Hypno-Tummy

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.
