Puffing Up Poolside

Something had been bothering Celestia. Luna was sure of it.

It was just little things—nothing too obvious—but she’d known her sister for a long time. Accidental turns of phrase. Slip-ups during speeches. A small twitch—or was it a cramp?—in her fingers and eyes. Something was on Princess Celestia’s mind, and Luna was determined to get to the bottom of it.

It might just be stress, she’d originally thought. A monarch who reigned for as long as Celestia had just had to feel overwhelmed once a century. But no—there were none of the standard signs of stress. No lack of sleep, no snaps or arguments. Just the apparent preoccupation with something else, and one too many furtive glances when Celestia thought that nopony was looking.

Well. As a good sister—which she was absolutely determined to be, given the whole Nightmare incident—Luna was firm in her conviction that it was her responsibility to do something about it. There was something on Celestia’s mind, and it was her duty to help her with it. Or at least, she decided, to find out what it was.

That was why she was currently hiding in a pair of bushes, squatting, and peering between a set of branches as Celestia lounged in a lawn chair on the opposite side of a large, welcoming pool.

It wasn’t a real pool. None of this was real, save for the two of them, and even that was questionable. Then again, dreamstuff may not have been solid, but it certainly felt like it. The cool earth squishing between Luna’s toes and the support of the chair beneath Celestia’s body were proof enough of that.

Luna blushed slightly as she noticed Celestia softly stroking her stomach, slender fingers teasing across her dreamself’s attire. Clad only in a bright yellow swimsuit, the solar princess cut a figure that any straight-minded stallion would have popped a boner at; even from her own awkward position, Luna felt a light fluttering in her stomach as she watched Celestia’s fingers trail lazily across her filled-out, snow-white thigh.

Despite her sister’s sensual appearance—which, Luna admitted, wasn’t really anything new—the scene itself was actually quite relaxing. She’d peeked in on the dreams of ponies with stresses or frustrations before, and the pull of a tranquil environment was actually quite common. Thus far, there was nothing here that might have suggested that Celestia’s dreaming mind was interested in anything other than...well, relaxing.

At least she didn’t seem to be aware of Luna’s presence. Given the rather serene nature of the setting, though, she’d have to take care that her sister didn’t notice her.

Luna’s eyebrows went up as her sister opened her eyes and leaned forward. As if Celestia had been able to read Luna’s mind, her eyes darted from side to side, as if to make sure that nopony was watching her. Luna shrank back further into the bush, the branches rustling quietly as she concealed herself further. Meanwhile, Celestia appeared to decide that she was alone enough for now and reached behind her beach chair, pulling something out of a bag and settling it onto her lap.

Luna squinted. The item appeared to be… Hm. A balloon. It was a big red one: plump and tall, around the size of her head. As she watched, Celestia began to squish it between her fingers. A blush played across her cheeks as she squeezed the balloon’s bottom, forcing more air toward the top and expanding it until it swelled to nearly half again its original size.

Why in Equestria would Celestia be dreaming about this? And why would she be blushing over it? Frowning, Luna continued to watch.

After a minute or so of fondling the balloon, a shadow passed across Celestia’s face. Once more, she glanced around to make sure that the area was otherwise empty. Her isolation secured, she turned back to the balloon and smiled. Luna blinked. She knew that smile. It looked nearly...lustful.

Celestia took a deep breath, tensed her biceps, and pulled the balloon into her chest. Each one of her sizeable breasts—as befitting a princess of her stature—was an E-cup, around a third of the size of the balloon. As Luna watched, though, Celestia pushed the balloon deep into her cleavage, her breasts nudging into place on either side of the balloon and squeezing it tight.

A blush covered Luna’s own face as she realized what she was watching. She was clearly intruding upon something very sensual—sexual, even—and in the privacy of Celestia’s own dreams, nonetheless. Still, she couldn’t help but remember days gone past—days before the Nightmare—when Celestia’s bed had been her own as well. Still hiding, she settled in and continued to watch.

On and on Celestia pushed the balloon into her bust, the exterior distorting and swelling, squishing between her cleavage until it could give no more. And then—it popped, exploding against her swimsuit-covered breasts.

A long, low exhale escaped Celestia as her chest began to swell. Luna’s eyes widened, watching Celestia’s bust get bigger—and bigger, and bigger, and bigger. At first, the growth was nearly imperceptible, but by the time she’d finished, it was clear that her even more sizeable jugs were straining against what had already been a rather tight top. Each breast looked to be just over half the size of the original balloon now, if not a bit bigger.

Celestia wasted no time to bask in her new size, though. Without spending a second to revel in her new bust, she reached behind her chair—her shifting shoulders pushing her big tits to bulge even more obscenely against the fabric of her swimsuit’s top—and retrieved a second balloon, around the same size of the first. This one, too, found itself squeezed between the solar princess’ cleavage, sinking even deeper between Celestia’s royal boobs, and popping as she squeezed it beyond all containment.

This time, Celestia moaned aloud as the growth took hold. Her breasts pushed out more and more, filling out as the size of the balloon fled into them. Her bust now hung heavily over her torso, a good three inches of cleavage showing above her neckline. Both her nipples—obviously erect, and larger than Luna had ever seen—poked past a massive pair of tits that had to be at least an H-cup, if not even larger.

Luna’s blush deepened. Her sister was obviously very much enjoying herself. Pausing between balloons—from what she could make out of the bag beside the lawn chair, there were still quite a few more to go—Celestia took her bust in her hands and squeezed. Another moan escaped her, long and throaty, as she kneaded her massive breasts like dough, her fingers squeezing oodles of titflesh and fondling her thoroughly erect nipples.

It seemed, though, that her breasts weren’t the only thing that Celestia was interested in, though. Once she’d finished fondling herself, Celestia’s next balloon found itself hovering over her crotch. Luna watched, the space between her thighs growing hotter and wetter as Celestia rubbed the balloon against her cameltoe. The rubber surface depressed against what could only be her sister’s marehood, and exploded with a sharp pop! when Celestia closed her thighs around it.

Celestia’s head actually went back, her whole body going erect as the growth started. This time, it appeared to be centralized to her crotch. Still masturbating fervently through her swimsuit—though now with her fingers instead of the balloon—Celestia groaned, her marehood’s lips swelling in size. Luna watched in amazement as a simply massive cameltoe began to press against the bottom of Celestia’s swimsuit, its lips puffy and obviously aching with need.

That wasn’t the only thing that was growing though. Luna had to cross her legs to try and stop her own arousal as Celestia’s thighs began to grow as well. They’d already been filled out nicely, but now they pushed out even more. In a few seconds, all semblance of a thigh gap had vanished. Celestia grunted happily, still rubbing against her bulging clit as her fat thighflesh closed in around the sides of her hand, pinning it in place.

But that didn’t appear to be all. Keeping her right hand firmly positioned between her nice, thick legs—and, presumably, right up against her aching marehood—Celestia used her left to snag another balloon from her bag. She eyed it teasingly for a second, then said,

“Oh, I know just where to put you.”

Luna’s eyes widened as she watched Celestia shift her weight to one side—her prodigous thigh and titflesh jiggling massively as she did so—and press the balloon up again her pleasingly curved rump. As far as flanks went, it filled out her bathing suit nicely: two big, round cheeks that couldn’t possibly have been more spankable or squeezable. But for Celestia, it seemed, they weren’t enough.

Celestia wasted little time on this balloon, instead opting to sit down directly over it, popping it with the weight of her ass. Luna stared, her mouth going dry, as her sister’s rump began to expand as well. Her asscheeks plumped up further, spreading up and out, and pushing their owner a few inches up like a soft pillow. Celestia just shifted in her seat, squishing her new, larger rear happily. She returned to kneading her breasts, moaning cutely as her ass filled out her chair entirely, each cheek pressing against one of the armrests.

Luna’s breaths were getting shorter now. She hadn’t been this turned on in—well, a millennium. A bead of sweat dripped down her forehead. Her hand crept toward her own crotch. This was hotter than any dream she’d had in months. To view her sister as this pure, sexual creature—to view the size that she dreamt of!

It was nearly overwhelming.

Celestia took a moment to admire herself. She took a big handful of assflesh, which was now spilling out around the edges of her swimsuit, and squeezed it. She shuddered with visible pleasure as her bountiful rear bounced and jiggled like jello. Her other hand wandered up to one of her erect nipples, which sat on a breast that weighed down to her sculpted stomach, and gave it a sensual tweak. Her head jerked back, her body going erect with arousal. Luna could actually see her sister’s swollen lips straining against the fabric over her crotch, their fat, puffy forms staining the swimsuit with her warm, damp secretions.

After a few moments of playing with herself, though, something shifted in Celestia’s posture. She let her hands fall to her sides—her fingers still absent-mindedly dancing across her ample thighs—and glanced around her. No longer did she look wary, though, fearful of another discovering her secret desires. No—that wasn’t shame in her eyes. It was...hope?

It was hope, Luna realized, desire, wishfulness. Celestia looked almost disappointed that she couldn’t see anypony else. Luna nearly stepped out of the bushes herself to greet her before realizing what, exactly, Celestia wanted.

She had the body of her dreams—literally. Curvaceous, feminine, and bountiful beyond a normal mare’s wildest fantasies—but nopony to share it with. Of course, Luna realized. What use did Celestia have for her new size if there was nopony to see it? Nopony to admire her—to worship her—to have, she added, blushing again, any “fun” with?

Well, she couldn’t have that. Celestia, all big and sexy and alone in her own dream? That wouldn’t do. Had she waited a bit longer, it was doubtless that another pony—a dream projection, really, but a pony all the same—would have appeared to enjoy Celestia’s new body, but Luna was impatient. And besides, she decided, a smile growing on her face, she wanted to see the reaction of one of her sister’s real subjects to this form.

Casting her mental awareness out into the larger dreampool was as easy as breathing. Luna’s consciousness darted between a few dream bubbles, peeking in and around each one, until she found one that was suitable. Then, as she settled back into her dreamself’s body, she pulled that pony’s mind along with her, yanking her out of her own dream and into her sister’s.

After all, Luna decided with a smug look on her face, what better subject for a cross-pollinated dream than a pony who’d been dreaming of a generous Princess Celestia anyway?

Sumi was pulled out of her dream softly, sliding out of it and slipping into the new one. Still, it was still something of a shock to her when the Canterlot Palace’s ballroom vanished around her, a garden and swimming pool shimmering into existence to replace them. Clad only a tight pair of panties and a bra, the first thing she noticed was the slight breeze brushing against her bare stomach. She stiffened, shivering.

The second thing she noticed was—well, her. Sumi’s mouth went dry, her gaze slowly drifting up as she took in the full figure of the pony standing across from her.

“Why, hello,” Princess Celestia said. “Now, how did you get here?”

For a moment, the Princess looked actually somewhat shocked. Then, a look of pleased surprise slipped over her features instead, and she turned to face the newcomer.

Sumi felt frozen in place. She was powerless to escape, or even to move, as Princess Celestia took a long, lazy step toward her, then another. As an alicorn, the Princess’ body always commanded a certain amount of attention, but she had filled out even further past what Sumi had just been dreaming of. Her huge, heavy tits hung down toward her stomach, their generous flesh bouncing with every step the princess took.

Sumi’s pupils dilated, her breath catching in her chest as she caught sight of the Princess’ enormous ass, the sides of which stuck out past her wide-set hips. It oozed past a swimsuit that just barely contained her bulk, wobbling with the slightest breath.

“This is a private party, my little pony,” Celestia said. Her matronly, dulcet tones were nearly musical to Sumi’s ears, a comforting, familiar sound that held a hint of sultry promises. She’d closed about half the distance between them now, and Sumi felt as stiff as a block of granite. Part of her mind was screaming at her to run—Princess Celestia was actually noticing her!—and the other part was screaming at her to stay, stay, stay. “And you’re not even dressed for the occasion.”

“I—” Sumi swallowed, free from Princess Celestia’s spell for an instant. She glanced down at herself. Her eyes widened when she remembered her garb. Oh, gods. What would—did—Princess Celestia think? How could she be wearing this? Why would she be wearing this? She tried to remember, but the last dream was already slipping out of her memory.

“It’s no trouble.” Celestia came to a stop, her swaying hips falling into place slightly to her side. She placed a hand upon her ample hip, and peered down at the smaller mare. With a tremor in her gut, Sumi realized that the Princess was just inches away. “Simply...unexpected.”

A shiver went down Sumi’s spine as Celestia slipped a long, smooth arm over her shoulder and around her waist. “Although,” Celestia said, hanging onto the word. Her fingers curled around Sumi’s side, pulling her in closer until her forehead was smushed against Celestia’s ample bust. “You’re not quite dressed for the occasion.”

Sumi shuddered with pleasure as Celestia’s breasts smushed against her forehead, then jolted awake as she felt her clothes…changing. Eyes wide, she glanced down at herself. “A...swimsuit?” she asked.

Celestia smiled warmly down at her. “What better attire for a poolside encounter?” she asked. She waved her fingers lazily in the direction of the pool.

“Now,” Princess Celestia said, gripping Sumi a little tighter. With a gasp, Sumi felt herself being PULLED up into the air, the princess grasping her tight around the hips and heaving her up until they were eye to eye. Celestia smiled at her, that knowing, motherly face contrasting with the mischievous glint in her eye. “That’s much better, isn’t it?”

“Oh! Y-yes.” Sumi blushed, then gasped when she felt Celestia squeeze her against her bust. From her place in the bushes, Luna’s eyes widened as she saw her sister pulling the new mare

against her chest. Celestia’s massive breasts, each one about as wide as Sumi and straining against the fabric of her swimsuit, folded over the helpless—though certainly not unhappy—mare’s torso.

Just as she’d been smothered between gallons of warm, jiggling titflesh, Sumi found a warm pair of lips against her own. Celestia pulled her into the kiss, seized her, overpowering her with pure size and sexuality as Sumi melted into her embrace.

Luna was the first one to notice it. She gave a start as she saw the new mare’s belly begin to puff out. At first, it was almost unnoticeable, given that it was right below Celestia’s heaving jugs. Soon, though, it became undeniable: Sumi’s gut was slowly expanding, growing wider with every second.

Sumi let out a muffled moan as she realized what was happening. Celestia wasn’t just kissing here anymore—she was breathing into her. Each puff of her breath forced more air into Sumi’s mouth, down her throat, and into her swelling belly. Sumi moaned again, squirming against Celestia’s heaving chest, as her gut rounded out, pushing her away from the princess’ toned stomach.

She expanded more and more, Celestia slowly, but steadily giving her figure more and more air. Soon, Sumi was groaning, her belly filling up to the point where it was actually pushing her away from Celestia’s embrace. It continued to grow, swelling with air as Celestia’s motherly hands stroked across her rump, squeezing her also-expanding Cutie Marks as more and more air filled her body. Her swimsuit became overstretched, like Celestia’s, but differently—instead of several different places, it was expanding all over, small rips and tears appearing as her body blew up to ever-increasing sizes.

In no time at all, Sumi’s body had blown up like a balloon, her belly passing the size of Celestia’s now J-cup breasts. Oodles of titflesh folded over her big, swollen belly, jiggling boobs resting comfortably on a big, taut gut as Sumi blew up bigger and bigger.

Sumi groaned, still lost in Celestia’s kiss, imprisoned. Her legs were pushing back from the rest of her body, her belly pushing further away from Celestia’s own as she approached a spherical size. Celestia just kept blowing her up, inflating her past any reasonable size until Sumi resembled nothing less than a giant balloon. More and more of Sumi’s new swimsuit was stretching, tearing, splitting along the seams as oodles of her overswollen flesh poked through.

Off to the side, Luna was panting. Her fingers were planted firmly between her legs, her aching marehood crying out for more stimulation, more attention to equal the hotness of the fantastic scene unfolding in front of her. A thin sheen of sweat covered her forehead; as she went to wipe it away, she paused, staring out at the pair across the pool. Celestia was growing again.

Celestia groaned into the kiss, her tongue worming its way into Sumi’s mouth as she took a momentary break from inflating the “smaller” mare bigger. Now nearly two-thirds as wide as Celestia was tall, and almost perfectly spherical, Sumi found herself bouncing lightly against Celestia’s side, her coat stretched rubber-thin over the belly that had rapidly come to encompass most of her body.

Meanwhile, Sumi’s “balloon” body seemed to be having a similar effect on Celestia’s figure as the balloons from before. Luna watched in fascination as Celestia’s whole figure began to expand together: her ass widened, wobbling with new mass; her hips and thighs thickened, creamy white flesh becoming ever more succulent; her massive breasts became even more so, her chest heaving lightly as her tits grew down to reach her stomach—and beyond.

With a loud ri-i-i-ip, Celestia’s swimsuit tore—in two places at once. It split right down the seam of her right thigh, oodles of generous white assflesh poking through the rips and tears. Then it just split right open across her oversized cleavage, a canyon of space between her boobs showing through. Celestia spared but a moment to eye her new assets, then turned back to her victim, who was still wobbling helplessly against her.

That was all too much for Luna to take. She couldn’t bear waiting any longer. Her arousal was too high, her need too intense. No longer content to be merely a watcher, she pushed the branches aside to make room. As she stepped out into the open, her clothing ripples, a swimsuit of her own rippling into existence over her form.

Celestia’s head jerked to face her. “Ah—Luna!” Her eyes wide, she took a moment to collect herself before continuing. “You’re here, too?”

“Of course,” Luna said. She smiled at her sister, stepping forward. Each step that she took past the pool, she molded her dreamself’s form further. Every step, every breath infused her figure with a bit of size, expanding to match Celestia’s. “I couldn’t let you have all of the fun.”

She groaned, low and throatily, as her boobs and ass grew to half the size of her sister’s. She’d experimented in dreams before, yes, but nothing like this. The size, the weight, the incredible tightness of the swimsuit against her body—it was incredible. By the time she’d closed half the distance to the pair of lovers on the other side, she’d already swelled to an H-cup, with a massive, wobbling ass full of weight and power.

“Mm.” Celestia nodded approvingly. She licked her lips as Luna approached eyeing her sister’s voluptuous form. Small rips, similar to those on her own swimsuit, were beginning to erupt across Luna’s new clothes, letting bits of her deep blue coat poke through. A good six inches of cleavage showed above the neckline of her swimsuit, exposing the tops of a truly massive pair of breasts matched only by Celestia’s own. “You’ve filled out, Luna.”

“It seemed the popular thing to do.” Luna smiled as she stepped just across from Celestia, with Sumi still bobbing helplessly in between them. She wasn’t quite Celestia’s size yet—Celestia still had a good four inches of height on her, and her breasts hung nearly half again as low over her stomach. Her thighs, too, had nothing on Celestia’s tree trunk-sized legs, which looked as though they could easily crush a pony between them.

Luna’s ass, though, was the clear victor: a massive mound of wobbling flank that jiggled with even the slightest breath. It jutted out behind her slender waist by a good eight inches, a pair of perfectly globular spheres that looked more spankable and squeezeable than likely any pony’s in Equestria.

Luna groaned as her chest swelled further, her neckline splitting right down the middle and letting her massive breasts pop free. “This size feels so good,” she murmured, exploring her new body with both hands. “Is this truly what you dream of, sister?”

“Dream of—this is a dream?” Celestia said, startling.

“But of course.” Luna smiled knowingly. “You have excellent taste in fantasies, sister. I may have to pick this one up for myself.” She flicked a finger across her ass and shivered while her magnificent rear wobbled like jello.

“A dream,” Celestia murmured. She glanced around her, then down at her massive chest. She chuckled. “It makes enough sense. It’s a welcome fantasy, I suppose.”

“It is indeed.” Luna’s hands roamed across Sumi’s inflated form, and the spherical pony tingled with pleasure. “And what is a fantasy for, but for pleasure?”

Celestia smiled back. “My thoughts exactly.”

Both princesses glanced down at their helpless prisoner. Sumi squirmed against Celestia’s bust. Then, as one, the two alicorns took hold of Sumi’s ballooning form and raised her to their mouths.

Sumi again found herself melting into Celestia’s air-breathing kiss—and then shuddered, a tingle going down her spine as Luna’s luscious lips made contact with her own lower, puffy lips. Stretched wide between her ineffectually wiggling legs, Sumi was powerless to do anything but pant and groan as the two princesses pushed more and more into her, Celestia from her front, and Luna teasing her from the back.

Luna savored the struggles of the spherical mare, savored her obvious and mounting pleasure. She attacked Sumi’s marehood with her lips and tongue, delving deep inside of her as she helped Celestia blow her up bigger and bigger and bigger. Stretched to its absolute maximum, Sumi’s swimsuit ballooned up to a maximum size—before exploding off of her with the snapping of overstretched latex.

Sumi squirmed, writhing with impossible pleasure as Celestia’s lips mashed against her own. Her belly was so big—huge, even, nearly touching the ground now as she blew up bigger and bigger. Her pleasure mounted as Luna continued to tease her aching pussy, blowing more and more air into her womb and gut alike until her limbs had nearly completely receded into her massive, swollen belly.

She whimpered, feeling so tight, so full of air. She could feel her very coat straining, squeaking as it struggled to keep what had to be hundreds of gallons of warm air inside of her. Celestia kept kissing her, though, pushing more and more air inside of her until Sumi felt she was ready to pop.

And then she did.

With a sound like a thunderclap, Sumi simply burst, her overinflated body unable to take anymore. She burst apart like her swimsuit, all the air that had been pumped inside of her exploding out of her at the exact same instant that her orgasm hit, a riding, crashing wave that only exacerbated that incredible pleasure of popping. In her last moment of lucid thought, before bursting free of the dream, Sumi felt a single, searing sensation of hot, searing pleasure, lancing through her body with an intensity clearer than any pain she’d ever felt.

And then she was gone, zapped from the dream and back into her own.

Luna exhaled slowly, a shiver going up her spine as her own arousal reached a peak. She’d rarely seen such an erotic thing in any dreams she’d intruded on before. She suspected that Celestia had given her a new kink—and, admittedly, she didn’t quite mind.

She was lost enough in her own thoughts that she startled when Celestia placed a finger on her breast. Celestia’s fingers sank deep into Luna’s plump titflesh, the mass of Luna’s bust spilling out past her torn swimsuit. Celestia met her sister’s eyes and smiled mischievously.

“You may have made this dream a bit more exciting,” Celestia said, something twinkling in her eyes. “But I haven’t forgotten that you intruded in the first place.”

“Sister, I—” But Luna found herself cut off as Celestia pulled her against her breast. Their oversized chests squished together, erect nipples the size of thumbs rubbing against one another as their owners kissed. Luna took Celestia’s lips hungrily in her own, exploring her sister’s mouth with her tongue. She felt her breath growing shorter, her thighs becoming hotter and moister as her arousal reached unimaginable peaks.

Yes. This was what she had missed. This was what had been lacking. She needed to feel her sister like this, pressed up against her, big and warm and so soft as to swallow her up. Luna groaned into the kiss, letting her sister’s mash against hers, so lost in the sensation that she almost didn’t notice when Celestia began to exhale into her.

But by the time she’d noticed, it was too late. Luna’s eyes opened wide, but she was powerless—overcome both by her sister’s size and her own flood of arousal—to stop her sister’s efforts to inflate her. Much like Sumi had, Luna soon found her skin growing tight, her coat over her belly becoming taut and thin as it expanded like a balloon.

Celestia’s cheeks puffed out again and again, forcing more air down Luna’s throat and pushing her to larger and larger sizes. In what felt like no time at all, Luna’s stomach was resting directly on the ground, the rest of her limbs waggling helplessly in the air as her belly blimped up above the rest of her. Her swimsuit had long since exploded off of her expanding, rounded form, leaving her massive, heaving breasts free to the warm poolside air along with her sopping, warm clit.

Celestia finished the kiss in earnest, her lips coming off of her sister’s with a wet pop. Before her, Luna just groaned, feeling impossibly, incredibly full. She felt so tight, so massive, her whole body having swollen up to nearly ten feet in diameter. And so round. She felt like one of her hooves would have bounced off of her belly like a drum, had she been able to do more than wiggle it.

Celestia just planted her hands on her hips—which, in turn, had become only more ample as she’d rubbed against Luna’s ballooning form. By now, she was simply a goddess of size, her ass protruding far behind her, her magnificent breasts easily each the size of her torso, and her thighs wide, thick, and creamy. Luna whimpered, eyeing her sister’s form with unbridled lust.

Princess Celestia eyed her sister’s inflated form with approval. “Much better,” she said, her matronly voice warm and comforting in Luna’s ears. “Now, given our present location…”

Luna’s eyes widened as Celestia planted her palms against her side and slowly began to roll her. Luna’s massive, blimped-up form rolled over the ground easily, though some slight bumps bounced her light, ballooned figure a few inches into the air. “Sister!” she gasped. “What are you doing?”

“Just making use of a new toy,” Celestia said. “Don’t mind me. Aha!”

Luna yelped as Celestia shoved her off of the side of the pool—and grunted as her massive, round backside hit the surface. She then moaned, her tiny limbs waving helplessly as she sank into, then bobbed across the top of the warm, gentle water.

A smile on her face, Celestia heaved herself onto Luna’s floating form, clambering to the top of her belly. She spread herself out on Luna’s gut, lounging on the massive form of her inflated younger sister.

“Ah,” Celestia said, spreading her oversized body out beneath the bright sunlight. “Now this is a lovely dream.”

She paused, then glanced back over her shoulder. “You know,” she said, casually. “I really do have to thank you, Luna.”

“What for?” Luna asked, forcing the words out between a pair of chubby cheeks.

A sultry smile crossed Celestia’s face. “Why,” she said, “for showing me how wonderful my younger sister can be.” She stroked Luna’s belly, savoring the tautness of her coat. “And reminding me of how...attractive you are. It really has been too long.”

“We agree on that, then,” Luna said. “I must confess, half the reason I intruded upon your dream was to try and...rekindle something like that.”

“Good,” Celestia said, nodding. She patted Luna’s belly, then snuggled into it. “Shall we do this again sometime, then?”

Luna didn’t even have to think about it. “Oh, yes,” she said. “Absolutely.”

“Good.” Celestia hummed thoughtfully to herself for a minute. Then, “Perhaps we should invite that nice young mare to join us again. She seemed rather nice.”

“Ah. Yes,” Luna said, chuckling. “About her…”

When Sumi awoke next morning, she could hear birds chirping outside of her window. She smiled to herself, feeling warm and comfortable in her bed. That had been a nice dream. It might even be her new favorite.

She opened her eyes blearily, yawned, and reached up to rub the sleep out of her eyes—and found she couldn’t. Sumi’s eyes shot open wide, and she snapped awake.

The first thing she noticed was the big, white-furred mountain rising up above her face. Her eyes widening even more, Sumi gaped, and tried to reach up toward it. She quickly found she only just barely wrap her arms around it—it was much too big, much too round, to even hold it completely.

It was her belly—or at least, appeared to be. Sumi gaped at it, her jaw dropping as she remembered her dream. She grunted, her arms waggling and managing to get just enough traction against the mattress to push herself off and out of bed.

She hit the carpeted floor, not with a thud, but with a squeak, her big, inflated body bouncing a half-inch off of the ground. Sumi let out a high-pitched “oof” as her bloated belly trembled. It didn’t even hurt, though—her bigger, softer, inflated ass caught most of the impact. Her eyes wide, Sumi did her best to gaze down at her stomach and found that she could only see half of it. The rest was hidden beneath her now-massive bust, complete with a pair of tits, each bigger than her head, resting comfortably on her bloated, swollen belly. Groaning at her new size and weight, she managed to pick herself up and make it over to her dresser.

Sumi glanced mournfully down at her massive gut. It stuck out in front of her by more than a foot—almost two. It might’ve been filled with anything—air, water, food—but whatever had caused it, it wasn’t about to fit into any of her standard t-shirts anytime soon. And those breasts. Sumi shivered as a gust of air swept in through the window and across her erect, bare nipples. They felt impossibly tender and sensitive.

She eyed her dresser for a moment. There was something there—an envelope, addressed to her. Sumi’s eyes widened; with only some difficulty, she managed to pick it up while balancing the weights of her newly massive ass and belly.. Reading it was a little bit easier, once she sat back down on her bed, her flank squishing about beneath her as her breasts jiggled alluringly. As she noted the royal seal on the back of the letter, a shiver went down her spine, and something hot teased the space between her legs.

Miss Sumica, the letter said, addressing her directly. We thank you for your participation in last night’s events. However, we must apologize for any inconvenience caused by said participation. Dream-magic has a tendency to leave lingering effects on the bodies of non-alicorns, and for that, we are quite sorry.

Sumi’s eyes darted down to her blimped-out form. She almost choked. Wait—so it hadn’t been a dream? She glanced down at the signature, freezing when she recognized the names. Was this even possible? What was going on?

Should you wish, however, you are warmly invited to visit Canterlot Castle for assistance in the location and/or purchase of a new, suitable wardrobe. Afterwards, or instead, you are more than welcome to “play” with us again, either in the waking world, or in dreams.

It was signed, with a flourish:

Princess Celestia

Princess Luna

Sumi just stared at it for a moment. Then, taking a deep breath, she let the note flutter to the ground. She managed to scootch herself over to the open window with only minor difficulty this time.

In the distance, above the rooftops, the proud spires of Canterlot Castle towered above the rest of the city. A soft, yet still disbelieving smile played across Sumi’s face as she eyed it for a few moments.

“Well, then,” she said, sighing. She patted her oversized belly and grinned. “Looks like I’m going to have to lumber on up there, huh?”

She was looking forward to it.
