Dear Twilight Sparkle
Haha, just kidding! It’s only me, Pinkie Pie! Who said formal always had to be what was used for letters huh? Anyway, I’ve got some new party supplies I want to try! Some really huge balloons for one thing! Can you meet me in Sugarcube Corner as soon as you can? There'll be cake, promise!
P.P.
Twilight smiled and tucked the letter into her saddlebags. Sure, why not? It was always interesting at the very least helping Pinkie Pie. Party supplies seemed harmless enough. Although she thought back to her previous experience dealing with her bouncy pink friend. There had been that hoof buzzer...the small scary pony in a spring that popped out of presents to give you a fright...the endless whoopee cushions. Okay not all of it was Twilight’s idea of fun but what was important was Pinkie was her friend and she had asked for her help, it would be bad form not to go along and give her a hoof, especially as the Princess of Friendship.
Walking through town she pondered more what it might be. Pinkie often got new party supplies in and it wasn’t so far fetched that she asked her friends to test them out from time to time. Some of them took multiple ponies to try out and she wondered if she had been the only one that had been asked. Perhaps she might find one of her other friends there as well. Last time she had asked both her and Rainbow Dash to meet her in town to test some sort of new pie flinging contraption. Pinkie had been the target but it had required two ponies to load and then fire it at her. There had been giggles all around as Pinkie had quite literally grabbed the pie from the air with her tongue and then swallowed it whole. That day had been quite successful, and fun.
When she arrived at Sugarcube Corner Pinkie was nowhere to be found, inside was just Mrs. Cake behind the counter finishing up with a couple of other ponies who had popped in to buy some of their sweet delights. None of her friends were there waiting for her as well, never mind. It seemed Twilight was the only one who had been asked to help with whatever this was.
“Hey Mrs. Cake, I’m looking for Pinkie Pie. Is she around?” Twilight asked innocently as she moved her eyes around the interior of the shop. Pinkie could often just pop out from nowhere at the mere mention of her name.
“No, no haven’t seen her around for a few hours now. She mentioned something about going to make sure everything was ready so I assume that’s why you’re here.” was all the mare said before vanishing into the back to get some more cakes to put out. Twilight was left alone at the front of house.
“Twilight!? Is that you!?” a voice came from behind her. “Oh you came! I’m so glad you got my letter!” Pinkie Pie exclaimed excitedly bouncing up and down on the spot.
“I did! But uh, you could have just come and asked.” Twilight replied.
“Pffffttt, I mean sure, but I know how official you like invitations to be!” Pinkie Pie said with her usual signature grin. Twilight just rolled her eyes and giggled.
“Okay, so what do you want help with?” she asked, watching as the mare turned herself a full one hundred and eighty degrees with a single hop of her hooves. The motion was quite impressive.
“Like I said, new party stuff! I’ve got some balloon’s that you’ll just love.” Pinkie giggled, stopping her hops to walk alongside her friend and explain what she had in store. “We’ll need to use my party cave for it!” she carried on excitedly.
“Um, isn’t the party cave back at Sugarcube Corner?” Twilight asked, Pinkie stopping dead in her tracks and her happy expression going to semi-serious for a split second as her brain worked. She did another one hundred and eighty degree bounce, heading back to the store as Twilight turned to follow. Twilight just tilted her head in amusement. Pinkie always seemed to be a lot smarter than she came across but wondered if something else had been on her mind. She lived at Sugarcube Corner, where on earth had she been bouncing off to? No matter.
“Whoops, of course it is! Silly me!” Pinkie exclaimed, leading Twilight back inside. She was met by Mrs. Cake once more who gave her a shrug as Twilight just shrugged back. The two went up to Pinkie’s room, where Pinkie leaned a hoof on the cupcake banister bottom to open up the way down. At least this time Twilight was prepared, following her friend down into the room below. Before Twilight remembered all five of them, Pinkie excluded had fallen down a very dark trap door onto a slide that led them down to the room. This time the slide was still present but Twilight made sure to stand off to the side as Pinkie revealed a much more sensible staircase. She confessed that she needed a way to get out as well and climbing back up a slide each time was hard work, even for a pony as energetic as she was. The light was on too, so Twilight decided it best to follow her friend down into a non-gloomy and well lit room taking her time to make sure she had the right hoofing going down.
It was just as Twilight remembered it, however it seemed more...organised. Perhaps Pinkie had been taking lessons from Twilight. There was certainly less of what she’d class as flotsam around the place. There was in fact just a few things laid out with the filing cabinets where Pinkie kept her files on her friends around the edge. The room itself was actually quite large now cleared out of a lot of the other things. The one thing Twilight did observe was a table that had a couple of very large, very shiny looking balloons on it. This must have been what Pinkie was talking about, but she had mentioned other things so it couldn’t have been just these.
“So what are these?” Twilight asked.
“Edible balloons!” Pinkie said back with a grin, picking one up. She clearly felt she needed to explain more when Twilight’s expression changed to confusion. “Something I thought I’d try! Well, actually, if you could try one it would be really helpful. I need to observe the effects.” Pinkie explained, hoofing over the balloon she had to Twilight who took it, turning it over in her own hooves to get a better feel of it. To her, it felt like just a regular balloon except a bit larger than the standard size that was often put up to decorate an event.
“Wait, why would anypony want to eat a balloon Pinkie? I don’t understand.” Twilight replied, she was was still turning it over to observe it. “I mean does it taste good?”
“Something like that, look there’s two! One for you and one for me, but I’d like to see you eat yours first.” Pinkie said with a giggle, coming close to Twilight and nudging her hooves up to her mouth. “It’s for science! You love science!” Pinkie carried on, trying her best to convince her friend.
“Look I’ll indulge you, but don’t try and convince me this is scientific.” Twilight replied, deciding that Pinkie’s balloons were probably mostly harmless. She knew her friend wouldn’t be asking her to do what she was about to do if they weren’t.
“You’ll need to swallow it nozzle first!” Pinkie said, watching as Twilight span the balloon around and did as her friend asked. It was a little difficult to digest but Twilight felt the balloon go down her throat and vanish inside her. For a few seconds, nothing happened which allowed the Princess to ask “Okay, now wha-” before her words were cut off by a tugging sensation in her rump. Between her cheeks, she felt the nozzle end of the balloon poke out, but no more. Immediately her face went red. Twilight had no idea this would happen.
“Ohhhh, it worked - so far!” was all Pinkie said.
“W-what do you mean it worked!? This was part of the plan?” Twilight stuttered, she could feel the nozzle still in place between her flanks. “When you said edible I thought you meant I could just eat it!”
Pinkie giggled in response. “Oh silly Twilight, you can’t eat balloons and digest them! They’re made of stuff our bellies can’t break down!”
At this point Twilight started to worry instead of being embarrassed. Her mind started to conjure up a number of different explanations as to why then, Pinkie had asked her to eat a balloon. Nothing seemed reasonable. She thought it best to just ask.
“So why did you get me to eat it then!?”
“For its magical effects!” Pinkie responded.
“Magical effects!? What sort of-” her words were cut off again, in her preoccupation at her body now harbouring a balloon inside it she hadn’t noticed Pinkie had pulled out a large nozzle from a tank that had been hidden behind a number of other things in the room. Despite the room being now mostly clean she had managed to sneak this one past Twilight. Pinkie wasted no time in attaching the end of the hose to the balloon which Twilight attempted to resist. This was getting strange enough for her, but when pinkie was determined she generally had no trouble getting what she wanted. Even attaching said nozzle to Twilight’s rear.
“Okay! So this should be fun! It’s my latest party trick, actual pony balloons! I thought who better than my good friend Twilight to test it huh?” Pinkie carried on, turning on the air flow. Immediately Twilight felt the balloon inside her start to fill. The only way she could think of it was that it was a very weird sensation, with the balloon quickly filling her insides and searching for space to expand. She could feel it pressing up against her body, immediately making the mare feel tight and stuffed as if she had eaten a huge meal. But there was something else…
The magical properties of the balloon were starting to become evident. Twilight feeling her hooves and legs noticed that her body was changing as the balloon filled her up more and more.
Firstly her whole body was changing its consistency, her hooves felt almost latexy. The same material the balloon was made from. It had a rather nice consistency too it, rubbery and soft she could feel the rest of her body changing to match it too. The more she felt the balloon inflate inside her the more this change started to affect her body all over. There was a faint glow of magic as clearly the enchanted balloon was doing its work as it filled up inside her.
Next her body started to change shape. Twilight herself at this stage was utterly speechless. She had never felt magic like this. Her hooves began to shorten and her whole body began to take on a much more round, balloon-like look as quickly she was powerless to resist the magic the item was enchanting her with.
Pinkie herself with a lusty and dopey grin on her face had put her hooves around Twilight as her fried inflated into the biggest party balloon she had ever set eyes on, giving Twilight hugs and squeezes as she stretched her hooves around her latexy exterior that was expanding with every second as the Princess filled up and changed. She couldn’t help but coo at the transformation, her blimpy friend becoming exactly what she had hoped for.
“Glad I have two of these, can’t wait to join you Twiloon…” Pinkie said with affection, making sure that she had a firm grip of Twilight as the transformation took hold of her. She had made sure to use helium too, with enough her lovely Twiloon would float up and be happily bopping against the ceiling of the party cave.
Twilight herself was just letting the magic take hold, she knew the balloon would fizzle out eventually. In fact, she could no longer feel it inside her, it must have fused with her new form as the gigantic blimped balloon pony felt the last of her transformation complete. Her face had changed the most dramatically, now part of her round and squeaky exterior her face took up most of what could be called the front of her new balloon body. Her mane covered a large portion of it that trailed down the side of her exterior towards her stubby, round inflated hooves. As Pinkie continued to hug and squeeze her, she felt her body squeak in delight finding the sensation rather wonderful. The Princess was now a rather lovely inflated balloon, with Pinkie finally deciding she had inflated enough, pulling the nozzle from the back and tying the end of Twiloon up she she retained her shape and size. Pinkie herself just grinned, letting the blushy Twiloon go as she gently floated up and nestled against the ceiling with a bop as her body squeaked, still getting used to the transformation.
She had no idea the magical balloon would work so well, she had her doubts obviously. She had been experimenting with something of the like for a while. Pinkie herself had always loved balloons for parties. They were such an easy to create thing and gave so much joy to all the ponies who attended. A party just wasn’t a party without balloons. The same could be said for a lot of things that made a party up, but there was something special about balloons that called to her. It was her cutie mark after all. So why not try to become the balloon? She wasn’t adept at magic sure, but with a little help she had managed to create something that turned any pony into the real life of the party. Perhaps it was a little unpleasant having to eat a balloon but, quickly the unpleasant feeling turned to wonder and awe as your body changed to take on the properties of what you had just eaten.
The balloons she had been toying with for this turned any pony into a reasonable size balloon, but she wondered if she could toy with larger balloon ponies. A bigger balloon for a bigger blimp perhaps? Her test today was suited to the room her and Twilight were occupying, she didn’t want to make herself or her friend so inflated that they filled the space completely or worse...popped.
For now, she had a second balloon and plenty of space to expand in. It had worked well beyond her wildest dreams, Pinkie couldn’t wait to get up there and join Twilight. She still had some hugs to give her and maybe a little more, the thought of being so round and blimpy was making her rather more than just enthusiastic.
“And now my turn, that turned out amazing.” Pinkie cooed, taking the second balloon for herself and letting it slip down her throat. Like Twilight for a moment there was nothing before Pinkie felt the end of the balloon squeak out her rear. Unlike Twilight however she was expecting it and casually trotted her way over to the tank of helium that she then hooked herself up to and turning the flow on.
“Ohhhhh, this is…” Pinkie started to say as like Twilight, she felt the balloon inside her start to quickly inflate. She easily settled into the transformation and was enjoying every second. Pinkie herself had always had a liking for balloons, so to become one was well, it was turning her face redder and redder the more she filled up with air. Above her, still floating around on the ceiling Twilight herself just watched as her friend was having the same happen to her as the magic took hold.
Like Twilight first Pinkie felt her whole body change from what she was used to, to a lovely and soft rubbery latex covering with an aura over her as it did. The balloon inside her pushed against the inner walls of the pink mare’s body, Pinkie giggling rather lustfully as she felt full as the pressure of it pushed against her insides.
Next her shape began to change too, firstly her hooves shortening as her body rounded out to more of a balloon like shape, her body inflating larger and larger as the tank pumped her with helium. She felt buoyant but she wasn’t anywhere near as large as Twilight yet. That would change soon enough, with her body rounding out and her face rounding out to match. Like her friend she felt her facial features shift so that what would be classed as the ‘front’ of the balloon was now her face. Her mane above her and her tail was the only thing to really retain its same shape, just bigger the cover the huge inflated balloon pony’s body.
The balloon inside her like Twilight’s had fused with her, making the transformation complete. With Twilight now used to her new shape and form she still had her magic, using it to remove the nozzle from Pinkie’s rear and then tying it up so that the pinkie pony balloon could gracefully float up to join her friend on the ceiling. With a gentle bop as her latexy exterior hit it, Pinkie giggled and blushed to face Twilight.
“I told you it would be fun.” Pinkie said with a grin, letting herself float close to Twilight. “Blimpy Pie and Twiloon huh? Why be at the party when you could be a part of the party itself.” she giggled, wiggling her stubby hooves a little in delight.
“T-this was not what I was expecting at all…” Twilight replied, but her blushy face told Pinkie there was a but coming.
“But?”
“But...I-I kinda like it.” Twilight confessed, it was unlike anything she had ever felt and wanted to experience more. “H-how long does the magic last?” she asked.
“Until we decide the party is over.” Pinkie said with a smile, nudging her way as close as she could to her friend. “Besides I have a little more I want to have with my Twiloon.” she cooed, giving Twilight a little smooch as she gently tried her best to hug her at the same time. “This is only just the start.” Pinkie said, feeling Twilight’s squeaky and shiny exterior with glee. “Let’s enjoy it.”
“No-nopony will see us right?” Twilight asked sheepishly, giving Pinkie a little smooch back to show her own affection.
“Of course not, just us two, but I wonder if I could convince our friends at some point. It would be a real party then…” she cooed. The two blimps floated toward each other, Twilight couldn’t help but give Pinkie another kiss. She really wanted to enjoy the party, getting close to Pinkie seemed to be the best way to do that with how she was feeling.
“Mmmm, well I’m sure we could get some more involved. I’d love a few more of our friends to experience this sort of magic. H-how did you get this to work? I’d love to know.” Twilight asked, but Pinkie for once was firm lipped about it.
“My little secret, I don’t want to go sharing this around yet until I’ve perfected it. Can you keep this our little secret for now Twilight?” Pinkie asked, casually floating herself into what could best be described as a snoot boop to her friend which made them both giggle in delight.
“My lips are sealed, but what do you mean perfect it? This feels rather perfect to me.” Twilight cooed back, going for a rub of her sides into Pinkie so she could feel her soft and stretched exterior against her friend.
“Ohhhh I have lots of plans for balloon ponies. Different shapes, sizes. I’d love to see just how big I could make somepony with really huge balloons.” Pinkie said with a smile, her explanation satisfying Twilight.”We could have Blimpy Pie, Twiloon, Rainblow Dash, Puffershy, Apple Fat and Airity.” she giggled, already coming up with their blimpy names. It made Twilight laugh back.
“You’ve been thinking about this hmmm?” Twilight asked, watching as Pinkie continued to bop against the roof of the cave.
“Of course! I’m always thinking about parties.” Pinkie Pie laughed. “But thanks for your help Twilight, I know it wasn’t exactly what you were expecting but now I know how to perfect it.”
“Glad I could help.” Twilight replied. “So how long do you want us to stay like this? How do we know when the party's over?”
“Ohhhh, that’s the best part! You just gotta think it is, and it is! You’ll go back to your normal self.” Pinkie exclaimed. Twilight although enjoying it decided that she had best get back to her usual routine and that she had spent enough time as a balloon for the day. In her thoughts her mind just went to ‘The party's over.’
Like when she swallowed the balloon nothing happened at first, however after a moment she felt herself began to shift back. This really was some very powerful magic indeed.
Firstly her head took back its rightful shape as her features realigned themselves to match what she had before. Then without thinking or doing anything to her tied up rear portion her balloon body began to deflate gently, the latexy exterior changing back to her usual pony form as her round and bloated body reverted to her normal shape. Her hooves too, no longer stubby and blimped also began to go back what she was used to.
Gently as the helium escapes her body Twilight felt herself float back down to the ground. With a soft and rather delicate touch her body hit the floor and she panted, collecting herself from the experience. It was nice to be back as her usual self but, it had been even nicer being up there and bloated like she was. It was very hard to describe the feeling. It had been different but, good different.
Pinkie did the same, as much as she was enjoying it. Her thoughts of ‘The party’s over.’ like Twilight had nothing happen for a moment but then she felt her body begin to revert. Like Twilight first her head came back to its normal shape and size, her body deflated and her hooves returned to normal. Like Twilight had but a few moments before her she hit the ground with a gentle tap, immediately bouncing and grinning that the experiment had been a success.
“Oh that was so wonderful! Thank you Twilight!” Pinkie exclaimed, giving her friend a regular but tight hug this time.
“Glad to have helped. Uhhhh, one question.” Twilight asked.
“Yeah?” Pinkie replied, pushing the helium tank back in its place as she tidied up the room.
“I can get helium but...do you have any more of those balloons?” Twilight asked with a blush, watching as Pinkie just gave her a rather coy smile and pulled a small packet out from one of the shelves.
“Here, this should keep you amused until I ask you to try something else. I’d like to try even larger balloons next time.” she said. “But it’ll be a few weeks at least until they’re ready.”
“No need to write me a letter either this time, just come by the castle.” Twilight said with a smile. “Who knows, you might find me floating around in there.” she carried on, packing the balloons away in her saddle bag making sure they were well hidden. “See you soon Pinkie.” Twilight said, leaving her friend to finish up in the room and get back to her work on more exciting party paraphernalia.
“See you soon Twiloon.” Pinkie replied with a giggle.
