Those Aren't Beach Balls...
Yvette set her things down, drew a metered breath, and closed her eyes. There was no way in Tartarus that anybody could see her within the confines of the changing stall, yet that did little to still her fluttering heart. Peeking down at her shoulder bag, knowing exactly the contents of her satchel, her plans had all but come to fruition.
She knew full well that social growth was often an uncomfortable process and, therefore, she’d decided to broaden her horizons and push herself. Normally a bit of a shut in, Yvette was more than content to curl up with a good book in her free time. She didn’t necessarily want to become a spinster, yet she’d never really felt comfortable going out - as such, in a fit of pique, she’d concocted a bold scheme and made a rather brazen purchase for herself.
Ordinarily speaking, the most risqué articles of clothing in her wardrobe consisted of pieces such as a skirt that only came down to her knees, or a sheer top which often showed off her darker bras. Standing head and shoulders above most ponies made her stand out like a sore thumb, so doing anything to ensure she doesn’t draw any additional attention to herself tended to suit her needs. Unfortunately, her predilection to modesty did have a fair number of drawbacks.
Being a nerdy little recluse wasn’t all that bad, although there was one thing she’d always pined to do. Despite living a short walk from the beach, she hadn’t gone to sun herself since she was but a mere hatchling; it was a crying shame, since ponies came from all across Equestria to enjoy the cool, refreshing waters of the nearby surf. Ever since she had acquired her current home, she was often reminded of the relaxation she was missing out on. However, on one particularly sunny afternoon, barely even a week prior, she’d reached her tipping point.
Whilst reading an article on how to better one’s self, in a Mare’s Quarterly magazine, she stumbled upon an advert for mail-order bikinis from Rarity’s Secret. Available in a wide variety of options and more sizes than she even thought possible, the swimwear immediately caught her eye. Considering she did have a few spare bits on hand, and she wouldn’t be required to go out to a clothing store, she threw her inhibitions to the wind, filled out an order, and dropped it in the post.
Nought but three days after mailing off the purchase form and a cheque, she received a small and rather unassuming package at her doorstep. She brought the parcel inside, taking care to lock her door and draw her blinds. Opening the box, which was plain, matte-white cardboard - save for the faintly-embossed Rarity’s Secret logo, she marvelled at the garment; the two-piece bikini was everything that she’d hoped for, if not markedly more provocative than any other garment she owned. Additionally, the sarong paired that was paired with it - a freebie thrown in since it was her first order - complimented the actual swimwear rather nicely.
Hastily assuring the sizing was right, and motivated by the impulse to enact her plan, Yvette gathered up her things and trotted off towards the beach. She knew she’d have to strike while the iron was hot, lest she concoct an excuse to not go on the adventurous outing, so she did just that. Strolling beneath the mid-morning sun and savouring the warmth of its summer rays, it only took her a few minutes to reach her destination. One regrettable thing about the beach was just how popular it was. She’d been in one of the public changing rooms for less than a minute, before someone tried the door-handle.
“J...just a minute!” she shouted, instinctively adjusting her oversized spectacles.
Realizing that she couldn’t dally forever, she levitated her glasses off, and slipped the sundress up and over her head. Getting undressed was easy enough, although donning her new outfit would prove much, much more of a challenge. Digging the two-piece out of her bag, and taking a moment to orient the articles, she decided to start with the top.
Both pieces of the garment had long, somewhat elastic strings which needed to be tied together; it wasn’t a horrible inconvenience, though she’d never had to worry about specifics like knots before. Having reached behind herself and secured the top around her back, she covered her loins and rear with the bottom, fastened the strands on either side around her waist, and turned to inspect herself.
Her reflection peered back at her. Covered in a deep green, near-black hide - save for the various hues of green for her carapace, elytra, and crest, she was just as tall and slender as ever. From behind her huge, admittedly dorky glasses, she squinted at herself; in spite of being in total seclusion, a light green blush crept onto her cheeks. The outfit complimented her aesthetic well, almost too well, to the extent where seeing herself in it sent her heart racing.
The bikini fit her perfectly. It covered enough of her to be modest, but still revealed enough to put her out of her comfort zone. The light turquoise of the fabric - adorned with a very simple floral swirl pattern - accented her dark hide and complimented her eyes, whilst still safely and securely covering her mare bits. Peering down at her chest and readjusting her top, she scrunched her snout. Even though the article did restrain and fully cover all her naughty bits, her blush grew stronger. It was honestly the first time in memory that she’d been out of her home wearing so little.
Afterwards came the sarong; being the largest piece of her outfit by far, Yvette unfolded it and tied it around her waist. The relatively plain, translucent, lime-green sheet of fabric - a perfect match for her dorsal fin and relatively short tail, fit in well with the rest of her beachwear. Though it did almost nothing to obscure what lay behind it, the veritably skirt-like piece made her outfit feel all the more complete; finally seeing herself in her entire ensemble made her as happy as a hatchling!
Watching her reflection, she slowly turned in place, taking it all in. For all intents and purposes, she had nothing to worry about; in spite of her remarkable height, she was a conventionally attractive changeling - a bit on the thin side, sure, but she was hardly an eyesore. She was only barely scraping the two-hundred pound mark, which was remarkably light as far as changelings her size were concerned.
Equipped with a relatively modest bust and rather shapely behind for someone of her slender stature, as well as a finish on her elytra that could make just about any changeling jealous, her reasonable mind assured her that she had little to worry about - still, her rational thought struggled against her inhibitions.
“Are you almost done in there?” a voice called, causing her to start.
Stuffing her dress and undergarments into her bag and reequipping her spectacles, she levitated her effects, told herself that everything would be fine, and saw herself out. A young stallion stood just outside the doorway, idly waiting for his turn to rinse off and change, though her appearance apparently caught him completely off guard. The lad’s mouth went agape, as his gaze drifted over her slender form.
Though Yvette had intended to saunter to the beach and find a place for herself, finding herself unabashedly eyed up by the youth gave her a moment for pause. His reaction to her, whilst certainly flattering, was the last thing she’d hoped for. It was only when she noticed a twitch within his trunks did her composure break, sending her scampering away - almost literally on all-fours.
Fortunately, the lad was either too shocked or enthralled to follow her. Cresting a dune, with her goods hovering along beside herself, the rolling waves came into view. Given that it was a weekday, the beach wasn’t too heavily populated. A number of families relaxed by or played in the surf, while a few seniors combed the sand for shells or discarded treasure. It was a decidedly relaxed scene - which she was thankful for - though she still had to find a place for herself.
Scanning the seaside, she lazily walked onto the sand. There was plenty of space available, although she’d prefer to find a spot well away from any potential voyeurs. Proceeding towards a relatively secluded area, some distance from the entryway to the beach itself, she sank her umbrella into the sand and began to settle in. The soft sounds of rolling waves and gulls soothed her frayed nerves, while she unfurled her oversized towel and eased herself down.
Seated under the shade of her parasol, she sat her bag down and rifled about for her book. Seeing as how people watching or swimming were two of the more popular activities for lounging by the seaside - both activities she had little interest in, she’d brought a grimoire to occupy herself. Cracking open the small tome, she laid back and contentedly sighed - that was, until a blinding light struck her face.
Sadly, the umbrella was unable to shield all of her from the sun’s rays, which were made worse due to her glasses. Pushing herself up, she sat her copy of Mothra's Methods of Magic, Vol. II by her side, and rummaged around in her satchel. She’d brought a number of supplies for herself, having prepared as thoroughly as possible, and she had just the thing. As her fingers wrapped around a small plastic bottle, she removed her hand.
Even if she had been fully shielded from the warm rays, bringing some sun tan lotion was a must. The last thing she wanted was to have her day ruined by the tender, crisp hide of sun-burnt chitin! Flipping the bottle’s cap and squirting a generous dollop of the creamy substance into her palm, she quickly looked around for any prying eyes; from what she’d read, watching a girl anoint herself at the beach was a rather infamous pastime for perverts. With the coast clear, she rubbed her hands together and began covering her legs with the balm.
Methodically working the lotion into her chitin, and taking care not to miss any areas, she worked her way up her calves to her thighs. Since the sun’s ceaseless march stopped for no mare - or changeling, for that matter, she saw little point in selectively covering herself. She rolled slightly to one side, and then the other, applying the salve to her mostly covered backside as she did so. Her head and crest were next; the translucent membrane that sat between her ridge-spines was surprisingly sensitive to being burnt if she wasn’t careful enough - a sign that changelings were never meant to stay out in the sun undisguised for too long.
Her arms, abdomen, and upper chest immediately followed suit, although she quickly hit a snag. With only a slender band that tapered off into some strings securing her top, her back was almost entirely exposed. She was woefully ill prepared for the situation, having failed to account for lotioning between her shoulder blades, which left her in a bit of a pickle. Staring down at the bottle, completely forgetting that she could alter the length of her arms, a shadow appeared out of the corner of her eye.
Twisting to the side, she peered upwards and froze. Her rather oblivious ostentation had already caught the eye of a friendly bystander; looming above her, backlit by the sun, stood a comparatively short, relatively curvy unicorn. She squinted up at her uninvited guest, confused as to why she was being bothered, but her unasked question was addressed all too quickly. Attempting to interject, as the pony pointed down to the bottle of sunscreen, her reaction came a split second too late.
“Need a hand with that?” the mare asked, smiling down at her.
“Oh - uh - no, I’m fine,” Yvette replied, withdrawing her hand from behind herself.
Though she appreciated the offer, she couldn’t let some random mare nonchalantly rub lotion on her - even if said mare was kind of cute. Moving her free hand from behind her back, hoping to dismiss the kind offer, her thumb caught the knot fastening the bikini around herself. In one smooth, albeit wholly unplanned motion, her top became untied and started to slide free.
Seeing her guest’s eyes widen was the first sign that something was amiss, though it took her a moment to understand what had happened. Feeling the fabric cupping her bosoms loosen, slowly revealing her breasts, her hands flew to her chest. Mercifully, she’d just barely caught the infernal garment in time, but the damage was done. Turning her head, already feeling her cheeks darken, she up at the unicorn.
Though the mare hadn’t budged, her eyes were squarely glued to the changeling’s bust. Despite not having seen too much skin, the girl seemed entranced. A blush rested in her cheeks, she stood utterly motionless, there were two rather pronounced points on her chest which hadn’t been there before. As obvious as the physical signs of excitement were, for Yvette, the immaterial indicators were akin to a blinding flare.
Feeding on the affection of others was, much like one’s appetite, unique to the individual. Some could easily restrain themselves, effortlessly choosing when and under what circumstances they would consume, whilst others had a glaring lack of control. She, though she was loath to admit it, fell into the latter category. Simply being around creatures with affectionate thoughts or intentions for her was enough to provoke an involuntary response - a fact which she had failed to account for in this instance.
Propped on one arm, with the other holding the detached garment over her chest, she smiled sheepishly up at the pony. It was an awkward situation, one of which she’d had no way to account for, yet one which gradually escalated. She wasn’t fully aware of just how interested the mare was with her until her stomach grumbled; at that moment, realizing she was subconsciously devouring the ambient energy of her visitor, the real panic started to sink in.
“I...I’m fine, really,” she insisted, forcing an anxious and uneasy smile, the blush on her cheeks burning brighter with every passing second. “As much as I appreciate the offer, I can get it myself.”
A disappointed look crossed the unicorn’s face, before she nodded. “No worries,” she chuckled, turning and walking away. Strolling through the sand, only moving a handful of paces, she slowed and glanced back over her shoulder. “Absolutely love that swimsuit, by the way; it looks great on you!” She chirped, shooting the shapeshifter a rather suggestive wink.
Yvette’s heart skipped a beat, a thrilled shiver ran up her spine, and her dorsal fin perked up, yet those were a mere prelude of what came next. The compliment, paired with the barely contained licentious thoughts of the pony, was like a banquet. Every part of her tingled, from the tips of her hooves to the top of her head, as her body responded to the veritable feast.
While her form changed, responding to the energy she was inadvertently absorbing, the same couldn’t be said for her outfit. The strands tying her bikini to her, though they had some elastic quality, were only capable of so much. Contrasting against her hide, the colorful strands clung then sunk into her soft flesh. The subtle pinch of her seemingly-shrinking garment was yet another reminder that something was dreadfully amiss, spurring her to take action before things got worse.
Knowing what was coming, she flopped onto her stomach and reached both hands behind herself; in part to hold her bikini together, and also to force her elytra to stay closed so that she didn’t snap any of her clothing. Warm, comforting sensations flooded through her, filling her with a curious combination of excitement and dread. The strand securing the bottom of her two-piece bit into her waist, growing tighter with every passing second, while her chest progressively swelled. Yvette knew that ever since she’d first arrived, she’d become good friends with some of the locals, but she hadn’t realized that she appeared to be that friendly to some of them...
Cursing to herself, closing her eyes and shaking her head, she hastily tied and re-tied her top. Amorous attention or not, ensuring she didn’t have another wardrobe malfunction was of the utmost priority. With the bikini securely re-slung around her chest, she sat up, habitually adjusted her glasses, and examined herself. Despite the short-lived and relatively small influx of lascivious energy, the effects had been quite appreciable.
Her bust was easily a cup size larger than it had been less than ten minutes before. While they had been perky enough to stand on their own, the additional heft pulled them towards the earth. Knitting her brow, less than pleased with the development, she checked her lower half; sure enough, the rest of her had grown as well.
Her waist, thighs, and rump had all visibly thickened, giving her a bit of extra squish from the chest down. What was once her slight set of toned abs making up her belly bands was now a belly adorned by a small but soft coating of pudge; barely there, but just enough to noticeably stick out compared to before. Her lower half had undergone a similar change, filling out considerably, and she was certain that her rear jiggled more with every move she made. Most girls would have been mortified with the development, but the sight of her newfound soft curves left her feeling parched.
Back in the hive, before she’d even thought of signing up for the Changeling-Pony Interspecies Relations Program - something cooked up by Chrysalis and Celestia after the events caused by Thorax and a number of her fellow changelings - she’d often dreamt about glutting herself and growing large; it was a silly, childish fantasy, yet it had never failed to excite her. The idea of just letting herself take on and store as much licentious energy as possible; storing hundreds of pounds’ worth of love on her body, becoming bigger beyond belief, and still somehow wanting more, was enough to exhilarate her - sometimes a little too much.
Twisting her shoulders, trying to get a better look at her behind, she gasped. Through her sarong, she could see that the bottom of her suit, either due to her previous shifting about or the extra pounds she’d suddenly put on, had slipped from one cheek. She simply couldn’t leave one bountiful bun so perilously displayed for the masses, not after the two unfortunate incidents she’d already suffered through. Grunting in frustration, she got to her hooves and went to adjust her swimwear.
Tugging the fabric from the cleft of her tush, ensuring the bottom was properly adorned, she did what she could to peer at her backside. The sensation of being larger than usual was odd, but not unpleasantly so. Peering down at herself, savoring the exquisite view of her expansive cleavage, a silly grin split her muzzle. It was a shame she didn’t have a mirror to see just how big she was; she would have loved to have basked in the view...
A familiar shiver shot through her, wrenching her from her thoughts. Looking around, knowing that someone was enjoying her casual show, she spun in place. A small group of teens trotted by, casually chatting and joking among themselves, with three of them slipping her not-so-subtle glances. Two stallions and a mare, each doing their best to play it cool, occasionally glanced in her direction - specifically the direction of her bare flesh.
Keenly aware of just where their attention lay, she faltered. She could feel her dorsal fin start to stand up straighter than usual, not unlike the supposed wing-boners that some pegasi get. The primitive, predatory parts of her being seized hold, waging a pitched battle against her higher functions. She could have easily covered herself or possibly chastised them, yet a sudden compulsion gripped her. Extending her arms over her head, she leisurely stretched and averted her gaze.
It was a paradoxical moment; on one hand, she was immeasurably embarrassed that she was nonchalantly giving them a better look at herself - on the other, she basked in their silent adulation and unspoken desire. Peering down at the sand, she needed no assurance of their lusting. A wonderful feeling of contentment washed over her, akin to enjoying a fine meal, as she absorbed their mute adoration.
The sensation was intoxicating, both mentally and physically, and it stoked a ravenous flame within her. She knew she couldn’t give in, to let herself lose control to her inane hunger, but it was an uphill battle. Her kind simply weren’t designed for restraint, so her efforts were found wanting. Ignoring the struggling fabric, heedless of her increasing size, she threw her head back - though ensuring that she didn’t let her glasses fly off - and gently rocked her inflated chest back and forth, whilst at the same time slowly stroking her hands along her semi-rigid dorsal fin and seductively sticking her overly-long, lime-green, forked insectoid tongue out.
Caught in the moment, she was blissfully unaware of just how impactful the veneration was. Acting like a sponge, her metaphysical form gorged on the raw power emanating from her small audience, causing her physical form to change in response. Her breasts ballooned outwards, seemingly shrinking the size of her top, whilst her bottom suffered its own steady metamorphosis. With each passing moment, her bust gained another cup, slowly but surely making its way through the entire alphabet, and then some. Her previously slim and somewhat toned thighs, belly, and tush swelled considerably, storing the wellspring of power she was so unwittingly basking in.
She packed on the weight, and it went to all the right places; her onyx booty grew just as fast as her boobs did, and she went from looking like a moderately curvy fashion-model, to as though she had decided to shapeshift into one of those mares she had seen in an issue of a Play-Colt smut magazine. Her thighs had suffered the same fate, and the thigh gap that she had had previously was now nowhere to be found.
Her belly, not to be outpaced, did the same - going from a light layering of softness to a rounded-out potbelly for her now-mountainous mammaries to rest upon. It certainly complemented her big, beautiful look, yet it showed no signs of stopping. If it were any larger, it’d start to sag and cover up whatever fabric made up the front of her bikini bottoms.
As she continued to grow, the knots throughout her bikini slid, slowly but surely consuming all the remaining lengths of string until they could take no more; only then did they start taking out the slack. With as good of a time Yvette was having, she had no idea of the spectacle she was causing. Her thighs continued to swell outward, slowly losing more and more of the tone and definition they typically held, becoming like soft, marshmallow-like tree trunks. Above her lower limbs, eclipsing the sun, her backside cast an ever-growing shadow on the warm sands.
The twin, onyx globes of her tush were steadily revealed, as the swimsuit was engulfed betwixt her buns, and the sarong was pushed up and out of the way to make room. Even the largest bikinis would have struggled to contain the positively gargantuan globes that made up Yvette’s continually widening tush. As awe inspiring as the sight was - and some onlookers were in awe at the expanding changeling - her rear and legs were only two facets of her change. Her torso, much like her lower half, was changing at an uninterrupted rate.
Possibly the most dramatic change to overtake her expanding body was centered around her abdomen. Swelling in every direction, slowly draping over her hips, and burying the topmost section of her sarong - the knot of which was holding on for dear life - her stomach almost appeared to be the locus of her growth. The soft, supple flesh of her belly bands had lost nearly all definition, save for a crease which fell along its midpoint. One would have thought that such a slender and svelte changeling’s twisty-wisty buggo tummy stretchers wouldn’t have been capable of such a feat, but they’d have been dead wrong. The speed of her ripening paunch was only rivaled by what lay resting above it.
Her bosoms had become absolutely titanic; individually a number of times larger than her head, each breast rivaled your standard beach ball, albeit these ones were strapped down. Though it seemed impossible for her back to support the immeasurable weight of such an immense amount of tit-flesh, she lazily stretched and twisted in the sun without a care in the world.
It was certainly a sight to see; what was a normally lanky changeling, subconsciously packing on the pounds in all the right places, as she took in all the ambient love and lust from anyone who tried so much as to steal glances at her. It truly was amazing to see how the titularly titanic changeling managed to writhe around as she did, buried under her freshly-acquired sets of weights. Her cleavage alone had become insane, almost entirely shrouding her figure, having gone from barely-there to over a yard long. Yet even that wasn’t the most eye-catching feature of her chest - no, that honor went to the peeking green of her scarcely concealed nipples.
As with every part of her, her teats had morphed into gigantic parodies of their former size. Though the top of her bikini did what it could to hide the vibrantly colored bits of chest flesh, it was a lost cause. The seemingly tiny triangles of her top, which had once fit her breasts rather comfortably, were only just able to cup each erect, seemingly fist-sized bud of flesh, with parts of her slightly-engorged areolae peeking out from behind in every direction. To say the metamorphosis was captivating would have been a tragic understatement - there were several audience members to Yvette’s expansion act by now, though they were watching from a distance, and each of them were fueling the ever-so-vicious flames of her subconscious urges. Even with people gathering around - some unwittingly - to become amateur voyeurs, Yvette seemed ignorant to it all.
Alongside her ever-increasing curves, there was another sensation around her outfit that she was becoming increasingly aware of - the growing tightness that could be felt as all of the straps did their best to keep the beachwear together. Now having long-since run out of both length and slack, they were starting to split at the seams. Everywhere they could, they dug into her now-extremely-fleshy bits; her top was so tight that - at a glance - one might have thought that she had had four boobs instead of two.
Cheerfully humming to herself, Yvette’s impromptu and somewhat dubious exhibitionism came to a jarring end when the sound of tearing fabric caught her ear. Cocking her head, ignorant to the what was easily hundreds of pounds she had accumulated, and peeking down at herself, she gasped. It was only then that she realized that the top of her bikini, which had fully covered her chest, had been reduced to little more than two pieces of flimsy cloth over her teats.
Whilst she couldn’t see which part of her bikini had lost the battle against her oncoming outline, she was sure that it had been part of the hem of her bikini top. Attempting to get a look at her lower body, she discovered that her belly and chest thoroughly impeded her view, and gulped.
She felt her elytra spring open, which only served to further tighten her now-micro bikini top, squeezing her insane bust and threatening to destroy her upper garment. If her then-monumentally huge rack was any indication of how bad things were, her behind was likely mountainous. The startling revelation that she’d grown to such an immense size was immediately eclipsed by two things; first of all, she was still in open view of the public - secondly, the ardent flow of power hadn’t slowed in the slightest. Reaching around and pulling at her elytra, to take some of the pressure off of her cloth-and-floss outfit, she ignited her horn. Magically flinging all of her belongings onto her towel and fashioned a makeshift bindle, her unease reaching nigh-unfathomable levels.
There was no way she could stay on the beach - that is, unless she wanted everyone to get one heck of an eyeful. If she had to guess, judging from the almost-overwhelming feeling of tightness from where her top dug in, the lime green of her areolae were likely visible. What had started as a lighthearted romp to bolster her confidence had somewhat quickly devolved into a scandalous and wholly immodest display - and didn’t show any signs of slowing down. With her garments clinging to her for dear life, likely threatening to break at any moment, she dashed as fast as she could back to the relative seclusion of the changing booth.
The trip across the sand, though short, was easily one of the most arduous treks she’d ever taken. Not only was moving in a body more than triple its normal size and held back by a bikini that was under immense pressure immeasurably difficult, but she turned every head she came across. The more people who saw her, the more she fed - the more she fed, the larger she became. The cycle was as vicious as it was depraved, pushing her sanity - and her ensemble - to the brink.
The worst part was that, deep down, she loved it. She knew it was wrong; that the only reason the beachgoers were paying her any mind was because of her obscene bust, brilliantly bloated belly, and doubtlessly behemoth-like behind. And yet her id reveled in it. As obscene as it was, she wanted more. She was already almost impossibly curvaceous, but something deep within her hungered, practically begging her to take it to the next level; a near-primal instinct to absorb all the ambient immaterial love energies around her. However, the more self-aware part of her mind reined in those debaucherous thoughts. If she went any further now, she’d have the most awkward of wardrobe malfunctions, and explaining herself to the authorities for indecent exposure at the beach was not on her list of things to do today.
Crossing over the final series of dunes, spotting the small set of outbuildings, her awkward, clumsy pace quickened. The sooner she could get herself out of view, the sooner she could do her best to cut off the feedback loop, and stop her body from expanding to the point where she’d be unable to get home. Her scampering across the dunes had worked against her higher mental faculties, and only worked to bring on even more bystanders to her situation - which itself only served to cause her to balloon out further.
During her not-so-fast yomp across parts of the beach, Yvette had managed to pack on even more weight from her admiring spectators, to the point where it felt like she was hauling around five additional copies of herself, instead of what felt like the three that she had hastily left with. All of the affection she’d unwittingly consumed forced her to literally squeeze into the changing room - sideways. Upon heaving her things into the corner, she wiped the sweat beading on her brow. Never in her life had she been forced to beat such a hasty retreat, and that was including the failed siege on Canterlot! Finally away from prying eyes, she turned and gazed at her reflection.
Things had gotten so, so much worse than she’d initially thought. Her once modest outfit looked like a joke. Twin patches of fabric barely covered her large, painfully erect nipples, while the bottom of her bikini almost seemed to have disappeared entirely. She could feel a tightness everywhere that the straps on her poor outfit dug in - a sign that, if she were to grow even a millimeter more, there’d be more than just a wardrobe malfunction.
She was lucky that nobody was inside the room with her - not that there was much room left, given just how much she had thickened out - or else they’d be at-risk of being hit by bits of bikini remnants flying at terminal velocities. Whirling around as best she could in such a now-confined space, looking over her shoulder, and seeing that her prodigious posterior had all but consumed the lower portion of her two-piece, she groaned.
She looked like a harlot, albeit an excessively curvaceous and voluptuous one. Still riding that mental high from when she was outside, and with a heavy sigh, she sorcerously absorbed the last remaining bits of ambient, lingering affection that she could sense, and let herself go.
Her stomach churned, doing its best to deal with the influx of energy that it had been tasked to manage; the background absorption it could handle, but the sudden influx pushed its processing powers to the limit. The love and lust magicks in the air, now that their source had been cut off, were quick to dissipate if she didn’t get to them in time, and the few scraps that she did take in proved to be more than enough for her to achieve her desire; one final surge of growth.
With a surprisingly thunderous sound, the scant bits of fabric still holding her bikini together were torn asunder, and each piece that wasn’t clamped betwixt two body parts promptly fired itself against the changing stall’s walls, and landed with a satisfyingly resounding THUD. Her sarong fared better than the rest of the beach outfit, resigning to simply pulling itself apart at the knot and gracefully falling to the floor around her.
No sooner did her top burst open than her bosoms flopped free; in her extremely large and positively engorged state, her unquantifiably large chest had exceeded any reasonable bra size measurement at least thrice over. Her boobs collided with her gut - a gigantic, now completely split double belly, complemented with the biggest, deepest navel that she had had thus far - with a resounding PLAP, causing waves of motion to flow across her newly-acquired oceans of voluptuousness. With that much weight shifting at once, she stumbled, sending even more waves of jiggles throughout her plushed-up figure.
Assessing her stability, she stood upright and took a better stance. Now that the feeling of tightness across parts of her body was no longer clouding her mind, she was free to realize just how good she had felt during the entire ordeal; mindlessly squirming about atop her beach towel, not fully knowing all of those people who were witness to the events unfolding before them, how wonderful she had felt deep down once she had realized that she was accumulating weight across her body, to even the sensations that she had had when she was fighting with the changing-room’s doorway - it all made her feel exceedingly warm and giddy inside.
Alas, she’d have to save those feelings for when she got home, where she didn’t have to worry about peeping toms getting too close for comfort or the authorities going after her for indecent exposure.
Hovering the remains of her valiant - but ultimately defeated - set of swimwear over to herself, Yvette undid the knotted strands securing some of the remains of her bikini together and stuffed them into her bag. A small, depraved part of her mind wanted to keep the ruined ensemble as a small trophy of sorts, to remind herself that no mere bikini will ever be able to hold back her luxurious curves.
Extracting her previous outfit, an entirely new problem presented itself - there was no way in Equestria she’d be able to fit into her other set of clothes.
With few other options available, she resigned herself to have a seat. Even if she slowly expended the energy she’d unwillingly accrued, she’d probably stuck sheltering in the tiny chamber for the better part of an hour or two. Retrieving her small tome, she heard the bench creak and groan under her bulk - as though it were threatening to break if she was even a feather heavier.
She did what she could to get comfortable - adjusting her extremely meaty tush every which way until finding a position that felt like she was sitting on a pair of bean-bag cushions, before she let each of her positively mountainous mammaries off to the side so that she could rest her arms on them, and her book atop her sumptuously swollen stomach. In the end, she rested on nothing but her own plushness; her non-swollen parts sinking in surprisingly deep, she was that soft.
If Yvette had learnt anything from this entire ordeal, it was that the next time she went to the beach, assuming that there was a next time, she’d be sure to bring a whole host of variously sized swimsuits for the endeavor...
