Cadance finds out about Poison Joke... The Hard Way.

We all know the effects Poison Joke can have. From elongated hair to a voice that could rival a boat horn, the peculiar plant has a rather crude sense of humor despite not being able to speak. And this strange mystery of nature is not one to show mercy, even to a princess. So when Princess Cadance mistakes this practical joke plant for an exotic herb for a tea blend after a trip to Ponyville, she'll find that the effects can be rather shocking and possibly... Enticing~.

Warning: Contains Fat, Weight Gain, mention of personal pleasuring, hunger kinks and LOTS of belly noises!

Prologue: A Peculiar Plant For A Princess

Being a princess was never an easy thing to get used to, especially when it comes to the scheduling. Every meeting, public appearance and heck, even bathroom breaks being put on a timeline for ‘Optimal’ time usage. But for Princess Cadance, that was not an option that she liked nor allowed her staff to suggest. She, among the four princesses, wanted to set the record straight that while royalty have their commitments and obligations, they have every right to step away from the throne and take a break. Therefore, the Princess Of Love decided to take a little time off to explore the hometown of her sister-in-law for a day trip, Ponyville.

She had only been to the small town once before to see the artifacts displayed at a traveling museum featuring the escapades of the famous Starswirl the Bearded. Though since then, she had been swamped with work towered so high, she could have sat in the stacks of papers like they were a second throne. Thankfully, she decided to take control of her destiny and fit in another trip to the little town.

Once there, she took a look around town at the fine establishments it had to offer. She stopped by Twilight’s castle to obviously say hi and spend some time with her and her friends. She always liked being around the Mane Six, telling jokes, having fun, just being casual. But after a while, things started to get into the more romantic side as she, Rarity, Twilight and Fluttershy began to get into the nitty gritty…

–

“So Cadance, how's life been for you lately?” Twilight asked, taking a sip of the tea she made for the group.

“Decent, nothing too interesting along the lines of actual engaging life experiences.” Cadance said plainly.

“Not even in bed?” Twilight retorted with a waggle of an eyebrow.

“Now Twilight, it almost sounds like you think me and Shining have lost touch romantically. I can assure you, we have not slowed down at all in our romantic endeavors. Flurry Heart should be a clear example.” The pink princess said with a smile.

“I couldn't agree more! Romance is the most important thing in a mare’s life! You can't just stop it and expect it to stay that way, it will always be there to haunt you regardless.” Rarity said, fluffing her mane up.

“That's very true. Any mare can say they have no love life. But really, they just don't want to acknowledge that they have a chance at getting one. Ms. Cheerilee always says she doesn't have an interest in finding her special somepony, but it's no secret that she holds a special place in her heart for somepony else from how she acts.” Fluttershy added.

“I could say the same for you, Fluttershy. You seem to neglect your own love life as well, and constantly too. I know you're a shy pony and all, but you could do with a bit of a boost.” Rarity said.

“Oh, I don't know. I don't exactly have the body of somepony that would be worth dating anyway.” Fluttershy said in woe of herself, holding her massive belly to emphasize. Recently, the yellow pegasus had gotten into the newest craze of weight gain. For the past few months, the trend of eating yourself until you look like a blubber ball was an increasingly popular thing to do, and Fluttershy was no stranger. She loved eating all the food she could to make herself bigger, her figure reflecting how proficient she was at packing on the pounds.

“Oh don't be so hard on yourself, Fluttershy. There are plenty of ponies who love a plump mare with love handles. Take it from me, I've seen many a stallion with Mares with chubby written all over them. You gotta remember, the body isn't something you can make into perfection, perfection is your body in its best form.” Cadence encouraged. Twilight and the others agreed wholeheartedly.

“Really? Because I don't remember Shining Armor showing you any more affection after that baby weight started to show.” Twilight said, perplexed.

“Are you kidding!? He loved my body even with the added baby bulk. Nothing about my body would ever get him to love me less, skinny or fat.” Cadance said, tracing her lines with her hands.

“Speaking of which, I've heard things are changing in the world of romance lately.” Fluttershy popped in. “I heard in the new magazine, Big Beautiful Mares Monthly, that ponies with a bit of a gut are starting to attract more males than even top supermodels.”

“Is that true? I never would have expected something so… unusual to be the driving factor to a better relationship.” Twilight said, scratching her head.

“Fluttershy is right, the wider set mares of the world are starting to rise up from the shadows.” Rarity pulled up the latest edition of the aforementioned magazine. “Big Bellies = Big Success! Recent interviews with the more plump population of Equestria show that a mare with a bit of flab on her middle is the hottest craze there is. Statistics say that a staggering 41% of males in Manehattan alone love a mare whose gut is out and about.”

“Wow, I'd have never expected something like that to take the top spot for romance options. But then again, weirder things have sprung up in recent years.” Twilight recalled.

“Trust me Twilight, when it comes to a ponies’ secret interests, they will be more on display than even their fashion sense. I've seen and heard my fair share of interesting love ideas, and this one is no different. A pony can like a bigger mare if he or she likes, it's just preference.” Cadance said.

“Well, these preferences are certainly getting more strange by the minute. Listen to this…” Rarity said, prompting the others to listen in. “Highlights in the world of kinky romance. From big bellies to the noises they make, the statistics have shown it all. Apparently, the noisier a mare's belly is, the more sexy the body. Males and females alike have been interviewed from all over Equestria and the main consensus is this: A noisy belly is a sexy belly.”

“Wait a minute… You're telling me that ponies have a kink for the sounds of their partners’ stomachs?” Twilight asked with a confused look.

“That's a… very interesting thing to be romantically attracted to.” Fluttershy added.

“Well, I won't say that something like that isn't… strange, it isn't too uncommon. My day court isn't only a place to speak opinions about my rule and catching up with the latest in business dealings. It's also somewhat of a romance council, seeing what ponies find odd, strange, or downright scary about romance and making them comfortable in their thoughts and emotions.” Cadance explained.

“That's a great thing to be doing for your subjects.” Fluttershy started. “I had to get some help from Rarity to feel comfortable in my own fur once I started to gain weight. I mean, I am a big mare myself now.”

The yellow pegasus stood up for emphasis and showed off her body. She wore a comfortable combo of a sweater and flexible pants, her form as big as a professional plus size model. Her breasts were almost as big as her head, their place firmly perched upon her massive gut. The round blob pressed against her sweater, the indent of her belly button being seen by all and the sheer size rivaling even that of a bear.

“Wow, Fluttershy, you've got yourself a pretty impressive figure. You'd make some serious bank if you were a plus size model.” Rarity complimented

“I have to say, it's impressive how well it compliments you. But, I could think of somepony else who could use a bit of pudge on their body…” Twilight said, cheekily staring her sister-in-law down.

“Oh come on, I couldn't possibly be that big! Plus, my slim figure is what makes me… me! I couldn't go as far as to stuff myself silly just to impress somepony!” Cadance said.

“Oh I'm sure it could work out for you, darling! Look on the bright side, I hear Celestia and Luna have taken steps to embrace their heavy sides lately. Word on the street says Celestia recently was spotted at a bathing suit shop in Canterlot and walked out with a very large two piece.” Rarity giggled.

“If that is true, then I suppose it wouldn't be too hard for me to get into the groove along with my aunts. Maybe I could start my weight gain journey and see for myself?” Cadance wondered aloud. Looking at the clock on the wall, she saw that it was about time for her to return home.

“Well, I suppose it's getting late. I should be getting back to the Crystal Empire now. It was nice spending the day with you all.” She said sweetly, waving goodbye as she took her leave.

Exiting the castle doors, she watched as the sky began to turn orange over the horizon and decided to take one last walk around town before she left. She started with the main streets around town hall, admiring the old building style of the town as its architecture was nothing like she'd ever seen. Next, she went to the markets, seeing the last of the day's purchases being made at antique stores and shops with infinite amounts of knick knacks to buy. Finally, she made her way to the edge of the Everfree Forest, walking down a shaded, but less dangerous path through the trees and greenery as the sun shone through the canopy in a fantastic streak of orange-red.

Upon reaching the midway point around the hut of Zecora, Ponyville’s zebra shamen, she noticed a few plants at her feet that looked as beautiful as the day itself. Fluttershy had told her that the herbs in the Everfree Forest were rare and worth picking for some tea on her last visit, so she decided to take some with her to the Crystal Empire. Collecting many colorful plants in a small bag, she moved over to a patch of blue flowers that smelled vaguely like cinnamon.

“Mmmm, these smell lovely. Strange that Twilight never told me about these before.” She said to herself as she grabbed a few handfuls and stuffed them in the bag, tying it up as she made her final steps out of the forest and to the train station.

–

Later, in the Crystal Empire…

Cadance returned to her kingdom to a warm welcome, kisses from both her husband and daughter as they made sure she was as comfortable as possible. While Flurry Heart told her mother about her day, Shining Armor took the husbandly liberty of preparing a few surprises for her return. A bath at her favorite temperature with bath scents to liking, her favorite nightgown, and a little snack to tide her over. But even with all of the comforting and demands from her husband to take it easy, she remained adamant on making her own calming tea for the night.

Reaching into the pouch she used to collect the herbs, she decided to use the blue flowers she found to settle her thirst, grinding them up with a mortar and pestle into a fine dust and combining it with some other ingredients. Mixing it all together, she came out with a blue liquid that seemed to bubble a little.

Hmm… strange for a liquid to bubble even though I haven't heated it up. Even so, this is the Everfree Forest we're talking about. Twilight did say strange things happen to the plants and animals from that area, so I suppose I should expect something odd.

Heating the cup with a little magic, she drank the tea along with a few tea cakes and some nuts as a snack. After sipping the final few drops, she instantly felt that familiar warmth flow around her body as she grew drowsy by the minute. As she walked to her chambers, she suddenly felt a little bubbly inside her stomach. She guessed the tea had something to do with it initially, but her sleepy brain didn't give her a solid answer. Climbing into bed, she said goodnight to her husband and drifted off to sleep.

Little did she know, things would change for her in the morning. And many questions would be asked and answered with the new experience she was able to have.

A Beautiful Belly's Bellowing Borborygmus

Morning shone through the windows of the Crystal Castle, the warm sun waking up the Princess Of Love gently from her slumber. Opening her eyes slightly, she stretched out her arms, legs and wings and her body awakened slowly. She laid in bed for a few moments, embracing the day's sunshine fully and preparing for the upcoming responsibilities only a princess had to endure.

But before she moved, her stomach woke up and gave a small growl while waiting for its first meal.

“I hear you, you'll get your food soon. I just have to get up.” Cadance rotated onto her bottom and planted her feet into her slippers, riding the edge of the bed to gain some momentum into standing. Strangely, her body seemed to be weighing her down a bit, a little sway in her movement as he stood up. Along with it came an unusual sloshing from inside her, as if she had more tea last night than she remembered.

Okay… My body feels a little heavy and my stomach is sloshing around. I might have drank a little too much tea last night trying to get to sleep. Silly me.

Cadance chuckled to herself, moving over to her standing mirror to tidy up her mane and tail. But when she got to standing in front of the mirror… she saw something very different from what she was used to.

She gasped at the reflection she saw, almost stumbling at the sight. Her body had changed. It had gotten… bigger. Her legs were beefy and had fat in all places, her hips much wider than they had been before. Her face was chubby and her cheeks were rounded. But what she noticed the most were her breasts and belly. Removing her gown and revealing the purple lingerie she was wearing, she saw that her body was not only chubby… she was straight up fat!

Her breasts filled out her cups like ice cream on a waffle cone, pink fur overflowing in some places and her nipples visible at her tips. Her belly also was bigger, the biggest thing on her body. A gut rounder than a ripe melon pushed against her garter belt and poked out from under it, hugging the sides like a loose, but firm hug. She was fighting every urge to scream out in terror like Rarity would in this situation, but she managed to keep herself calm by using her breathing technique.

“W-what happened to me? I look… enormous.” She said to herself, analyzing her form in detail. She snapped the links in her legs and watched and the fat absorbed the impact, moving up to her hips and placing her hands on them. She saw that she was able to hold her whole hands up on them before they eventually rolled over to her Cutie Marks. That being said, her Cutie Marks stretched over her hips and even warped over her butt came into the picture.

Her tush swallowed the panties she wore entirely except for a little at the top, basically revealing everything she had and then some. Turning back around, she put her hands on her giant belly, rubbing it as she pressed in on her newly acquired pudge. Her gut felt heavy but soft, fuzzy but round, flabby but firm. Everything about her was now…

“Chubbylicious.” She said in an airy voice. Looking down, just to make sure she wasn't hallucinating, she grabbed her belly and squashed it in her hands.

All real… but what if…

Holding the sides, she wiggled it a bit and heard the sloshing from earlier becoming more noticeable. Letting go, it wiggled and moved for a few seconds before resting at its flabby position.

After doing that, her belly growled again. But it wasn't what she thought would happen. The surface of her belly visibly moved, the fat on her belly jiggling and bubbling along with it. Cadance watched as the layers of fat moved on their own, shifting her fat around before coming to rest soon after.

“Okay, let's set a few ground rules…” She started. “1: Overnight, I seem to have grown in size and weight. 2: My stomach sounds like a bubbling cauldron. 3: Said sounds are making my stomach move around like a loose jello mold. All things considered… Something went very wrong with something I ate last night.”

She racked her brain with possible culprits in this added weight from last night, recounting everything she did before she went to sleep. Then, her stomach piped up again.

“Oh hush you! I can't think of I can't hear anything!” She said harshly, her gut retorting with just as violent a comeback. Perhaps her gut was having a bad reaction to the herbs? Could she cure it? Or maybe, this was a sign of something bigger.

“Maybe… This is a sign from my inner subconscious. I was talking about how I couldn't possibly enjoy or find satisfaction in having a bigger figure yesterday. Perhaps my magic did this to me and this is my own way of testing the waters.” Her belly gurgled in response, almost as if it was encouraging her to explore. Shining Armor and Flurry Heart were off on a Daddy/Daughter trip for the next few days, so the castle would be all to herself.

“Okay then, let's see what exactly I'm dealing with here.” Cadance declared. Walking back from the mirror to get a full picture, she went about feeling her belly over.

She felt it over and noticed it had two layers. A smaller top layer that was more firm and a bottom layer that was all squish. Clearly, she had a double belly, her belly button smushed between the two and deepened to a degree that would make it look like a pit made out of pure darkness.

She touched the surface lightly and felt how malleable it was, easily moving around her finger and swirling the fat. Lowering the garter belt of her lingerie, she slapped the blob and watched it jiggle. Waves careened over her belly, starting at her belly button and pulsing out and across like a central nerve sending signals.

“Wow, it's like my belly is acting like Whinny the Pooh-ny’s belly from the childrens books. Wiggling and swirling around…” Cadence chuckled a bit. She actually started enjoying the sight. Just then, her belly growled, stuttering and shaking the fat on it. The blob jiggled and jumped around, almost cartoonishly so. This continued for a few more seconds until something else happened…

Pop!

Her belly grew larger. Cadance was surprised, her belly was just a little smaller before, but was now wider and bigger than before. It had more volume, the double layers were gone and most importantly… She felt good about it. It was hard to explain, but she actually felt rather aroused by the sight, sound and feel of her plump figure. Everything down to the last drop of fat on her body seemed to turn her on. And it made her want to take it further.

“Well, this is… interesting. I wake up after talking down about the idea of having a plump figure, I get said figure and now, I'm turned on by it. Maybe I should push this to the next level?” She said, a newfound confidence riding up her spine. With said confidence, she decided to share this new endeavor with three other big ponies she knew. Grabbing three pieces of parchment and writing on them at the same time, she sent three invitations to her castle to share what she now wanted to embrace. The hypnotic feel of her noisy body.

–

Later on, in the Crystal Castle…

Cadance sat in wait for her guests to arrive, snacks and drinks set in place around a circle of fluffy cushions to sit on. Cadance patiently watched the clock tick by, feeling her massive form over and over as she sat there in both curiosity and now a new sense of intrigue. Despite the larger than life wake-up call, she soon grew more comfortable with the prospect of her form gaining a few pounds, the slim figure of her princess body being replaced with a soft, wiggly fat that moved around on its own.

Speaking of moving, without anyone to ‘Seduce’ with sound, her belly idly moaned and groaned, the occasional lurch or bubble disturbing the surface. Soon enough, her first guest arrived in a blue flash of magic. Her Auntie Luna came dressed in a purple dress that covered her entire body, flowing with sparkles and patterns of constellations. But one thing that stuck out was her bulging belly in the middle.

Recently, Luna found the time to indulge herself in the modern sweets and other foods of today's age, taking no offense to her own larger body becoming more and more noticeable. Sitting down on one of the cushions with her legs crossed, she addressed her niece.

“So… would you like to explain the rather confusing nature of your message? Not that it wasn't interesting, is all.” Luna asked.

“Well, it's sort of hard to really wrap my head around it. When I woke up this morning, I woke up to this.” Cadance lifted the front part of her dress and revealed her large belly, an accompanying gurgle to go along with it. This surprised Luna to a decent degree, her sight locked on her niece's plump pouch.

“Interesting… it seems your stomach has grown significantly overnight.” The lunar goddess said.

“I know, but that's not the weird part. The weird part is the fact that everytime it growls or makes any noise, I seem to be turned on by it. I suppose this should be no surprise considering what my prevailing theory is.” Cadance explained.

“Hmmm… and what would that theory be?” Luna asked.

“I was talking to Twilight and some of her friends about the usual romance topics when Rarity brought up the fact that girls with big, noisy bellies seemed to be the big craze for guys and personal pleasure. Fluttershy said that she was gaining and Twilight herself said I could use ‘Some meat on my bones’ and that I might like it too. I got sheepish and denied the fact before I decided to head home. Later on, I found this pretty blue flower that smelled wonderful as I was making a slight detour through a forest path and I decided to take it home for my evening tea. After making the tea, it seemed to bubble without a heat source to warm it.”

“I ignored it and heated the liquid up to temperature before drinking it and heading to bed. Then, this morning, I woke up and found my body to be extremely plump and my belly to be more noisy than a brass band in highschool. My theory is that my magic enhanced my tea to give me this body as a sort of karma for how I reacted, a subconscious act to show me that I might be wrong.” Luna hummed to herself as she thought about her niece's words.

An odd amount of fat gained overnight and a feeling of arousal when presented with the noises of her stomach? That doesn't sound like magic…

“Cadance, you said you used a blue flower for your tea last night, correct?” Cadance nodded. “Did this flower have petals both sticking up and drooping in a star-like arrangement? Small blue pollen buds sticking out of the center and a faint glow?”

Cadance nodded again. From that silent answer, Luna knew exactly what she had ingested. “Cadance, I believe I know what has happened to you. And it doesn't involve your magic.”

“Really? What is it?” Before Luna could speak about what she had to drink that night, the second guest walked in. The Princess of the Sun herself, Celestia waltzed in with a bathing suit on. It was a bright red with swirls and circles adorning the fabric with a net at the center that showed off her cleavage, her top barely being able to hold her much more hefty breasts. Her butt was no different, the red bottoms being much more visible, but still getting swallowed whole. And her belly was much to show for.

A white blimp hanging over her thighs but still maintaining a sort of rounded oval shape while sagging. Sitting down opposite of her niece, she greeted her sister and began speaking.

“Cadance, so good to see you again. I see that you've become much more rounded since I last saw you.” Celestia chuckled. Cadance rolled her eyes.

“Very funny, Auntie, but this isn't exactly what I'd consider a social call. Well, not entirely at least. Think of this as a get together/experiment.” She spoke.

“How so?” Celestia asked. Luna told her the mean and mode of why they had been summoned and Celestia had to concur with the theory she presented as to why Cadance was experiencing these new abilities.

“I must agree with my sister. What you are experiencing goes beyond the realm of magic. It sounds much like a plant we've both had to deal with in the past. Poison Joke.” She said sternly.

“Poison Joke?” Cadance parroted in confusion.

“A plant only found to grow in the Everfree Forest on the outskirts of Ponyville. The plant you speak of using as an herb has a tendency to turn ponies into much… different creatures. The pollen of the blue flower has been the only way that's been recorded to have a lasting effect.” Luna said.

“Poison Joke is an interesting thing. As the name suggests, the flower’s effects cause adverse reactions that would only be described as something straight out of a practical joke book. Twilight and her friends experienced the effects first hoof when their zebra friend first made her appearance in the small town, the effects ranging from an enlarged tongue to a deepened voice and even unkempt fur that resembled the coats of a yak. And like my sister has said, only the pollen the flower excretes when in proximity of another creature has ever been documented. But from what you have said, you went a step further and ingested it.” Celestia added.

“So that's why I felt so odd today. And it explains the odd… changes I've been going through. Has there ever been any other reports of ponies ingesting Poison Joke and the aftermath?” Cadance asked, the blue alicorn shaking her head.

“Unfortunately no, there has not been anything reported related to how you took on the strange properties of the Poison Joke’s effects. There have only been theories of what could happen after eating the flower, but in terms of documentation, you'd be the first case.” Luna said as the third and final guest appeared from the hall, surprising the Royal Sisters. The last guest to arrive to the occasion, sporting a thong and bra in a lime green shade was actually Fluttershy.

Her body was much like Celestia's, but her belly was much bigger. Her belly was a large bubble of yellow mass, lines moving from her belly button and across her belly that faintly gave the shape of three sections of fat. Her cups were also large, the bra she wore only barely covering up her nipples and revealing everything else to see of her yellow orbs. Sitting down with her legs in front of her, the princesses greeted her.

“Fluttershy, good to see you. It's been too long since we've talked. How are you?” Celestia asked.

“Good, thank you. I know I'm usually the sheepish one in my friend group, but when a friend asks me to come over to, quote ‘Feel comfortable in our own fat’, I won't turn it down.” Fluttershy said, twirling her mane on one finger.

“Well, it's good to see you here with us today.” Luna said, turning back to Cadance. “So, my dear niece, how shall this get together work?”

“Well, I was initially going to test this on my own. But, I decided that it wouldn't be useful to just do this alone. Perhaps, in some odd way, this isn't just exclusive to the Poison Joke and we all can find pleasure with all of our larger than life bellies. So, I gathered some of the best snacks, drinks and a few potions of Borborygmus to ignite the flames within us.” Cadance said, a much more confident tone of voice.

“Borborygmus? That's a funny word. What does it mean?” The yellow pegasus asked.

“It's the scientific term for the sound your stomach makes when you're hungry. But society chooses to use more simple words to describe the audible discharge of your midsection’s motion. And with these potions, they will induce that noise artificially to test the waters.” Luna explained.

“This seems strange, even got you, my niece. Why do you want us to partake in this?” Celestia asked.

“For all the romantic things I suggest to other ponies in my court when they ask me for advice, I suppose now would be a time to take that same advice and apply it to this. I will admit, I am slightly.. turned on by the sounds of my body. And I would like you all to take this on with me as a sort of.. experiment to see if you all have the same reaction.”

“Well, I've never been a fan of potions, but I'll give it a go!” Fluttershy declared.

“Then it's settled. Ladies… let's make some noise. First, let's get some food in us to add a base.” The group then grabbed from the snack pile and took to their eating montage. Bags of chips, gummy bears, bowls of chili and soda disappeared into the bellies of the ponies. Gulp after gulp, a good portion of the snacks were sampled and swallowed.

“Okay, now you three use the potions to get your stomachs started. I have the natural advantage already, but I may choose to use it when needed.” Cadance said, the other three guests nodding as they popped the corks off the bottles and chugged them all down until the liquid within them was gone. Placing the bottles on the table they all leaned back and let out a sigh. Luna revealed her perfect ball of a belly as she lifted up her dress while Celestia and Fluttershy held the sides of theirs as they let the potions settle.

“Okay, here we go. Let's see what we've got.” Silence came over the room for a few seconds, the idle air swirling around them as they all waited for the first sound of the symphony to begin. Soon enough, Cadance heard her belly start with a warbled gurgle that echoed through the room, strange bubbling adding to it as the pink ball bellowed.

“Ooh, you were right. Your stomach is really loud…” Fluttershy said, looking on as the pink blubber of Cadance's middle visibly moved

“I told you. She's been very talkative all day today. I'm starting to think it has a mind of its own.” Cadance said.

“I see. I suppose this comes from the Poison Joke in your system radiating out into the world. Curious how it doesn't affect us at all.” Celestia said. Then, the sound of growling bellowed from her insides instead of Cadance's. Her belly growled like a mad beast, the snarling reaching critical mass and shaking her gut before going silent.

“I'm impressed, dear sister. Never have I ever heard your bowels emit such a sound so close to a Manticore.” Luna teased.

“Oh don't start, Lulu. You have just as much of a brass band in your belly as I do, so don't act like you don't have your moments.” At that moment, Fluttershy's gut gained its voice and began a roar of rumbles that shocked the rest of them. Her yellow gut shook and shuddered under the pressure of the potion, the rumbling making her belly look more and more deformed as it moved and jiggled.

BRRRRRRBRBRBBRBBRRRRRRRRUMMMMMMMMMMBURURUURURURUUUUUUUUUUURB!

“Goodness! I haven't heard that much noise come out of my body since I started this gaining thing. That potion must be strong for it to have this type of effect.” Fluttershy exclaimed, holding her belly still.

“I have to admit, a sound of that magnitude coming from you? That is a true surprise. I always knew the shy ones had the loudest moments when the time came to it.” Luna added, soon remembering her own commitment to the challenge as her belly began to sing.

Ripples of fat rolled over her belly, a deep moan bellowing through her innards. Bubbles and gurgles soon followed as the potion worked its magic on her with a loud signature.

“Well, it seems all of the potions have begun to take effect. Now it's time to join together and embrace our new forms.” Cadance moved the table over and allowed them to have some more room. Gurgles rose up from below and rattled her belly even more, as if responding to the added noise of her guests’ own outbursts.

“Ooh, that's a big one. What's wrong, my sweet? Feeling a little bubbly?” Cadence's belly responded by roaring with an up and down wiggle, as if nodding to her.

“It seems like your insides have a mind of their own. Perhaps we all have a little personality within our bowels in some way.” Celestia said. Her belly lurched at the sound of her voice and gurgled its own response.

“It seems we all have a different inner voice within our loud bowels. Personally, I think this might turn into a new pleasure for many a mare from this day on.” Luna suggested, rubbing her midsection.

“Actually Luna, it already has.” Fluttershy passed a newspaper article to the blue alicorn. “It's already becoming a thing to listen to your belly by yourself or with friends for pleasure. They're calling these get-togethers ‘Belly Bashes’.”

“Interesting. Perhaps this little Poison Joke accident can be turned into something entertaining? Maybe I could add more to this experience and have other ponies join me here over the next few days to do so.” Cadance scratched her chin in thought. This little incident has led her to find a brand new interest, or in this case, a developing kink that she was increasingly becoming fond of.

“Now I'm getting new ideas! And one of them just came to me.” Cadance said. “Let's go two on two, belly to belly.”

“An interesting concept. Fluttershy, would you join with me?” Luna asked. The yellow pegasus nodded and scooted over to her, pressing her belly to hers. The heat from their bodies melded nicely, the feeling of the direct contact satisfying them both. Cadance and Celestia also went along with the idea, their smaller guts coming together as well.

With the four ponies now teaming up with one another, they waited for their next noise bombs to be dropped into their bellies. Luna and Fluttershy would be the first to take to the stage as Luna's gut roared with Fluttershy's and created an even bigger noise.

Brrrrrrerrrrrrrrrourrrrrorrrup…

The other two princesses weren't too far behind as their joined tummy tango echoed through the room.

Grrrrrrourgerrrrrrrrrrourrooooo…

Both pairs let their guys ring out as teams, almost like they were battling to see who had the most in them when it came to noise. Just before anything could go further, Cadance's belly began to bubble on its own. She pulled away from her eldest aunt and watched the surface roll and move.

Celestia, Fluttershy and Luna also noticed their guts began to howl, like a pack of Timberwolves was on the hunt. Each one of them felt the roar of the internal turmoil twist their insides and just about stopped all other thoughts in their minds. The sound of their bellies were so powerful that it was almost like they were hypnotized into listening. The three guests stopped their guts from going overboard, but Cadance let hers continue.

“Y'know, I've come to accept what this Poison Joke has done to me. And I have come to the conclusion that I will continue down this road and test it with others. This will be a strange thing to get used to, but I have full faith that I will prevail.” Cadance declared, getting all approving nods as she made her list to continue this little caper of hers into the next group she'd come to meet. Her and her noisy insides.

Author's Note

There we go! I finally managed to get this done. Took me a while to work out some of the kinks (No pun intended), but I got it done and that's all that matters. Looks like Cadance has found a new pleasure to pursue. Will she find more ponies to bond with over their bellies? Find out next time on the next chapter of: Hypno-Tummy!

A Myriad Of Melodies From Motherly Midsections

After a little conversation with her aunts and a few tips on how to manage her gaining from Fluttershy, Cadance was now a fully fledged gainer in Equestria. Even though her initial gain was an artificial addon from a blue prank flower. Regardless, she was ready to take on the next level of her adventure.

Cadance awoke from her slumber and yawned quietly, stepping into her slippers once again to look at herself in the mirror. This time, she took no shame in dropping her robe to see her new body, a few new additions bringing her some joy.

It had been a few days since her first unofficial ‘Belly Bash’, but she was not deterred from going the extra mile to enjoy her new pleasure. She may have also encouraged Shining Armor to stay gone a few more weeks so she could have more time to herself as a precaution, just in case. In tandem with her planning, she also began personally adding onto her frame with more sweets, her favorite chocolate treats filling her up nicely.

Soon enough, she was more squishy than ever and was looking much less nervous. Her hips were much more rounded and plump, a smooth surface holding her still massive cutie mark but with a much less warped design. Her cheeks were much the same from before, staying cute and round as she smiled to herself. Her breasts took a small dosage of the added pounds, only adding a few inches to her bust.

But her belly… That was a different story. It grew tremendously, the double layers returning with a vengeance only Chrysalis could achieve. A much larger portion of her gut hung under her garter belt, showing all the way around until where her hips started.

“Wow… I've really pushed myself to the limit.” She said with shock. “But… I feel good at that limit. Maybe I could even go beyond that… Only time will tell I suppose.”

Putting a hand to her middle, she felt its enriching softness. The feeling of her fluffy fat almost made her want to just spend the day playing with it. But today was not that day, as for today… she'd be hosting an official Belly Bash! The name was still one that made her giggle a little, but the concept was interesting. From what Fluttershy told her, it was a group of ponies getting together to embrace their bigness and enjoying the feeling of their fat. Adding on the newly found interest of hearing said pudge bubble up a storm, it was a funny thing to explain.

“Okay, now that I know exactly what I'm dealing with, let's see what I have…” Cadance pulled a scroll from her dresser and read its contents. Scribbled over the parchment, she could see lists of popular snacks, drinks, a reminder to restock on those potions she used before and three guests that she had yet to invite.

“Okay, it seems I have everything laid out. Now, what to do first…” She didn't need much time to think as her stomach gave her a clear answer with a torrent of rumbling that made her belly shake.

“Oh right… Breakfast.” Cadance blushed and rubbed the back of her neck. “After all this time of eating to my heart's and stomach's content, I still can't remember about the first meal of the day.”

Making her way to the dining area, she sat down at the table and had the castle staff make her double what she usually ate. That is, if they could take their eyes off her. It was nothing she hadn't done before, walking out in nothing but lingerie in the morning before she even got dressed. Some days, she was just too hungry to clothe herself and just had to get some food in her before the day started. Most of the time, the staff would just serve her as usual, the sight of her bare body being a sight that they'd been conditioned to get used to.

But ever since she began putting on the pounds, the reactions to her body have drastically changed. Of course, she expected the initial shock of her major change in appearance, but the reactions of the castle staff almost seemed… shy. Perhaps the sight of her larger form made them bashful?

Soon enough, the food came and she tucked in. Fluttershy had advised her to increase her food intake in order to aid her appetite in the future. She told Cadance that even though she looked big on the outside, the Poison Joke most likely didn't change much on the inside, including the size of her stomach. So as a precaution to give her an edge in her future gaining, she increased her food intake to expand her insides and stretch how much she could handle.

Cadance has to admit that she was very surprised that Fluttershy of all ponies, the one who used to be afraid of her own shadow, was giving her tips on how to find self pleasure in her big size. In hindsight, the yellow pegasus gave off a sense of underlying secrets beneath all of those shy moments. Even so, she took all the help she could get.

She finished breakfast and let out a satisfied sigh. She didn't feel full, but she knew she was making progress. Ringing a bell, she notified the servers that she was done and went about her day. Moving into the kitchen, she levitated a bunch of different snacks over to her, grouping them up in a large bubble to carry as she moved along to the alchemist room.

This seems to be going well. Everything I've got will certainly be enjoyable by the guests, especially that special drink I had ordered. Now for the potions! These three are much more experienced at this than I am, so I'll grab the extra strength variant.

Entering the potion room, she greeted the lead alchemist.

“Frogfoot, good to see you again! How have things been going?” Cadance asked.

“Oh, I've been great! Things have been much easier ever since you enlisted these other apprentices to my ward. It's been smooth sailing from then on ever since!” Frogfoot said, waving the pink princess inside. The brown unicorn stallion had been the head alchemist for the Crystal Empire for years, mixing up every potion from Lava Resistance to Weightlessness. And now, he was tasked with making the newly ordered Potions Of Borborygmus.

Originally, he had felt rather embarrassed to ask his colleagues for instructions on how to create a potion to intentionally set off someone's stomach. But once he had realized it was for the princesses, he got right to work on the job, practically plastering it on his forehead to remember the formula.

“So, how goes the making of the potions I requested?” Cadance asked.

“Great, thank you for asking. I will admit, my initial reaction to your request was very… vibrant, for lack of a better term. I told myself… ‘Who in their right mind would want to set their stomach into a frenzy!?’. Then, when I heard the recent news and caught up with the trend, I got right to it. The formula was actually very simple, believe it or not.”

Frogfoot and Cadance turned a corner and came across a large cauldron where two mares were mixing a familiar green liquid.

“Alpine! Frosty! How goes the potions!?” The lead alchemist asked.

“Brilliant, sir!” Alpine said, her yellow eyes bright with excitement. “We've just about finished the mixing process. We've added all the ingredients except for one. Concentrated Citron Juice, Bubble Fruit, The Gas Of A Sulfur Vent, Swamp Tree Acid, and finally…”

Frosty walked over and dropped in the final ingredient. “One Hot Shot Pepper from the Dragonlands. The perfect combination of heat, bubbles and agitating agents to get your stomach going.”

The cauldron shone with a green flame before beginning to bubble and swirl on its own, indicating that the potion was ready to be distributed. Cadance watched with interest as Frosty took a syringe and sucked up a bit of the mixture and put one drop in her mouth. Within seconds, a growl ripped through the air before a burp came from the white pegasus’ mouth.

“Yep, this batch is definitely extra strength! Now, for one last thing…” Frosty took out a spell book and recited an incantation, a flash of blue pulsing in the cauldron before the original green shade returned.

“Can I ask what that last part was?” Frosty nodded and turned the book to her.

“It's a sealing spell to keep the gas from overwhelming the effects of the potions. With the Bubble Fruit, Captured Sulfur Gas and Citron Juice, the reaction is a solid way to get a monster burp out of someone. But no pony is trying to hear a belch when the sounds of their stomach is what they're after, so the spell seals away the gas and redirects the excess energy to create more sound, leaving the belly bubbling reaction of the potion you're looking for.”

The pink alicorn nodded and took a personal note of the process, just in case she wanted to make the same thing on the go. While she got the specifics of how each ingredient added to the effect, Alpine and Frogfoot scooped up the potions into the appropriate bottles for her to leave with. Taking them in her arms, she bid the group farewell and left to set up the spot she would use for the bash. On the way out, she borrowed some parchment and ink to write the invitations and sent them off to their respective recipients.

Cadance hummed to herself as she thought of her first conversation about the possibility of having any success with a larger body. Now that she was finally embracing what she had been ‘Gifted’ with, she had to admit that she was wrong about what she thought before. She actually did enjoy having more weight behind her movements, not to mention the personal pleasure she got from it.

Entering the room she would use for the bash she set up the place. Instead of a table, she just laid the snacks on the ground, placing one potion each next to every cushion. Sitting in her spot, she excitedly waited for her guests, occasionally patting her belly just for the feeling.

–

A Few Hours Later…

After waiting a good while from the beginning of her bash, the first guest walked in. Wearing a black two piece, Cadence welcomed in her own mother-in-law, Twilight Velvet. Having gained a tight relationship with the mother of her sister-in-law, she had become very close friends. After she got her acceptance letter, Cadance was very excited to see what she'd be met with, and she wasn't disappointed. Velvet was a very evenly spread mare, her fat going everywhere in decent quantities to give her enough pudge to have a belly, but also balancing it out with a sizable rear and a decent cup size.

“Cadance, good to see you again! It's been too long, honey!” Velvet said sweetly, taking a seat.

“I know, it's been a very interesting few days to be honest. First thing, you find out you accidentally drank Poison Joke and gave yourself a body to put a walrus to shame. Next, you're having your lead alchemist mix up a potion to make your stomach go nuts because you've started to get turned on by it.” Cadance chuckled sheepishly.

“First Belly Bash, I'm assuming?” Cadance nodded in confirmation. “Well, let me tell you, this isn't the first time this was a big thing. Back in my hay day, before I got married, I was dug in deep with the whole big belly thing. Every soda I drank brought me new waves of pleasure that I didn't know I wanted or enjoyed. Unfortunately, it couldn't last forever as I forced myself to slim down tremendously for my big day to please Night Light.”

“How long did it take you to shake off the chub?” Cadance asked.

“10 weeks. It was a major change, but it was worth it to eventually bring the Princess of Friendship and a Royal Guard Captain into the world. I only recently got back into the trend after I decided I wanted to take myself back to my greatest moments. At least, in my opinion, that is.” Velvet said. “I missed having this big body, feeling how soft and squishy I felt was the best! Now I get to experience that again.”

“Well, I'm glad you feel that way. I'm just getting started and I'm inviting verified veterans in the trade to show me what the pros did.” Cadance said with a chuckle.

“Oh don't feel so bad, everypony has to start somewhere. Speaking of which, who did you bring in?” As she said that, the next guest walked in. Her large belly walking in before her face even appeared, Spoiled Rich, Wife to Filthy Rich and mother to Diamond Tiara strolled in with confidence. He bedazzled two piece accentuated her breasts, her large bust showing off a lot of fur. Her butt was just as large, rounded and plump like Cadance's, but it stuck out much more than hers. Her belly was the biggest part of her, a perfect ball of fat rounding out her figure as she sat down with a sloshy accent.

“Velvet… Your Highness…” She addressed the pair.

“Spoiled Rich…” They responded. The room fell silent for a few seconds, a measure of tension tying things together like a haphazardly wrapped gift. Spoiled Rich was one who had a reputation, and not a good one. A pompous attitude, snobby way of speaking and overall entitlement made her much to despise, that same attitude rubbing off on her offspring. Soon enough, the wealthy pony broke that bondage.

“Oh come on, let's not act like I'm the same pony I was all those months ago. I've changed!” Spoiled argued.

“Oh we know…” Velvet started, pausing to give the peach colored pony one last bit of stress. “We just wanted to mess with you.”

Spoiled sighed as the two other ponies laughed at her, knowing her reaction would be cataloged in their memories for a long while.

“Ha ha, very funny.” She moaned, crossing her arms.

“Oh come now, Spoiled, you've grown from the pony you were all that time ago. Thanks to what your daughter learned from the Cutie Mark Crusaders, you have gained a new sense of purpose and morality. You deserve a good life, like anypony else in this world.” Cadance reassured her. Spoiled smiled and thanked the princess, knowing that her change in attitude didn't go unnoticed.

“So, you were a part of the original craze as well?” Cadance asked, the wealthy pony nodding in affirmation.

“My milk farming heritage led me down a path of mostly liquid gaining. Fluid pumps, jugs of our own product, sugary drinks… all going down my gullet over the years as I gained my weight. Over time, I eventually discovered that potion you mentioned. I took one sip and I felt a roar below my breasts shake my middle. After that, I was hooked. I eventually slimmed down as a choice, my rich husband showing me the good life and encouraging me to lose the pounds so I could enjoy it as much as possible. I did retain some of that weight in the form of a double chin and slight love handles, but it was hidden enough that fur-tight dresses still looked sexy on me.” She explained.

“Huh. So you also lost weight before your marriage?” Velvet said aloud. “Hmm… it seems a trend is forming.”

“Perhaps…” Spoiled said, looking over to Cadance's body and observing her form. “So… how did your pudge come to be?”

“Believe it or not, it was actually accidental. I mistook a batch of Poison Joke for natural herbs and mixed them into my evening tea. The next morning, I woke up with a body that wiggled around like jello and a belly that rumbled like a volcano. I decided to host an unofficial bash with my two aunts and a friend of Twilight's and I finally understood what this fat was meant for.” Cadance explained.

“Interesting. I've never actually experienced the effects of that accursed plant, thankfully… But I have always wondered how different the effects would be depending on where you took the hit.” Spoiled said.

“Me too. When Twilight told me about her little mishap with Poison Joke turning her horn limp, I immediately started forming theories as to how else the flower could produce its strange effects. Creams, oils, dusts… every single external application possibility ran through my head. But never did I think of what would happen when you drank it or ate it.” Velvet thought.

“Celestia told me that I'd be the first case of ingesting the plant, since no other cases had been recorded up until then. So, I guess I decided to make it something exciting.” Just then, the door opened wide and the final pony walked into the room. Golden Brooch. She was a pony Cadance had met during her pregnancy with Flurry Heart when she attended that yoga class for expecting mothers, her also having a daughter later on.

Her body screamed Mom Bod, her thighs and hips being absolutely huge in her semi transparent leggings. Her breasts were just as big, filling out her outfit along with her large gut. That being said, her cream colored belly was a big one. The large bulb was held in her hands, her one piece being the only thing covering it except for a small heart-shaped window exposing her belly button.

As she sat down, her belly slipped out of her hands and jiggled… a lot. Her belly wiggled and wobbled for a long time before coming to a rest in her lap. The other ponies looked between the mare and her belly, amazed at just how much movement she held in her gut.

“Wow Golden, even I don't have that much movement in my gut and I've been at this for years.” Velvet said.

“Well, when you've given birth to one kid and felt the effects of the post-pregnancy fat, you get a little jiggly after a while.” Golden Brooch giggled. “Also, Cadance, it's good to see you again! How's little Flurry doing nowadays?”

“Great, thank you. Now, let's get your story. How did you acquire your big body?” Cadance asked, the other guests turning to engage.

“Well, I've always been a bit plump anyways. But as for how I got bigger? Well, after I gave birth to my daughter, I began feeling a bit bored with my life. Just a baker on Buckley Lane in Ponyville that occasionally gets glances from young colts going through puberty? Not very enticing. Just after my divorce, I loved getting the attention of the young ones. Showing off my hips with fur-tight dresses and other generous clothing. But after a while of being single and raising a child, it gets old. So I decided to go find something to bide my time.”

“Soon enough, I came across this cheeky little article about gaining weight and embracing a ‘Bigger Lifestyle’ to appease your loneliness. So, I dove right in. Being a baker meant not much money spent on outside food and more time spent stuffing myself with my own confections. After a while, I had a belly to be proud of and a figure to match. A few years later, I came across a friend of mine taking a swig of a strange drink. At first, I thought it was soda. But after hearing that belly rumble, it was no mistake I was staring at the potion that would take my experience to new heights!”

The other mares nodded along with the rest of the story and were interested in finding out how she came to enjoy her life as well. Cadance especially enjoyed hearing the story as it validated her feelings in a way, knowing that she was with some of the veterans of this little craze she jumped into.

“Okay, so we all have a story behind our gaining and we've all settled in. But before we get things started, I have to ask… what exactly brought on the making of this special potion before?” Cadance asked, grabbing the one she gave to Velvet. The grey unicorn started the conversation.

“Well, originally, it was made for medicine. From minor cases of curing hiccups with a strong burp to major life-threatening ailments like dislodging a Colic blockage, the bubbling from this potion was considered a medical miracle.” Velvet started.

“But over time, like most things intended for an entirely different purpose, the public snagged the formula for the medicine and began experimenting with it to find a practical use for it.” Spoiled added.

“Many things were tested to find its more public usage. A solution for over-tanning at the beach to clear away sunburns, a way to make a homemade Jacuzzi from the bubbles, even an exfoliating lotion to bubble away blackheads! But after results kept coming back showing that the mixture only worked on stomach acid, the directions changed. After years of testing, ponies eventually went into the… personal pleasure department. Soon enough, the critically acclaimed potion came to be as the go-to way to pleasure yourself with your own stomach sounds.” Golden finished.

“Wow. Who knew that such a simple thing turned into such a complex web of pleasure. I like it!” Cadance said. “Now, without further ado… let's get this Belly Bash started! Now, drink up ladies!”

The four mares popped the corks on their potions and downed the liquid in the bottles. Once the liquid disappeared, they put the bottles down and sat back.

“Just as a heads up, these ones are extra strength, so they'll pack a punch. Now, let's eat up before the show begins.” Grabbing the snacks, they gobbled up everything they could. Cadance made sure to get extra just in case they wanted more, but for the time being, they filled up on what they could. Golden's belly was the one that expanded the most, the rounded blob becoming even more rotund as they ate. Eventually halting the food fest, they settled in and waited for the fun stuff.

Velvet was the first to undergo the effects as muffled moans ran through her belly. Bellowing whale calls roared from her midsection as the grey plumpness of her fur slightly moved. At first, the strength of the potions was put into question as the reaction from the grey unicorn was minimal. But once it started to kick in, the moans became groans that sounded vaguely like a Cragodile.

“Ooh… now I can see why these are extra strength. Feels like a stampede in there.” Velvet said. Spoiled Rich caught the next wave as her massive gut began to bubble wildly. The peach colored mass rolled and rocked as the cauldron of food she had for a belly moved around like a blob.

Golden Brooch was next, her middle growling wildly in an almost predatory tone. The ripples rolled over her belly, her one-piece hiding that fact like a bush holding an elephant. Even the small window on the front moved around a bit in response to her rowdy insides.

“Woo, talk about a wake up call! Haven't felt this much activity since my hay day. That extra strength was a definite plus.” Golden said. Cadance was glad she had brought out some old memories from her guests. But she wasn't done with her road to glory. Reaching over to the snack pile, she pulled away a green bottle with a very stylish label. Bubbles popped and fizzed within, the explosion effect surrounding the logo being a definite sign of its volatile nature.

“Now what do you have there?” Velvet asked.

“An old favorite soda brand from my highschool days. Fizz Bomb Cola! Back then, mostly the boys would grab this thing to have some burping contests in the middle of lunch. Got themselves more detention slips than I could shake my tail at. Now, this drink of old times shall be used for the betterment of our cause.” Cadance explained. Popping the cap off the bottle, more bubbles roared up in the liquid, nearly blocking out the sight from the outside of the bottle and making it look like the liquid was more bubbles than soda. She then proceeded to grab 4 big jugs and pour each to the brim with the Fizz Bomb Cola, passing them out to each of the girls present and then raising her jug.

“Bottoms up, ladies!” They all proceeded to chug their entire jugs of Fizz Bomb Cola in a matter of seconds, expanding their bellies to the near point of touching. They all eagerly awaited the effects of the Fizz Bomb Cola, then Cadance’s belly started rippling fast like a storming ocean, moaning like a pod of whales all sounding off at once, it even shook the floor a bit from how loud it was. This was then followed by Velvet's belly, squirming around harder and faster than a gazelle being caught by a cheetah, and it growled loudly like one too.

Spoiled Rich was not much further behind them. The blob of fat she possessed wiggled like jello on Heartswarming Eve, groaning like a pained animal. The sheer mass of the effect even shook her sides, making her feel as if she was no more than a rider on this wild rollercoaster. And lastly, Golden Brooch felt her insides turn wild. Every fibre of her being shook with vigor and wrath she hadn't felt in years. Her gut rumbled like an avalanche, rattling her frame and pulsating out from her belly button.

About 20 minutes of this passed, with each of them feeling immense pleasure from this, until at last it stopped. However, this had left all of them becoming more bigger because of it, with all of their bellies now officially touching each other.

“Well, I must say that was some incredibly strong stuff.” Said Spoiled Rich. The other two agreed to this sentiment. Cadance felt much the same, but she felt like something was missing.

“Well, that was agreeably, something I enjoyed very much. But I still feel like something is off. You three were into this when the trend first kicked off. What else did mares do to add to the experience? Surely, just some potion wasn't all you did, right?” The princess asked the veterans. The other three looked at each other while still holding their bellies. They nodded concurringly to their nonverbal thoughts and decided to give Cadance the rundown of how things went back in the day.

“Well, before this nifty little potion came to be in this day and age, us oldies had to find our own way to set our stomachs off.” Velvet explained.

“Since potion making was still a solely academic and professional career choice and basically no creativity was going into their creation, we had to do it the old fashioned way. Finding the most volatile foods known to pony kind to really ramp up rumble production. Having no experience with potions and to be honest, not wanting to go through all of that high class mumbo jumbo, we set off to the best ingredient stores we had at the time… Snack Shacks!” Golden said proudly.

“Being teenagers at the time and prices being much smaller than today, we had allowances big enough to get us a myriad of snacks, drinks and other things to mix up our own homemade ‘Potions’ from scratch. Bags of Chili Cheese Chips, fizzy soda, breakfast burritos… it was all we needed to not only fatten ourselves up, but get our guts riled up. It was almost like a competition to see who's belly could make the most noise.” Spoiled Rich chuckled. “But of course, no lady in her prime highschool years wanted to admit that we were just as gross as the boys. Especially one like me.”

“So we kept it on the down low, waiting until we got back home to start the fun.” Velvet said, whispering for dramatic effect. “It was such a fun time, heading into your bedroom or basement and just going to town on your own potions and watching as you expanded and your belly rippled, it was even more fun if you had a friend…or even a hook up to get in on it.”

“Hook up? So guys were getting in on this too?” Cadance asked, but she got head shakes in return.

“Not a chance, Cady! Any guy at that time would have run to the masses and made it front page news if we made our little kink public. No doubt, they'd use it as ammo against us to prove we're just as nasty as they are and prove that we had no right to complain about their habits. Even a slip up in conversation was something we couldn't risk! Plus, no guy would understand the pure pleasure of the trend, it was too coded to those with more… feminine assets. So, we mostly kept it to ourselves. And those hook-ups? Yeah, they were all lesbians. It was basically a ladies only kink that we developed over time. Only difference being it's a lot easier to do what we meticulously planned for with that fancy shmancy potion of… Bubble Regus or whatever.” Golden said.

“Borborygmus.” Cadance corrected.

“Right,” Golden replied as she continued. “As time went on and we got older, we had a lot less time for this kink as we all had to slim down for one thing or another. Family, College, Marriage and even workplaces. It’s been a really long time since we’ve been to a Belly Bash, but it’s been great to go to another all this time!” The other two nodded in agreement

“Too true, it's been ages since I could finally let myself go and feel the softness of my body press up against something. Celestia and Luna deciding to not so secretly join the fun motivated me to get back into it.” Velvet asked.

“Speaking of motivation… Cadance, you said this new body was accidental due to you sipping on some Poison Joke, right?” The pink princess nodded.

“Well, a little thing about that. Don't make it feel like an accident. If you constantly keep it in the back of your head that you got this from an accident, you dull down the pleasure of it all. Act like it was intentional, give yourself some confidence and strut your stuff.” The gray unicorn said.

“Also, just a tip from a baker and overall food expert, Go. For. The. Spice.” Golden said. “Every bit of heat you can pack into that pink pouch of yours, you'll be able to up your tolerance for the bubbly stuff, including that potion.”

“And round out that belly of yours as well. You may not know this, but there are actually spells that allow you to shape your body.” Velvet said, teleporting a spellbook in front of Cadance. Inside, she saw a diagram of a mare with lines around her body, indicating some sort of change.

“Use this every few bashes to even out your midsection. It's not just cosmetic, it can actually expand your insides as well. Do what you want! Give yourself a double belly, make it round like a ball. Flabby, bouncy, jiggly, make your choice.” Velvet got closer to her ear and whispered. “Also, don't tell anypony about this, but you can manipulate the sound yours makes with that spell. It's how I won a bet back in college.” Cadence promised to keep it a secret, the ladies all chattered for a little while more before they all went home. Velvet, Spoiled and Golden all slowly waddled out the door with how huge they'd gotten.

Cadence, after all this, was now writing down everything they said and also taking up the advice to now see this as her getting big on purpose. Now she could fully enjoy the pleasure as she then used the book to round her belly out, as well as adding extra fat everywhere else, especially her butt to make it more comfortable sitting during these belly bashes. Satisfied with the results of the day, she went to bed now thinking of how to make this trend become more than a trend, and more commonly accepted among society.

Author's Note

Well, it sure seems Cadence is now fully into this, as well as getting some knowledge and info from those who were there during the original trend, but what will she do to start making fat mares and noisy bellys a more common place in society? Who will she get involved with to help with her plans? Find out in the next chapter of: Hypno-Tummy!

A Royal Rundown On The Reputation Of Rumbles

Cadance awoke next morning, feeling out her entire body as she slowly got out of bed. Having remembered what Velvet had said, she was finding it very enjoyable fondling around her body in the morning, feeling more comfortable than ever in her own skin. Walking over to her standing mirror, she observed her massive body and saw her progress in full.

Overnight, she'd let all of the snacks she'd eaten the day before digest and form into more squishy pudge, adding to her body's growing mass. She also got into the habit of midnight snacking, going for loads of spicy foods and other gas producing morsels to follow Golden's advice of building up her tolerance. Cadance was honestly surprised she was able to get back to sleep with the torrent of noise her belly was making trying to break down the snacks, but Spoiled Rich told her that once you get used to it, it was basically like self made white noise. As she looked at herself in the mirror, Cadance felt as though she was comparable with these beautiful models in this little world of plus sized mares.

“Maybe I could do some runway modeling for fat fashion.” she chuckled to herself, before a thought struck her memory, remembering how she was planning to make plus sized mares a more common thing, she thought of Rarity.

“Rarity did say big mares were on the rise nowadays. Perhaps I could help her start on a plus size clothing line for her boutique?” She wondered aloud. Her stomach bubbled, triggering another memory.

Velvet had told her that listening to your belly's noises was an old fetish of hers and many other mares of her time. Maybe she could reignite the flames and get it back in style to do so. Her own gut was a noisy one as is and she was advised to do it as well.

Speaking of which, a grizzly growl roared from her belly, getting a giggle out of her. “Oh, aren't you a noisy one? You like being all consuming of my thoughts, don't you?”

She drummed her fingers on the surface of her belly and listened to it retort in roars and rumbles, all rippling the surface as she did so.

“Velvet told me that a bubbly belly is something that she and her gal pals like to embrace back in the day… But, it does still seem out of my repertoire at the moment. What to do…” She thought about it while rubbing her belly, the softness of it acting like a stress ball to use for thinking. Just then, an idea popped into her head. Looking back into the mirror, she saw her aunts by her side, hands on her shoulder as if showing her the way.

“That's it! I'll go back to Canterlot and ask my aunties for help! They shouldn't be busy today, so a little surprise visit wouldn't hurt. Plus, they could give me the rundown on what all of this bubble guts glory was about back then! Brilliant!” So, she went and found a giant trench coat in her closet to cover herself as to travel incognito, then with a fedora and some shades, she headed off to Canterlot. In her haste, she didn't grab breakfast, but that would prove to be of no issue as the upcoming conversation she'd have with her aunts would require her to be a little less than full.

–

A Few Hours Later, In Canterlot…

Cadance strode her way through the streets of the capital city of Equestria, minding herself as to not reveal her identity or her recently plumped up physique. With the trend of stuffing oneself to the limit rising to levels not thought possible, the conversation of the increase of one’s weight spiked exponentially. And being that the residents of this fine city were more on the… uptight end of the attitude spectrum, the reception of the idea was less than welcomed within the inner circles of the elites. She overheard a conversation between 2 snobby mares having some tea.

“I must say dear, whatever is this world coming to?” said the blue one.

“I know, it’s shameful all these ponies are just incentivising being nothing but snobbish hogs, it’s very distasteful!” said the green one. Cadance rolled her eyes as she continued along, but hoped one day this town's attitude will change to those with bigger bodies. She'd gotten used to the snobby sort of pony after a while, her time in Canterlot as a juvenile basically desensitizing her to the whole idea of elitists complaining about the interests of ‘Common Folk’.

“Maybe one day, a big mare will be in your little elite circle.” She quietly whispered to herself. Walking out of the city limits and into the vicinity of the castle, she showed her face to be identified by the guards and asked them where her aunts would be at the time. Surprisingly, they said that they were to not be disturbed as they were engaging in ‘Important Royal Business’. But with a wink from the one on her left, she got the message and nodded as she entered the castle's walls. Walking through the halls, she eventually dropped the act and removed her disguise, handing the coat, hat and glasses to a servant who happily took them away as she continued on with her day.

As an extra layer of safety, she put on a glamour spell to make it look like she was wearing her usual royal attire to the outside eye. But underneath, she was still in her lingerie. Walking up to her auntie Celestia's door, she lit her horn and instead of knocking, sent a psychic message inside to get permission to enter. A few seconds later, the door unlocked and Cadance invited herself inside. There she found Celestia and Luna in their lingerie with lots of food, drinks, potions, and giggling with each other.

“Why hello Cadence, I must say, you have gotten larger since we last met.” pointed out Celestia.

“Yes I have, thank you for noticing. So this is the ‘Important Royal Business’ you had to attend to?” Cadance chuckled.

“We must admit, this little trend that has started back up in recent times has been very interesting. I say, it's very entertaining to excuse ourselves and indulge in our favorite foods.” The white alicorn said.

“I could say the same for myself. I decided to throw my first Belly Bash yesterday with a few other mothers to sort of get an understanding of how the trend worked back in the day.” Cadance said, dropping the glamour spell. “But one thing still eludes me…”

“And what would that be, dear niece?” Luna asked, wiping some cheese puff dust off her face.

“The affinity with making your belly noisy. I get the overall concepts and how to enjoy it, but how it came to be and how to master it is still not in my skill set. So, I came here to see you two on how to do that.” Cadance sat down next to them, forming a triangle and getting comfortable.

“So, you understand the trend of getting big and enjoying the lifestyle, but the image of letting your stomach ring out on purpose still brings up question marks?” Celestia asked.

“As much as I hate to admit it, yes. Even after doing it twice before with you and my other guests, I still can't see myself doing it often due to the sheer fact that I'm clueless on how to effectively do it. So, I wanted to come to the two ponies I know have been in the game for a while and exclusively focus on that aspect.” The two sisters looked at each other and nodded as they simultaneously agreed to spread the good word.

“Well, if you must know, you've come to the right place.” Luna said as she began to explain. “Many moons ago, when the trend of stuffing yourself to the brink of bursting was well in effect, ponies found it boring how they just had to be big and that was it. They all wondered if there was a way to find more enjoyment in their achievements. Luckily, they did.”

“The trend on making your belly noisy was something that shined out from the dullness of just eating large quantities of food. It added somewhat of an additional layer of pleasure to it all. Mares all over would privately sneak away to their most secluded hiding spots to indulge in the fetish, often choosing spicy snacks and bubbly drinks before that potion you've been using was created and eventually given to the public.” Celestia added.

“I can attest to the increase in popularity being more prominent in the dream realm. Ponies with bellies as big as a large water balloon took over the majority of what I saw, the roars and rumbles of their midsections creating a lot of noise as the night went on.” Luna said. “In order to truly master what you are seeking, you must go further than just a little noise. You must be willing to push your internals to the limit, creating such noises that no pony would ever think of.”

“Think of your stomach as not just something to pack full, but something to ignite and stir up. Everything you eat will have an effect, but you must go for the very aggravating substances to truly gain a sense of pleasure. If you do choose to go down this path, be prepared for your belly to make constant noise. Because between the three of us… mine and my sister's bellies are so loud, we make rooms shake with them as if we have a second Royal Canterlot Voice within our guts.” Cadance nodded and took all of the knowledge down to remember for later. She had to really push herself this time, no holding back.

“Okay, I understand what I have to do. Let's do it.” She said confidently. The sister's smiled and accepted their niece's request, showing her the mountain of unusual snacks they had.

“These were personally made by us to cause as much disruptive force within our bowels as
possible. Join us in our partaking in our little symphony, and you will not regret it. Trust me, these bellies will show you that much. Observe.” Luna obtained a red ball from a bowl on the floor. Placing it on her tongue and giving her niece a wink, she swallowed and let the ball drop into her belly. Once the ball made an audible splash in her belly, Luna began jiggling her belly. Sloshing of great magnitude came from the blue ball of fat as she shook it side to side. She stopped suddenly in the middle of it to give her belly a slap and as she did that, a growling akin to a Grizzly bear filled the room.

The sound was tame for a starter, fairly low growls emitting from Luna as she rubbed her midsection.

“Wow, I had no idea you took this so seriously. You make your own food to aggravate your insides?” Cadance asked.

“Indeed. As I said, our bellies can be so loud that they can shake rooms. And the only way we can do that is by manufacturing our own little ‘Tummy Treats’ to get them going. And we are going to make the same deal to you. We'll make you into a master of making Belly-quakes yet, my dear niece.” Celestia said.

“Belly-quakes? Is that what you call them?” Cadance giggled.

“Yes, like making an earthquake with your belly.” Luna replied as she then got another of the red balls and handed them to Cadence, which she then did what Luna did by putting it on her tongue, and swallowing it and letting it drop into her body.

“Good, now when sloshing your belly around, try not to force it too hard, try to naturally move and slosh it around like you would with yourself in a bathtub.” Advised Celestia, to which Cadance started the sloshing her belly around with her hands, which was a bit of a struggle given how big her belly was and how overall huge she was, but she persevered trying to keep a smooth natural movement in her belly whilst also applying force, afterwards she let her belly go and smacked it with both her hands. To which, her belly then moaned like 2 whales, giving a little rumble to the room.

“Hmmm… perhaps your belly is too weak to handle one of these just yet. You may need a more gradual start than this.” Luna said. “I say we build up on this, letting your insides naturally acclimate to higher volumes of noise before going again. We could make a little game out of it.”

“A capital idea, sister. We'll all eat one at a time, listening to our bellies in turns and see who's got the gumption in their gut as we eat more volatile items.” Celestia said. Using her magic, she placed a total of six bowls in-between them with different colored balls within them. The colors were blue, pink, red, green, yellow and white.

“Each of these orbs will cause a different reaction within us upon swallowing. We'll choose one bowl at a time and take one orb each from said bowl. One at a time, we'll eat them and listen to the noises they make of us. This will not only serve as a fun little game, but it will also give Cadance the tolerance boost she needs to reach our level. So, shall we begin?” Celestia asked. The two other princesses nodded and went about their business. Up first was the bowl of blue balls, each taking one.

“These should only elicit some small disturbance to begin, a good starting point. You first, sis.” Celestia said, her demeanor becoming more casual. Luna obliged her sister's request and swallowed the dark blue ball that matches her coat. As expected, the blue ball gave little reaction as small moans broke out from within her belly, not much to speak of.

“Hmm, a valiant effort. Your turn, Tia.” Celestia swallowed hers. Since her belly was smaller, the noise had much less space to bounce around the echo chamber of a belly she had and came out slightly louder. But no true progress was made.

“Excellent. Cadance, the turn comes to you.” The white alicorn said.

“Okay, here goes.” Cadance tilted her head back and gulped, the small orb disappearing down her neck and into her gut. Moans much the same to Celestia came out, but no true waves were made.

“A fair start, if you ask me. Now, onto the next batch.” By show of hands, the princesses chose the green ones.

“These should cause a stir within us. I know for a fact due to these being where I started out. Now, down the hatch.” Luna said, tossing one back. Placing her hands on her belly, she moved it around a bit. After a few seconds, her belly started to bounce up and down as it made growling noises that, if one were to listen close enough, could give just the vaguest impression of the sound of chanting.

“Am I going batty or does Luna's belly sound like it's mimicking old tribal chants from the indigenous ages?” Cadance chuckled with a mix of shock and amusement.

“I believe so, my dear niece. I must make you aware that while some of these snacks were purposely made with fine tuning, these orbs have completely random effects. We quite literally went into the alchemy room blindfolded with a few spells in hoof, played a spinning roulette to see which would be added and went nuts.” Celestia chuckled. “One of the less successful batches caused my belly to sound like a quacking duck.”

Cadance giggled at the notion of her aunt’s belly quacking. She could not deny that her aunt’s magic was the most powerful she'd ever seen or heard of. But to use it in such a humorous way? Cadance expected it more from Discord despite the comparatively minimal interactions she had with him. She and her oldest aunt soon joined in on the tummy chant and giggled a little as it died down. Then, they began to make their choices again.

“Now, which one shall we pursue next?” Luna asked.

“I say we go for the pink ones. They seem to be filled with a decent bit of mystery, so why not?” Cadance suggested, her aunts nodding in agreement as they all took one. Luna took the plunge first, swallowing the pink orb and doing the usual motions to elicit a reaction.

Within seconds, her belly started to ripple like a pond. A distinct bubbling noise came from the blue ball of fat, almost like what the sound of bubbles in a cup of milk would sound like.

“That sounds rather tame compared to the others thus far.” Cadance commented.

“Oh it may seem that way, but remember, each one of these can have a different reaction to each of us. Luna may sound like that, but what about me?” Celestia said as she swallowed hers.

After going through the steps to coax a rumble, her belly made similar ripples with a slightly deeper version of the noise Luna’s made. Her's made a noise more reminiscent of boiling water, a deeper and more violent sound than her sister's attempt.

“I'd have never imagined you two were so into this, and with such dedication.” Cadance said. “What happened to make you two so attracted to this?”

“Well, it is a bit complicated.” Luna started. “About a few weeks after I was rescued by the Mane Six, I was greeted by the most shocking sight. My once slim and sleek sister, who was revered for her looks and grace, now had a bust rivaling the size of two cider kegs and a belly so jiggly, it was almost hard not to stare. A little explanation as to why she was like this and the significance of the trend, I soon found myself gaining in much a similar fashion to my sister.”

“After Luna gained the form you now see before you, we became aware of this little… extra that came along with this secret fetish. The belly growling. Unsurprisingly, the sheer amount of food we were stuffing into our muzzles was causing our bellies to become less like silent slabs of skin and more like bubbling bulbs of blubber. The sound of our digestive noises was somewhat enticing to us, almost in a hypnotic way. Soon enough, we were both cooking up these special orbs to purposely make a ruckus and got so far deep into this little rabbit hole, we started to make our bedrooms shake as the morning hunger made our bellies rumble.” Celestia added.

“So, you two just became bored with how plain the fetish was like the rest of the world?” Cadance said, swallowing her orb.

“Exactly. Unlike you, who started off on this journey by accident and came to enjoy it, we came to revel in it and enjoy it to its fullest potential. And soon enough, you will do the same once you are able to make Belly-quakes.” Luna said before confidently smacking her belly.

“I like the way you think! But I have to ask.. are you two the only ones capable of such a feat?” Cadance asked as she shook her belly.

“Actually, no. We've been hosting secret classes on the matter. So far, Fluttershy has been our top… ‘Student’ as of late.” Celestia said.

“No surprise there with the amount of noise she could generate with her gut. But is there anypony else?”

“Just two. Pinkie Pie, which should be no surprise, and a certain fashion designer who has gotten into the trend and is now causing a shake as well.” Luna whispered with a wink. Cadance gasped at the description she was given.

“So, Rarity is plumping herself up now? It feels like just yesterday that she was advocating for more slim and sleek figures to go on the rise.” Cadance said.

“Oh, she still does. But she just chose to go a different route. She masks her need to get bigger as a modeling opportunity for a future plus size clothing line, but we both have seen how she revels in the noises and shaking she can produce.” Luna giggled. Before Cadance could laugh herself, she felt her gut bubble below. Unlike her elder aunts, her belly didn't mimic the sound of a liquid. Her's instead mimicked the sound of bubbling mud, a soupy sludge sound filling the air as her belly slowly rolled and malformed in response.

“Ooh, that sounds rather sickly. If I didn't see you down that pink orb, I'd have assumed you had indigestion.” Celestia said, almost showing concern over the reaction.

“Oh don't be such a worry wuss, Auntie. I've heard worse noises come out of Flurry Heart. Seriously, that baby practically has a cauldron inside her with the sheer terror she can produce. Never gave her Applesauce after that, nearly drove poor Applejack to tears.” Cadance giggled. Soon, they had all gotten their taste of the pink orbs and unanimously went for the white ones.

“Okay, these white orbs should give you a taste of what half power feels like, Cadence. These are a big jump in reactivity compared to the others.” Luna said, picking hers out of the bowl. She downed it, shook her belly, and waited for the reaction. Almost instantly, her belly was overrun with a mix of sounds, a groaning mixed with an almost animalistic growling filling her belly. The growling was a very low and ululating noise, making her belly shake immensely like something was trying to force its way out. It was so violent, she had to wrap her hands around her belly to get it to calm down some.

“My my dear sister. When you told me it was about time I ‘Let out my inner beast’, is that what you meant?” Celestia said teasingly, an out stuck tongue being her response before she swallowed her orb.

The white alicorn felt it churn within her for a moment before a snarling came out from her middle. A lion-like roar ripped through her belly like a bolt of electricity, shaking her insides like a vibrating platform normally used to burn off the fat that she and her fellow royals had built up.

Cadance swallowed hers and after doing the steps, she said, “Let’s see how mine reacts.” Within seconds, her belly moved around on its own, making the sound of a rather ferocious beast. The sheer volume and motion of her middle surprised her, the shaking being that of a stampede level intensity.

“Such a Titanic level of motion is almost insane at this point. Even with just the Poison Joke alone, it was a drastic change. But this… this is something else.” Cadance said, eyeing the yellow orbs with intent. “You know what? Let's cut to the chase and go for the gold! Let us consume… the yellow orbs.” She then proceeded to down a yellow orb and repeat the process. After a few seconds, her belly started to sound similar to an agitated cat yowling.

“Stepping into the deep end, are we? Well, let's get down to business then.” Celestia said, gulping hers down and receiving the same reaction. The two princesses felt the strange sensation rattle their frames violently, the sound making their bellies pulsate with vigor. Luna however, was not impressed.

“Such child's play. Please, watch as a true professional shows you how this is supposed to go.” Luna said before downing her own yellow orb. Not even letting her shake her gut, a loud groan filled the air, pushing her belly out before a wild burbling made her belly jostle in every direction. She gave a cocky smirk.

“You see that? That is what a true master can do when you stop toying around with things.” She said smugly.

“Oh, so you want to be that way? No surprise. Not like it's uncommon to hear your ego bang the drums so loudly.” Cadance said, a snort coming from Luna in annoyance. “Well, since we've run through everything else we had in stock, I think it's time we come full circle and come back to the one we started with. The red orbs.”

“Are you certain, Cadence? This orb is the very orb that causes the quakes we told you of. Are you sure you wish to take on the challenge that will forever open the floodgates of how much noise your belly will make?” Celestia warned. Cadance nodded and magically put three orbs in the air, one going to each of them.

“I have already come this far to embrace how big I am. Not much more to do besides getting used to how loud I'll be in the future. So, let's see how much of a quake we can make.” Candance then gulped down her red orb and shook her belly. Her aunts followed in her footsteps and gulped down theirs as well, doing much the same actions.

“By the way, Cadence, did you happen to see anything… different about the orbs we just ingested?” Luna said, a suspicious expression on her face.

“No… At least, I don't think so.” Cadance looked down and realized what she had done. Next to the orbs that she had been given by her younger aunt, were a bowl of red orbs identical to them. The only difference? These red orbs were glowing. “Should I be concerned?”

“Oh no no, these orbs do exactly what you wanted from them. They will still cause a quake… Two times stronger and with a delayed reaction.” The pink princess’ eyes widened and shrank to pinpricks.

“T-two times stronger?” She stammered.

“That is correct, Cadence. The orbs that you just chose are not the normal red orbs that you were given at the beginning of this little meeting. The orbs you chose are in fact what we like to call… Red Rumblers.” Celestia said with a little deviousness in her voice. “These ones are the pinnacle of what it means to cause a quake. Luna is the only one who has ever used these, her large belly being the perfectly round echo chamber to allow for maximum effectiveness. You, my dear niece, have stepped into the deep end and dove into the darkness. No turning back now.”

Cadance looked over to Luna, who was wearing an expression filled with pride and intimidation. Cadance fought back the urge to gulp down the lump in her throat, both because of her inner confidence telling her to face the facts and the passive fear of her saliva somehow making the reaction even more potent.

Staring her aunt down, she nodded silently to her, acknowledging that she had stepped into her territory and now had to take on what was coming in full. Meanwhile, Celestia had already swallowed her own Red Rumbler and held her belly in preparation.

“May the baddest belly win, ladies.” Cadance said. The silence in the room became palpable, almost as if it was gaining substance for them to physically grab a hold of. Seconds ticked by like minutes, the three alicorns trading looks between each other like cowboys in a standoff. The calm before the storm.

After a few seconds, Cadance felt the imminent approach of a rumble. She put her hands to the surface of her stomach and felt a strange bubbling inside. “What am I feeling right now?” She asked, both concerned and slightly intrigued.

“The fluid being added to your belly.” Luna said simply, getting Cadance's head to snap over to her. “You see, this orb doesn't just react with your stomach acid… it adds to it. When it landed down in that pink pouch of yours, it began generating a special flavored fluid that tastes like your favorite drink and fills your belly to its capacity and then some. It'll not only expand your insides to be able to handle even more food and drinks, but it will also make your insides so reactive, it makes it a constant noise making machine after the fact. There's a reason why my nickname in the trend is ‘Full Moon’.”

Luna then downed her own Red Rumbler. Despite her previous statement of it being a delayed reaction, hers gave an instant change. Her belly could be heard bubbling slightly, the fluid filling her up as well as Celestia, who had just gotten her reaction to kick in.

“I thought those had delayed reactions!” Cadance commented.

“Only the first time.” Luna said. “Over time, the delay shortens. It's just a little thing that happens to those who try them after using them multiple times after the first.”

“That's why I didn't get the instant release either. It's my first time, too.” Celestia said. “And just so you know, this isn't a secret we intend to keep.”

“You mean, you plan on handing these out!?” Cadance said, a lurch from her belly staggering her for a moment.

“Indeed. We started with you to show you what this power represents. We'll give you the recipe once this is over. But for now, get ready.” Luna said. Finally, the bubbling stopped. The fluid felt rich and filling inside of them, a gurgle coming out of them once they were sufficiently filled.

“So, when does it happen?” Cadance asked.

“Just a moment…” Just then, the chaos started and Luna was the first to take the hit. Her belly began to ripple with a deep gurgle, the volume growing louder as the reaction began to take hold. She rubbed it lovingly.

Cadance was about to question why Luna seemed to be treating her fluid filled belly like she was pregnant, but it had a message to bring. The room began to shake, the once innocent sounding gurgles divulging into the most bassy rumbles Cadance had ever heard.

Never in her life had she heard someone's stomach sound that loud, shake a room so violently and move so much all at once. Luna's belly rippled and rolled as her rumbles rocked the room, the snack pile next to them collapsing into a straight up mess under the shaking. Shortly thereafter, Celestia’s belly joined in.

Her gut sprang into action almost immediately, a mix of groaning and moaning filling the air as her belly jiggled. The movement was so potent that even her ‘Cider Keg’ breasts started to ripple themselves. Cadance giggled slightly at the sight. Her own aunt, who was once a slim ruler with a body even she wished she had as a teen, now had so much movement that even her chest rippled in the small manner as her belly.

Even so, she was not too far behind in this little quake-fest. Soon, her belly started to get crazy. But unlike Celestia, she was more on the bigger side in the tummy department. Her belly began to ring out in growls and roars that she had never felt before, her entire body feeling the shake like her middle was in more control than she was. From every angle, each of their tummies sang their siren songs like they were in a theatre. Their combined power shook the room like a maraca, the vibrations mixing things up as the fluid within them gained more and more reactivity.

“I’m going to say it right now,” Cadance said. “I am at a loss for words. I've never felt so out of control and in control at the same time. I feel so alive and… so enticed~”

“That is one of the perks of being an alicorn. We have the most magical potential out of any creature in life, and while we mostly use it to impress guests and defend our way of life, sometimes you have to let loose a bit.” Celestia said as their little rumbles disappeared into themselves and stopped the shaking.

“This is a true statement, Cadance. We always felt so bored with our lives, constantly having to uphold a regal mask to follow what society wants from us. Now, we get to try new things that we enjoy.” Luna added.

“You said it. I don't think I've ever felt this free from obligations and responsibilities before. It feels amazing to just let go and have a good time every once in awhile.” Cadance said enthusiastically. “So, this will have expanded my appetite by a good margin?”

“A very good margin.” Celestia added. “You will be able to pack so much more into your belly after having taken on this rare challenge. Along with that, you will be subjected to some alterations.”

“It's a natural reaction to the orb’s effects. We both experienced a dramatic increase in just how loud ours were, so you should be much the same.” Luna then leaned in and got close to her niece. “And between the three of us, you may find that your gut has a little more… ‘Personality’.”

“What? My belly? Personality? You must be joking!” The pink alicorn scoffed. But as she said that, she was proven wrong. At that moment, her belly bubbled in a strange way. The sound made her wonder if her aunt was telling some truth about that change in her.

“See? It's all in the middle. My sister and I have developed a similar symptom over the years ourselves. Watch…” Luna said before gesturing to her belly. She rubbed it softly in circles, gently caressing the blue ball before it began to moan in a relaxed manner. It was like a cat purring while being scratched. Suddenly, she stopped, placing her hands on top and waiting idly. As if reacting to her lack of care, her stomach growled angrily and signalled that it didn't like being left hanging. Luna simply giggled in response.

“This… this can't be real.” Cadance said.

“Oh, but it is and can be.” Celestia chuckled. She rubbed her own gut and got a selection of purring out of it. Not necessarily a literal purring, but a groaning that sounded somewhat close. Cadance was mouth agape at the sheer level of ridiculousness she's been exposed to in such a short time, the fact of her aunts' guts having personalities being something her brain couldn't compute. But that wouldn't stop her own belly from taking over. As the two sisters let their insides fall silent, Cadance took center stage as a gurgly gargling sound emitted from her belly. Hers sounded vaguely childlike.

“Well, I suppose I can be proven wrong. But, one thing. Why teach other ponies like Pinkie, Fluttershy, and Rarity to do the same? You two could have had the biggest bragging rights out of any mare who'd have the same physique!” Cadance wondered aloud.

“That is true, we could have had the bragging rights of being able to create a shake with just our bellies. But, we chose to share the wealth for two reasons. One, we hold ourselves not above our subjects, but alongside them. We feel no better nor any worse than the average pony. It is why our rule over the land has been so legendary for so many years.” Luna said with dignity.

“The second reason is a bit less glamorous or respectable though…” Celestia put in. “We gave them the tips and tricks for it because… We lost a bet.”

“A bet? To do what?” Cadance asked.

“Gain as much weight within three weeks as fast as possible. It was my sister and I with 300 bits VS our three proteges with 600 combined. We ended up losing after our massive lunch that would have put us in the lead had to be cut short due to a catastrophe in Time Square. Thus, we were ultimately forced to take on the role of teachers to give them the key to our newfound trick. After that, we thought it would be only fair to make more of these orbs and share it with the public. Like we said before, Fluttershy is our top student when it comes to learning how to do this. She got so good that she had a belly rumbling contest with Luna and won!” Celestia exclaimed, an annoyed huff coming from across the way.

“Wow, that's amazing! And you actually entertained the idea of having a contest to see who's belly was louder?” Cadance said with an amused expression.

“And I would have won if this one had decided to kick up enough of a ruckus!” Luna complained, looking down at her belly with disappointment on her face. In response, her belly rumbled deeply, as if telling her to get off its back. “Oh hush up, you…”

Cadance giggled at the little disagreement between her aunt and her gut. “So you ended up teaching them the same trick you taught me? What were the results?”

“Well, you already know who was the best at it. Fluttershy was honestly a wild card for us, a blank area that we had no idea was secretly a monster in pony's fur. She may come off as shy and not speak up much, but when she got her first taste of our little treats… Her guts went mad. Almost immediately, her belly was rumbling just as loudly as mine does. Surprised at the sheer power she held in her middle, we questioned her on her methods. Soon, we found a history of fast food, soda, beans, cheeses, roasted nuts and other things being her go-to for adding to her pudge. And she didn't even have to speak to say so.” Luna said.

“Pinkie Pie was another out of the box student of our craft. While nowhere near as potent as Fluttershy's reactivity, her gut still provided us with some interesting results. As it turns out, her belly has a mind of its own! Literally growling and roaring to every statement we brought up to it, even starting conversations with our bellies as if manifesting this abdominal sentience within us as well. No doubt she would be another great addition to the cause as well.” Celestia described. Cadance wasn't all that surprised at that assessment of the pink party pony. She already knew that with her abilities, she was bound to have some weird effects on anypony around her.

“Now, Rarity was a difficult case. Of course, being who she was at the time, she didn't want to admit she wanted in on our little proposal for fear of letting her more gluttonous side consume her and completely replace her elegance. But, after a little convincing…”

“And many tubs of Vanilla Oat Swirl ice cream being devoured…” Celestia interjected.

“She eventually fell to her inner desires and let herself be who she wanted to be. Her insides were about the same as yours, Cadance. Minimal reaction at first with a large build up needing to take place before greatness could be achieved. But, she managed to pull through in the end and now used her new abilities alongside Fluttershy on their spa dates.” Luna explained.

“So those three all have their reactions to your so-called ‘Tummy Treats’ and now use them to their own pleasure? Well, that gives me a major confidence boost. But about Pinkie Pie… Are you sure that her belly was starting ‘Conversations’ with yours and you're not yanking my horn?” Cadance asked with some suspicion.

“I assure you, we tell no lies when it comes to the abilities of Ponyville's premier party planner. It was just another session of using the orbs to build up her tolerance to the reaction, nothing particular about the day's events. Then, once she was considered a model representative of our little lessons, we experienced her little quirk. Her belly growled like any other big mare, deep and with much movement in her middle. But along with that, it seemed to have a certain… dialect to it. Soon enough, her belly began to lead her around and pressed itself into my sister. Her belly gurgled against Celestia's and a response came in turn. That's when they started rumbling together like they were in harmony, like they were literally taking the term ‘My tummy is talking’ and running with it.” Luna said.

“It's true. And she did it with Luna as well as me and then got all three of us going. It was so strange yet oddly funny. So, if you decide to include her in your little journey, be prepared for some strange happenings.” Celestia warned.

“Duly noted. But if Pinkie can do it naturally, perhaps I can make it happen another way myself?” Cadance wondered. She took another one of the white orbs from before and swallowed it, moving closer to her eldest aunt. Waiting for the reaction, she patted her belly patiently before the growling returned. It was a light disturbance compared to the first time she had one, but it still proved to be successful as Celestia's belly growled in response.

“It worked! And… I think they want to be together.” Cadance moved closer and pressed her belly against her aunt's, sitting side by side with her arm around her and watched the dynamic change. Their bellies rippled together like a combined ocean of pink and white, each alternating in crests and troughs.

“My my, Cadance. Who knew you had such a talkative tummy.” Celestia said. “Then again, you did always have a loud one. Even in your younger years.”

Cadance blushed at the reminder of her appetite. Luna, on the other hand, tilted her head.

“I believe I'm left out on this reminiscing of memories. I assume this is something that happened before I returned from my thousand year imprisonment?” The blue alicorn asked.

“You would be correct, auntie.” Cadance said, her and Celestia's bellies still talking to each other. “When I was a teenager, way before I even met Shining Armor, it was no secret that between the two princesses in the castle at the time, my appetite was the biggest while going through puberty. To say that I was making a ruckus back then would be an understatement. Every day, at least once, I'd have my stomach ring out in front of the staff as my body began to change. And every time, I'd turn as red as a cherry.”

“Well, that is to be expected. As an alicorn, your mana capacity and magical energy consumption is greatly increased. As such, your caloric intake has to compensate for that much energy consumption to keep you functioning. Though, if you say that even your appetite was larger than my sister's, I'd have to say I'm impressed.” Luna complimented. But as she watched her two fellow alicorns meld together in abdominal harmony, she started to feel a little jealous. With hers being the biggest, she was always used to her being the top dog. But now, she was getting overshadowed by the little tummy talk going on across from her.

“Hmpf, you two having fun over there?” She huffed, crossing her arms.

“Oh, don't tell me you're already jealous of our connection, sister. You shouldn't have anything to be jealous about! Besides, yours already talks up a storm as is with how big it's gotten.” Celestia said, poking at the blue mound Luna had for a belly. It rippled like a pond when something was dropped in it.

“Auntie Tia’s right, you have just as much of a personality in that gut of yours as we do in ours. Besides, it talks more to you than it would anypony else.” Cadance added. Luna looked down at the blue ball between her legs and rubbed it with a hand. A deep rumbling rose from the depths of her gut, waves of jiggling fat rolling over it like an ocean.

“Perhaps you're right. I do like how it seems to respond to me like a friend, it makes me feel warm inside.” Luna said.

“So, Cadance, what do you expect to do after you leave? Celestia asked.

“Well, obviously, I'm going to focus on making myself even bigger now that I'm in this full time. But as for anything else… I don't know. Maybe I might head back to Ponyville for another visit and see if Fluttershy would mind another pony in on her and Rarity's spa dates. No doubt that they will be just as big now that they've been around you two, but only time will tell.” Cadance said as she stuck by her aunts for the rest of the day. She was sure that with this little session and some new treats under her already tightening garter belt, she would be all set for whatever happened next. She wondered who else would be in on this trend, maybe Twilight or even some of her old Canterlot acquaintances might be in the know.

For the time being, she just enjoyed the feeling and sound of the increasing amounts of pleasure she was feeling now that she was fully embracing the feeling of being big.

Author's Note

Well, I guess Cadance has found her groove now! But what will she do now that she has reached these new heights? Who will she take on as partners in her next adventure? How much more excitement will she make of this little pleasure of hers? Find out next time on the next episode of: Hypno-Tummy!

A Merry Mix Of Muddy Midsection Magic And Mare Manicures

After achieving the skill of causing a quake with her belly, Cadance was now far from her first time into this new phase of her life, finding more to do in this little trend. Continuing to fill herself up with food and engage in eating more volatile treats, she was much more heavy and loud than she was before. The feeling of getting bigger and making her gut louder was something she'd never expected to do, but every time she heard her belly ring out in protest, it was like she had no other choice but to submit. Especially since her belly had become so loud that her room shook every time it made a sound. The reaction that the orbs her aunts gave her, which she now had the recipe for, were so potent that her belly seemed to gain a mind of its own.

From the day she got back to the Crystal Empire, she spent her time making a ruckus of her own, using her new recipes that were graciously gifted to her by her aunts to gain some pleasure on her own time. No doubt, she had gone over the crest of the hill and was now going down into the depths of what this little trend was. After her little trip, she took the time to order some new lingerie and two pieces, especially since she had basically made her old ones disappear under the blubber she had packed onto her body.

But much like her initial time getting into this trend, she found herself without anything to do. Admittedly, she was a very social pony. She may have been a princess, but she thrived around her familiars and chatting like she was just ‘One of the girls’. It had truly been a long time since she had a casual experience with her friends, only being able to spare so much time per month just to send a scroll, only to have something come up before plans could be finalized.

Thankfully, she wouldn't have to deal with that feeling much longer as she would find herself getting a certain message.

In her room, she examined the new shipment of specially made plus size two pieces she ordered, each coming in an exotic color she loved including the purple that her new lingerie set was made in. She always loved keeping her lingerie close, the fit making her feel sexy and desirable. And now that she had all this fat, she had much more to love.

The new set was a fine fit for her figure. The straps to her bra not only ran over her shoulders, but hugged her breasts over the top, not too tight but not a loose fit either. The covers were a triangle shape in a dark purple, a lighter shade being used to make up the velvet veil that ran around the edges and sparkled with golden specks. More of the light veil fabric ran across the top of her belly, a waving pattern making up the partial cover before the fabric gave way to the rest of her exposed belly. Around the lower half sat her garter belt, three large sections of veil fabric making up the front while the rest wrapped around her belly, not so tight that it made a dent but just tight enough that it pressed in while still being comfortable.

Her bottoms were a major improvement, the darker purple wrapped around her waist with much better coverage and actually covered her butt with decent effort rather than a small strip that looked like a thong. Two straps went down the front of her belly and continued to her legs, connecting to the leg straps that wrapped around her thighs tightly to maintain the form of the set.

All in all, she was a beautiful mare with a big body and better coverings that accented her bigger figure nicely and she liked it. And she would get the chance to show it off as a scroll popped in right in front of her.

A letter? Hopefully it's not Shining Armor asking what that extension to his and Flurry's Daddy/Daughter trip was.

While she was excited to possibly hear from her beloved husband, she had to tie her tongue in regards to her love of the trend. Being big was one part she could agree to speak of, Shining having no objections to his wife being big and him having more to love. But the second part was what she had to keep secret. Finding an attraction to her belly growling was definitely not something she wanted to discuss with her husband, both because of wanting to preserve the secret that many of her plus sized predecessors kept for years before and wanting to keep her own interest in the matter out of the eyes of her very curious daughter.

Luckily, her prayers were answered as the letter was not from her husband, but Ponyville’s resident fashionista.

Dear Princess Cadance…

I hope I have found you in good spirits and very well fed as I come to you with an invitation. You see… Recently, with mine and Fluttershy's combined undertaking of this strange but admittedly fun trend, it has come to our attention that our usual spa dates have become nearly impossible with our added fat exceeding the Spa's… “Weight Limit”, to put it bluntly. So, as an alternative, we have decided to go to our own private spot to take our time to relax and enjoy our bigger bodies. Fluttershy's private mud pit! With her permission, I formally invited you to join us in our muddy fun as we chat as girls would, embrace our new size and just have fun! Below, you will find instructions on how to find the pit and when to arrive. Bring your best two piece/lingerie set.

Hope to see you soon.

Best wishes,
Rarity.

Cadance smiled at the mention of a chance to relax with some friends in a little mud. She was no stranger to a mud bath herself, but the mud she'd experienced for the most part was personally manufactured by the spa to substitute the natural substance as the location of the Crystal Empire did not provide the necessary conditions for mud to form, so the thought of sitting in an All Natural mud pit was very exciting. So, she did as she was told and saddled up with her usual public disguise, her lingerie underneath and a boatload of snacks to fatten her up for the trip there. Finally, she would get the chance to chat it up with some of her more casual friends and feel the richness of a less manufactured experience.

Later on, in the streets of Ponyville…

After disembarking from The Friendship Express as to not draw attention to herself and throwing out an entire Nightmare Night's worth of snack wrappers in the trash, she made her way towards the small town on her way to the cottage of the yellow pegasus. Looking around, she saw all of the mares that seemed to be adding to their figures as well. Understandably, most were hesitant and were discussing the matter with their colleagues around town with their interests or disinterest in the trend, but a decent part of the town’s population was already on the road to plumpness.

Mrs. Cake was an obvious choice as she was already a chubby mare beforehand, her body showing much more pudge under her apron than usual. Alongside her was Pinkie Pie who, to her surprise, was even bigger than she'd expected. She couldn't describe what she saw as the pink pony strode out into town, but she could only see what was essentially a bulb of pink fat that made up her belly with the rest of her body looking like it was just a second thought when it came to where most of her sweets went.

Moving along into the market, she saw Lyra, one of Twilight's old friends from Canterlot, sitting on a quickly collapsing bench with her not-so-secret love, Bon Bon. The two never liked to admit that they were a thing, but it was clear that they had something more between them besides being ‘Bestest Friends’. She looked much like Pinkie but on a smaller scale, not having as much bulk as she wasn't on that much of a rampage yet. Bon Bon seemed to love it all, snuggling close to her love as she felt her body expand with every gulp.

Moving onto the outskirts and reaching her destination, she spied Vinyl Scratch, or DJ Pon3, as she was known on stage, listening to some music on her usual headset. But along with the set she had over her ears, she had a second pair over her large white belly that were making it wiggle slightly. Perhaps the DJ was experimenting with a new possible style of music, or as she liked to call it, ‘Wubs’ for her next show? Either way, she was well on her way to bring bigger than her with her roommate, Octavia Melody, looking rather plump herself.

Seeing all of these ponies taking on this little trend made Cadance happy, the essence of self love and acceptance radiating along the waves of magical energy nicely. Soon, she reached the door of the cottage she was meant to find and made her turn to the side path that she had been directed to in the letter. The side path she took was quiet and calm, the sound of leaves rustling and branches crunching under her feet being the only thing she heard as she walked down the path.

That is, until her belly decided it wasn't happy with waiting so long to be released into the wild and moaned in displeasure.

“Oh calm down, we're almost there. Can't you just be a little more patient?” She asked her gut, getting a begrudging groan of acceptance in return. She giggled at that response as she continued on, thinking about how her aunts had predicted her turn to tummy talk beforehand. It almost made her wonder if Fluttershy or Rarity had something similar going on inside of them. Speaking of which, the relatively silent feeling of the wilderness gave way to some interesting sounds. A sloppy sounding bubble same from beyond the bushes, accompanied by what sounded like giggles from two different mouths. On a rock nearby, some clothes lay strewn across it with bedazzled features. No doubt these belonged to Rarity, as she was one to show off with her latest creations while using herself as the model.

Removing her disguise and placing her threads along with them, she went to walk into the vicinity of the pit when a groan of epic proportions made her stop in her tracks.

That couldn't have been the mud bubbling, no mud bubble ever gets that loud. What is that?

Her curiosity getting the better of her, Cadance decided to do a little eavesdropping and stuck her head through the bushes quietly. On the other side, she was met with two large mounds of fat that sat on either side of her vision, one white and one yellow. With the holes she saw in the middle of each, it was obvious she was looking at the bellies of her hosts and it looked like they were in the middle of a conversation.

“So that's what you've been up to? Just eating the most vile and dangerous snacks known to ponykind just to make those noises come out of you!?” Rarity said, her voice filled with shock. Fluttershy giggled at her friend's pure bewilderment in her methods, the sight of her expression amusing her. The yellow pegasus was no doubt a hefty girl, the lower half of her two piece being practically swallowed by her butt and disappeared under her belly. Speaking of which, the yellow bulge was bigger than ever, taking up a good part of the hidden princess' vision as it sat between her large legs and supported the large breasts that were barely being held in her bra.

“Well, I did start on this trend much earlier than you did. The foods I mainly ate were big loads of beans, nachos, burritos and a salivating supply of soda to wash it all down. Only recently did I decide to expand my diet to include foods that would put a little more jiggle on my middle, so I've got a healthy supply of fuel to make some noise. This yellow blob of mine is a noisy one, especially after those lessons from the princesses about how to make it even louder. What you heard is just a little bit of what I can do.” Fluttershy boasted.

“Well, I hope I get to have as much fun as you someday. I'm still trying to catch up to where you are and I'm not even halfway there!” Rarity moaned. Cadance looked over and saw what she meant. Barely being restrained behind a yellow sling bikini was a mound of marshmallow fluff that made her look huge. The ratio from her calves to her thighs was almost unbelievable, the sheer amount of change as she traced her gaze up her waist was blistering. Her Cutie Marks were huge on her giant hips, sitting far off the side of the rock she chose to take up. Her belly was another thing to be impressed by, the blob hanging just as far out on her body as her breasts which were practically on full display with the strips of the bikini she was wearing covering only a tiny portion of her orbs.

“Oh don't be so hard on yourself, you're just as big as anypony else that's taking on this trend. And trust me, once you embrace your inner desires and let yourself go, you just might be able to make as much noise as me.” Fluttershy said. Just then, Cadance's belly rang out in a rumble that shook the bushes she was hiding in. The two ponies looked over and tilted their heads in confusion, the pink princess walking out with a red blush and a hand on her belly.

“Uh… excuse me.” She said sheepishly, getting a laugh out of the two waiting for her.

“Don't worry, Cadance. We've both had the moments where our bellies ring out in the most embarrassing situations. Besides, we're here to embrace that sound we just heard. Either way, it's good to see you!” Fluttershy said with a smile.

“I must agree. I've had that moment when I had my insides make me the center of attention by accident, especially after a stretch of non-stop sewing. It's nothing to be embarrassed by.” Rarity added.

“I suppose you're right, it's all natural in the grand scheme of things. But back to the literal big picture, you two are huge!” The two ponies stood up to address the princess’ comment and showed off their mass. Rarity stood up with elegance and grace that only she was known for, a hand on her hip to show how wide they were and another holding the side of her breast as if she were posing for a picture. Fluttershy was a different case, her larger gut carrying much more weight and causing her to have more sluggish movements. As a result, she mostly relied on rocking upright to get her going, her halted momentum once she was on her feet causing her belly to slosh around.

“Good grief, Fluttershy, how much did you pack yourself with?” Cadance asked curiously.

“Mostly liquids now, very carbonated liquids. Eating the food I do can easily uh…. Back things up, so I need a solution to help break things down. Soda, Seltzer water, the occasional glass of aged wine, basically anything worth its salt in bubbles to make sure I'm still good to eat.” She stated proudly.

“Well, looks like we have a pioneer on our hands.” The princess joked, getting Rarity to giggle a little. Looking out to the awaiting mud pit, the princess saw everything she could have imagined. Bubbles rose up and popped like a cauldron of sludge, mud splattering on the surface before melding with the thick substance once more.

The mud pit was as expected, a viscous puddle of muck that looked like a fun place to sit and relax. But one thing stuck out to the Princess of Love. Over on the other side, just in her field of view was a small trickle of water dripping into the pit.

"Is that a water spout?" Cadance asked.

"It is. It's to help us move around in the mud better. Even if we weren't this big, this mud pit was always a bit of a chore to relax in because of the pressure of the mud on my body. So, to ease the discomfort and grant us more freedom of movement, I mixed in some extra water to make the mud just liquid enough to move around but still thick enough so that it isn't just muddy water." Fluttershy explained, smiling at her own ingenuity.

“Such creative effort should be commended, Fluttershy! If I could have come up with that, having a mud pit would be the biggest fad in Equestria!” Rarity said. “But, some things are better off left to the select few who come up with the ideas. Speaking of which, we're all here now. What exactly are we doing?”

Cadance snapped her head around and quirked an eyebrow. “I thought you knew what we were doing?”

“I wrote the invitation, but I didn't know everything about it. All I knew was that mine and Fluttershy's larger frames were not made for the usual spa treatments anymore, so she suggested we come here as a substitute. Everything else I could have asked about this was left either vague or not said at all.” The two other ponies looked at the yellow pegasus who now wore a pink shading on her muzzle.

“Well, as you two may already know, we've all been coached by the Royal Sisters on the basics and intentions of being able to cause Belly-quakes. I myself have been a big fan of using this new skill to my advantage when it comes to fun and personal pleasure, so I had both of you fill up on snacks before you came here so that we could all get into the mud, down some of the orbs that the princesses graciously game me the recipe to and see how the mud makes us feel one we cause some waves.” Fluttershy said, catching the two other ponies off guard.

“A Belly-quake in mud? I'd have never imagined going as far as to submerge myself in mud and to it. Perhaps this is a chance to experiment and see where we can go with this idea. Besides, a little mud bath is nothing I'd shy away from.” Rarity said.

“I agree. We've all had a chance to see what the raw power can do, so why not see what it can do below the murky muck of this pit. Plus, I'd be lying if I said I didn't like listening to my tummy rumble. So I say, tally ho!” Cadance said confidently. The others nodded and decided to start their little treatment. Cadance stepped in first as she was the guest of honor, the coolness of the mud making her shiver a little. The feeling of the mud was nothing she wasn't used to, but the cold of the sludge was nothing like the magically heated mud bath that the Crystal Empire's spa held within its walls. Regardless, she waded her way through it until the gunk was up to her belly button.

Next came Rarity, who carried less of a newbie stride and more of a confident strut into the pit. Each squish of mud lowered in pitch as she waltzed in, her belly slipping down into it like a ball of rich blubber as it was pushed in a little before she stopped just next to Cadance.

Finally, Fluttershy made her move into the pit. As she stepped in, her body jiggled as she made her way to them, the occasional Blorp filling the air as her massive gut hit the surface before even her rear was down in the mix. Striding deeper into the muck, her belly button became level with the mud and like a cup in a river, the mud progressively filled the empty space until it was submerged in mud and she stopped in front of her guests. They decided to get down on their knees in the mud and see where they stood in the mud, the mounds that were their chests practically floated on the surface of the mud. Cadance found the floating breasts quite amusing.

“Our chests are floating like pool toys!” she giggled. The other two mares looked at their respective mounds. Rarity took particular interest in the sight.

“I must say, that’s quite a spectacle.” She said. “It makes me feel, oddly enough, like it enhances my sex appeal.”

Beneath the surface of the mud, the mares’ bodies were shifting around on the dirt floor, unintentionally digging them deeper into the mud until their breasts were in the mud as well, leaving them above the mud from their shoulders-up. The three girls all sighed contently as the murky muck seemed to make them much calmer than they were before, the slowly warming substance acclimating to their body heat and making them relax.

“I don't know what it is about this mud, but it feels amazing.” Cadance sighed. “The mud we have at the spa in the Crystal Empire is very special. Handcrafted and manufactured to soothe every area and heated using fire incantations at the bottom of the pool to add to the mix. But this, the natural feel of the real deal… it's so… exotic.”

“Indeed,” Rarity added. “I may be a mare who likes to associate herself with the more ‘High Class’ amenities, but sometimes soaking in a bit of mud can truly allow me to relax.”

“So true. Come on, there should be some rocks under us that will allow us to sit comfortably in the mud.” Fluttershy directed them to another area where there were indeed three spots perfectly fitting their criteria. Sitting in the mud, the mares felt their muscles relax, every fibre of their being being taken on a soothing ride down what felt like a lazy river as they kissed the stress goodbye and let themselves be taken over by bliss.

–

One Hour Later…

It had been a while since they had started soaking in the mud. Fluttershy had taken the time to apply some to her face as a mud mask a while ago, Rarity following suit shortly after and Cadance choosing to opt out. The mares had become so relaxed that they were starting to nod off, each of them trying their hardest to keep their eyes open. Suddenly, Cadance felt something moving beneath the surface of the mud.

“Hey, are there any creatures other than us in this mud pit?” Cadance asked.

“No. Not even my animal friends are allowed back here. They know that this place is reserved for me and others who just want to get away. Why do you ask?” Fluttershy said with a confused expression.

“I was just asking because I feel something moving under the mud, like something wiggling near my body. Do any of you feel it?”

“I do feel the mud rippling a little, but nothing moving like an animal of any kind.” Rarity said, the yellow pegasus also being left confused. Then, Fluttershy had a moment of realization.

“I think I know what it is.” Fluttershy said. “It’s your tummy rumbling.”

“Do you think so? I haven't heard a peep from down below.” Cadance said.

“That’s because of the mud muffling the noise.” Fluttershy said. “It’s too dense for sound to travel.”

Cadance thought about it for a moment and was in agreement. “I'd never considered it. Maybe…”

She reached down into the mud and felt her belly. To her shock, she realized that Fluttershy was right. Her belly was rippling under the mud, and she was none the wiser.

“She's right, I can feel my belly shaking! I guess I've gotten used to eating so much and using the orbs my aunts gave me that I forgot what it feels like to have my belly rumble in actual hunger.” She giggled. Rarity soon felt a similar sensation.

“Ooh, I think mine is getting growly too. I guess we've been sitting here for so long that we got hungry.” Rarity said. Then, they all heard a very faint, muffled growl.

“And there goes mine.” Fluttershy said.

Cadance stood up a bit to reveal her mud-covered body. As she stood, the mud slid off her chest and legs with a little caught in her wings and mane. Her belly shook violently as it voiced its hunger unmuffled.

“Oh, would you quiet down!?” She huffed, surprisingly getting cooperation out of her belly as it stopped groaning. For five seconds.

“Oh my, it seems we've been here for longer than we'd all anticipated. Cadance's stomach sounds menacing!” Rarity said, standing up herself, which revealed the sounds her belly was making. She held it in her hands as it growled, ripples of white fat covering it entirely.

“Mine sounds menacing? You should hear yourself.” Cadance said cheekily, Rarity blushing as she was called out. Then came Fluttershy, who's belly was still slightly audible under the mud. She began to stand up, mud slowly running off of her from shoulder to chest to her big wings. Then, the yellow mass came above the surface. It practically roared before them, the big blob rumbling like an earthquake.

“Oh dear, I guess I am a little hungry.” Fluttershy said casually.

“A LITTLE!?” The other two said loudly, getting a laugh out of her.

“Don't worry, I came prepared. I have some food for us to munch on without having to leave our spot. And just to be clear… it is a big amount.” Fluttershy said. Reaching behind her, she revealed a rope that led onto the bushes. The other two ponies were slightly confused about what this rope was for as Fluttershy pulled on it and the sound of rattling wheels came from behind the bushes.

Then, that's when they saw it. Coming out from beyond the greenery was a mountain of food, stacked high and large on a cart with everything they could have ever wanted. And somehow, it was all supported on a set of four shopping cart wheels. They stared up at the pile, Rarity and Cadance in shock and Fluttershy just smiling.

“This is the little food stash I kept hidden away in case I ever got hungry while back here by myself. Like I said before, ever since I started gaining, my appetite has been growing non-stop. Likewise, so has my food supply. And like Cadance said, I have one big belly to hold it all! But since you two were coming along, I packed a little extra.” Fluttershy explained. She then rubbed her belly as it started growling again.

“This is extra on top of what you can eat!?” Cadance said, still in relative shock. “I'd have thought you were inviting ten if I'd seen this on the way in!”

“Me too! How can you eat so much and not get sick!?” Rarity asked.

“The orbs the princesses gave us.” The two shocked ponies looked at each other confused. Then, Fluttershy reached for the cart and pulled a bag of the small things out from the bottom. Cadance recognized the orbs from when she and her aunts were testing them, but they looked… different. Instead of being one solid color, these ones seemed to fluctuate in shade from a dark green to a light grass green, decorative bubbles on the surface.

“These orbs are very special. These orbs are specially made to be an aid in helping me digest. I like to call them Gurgle Balls.” Fluttershy giggled. “After I munch on a big load of food, I swallow one of these and I get what is basically a rapid release pill that kicks up my digestion and allows me to eat so much.”

“Seems fairly simple. But why call them ‘Gurgle Balls’?” Cadance asked.

“Well, like these orbs were originally made for, the only side effect of them helping my tummy break down food is making it rather rumbly while it does so.” The yellow pegasus blushed. Cadance and Rarity looked between themselves and the pile of food on the side of the pit.

“That is more food than I've eaten in a week even with how big I've gotten. Should we even do this?” Rarity asked.

“I don't think the question is should we do this, but could we do this? With how our tummies were growling, I think we could.” Cadence said with a confident smile and her hands on her belly. Rarity looked down at her own tummy and felt its softness, a gut trembling burble shaking the surface as if it was tempting her. She listened to it bubble and gurgle, the sounds making her mind erase itself like it was manipulating her mind.

Soon enough, she couldn't remember what she was concerned about and smiled as she licked her lips.

“Perhaps my judgement was dealt too quickly. I do think that this looks rather delicious and our stomachs are making a rather big fuss over it. I suppose we should listen to our inner voices and indulge in this mountain of delectable morsels.” Rarity said with a bit more vigor than she had before.

“Well, I guess both we and our bellies are in agreement! So, where should we start with this mountain of food?” Cadance asked.

“With the one thing that helped me start it all…” Fluttershy pulled a pallet of familiar wrappers out from the pile and said…

“Hayburgers!”

“Oh great! I haven't had one of these in ages! And these look like Mega Hay-Bacon Specials!” Cadance said excitedly.

“That's because they are! The greatness of these special burgers gave me the starter I needed to get into the gaining scene, not to mention getting my tummy growling with how hard they were to break down. So I think these will be just as good for us as they were for me.” The three mares sank down into the mud again and sat next to the cart on the edge, propping their arms up on the edge to give them some support. Cadance, Fluttershy, and Rarity all grabbed one and unwrapped their prizes.

“Oh my days, these look so good! If you'd told me a few weeks ago that I'd be willingly eating fast food for the fun of it, I'd have called you insane!” Rarity admitted.

“Well, you were rather dramatic when you first saw me after I took my time to plump up. Did you seriously have to say that I looked like a yellow jelly mold?” Fluttershy deadpanned, the pink princess next to her giggling into her hand while the white unicorn blushed.

“I will admit that my reaction to your choice was a bit over the limit of what I'd usually say. But I've grown to understand what the love behind this behavior was, both being big and hearing your tummy growl. And I did apologize for that, you know…” Rarity huffed.

“Of course you did… after three days.” Fluttershy snorted back, Cadance one again being thrown into a giggle fit. She then refocused on the objective and directed her attention to the burgers in front of them.

“Well, no use in delaying the inevitable. Ladies, shall we dig in?” The yellow pegasus asked. With a nod from the others in her group, they all partook in a simultaneous first bite, all moaning in satisfaction as the taste overwhelmed their taste buds and led them to fill themselves up with the large amount of food that they had been so graciously given.

–

Another Hour Later…

After a good bit of eating and chatting about how their experiences were going, the three mares were now sunk into the mud again and were leaning up against the wall of the pit. The cart had been emptied of its contents, only a few crumbs and scraps being left behind after being raised by the three big mares. The sound of moaning did fill the air around the pit, but it did not come from any tummy.

While Fluttershy was used to eating so much, her guests were not. Rarity and Cadance sat low in the mud, their eyes closed and very strained expressions on their faces. They'd never eaten so much in their lives, even after having been in the game for a decent amount of time. They both were encouraged by their bellies to push harder than they did before, mostly because of the growling but partially because of wanting to prove to their host that they could get just as big as her. But, they came up just a little bit short.

Rarity moaned as she sat with her shoulders just above the surface. “Oh my… I don't think I've ever eaten so much in my life.”

“You and I both. We alicorns may have a bigger appetite than the average pony, but even we have our limits. I guess I still haven't gotten to that stage where I can just eat as much as I want yet. Auntie Luna was the biggest that I'd seen out of my aunts, so I suppose she's been doing it for much longer. Even so, I think I ate a fair share.” Cadance said, a little weak in her speech as she tried to let her body ease the strain away.

“Don't worry, girls, you'll get there eventually. You just need to push yourself like you did today. After this, you'll definitely find yourself much bigger and much hungrier since you ate so much. I've just gotten used to it over time.” Fluttershy said, her encouraging words getting the other two ponies in the pit to feel much more confident and squeeze a smile out of their stuffed bodies.

“Now that we've eaten to our limits and beyond that, we can now get to what I think is the fun part.” the yellow pony pulled out the green orbs from before and smiled. “These oughta help you two clear up some space. Plus, it'll give us that feeling we felt when we first got hungry since we're in the mud again. So take one and toss it back.”

They each took one and observed them. Cadance especially took her time to look these new orbs over, having never seen them before. “Y'know, my aunts never said anything about these. You said these were specially made for you. Who made them?”

“Well, they aren't exactly made. They're more… modified.” Fluttershy said. “Along with Pinkie, who also wanted to change up how her orbs reacted, we both went to Zecora that gave us some simple knowledge in the ways of modifying their effects. Just a simple potion that we dip the orbs in for a few seconds, wait for the associated color to flash in the liquid and presto! A new type of Tummy Treat specifically made to please whoever needs it.”

“Wow, that's very interesting. I don't believe I've had a chance to see if I could modify mine.” Rarity said with a hint of jealousy.

“I wouldn't see myself modifying the orbs I make, but this does seem like something that could be a future endeavor. But for now, let's down the ones in front of us because I still feel a little tight in the tummy.” Cadance said with a strained voice. She massaged her belly a bit.

The three mares tossed the green orbs back and swallowed. Each one of them felt the orb hit the center of their bellies, idly waiting for a reaction.

“So, how long does it take to usually feel the reaction start?” Rarity asked.

“Just a couple of seconds. It'll start at different times depending on who eats them. Could be an instant reaction, should be delayed a little… But once it happens, it'll surely make the same feeling we felt before we started eating. And it should be even more potent too.” Fluttershy explained. They all waited for their time, sitting with their shoulders just above the mud as they settled in.

Cadance was especially excited for this little reaction, wanting to see just what it did and if she wanted to make some of these orbs herself. The prospect of having these orbs ready in case she was feeling a little too full was an interesting thought, even if she may not use them often. She soon felt them start to kick in.

She felt the same wiggling feeling begin to arise from below, a little more intense this time thanks to the orbs. The surface of the mud began to visibly ripple this time, indicating that she was now feeling the effects.

“Ooh, I think I feel something under the mud. Is it working?” Cadance asked, Fluttershy nodding in confirmation.

“No doubt it’s working now, especially since I can see the waves it's generating. Feel it and see!” Cadance placed her hands down into the mud and she felt a lot of movement on her belly. She was honestly surprised she couldn't hear it with how much she could feel the orb working. On top of that, she started to feel a lot less strain in her middle.

“Wow, it's really working! I feel so much lighter now. I'm surprised it's not somewhat audible with how violent it feels.” Cadance said.

“Mud density, remember?” Fluttershy said with a smile.

“If that's the case, then how come we could hear yours?” Rarity chimed in.

“Mine was louder, just that simple.” Fluttershy said. “Besides, the orbs I ate had to be bumped up in reactivity because of my belly's size. Yours are just what they were before I changed them. Speaking of which, you should be feeling something now too, Rarity.”

And indeed she did. Just as Fluttershy spoke, ripples began to appear near her body.

“Oh my, you were right, these things are potent. I can feel it shaking my body without even touching it.” Rarity said. “If this is how it reacts with us, I can't imagine how it will react to you.”

“Trust me, it is a good feeling.” Fluttershy said. A few seconds later, she felt her own belly. As expected, the reaction was much bigger than the others. Once again, a muffled burbling could be heard from her gut under the mud, much louder and more noticeable than last time.

Soon enough, the three mares were all feeling the burn. Or bubble, as the case may be. Each one was feeling a different level of potency, all much more intense than they'd felt before. Rarity felt hers lift her up a bit and Cadance felt hers lurch forward.

“It really is kicking up a storm! At the same time of me feeling lighter as it does its work, I feel the weight of just how much work it's doing inside of me.” Cadance said.

“And this isn't even the full effect, just give it a bit. It'll start to slowly ramp up. But for now, why don't we have some fun while it's happening?” Fluttershy suggested.

“What do you have in mind?” Rarity asked.

“We've already seen what happens when our bellies are fully submerged. What about if we let them come above the surface and see what we can hear?” Cadance and Rarity looked at each other, nodded and decided to play along. They decided to go one at a time and tested each one of them.

Cadance was the first to rise from the mud, coming just above the surface to let her belly be heard while sitting on the edge of the mud pit. A deep grumbling came from her belly as the mud slipped off her body, deep enough to sound almost animalistic.

“Now that is definitely louder than before. It's almost predatory with how loud it is.” Cadance exclaimed as her belly jiggled. A few seconds later, it changed its tune. The deep grumbling then turned into a bubbly gurgle that only a volatile cauldron stew could accomplish.

“Looks like you've found out why they're called ‘Gurgle Balls’.” Fluttershy giggled as Cadance blushed a little. Rarity then decided to take her turn and rise up from her spot. She decided to let herself rise up on her back and float to the surface in her own way of showing off. Her belly looked like a marshmallow island on a sea of hot chocolate, but that island seemed to have lost its voice for the moment.

“Hmm, it seems that my tummy has gone silent. Perhaps I can coax it back to life.” She spoke.

Rarity gave her belly a jiggle. Along with her little bit of coaxing, a girthy growling took over the air, causing her little tummy island to wiggle and the mud to ripple.

“That little island seems to be going through an earthquake. Might want to evacuate any inhabitants for fear of being swallowed by the growing sinkhole.” Cadance said, lightly poking Rarity's belly button. The fashionista giggled as her middle was lightly tickled by her touch.

Fluttershy found it amusing herself, though she had yet to show off her own power. She wasn’t that competitive to begin with, but she was about to show the fruits of being in the game so long.

“The effect the orbs have on the two of you seem to be just as big as when I first got them. But I've been doing this a little longer, so I think I have the upper hand in this belly battle.” Fluttershy said as she rose up slightly, the very top of her belly poking out while the rest stayed submerged, a little tease as to what was coming. Her orb started to kick in.

The reaction started out small like the others, a small grumbling making what part of her belly that was visible start jiggling and the mud ripple. She stayed relatively still while the orb did its thing, the pitch and tone of her belly changing ever so slightly every few seconds.

“See, I've got a little bit better of a reaction out of this one. But like I said earlier, they're going to start ramping up soon. Our bellies will all be making a decent rumble soon, making them even more jiggly than they are right now.” The canary yellow pegasus patted her belly.

“Really?” Rarity said with a hint of concern. “How much will it ramp up?”

“Let's just say… you'll be wondering if it's your belly or a Grizzly Bear nearby.” Fluttershy said slyly.

“Since when did you get so cheeky, Fluttershy?” Cadance asked, an eyebrow raised in an interrogating manner.

“Me being so big has given me the confidence to be a little more bold. It feels good to let a little bit of my attitude flare up when I want and not immediately feel sorry.” She said. Then, a deep rumbling came from Rarity that made both of them look over. Her marshmallow-like belly rippled in a manner similar to that of a pond that had its surface disturbed.

“Oh my. I believe mine has officially started to ‘Ramp Up’, as you called it. My tummy feels like it's being shaken all over the place.” The white unicorn stated. Fluttershy then felt hers start to move, a growling much the same to Rarity joining in. She caressed it gently, almost treating it like a pet.

Cadance was about to question what was happening around her when her own pink belly began to quiver, a thunderous bubbling taking over her previous thoughts.

“Ooh, I can feel that everywhere. Our bellies are just so noisy now. I don't think we're even worried about the fullness we were feeling earlier. Now, we're just enjoying the noise. Speaking of which…” Cadance offered a hand to Rarity, the white unicorn graciously accepting the gesture and let herself be pulled upright while shaking some of the mud out of her mane. A smile adorned the pink princess' face as she gained a grip on the jiggling mass that was Rarity's middle and pressed it against her own. The two bellies seemed to be having an argument, pushing against one another like they were trying to settle a bet.

“It seems our bellies are fighting about something. What do you think they're getting fussy about?” Cadance asked while giggling.

“Perhaps they're trying to see which one is louder out of the two of them. Honestly, it isn't even a contest considering who else is here.” Rarity gestured to Fluttershy. The yellow pegasus rose up further and sat on the edge, showing off her entire body along with her belly. She began to rub it slowly, trying to coax a reaction out of hers and succeeded. The butter-colored orb vibrated erratically.

“Good girl, mama's so proud.” Fluttershy cooed. Rarity and Cadance giggled a bit before they separated and felt another twinge of hunger build up within them.

“Hm. I'm starting to feel a little hungry again. Anypony else?” Cadance asked, Rarity and Fluttershy nodding in agreement.

“Perhaps we should have another spot of food to settle that hunger? Preferably something we can test our limits with?” Rarity asked, looking over to the yellow pegasus expectantly. Fluttershy smiled and grabbed hold of another rope next to her.

“Oh Rarity, you know me too well…” She said, pulling out another kart from the bushes with just as big of a pile as the last one. The three mares all felt another growl of hunger from their stomachs and looked amongst each other with smiles.

“I always keep another load ready just in case.” Fluttershy said as they all began to grab at the kart’s contents to begin again on what would be a nice afternoon for the three of them.
