"Lovesick" was one of the early working titles

The scent had already been strong, but as the train rolled to a stop at Ponyville station, it became nearly overwhelming. Cadance couldn't keep herself from sneezing, and neither could the train's engineer—both of them were overcome with a brief sneezing fit, and Cadance heard the train's firepony doing the same from the coal tender. Only a minute after arriving, and already the tainted air around Ponyville had begun to affect them.

And tainted was the air indeed, though it certainly didn't smell like anything was necessarily wrong; in fact, the air smelled absolutely wonderful. It was sweet and thick with vapors from all sources, flowers and ponies and animals alike, like some sort of perfume that was layered on cloyingly thick. While Cadance wiped her eyes and nose with a spare kerchief offered by the engineer, she looked out over the town, and understood now the sheer scale of the calamity.

Ponyville was nearly smothered under a thick haze of pink mist. It had been so consuming, coming down the tracks from Canterlot, that she nearly couldn't see the village; only Twilight's Crystal Castle had emerged from the haze, like a lighthouse in the late afternoon fog. According to the letters that Spike had sent from the edge of the area—he'd been giving a lesson at the Ponyville schoolhouse, with Cheerilee's assistance—it had been spreading slowly over the course of the day, and they had to keep moving further and further away from town in order to keep the haze from affecting the foals. Cadance left Canterlot as quickly as she could, and she still regretted that she hadn't arrived sooner.

Apparently, the fog inhibited teleportation as well, which meant from here she'd need to move forward on hoof and wing. While she could have flown directly here from Canterlot, she had agreed it was better to save her strength—and from what she had been told, apparently flying under the effects of the fog was...difficult. Though not for any magical reason.

Speaking of those effects—they were already beginning to afflict her. Her body felt warm, especially between her legs, and her nipples had started to get oversensitive, chafing against her bra in a way that was almost painful. And she wasn't alone; whatever minor effects she was feeling, the train's engineer and firepony were getting the full brunt of the magical aphrodisiac. She looked back at them, and she could nearly see hearts in their eyes when they looked at her.

“Pr-Princess Cadance,” The engineer was a thin, mustached stallion, and he'd been rigidly professional about the train's operation and the time it would take for them to reach Ponyville, but now he acted more like a horny teenage colt. “You're...you're so....ahem. Is there, ah, anything else we can do to serve you?”

He adjusted his trousers, with his erection clearly straining against the fabric, and Cadance gave him a warm smile as the firepony panted in the coal tender a few leg-lengths away. Better to to help them out now, and make sure the locomotive was properly shut down, plus she could put her theoretical spell-work to practice now. “I do believe there is. Why don't you quench the boiler, and when you're done, I'll give you both a reward for getting me here so quickly?”

The engineer spun on his hooves so quickly that he nearly tripped, and the locomotive started venting steam a moment later once he opened the vent and dumped the pressure. As he did, the stallion who had been shoveling coal from the tender hopped over the side to join her on the locomotive car, where he started undoing his belt right in front of the Princess of Love.

And Cadance was just as eager; there was a worry in the back of her mind, as she helped pull his pants down, that maybe she wasn't as resistant as she thought. But she ran through her plan and what she knew of the situation, and felt confident in her ability to push forward...after blowing off some steam of her own.

The stallion's cock bounced up out of his pants and onto her muzzle, and Cadance eagerly wrapped her lips over the length in a moment. He had been shoveling coal just moments before, and Cadance felt his sweat and heady musk roll over her face as she breathed it in deeply. His fingers still left streaks of coal dust in her mane and across the fur of her face as he pushed her further down his cock, but she didn't mind. After all, she was going to be a lot more filthy by the end of the day.

The engineer emerged from the cabin just as Cadance's chin bumped against the firepony's balls, and he didn't seem to mind that the firepony had gotten Cadance’s services first. He quickly began to strip off his own trousers, leaving his vest on, and soon Cadance was swapping between sucking both cocks as she knelt on the train car, still fully clothed. She kept going for another minute, making sure both of them were well-lubed, and then she pulled off the firepony's cock. “Mmmm…you should sit down.”

The firepony nodded and sat back on the rider's bench at the back of the locomotive engine, while Cadance turned her attention to the engineer. This time, as she sucked his cock down into her throat, one of her hands slid up his inner thigh, and she slipped a finger into his rear while she played with his balls. The older stallion let out a startled moan of pleasure, and a spurt of pre-cum, which Cadance rolled around on her tongue as she pulled her lips away from his dick once again. “Why don’t you take a seat as well?”

She gave him a gentle push backwards, onto the firepony's lap, and the engineer seemed startled again as he felt the other stallion's cock press against the hole that Cadance had been fingering just a moment ago. The firepony seemed surprised as well, but took it in stride, and he wrapped his strong hands around the hips of the more-delicate engineer, before gently guiding him down.

While the engineer groaned, Cadance's mouth returned to his cock, and she started to suck him off as the firepony's cock slowly invaded his ass. It only took a few seconds for him to slowly bottom out, and Cadance took the time to lavish both sets of balls at once, as they laid atop each other. Then the firepony gently began to bounce the engineer on his lap, slowly enough that Cadance could follow the rhythm as she knelt between their legs, and her horn began to glow as she prepared her spell-work.

From what she'd been told—and what she could clearly see from personal experience—the fog kicked the sexual instincts of living creatures into overdrive, effectively acting both as performance enhancer and aphrodisiac. A pony so drugged could fuck a dozen times in a day with only a short break to cool down between each round, and each load would be a magnificent orgasm in both volume and pleasure. But it was partly an illusion; the pony's body was being deluded into thinking they could keep going, and suppressed their exhaustion. All Cadance had to do was use her own powers over love to suspend the magic's effect on the victim for a few moments, and let that exhaustion roll back in to overwhelm them.

And it was easiest to do that immediately after an orgasm, which should safely knock out an afflicted pony for a while, even if they were still suffused in the fog afterwards. So Cadance took the engineer's cock all the way down the the base again, deepthroating his length as the firepony gently thrusted into his ass, and as she felt his muscles tense up, she let out a moan that reverberated through his lower body, so that the firepony could feel it too.

“Ah—ahh!” The engineer let out a panting moan as his cock flared in her throat, and the firepony sped up, then slammed him against his lap one final time as they both came. The firepony was hilted deep in the engineer's ass as his length flared against the smaller stallion's prostate, and the engineer continued to come as Cadance pulled off his cock. One spurt went right down her throat, another filled her mouth, and two more splattered across the Princess of Love's white button-up blouse, staining it and turning patches of the cloth transparent, revealing her bra underneath.

With the two stallions panting before her, Cadance's horn flashed, and both of them smiled as they started to get sleepy, already tired from just this first round of sex. While they weren't likely to be napping for more than an hour, that was more than enough for Cadance to prove that her spell worked. She stood up, and kissed them both goodbye as they slipped into unconsciousness, cuddling each other, with the firepony still hilted inside the engineer sitting on his lap. “Sleep well, both of you.”

With two of them safe and snoozing, Cadance turned her attention to the rest of the town. She wouldn't have time to fuck everypony who was drunk on magical lust—she had to handle the problem at the source.

Cadance stepped off the train and onto the platform, and took stock of what little equipment she had. She was casually clothed for travel—she'd been wearing something more formal when Spike's letter interrupted that annoying bureaucratic summit, and she couldn't have changed clothes faster when Celestia read the contents. Speaking of Celestia, the elder princess had given her a set of three crystals for emergency communication, which were meant to be broken in order to relay a message remotely. Green indicated the problem was solved and the royal guard could move in to assist, blue meant that Cadance couldn't solve the problem and was returning to Canterlot, and red meant that Cadance was in immediate danger, and needed a prompt rescue. Simple, and Cadance had used the system before.

Luna had given her a sword. Which Cadance had expected, because that was Luna for you. Not that she didn't appreciate the gift, but Cadance very much doubted that it would be of much use here. She’d yet to even remove it from its sheath, but she still kept it attached to her belt—just in case she was wrong about the source of the affliction.

No, this was a problem much more suited to her own skills, and her own assets were already quite sufficient for that. Cadance cupped her clothed breasts, still wet as the cum soaked through her blouse, and still heavy with milk from her pregnancy with Flurry Heart. She gave them a few bounces to make sure they were still hefty and tittilating—there was no reason she couldn't have a little fun of her own, after all.

* * *

While she walked through Ponyville, Cadance tried not to get too distracted, but that was admittedly difficult. Everywhere she looked, the residents of the town were naked and rutting like wild animals, just on the street. Ponies having sex on tables, in doorways, out of windows, anywhere one could imagine, in any position, in any combination.

She only paused when a familiar voice called her name from the doorway of Sugarcube Corner. “Ooh! Cadance! Funny meeting you here!”

Cadance smiled at Pinkie Pie in greeting as she stepped into the bakery, and bit her lip as she looked around. “I like what you’ve done with the place, Pinkie.”

At least, it had been a bakery before; now it seemed more like a food-themed brothel, with ponies fucking on tables, in booths, and with Carrot Cake bent over the counter, getting pegged by his wonderfully plump wife, while another stallion rammed Cup Cake’s hips forward into her husband from behind.

Pinkie Pie herself was everywhere at once, fingering Roseluck, who was laying on her back on a table, then bouncing over to Caramel, who was seated on a stool at the counter. She bounced her fat ass on his dick for a few seconds, before she dismounted and rolled over the counter to drop onto her knees, and lap at Carrot Cake’s balls briefly. She was still wearing her baking apron, and only her baking apron, which completely failed to hide her pregnancy—not that it seemed to slow her down in the slightest, as she rapidly served customers all over the shop.

Her lips separated from Carrot Cake’s balls with a wet ‘pop,’ and she hopped up onto the counter to take a seat, where her legs wrapped around Caramel’s shoulders. “Aww, thankya! Though honestly we didn’t have to do much, that sweet pink fog did most of the work, and a lot of ponies just decided to come here for refreshments all on their own! It’d be great business for us, if more ponies were still wearing pants and carrying bits.” Her giggles pitched upwards a bit as she pushed Caramel’s muzzle under her belly, so he could see to her while she talked to Cadance.

“Speaking of that pink fog, did you happen to see where it—ah!”

Cadance’s question caught in her throat as a feminine pair of hands suddenly groped her breasts from behind, pressing the soggy fabric of her shirt against her bra. Another pair of tits pressed against her back, and she recognized the voice of Ponyville’s mayor. “Princess Mi Amore Cadenza! I wasn’t told that you would be visiting town, or else I would have put together a…welcoming ceremony.”

Cadance gasped as Mayor Marigold quickly started to unbutton her blouse from behind. “Ahh, I appreciate the thought, but really, it’s not necessary. I’m here about the fog, I’m pretty sure I know where it’s coming from, and I’m going to fix it—”

“Oh no, really, I insist! We’ll just have to…improvise.” The mayor moaned over her shoulder while she pulled Cadance’s shirt open, then yanked her bra downwards, exposing the alicorn’s hefty breasts to the rest of ponies inside the bakery. She was still wearing more clothes than anypony else inside the building, but Cadance had a feeling that was about to change—not that she was really fighting to stop any of this.

Marigold pulled Cadance’s arms back as though she was about to cuff her, but instead pulled her opened blouse back down along her arms, fully exposing Cadance’s chest and shoulders, while also trapping her arms behind her body. “Big Mac! Perfect, why don’t you help me see to our royal guest?”

Another pair of hands replaced Marigold’s, and the mayor slipped around to Cadance’s front. From there, she slid her hands behind Cadance’s back to unclasp her bra entirely, which she tossed away into a random corner of the bakery. Then she began working her fingers down to the princess’ waist, to work on loosening her belt. Behind her, Big Mac was already naked, and Cadance could feel his hard length pressing up against her rump through the fabric of her pants as he pushed in closer, getting ready to mount her right here, in the doorway of Sugarcube Corner.

Pinkie just kept talking, as though they weren’t both having sex while they continued the conversation. “Oh, you know where the fog is coming from? That’s great, we should probably do something about that, huh? Should I go get the other girls?”

“That’s probably not necessary, Pinkie, but it’s a good thought. I’m—ah!—pretty sure Twilight’s involved directly, but do you know where the others are, in case we need the elements?” Marigold grasped the waistline of Cadance’s pants, and the weight of Luna’s gifted sword on her belt helped her pull them down to the princess’ knees, followed by Cadance’s lingerie panties. She didn’t remove either article entirely, because keeping them around Cadance’s legs meant she couldn’t leave without tripping over them, effectively forcing Cadance to stay put.

Pinkie absent-mindedly bucked her hips against Caramel’s muzzle while tapping her chin in contemplation. “Well, Rarity looked like she was getting some great dick in town square, last time I went out there to bring her and all her new ‘clients’ some water. I think Discord is keeping Fluttershy busy in her cottage, so I had to leave the cupcakes and milk on their doorstep. Dashie is still flying even though it’s apparently really hard considering how horny she is, but she pops in every once in a while to drop off an exhausted partner and grab a replacement, then she hauls them off to a rooftop somewhere.”

Big Mac grunted as he thrust inside Cadance’s cunt from behind—even though she was sopping wet, it was a tight fit, and Cadance let out a gasp as he sunk deep inside, then started thrusting. As he did, he leaned forward over her shoulder to join the conversation. “AJ’s busy with some timber wolves. Reckon she’ll have ‘em all trained as guard dogs by the time ah get back.”

“Aww, that’d be good! Hopefully she doesn’t get any splinters in her coochie, I know that’s no fun!” Pinkie leaned back and loosened her legs, and Caramel gasped for breath as he was released, with his muzzle absolutely soaked in Pinkie’s cum. He collapsed back onto the floor, and Pinkie hopped off the counter, then stepped over him as she pulled Mayor Mare into a tight hug, with only her apron between the two otherwise-naked mares. “You said Twi was probably involved?”

With Pinkie now distracting Mayor Mare, Cadance could focus a bit more on Big Mac—mostly on the feeling of his cock drilling her insides, and the warmth of her arousal as it dripped down her legs. But she readied her spell nonetheless, because she couldn’t afford to stay here all day, as much as she wanted Big Mac to keep her pinned against the doorway and fuck her brains out in front of the whole bakery. “Mmf, yeah, she—mm!—she had a guest visiting her castle today, and Shining and I—ah!—were both supposed to be there.”

Pinkie’s eyes lit up, as she kissed Marigold, and slipped a few fingers into the older mare’s lower lips. After a moment, she broke the kiss, and grinned in excitement as she asked, “A guest, huh? Anypony I know?”

“You could say that,” Cadance said, panting. Big Mac pulled her arms up as he started to get close already, forcing Cadance’s torso down, and she found her face being pushed into Pinkie’s mammary mounds. She started kissing and playfully nipping at the breasts before her, and Pinkie giggled as she pushed a nipple into Cadance’s mouth. To her surprise, milk squirted across her tongue; she must have had Pinkie’s pregnancy to thank for that. Though she’d tasted her own a few times, this was her first time drinking another mare’s milk, and she sucked at Pinkie’s tit greedily for more.

After a few moments, Big Mac let out a pleasured grunt, and Cadance lost her grip on Pinkie’s nipple as she felt herself getting filled with hot cum. It washed down their legs and stained her panties, and she swore she felt her belly swell with just a single massive load from the stud. She gasped as milk ran down her chin, and Marigold gasped as she watched, while Pinkie continued to finger her.

After the overwhelming pleasure faded, Cadance flashed her horn, and Big Mac’s grip on her arms loosened as he staggered back. His cock popped free from her nethers with a second wave of cum, and Cadance pulled one arm out of her blouse before she used her other hand to flick the piece of clothing onto the counter. With her arms free, she helped Big Mac steady himself, and she guided him down onto a chair inside Sugarcube Corner.

He was a big stallion, with much greater endurance than even most earth ponies—her spell wasn’t nearly as effective on him as it would be on anypony else, because he simply wasn’t exhausted yet. That seemed to be a fact that Pinkie was extremely eager to capitalize on; she pulled Mayor Mare towards Big Mac, and they both sat on his lap on either side of his shaft, while she continued to kiss and finger the other mare.

That meant they were both distracted, and Cadance used the opportunity to escape, starting with pulling her totally-soaked panties back up to her hips, even as she felt cum gush out into the fabric and ooze down her legs again. Her pants weren’t much better; a huge stain ran down the inner legs. Cadance considered whether she should just leave all her clothes here, since they were all wet with sweat and cum already—and she had no idea where her bra had landed—but she didn’t want to linger too long. She settled for leaving her blouse, and she’d just continue on topless. She was all the more tempted to leave behind the heavy sword hanging from her hip but she knew Luna would admonish her for it.

“Pinkie,” Cadance called back over her shoulder, “when you’re done there, can you get a search party together? Just to make sure everypony’s okay, so they can sleep all this off. Bring lots of water, everypony’s gonna be dangerously dehydrated after all this.”

“Sure thing, Cadance!” Pinkie said with a smile while she and Mayor Mare started jerking off Big Mac at the same time. He was a big stallion, and it was easy enough for them to both wrap a hand around his cock, while they continued to play with each other.

That was enough for Cadance; even though now she was walking a bit funny, she stepped back out onto the street, and continued onward towards Twilight’s castle, which wasn’t much more than a blurry shape in the pink fog.

* * *

Cadance was almost disappointed that the castle had been left unguarded, without even a pair of sentries to watch the front door. Lack of security aside, it would have been fun to “earn” her passage into the castle. Instead, Cadance pushed the double doors open and strode inside, topless and unashamed, as she began to search through the aberrant structure.

She had never much liked Twilight's Crystal Castle. The material was familiar to her, but the Empire didn't shift like this tower did. True, it meant that when she was in her empire, she spent a lot more time climbing stairs than she would have liked, and the durability of crystal meant that boring a hole for an elevator wasn't really feasible. And yet, at least she could memorize the halls of her demesne, without the unsettling feeling that the building itself was watching her, and enjoyed playing little pranks on the inhabitants.

Such as walking out onto a balcony that overlooked Ponyville, then when she turned around, the hallway from which she'd emerged had changed into a classroom, and when she stepped out of that room, finding herself in a circular loop of hallways that only ended when she doubled back on herself, ending in a lavish bathroom. She stepped through the door on the other side of that bathroom, and into the grand hall where the Friendship map and the roots of the Golden Oaks hung from the ceiling, and then when she left that room, she found herself in a guest bedroom, which connected through a door—which seemed as though it would lead into another bathroom—to a grand library, instead.

That path also eliminated several locations where Cadance had thought she'd find her quarry; maybe that was the castle's intent, to save her some time in the most confusing manner possible.

Throughout it all, the pink haze that suffused the air only grew more dense. And she couldn't remember the castle having decorative planters in the halls before; maybe some of Twilight's friends, or the residents of Ponyville, had brought them in as gifts. But now, the well-trimmed flowers and bushes that were meant to add visual variety to the crystal halls were quickly outgrowing their beds. Vines crept up the walls and across the ceiling, strangling the light fixtures and dimming the light from the windows with walls of leaves. Flowers of every variety bloomed and flexed as Cadance watched, and she could actually see them wheezing pollen into the air to fertilize each other. Even the dead roots of the Golden Oaks didn't seem so dead anymore, and they had begun to wrap around the supports of the ceiling, better anchoring itself high above the map table.

The devotees were the next sign that Cadance was getting closer. Ponyville had seemed relatively quiet, and this was why; a significant portion of the village's population had gotten inside, where the haze was strongest, so they could rut naked with wild abandon in the crystal halls. They had been joined by the students of Twilight's friendship college, who were made of a wide variety of species across the world, and all had equally fallen prey to the lustful haze that overtook the town.

So they could get closer to her, the source of all this lustful madness. So they could carnally worship her.

Until they reached a point where even the erotic floral haze that filled the air had not been enough to keep them from exhaustion. Now, they laid snoring in the halls and hallways of Twilight's Crystal Castle, and Cadance had to step between them—or often over them—to continue forwards. A few of those who were more lucid gazed groggily at her, maybe not even recognizing who she was, only that she was still barely dressed.

If they could still move without their whole body growing sore from overexertion, Cadance wondered, would they try to stop her? Either because they might surmise why she was there, to put an end to this erotic madness...or maybe just to rip her clothes off her body and take her, here and now. The idea of getting ravaged by a proper crowd of lust-drugged Ponyville residents aroused her interests, and Cadance filed the idea away for later—she still had work to do.

She needed to keep a better eye on her balance; more than once, she stepped into a slick patch of sweat, cum, or a mixture of both, and those were treacherous on bare crystal. The first time it happened, it took her completely by surprise, and she counted herself lucky that she'd landed on the milky breasts of a well-endowed mare, who blearily groaned in her sleep as she inadvertently cushioned Cadance's fall. After that, quick reflexes and forcing her gaze away from the exhausted array of naked revelers around her kept her from taking a second embarrassing tumble into the cum-splattered mass of bodies—not that anyone here seemed awake enough to see it.

As the piles of sexually exhausted sapients of every species, shape, and body type stacked up higher, Cadance soon found herself in front of a grand set of double doors, inlaid with a symbol all too familiar to her. Not Twilight's cutie mark, as one might expect in her crystal castle, but her cutie mark instead. She stepped over a colt in his late teenage years, who was still buried in the muff of a much more adult mare as they both slept, and braced herself against the handles of the doors. She pushed them open delicately, in case she dislodged anypony leaning against them on the other side, or in case anypony had decided to sleep between the door and the wall, then slipped through into the room beyond.

This room, she knew, had not existed before this day. It was a radical departure from the rest of the castle's design, and Twilight's own preference for aesthetics, which tended towards the compact, warm, but well-lit halls of a library. Had the castle been ordered to create this room, or had it simply chosen to accommodate the new ruler with a throne that suited her? Whose side was the living building on, anyway?

For it was a throne room—at least partially in appearance, if not in function. The sheer size of the room easily rivaled that of Celestia and Luna's combined throne room in Canterlot, and the back half was raised, like the dais of a temple, so that the one who sat on it could look down on her supplicants as they worshiped her from below. The whole room was dimly lit; there was none of the crystal lighting in here. Instead, lighting was provided by two long rows of braziers that ran up the stairs to the throne, burning with gentle pink flame that did little to dispel the smoky, erotic gloom of the throne room. While the room had windows along one side, the glass from which they were formed had been so darkly tinted that only the faintest natural light from the setting sun was allowed to illuminate the scene within.

And what a scene it was. Cadance looked over the aftermath of a record-breaking orgy, where piles of horny, bleary sapients of every race and gender were stacked in piles up to her shoulders, three high and absolutely covering the crystal floor in a layer of sweat and horny fuck-flesh. Cum ran between the breasts and tiles of the room like rain ran through gutters, and the few who hadn’t fallen unconscious lapped at the salty moisture for what little hydration they thought they could reclaim.

Cadance looked over all of this, and felt a genuine pang of regret that she'd missed the party.

“Another devotee enters my chambers?” A voice came from the throne above—a voice Cadance recognized, for it was her own. Younger, more exuberant, and with an odd dramatic flair—but undoubtedly her own. “Come, I invite you. Ascend the stairs, so that I may behold your beauty, like those who came before.”

Cadance stepped around and over the piles of snoring sapients, and even had to climb over one brown-furred pegasus mare at the bottom of the stairs—she checked to make sure she was still breathing, just in case she'd fallen down the stairs and broken her neck, but she seemed fine—and carefully climbed up into the light of the braziers, around the gleaming puddles of sweat that made them so dangerous, to meet her dead ringer face to face for the very first time.

And she was indeed a nearly perfect doppelganger of Princess Mi Amore Cadenza. Her breasts weren't as full, and her hips weren't quite as shapely; Cadance hadn't realized just how much she'd filled out when she became pregnant with Flurry, but even just this little glimpse of her younger self brought back memories of her own prior exploits. Back from before she became an alicorn, perhaps; this younger version of herself shared her natural pegasus wings, but her horn was a totally magical creation, glowing brightly and ethereally over her brow, and her fingertips were glowing with unrestricted magical power.

She laid on her side, in a seductive and evocative pose on what Cadance had thought to be a throne at first, but now that she could see it up close, realized that it was more than that. The crystal castle seemed to have created a piece of furniture that was a throne, an altar, and a lavish bed all at once. It would have been comfortably large enough to fit Celestia and a harem of a dozen amidst its cushions, while the object of their affection was being worshiped by their lust-drunk followers below.

She wasn't the only copy; behind her, a pair of Twilight Sparkles—one an older, taller alicorn princess, and the other a shorter, younger copy wearing an adorably dorky pair of glasses—were kissing each other as they were lovingly pounded from behind by a pair of Shining Armors—again, one older and more experienced, and one who was younger, and his body less hardened by time and training. They moaned into each other's mouths, as their inter-dimensional siblings rutted them with wild abandon, under the loving gaze of Cadance's body double. This time—for Cadance was sure they had been trading off all day—the siblings were currently pounding each other's sister with wild abandon.

The five of them had kept fucking long after the orgy below had subsided, and Cadance had to guess that it was because of her doppelganger's magic. Even now, she could see waves of pink haze rolling off her naked body like shimmering waves of heat—both types—and it rolled down the stairs like a heavy fog. The whole room was filled with that haze, illuminated by the magical pink fire in the braziers, and they were breathing it all in directly from the source.

Long after their bodies should have surrendered to exhaustion and sleep, they had just kept going, and the five of them were soaked with sweat and plastered with cum, which leaked from the pussy and asshole of both Twilights and the other Cadance. She even thought that perhaps their stomachs were a bit larger than they should have been—all the cum packed into them by their many lovers here and below must have filled them past capacity long ago. Even both Shining Armors looked as though they'd taken turns on each other's asses, as dried cum had run down their legs, leaving trails of flattened fur as evidence.

“Well, then! This is a pleasant surprise indeed!” The other Cadance smirked at her like a predator readying to pounce, as she plucked a glass of floral wine from the floor beside the altar. A milky swirl of cum had splashed into the bowl of the glass, or maybe she had asked one of her many partners to contribute a load to the flavor—either way, Cadance sipped the mix of cum and wine without even a second thought, and swirled the remainder seductively. “I was led to understand you were too busy to welcome me to Equestria?”

“I was,” Cadance nodded, her eyes drawn to the pairs of siblings fucking noisily just beside her double. “I had been asked to stay in Canterlot for some diplomatic crap, but I dropped that in a moment when we received Spike's letter, and I came as quickly as I could.”

“That you have,” said the doppelganger, who motioned towards Cadance's cum-stained pants—with even more still dripping down her inner thighs. “And I invite you to do so again, Princess. Or perhaps, after today, I should be the Princess, and you the Dean?”

“Kinky; roleplaying is always fun, especially with the right outfits.” Cadance stepped closer, while she finally undid her belt and began to discard the last of her clothing. The sheathed sword fall to the floor with a gentle thump, which attracted the attention of the Sparkle siblings. She wouldn't need it, she was more confident than ever, now that she had met the other Cadance. Her dampened pants and underwear followed it, and both Cadances were now fully nude, wearing only the cum of their respective conquests.

“Ohhh, I like you,” Dean Cadance said with an eager smile. “Boys? Why don't you give your sisters a break, and greet our guest properly, so we can both warm up?”

The two Shinings looked at each other, then the younger held up his hand in a high-five, which the older met with his own hand. Then they slid out of the respective Twilight Sparkle they had been fucking, and gave them an affectionate slap on the rump as their attentions were focused on the newcomer instead. Both Twilights gasped in exhilaration, and they collapsed onto the bed together, like puppets whose strings had been cut. Even then, they didn't stop having sex; they just focused their attention onto each other, kissing and groping each other in a tired sort of delirium as they lay alongside each other.

The two Shinings smirked as they walked around either side of the bed/altar/throne, and Cadance took a seat as they approached, watching as their cocks bobbed with every step. The twin shafts were slick and stained with a cocktail of cum, mare juices, musky lube, and whatever wine and potions they'd slathered across their dicks, and as they reached her, she took each one in a hand, and started to lick and suck at both in turn.

As she slurped them both clean, or as close as they could get without a proper shower, she revealed the flesh underneath. Immediately, she started to worry about how long they'd both been drugged, and how much their senses were being dulled by the magic. Underneath the erotically filthy mixture that had painted their lengths, the flesh looked sore and puffy, even reddened by overuse. It was a testament to her husband's strength and his younger doppelganger's stamina that both were still walking, magical haze of lust be damned. Cadance hoped that she could exhaust them both quickly—assuming that they weren't already dry-firing without being aware of it.

Cadance shifted so she was on her hands and knees atop the bed, and smiled up at the younger version of her husband. “I think I'd like you in my throat. My Shining? Your choice of holes.”

Her Shining braced himself on the bed as his cock pressed against her rump, and Cadance let him get settled as he pushed into her cunt, before she took the alternate Shining back into her mouth. Maybe in another situation, they would have started slow, but they'd been rutting any hole they could reach for unimaginable hours now, and had no patience left for warming up. Both thrust inside her in a moment, and Cadance was pressed between their hips as both cocks slid inwards to the hilt without much difficulty, since she was still leaking cum from the load the guard outside had pumped into her.

The alternate Shining gasped as her snout pushed up against his belly, and her tongue slipped out to lap at his balls while she deepthroated him. Meanwhile, her husband grabbed her wide, motherly hips hard enough to leave dark red marks on her flesh, and started to pound away at her. Cadance let him set the rhythm, and she let that rhythm bob her head for her, along the length of the younger Shining's cock. Her nose filled with a familiar musk, but different in some way that was hard to place. She knew Shining's scent by heart, and this was so close to that familiarity.

After a few moments, the alternate Shining hesitantly ran his fingers through her mane, and found the coal streaks that had been left by her first lover today. They smeared as his own hand gripped her mane like that firepony had, and he began to thrust into her, bucking into her face while his older twin humped her from behind.

The other Cadance was clearly enjoying the show; she already had her own glowing fingers pressed into her cunt, as she laid back against the two Twilights, who split their attention away from each other to focus instead on their mistress. Each one shifted to either side of the alternate Cadance. The older Twilight pulled her into a sloppy kiss, while the younger Twilight's hand joined the other Cadance's own, to help finger-bang her dean.

Meanwhile, Princess Cadance was starting to get tired of holding herself up, and she moaned into her younger lover's dick—which he certainly enjoyed, but he didn't seem to get the message, as he kept vigorously fucking her face. She had to slap at his thigh before he got the message, and let her up for air, which she greedily sucked down. She was still being forced against his hips by the force of her husband railing her from behind, but as she bounced on his balls, she managed to gasp out, “I—ah!—I want you in me, too! Shining, pull me up and switch holes, so I can bounce on both of you!”

Her husband roughly grabbed her shoulders in his broad hands, and Cadance relished in how strong and how large his hands were, after years of military training and defense of Equestria. He didn't even struggle with her weight as he pulled her up, and shifted his weight so that he was now sitting on the bed, with Cadance's back against his chest. Her wings were still flared out, and he had to shift his grip under them to grab under her arms, and haul her upwards one more time.

Cadance very nearly regretted it, as she felt her husband's cock slip out of her slit and leave her gaping, but as she came down with her anus pressed tightly against the tip of his dick, she bit her lip. She drew a drop of blood as he invaded her anus—the first such invader today, since Big Macintosh had chosen to use her cunt for his pleasure instead. And the younger Shining did the same, after sliding in underneath her and pushing his own tip upwards to fill the void left by his older copy.

Cadance gasped as both Shinings started to rut both her holes at once—she'd had fantasies about this, and she relished them all the more now that they were becoming real. The strength and experience of her husband as he bounced her on his lap, compared against the younger exuberance of his younger self, before his body was hardened by the Equestrian army, was a sublime juxtaposition. She let out a lust-filled groan as she pulled the younger Shining closer, and between her motherly breasts—hopefully a preview of his own later life, and his own later wife. Both their broad chests were pressing against her, and Cadance felt like the filling in a sandwich as she was jostled between them, with both of her holes buzzing hot with pleasure.

On the other side of the bed, the alternate Cadance had relinquished her pussy to both Twilights, who were taking turns pressing their fingers deep inside her lips as she lazed back with a blissful expression on her face. Even that wasn't enough for the two purple mares, and the older one pushed forward to begin suckling at one of the other Cadance's nipples—which the other Twilight noticed, and started to do as they continued to finger-fuck her. From the noises the fledgling lust-goddess was making, it worked very well, and she squirmed on the bed as her own orgasm seemed imminent.

But Princess Cadance beat her to it, and as her gasps and moans reached a fever pitch, the other Cadance sat up to see it for herself, and even the two Twilights paused to watch the show. Cadance bounced on the cocks of the twin stallions faster and faster, heat erupting deep within herself, and both the stallions let out the same pleasured groan that she loved so much as they started to pump their last loads for the day inside the Princess of Love.

They only began to slow down after the threesome's orgasms had all subsided, and Cadance's horn flashed as she lovingly withdrew her younger twin's influence over their bodies. The long work of the day overcame them in seconds, and both stallions were asleep before they hit the bed. They both fell back onto the cushions, peeling away from Cadance like the petals of a flower unfolding, and she was the only one of the three to remain upright.

She let out another pleasured groan as she felt both the cocks hilted within her start to soften, and she turned her lustful gaze onto her doppelganger. “All warmed up, now?”

There was a flash of hesitation—perhaps Dean Cadance realized, for the first time, that she was way out of her sexual depth—but it passed in a second, and she seductively beckoned the Princess towards her with a flick of her hand. “Attend to me, Princess. I can't let you have all the fun, now can I?”

“Of course not,” Princess Cadance said, smiling warmly in the afterglow. “Love is most powerful when shared—as I'm sure you've learned today.”

Dean Cadance spread her legs for Princess Cadance, and both Twilights shifted to make room as they continued to suckle erotically at her breasts. “Indeed I have. You know this power well, but you can't let it flow outwards like I can, embracing everyone in my lust.”

Princess Cadance let her talk, as she slid between her doppelganger's thighs. Her own idle fingering, and the vigorous fingering that both the Twilights had given her, had started to loosen up the loads she'd taken throughout the day. As Cadance dragged her tongue over those vertical lips, a thick bead of cum lazily oozed out, and she eagerly sucked it into her own mouth. Was this from Shining? Which one? Or was this pumped deep within her womb by another sapient in the room? It'd be amusing if Dean Cadance took a liking to gryphon or minotaur dick during this little adventure.

“Ahh...imagine it: this haze, covering Equestria, and the lands beyond. No war, no fighting, only primal urges of lust and love. And once I've enthralled this world, then I'll bring this magic back to my world, until both worlds come together in every way...”

Princess Cadance didn't have to work hard as she buried her muzzle into a pussy that she knew well, though she'd never seen it from this angle before. She could see both Twilights above still working feverishly on her doppelganger's breasts, squeezing and groping them for milk that wouldn't be produced quite yet, and the younger Twilight had moved her kisses up alongside the other Cadance's throat, while her hand continued to pinch and tweak at that nipple. Together, the three of them worked to tease Dean Cadance to an orgasm, and it kept the lustful megalomaniac distracted, as Cadance charged her horn once more.

“I'll take your title for my own...improve it, even! Princess of Love is so limiting in scope, not when this power can bring even the strongest to their knees...I'll make everyone bend to my will, and I'll watch them all make love, for my amusement, and for—ah!—our pleasure...”

Cadance pushed her tongue deep into her doppelganger's folds, and enjoyed how her voice changed pitch, just for a moment. Cum rolled out in steady dribbles, staining the fur of her muzzle a lighter shade of pink. It was all working, and Dean Cadance began to squeeze her thighs together around Princess Cadance, holding her tighter as she rapidly approached her orgasm.

“Mmmph! You're so good at that, you and your husband, and both Twilights...and I love how well-endowed all your stallions are...I'm going to keep you five all to myself, as members of my personal harem! Yes, you'll get to watch at my side as my husbands fuck more children into the four of us, and we conquer both worlds—!”

Dean Cadance was panting as she spoke, and her orgasm came hard, spurred on not only by the ministrations of her new pets but by the thought of her imminent victory. She reveled in the dreams of using her power, and the grand orgies that would be in her future as she took both worlds within her loving bosom. She only stopped speaking as the pleasure overcame her, and it was replaced by a high, groaning whine that Princess Cadance hadn't heard since her teenage years.

And then Princess Cadance's spell hit Dean Cadance, at the height of her orgasm, and her power began to back-flow into her. The feeling was totally alien, as all the lust she'd spread across the Ponyville valley started to draw back into her body in the span of moments, and the high of her orgasm was drawn out in turn. She felt as though her orgasm was drawn out like time had stopped, and that moment stretched on for longer than any living creature could have been prepared. Her mind flashed with lightning as her magical horn exploded into glittering ethereal fireworks, and her fingertips dimmed as the power that had overcome her was wrested back under control.

Dean Cadance slumped back as the world began to slip away from around her, but the last thing she saw and heard was Princess Cadance, with her own wings spread wide, horn burning with magic, and her lips and fingertips wet with her own juices, reflecting the last light from the sunset. “I know this power better than you could ever imagine. I feel it flowing through me every day. And I know how to keep it under control.”

And then all went dark, as post-orgasm exhaustion slammed into her like a tidal wave.

Princess Cadance made sure her twin was safely unconscious, before she smiled at both Twilights. “Thanks for the help, you two.” She gave them both a kiss on the lips, then pulled both sleeping Shinings to the center of the bed to join them. With one last glimmer of magic, she reached back to her discarded belt, withdrew the signal crystals, and cracked the green one. Secure in the knowledge that the other two Princesses could handle the cleanup from here, she joined the others in dozing off together, in a pile of sweaty, slick, post-sexual bliss.

* * *

Everything was sore. All the way down to her bones.

Dean Cadance let out a pained groan and shifted in her sleep, and instantly came to regret the movement as it sent fresh shudders of pain through her body. That worked pretty well to wake her up, and as her eyes blearily slid open, she tried to rub at her face.

That was odd. Her face felt...wrong.

She blinked, and looked at her hand, in case her hand was wrong instead...and it was, though not in the way she expected. Instead of pink flesh, her hand was covered in a short, trimmed layer of fur, like an animal. And her fingernails were much too thick, like tiny hooves that capped her fingertips.

“Aww, looks like somepony's awake!” Her own voice said, though her lips hadn't moved. And the voice was a little too deep, a little too...husky, she wanted to say. More mature. A moment later, there was suddenly pressure around her head, as someone leaned down over her, and a large pair of unclothed breasts pressed down around her ears.

She glanced down, and realized she was naked as well, and lying in a lounging position on a plush chair. And her...fur? She had fur? Was a mess, stained with what looked like a horny locker room's worth of cum and sweat, dried and matted across her body.

Slowly, it all started to come back to her, and she wanted to hide in those pillowy breasts around her head. “Oh...so that...that wasn't a dream, then...”

“A dream come true for a lot of sapients, I'd imagine.” The other Cadance—Princess Cadance, the one who was supposed to be in this dimension—stood up straight, and walked around to her front, where she took a seat in a chair across from her. Dean Cadance (it was so strange to think of herself in those terms) looked around the room, and realized she was sitting in a lavish bedroom, where the walls, floors, ceiling, and most of the furniture was crafted from impossibly-carved translucent crystal. A crystal centered in the ceiling provided light, and as her gaze drifted beyond the other Cadance, she saw an open balcony door that allowed in fresh air, and a view of the night sky.

“So,” the other Cadance took her hand in her own, gently and supportively, and gave her a squeeze that reminded her just how sore all of her muscles were. “How much do you remember?”

A flurry of images flashed across Dean Cadance's mind, and she clenched her eyes shut as her whole body felt sore again. “Uh...most of it, I think. I...oh god.”

The other Cadance laughed, a tinkling laugh that reminded Dean Cadance of her mother. “It's okay. All things considered, everypony had a pretty good time, even if we all woke up sore and dehydrated. Speaking of, you should drink this.” She passed over a glass bottle that reminded Dean Cadance of a potion in one of those fantasy RPGs that Shining loved so much, sealed with a cork. The other Cadance's horn—she had a horn on her forehead, and that startled her more than it should have—glowed blue, and the bottle uncorked itself before her eyes.

This was too much. Dean Cadance just focused on swigging down the clear liquid in the bottle—and to her surprise, it was just water. It was clean, pure water, like it had just been bottled from a Swiss mountain spring a minute ago, and it was the most delicious water she had ever tasted in her life, but it was just plain water. She still drank the whole bottle, as she suddenly realized just how thirsty she was.

The other Cadance kept smiling, and patted her hand. “I've got three more of those here whenever you feel ready. Dehydration is no joke!”

“Please,” Dean Cadance groaned, and a second bottle replaced the first in moments.

The other Cadance waited until she was nearly finished with the second bottle, before she spoke again. “Now then, we should talk about fertility spells.”

In an instant, all of the water in her mouth escaped into her lungs, and Dean Cadance started coughing in shock, while her counterpart laughed again. Evil! She was evil! “W-what do you mean?”

“Mostly,”—that comforting hand returned to her own—“so that you don't have to worry about it. From what Twilight tells me, contraceptives are somewhat of an inconvenience on the other side of the portal, but here, we have several spells for various stages that can handle cleanup as ponies desire. And a lot of the town's unicorns and the unicorn division of the royal guard are going to have their hands full with casting, I can assure you! But I also suspect a lot of couples are going to go without, because you did genuinely make a lot of ponies very, very happy with only an afternoon's work.”

“Th...that's good,” Dean Cadance mumbled. Then her eyes flicked down to her own belly. “...Um.”

Princess Cadance patted her hand again, and answered the unasked question. “Yeah, probably. Both of us, in fact, though we won't know for sure for a few weeks. Again, it's up to you, but I have it on good authority that you'll make a great mother.”

Dean Cadance swallowed. Her throat was still dry; this was a lot to take in all at once. “Wha-what happened, exactly?”

“Oh, that!” Princess Cadance sat back in her chair, and wisps of magic danced from her horn to her fingertips. “We're still not quite sure? Twilight and Celestia think that it was something about your body reacting to the magic on this side of the portal, like my fate was entangled with yours, or the ambient magic tried to restore the powers that it thought you should have? It's all very strange, especially since it didn't happen with Twilight—your Twilight, that is.”

Speaking of... “She...her and Shining? Both of them, are they...angry at me?”

“Not in the slightest,” Princess Cadance said comfortingly. “Like I said, you made a lot of ponies very happy today. And stranger things happen all the time here in Equestria—Ponyville's really got a track record, from what Twilight tells me. No, once everypony had a good rest and a bottle of water, things were fine.”

But they weren't here. Dean Cadance glanced around the bedroom again, and asked, “Where...?”

Princess Cadance gave her a warm smile. “Well, after they showered, my Twilight went off to show your Twilight the castle's expansive library—I suspect we'll have to tie them both up just to get breakfast into them in a few hours. As for the Shinings...I think they're both still in the shower.”

“Both?” Dean Cadance felt like her mouth was full of cotton. “At...the same time...?”

“Apparently your Shining hasn't had a lot of experience with other stallions, from what he told me. My husband's always been willing to experiment, though, so yup, showering together, though they're probably just saying it's because of some big tough stallion military habit where they clean each other's backs.” Princess Cadance waved her hand dismissively, then reached down to offer it to dean Cadance. “Wanna go join them?”

Dean Cadance felt grimy, stained with sweat, cum, and all manner of other unmentionable fluid remnants from her flirting with the power of love. A shower sounded like a great idea...but a shower where two Shining Armors and another Cadance sounded like a fantastic way to get cleaned off...or maybe to get dirty again.

Author's Note

This one went through a bit of revision, but all for the better; Cadance's mention of fucking her way through guards at the front door was in reference to a now-deleted scene where she did exactly that, but they were unnamed and my pre-readers suggested putting more focus on Ponyville instead, which was the right call.

Strangely enough, there seems to be a notable lack of Princess/Dean Cadance porn or shipping, and the same goes for the two Shining Armors, though the two Twilights are common enough. This particular six-some seems to be totally untapped territory, and I was delighted when it came to mind, especially the mental image of the penultimate scene inside Dean Cadance's temple of lust. If I ever get fanart of this story, I'd definitely want it to be about that room, and Cadance's bed/throne/altar.

On another note, if you enjoyed the vivid descriptions, scene-setting, and world-building of my specific style within this story, I'd be remiss not to recommend The Hollow Pony, my Dark Souls/MLP crossover. This story was originally going to be in that same vein, as a Dark Souls porn parody, before I decided to diverge from that concept entirely and focus on the raw eroticism of this concept by itself.

The song for this chapter is: Des Rocs - Dead Ringer (for what I should hope is an obvious reason, plus the vibe of the song fits very nicely.)

Big thanks, as always, to my pre-readers Non Uberis, Prince-Nightfire93, and Citizen for all their hard work!

I've also got a tip jar, if you're enjoying the story and want to toss me a couple bucks!
