never failed to worry and exasperate her, at least to some degree, how ponies always seemed to be surprised when royalty acted in any manner other than stuck up and prissy.
As Cadance approached the large tent directly in the center of their little portable village, the right hoof flap of the tent flipped open and immediately out popped the aging yet still spry head of Dr. Oldstone, one of the preeminent researchers of the Royal Academy of Science and Magic.
“Ah! It’s such a relief to see that you’ve gotten back! And just in time it seems!” Dr. Oldstone said looking through the dome of the force bubble as the fat drops of rain pounded down over its glass-like surface.
“We were all afraid that you wouldn’t be able to return in time!”
“I’m sorry for worrying you Professor, I was distracted by the beauty of the countryside on my little hike of the surrounding area and nearly didn't see the storm coming until it was in the valley itself. I’ll make sure to get home sooner next time.” Cadance said with a giggle. This got something of a blush out of the lively old professor.
“Was there something you wished to discuss with me?” Cadance asked while turning to trot under the tent awning and through the open flap.
The “command tent” as it was rather pompously referred to was essentially a large rectangular canvas covered room large enough for around ten ponies to fit comfortably inside staked solidly to the ground with two dozen long steel spikes. This capacity was of course only true if and when the tent was empty, which was certainly not the case at the moment. A third of it was piled to the celling with boxes of research materials including not fewer than a hundred charts by Cadance’s estimation and several times that number of books, mostly still packed away in boxes. Cadance couldn’t help but cringe inwardly at the thought of the ponies who had been given the task of getting all thoes books from the end of the wagon trail twenty kilometers back. The next third was filled with a large wooden table covered with yet more books and charts and from the looks of things professor Oldstone had probably gotten back into his research before the tent itself had been raised up around him.
“Well… truth be told…” he said looking somewhat sheepish, “I had been expecting Princess Twilight to be with you as she is the one who had asked me for some input on a hypothesis or two of hers earlier in the day and I have only just now begun to feel confidant that I can give her good enough answers to her questions.”
“Oh, well I suppose I could go and find her if-” started Cadance.
“Ah, goodness no!” Interjected the old professor. “I wont have you going out to hunt down Princess Twilight just for my sake, and especially not in such weather! Why I should think Celestia would have me thrown out of the Academy is she knew I was imposing myself so!”
“Hardly." Cadance said while mentally rolling her eyes. "Celestia isn’t the sort of mare- princess- to do such things. After all, even Prince Blueblood is still allowed in the castle, well, every once in a while at least…” Cadance trailed off at that realizing she probably wasn’t helping the conversation along anymore.
“Well, regardless, it wouldn’t be proper.” Continued a somewhat more unsure Dr. Oldstone.
“Though since you are here, I might as well fill you in on what the Princess and I were discussing earlier.” The Doctor said with a gleam in his eye that told Cadance he couldn’t resist the opportunity to lecture a new “student” who had so carelessly let herself be drawn into his domain.
“The mystery” he started in, striding over to the large table covered in various maps and pointing to what must have been a representation of the valley they were currently standing in. “Began some 16 years ago when I was doing a survey of early Tribal-Era Unicornia villages and watch posts in this section of the Range to better understand the Unicornia military strategies for defense at the time. This era, nearly six thousand years ago now, is one of the first we have any real record of and was of course immediately after the first alliances the Kingdom of Unicornia had made with the Pegasi state. Though things had gone well for over a century the Unicorns still had not by this point, and really never did I’m sorry to say, get over their fear of the Pegasi.”
At this he gave Cadance an easy to miss sidelong glance; (to judge her reaction she thought) knowing, as did the rest of the civilized world that Cadance had been born a Pegasus.
“Thus,” he continued on, the Unicorns developed a habit of building watch towers and other minor fortifications in the tallest places they could figure out how to inhabit, so that the Pegasi could not so easily get away with any intended sneak attack from high in the air.”
“This is why there are ruins of not one but three watch towers along the edges of this valley, and with these eventually came Unicorn settlements along the valley floor where it was figured there would be a certain degree of safety should any conflict come about.” Early unicorns always were a suspicious lot I must say.” chuckled Dr. Oldstone, his light grey mustache fluttering with his soft laughter.
“This unusually high population left behind an equally unusual selection of ruins for a young enterprising archeologist, such as I once was, to study. Not only were there many sites to investigate but their remoteness meant they were well preserved as there had been nopony around to dig up the soil for farming or haul away ancient cut stone blocks to construct new houses as has happened in may other locations across Equestria.”
“I had already visited this valley twice before the year the mystery was uncovered, most of the time looking at the sites surrounding Mid Lake. It was the year 995 when I arrived in the valley for my third trip.”
“Do you know, Princess Cadance, what occurred here during the autumn of the year prior, 994?” Asked Dr. Oldstone with the expectancy only a lifelong instructor could muster.
“…994? I was still a young teen living in Canterlot back then, I mostly remember that being the year the mushroom farming industry was privatized. And there were some scattered reports of an Earthquake, though I’m not sure if I recall…” Cadance trailed off.
“Oh, Don’t let it bother you Princess, I’m surprised you were aware of it at all, it was a while ago after all and this area of the mountains was even less populated than it is now. Indeed, what occurred was rather a large Earthquake as it so happens! Came as quite a surprise to the geologists at the time I assure you, we had not seen any recent evidence of past earthquakes in the region and had thought there to be no fault lines of any significance nearby.”
“Well, anyway, back to the story!” continued the professor.
When I arrived in the valley in late spring of 995 I was fascinated by the evidence of strong ground movement all about; rock slides, tumbled boulders, and unfortunately some damage to the various stone ruins. More telling though, was the damage left behind by a major flooding event down through the valley. For a while, this river next to our camp may well have carried twenty times as much water as it normally does and if you know what to look for you can still see the evidence from that time all around this area, even though the flood occurred 16 years go now. Therefore, I was not unduly shocked when I traveled further up the valley and found that the entirety of Mid Lake had vanished.”
"Mid Lake?" I didn't see that on the map." Cadance couldn’t help mentioning, despite suspecting the cause.
“Nor would I expect you to, it has still not yet refilled and I do not expect it to either. But let us not get ahead of ourselves now! …Um, Princess.” Dr. Oldstone hastily added.
"Now, Princess, I am assuming you know about Dry Falls, the cliff face that is about three kilometers downstream of High Lake?”
When Cadance nodded in the affirmative the professor continued.
“What one needs to be aware of to be able to understand this situation is that as the name ‘Mid Lake’ would indicate there were once both a ‘High Lake’ and ‘Low Lake’ as well. Low Lake still exists, we passed it on our way up to this place, it is larger by far than either of the other two were and thus, was less affected by the earthquake and subsequent flood. Unlike Low Lake, both Middle and High were created by natural damns of glacial deposits. Great piles of stone pushed into place in front of advancing glaciers and left in place after thoes glaciers melted away. High Lake especially was located far up near the end of this valley between two very steep cliff faces forming the lower sides of a pair of quite tall mountains whose names have been lost to history.”
“It took me some time to pick my way up the valley to the point where I should have been able to see High Lake and as I suspected that lake was not there anymore either. However, I did have my answer. You see, what had happened was that during the earthquake a huge amount of stone and ice had broken off the side of the western mountain nearly a thousand meters above High Lake. When this landslide, weighing perhaps a million tones or more in total impacted the lake it produced a great wave large enough that when it smashed into the damn of piled rock at the end of the lake, it not only flowed over but broke apart the barrier, thus allowing High Lake to drain. This in turn would have sent a torrent of water rushing downstream into Mid Lake where it filled that lake to the point where it too overtopped its natural damn. However, in the case of Mid Lake the erosion of the damn by the draining water was a more controlled event as the outflow channel was gradually widened. This is fortunate, as if all of Mid Lake had drained at once the damage to the valley below would have been considerable.”
“And so this means that…?” Cadance asked, hoping there was indeed going to be a point to this exposition.
“Ah, well you see, with Mid Lake gone I could easily see what had been under that body of water and to my amazement there was not only the foundation of an ancient stone structure that had been previously submerged but below that was a basement level, though this was still mostly full of water. It was determined by myself and several of my associates at the time, that this structure had once been a mill for grinding grain and the basement level was a collection of underground storage rooms. Here is the most important point however; being a mill, it would have been built next to the river at the time of its construction. A river that had not flowed freely in that location due to the presence of the lake and the glacier before that since prior to the time of the last great cooling, a minimum of 40,000 years.
“40,000 years… but that can’t possibly…” continued Cadance uncertainly.
“Rather what we thought ourselves in the Academy at first, but once we had our suspicions we began to look for other evidence in places along where the river would have flowed before the glacier formed. I admit there were times we felt that we were wasting our time and money After all, a glacier had once flowed over the spot, grinding up rocks and destroying any above ground structures. But we were persistent, and now it seems such has paid off. Six years ago after an equal number of years spent digging in lake bottom muck we have begun to find evidence of further habitation. We now have located the foundations of several stone structures along with what appears to be a metal sheet and some hoof tools, preserved in the anoxic environment of the lake bottom.
Cadance’s eyes had widened at this revelation, it was one thing to consider some sort of extremely primitive paleo-pony artifacts from so long ago but evidence of a civilization potentially as advanced as modern Equestria? It was…rather startling to say the least.
“Now I see you are beginning to grasp the magnitude of the mystery we find ourselves in, and why it was decided to conduct extensive research here in these mountains.” Dr. Oldstone said watching Cadance’s expression.”
“But if this is so revolutionary, and I can see that it is, why have I not heard of it before now? I would think such a discovery would be the talk of Canterlot, for a while at least.”
“You see Princess Cadance,” Dr. Oldstone said with a conspiratorial smile. “Now that I have discussed the matter with you that makes you…probably the sixth pony in the world who knows what revelations this valley may hold.”
“Only the sixth! Why the secrecy? Why tell me? …Why the uncertainty in the number?”
“Goodness, haha! One question at time Your Highness. The secrecy is that exceptional claims require exceptional evidence, and we have been working for years to build up that evidence so we don't get immediately run out of the scientific community for being old eggheads that have finally cracked when we go public with our findings here. As to why I told you, well, the circumstances were good you see, you came by here alone during a rather strong storm which would make eavesdropping not only near imposable but very unpleasant for the pony trying to listen in from outside the tent. Furthermore, you are after all, an Alicorn Princess of Equestria -yes I understand you rule in the Empire now but we all know where you were brought up and who assisted in your Ascension. Your loyalty to Equestria is beyond any doubt. Also being a Princess and being on this expedition… well, you don't think I would have blathered all this to some undergraduate assistant do you?” asked Dr. Oldstone full of mirth.
“And if all that were not enough, you are a good friend of Princess Twilight, who happens to be the primary source of funding for this expedition. I felt that you should be fully informed at some point and the sooner the better.”
“Well, it is nice to know that ponies hold me in such high regard, thank you for seeing me as being so trustworthy. Now, if only I could get some of the older Equestrian aristocratic families to think the same…”
“Ha! Well, I apologize but I don't think I would be of much help there, I may have the patience to work on a secretive archeology project for twenty years, but dealing with nobility is another thing entirely!” chuckled the Professor.
“Indeed…well, It has been a pleasure talking with you, professor.” Cadance said inclining her head slightly. Since you mentioned the storm a minute ago I noticed that it seems to have let up a bit, or at least the hail as stopped. Twilight is probably beginning to worry about where I may have gotten off to by now, knowing her.
“Oh, goodness, I hope I haven’t delayed you unnecessarily.” Dr. Oldstone said with a tinge of worry in his voice.
“Hardly” Cadance replied, “Twilight is a grown mare, she can see to herself.” Well, sometimes. Cadance thought, remembering a past event or two. “Don't worry on my account.” Cadance reassured him while turning to leave the tent. “I’m sure we will have more opportunity to discuss matters in the days ahead.”
“Have a good evening Dr. Oldstone.” Cadance said while stepping out into the still heavily falling rain.
“And a good evening to you as well Princess!” the professor said his voice rising to be heard over the noise of the continuing storm as another rumble of thunder rolled through the now open tent flap.
Cadance, again enveloped in her softly glowing force bubble trotted onto the sodden path headed for the rather more ornate and blessedly less cramped tent where she hoped to find a lavender pony to reacquaint herself with.
Twilight Sparkle was feeling a tad nervous. Which, upon consideration, was oddly comforting. After all, she considered that if she didn't feel a little nervous right now she would be concerned for her overall sanity. It all came down to the fact that she badly had to use the bathroom, a situation that was of course hardly unusual by itself. It was something she, like any normal pony, did several times a day without any overt consideration on the matter. However, this time she had suddenly realized that there were options available to her that she had never quite planned on due to events coming together more conveniently than expected. First was the tent. Twilight Sparkle was, despite her inordinately high status in pony society, a mare with very basic wants and needs. Though technically she had been born a noble, it was to a branch of her house so distant and unconnected that the relation they had to any old family money and power was practically nonexistent. That's not to say she had grown up poor, far from it in fact. Her father was the Royal Astronomer, and her mother had been, at least up until Twilight had been born thus making too much of a demand on her time, a schoolteacher. It was simply that none of their money and status had come from family history. Growing up with well-to-do but highly practical parents meant that Twilight normally never considered luxury until it was placed right under her muzzle and sometimes not even then. Therefore, when she had signed on to be an administrator for this expedition she had packed a standard tent and camping supplies and considered the matter dealt with.
Cadance, with the backing of the Crystal Empire however, had had grander plans.
The Empire, upon learning of their ruler’s desire to accompany the Princess of Friendship on a “vacation” to the Unicorn Range had made sure to provide her with not only a luxurious octagonal light green tent with gold trim but a pair of guards/servants as well. Not to mention furnishings of considerable opulence (by camping standards) on the inside. Cadance had mentioned in passing to Twilight that the Empire had wanted to provide her with considerably more than they did, but she was able to talk them out of most of it much to the relief of them both.
It was for this reason that despite all her pre-trip expectations, she found herself standing fully upright in sleeping accommodations superior to that of most inns. There was a central lightweight freestanding aluminum wood burning stove giving off wonderful warmth against the damp high altitude chill of the rainy night outside, a pair of surprisingly comfortable foldout beds with thick patterned blankets and pillows for each, not to mention plush rugs of various colors overlapping each other in a circle around the stove. At the end of one of the beds was where the guard ponies had carefully staked Twilights supplies and various personal items. A stack rather smaller than Cadance’s she noted with a bit of amusement.
This was not to say however, that everything Twilight had brought with her was purely necessary. Thoes things were of course packed well away from anyplace where they could be easily seen in case of carelessness on Twilight’s part. She never worried about the guards; royal guards could never reach such an honored position by being nosy or careless. Twilight started removing the top few bags and cases, thoes with handles on them at any rate, with her teeth. Princess Celestia herself had taught Twilight to not use magic for every little thing that needed doing. It was a sign of laziness and impatience; neither were good qualities to find in a potential future ruler.
Finally, Twilight uncovered and opened her largest chest and began to remove layers of neatly packed and organized items. A pile of woolen stockings, scarves, two parkas and other winter wear came out along with an extra thick blanket, that considering Twilight’s unexpected upgrade in accommodations was unfortunately now rather redundant. It was in the bottom lefthoof side of the chest where Twilight uncovered the source of her nervousness and, honestly, excitement.
The diapers were not something that could be picked up in any corner store, even in Canterlot. Oh, a pony could get such things in such places but the product there was severely lacking in both quality and personality. Not something Twilight considered worth wasting either her time or money on to say nothing of the trouble she would have had to go through to acquire them with nopony else knowing about it. No, that just would not do. It was fortunate for her then that she had connections among the Equestrian population and years ago one of thoes tips on where to get very good diapers, a tip from a pink pony renown for her expert baking skills, had shockingly led in a loop right back into her close circle of friends, to Rarity to be exact. Twilight had to admit though that in hindsight the fact that a pony like Rarity who had her hooves in every form of fashion and outfitting business known to ponykind would at least have heard about ponies with Twilight’s… interests really shouldn't have come as such a surprise.
The Champion of Friendship, High Princess Twilight Sparkle of the Equestrian Nation, the largest and most powerful single country in the world, was rather at a loss over what to do with herself. She gently rubbed her hoof over the stylized form of her loving mentor Princess Celestia that adorned the front of the still folded disposable diaper that her magical field had removed from her trunk and laid on the bed. On one hoof she could simply put the diaper back with the others in the deep recesses of her stacked belongings and go out to use the bathroom like a proper filly and forget that she had even considered…what she was considering. But a part of her, an ever growing part, argued that not only was Princess Cadance one of the most open minded ponies Twilight knew but it was her doing that had got Twilight into diapers in the first place.
Many years ago when she had still been a unicorn filly officially studying under Princess Celestia, she had once complained to Cadance how she hated to interrupt her reading and study sessions just to use the bathroom as she considered anything that came between her and her studies to be a major imposition. Cadance had jokingly suggested that Twilight use diapers to deal with the problem, and somewhat to her shock Twilight had taken her seriously. Perhaps most other fillies wouldn’t have been so keen on the idea but Twilight, young though she was, had spent many days in her own apartment in the castle itself, going home to her parents only at night, and kept as much to herself during her studies as possible. Therefore, the concept that wearing diapers could prove embarrassing never really occurred to her. After all, it was hard to be embarrassed about things when nopony else was ever around to see you do them.
Despite her surprise Cadance didn't take back her suggestion, regardless of having originally made it in jest, but only agreed to acquire diapers for Twilight on the condition that Twilight actually put them to use, thus correcting the situation Twilight had complained of, so that Cadance’s efforts did not go to waste. Sure enough, within a few days Twilight received a rather nondescript package sent from an unfamiliar Canterlot address, and upon opening it found it to contain two dozen thick disposable diapers of just the right size for a filly of Twilight’s age. Twilight had imagined the diapers to be a plain white but these were in fact rather colorful with pink tapes and a wide thick purple plastic area in front for securing those tapes. Cadance had never reveled her source to Twilight, and the Princess of Friendship still was not sure what it had been. It was most certainty not Rarity, as she would have been no older than Twilight at the time.
Putting those diapers on had been an interesting endeavor, not really due to any actual difficulties involved but just because of the unusual though nice way the diapers felt on her. Twilight had up until that point simply considered the diapers to be an answer to a problem but after having put them on, she felt that they might prove enjoyable for their own sake. The temporary distraction caused by the arrival of the package was not enough to keep Twilight from her latest book for long, so true to her promise to Cadance, she let the diaper remain securely fastened around herself after trying it on and settled back down in her favorite reading area. A spot near one of the large bay windows so that she could enjoy the view out over the Celestial Valley and watch the arrivals and departures of the ponies from the palace.
Soon enough, as expected, Twilight felt the desire for relief, and now having a diaper to go in, the resolutely logical filly simply let it all flow out in a strong stream of urine that quickly formed a spreading yellow area that covered the front of the diaper. She watched transfixed as the padding expanded between her legs. Twilight couldn’t help but giggle a bit to herself that this plan was actually working out so well, and also at the surprisingly good and novel feeling of a wet diaper. Now instead of having to get up and distract herself by having to use the bathroom she simply laid back down on her stomach and continued reading. Now even more content than she otherwise would have been thanks to the thick warm wet padding caressing her between her legs and over her rear.
All these memories and more played through Twilight’s head as she came to her decision. Yes, she would wear and even use her diapers around Cadance. It was simply too good of an opportunity to ignore, here she had both a stack of great diapers and a beautiful princess whom she hadn’t been able to spend nearly enough time with lately. If she could truly be herself around her old fillysitter then that would deepen their bond all the more.
With her heart thudding away in her chest both from simple nervousness and from the added stimulation of having to go so bad she felt on the verge of exploding, Twilight unfolded the lusciously thick and well designed diaper and held it tightly against herself while also pulling the green and blue tapes tight in the front. The thick, ever so slightly pink plastic of the diaper reflected the light from the tent’s central wood burning stove, which made it seem to glisten in the dim light. Rarity really had outdone herself with these diapers, the theme and colors were subtle but the quality was more than obvious to Twilight as she simply stood there for a moment enjoying the soft comfort of being a well-padded mare.
Twilight knew she had to hurry though, because at any moment Cadance could come through thoes tent flaps and Twilight would much rather she have had already done her business by that time than be caught in the middle of trying.
With an intake of breath to gather her courage, Twilight let go of her tight hold on her very full bladder and put her fate in the hooves of Faust. Whatever happened after this would happen. Twilight would rather have Cadance not approve of her desires and at least be sure about it than live forever without knowing.
The sudden torrent of pee from Twilight was too much for the diaper to absorb instantly, causing most of it to splash back onto the Alicorn’s sensitive private areas and run down into the front where it temporarily pooled before soaking through into the thick padding, causing the diaper to begin to swell. All Twilight could do was stand there with her eyes closed reveling in the wet heat poring out of he urethra and splashing all over between her legs. Though the way the diaper held onto that wetness and warmth and kept it pressing onto all her most sensitive areas for hours on end was perhaps the best part of wetting.
Though, it would not prove to be the best part overall, if the pressure in Twilight’s rear was any indication. This would be the ultimate test she decided. If Cadance could still enjoy spending time with a filly in a messy diaper, then they truly would have a special bond. So with an act that would seal her fate one way or another Twilight pushed as hard as she could and was instantly rewarded with a hot thick gush of mushy poop that seemed to not stop, and soon filled all the available space in the back of her diaper. The mess was large enough and squishy enough that it began to flow downward and start to cover Twilight’s excited pussy with squishy brown poop.
Trembling from excitement and no small amount of anxiety, she was nearly ready to sit down in it to encourage the complete distribution of her mess, after all, having gone so far why stop now? When a muffled “Welcome back your highness.” Came from just beyond the front of the tent.
Twilight froze, part of her immediately wanted to find someplace to hide to avoid the otherwise inevitable confrontation. The idea was ridiculous of course, where would she go? Leave the tent in her present state? That would be far worse than staying. Another part of her hated herself for getting into this awkward position and briefly considered using magic to preform the world’s quickest diaper change. Though all this went through the alicorn’s mind in less time than it took for her to turn her head she also had time to dismiss thoes actions as only making things worse in the long run. Anything less than her current situation would mean being unable to be true to herself in front of Cadance in a way that seemed a worse fate for her than anything. Cadance was one of the very few ponies that Twilight wanted to be- no, really needed to be, completely open with. It was not healthy for a mare to keep secrets from everypony. There must be somepony who she could confide in. If it went well with Cadance then perhaps Celestia could be…No time for that! Cadance was coming in now.
Twilight turned to face the entrance to the tent as one of the side flaps began to glow blue and move to the side. For a second Twilight could see out into the darkness beyond at the side of one of the royal guards, who, as expected for a true professional, didn't look back in through the opening. Past him, she could see the streaks of the still falling rain. Almost immediately the entrance was filled with the form of the Princess of Love, her flowing pink and yellow mane and tail still somehow in perfect condition despite her day of wandering about the valley. As soon as she laid her eyes on Twilight her expression broke into a warm smile.
“Sorry for not getting back sooner, it turned out there were ponies in this camp who wanted a chance to talk with me, imagine that!” Cadance said with a laugh while trotting right on past Twilight toward her own bed.
“Turns out there is more to this place than meets the eye, though you knew that already of course.” Cadance continued while she pried off her braided gold horseshoes and removed her crown before tossing it aside onto her trunk quite unceremoniously.
Twilight for her part, wasn’t quite sure what to do with herself. Having her diapered condition completely ignored was not one of the possibilities she had given any credence to. As her mind had rather stalled due to the unexpected reaction she simply stood there with a blank smile on her face not sure how to continue. Should she go along with Cadance and simply pretend that nothing was the least bit out of the ordinary? She wasn’t sure how long that would be possible, given the very…pressing sensation of her mess coating her sensitive places. She didn't think that her acting skills, such as they were, would be able to compete with Cadances’ for long.
Cadance, noting Twilight’s lack of response looked up from her regalia which she had been fussing with and met Twilight’s nervous smile with one of such warmth that Twilight immediately began to feel better without Cadance having to utter a word. Cadance turned and walked back and straight up to Twilight and with a foreleg she pushed up on Twilights chin causing their eyes to meet.
“Ladybugs awake?”
“Do- do a little shake?” Came Twilight’s hesitant response. Not quite sure where this was going.
Unexpectedly, Twilight found herself in a tight embrace. How had that happened? The gentle natural smell of the mane of a pony who had spent most of the day out in the forest greeted her nose as her face was buried in the fur of the side of Cadances neck, that, and she was fairly certain there was a hint of perfume, peach perhaps? Then there was another smell, rather different, it…oh, right, her diaper.
Suddenly there was a hoof on her flank, on her diapered flank, and it was slowly moving around in a circle.
“You have absolutely no reason to worry about this Twilight, It’s not like I didn't know after all. In fact, if I’m not mistaken its my fault.” Cadance said while releasing Twilight from her embrace.
“Though judging by the smell you seem to be enjoying them more than I had anticipated.” Cadance said with her characteristic light giggle.
“In all seriousness though, I am very proud of you for working up the courage to be so open about it around me, I had suspected you might have brought some of your diapers on this trip but was not sure if I would get to see you in them. Well, I am very glad that I have.
A rather relieved, though somewhat flustered Twilight stuttered out her thanks for Cadance’s understanding.
“Do you mind if I have a look?” asked Cadance with all the innocence in the world.
“S-sure, go right ahead…” Twilight responded still not fully adjusted to the idea that Cadance really was completely ok with this.
“Don’t be embarrassed Twilight, I’ve encountered ponies with much more…interesting, I suppose I could say, interests than your enjoyment of diapers. Some ponies may not be able to understand your desires, but I am not one of them. In fact, I find it really quite beautiful. Any way that a pony can find to make themselves feel good which isn’t harmful to themselves or others is something to be celebrated. Besides, if you really must know, I’ve worn, and yes- used, diapers myself in the past. You are not the first mare I’ve met who enjoys them after all. Perhaps one of these days I’ll do so again.”
Though Cadance’s admission was somewhat surprising, Twilight noted that it was not as startling as it could have been had it come from some other pony. Twilight could scarcely imagine all the things Cadance had learned as the Princess of Love.
“Wow Twilight, you really have used this thing! Its nicely swollen in front and also in back, though for a different reason I think. And judging by the ah- interesting, customization on the front, that they were designed by a certain pony known in Canterlot for her high-end fashion offerings?”
Twilight blushed at the underhoofed reference to the fact that her diapers were obviously designed with a Princess Celestia theme in mind.
“Yes, actually!” Twilight said, unable to hide her desire to talk about her diapers with a pony like Cadance who understood, well, so many things about her.
“They were made by Rarity. She did such a good job, I really am lucky to have her as a friend!” Twilight couldn’t keep her enthusiasm from bubbling up a bit.
“M-hmm…Thought so…” Came a mumbled reply from Cadance.
Before Twilight could ask what that was supposed to imply, she was startled by the soft press of a hooftip under her tail, which she jerked up instinctively, indicating what her body thought of the sensation before her mind had a chance to counter the reaction.
Again came that soft sweet laughter.
“I’m sorry Twilight, I couldn’t resist, your backside is just too adorable.”
“Ah…thanks, I’m glad you like it.” Twilight replied with a bit of uncertainty due to Cadance’s apparent total lack of concern for the fact that said backside was covered in a well used diaper.
Cadance looked up from her close examination of the thick urine filled padding covering Twilight below her navel and peered into the younger princesses’ eyes with an expression that Twilight honestly had trouble identifying. Something between hopefulness and amusement.
“May I kiss you Twilight?”
Twilight blinked a few times rapidly.
“I...yes?” Twilight eventually said, suddenly realizing that things were going in exactly the direction she has secretly hoped they would. It couldn’t be this easy could it? Perhaps Cadance had known what Twilight had wanted all along?
As soon as Cadance walked back around to be in front of Twilight her soft lips immediately met Twilight’s own and as they both took a step toward each other Cadance’s tongue forced its way between Twilight’s teeth and began exploring the insides of her mouth.
Cadance had definitely known all along, Twilight decided.
“I have a surprise for you.” Cadance said, pulling away from Twilight sooner than she had been expecting.
“Wha-?” Was as much as Twilight could manage, as all she could think about was the lingering taste of Cadance in her mouth.
“I have a surprise for you, come on over here.” Cadance said as she led the violet alicorn around the tent’s central stove and over next to her bed. Cadances’ presence, plus the motion of walking once again, made Twilight keenly aware of the large soft mound of gooey poop filling the back of her diaper and that was sitting right over her sensitive pussy with every motion of her hips squishing it around just a little more.
“I have a feeling you are going to enjoy this Twilight. Now, place your forelegs up on the bed like this… “Good” Cadance said as Twilight complied with Cadance’s prompting.
“Then spread your hind legs a bit. There we go! Now it’s my turn.”
As Twilight was busy trying to figure out what Cadance had in mind, she suddenly found herself being pressed down near to the edge of the bed by Cadances’ weight as the larger Alicorn practically climbed up on top of her, Cadances’ forehooves pressing into the bedding behind and to either side of Twilight’s own. ‘What the-‘ Twilight thought, ‘its almost as if Cadance is mounting me, like a stallion preparing for…’
There was something else. Twilight could see both of Cadance’s front legs, and she must be using both back legs for standing…so then what was pressing into the back and underside of her diaper?
As a soft moan came from Cadance, Twilight, suspicious, bent her neck down as far as it would go to be able to look below herself. And there underneath her, passing between her legs and reaching all the way to the center of her chest was a massive and very hard penis, colored a soft pink that matched its owners’ fur color though there were darker pink patches of skin becoming more prevalent towards the back. Its thickness was pressing strongly against the shiny plastic front of Twilight’s diaper. The sight and feeling of Cadances’ huge member and the squishy mess in her diaper made Twilight feel like her heart rate had doubled and her clitoris suddenly became even more sensitive than it had been before.
Twilight jerked her head back up and stared at the wall of the tent.
“Where…?” Twilight began.
“An Alicorn’s power is very good at hiding what its owner does not wish to have seen. I had to make sure that you were as interested in me tonight as I am in you before revealing myself. I am not in the business of scaring ponies Twilight.” Cadance finished with a laugh.
Twilight couldn’t help herself as she bent her head back down, just feeling Cadance’s massive stallionhood against her diapered crotch wasn’t enough, she wanted to keep on looking at it.
“How long have you been um- excited?“
“Hard?” Added Cadance. “Since I walked in and saw you were wearing thoes lovely diapers, and even more so as soon as I determined you had used them. To be truthful, it wasn’t so much what you did in your diapers that excited me, it was knowing that the only reason you would do so is because it made you excited and that you hoped I would notice and like it. Well, its rather a difficult thing not to notice don't you think?”
“I suppose so…I guess I’m not the best pony at subtlety am I. I also just didn't want to keep secrets from you. I mean, I know you knew that I wore diapers in the past but I didn't think you were aware that I still like to do so, much less use them. So I felt the only way was to come right out with it instead of being awkward about bringing up the topic in conversation. I’m, uh, glad it worked!”
“Oh Twilight, you are such a brave pony, I don’t think you give yourself enough credit in that regard.” Cadance replied while nuzzling the side of Twilight’s neck.
“As enjoyable as this position is...” Cadance said while slowly pushing her shaft forward and back again between Twilight’s legs and against the underside of her diaper. “I think there are ultimately more comfortable ways of continuing.” Cadance removed herself from on top of Twilight, taking that wonderful cock with her. Twilight immediately missed the sensation of having such a large hard shaft pressing into her diaper and immediately looked forward to whatever Cadance had planned next.
“This should do the trick, Glad I thought to bring along a few of these.” Cadance said as she levitated an expertly folded shiny light blue plastic sheet out of her trunk.
Twilight found herself wondering just how many possibilities Cadance had actually come prepared for. Quite a number was the most probable answer she decided. As Cadance unrolled the translucent thick plastic sheet out over her bed Twilight couldn’t help but be mesmerized by Cadance’s now totally unconcealed stallion cock bob around under her belly with every movement she made. At times it even gently slapped against Cadance’s underside whenever the alicorn moved quickly enough. Twilight was technically capable of the magic required to make her own stallionhood but the intended result took a while to successfully grow and everything about it made daily life difficult, at least it had for her. Though she supposed that Cadance probably found the whole experience quite entertaining. Twilight herself was content to remain fully female in all respects, at least for the time being.
“Ok, now we can get somewhere!” Cadance’s cheerful exclamation brought Twilight back to the present with some embarrassment as she realized that she had been doing nothing but pointedly staring at Cadance the whole time she had been preparing the bed.
To her surprise Twilight suddenly found herself in the gentle but firm grip of Cadances’ magical aura as she was bodily picked up off the floor, turned over, and sat down softly on the bed. The effect of which was to squish her poop up the front of her diaper considerably more than it had been, completely coating her pussy under her mess. As Twilight laid herself onto her back reveling in her hot filth Cadance quickly followed Twilight with a hop up onto the foot of the small bed, stallionhood slapping against her chest.
Cadance watched Twilight watching her and smiled warmly.
“This is going to be fun for both of us don't you think, my little pony? Cadance said, not pausing as she stepped over the younger alicorn, lowered her head and taking Twilight’s horn into her mouth.
When sufficiently aroused, a unicorn’s horn can become nearly as sensitive as its owner's reproductive organs. This is why Twilight’s only response to Cadance’s question was a soft moan from somewhere deep in her throat. The feeling of Cadance’s velvety tongue on the hard slick surface of her horn made her shiver with pleasure. Cadance was obviously an expert at this and had, Twilight was sure, performed the same act on who knew how many other mares. With Cadance bobbing her head up and down on Twilight’s horn the young princess almost didn't notice that the tapes on her diaper were being delicately unfastened by finely controlled magic.
Upon recognizing the action Twilight instinctively pressed a hoof up onto Cadance to get her to stop so she could have a chance to understand what was going on.
“Hm?” Cadance asked ceasing her activities. “Oh, no need to worry Twilight, I’m not going to remove your diaper, I’m simply temporarily repositioning it. I’ll tape you back up nice and securely when we are finished.” “Finished with what?” Asked Twilight though she was sure she knew exactly what was going to happen. But it was so big…
"You’re a smart filly Twilight, I think you know exactly what I mean.”
The final two tapes came free with a pop and the front of the thick diaper folded down revealing the entirety of Twilight’s messy crotch and marehood now buried under a thick coating of poop, Cadance sat back onto the bed smiling but holding a foreleg over her nose all the same.
“My, my, Twilight, looks like you enjoy your messy diapers almost as much as…well, perhaps we’ll get to that some other day. I suppose I ought to get used to this if we are going to have any fun tonight shouldn't I.” Cadance said in mock resignation, removing her leg from her nose and taking a deep breath.
“Ahhhh…yes, the smell always does make it... interesting!” Cadance said while coming closer to Twilight with her massive and quite beautiful stallionhood, the tight slick skin of her cock and large balls reflecting the dancing firelight coming through the window of the little stove.
“This isn’t your first time being penetrated by somepony besides myself is it Twilight? Cadance asked though her tone made it obvious she already knew the answer quite well. Cadance made her enquiry while lowering and squishing the head of her cock into the thick brown paste coating the inside of the messy diaper, an action she couldn’t complete without closing her eyes and groaning slightly from the pleasure. She then pressed it up against where she estimated Twilight’s vaginal opening was despite not being able to tell directly due to there being so much poop that it completely obscured the outlines of Twilight’s pussy. Cadance shuddered again from the stimulation as soon as her long thick shaft made contact with Twilight’s entrance. Even for her, a pony that had done quite a number of kinky things it was still an unusual experience. Though not as unusual as some.
“N-no, its not” Twilight replied feeling her face get a little more flushed than it already had been considering the situation.
“I thought so.” Cadance replied with a smile, which was dangerously close to becoming a grin. “Now, Twilight,” Cadance continued while pressing the tip of her rock hard shaft against Twilight’s pussy. “I’m curious, who was your first and what was it like? I need to know. Research you see, I’m sure you understand the importance?”
“But, you already know about that, I told you not long after it happened didn't I?” Replied Twilight.
“Oh yes, I believe you did, but it’s been so long that I need a refresher course. Just the basics, I don’t expect you to remember all the details.”
Though of course Twilight did remember all the details but she wasn’t interested in spending forever on the subject seeing as how it seemed that Cadance wasn’t about to give Twilight what her body so desperately wanted until she was finished.
“I- uh, well Princ- um, Celestia was my first…. she wanted to make sure that I understood how important sex in a pony’s life could be and why it was that it can have such a large impact on why ponies do the things they do. She felt I wouldn’t be able to properly understand the workings of Equestrian society without that knowledge.”
Cadance nodded, smiling. “Of course, how very wise of her, go on.”
“Well it was on a Saturday, in June, so no official classes but like usual I was studying in the Royal Library when Celestia herself came and found me. She took me up to her private bedchambers. I had been there a few times before for late night study sessions but we had never done anything except for cuddling before. Once there she explained to me what my lessons for the night were going to be. I was confused and surprised but also a bit excited, Celestia was so immensely important to me as a filly, I mean she still is but I feel considerably more, well not equal certainly, but somehow more similar to her now than I did back then of course. This was also the first time I ever saw a futa spell in action before. As in, it was the first time I saw a male member or at least its equivalent in its excited state. I was rather scared because even at that age I understood the biological basics if not the emotional results of sex. I knew that the idea was that Celestia’s huge stallionhood was supposed to go inside me and I was pretty sure I wasn’t going to survive the attempt...”
“As it happened though, Celestia had no intention of even trying, she simply wanted to start off by giving me the opportunity to… I guess play with it really. She rubbed it all over me and let me lick the tip. I thought it tasted funny but being a filly I don't think she expected me to immediately love every aspect of it. She also let me rub myself on it. That was the first time I ever came you know, rubbing my um, cunny- is what she called it, up and down her shaft. I remember being shocked it felt so good. That's not to say that she didn't use her natural parts as well. I remember how even though my horn was smaller than it is now she mounted it happily and within only a few minutes she came all over my head and face. Then when she had me suck on her cock again she came with it- all over me from head to hoof. We spent a very long time in the bath being cleaned up afterwards.” Twilight couldn’t keep the smile off her face from the old yet still hot memories.
“These sessions became a weekly thing between us and even though I was never able, and honestly still really can’t, take in Celestia, we never failed to have fun.”
“Thank you for the reminder Twilight, though I believe there is more to tell is there not?” Cadance asked, grinning even more. Twilight was fully aware that Cadance was forcing Twilight to discuss such things for no other reason than because it made both of them even more horny to think about it. Cadance did after all, have a fondness for young love and the thought of a pony such as Celestia herself, usually so regal and conservative in her behavior engaging in sexual play with a sweet young Twilight was exactly the sort of thing that would turn her on, no diaper required.
“Yes, well, when Princess Luna returned, her exile had left her weak and physically…reverted, so that she appeared nearly the same as when she had been a filly, two thousand years ago. Despite her desires, Celestia refrained from having sex with her because she was afraid of worsening Luna’s delicate emotional situation. She was afraid that Luna would feel like she was being used, which was the last thing she wanted under the circumstances. However, Celestia still felt strongly that Luna should have a companion during her recuperation so she enlisted me to help her along. Even though I was living in Ponyville by that time I still regularly made the trip up to Canterlot to see her. Even then, while she was still recovering, Luna always enjoyed being the aggressive one, so I usually found myself on the bottom being rutted like there was no tomorrow. She also has a rather kinky side herself and soon took to wearing latex/pvc catsuits, short shorts, and thongs around whenever she could get away with it, still does last I knew. Luna also loves pee play and taught me how to enjoy being urinated on. I remember the first time Luna peed inside of me during sex. I wanted to be angry at first but it felt so amazing that I let her continue with it and it became our little secret. At least for a while, until Luna regained her full strength after nearly a year and she got back together with Celestia. From what I hear the peeing thing is something they share as well which means that although I failed to appreciate it at the time, Luna was doing me a great honor by treating me like her older sister.”
“Ah yes, the peeing thing…one of Luna’s kinks I love the most...” said Cadance partially to herself.
“What wonderful memories you have Twilight, make sure to treasure them. I know there is more you could tell me but I think you have earned your reward for now.”
As she spoke Cadance began to move her hips forward sliding her thick shaft through Twilight’s squishy poop and began to part the young alicorn’s lower lips. At first the sensations were merely very good but as the full thickness of Cadance’s shaft penetrated Twilight the amount of stretching required of her pelvic muscles along with the immense feeling of fullness made her gasp. It didn't really hurt in any definable way but it had been so long since she had been filled so completely that it was almost like being a virgin again. It was one thing to find a mare to give a hornjob but it was considerably more difficult to find an alicorn when one spent so much time being busy far away from the centers of government as she had been lately.
Twilight also noted through a haze of pleasure that as Cadance’s cock slid in it became coated with her slick scat and this mixed with the clear fluid secreted by her vaginal canal made for the perfect lubrication. Twilight could watch the slight bulge in her stomach migrate upwards the deeper Cadance went, and as Cadance pressed up against her cervix and kept on pressing, Twilight could imagine her internal organs rearranging themselves to accommodate the massive new addition to her insides.
“Ohhhh….fuck….” Twilight breathed as her vagina clamped itself tightly around the huge thing filling it up. “That’s amazing Cadance!”
“I’m glad you like it my little filly. I put considerable effort into making it as perfect as possible.” Cadance said with a soft smile as she slowly drew it back out before sliding it all back in again, this time with a bit more speed and force. Even as far into Twilight as she could get she still couldn’t quite fit all of it inside, though she did come close. Twilight wondered if there wasn’t some sort of magic involved because she was fairly certain that her vaginal canal was not as long as what was currently filling it full. Perhaps her earlier sense of her internal organs moving around had been closer to the truth than she had realized.
Soon Cadance had settled into a slow and gentle rhythm, pulling about two thirds of the way out before sliding back in all the way again. Twilight decided that at this point she was truly, by definition, being fucked. As though doing it with the Princess of Love herself wasn’t just about the best thing ever, the sound of Cadance’s balls squishing in Twilights open messy diaper and the knowledge that with every thrust Cadance was coating Twilight’s insides with more of her own poop made it difficult to not simply give in and come then and there. Twilight did her best to hold out though, so as not to appear too pathetic in front of her lover.
Though she had started out slowly as the minutes went by Cadance relentlessly built up speed. She also began to make cute little noises with each thrust which now only saw her draw back a third of the way before hammering herself back in nearly to her balls. Twilight for her part was fairing no better, in fact, worse may well have been the best description. She had begun to pant some time back and was making even more noise than Cadance. Amidst all the pleasure a small part of her realized that the guards had probably started to be able to hear them some time back. She thought about trying for a sonic insulation spell to put around the tent but decided that if the guards were worth their pay they would have done so themselves before they heard too much of what they shouldn't. Besides, in her present state she didn't feel that trying to induce any sort of controlled magical discharge would be a good idea.
“Are…you going…to cum…inside…me?” Asked Twilight who wasn’t sure how much longer she could hold out for.
“Of course Twilight…that's the best part!…But don't worry you’re…still too young to get…pregnant. If you…were still a unicorn, then…yes of course you could…but as an Alicorn…your physiology is still too…underdeveloped. Cadance replied breathing heavily.
Good thing to be reminded of that, she had been told so before but it was always comforting to learn such was still the case. At this point Cadance’s thrusts were so strong they were pushing Twilight bit by bit across the bed. She hoped this would all be over before she fell off the end.
“Though perhaps someday…” Cadance spoke up “we could have a filly…you and I. That… would be such a... beautiful thing Twilight... and once she gets older… we could teach her all…all about love and sex…and we could have a threesome… Wouldn’t that be such…a wonderful bonding experience…a chance for us to…fuck our own daughter?”
Twilight for her part wasn’t sure how to respond to that, Cadance, in her passion was perhaps beginning to consider things even she wouldn’t normally. Besides, this was not the time or place to contemplate such important matters as how to raise a filly with anything resembling logical thought.
Instead she simply replied with a strangled “I…love…you” as her inner walls began to convulse around Cadance’s thick horsecock.
Luckily that was all the extra stimulation Cadance needed in order to finally cum.
Twilight groaned loudly and arched her back up off the bed as she felt Cadance release thick spurts of hot gooey cum deep inside of her. In fact, she could actually feel it splashing against her cervix. Cadance was now pushing her shaft into Twilight with all her might and moaning while she held onto Twilight’s sides with her forelegs. Twilight could also feel her own clear marecum squirting out from her pussy around the bulk of Cadance’s cock.
After a few more convulsions both ponies slumped back down panting with exertion. Cadance extracted herself from Twilight’s insides and sat back looking fondly at her still long hard stallionhood, which glistened in the firelight. Its light pink skin now coated with a thin coating of slightly brownish fluid. Cadance was sure her member must smell quite awful but it would be hard to tell apart from the more pervasive stench coming from Twilight’s open diaper. Twilight for her part was still laying there breathing heavily and obviously too worn out and numb for another round just yet. Cadance however didn't want to be so patient. After all, so many things in her regular life required constant patience, yet here she sat with a still hard shaft and dripping pussy right behind one of the most willing and beautiful fillies she knew. A bit on the dirty side this pony was, but that just made it all the more fun. She could have about any young mare in the Empire she wanted, on any day she wanted, but it was not such a simple thing to find an Alicorn in a messy diaper to fuck. Besides, Twilight was actually family now, and she loved this sexy little pony on far deeper levels than for just her looks or kinks.
All this thinking made Cadance decide there was no reason to wait. Perhaps Twilight’s vagina was still too sensitive to return to just yet but like any mare Twilight had more than one hole to choose from. With this idea in mind Cadance maneuvered herself back up to Twilight and by lifting the purple Alicorn’s back legs straight up into the air she was rewarded with the sight of Twilights anus, which was of course smeared with a thick coating of Twilight’s sloppy mess.
“What are you…?” began Twilight as Cadance contemplated her next moves.
“Shh…don’t worry Twilight, I know you are going to enjoy this.
Using her magic Cadance scooped up a good sized glob of Twilight’s poop from the inside of her diaper and between her legs. Once collected Cadance began to liberally smear the squishy shit all up and down the length of her shaft paying special attention to its head. The warm goo made the pink Alicorn shiver whenever she spread it around more. Now with the upper two thirds of her cock thoroughly coated she lined up her head with Twilights puckered tail hole and gave a good push.
Twilight groaned and squirmed around some as Cadance pressed forward relentlessly. If it hadn’t been for ponies such as Luna and herself doing this in the past she wouldn’t have bothered trying due to being afraid of causing harm. However, she knew that Twilight’s anus was now stretched enough that this could be made to work, though still with a bit of difficulty.
The hot squishy wetness of Twilights Rectum enveloped the top half of Cadance’s shaft and the lubrication provided by all the smeared poop helped Cadance to more easily work her way in and out of it. Unfortunately, pony anatomy being what it is, there was no way for Twilight’s intestinal tract to fully accommodate a member as large as hers so she had to contend with only a portion being inside Twilight at any given time. This still proved suitable for Cadance to achieve a second orgasm without much trouble however, and she moaned contentedly as more spurts of cum pulsed out of her and into Twilight’s rear.
Twilight watched as Cadance sat back down again having spent herself a second time though in this case inside her butt. Cadance for her part was staring at her still long hard stallionhood, witch was a complete mess as it had been smeared from tip to root in varying amounts of Twilight's waste. As Twilight watched Cadance looked up and met her eyes.
“Twilight, you see my hard dick here?” Cadance asked while rising up onto all fours. “It really is rather a mess don't you think? And that is something that very much needs to be taken care of before I can go to sleep. There are various ways of getting it clean again but I think I have decided on a solution that both of us will find enjoyable.”
Cadance walked right over Twilight who was still lying on her back to give the mare the best possible underside view of her bobbing shaft. Once Cadance had positioned herself over Twilight’s head she lowered herself somewhat so the slick scat coated head of her cock was just brushing Twilight’s lips.
“Ok, Twily open wide, Cadance has a job for you!” Said the pink alicorn in a sing-song voice.
Twilight wasn’t sure that she understood the point of this, even if she could open her mouth wide enough to take in the head, and she wasn’t sure that could be done, her tongue was only so long and there was no way she could clean the whole thing off while just laying there.
Cadance could see the look of hesitation and confusion on Twilight’s face and tried to reassure her.
“Don’t worry about the logistics of it Twilight” Cadance said laughing. “All you have to do is open wide and I’ll take care of the rest.”
Twilight was still hesitant, actually ingesting her own waste was not something she had engaged in in any real fashion. But she dutifully opened her mouth and slid her lips around the end of the head trying to decide if the strong stench was a turn-on or not. It really didn’t seem- All of the sudden Cadance quickly lowered herself down further causing her shaft to quickly open Twilight’s mouth as wide as it would go. As Twilight tried to deal with this new intrusion Cadance managed to position herself so that now the head of her cock was pressed against the top of her throat instead of just against her teeth. Though as soon as Twilight felt the start of her gag reflex coming on Cadance lowered herself all the way down onto Twilight’s face which forced her stallionhood, shaft and all, straight down Twilight’s throat all the way to her stomach.
It really was a strange experience having such a thick hot rod of pony flesh extending all the way down the inside of her neck and into her chest. Her throat muscles rippled around the intruder in a futile attempt to swallow it. Twilight suddenly found herself breathing heavily through her nose as getting air through her mouth proved impossible. She squirmed a bit due to her body’s reaction to something so strange being done to it, but Cadance made soft calming noises at her and explained how to control her breathing.
Twilight had expected Cadance to start fucking her throat quite quickly but Cadance, being the considerate mare that she was, was content to simply lie still on top of Twilight and let the poor pony get used to the situation before Cadance began to add motion to the equation. This lull in activity also provided Twilight a lengthy chance to taste Cadance. Her own waste was of course the first taste that she experimented with as her tongue was pressed flat against the side of Cadance’s shaft. In all honesty it wasn’t a very good taste, somewhat bitter to be truthful, but oddly she did enjoy the gooey almost velvety texture. Below that though, was Cadance’s stallionhood itself, which was slightly salty from perspiration.
Cadance soon interrupted Twilight’s education on the various flavors of sex as she finally began to pump her shaft up and down the length of Twilight’s esophagus. The Princess of Friendship was surprised at how quickly she became adjusted to what was in all respects a highly unusual thing to be doing with one's body, but Cadance slid herself up and down Twilight’s throat with a full steady, oddly comforting rhythm. Even with her mouth open wide and her head bent back she was able to calm her breathing and be able to enjoy the extra pleasure of having Cadance’s large full shiny balls press themselves up against her face every time Cadance bottomed out. Twilight was sure that whenever Cadance pushed in as far as she could get that the head of her shaft was actually entering her stomach. Twilight worked on repeatedly trying to swallow, this worked her throat muscles in a way that hopefully would give Cadance some extra stimulation. It was a tequnique taught to her by Luna years ago but it was not something she had been given an opportunity to practice in quite awhile.
For some time Twilight simply lay there underneath the larger princess, relaxed and content as Cadance expertly pumped herself up and down the length of Twilight’s slick throat, every now and again making soft noises of pleasure and twisting herself this way and that. Though as expected after a while Cadance began to slowly increase her rate of speed and no longer pulled out quite as far before plunging back in. Twilight for her part simply let herself be taken. This was Cadance’s way of cleaning herself off of the mess left over on her shaft from fucking such a dirty little mare and it was only right that Twilight help the process along as best she could.
It wasn’t long before Twilight felt the telltale convulsions running down the length of Cadance’s shaft and sure enough, a second later she could feel thick ropes of sticky cum burst out and splatter around inside her stomach and lower throat, a feeling that Twilight hoped would never get old. Cadance, now frantic with her motions, groaned and pumped as hard as she could, causing her balls to repeatedly slap Twilight on her nose. With a final sigh Cadance began to pull herself up and out, but to Twilight’s confusion she stopped with the last few inches of her shaft still down Twilight’s throat. If Twilight could have, she would have asked what the delay was for, but having a mouth full of Cadance made that rather impossible. Instead she contented herself with waiting to see what would happen next. She didn't have to wait for long.
Suddenly Twilight felt a hot burst of liquid explode into her throat and pour down her esophagus. At first she thought Cadance was cumming again but it didn't feel the same, the flow was much more consistent and it felt like drinking… Suddenly Twilight realized with a start that Cadance was peeing inside her. And not just a trickle either but a full on strong pissing that seemed to go on forever. The hot liquid warmed her throat and chest and made her body feel more relaxed, much like drinking hot tea. It didn't taste of anything as it was flowing out of Cadance’s head well below her tongue. In many ways it was an extremely sensual thing to experience even if at least on her part it lacked the hot eroticism of direct sexual stimulation.
After having so much urine pumped down her throat by a still hard Cadance that Twilight actually began to feel full, the flow reduced to a trickle and Cadance finally removed herself completely from Twilight.
“So Twilight…what did you think of that? I hope you enjoyed my cleaning process, I know I did.”
“It was wonderful, thank you Cadance…at least I don’t feel thirsty anymore!” Twilight replied while rubbing her belly.
“Hehe, you are so very welcome little filly.” Cadance said as she bent down to give Twilight a quick kiss.
“However, I believe that as you were so wonderful with helping me out I am obliged to return the favor. Also we need to do something with this open messy diaper you are laying on. Would you like me to change you… or just simply tape you back up in it?”
Twilight considered for a moment, a fresh diaper did sound nice in a way but that also sounded like a bit of a waste as she had only really been wearing the first diaper for a few minutes before Cadance had untapped it.
“I um, would actually like to stay in this one if you don’t mind…I don’t want Rarity’s work to go to waste…” Twilight said blushing slightly
“Oh, I don’t mind at all, I love my little messy filly and as long as she enjoys her messy diapers I will love her for it!”
“Though first,” Cadance continued, “I have a use for this diaper which I think you will enjoy.” As she said this she squatted down over Twilight so that her crotch hung directly over Twilight’s shit smeared marehood which was still leaking cum out into her diaper. Twilight couldn’t help but notice that as Cadance arranged herself that her once massive cock and balls had shrunk considerably and were melding into her crotch almost like she was a pond and they were slowly sinking beneath the surface. Within a few minutes they would be gone as if they had never been. Twilight couldn’t help but admire the magical expertise involved in Cadance’s version of a futa spell. There were a number of ways a mare could give herself temporary male parts but many were crude and/or only partially functional. Cadance’s was, rather unsurprisingly, about the best Twilight had ever seen.
As soon as Cadance had positioned herself properly she stared right into Twilight’s eyes and smiled. Movement caught her eye and Twilight watched transfixed as a thick gooey rope of poop pushed out of Cadance’s butt and plopped down right on top of Twilight’s pussy. This was immediately followed by another hot thick mass and then a third, both even larger than the first. The color was lighter than Twilight’s and the texture a bit more firm, solid enough to somewhat keep its shape but easily soft enough to be smeared around if desired. Its wet heat on Twilights clit made the mare squirm and moan.
“I thought you might enjoy that.” Cadance said as she used her magic to expertly fold the diaper up and over the huge pile of her waste that had completely buried Twilight’s marehood. As she taped the diaper into place there was so now much poop that the diaper bulged out even more in front. All Twilight could do was close her eyes and groan. There was so much hot sticky mess in her diaper and it felt so good to wiggle her hips from side to side and feel the load shift around and mix with her own mess between her pussy lips. The thought that this hot mess has just, moments before, been inside Cadance’s body was enough to make Twilight sure she was about to cum all over again.
She had once thought Pinkie Pie to be the dirtiest mare she knew of but here she was being pleasured by something as equally depraved. The idea of having her pussy deeply buried in her fillysitter’s poop being squished about in a well used diaper made Twilight so horny that it only took a minute or two of Cadance rubbing and pressing down on the diaper between her legs to make the young alicorn squirt out hot mare cum. The clear fluid being mixed into the mass of Cadance’s scat filling her diaper.
As Twilight lay there, upside down on the bed panting and once again tightly taped up in her now far more messy diaper, Cadance lay down next to her and with a brief glow from her horn pulled a cozy blanket over the two of them and extinguished the lanterns hanging around the parameter of the canvas tent. This left only the flickering firelight from the stove for illumination.
“That was a great thing to do for both of us I think.” Cadance said as Twilight rolled onto her side and shuffled backward into Cadance allowing their bodies to mold into each other. “The fewer barriers between friends and lovers the better. Now we both know how far we are willing to go with each other and it will save us a lot of awkwardness in the future. And I think that that is exactly what you were hoping would happen. After all, I see no other reason why you would be wearing a messy diaper before I even got back to the tent. You are more intelligent about love then you give yourself credit for Twilight.”
“Aw, thanks Cadance, that means a lot from you. And thank you for the um, well the diaper thing, and the throat thing, and well, all of it really…”
“My pleasure Twilight” Cadance replied as she brought a foreleg over the younger alicorn to gently rub the bulging front of Twilight’s diaper, pressing it into the mass of poop so huge that it was nearly threatening to squish out the top.
“You’re the best toilet that anypony could ever ask for.”
Twilight awoke slowly and in the best way possible. Not only did she have Princess Cadance snoozing contentedly, her larger body spooning with Twilight’s own. Even better, the Alicorn must have regenerated her amazing stallionhood sometime during the night, and Twilight could feel its thick length pressing up against her diapered butt. Ah yes, the diaper itself. That was the single best part, Twilight thought sleepily. It was so wonderfully full, with the warm slimy poop of two alicorns mixed together by their love for each other and spread all the way from the base of her tail around to near the top of the front of her diaper. Even the slightest movement of her body brought fourth pleasure as her wet pussy was squished about under the deep layer of soft poop. By now her marehood must be coated by at least two centimeters of the stuff, Twilight estimated.
She became increasingly aware however, of precisely what it was that had brought her out of her wonderful deep sleep. She desperately needed to pee. Twilight was not normally a pony that had to get up in the middle of the night for any reason, bathroom trips included, but having had the Princess of Love pump what had seemed to be a liter of urine down her throat the previous night, was a sure way to make her have to pee more often than usual.
Twilight decided to roll over onto her back because she was not sure if her already bloated diaper could contain a large pee so well if she were laying on her side. It might all decide to leak out of one leg hole or something she worried. Despite slowly and quietly reorienting herself, being cuddled by Cadance meant having to adjust her as well, somewhat unsurprisingly this resulted in Cadance waking up despite Twilight’s best efforts. At first Twilight was not sure if Cadance’s mumbling was the result of her waking or just a bit of sleep talk. But the sudden presence of a hoof rubbing the front of Twilight’s diaper along with a soft;
“Something the matter, princess?”
Thus informing her that Cadance was very much aware of the situation.
“No, no problems. I just uh,”
“Need to pee?” Finished Cadance.
“How’d you guess?” Asked Twilight drily.
“Oh, I just seem to have a sixth sense about these things.” Cadance said, continuing the light banter as she stood fully upright on the bed and looked straight down at Twilight’s already swollen diaper.
“If you intend to wet again, I would love to get a better view, I believe right about…here, should do.” The Alicorn said while lowering herself so that her muzzle pressed gently into the thick, smooth plastic of the diaper. Right, as it so happened, above where Twilight’s pussy lay. Warm, soft, and comfortable under it’s thick layer of mess.
Twilight only smiled at the light sarcasm, and spread her hind legs, now sticking up into the air, slightly father apart allowing for Cadance’s head to better fit. Twilight finally, gratefully, relaxed her hold on a now somewhat painfully full bladder and began to wet herself.
The hot urine, at first trapped under the thick poop pooled right over her pussy making Twilight squirm with the pleasure of the warm liquid bubbling over her already sensitive lips. In only seconds however, the pressure of her flow forced its way through and combined with the the already slick mess in her diaper to create a goopy flow which quickly found its way to the back of the diaper, an area that had not had the chance to become particularly wet from the previous night’s only major wetting, though it was damp from all the mush poop spread around that area.
Cadance, with her experience in such matters took this time to use her magic to levitate Twilight’s butt up off the bed so that the warm goopy mess would be able to properly pool underneath the young Alicorn’s shapely behind. Twilight, for her part simply closed her eyes and let her bladder do its job, filling her already full diaper with what was in essence, she considered, another mare’s urine, despite it coming from her own body. It all felt so wonderfully warm, hot even, as the diaper swelled even further and the light pink plastic became even more discolored by the now very brown looking padding material underneath.
Eventually, Twilight felt her flow coming to and end, and so did Cadance, thanks to her sensitive ears. Thus, just as the last trickles of warm pee were dripping out of her shit smeared pussy, Cadance let Twilight’s diapered butt back down gently but firmly onto the blue plastic sheet protecting the bed. The effect was an audible ‘squish’ as Twilight’s weight forced the deep pool of liquid poop that had formed in the seat of the diaper to be pressed upward in all directions, liberally coating almost every part of herself protected under the diaper’s warm embrace with runny, brown scat.
Twilight groaned in ecstasy as Cadance laughed softly watching as the diapered alicorn laying before her squished her diapered butt back and forth trying all she could to maximize the wonderful feeling of the warm, slimy, extremely smelly mess coat every last part of her that she could manage. The diaper was wide enough and messy enough that she even managed to get the upper part of her cutie marks a bit dirty.
“Oh Twilight, you know I can’t let you do something that sexy on my own bed and right in front of me without knowing what the consequences are going to be.” Cadance said standing back up and spreading her back legs slightly, showing off her huge, long, glistening phallus, pre-cum dripping from its head, and heavy balls.
“As good as last night felt, I bet the feeling will be even better this time, as the, uh, consistency of the- of our, mess has had time to improve.”
“Please Cadance,” Twilight started, turning her head to the side from embarrassment, “Please fuck me, please fuck me in my messy diaper… I…”
“Shhh…” Cadance said gently and calmly.
“I know what you want. You want my sticky cum and our slimy shit to mix with love and passion deep inside of you. You want it all to stay in your body and make you feel good for the whole day.”
As Cadance spoke and Twilight blushed to the point that she was sure the older pony could see it through her fur, Cadance was busy at work untaping the tightly secured diaper. As each tape came loose with a ‘pop’ Cadance’s concentration seemed to grow less on Twilight as a pony and fixated completely at the shit smeared treasure lurking between the strong back legs of this gorgeous mare.
The layer of mess over Twilight’s pussy was actually rather less thick than it had been when the well padded mare had gone to sleep hours previously. The heavy wetting recently completed had allowed much of it to be redistributed elsewhere in the diaper. That's not to say the folds of her entrance were immediately obvious, there was still a lot of scat, and even using the head of her cock to wipe some to the side, Twilight’s lips were so coated in brown that not a single bit of the normally light pink skin showed through.
Despite knowing that Twilight was easily wet enough on her own to provide the necessary lubrication, Cadance couldn’t keep from lowering herself down so that most of her long shaft was pressed down onto Twilight’s now open diaper, smearing it in stinky brown muck. Cadance groaned at the feeling and decided then and there that she would look into getting back into diaper play when first she had the opportunity to get in touch with Rarity again.
With phallus now properly lubricated, Cadance lined herself up with Twilight, and drove herself straight in as far as she could go.
The sudden intensity of being fucked so quickly and fully made Twilight gasp, her legs trying to squeeze together around Cadance’s waist. Cadance, for her part, was in absolute bliss. She could so obviously feel the slimy coating of scat that slickened the insides of Twilight’s vaginal tract and used it to fuck the mare all the more quickly without worry over injury. Her deep hard thrusts into the willing alicorn making them both gasp and moan. Adding to the joy was doing so over Twilight’s open diaper, allowing Cadance’s balls to slide back and forth through the slick poop, which only served to heightened her pleasure.
“Please…Cum in me…Cadance…please...” Twilight gasped as she felt Cadance’s thrusts grow deeper and more powerful, a sure sign that the Princess of Love was about to live up to her title, all over Twilight’s insides.
“Uuuhhhh….” Was Cadance’s only comment as hot, thick cum erupted out of her, and deep into Twilight, making the mare in turn reach her peak squirting what would normally be clear marecum, now tinted brown, out around the thick base of Cadance’s still deeply buried shaft.
Not even bothering to remover herself, the still quite horny Cadance- was it the pervasive stench of the messy diaper that excited her so? Began, unceremoniously, to plow herself back into Twilight with enough force to lift the smaller Alicorn’s backside completely up off the bed. So again the two went back at it for several more minutes until yet again, Cadance practically exploded into Twilight with enough cum that it too began to squish out around the base of her shaft. Cadance was reminded that there was something tremendously sexy about fucking a mare who she had already came in and feeling all that cum from the previous ejaculation squishing around her dick.
