Fluttershy encounters a strange, ancient idol that looks just like her... and contact with it awakens her body in strange and wonderful ways.

When Daring Do finds a fertility idol in an ancient temple, she makes an unexpected discovery... the busty, curvaceous statuette is the spitting image of Fluttershy, a friend of Daring's biggest fan.

Only it's not quite identical; the statue, unlike Fluttershy, has an enormous penis. Daring Do takes the idol to Fluttershy's cottage, looking for answers, but only manages to fluster and embarrass the prudish pegasus.

But coming in contact with the idol triggers a change in Fluttershy. Her mind and body are awakening, and who can say just what she'll become as she's overcome with lust, beauty, and size?

Contains: Futa, growth, hyper orgasm, solo.

Chapter 1

Daring Do leaned back against the crumbling stone wall and massaged her shoulder. Truth be told, the fingers doing the massaging were just as sore as her shoulder, but there wasn't much she could do about that. Her sore-all-over body would just have to hold out a little longer.

As she twisted her upper body, the bauble on her necklace bumped against her cleavage. She still hadn't gotten in the habit of using the little voice-recording charm - a ball of wax wrapped in enchanted copper wire - but she figured now was as good a time as any to give an update.

“I've just gotten done hacking away the overgrown vines that locked the entrance to the… to what should be the central chamber. Architecture suggests that this temple predates Nightmare Moon by a couple centuries at least… iconography is unfamiliar but nothing too out of the ordinary… I'm looking forward to seeing what Celestia has to say about my pictures once I submit them for review.”

She paused and let out a short, breathless chortle. “A thought just occurred to me - imagine how difficult archaeology would be in a world where there weren't any millennia-old alicorns to consult. You'd find an artifact, and you'd be like, wow, I wonder what this was for! Too bad everyone who knows is dead!”

She pushed off the wall and stepped towards the door she'd cleared of vines. “Well, anyway,” she said, “this place is badly overgrown, but mercifully free of guardians or traps. Hopefully the central chamber is no different - and if it is guarded, the next thing you'll hear will be an off-the-cuff quip about snakes or something.”

She pushed aside the stone slab that had sealed the chamber, and she beheld a room of modest size - but decidedly immodest decoration. Daring Do had taken note of some… erotically charged murals on the way here, but she'd reserved judgment on whether this might be some sort of fertility temple. That wasn’t usually the sort of conclusion you came to mid-expedition.

But this chamber… whoever designed it was, if not a worshipper of fertility, then at least a pretty big fan of it. Gold statues of ancient babes and hunks lined the walls, diverse species represented in the array. All nude, all visibly aroused, all posed enticingly. If Daring Do weren't already sweating, she would have started.

And on the central pillar was something even more striking… and, much to Daring’s delight, much more portable. A feminine statuette about a foot tall, carved of smooth yellowish stone. Its proportions were outrageous, its curves outlandish - and Daring Do felt her body respond. She was as sore as she'd ever been in her life, but arousal made her feel loose and limber as soon as she laid her eyes on the idol.

She stepped closer, and the feeling of arousal grew - but then something even stronger took its place. Whatever sexual aura this thing possessed, it couldn't overcome the thing that made Daring Do the mare she was: curiosity. And there was something very curious about this idol.

Daring Do picked up the statuette and turned it over in her hands. “You look… familiar.”

Before Daring Do could even raise her empty cup, Fluttershy had the teapot in hand, pouring her another cup of floral brew. She kept talking as she poured, eagerly sharing the latest drama in her life. “...And of course Beatrice was… well, I don't know if you know much about badgers, miss Daring Do, but their temperament tends to be-”

The cuckoo clock over the fireplace struck two, and Fluttershy gasped. “Oh dear!” she said, putting a hand to her mouth. “How long have I been talking? You must be so busy, but I've kept you here all this time…”

Daring Do laughed. “Fluttershy, you've been a wonderful host, and you're quite engaging when you speak on the subject of your animals.” Fluttershy blushed, folding her hands demurely over her bosom. Daring Do snuck another look at that bosom, letting her eyes treat themselves to the sight. Listening to Fluttershy had been pleasant - Daring hadn't been lying about that - but looking at Fluttershy was even better. The yellow pegasus favored modest dress, but there was no hiding that body. Under her summer dress, breasts like prize melons bounced and swayed with each motion. With each step, her thick, beautiful thighs and juicy round ass put themselves on glorious display. But she seemed so reserved, so prudish… Daring was tempted to try and seduce her, but she was halfway certain she'd send the poor girl running off in tears. Better to just stick to business.

“We may as well get to the reason I came to Ponyville,” said Daring Do. She reached down to the bag beside her chair, pulled the statuette from it, and set the idol on the table.

Fluttershy’s blush became much redder as soon as she saw the idol. “Oh my,” she said, “that little statue is rather… adult, isn't it?”

“Mmm-hmm,” said Daring Do, smirking. “My editor would use up a lot of red ink if I tried to make a story out of this one. Kids read these books, he'd say.” She rolled her eyes, and muttered: “He'd also have some notes about the lack of conflict…”

“Goodness,” said Fluttershy, leaning towards the idol for a better look, “her bust is rather… and her hips… and her bottom…”

Daring Do couldn't resist. “You're no slouch in those departments either, gorgeous.”

“Oh!” Said Fluttershy. “Um… thank you! But… why are you showing me this?”

“Don't you see the resemblance?”

“To what?”

“To you,” said Daring Do. “The facial structure, the hair, the proportions… granted, yours aren't quite as generous as hers, but you must admit it's a striking resemblance.”

“I… I suppose it is,” said Fluttershy, “but I certainly don't have… one of those. I mean… a… p-p-”

“A cock?” said Daring Do. She placed a finger on the tip of the idol’s erection. It was several inches long, which on a one-foot-tall statue made it enormous. “I know. Well, I didn't know for certain, I guess, but if you had one like this I'm not sure how you'd hide it…”

Fluttershy was beet red now, almost frozen in place by awkwardness. Daring Do could help but smile, although she was starting to feel bad about tormenting the poor kid. “I just thought I'd bring this here to see if you knew anything about it. You and your friends go on adventures too, right? Have you ever done anything that would link you to an ancient fertility temple?”

“Um… I’m sorry, but nothing comes to mind. But since you went to the trouble of bringing the statue here, I suppose I could take a closer look…” Fluttershy took a deep breath and extended her hand toward the idol. She couldn't deny that the resemblance was eerie, as if someone had taken her already embarrassingly curvy body and exaggerated it in every way imaginable…

Her fingers came within inches of the statue - and then she drew them back as an arc of static electricity jumped from the stone idol to her hand. “Oh!” she yelped.

Daring Do had been looking down at her bag, trying to retrieve her notebook, when the spark jumped from the statue to Fluttershy’s hand. She jerked her head up, too late to see anything happen. “What?” she said.

“Oh, nothing,” said Fluttershy. “But I'm afraid I don't know anything about the statue. I'm so sorry I couldn't help you… I don't want to take up any more of your time…”

Daring Do put the idol in her bag and stood from the table. She could tell that Fluttershy - in her confrontation-averse sort of way - was asking her to leave. She was fine with that; she felt guilty about tormenting the shy, beautiful pegasus with erotic statuary, and Fluttershy had seemed sincere when she said she didn't recognize the statue.

“Thank you for your time, Fluttershy,” said Daring Do. “And your hospitality. I'll let you know if I discover anything.”

Fluttershy followed Daring Do to the door and closed it behind her. She felt her racing heartbeat grow calm now that she was alone - which was to say, surrounded by small animals - and she collapsed into a chair, pouring herself the last of the tea.

As the evening rolled around, Fluttershy felt herself growing frustrated with her daily chores. Her clothes seemed tight and constricting, and there was a gathering heat between her thighs. Fluttershy had rarely felt so intensely, insistently horny, and the unfamiliar feeling made her nervous.

Was it the way Daring Do had looked at her? She'd had admiring eyes on her before, and she’d never reacted like this. Was it that statue? There had been something strange about it, and something had seemed to happen when she touched it… but she didn't feel that unusual.

She was sure of one thing - a hot shower would do her a world of good. She stripped off her clothes on the way to the bathroom - she wasn't concerned with modesty when it came to her animals - and stood nude in front of her bathroom mirror. She didn't look any different, as far as she could tell. That was a relief.

She stepped into the shower and turned on the taps, sighing as the hot water hit her bare skin. It felt so good to have those tight clothes off… to feel the water cascading down her body - but it wasn't doing a thing to quell her burning lust.

She reached down to touch her marehood, intending only to prod at it, as if her sexual frustration were a fresh bruise. But as soon as her fingertips brushed her wet lips, the sensation filled her body, invading every capillary from her head to her toes. This couldn't be ignored . any longer, or even delayed; she needed relief.

She got more fingers involved, exploring herself and finding each touch rewarded with waves of pleasure. She didn't have much experience with self-pleasure - her prudish demeanor was no mere act - but she got the hang of it quickly. Some investigation revealed that certain spots were more sensitive than others - and finally she discovered a half-remembered bit of anatomical trivia from health class - the clitoris.

Every animal in the house bolted to the open bathroom door when they heard Fluttershy’s scream - and then they slunk off in embarrassment when it became clear that she was in no danger. Her panting cries grew higher and higher in pitch as she worked at her clit, and she pawed at her body with her other hand, stroking her water-slicked curves, massaging her stiff nipples - until finally the sensation was too much for her body to contain, and it overflowed.

Fluttershy felt a tremendous release building inside her; the waves of pleasure had built into a tsunami, and it was flowing to her core, from every direction - and when it struck, her pussy throbbed and convulsed and released. It released not just its tension, but a powerful flow of femcum, thick and fragrantly feminine. She came like a waterspout in a downpour, ceaselessly gushing into the tub, gasping for breath as her climax went on and on, each convulsion of her marehood producing buckets of cum.

For two solid minutes, she stood in the bathtub, knees shaking, coming with unimaginable intensity. She was distantly aware of a rising warmth around her ankles, then her calves, as her femcum filled the tub faster than it could drain. The sloshing liquid was overflowing the tub by the time the flow even started slowing down, and by the time it stopped, her juices had covered the bathroom tile and were starting to deep out into the hardwood floor of the hallway.

Fluttershy fell to her knees, splashing more cum out of the tub, and groaned wordlessly as her body came down from the heavenly heights she'd soared to. She picked herself up and staggered onto the bath mat, dripping femcum, and looked down at the tub she'd just vacated.

What had just happened was impossible - there simply couldn't have been that much fluid inside her body. And yet she wasn't panicking - her self-love had spread calm and satisfaction all through her body. In a blissful daze, she toweled herself off and trotted off to bed. She knew the bathroom floor was soaked in her cum, but for some reason that didn't bother her. Right now all she cared about was curling up in her nice warm bed.

Fluttershy closed her bedroom door behind her, barely noticing that her bedroom was empty of animals; they weren’t acting fearful, but they were giving her a respectful distance during her evening of self-discovery. That was fine with her; her body still humming with pleasure as she pulled the covers over herself, she settled in for a restful sleep and pleasant dreams.

And her dreams were pleasant - although she woke with a vague memory that they had been somewhat ribald in tone. That impression was corroborated by the other things she woke up to that morning. The walls of her bedroom were splattered with something thick and white, slowly dropping down to settle on the floor. The ceiling hadn't been spared this treatment either; sticky, gooey stains clung to the rafters, occasionally letting loose a thick drop.

And her bed was coated with the stuff. Fluttershy didn't recognize it right away, but it gave off a scent that spoke to a newly awakened part of her, a part that reveled in desire. As she looked over her sticky sheets, something else caught her eye: there was something in bed with her.

That wasn't that unusual, actually; Fluttershy loved to cuddle up with animals on stormy nights. But she recalled that she'd gone to bed alone last night, and in any case she could quite tell what sort of animal was hiding under her sheets. It was about two feet tall, with a body twice as thick - no, three times as thick as Fluttershy’s arm. It was perched on her pelvis - which was strange, as she didn't feel any little paws resting on her body - and it twitched slightly as Fluttershy stared.

Fluttershy peeled the goo-soaked sheet from the creature’s body, only to find that it was no creature - it was a beast. A two-foot-tall butter-yellow penis, jutting from her crotch, with testicles bigger than her watermelon tits. As the early morning fog cleared from her mind, she realized that she could feel it; it was truly hers.

And it quickly revealed itself as the source of the goo that was costing her bedroom walls. As she stared at the quivering, bulbous tip, it jerked and spurted a thick glob, maybe a half-cup of cum, which landed with a splat on Fluttershy’s ballsack.

Fluttershy stood from her bed, feeling her cum-soaked rug squish under her feet. There was something subtly different about her bedroom now - something besides the gallons of jizz that she’d fired off overnight. It took her a moment to realize what it was - the room looked smaller. A careful walk over to her dresser confirmed her impression; everything seemed lower to the ground now.

She leaned toward the dresser, extending her hand to wipe her cum off the mirror, and gasped as her cock slapped against the flat top of the dresser. It was so sensitive - even after ejaculating all night, one touch was all it took to rev it back up.

She placed a hand on the tip of her cock and massaged it softly as she wiped off the mirror. She took a step back and sat on the bed, trying to get a better look at her whole body. She was definitely taller, and that had come with some growth in her existing assets; her breasts were larger, her hips wider. And as for her new additions, they were… breathtaking. Fluttershy had never seen a penis outside of a textbook, and she'd never given too much thought to her own body… aside from the effort involved with finding clothes that fit.

But now she could tear her eyes away from her reflection. Her body was so big, her curves so wide, her cock so powerful and brimming with cum. Her gigantic balls rested on her thick thighs, and she placed a hand on them, feeling them slosh and gurgle like a hungry tummy. As she rested her hand on her sack, she realized that she'd been hearing a low sloshing sound since she woke up - and she hadn't given it much thought, since there was so much else going on. But now it was clear that her balls were the source of the sound. Her cock had pumped out impossible amount of cum throughout the night, and her nuts had been churning all this time, tirelessly producing more cum.

Fluttershy rubbed her rumbling ballsack and caressed the head of her cock. She should have been panicking - this whole situation was miles outside of her comfort zone - but something about this felt soothingly natural. All she cared about now was her cock and balls - these wonderful new additions to her body that she was just getting to know. If her balls were churning up a fresh load, then she'd just have to release it - and she was eager to feel her cock cum when she was actually awake.

Her shaft was slick with cum, making it easy to slide her hand along it. It was a landscape of pleasure, warm flesh ridged with veins, every touch making her balls gurgle with greater intensity. She moved her hand to her tits and teased her nipples, adding tiny shockwaves to the gathering sensation in the core of her body.

She wanted more. She'd spent her whole life ignoring her body's capacity for pleasure, but now she wanted everything it could provide. Her two hands were bringing her more physical fulfillment than she'd ever had in her life, but she knew there were higher heights. Fluttershy had never watched a porno, so she was on her own when it came to dreaming up ideas… but even she couldn't ignore the possibilities that her massive tits provided. She slipped her shaft into her cleavage, sighing blissfully as her wonderfully soft toys embraced her penis.

Her long, heaving breaths made her tits rise and fall, and the pillowy yellow flesh touched her cock all over. Her fingers stroked the base of her cock, picking up speed as she built towards climax.

Her eyes settled on the tip of her cock, poking up from between her boobs. It was a darker hue than the rest of her shaft, almost orange in color, and the slit was producing a slow but constant flow of precum that flowed into her cleavage and oozed down her body.

A mare with more sexual experience that Fluttershy might have arrived instantly at the decision to put her mouth on the fat, bulbous tip of her two-foot cock, but for Fluttershy the idea formed slowly as she gazed down at herself. She was struck dumb by just how beautiful she'd become; her body was strange and messy, and so big - but it felt perfect. It felt natural. And the glistening tip of her cock called out to her. Her whole body cried out to be explored, to be loved - so that in time that love could be shared with others.

Fluttershy kissed the tip of her cock, licking up the precum, tasting its wonderful musky sweetness. Then she darted her tongue into her slit, tasting herself more deeply, and passionately made out with her own cock. She stroked herself faster, hungry for release, thirsty for the hot, thick load that her balls were noisily brewing. She released muffled squeaks and moans into her cockhead as she kissed and licked at it, feeling the climax rise through her shaft. Her balls tightened, and with a glorp that you could have heard from the hallway, they began to pump Fluttershy’s load up the length of her cock. The shaft bulged with the flow of spunk, and when it burst from the tip, it filled Fluttershy’s mouth in an instant.

The flavor was rich and sweet and delightful - but the flow was too much for her. She jerked her head back, allowing her spunk to rush out unobstructed, and watched as it shot to the ceiling like a geyser. It splattered on the ceiling and rained down in thick globs, coating Fluttershy and her bed in a fresh layer of jizz.

Her cock spasmed violently with each jet of cum that shot through it, eventually pulling itself free of her cleavage. Now facing the dresser, it fired rope after thick rope of cum, knocking perfume bottles and framed photographs aside, obscuring the mirror that Fluttershy had wiped clean, and seeping down into the dresser drawers. Her cum was so thick that it gathered in a goopy pile at the base of the dresser, growing larger with each outpouring.

Fluttershy fell back onto the bed as her orgasm started to wind down, and her gushing cock flopped as she fell, flinging a splatter of jizz along the back wall. The rest of her load oozed out from her twitching tip, pouring over her tits as she lay there panting on her bed.

And after a restful moment she rose from the bed, surprised to find herself energized - rather than exhausted - by her climax. “I've made quite a mess, haven't I?” she laughed, looking at her jizz-soaked surroundings. It occurred to her that she was far more relaxed than she had any right to be. The Fluttershy she knew would have been panicking over the cleanup job alone, much less everything else that was going on.

But her mind was unburdened. She didn't feel like a different person, exactly; it was more like a balance had shifted. Her anxiety wasn't gone, it just seemed… smaller. And Fluttershy was looking forward to seeing who she could be, now that she wasn't in its shadow.

But living her best life wasn't all about self-gratification; she also had responsibilities. There were errands to run, and while she was in town she supposed it would be a good idea to talk to Twilight. Her transformation was starting to seem like one big upside, so she was in no mood to seek a “cure,” but the town’s resident magical expert should at least be informed.

Humming a cheery tune, she headed to the bathroom for a much-needed shower. Today was starting out great.

Chapter 2

The morning’s shower went by without any real incident. Fluttershy, having just splattered her bedroom with copious gallons of cum, didn’t have any immediate need for release - although the churning fullness in her nuts told her that she very likely could cum again if she cared to.

But she was happy just to feel the water running over her skin, washing off the thick layer of cum she’d coated herself with. As the hot water cascaded down her body, she realized that it wasn’t just her cock that had awakened: every inch of skin crackled with pleasure, turning the pressure and heat of the falling water into pure bliss. The shower took a little longer than usual; she was taller, and every curve of her body was wider, so there was more of her to wash. But she was happy to take her time; simply being alive and feeling things was such a delight now.

All that enjoyment had consequences, though; she’d developed a half-chub, which meant about eighteen inches of thick yellow pony meat to towel off and stuff into a pair of pants. Before leaving the bedroom, she’d dug through her dresser and found that the bottom drawer had escaped the flood of cum from her morning emission - and luckily enough, that drawer contained some of the only garments that had any hope of fitting her: a blue hooded zip-up sweatshirt and a pair of gray yoga pants.

Once she was dry, she pulled her arms and her wings through the sweatshirt. That was the easy part; those attributes hadn’t grown nearly as much of the rest of her. Things quickly got harder: the open front of the zip-up hoodie couldn’t really close around her breasts, which had grown to be, individually, about three times bigger than her head. Trying to get her tits inside the sweatshirt involved a lot of smooshing and squeezing - bit by bit, she worked the zipper upwards, hugging her boobs with her arms to compress the squishy globes.

It felt great. Her breasts had always been big and bouncy, but at their new size they were squishier and softer than anything she’d ever felt. And touching them was delightful; even if she didn’t have a reason to, she could have passed an hour just feeling up her tits.

In time she got the hoodie halfway zipped up, covering nearly half of her tits. That was about as good as it was going to get, she figured, so she lifted the yoga pants and began to work them onto her body. As with the sweatshirt, the job started easy and quickly got much harder. Her lower legs had expanded a bit, but her thighs had ballooned - and her ass had exploded into a big, jiggly yellow bubble. Once she had them halfway up, she was hopping up and down, working herself a quarter-inch deeper into the stretchy pants with each jump - and making her whole body wobble all over the place.

But all that wobbling was making her job harder. Because it wasn’t just her legs and her ass she needed to get her pants around: she also needed to shove her big yellow cock and balls in there too. And the more she touched herself, the more she jiggled, the harder her cock became and the bigger her sloshing balls grew. It hadn’t been a half hour since her last orgasm, and she was already nearly bursting from the effort of getting dressed. If she was going to get these pants on, she needed to drain her nuts and get her cock soft.

Still working the pants up her buttery thighs, she hopped down the hallway and into her living room. The simple act of moving her body was getting her stiff cock worked up; its bulbous tip began to spit globs of pre onto the hardwood, leaving a sticky trail behind her. Feeling her shaft pulse and begin to pump its load upward, she hopped to the front door and threw it open, aiming her throbbing cock at the great outdoors.

The first splash of cum shot twenty feet down the path, most of it splattering against the leafy branches of a tree. The subsequent shots didn’t have quite the same velocity, but they still sent buckets of Fluttershy’s wonderful white cum in every direction, painting her front walk a creamy white. Fluttershy cried out in bliss, hopeful that the sight and sound of her climax would reach some pony somewhere… although her home was so far from town that that seemed unlikely.

When her orgasm ended, her balls had shrunk considerably; they were now the same size as her breasts, which was a big improvement. Her cock didn’t shrink too much, but it softened, allowing Fluttershy to cram it into the front of her yoga pants. Fluttershy’s clothing was now technically in line with pony society’s expectations; her nipples were covered, as were her bottom and her genitals. But she was still outrageously lewd, with her tits brimming over the top of her hoodie and her cock’s outline perfectly visible beneath the tight yoga pants. She found a pair of sneakers by the door and yanked them on; her feet had grown much less than most parts of her, but they were still a tight fit.

Leaving the house usually filled Fluttershy with a low hum of dread. But today, she couldn’t wait to show herself off.

“Fillies and gentlecolts,” said Princess Luna, casting a glance at the index cards on the podium in front of her, “Thank you all for coming. I hope you are all as delighted as I am to… er…”

A strange sensation brushed across Luna’s acute magical senses. She couldn’t place what she was feeling, but it was so familiar that it gave her pause, throwing off her focus. It was similar to the way she felt when her sister came near… but she knew that feeling well, and this wasn’t quite it. It didn’t seem dangerous, though, so she faced the seated crowd and returned to her notes. Where was she, again?

“To be attending the opening of Canterlot’s newest museum of modern art. The collection gathers pieces from all over Equestria, bringing together some of the most bold and original voices in the art world. I have even had the privilege of visiting the dreams of a number of these artists, and it pleases me to see how their talents have captured the raw, turbulent imagery of their own subconscious and brought it into the physical realm.”

Luna felt a warm flush come to her face as her prepared notes brought pleasant memories to the forefront of her mind. Pushing aside her index cards, she looked over the audience with a sly smile. “You know,” she said, “Over the years, I have acted as a muse to many an artist. If I happen to enter the dreams of a painter, for example, they may ask me to pose for them… and if my body inspires them so, then I can hardly refuse. I may even pose nude for them, if asked nicely…”

This was not what the high-class ponies in attendance were expecting to hear from their princess, and it showed on their faces. But Luna was too absorbed in her own words to consider changing course.

“And for all the ponies who think fondly of me in their dreams,” said Luna, “there are just as many who dream of my dear sister Celestia. And who could blame them? She is a perfect specimen of beauty. Even after all these years, her body is still captivating, even to me…”

The ponies in the front row began to notice something odd about Luna. She seemed to be growing taller, her body gradually rising higher and higher above her podium. Not just taller, but wider, too: her breasts began to push against her black dress, and her bottom - already famously wide and round - grew twice as fast as the rest of her, inflating like a midnight-blue balloon.

Luna didn’t seem to be consciously aware of her own growth, although the way she arched her back and ground her thighs together made it clear that she was feeling something. “Although strict representationalism has fallen out of fashion,” said Luna, “My sister’s body has remained a source of inspiration to artists throughout the centuries. The enduring beauty of her form, the raw sensuality of her shape… it’s no surprise that artists wish to recreate a sexual goddess in their work.”

Luna’s butt was wider than the podium now, bulging out on both ends, pushing out the sides of her black split-front dress. The cutie marks of both cheeks were exposed, two pale moons growing larger with each beat of her heart. The audience, too cowed and confused to speak a word, simply gawked as she grew.

“Take, for example, the piece beside me,” said Luna, gesturing to a sculpture to her left. It was so nearby to her, in fact, that her left asscheek was beginning to press up against it. “Such supple curves in hard white marble… abstract as it is, can you say that it does not remind you of princess Celestia? Goodness, how can one behold her body and not feel the flames of passion stoked? Of course, she is rightly jealous of my rump… its size is the one thing she lacks, as I am sure you can see for yourself…”

As she grew in height, her hips ascended above the top of the podium, treating the crowd to another unexpected sight. Her dress was just barely holding on at this point, draped loosely over an ass the size of a beanbag chair, and there was a new shape under its black fabric. A snaking protrusion stood front and center, pulsing with little spurts of growth, growing thicker and longer every second.

“Do you know the very nicest thing about having a great big ass, ladies and gentlecolts?” said Luna, flexing her hips to make her ballooning cheeks wobble up and down. “It’s how good it feels to get fucked. Oh, when these big round cheeks have a nice fat cock buried inside them, it is pure bliss. Of course it takes a long and powerful cock to penetrate an ass of this size and still have length left over to pound my tight asshole… and it takes a thick cock to properly fill me…”

Luna was going wild now, throwing her head back, bouncing her hips. Her dress, barely covering anything by this point, finally gave up: Her deep blue tits burst from their confines, and her lower body - cock and balls and butt - finally threw off the folds of fabric draped over them. She stood eight feet tall, a veritable titan, but her butt was quickly outgrowing the rest of her. It was seven feet wide and showed no signs of slowing - and its expansion finally toppled the fine marble sculpture she had so recently praised. The motion of her hips sent her cock whipping forward, and its immense weight knocked the podium aside.

“A nice big cock like this is good for so many things,” said Luna, stroking the base of her shaft. It was thicker around than most ponies’ torsos, and it was growing longer fast - its head had just hit the tiled floor, and its growth was pushing it forward, making it creep along the corridor between the two groups of seated ponies. It crept slow and silent, like an anaconda the color of midnight, attracting nearly as many eyes as her enormous rump.

Her ass was mind-bogglingly huge now, so big that someone standing behind her would have seen nothing but the two enormous twin moons. Each cheek was a good ten feet in diameter, big enough that the rest of her body could have comfortably curled up inside. The sight would have been absurd, were her rump not so perfectly round and beautiful.

“It’s a pity,” said Luna, her voice dropping into a low moan, “that there is not more eroticism on display here. Why are sculptors not erecting tremendous cocks with bulging veins? Why are painters not painting sultry nudes with acres of exposed flesh? Why are performance artists not pleasuring themselves on stage for the delight of a live audience? It falls to me to serve as an example…” Her cock, extending halfway down the row between the seats, began to thicken and stiffen and rise. And her balls, big enough that they grazed the floor, churned and gurgled with seed…

Outside the new museum, passersby glanced at Canterlot’s newest cultural landmark. The doors were shut tight for the private event, the modern, windowless facade silently facing the street. And then it began to rumble, as if a wave was crashing against it. Ponies stopped to look, peering at the rattling doors - and saw the doors blow off their hinges as a flood of creamy white cum burst through and ran into the streets.

Princess Celestia knew, better than most, how important it was for a pony to have a hobby. An immortal life gave her ample time to get bored, and over the centuries she filled her spare hours with pursuits of all kinds. Some decades she threw herself into pottery, while in others she became an accomplished amateur in a competitive sport. And recently, she’d returned to a hobby she’d pursued several times before: live theater.

And it was particularly nostalgic to be playing the female lead in a Neighkspeare play. Celestia had been a patron of the now-famous playwright, and it pleased her to see how his work had endured throughout the centuries. And still popular, too; the house was packed - although Celestia’s presence was probably the primary reason for the sellout crowd.

The first act was drawing near to its conclusion; its penultimate scene was one in which Celestia, playing a beautiful bride-to-be, monologued about her love for her stallion. Alone on stage in a long, flowing white dress, she stepped downstage and spoke.

“My love, return, do not abuse my heart,” she said, placing her hands to her chest. “This distance wrings such anguish from my breast.”

Neighkspeare had used the word “breast” to refer to the chest in its entirety, a usage that was somewhat archaic now. But with her hands resting on her bosom, Celestia couldn’t help but smile at the word - and she couldn’t help put press down with her fingers, groping the soft flesh of her tits. They felt extra sensitive today - perhaps even larger than usual?

“My tits, they swell with passion, round and full,” spoke Celestia - and then stopped herself. Oh dear, that wasn’t the line! All through the audience, ponies glanced at one another in confusion; even those who didn’t know the play by heart seemed to guess that something wasn’t right.

Celestia could have simply corrected herself, but the intensifying pleasure in her chest made her feel a bit playful. Neighkspeare’s sense of humor had a decidedly lewd streak, and he would have enjoyed a bit of saucy ad-lib.

“My cleavage longs to stroke a throbbing cock,” she said, slipping her hands under breasts that were already swelling larger than her head. “My mem’ry shines with boobjobs from my past. Thick cocks I’ve brought to climax with my tits… The cream that flowed like fountains from the tip…”

The wedding dress was enchanted to re-size itself to any wearer - which is how it managed to accommodate Celestia’s towering stature - but the growth of her tits was testing its limits. And her tits weren’t the only part of her that was growing; her whole body was growing taller, and her swelling ass lifted the back of the flowing dress. And in front, something surprising was rising up, a stiffening shape tenting the dress. The audience might have guessed that what they were seeing was a cock… though it quickly grew too big to possibly be real.

But when the shape grew large enough that the white wedding dress could no longer contain it, the truth became undeniable. A bulbous tip emerged from beneath the hem, and with her dress lifted the audience could see the two fat, round balls that hung past her knees.

But Celestia’s breasts were growing faster than anything else. By the time they hung down to her waist, the dress’ enchantment could no longer hold out, and they burst into the open, two wobbling globes topped with fist-sized nipples. They were flawlessly firm, gravity-defying mammaries, but their sheer size made them dip lower and lower until she was nearly giving herself a boobjob. Her cock, surging forward in length and girth, was about a foot thick now, and three times as long - and her ballooning breasts fell on either side of it, embracing the shaft in velvety warmth. Her breasts hit the floor just before her balls did, and Celestia leaned forward, rocking herself back and forth, fucking her expanding tits with rhythmic thrusts of her hips.

The stunned audience could only watch as the quivering tip of the sun princess’ cock began to drip with thick gobs of pre - and her nipples began to flow with mouthwatering milk. The flow of milk and cum grew stronger as Celestia pleasured herself - her nipples poured with white rivers, and her cock fired quarts of pre into the air, turning the first three rows into a splash zone. Her body still expanding, the pace of her thrusts still quickening, Celestia began to moan with bliss, her voice rising - and her nipples became geysers of milk, raining thick, delicious drops on the audience. Her cock followed not a half-second later, wildly firing ropes of cum so thick and heavy they could have knocked a standing pony to the floor. And with each gush, each splatter, there was more - her growing body offered up greater and greater volumes. And a cry escaped her lips, just one word:

“Sultry”

Cadance spun her fountain pen in her fingers as she contemplated the blank space on the page before her. Despite recent inroads, griffin-pony relations had always been a little thorny. The griffon kingdom was never hostile - at least not in the political sense - but they were quick to take offense. Cadance wasn’t even sure there was a “right” way to word this letter… but she certainly had to try.

Her pen hovered over the word friendship, and with her horn she readied a spell that would remove the ink from the page. Was that the word she wanted? Would alliance better appeal to the pride of the griffons? Sighing, she erased the word and put pen to paper -

And drew an erratic line across the page as her writing table shook beneath her pen. “Damn it!” she swore, gripping the table’s edge to steady it. “Serves me right for trying to write a letter on a train…”

Groaning, she leaned back in her chair and looked out the window. The train was somewhere between the Crystal Empire and Griffinstone now, which meant the environment was transitioning from frozen to barren. It was nice enough to look at, though, if you happened to be on a finely appointed private car. While not specifically meant for royalty, the car was certainly up to her standards; there were opulent plush seats, pleasing floral wallpaper, even a modest chandelier - and a writing table that magically hovered several inches off the ground, insulating it from the train’s bumpy ride.

That’s right, thought Cadance - the table hadn’t suffered from any bumps before now. What suddenly jostled it, then? And what was that odd feeling between her legs?

She looked over the far edge of the table and saw a growing pink shape - something thick, something the same color as Cadance’s body… something veiny… she reached across the table and grabbed it, and then she gasped as a surge of physical bliss shot through her body. The veiny shaft twitched, and by this point it was big and strong enough that it didn’t simply jostle the writing table; it threw it aside, tossing her pen and paper against the wall.

“Oh wow,” gasped Cadance, gripping the base of her cock with both hands. It hadn’t been there a moment ago, but it felt so natural… and it was growing so big. It was easily two feet now, thicker than Cadance’s thigh, standing above a set of balls that dangled halfway to the floor. And as she looked down at herself, she realized that a growing cock wasn’t the only thing about her that was changing. Her ass was expanding, plush cheeks lifting her higher in her seat. And her body was stretching taller as well, already so high that her spiraling horn bumped against the chandelier. Her tits, which had never been small, were swelling into ripe pink melons.

But her cock was growing faster than anything else. Cadance felt magic flowing into her, filling and bloating her cock and balls bigger each second; with each beat of her heart, her penis gained an inch, then two, then three - and sooner enough the fat tip of her shaft bumped against the door of her private car. Precum smeared against the door, pumping from the tip quart by quart.

Her cock was immense, hugely out of proportion with her body… but it felt so right. As if this was something she, as the princess of love and passion, always should have had. Cadance stroked her shaft, willing it to grow, eager to see her body blossom into something bigger and more beautiful.

A forceful surge of growth caused her expanding cock to bust through the door of her private car. Not just the door, in fact, but the entire front wall of the car - and the back wall of the car in front of hers. Her dick grew its way into the dining car, knocking tables aside, punching its way through the bar, pinning ponies against the walls of the train car as its girth grew.

The train rattled on the tracks as its most important passenger grew bigger and heavier. Her cock kept punching its way forward, outgrowing the dining car and penetrating the passenger car beyond. By this time, its diameter was nearly equal to that of the train car itself; what the passengers saw, as the back wall of the car burst open, was an enormous pink cockhead bearing down on them and gushing precum.

And back in her private car, Cadance had nearly outgrown her compartment completely. She was bent double, her wings up against the ceiling, still stroking her immense cock - and the next surge of growth caused the entire car to burst open. Her body straightened, her wings flexed, and she came - down the length of four train cars, hundreds of gallons of cum rumbled through her cumvein and burst from the tip, flooding the cars ahead. And with her body finally freed from the confines of the private car, her kicking feet eventually dug into the ground, acting as brakes that brought the train to a halt.

Cadance stood, dragging her immense cock out of the train cars she’d inadvertently fucked. All through the train, cum-soaked ponies rose to their feet and beheld their towering princess. Cadance, lusciously curvy and majestically hung, was fifty feet tall and still growing - and there was a feeling, a pull drawing her attention southward. She didn’t know what waited there, but she set out on foot, drawn to the seductive beacon. The ponies on the ruined train watched her stomp away, her immense pink balls swaying below her knees and her still-hard cock rising higher than her head.

Fluttershy strolled into central Ponyville, still marveling at the change that had come over her. Here she was, tits bigger than ever, a cock practically bursting from her tight yoga pants, and she couldn’t wait to show herself off! Just yesterday she’d been meek little Fluttershy - and of course, before she’d been Fluttershy she’d been -

Hmm, now that was an odd thought. She couldn’t quite complete the sentence her mind was trying to form, but she couldn’t shake the feeling that she’d been someone else before she’d been Fluttershy. The question nagged at her, but she put it to the back of her mind as she strolled into the center of town. She’d been attracting attention - and followers - as soon as she came within sight of Ponyville, and she was positively basking in their admiring gazes.

And they weren’t just looking at her; every pony who caught sight of her big, jiggling body seemed to acquire a new appreciation for their own body. Mares groped their tits openly, and stallions adjusted themselves as their cocks grew stiff inside their pants. Fluttershy wasn’t used to seeing that sort of behavior - pony society tended to be sexually reserved, which suited her old self just fine. But now blouses were becoming unbuttoned and bulges were rising, and Fluttershy wanted to see more - more public lewdness, more lurid acts, a sexual surge consuming the town. Her cock stirred in her yoga pants, uncoiling itself as it grew stiffer, and her tits began to swell.

The center of Ponyville was never swarming with crowds, but at midday it was the small town’s densest hub of activity. There were friends chatting over lunch, stalls selling fresh fruits and veggies, and couples holding hands - but as soon as Fluttershy came into view, every eye was on her. All that attention - all that desire - seemed to be flowing into her. As a pegasus, she’d never channeled magic - but the feeling was somehow familiar, as if she’d done it a thousand times before.

And it didn’t just flow into her: it flowed through her and back out into the world, stronger and more pure. Like an invisible wave, arousal spread through the center of town, eliciting a chorus of moans from ponies near and far. Commerce and conversation ground to a halt as mares and stallions groped themselves openly.

Seeing the effect she was having on Ponyville made Fluttershy’s cock swell to full hardness - and her yoga pants, stretched to the point that they were nearly transparent, finally snapped and burst from her body. Her butt, itself a contributor to the strain on her pants, burst free and surged in size until the wobbling cheeks hung down past her knees. And her breasts exploded from within her hoodie, tearing apart the zipper that held it closed. Now free to stand tall, her cock embedded itself between her tits, rising high enough that her lips grazed the tip when she opened her mouth.

Fluttershy wrapped her arms around her tits, squeezing her cock between them. Her balls, now hanging down to her ankles, sloshed with thick fluid, swelling as they prepared a volcanic load. And the sight of all those ponies rediscovering their bodies made her mind race. What if they could all feel even a fraction of what she was feeling? What if their bodies could grow bigger and awaken to this bliss…

Fluttershy had never cast a spell before - and yet, like the feeling of desire flowing through her, the sensation of imposing her will onto reality was oddly familiar. Moments after she imagined sharing her growth with Ponyville, it happened - blooming bosoms split shirts wide open, and cocks of all colors burst through stallion’s pants, stiff and growing, none of them shorter than a full foot long.

Once again, the desire of the ponies around her flowed through Fluttershy, and she returned it to them - but not before it caused her body to swell once again, ballooning in all directions. Her ass and her balls hit the ground, her tits stuck out four feet in front of her, and her cock rose higher than the crown on her head, its tip burbling with pre. The sight of her growing body drove the the ponies’ passions wild: all across the center of town they stopped groping themselves and tackled each other, their bodies still swelling as they gave in to lust.

And this new wave of passion hit Fluttershy, spurring more growth. It seemed like this feedback loop could go on forever, growing Fluttershy into an outrageously curvy, monstrously hung titan.

And picturing herself that way - as a towering goddess with tits like mountains and a cock that scraped the sky - made the memory of being someone else hit her harder than ever. So hard, in fact, that the old Fluttershy began to reassert herself. The changes she’d been going through had been pleasant, but now she realized there were more changes coming. She’d be altered forever, leaving behind her old life, never to spend another day as the pony known as Fluttershy. The prospect scared her, and just at the moment the floodgates of growth began to burst... she held herself back.

But there was too much power behind those changes, still fighting to get out. So rather than bursting all at once, the metaphorical dam began to crack. Her right arm - and only her right arm - grew in an instant, becoming three times as long is it was before. For the first time since she’d woken up this morning, Fluttershy began to feel self-conscious about her body; her tits, ass and cock were all still magnificent, but having one huge, out-of-proportion arm wasn’t the look she wanted. She did find that it was now long enough to reach around her enormous rack and squeeze one fat nipple, and that comforted her a bit.

As her resistance weakened, the other arm grew to the same length, and now she was squeezing both nipples, milking herself, coaxing a creamy white flow from both fat nips. That made things a lot more fun, and she entertained herself in this fashion for a moment before she felt her shoes grow uncomfortably tight…

Shifting her feet beneath her huge hanging ballsack, she tried to pull her shoes off - but then her shoes exploded as both feet grew to huge proportions.They grew much, much more than her arms had; each one became ten feet long, nearly as long as Fluttershy was tall. “Dear me!” said Fluttershy, struggling to lift her legs, “this is rather awkward…” She took a few steps forward, her gigantic feet shaking the earth. “Goodness, I won’t be able to get around like this.”

And then her body rocketed upwards as her legs grew to match the size of her feet. Her body was some forty feet in the air, standing on legs taller than any building in Ponyville - with thighs wider than the square footage of her house. Her ass had grown along with her legs, and now it was big enough that it could turn any two buildings in Ponyville into twin craters.

But she would never do that. Fluttershy loved the ponies in her town - and she loved them even more dearly now that she saw them from so high up. She rarely flew this high - and at the moment she couldn’t fly at all, not with her body so enormous and so absurdly proportioned…

Then, with another spurt of localized growth, she had a sixty-foot wingspan. She stumbled as her center of gravity abruptly shifted, and she flapped her wings to steady herself, sending a powerful gust sweeping over the center of town. She stumbled, taking an awkward, earth-shaking step forward - and fortunately not stepping on anyone. Just as she was starting to regain her balance, her cock and balls grew; her nuts slammed to the ground like meteors, and her cock pierced the clouds like a thick, veiny pillar.

Fluttershy couldn’t stay standing, not with such immense weight suddenly added to the front of her body. She was falling forward, her enormous body about to crash to the ground and demolish half of Ponyville. There was no way to avoid landing on dozens of ponies - and the tragic inevitability was already breaking Fluttershy’s gentle heart…

And that moment of pure emotion unlocked something inside Fluttershy. A memory of loving and caring for all the ponies around her, enriching their lives with pleasure and growth. Before she was Fluttershy, she had been Sultry Heft, an equal to the princesses, an avatar of sexual pleasure. It had been wonderful to be Sultry - and now that her memories of her old life were returning, she realized that the time she’d spent as Fluttershy would never truly be lost. As the meek, animal-loving pegasus, she’d learned so much and made true friends… but now it was time to move forward. To become more.

All at once, the rest of her body grew into its proper proportions - which of course meant that her breasts, ass, cock, and balls were tremendous. Her body had been toppling over, just about to crush the ponies beneath her - but now she felt perfectly balanced, and it was simple for her to push off from the ground, flap her wings, and fly away from Ponyville. Below her, mares and stallions with enhanced bodies were making passionate love, barely taking notice of the danger that they’d narrowly avoided.

Her connection with the princesses was tugging at her, and she followed the pull, feeling her body grow as she flew. She’d already hit a hundred feet, but her body was still expanding in all directions, each curve blossoming in size as her body permitted itself to reach its proper size. Her tits grew so large that they almost scraped the ground, and Sultry was forced to pull up, flapping her wings harder to give her growing body room to maneuver.

As she flew miles northward, roads and towns dwindled in size beneath her. She was more than five hundred feet tall as she passed by Cloudsdale, the wind from her wings pushing it gently aside. When she passed a mountain range to the north, her enormous dangling ballsack smacked into a mountain range, triggering an avalanche and sending a minor tremor through the earth. It didn’t hurt, to Sultry’s surprise; instead, the jolt made her cock spurt a few swimming pools’ worth of precum onto the ground below.

She touched down in a bare spot of countryside, where her senses told her the others would gather. She flattened trees underfoot as she landed, casting a long shadow over the empty plains. She estimated her heights as a thousand feet, which felt very natural now; with her memories returning, she realized she’d spent far more time at this height than at the height of a normal pony.

From the north, a pink shape appeared in the sky and quickly grew larger. Sultry turned her head to the south and saw two similar shapes, one white and one dark blue. As they came closer, their individual shapes became more distinct: The white pony had tremendous curves hanging down in front, and the blue one was hauling a similarly huge pair of curves in the back. The pink one didn’t have quite that level of curviness, but she did have a gigantic, soft cock dangling from her body, flanked by a pair of fat pink balls that rivaled the curves of the other two.

All three joined Sultry in the clearing, making graceful landings that nonetheless made the earth shake. They were all enormous, although none of them quite compared to Sultry herself. They were each about a hundred feet shorter than her thousand-foot stature, and Sultry possessed all of their best attributes - she had an ass like Luna’s, tits like Celestia’s, and a cock and balls like Cadance’s.

“Sultry!” said Cadance, stomping across the countryside to embrace her, “You’re finally back! You really took your time getting reincarnated, didn’t you? But now you’re here, and we finally have our true bodies again…” She leaned her head into Sultry’s chest, and her giant pink cock began to grow stiff again.

“I cannot blame her for taking her time,” said Luna. “Celestia and I had… strong words for her in the times of Equestrian unification. In those times of struggle, we considered Sultry’s effect on the ponies around her to be a distraction that imperiled the future of our civilization.”

“But we missed you terribly,” said Celestia. “And without your power, our bodies dwindled to the modest proportions we have had for centuries. But now you are back, and our forms are restored… and with Equestria as powerful and prosperous as it is, a little distraction doesn’t seem so bad…”

“I am happy you feel the same way, sister,” said Luna, backing her mountainous ass up against her sister. “Did you miss my big rump, Tia? There's simply none larger in the whole universe, and I know you adore it…”

“I do, dear sister,” said Celestia. Her cock rose, digging into the firm flesh of Luna’s butt. Her asscrack was hundreds of feet deep, big enough for a normal pony to get hopelessly lost inside - but Celestia’s cock was big enough to cover the distance, with plenty of length left over to penetrate her sister’s tight, dark pucker.

Cadance laid herself down against a mountain range, spreading her thick pink thighs. “Sultry,” she said, “let me be your first fuck as a reborn goddess. I want to feel that big yellow cock…”

Sultry knelt in front of Cadance, lifting the pink princess’ ten-ton ballsack to expose her slick pussy. “You're beautiful, Cadance,” she said. “It's been so long since I've been in my true form… my memories of using my giant cock are so dim, but once I'm inside you I know those memories will be crystal clear…”

She lowered herself onto Cadance, penetrating her wet lips with the fat tip of her stallionhood. Cadance’s pussy was cavernous, but Sultry’s cock filled it tight, sending a jolt of delirious pleasure through Cadance's body as hundreds of feet of girthy stallionhood slowly entered her love tunnel.

“Ohhh fuck…” groaned Cadance, flexing her wings and throwing her head back as Sultry went balls-deep inside her. “Mmm, and I thought Shiny was hung… but no one measures up to you, do they? You're the absolute embodiment of sex… body and soul…”

Sultry began to pump her hips, moving literal tons of cock in and out of Cadance's cunt. “Oh, this is wonderful,” Sultry gasped. “I can feel every single inch of my enormous cock… mmm, it was good before, but now that it's massive it feels so much better… Ooh, it’s so nice to be big again…”

“It certainly is,” grunted Luna, digging her fingers into the earth as her sister’s cock slid deeper into her ass. “I had nearly forgotten what it was like to have a divinely huge body… and a bottom nearly as big as the moon itself.” She pounded the ground with her fist, moaning as Celestia fucked her asshole deeper. “Ohhh, Tia, I cannot take it… I forgot how good it felt to be fucked in the ass… my rump is so sensitive, I may cum at any moment…”

Luna’s cock was leaking pre in powerful spurts as Celestia began to move her cock in and out. It only took a few spurts for her enormous cock to create a small lake of creamy pre, and the lake grew steadily larger as Celestia pumped her hips faster and faster. Cadance’s cock was shooting even more; her balls were more than twice the size of Luna’s, and they roared with the sound of churning as the load within them grew ever larger. As she lay back against the mountains, her immense pink cock stood upright, firing thousands of gallons of precum straight into the air. Each gout of cum sailed upward, knocking clouds from the sky before splattering back down - some landing on Cadance’s massive rack, some landing back on the tip of her cock and dribbling back down her shaft.

Sultry licked at Cadance’s shaft, drinking the thick pre, and moaned as the taste sent a throb of pleasure through her body. She could feel that she was getting close; her cock was throbbing with seismic force as she pounded at Cadance’s pussy. Quickening her thrusts, Sultry wrapped her arms around Cadance’s cock, steadying herself on it and slipping it between her huge yellow tits. “I’m going to cum, Cadance!” she yelled, slamming her stallionhood into the pink princess’ cunt. “Oh heavens, my balls are so swollen with cum, there’s going to be so much-”

“Mmmph, I need it, Sultry, I need your thick hot cum…” grunted Cadance. “Oh fuck, my big wet cunt needs every drop of your load…”

Sultry came, her cock spurting like a volcano of hot, creamy cum, tens of thousands of gallons of cum shooting deep into Cadance’s pussy. After the first gush, Cadance’s belly was visibly bloated, as if she’d just finished a filling meal - and it grew bigger with each earth-shaking spurt that erupted from Sultry’s cock. Cadance’s own cock, still pointed skyward, quivered and throbbed and shot its load, sending hundred-foot-long ropes of pure white jizz soaring into the air. They splattered all around the landscape, drenching the countryside in Cadance’s liquid love.

“Oh, look at them,” said Celestia. “Do you remember coming like that, sister? Shall I remind you of how it feels to have your enormous ass flooded with your sister’s hot, thick cum?”

Luna could only moan; it had been more than a thousand years since she’d had her ass fucked, but her memories of being an absolute slut for giant cock were flooding back. She clenched her buttocks, tightening her ass around her sister’s cock, her body yearning to be bloated like Cadance’s…

When Celestia came, the voice of the sun princess resounded for miles - and when Luna joined her, they cried out in in blissful harmony. Celestia’s load made her sister’s belly swell, lifting her prone body upwards - and when Luna came, her cock fired a river of cum over the landscape, painting creamy white splatters across long stretches of Equestria. Celestia pulled out as she was still coming, dragging her immense, ivory-white cock out of Luna’s cavernous ass, and pointed the spurting tip at her sister’s backside, shooting off enough spunk to glaze all of Luna’s giant booty - with enough left over to paint her back and her wings white.

“More,” moaned Luna, once again a shameless anal slut. “Someone fuck me again, my ass isn’t full yet, I need cum inside me…”

“Now that I’ve been reborn,” said Sultry, pulling her still-hard cock from Cadance’s pussy, “I feel like I could fuck forever. So if you’re offering…” She lay back, pointing her dick in Luna’s direction. “Why don’t you sit on my cock, Princess Luna?”

Luna lifted herself to her feet unsteadily, hooking her hands underneath her cum-bloated belly as she stumbled towards Sultry’s giant yellow cock. She turned herself around, treating Sultry to a vision of indescribable beauty: the sight of Luna’s big blue ass descending upon her. Between her round cheeks was a canyon that swallowed up Sultry’s cock, and deep within that canyon was a tight pucker that embraced the length of Sultry’s shaft. Once Sultry was balls-deep inside her, Luna began to rock her hips, stirring the tremendous cock in her ass.

“Oh my, that looks like a good time,” said Celestia. “May I join you?” Luna nodded, and Celestia backed her ass onto Luna’s cock, just as the moon princess had impaled her ass on Sultry. “Come, Cadance,” moaned Celestia, “There is ample room for you on my dick.”

“Mmm, sounds good to me,” said Cadance. She took the dick she was offered, sliding her ass onto the long white cock. There was now a stack of living goddesses in the Equestian countryside - Sultry, the biggest and curviest of them all, formed the base, and the princesses were stacked ass-to-cock on top of her, with Cadance at the top - and Cadance’s enormous pink cock standing so tall it could be seen for miles around.

The four of them began to pump their hips, fucking each other with earth-shaking force - and the same magic that had brought them together soon brought them into a rhythm that amplified the pleasure and power that each one felt. With their intimate connection, they shared the sensual bliss with each other; Sultry felt like she was fucking all three of the princesses at once, and Cadance felt the intensity of three towering cocks inside her. For all their nobility, all their power, each and every one of them was reduced to a horny, rutting beast, thrusting faster and faster, wanting only to cum.

Cadance’s big pink ballsack began to swell, the massive orbs churning up a load that would put her previous one to shame. Her nuts pushed her legs apart, noisily swelling and sloshing as the combined sexual energy of their fucking poured into them. Each thrust in Cadance’s ass concentrated that power, readying Cadance for a climax that would echo through Equestria. Her bloated nuts tightened against her body, and her upright cock throbbed and pumped and shot.

All four of them came at once, in fact. Sultry bloated Luna’s already-swollen belly, Luna filled her sister’s ass, and Celestia shot her seed into Cadance. Only Princess Cadance, with the biggest cock among the princesses, fired off her load into the open air.

And the intensity and volume of that load was multiplied a thousandfold by power of Sultry Heft, the reborn sex goddess. Cadance’s towering pink cock became a fountain of cum that shot in all directions, sending thick, heavy ropes of jizz slamming into hills and valleys, roads and towns. For miles around, ponies were knocked flat, drenched by volleys of cum that fell from the sky. One splatter of seed was enough to coat dozens of homes, hundreds of ponies at once. And Cadance kept on coming. All of them kept on coming, their sexual energy building into a critical mass that finally burst, spreading a shockwave through all of Equestria.

When Sultry disappeared from the world centuries ago, more was lost than just the colossal bodies of the princesses. Since her departure, ponies had effectively no libidos, having sex only for procreation. But this shockwave announced the return of the sexual goddess, awakening pleasure and desire all across Equestria. Ponies everywhere felt their bodies growing in wonderful ways - and just as soon as they noticed themselves, they began to notice each other. Passion blossomed all through the land, and a new age dawned.

Twilight Sparkle was usually an early riser, but occasionally a grueling all-nighter made it necessary for her to sleep in. Today was just such a day; heedless of the day’s unusual events, Twilight kicked off the covers, scratched her bottom, and walked to the upstairs window of the Golden Oak Library. As she pulled apart the curtains, her shoulders bumped against her breasts in an unexpected way - almost as if her bosom was bigger than it normally was. There was also an unfamiliar heat between her legs… but Twilight’s orderly mind filed that mystery away for later.

With the curtains pulled back, the window opened onto a landscape buried under a blanket of beautiful, shimmering white. “Look at that,” said Twilight. “I guess we’re in for a white Hearth’s Warming.”
