As Pinkie Pie led her five friends to her home of Sugarcube Corner for the party, she grew so excited within herself. Most of her parties involve the usual games, snacks and loud music, which she had always enjoyed since she earned her cutie-mark consisting of balloons. However, this party was going to be different from all the others, as for her own amusement, she secretly placed hoses within six of her cupcakes, each of which attached to large helium tanks. She enjoyed balloons, but she always wanted to turn her friends, and even herself, into balloons, simply because of how big yet soft and squishy they are.
"Ya know, sugarcube," Applejack said to Pinkie, walking down the streets of Ponyville, "there ain't nuttin' to celebrate in yer party. So why interrupt our busy schedules for the sake of that there party?"
"Oh, there is something to celebrate!" Responded the pink party pony. "I'm celebrating my friendship with you, because it's always fun to be hanging out with my five bestest friends in all of Ponyville!"
"I'm supposed to be practicing my flight maneuvers," Rainbow responded sternly, "so that I could earn my spot in the Wonderbolts. I go to that party, and I'll be wasting my time!"
"Mind your manners, Rainbow," Rarity scolded the light-blue pegasus. "You are Pinkie's cordially invited guest, and you are expected to be polite to your party host. Besides, I've worked long and hard at my Carousel Boutique shop, and I thought I earned some bit of rest and relaxation. I'm sure that you are likewise, always exhausting and even outright injuring yourself to practice those dangerous flight maneuvers."
"Hey!" Rainbow talked back. "I know how to handle myself in dangerous situations! I've practiced stunt flying all my life, and have gotten used to all of my past injuries. Your concern is misplaced!"
"Can somepony please stop fighting?" Twilight Sparkle interrupted Rainbow and Rarity's argument. "We're invited to another one of Pinkie Pie's parties, which means we're supposed to have fun, not take our problems out on each other like we normally do."
"But..." Rainbow objected.
"I second Twilight's comment," the white fashion unicorn responded. "Once we come to our darling Pinkie's party, we are going to have fun and relax from a long week of work. I'm sure it's what Pinkie would want."
"You..." Rainbow facehoofed. "...Okay. Besides, practice gets boring after a while."
"I just hope the party is not too loud or disruptive," Fluttershy said to the others. "And, I also hope there aren't any crowds, either. I-I'm just not used to crowds... if you know what I mean..."
"Oh," Pinkie responded to her yellow pegasus friend, "don't be such a worrywort! Mr. and Mrs. Cake are out giving their babies a stroll, so it's just going to be the six of us celebrating our friendship!"
Eventually, the six mares arrived at Sugarcube Corner, as they entered and walked upstairs to the party room. Within there was the usual assortment of balloons, tables full of food and drinks such as cupcakes, crackers and fruit punch, as well as an old record player playing some pop-music, and games such as Pin the Tail and Spin the Bottle. "Wow," Twilight said, "once again, you've outdone yourself this time!"
"No need to thank me," Pinkie blushed. "Besides, it's the least I could do for my friends." The least I could do, indeed, Pinkie thought to herself, as she secretly made a sinister snarl.
"So," Rainbow said to her pink host, "what's the first agenda on the list?"
"Well," the pink party pony responded, "there are some cupcakes on the table, if you would like some. I know I would, myself."
"Good," Applejack said, "'cause Ah'm famished!"
Pinkie's friends ran toward the table, as they took their first bites on their given cupcakes. Meanwhile, Pinkie made a sinister snarl on her face, hoping that they don't look at her. Very soon, my friends, Pinkie thought to herself again, you'll all be so much 'bigger' for me.
"Mmm..." Rainbow said underneath her eating. "This cupcake isn't so-"
Suddenly, the cerulean pegasus noticed something surprising. First, she was shocked to discover a hose within her mouth, as it she then saw it connected to what appeared to be six compressed air tanks. Secondly, she could feel a strange, tight pressure in her belly building up within her, as it started to bulge like a balloon after first inflating. Lastly, it wasn't just her who was experiencing this.
"What's going on," Twilight muffled, as she also discovered a hose within her mouth.
"Wait," Rainbow muffled, looking at the other girls. "You, too?"
It came as another surprise. Rainbow, Twilight and all three of their friends all had hoses in their mouths, as their bellies were gradually being inflated by air tanks.
Their bellies started out tout and small, giving the impression that they look pregnant. Very soon, though, those bellies encompassed the size of their bodies as they touched the ground. Then, they had grown so big, that they could no longer touch the ground with their hooves. They could feel so much pressure building up in their bellies, as they grew larger and tighter, while making loud, creaking noises. "Pinkie Pie," Fluttershy muffled to her pink friend, "what's going on? Why are we inflating?"
"Oh," Pinkie said, smiling to her friends. "Don't mind me. I've sorta... hid those hoses inside some cupcakes, so that by the time you eat them, you start becoming balloons, like the ones on my flank."
"Gosh darnit!" Applejack muffled, as she and her friends became larger than even the giant snack table. "Pinkie, get them hoses outta our mouths, or yer gonna regret it!"
"Aw, come on!" Pinkie responded, able to understand the orange farm-pony's muffles. "You're so adorable when you're big and inflated!"
"Mmph mmph!" Twilight screamed underneath her hose. The girls struggled to get their hooves back on the ground. Unfortunately, they were immobile. While the rest of their bodies were normal sized, it was their bellies who grew to nearly the size of the entire party room, as if they looked like they were pregnant with over one thousand foals. They stretched to the equivalent of rubber, and refracted lights from the windows while becoming so transparent, that they could see through their bellies. Already, they could feel their bellies stretched to their limits, unable to hold out for much longer before popping.
"Now, it's my turn!" Wanting to join in, Pinkie ran to the air tanks, as she placed a dormant hose within her own mouth, and turned on the pressure. Very quickly, she could feel her belly building up pressure, as it bulged to the size of a pregnant mare's belly, but then stretched to the same size of her body, followed by the near size of the snack table, and then nearly half the room like her friends. Already, she could feel so much air within her belly, as it also became shiny and transparent.
Very soon, all six of the girls were crammed in the same room, unable to escape from their inflated forms. With the exception of Pinkie, the other five girls were desperate to escape. They tried everything they could to get the hoses out of their mouths, but they were stuck. The hoses were probably covered in glue to keep them inside their mouths, so that Pinkie could inflate them for her own amusement. Pinkie, on the other hoof, didn't seem to mind, herself. She enjoyed the feeling of being crammed inside such cramped space between her inflated friends, while her belly became tight and massive, near bursting yet at the same time as soft, squishy and cuddly as the other mares. And, the best part for her is that she gets to cuddle her inflated belly with those of all of her friends, as they are as together as any group of friends would be.
Unfortunately, before Pinkie could continue snuggling her giant belly with those of her friends', suddenly she saw the walls and ceiling around her starting to crack. They became unable to withstand the tremendous force of their stretching bellies, while the air tanks started blowing out of control. The walls and ceiling caved in, causing the top section of Sugarcube Corner to be broken apart almost entirely from the inside-out.
"Please... stop those air tanks," Rainbow Dash muffled underneath her hose, scared of eventually popping.
"I don't want to pop!" Fluttershy muffled as well, wanting desperately to remove the hose from her mouth, despite the fact that she couldn't.
Very soon, all the denizens of Ponyville saw what appeared to be six shiny, transparent over-inflating balloons, each resembling the six ponies. "What in the hay?" Said a stallion, as he dragged a cart full of barrels around.
"Are those balloons getting larger?" Said a young mare. "In fact, don't they slightly resemble ponies?"
"Run for your lives!" Screamed another mare, scared out of her wits over the idea of six inflating pony balloons. "They're gonna blow!"
All the ponies of Ponyville then started running away from the pony balloons, struggling to find shelter before they explode.
"Somepony," Twilight muffled silently, closing her eyes while awaiting her death by popping. "We're going to explode."
"Get them air-blowin' hoses outta our mouths!" Applejack muffled, unable to escape the pressure.
At the local elementary school, Applebloom, Scootaloo, and Sweetie Belle were playing on a merry-go-round, having fun and minding their own business. However, they jumped off after their attention was caught by six giant balloons the same colors as Applejack and her friends. "What'n tarnashins?" Applebloom asked, confused by the sight.
"Is that my big sister?" Sweetie Belle asked, befuddled by the idea that the white, over-inflating balloon was her older sister, Rarity.
"Why is Rainbow Dash... huge?" Scootaloo asked.
"Oh no." Applebloom became scared. "Mah big sister's gonna blow, 'long with the rest!"
"Everypony, run!" Scootaloo called out, as she and her Cutie Mark Crusader friends rushed to the nearest hillside for hiding, hoping to not get caught in the blast radius.
At Twilight's library, Spike was sweeping the floors as usual, when he heard strange hissing sounds coming from outside. He ran outdoors to figure it out, only to see what appeared to be six balloons in familiar-looking colors. Spike then saw from afar Twilight Sparkle, as she and her friends still had those hoses attached to their mouths, inflating their bellies to massive proportions. The girls were helpless underneath the pressure of their inflating bellies. "Oh no." Spike became horrified of his own friend inflating to near bursting. Instinctively, Spike ran as far away from the pony balloons as possible, just to save his life.
On Sweet Apple Acres, Granny Smith was sitting on her rocking chair on the farmhouse's porch, while Big Macintosh was still plowing the fields for gardening. They then heard the sounds of hissing coming from town, as they turned around to see six giant, inflating balloons, all of which were in such familiar colors. "Oh, hay..." Granny never imagined that her granddaughter would actually inflate to massive sizes. Before she could finish her thought, however, Big Mac used his teeth to grab his grandmother by her ascot, then drag her into the farmhouse for safety from the ensuing explosion.
Around the same time, Mr. and Mrs. Cake were pushing a two-seated stroller carrying their twins, Pound and Pumpkin. They were unable to mind their own businesses, due to all the ponies frantically running the opposite direction from where they're walking.
"Gah gah!" Pound and Pumpkin cooed, befuddled by a strange site in front of them.
"What in the hay?" Mr. Cake said, as he and his wife saw, to their horror, six balloons in the same colors as Pinkie Pie and her friends, over-inflating to encompass most of Ponyville.
"Pound, Pumpkin," Mrs. Cake said to her children, as she turned the stroller to the opposite direction, "close your eyes and cover your ears." The Cakes then desperately ran the other way, hoping to protect their children from the massive blast.
At Fluttershy's cottage, all of the animals, including Angel Bunny, were frolicking as usual, with nothing on their minds. Then, they were followed by a loud hissing sound. The animals turned to Ponyville, and to their horror, saw what appeared to be a giant, yellow and over-inflating balloon, alongside those of lavender, light-blue, pink, orange, and white. At the top of the yellow balloon was Fluttershy herself, her belly actually attached to the balloon while her friends are attached to theirs, implying that the balloons are their bellies. With no time to comprehend, all the animals ran from Fluttershy's cottage to the Everfree Forest, hoping to find shelter from the ensuing explosion.
The six balloons that were supposed to be Twilight and her friends soon encompassed nearly half of Ponyville. The girls couldn't take any more of the massive pressure building in their giant bellies, as they closed their eyes and prepared for what appeared to be their inevitable ends...
KABOOM!!!!
From the explosion, came a mass of confetti the same colors as the girls. So much of Ponyville's buildings were ravaged and torn apart, as if a giant magic missile dropped on the town. The ponies who ran and hid from the blast then slowly crawled back from their hiding spots, seeing the place where the six pony balloons used to be before exploding, while they were being covered in the falling confetti. So many of them were confused by the idea of six mares inflating to massive sizes and then popping.
The Cutie Mark Crusaders got themselves out of the hill they hid behind. Next to them, the schoolhouse was torn about by the explosion, and they became flabbergasted over the idea that Rarity, Applejack, and Rainbow Dash inflated and popped. "Is Applejack..." Struggling to push aside the thoughts of her sister dying from the explosion, Applebloom started to tear and mourn for her sister's alleged death. All Sweetie Belle and Scootaloo could do was wrap their forelegs around her shoulders and comfort her.
Twilight's library was torn all the way down to its base, as if it no longer exists. Spike walked away from whatever hiding spot he came out of and back to the library, confused by all the confetti that probably used to be Twilight and the others. Back on Sweet Apple Acres, Granny and Big Mac walked outside of what used to be their farmhouse before the explosion. They were taken aback over the idea that one of their own family members, Applejack, exploded from over-inflation, alongside her friends. Even Mr. and Mrs. Cake, still in Downtown Ponyville, were shocked over seeing what could possibly be Pinkie and the others popping, despite their babies apparently having fun with the raining confetti. As for Fluttershy's animal friends, they slowly walked away from cover and saw confetti raining on them. They asked themselves, how could Fluttershy inflate herself and pop, alongside her friends? Thinking that their caretaker died, they could do nothing else other than mourn her.
Or, so they and the rest of Ponyville thought...
***
"Ugh..." Groaned Twilight. As she awoke back to her senses, she saw herself on the ruins of what used to be Sugarcube Corner, as her five friends slowly regained consciousness of their own.
After fully awakening with her friends, Pinkie then said in an excited tone, "Wow, wasn't that fun? We became balloons the size of Ponyville, and then we popped! And, before we popped, we felt so snugly and squishy when crammed in the same room while inflated! Weren't we such adorable friends when inflating, even to bursting? Though..." She then looked at her belly again, which was mended back to normal as if it didn't pop. "Hey, my tummy!"
As she faced her friends, she saw them display anger and contempt to her, as if she was going to be punished for something.
"Pinkie," Twilight said to her pink friend, stern. "Right after we exploded from over-inflating, I've cast a spell that mended our stomachs to normal, right before I could slam into the ground and enter a coma, afterward."
"But other than that," Rainbow said to Pinkie, flying next to her with her pegasus wings, "you almost had us killed, and destroyed half of Ponyville, just to satisfy your sickening desire to get all six of us inflated to popping!"
"Ah knew that this 'ere party a'yers didn't celebrate nuttin'!" Applejack commented. "'Celebrate our friendship' 'ndeed..."
"Aw, come on girls." Pinkie blushed and chuckled nervously, not wanting to incite her friends' wraths any more than she had. "I just happened to... you know..."
"There they are!" Called out a stallion's voice. The girls turned around and saw what appeared to be an angry mob of Ponyville's denizens, showing so much contempt for what they did to them. The girls joined Pinkie in her nervousness as they slowly backed away from the crowd.
"Um," Fluttershy said to the mob. "W-we can explain..."
"No," said Mayor Mare amongst the crowd. "You don't need to explain."
"Psst," Rarity caught Twilight's attention. She then whispered, "Twilight, any advice?"
"Uh..." The mob slowly walked toward the girls. "RUN!" Twilight called out to her friends, as all six of them get chased by the angry mob, who desire nothing more than revenge for destroying half of Ponyville with their over-inflated, exploding bellies.
Author's Note
Ever since Spike inflated Applejack in "Spike, At Your Service," somepony had to eventually write a fanfic that has her and all of her friends inflating to bursting. This was why I wrote this fic, because I actually enjoy the Mane Six when their bellies are inflated to bursting. Once it passes submission, I actually can't wait to submit this to Equestria Daily, next.
Also, I've originally wanted this to be rated Teen. Unfortunately, even while I made it as safe as possible, in the end it was still fetish-based material, and I had to change the rating to Mature to reflect that. Whereas Spike inflating Applejack was intended as an innocent, two-second gag, my fanfic inspired by that one gag lasts the entire story and is more intended as fetish fuel. So yes, I've intended it to be fetish-fuel, because I have a pony inflation fetish, and always wanted to see the Mane Six inflated until they burst.
