The Biggest, The Best, simply, the GREATEST Balloon EVER!

-

One week from the event...

Trixie, the now most gracious and humble pony ever, started showing her face around ponyville again... this time truly meaning no harm, though some had indeed hadn't changed their perspective of her ever since the previous incident... s... both the ursa minor, and the dark alicorn amulet, but now she was looking for something that would pay... BIG, and something that wouldn't force her to get kicked out from ponyville for the third time.

As she walked around the town, she came across a lamppost with a "do want" advertisement... and what was in store for one who was chosen for such a job would be paid plenty for their services.

So she applied.

-

5 days before the event...

Two days later she went to the interview; it was from a family that had lived in canterlot, but happily moved here to Ponyville temporarily for a party they had reserved months ago for their son, Jacob. They had everything they needed for the party, but they needed a magician who could perform a SPECTACULAR magic trick with balloons, because their son loved them so much.

"You see..." Jacob''s mother started. "We need someone who can perform a magic trick with balloons, but not just any balloon, we need the largest balloon that can be made."

Trixie thought about this, sure she had seen some big balloons in her time, but assumed that they'd already tried this before.

"How big do you need it?" Trixie inquired before using magic to conjure a hollow magical shell, making it the size of a 16 inch balloon.

Jacob's father shook his head in sorrowful disdain. "We did that for his 4th and had luckily made it big enough for a 20 inch for his fifth birthday."

She expanded the hollow magic shelled orb, forcing more empty space into it, growing it to the size of a 36 inch, fully stretched out to a 40 inch. "This... big?" She panted.

Jacob's mother shook her head, just like her husband's. "We did that for his 6th, but he threw a horrible fit for his seventh when we tried to make it a 40 inch when we used the same balloon, but couldn't get big enough; Sadly, my husband is a bit fearful of loud explosions."

She then ruptured the massive orb as she could no longer contain the empty space when it hit 60 inches. Trixie panted trying to catch her breath as she had never used that much magic before, excluding the time when she had the alicorn amulet.

"We've tried that as well." Jacob's father interjected, "We had to use that, a 72 inch at christmas last year to make up for his birthday..." he then sighed heavily. "We're sorry... we just don't think you're cut out for the job. There was going to be plenty of money to go along with it. We would've paid you in advance too."

Trixie fell from her seat as she tried to catch her breath. She then reached out her hoof as if for a last appeal. "Wait! What if I can get you an even bigger balloon. It'll be a live performance, even!"

"What will you use then?" Jacob's mother inquired.

"Myself," Trixie said weakly. "I'll become the biggest, the BEST, THE GREATEST BALLOON EVER for your son."

Jacob's mother and father rushed to her side, soon carrying her off to the hospital.

Before Trixie passed out she heard the two most glorious words ever that she hadn't heard for the longest... "You're hired." Jacob's mother said.

-

Three days before the event.

3 days before the party Nurse (it'd be funny if her name we're purpleheart, it'd be making obscure references to a very powerful nurse who experienced a lot of things, but then again, she probably wouldn't be so nice if she were.) Redheart was beside Trixie when she awoke and said bluntly, "You have a V.I.P. waiting to see you."

Trixie nearly passed out again as she saw Twilight enter her room, not only just as herself with a crown but with wings, too, as she witnessed that she was now an alicorn.

Trixie's mouth made erratic movements but no words dared leave as she was speechless.

"Hello Trixie. How're you?" Twilight inquired as she stepped up to Trixie's bedside, concerned for her former rival in the magical arts.

Her mouth still made erratic movements as she tried to pay attention to Twilight's form as a whole, earth pony body, unicorns horn, and then at the peak... Pegasus wings. No matter how hard she tried to comprehend the fact, it became practically impossible to understand...

"T-Twilight Sparkle.... I-I-I-is an.... Al-Al-Alicorn. " Trixie stuttered and muttered incomprehensibly as she tried continued to try to make sense out of all of this.

"W-what are you doing here?" Trixie finally spat out.

"Well while I was here attending to other matters, I saw a certain somepony being dragged into E.R.. What happened?" Twilight asked compassionately.

"Well you see Twilight..." said Trixie as she motioned for the mare to come closer.

Twilight did just that, pretty much leaning her ear upon the turquoise mare's mouth.

Trixie then so vibrantly and loudly explained with a massive overflow of joy...

"I GOT A JOB!"

Twilight rubbed her ear as she nestled back in her seat slowly, after being nearly thrown out of it from Trixie's joyous occasion. "Well that's good for you." Twilight said in a mostly sardonic fashion.

"Yes... but um... Twilight..." she said as her voice lowered. "The humble and modest Trixie requires your assistance."

Twilight looked at her with a piercing inquisitive, and yet ominous gaze. "Does this have to do with your job? And if so, what do you have to do."

Trixie was all for telling Twilight the truth, but her mind was then derailed as she thought about how to form it into words. "Well..." Trixie stammered. "It requires for me to make a really big balloon. Far bigger than any massive balloon you've ever seen."

"Where do you plan to get one of these made?" Twilight inquired with concern.

"Ehe..." Trixie chuckled saccharinely. "Well you see... I happened to volunteer for myself to be the balloon."

Twilight nearly fell out as she exclaimed "WHAT?!" But managed to compose herself as she bucked her hind legs back with vigor as she was disquieted, still agitated that Trixie had willingly volunteered herself. "Tell me Trixie... how much are they paying you for this job?" She questioned with concern for her friend.

"Well... far more than a normal magician would get paid from doing a birthday party." Trixie stated. "Uh... a rough guesstimate would be approximately... to the fourth or fifth power of it...." She added in a quieted voice.

Twilight blinked her eyes repeatedly as she couldn't believe her ears. "Fourth or fifth power?"

"Yes..." Trixie replied, her voice still quiet while she continued to speak. "And... that's only the first installment."

Twilight's eye nearly started to twitch as the information was being relayed to her. "And... just how many installments are there?" She asked, now indeed concerned about what was going on with her new job.

"Well... it depends on their child's happiness, so that's why I'm asking for help that way I can become the biggest balloon ever!" Trixie exclaimed with euphoric glee, a bit too much that it seemed to carry an ulterior motive far past receiving a big payoff.

"..." Twilight said nothing, but was deeply concerned for Trixie, but decided she would help her out. "Fine Trixie, but I assume that you won't do something as irrational as burst yourself into lot's of pieces, yes?"

Trixie simply nodded and shook her head with the sincerest face possible, thinking that her voice would fail her if she were to tell Twilight the truth. Because, truthfully... she wanted to see how big she could get. And then maybe... push past those limits.

-

One Day before the event...

Trixie hummed happily as she trotted to Twilight's to practice once more in her usual getup. She couldn't believe it... she was actually being helped personally by a princess, who used to be her own personal enemy.

As she had continued to make her way to Twilight's, she bumped into an odd looking stallion who held his head down as if ashamed and had seen something that was literally petrifying him.

Trixie quickly apologized. "Oh! I'm sorry."

The stallion looked up from the ground to see her and said, "Tis alright, madame, it was my fault for not looking. For your trouble, have this." He handed her three little light blue pills, as blue as the color of her coat, and insisted that she take it for the trouble he caused her.

“What exactly... are these?” Trixie asked.

“A special pill I’ve been making,” the stallion said. “Sort of... wishing pills. Swallow and it will help you get just what you need. Not exactly what you had in mind, but they will help you how you need them if you think about your problem.”

Her mind filled with thoughts. She was having difficulties with her latest act, as it were. She could barely reach seven feet before reaching strain. While good, it could be better.

“And these are... safe?”

“Of course! I’m working on selling them now, and guaranteed money back if they don’t work. Well, you’re getting them free, so, heh. In any case, I must be on my way. I wish you luck with your endeavours!” With that, the stallion walked away to the market, still keeping his head low as if hiding.

Hoping for the best, she took one after he had trotted away and wish for the magical power to make herself grow... instead, her form was changing.

When Trixie arrived at Twilight's, she kept hearing this unbearable squishy and squeaky sound that was made every time she took a step. She didn't notice that the sound was emanating from her until she was invited inside.

When Twilight laid her eyes upon Trixie, she took a deep gasp of air in shock as she tried to utter: "Trixie! You're made of rubber!" But could only stutter "R-rub-rub-rub..."

"What?" Trixie inquired blandly as she looked at her hooves, noticing that they were indeed much clearer and more rubbery than what they used to be. "Ah! I'm rubber!"  Trixie screamed, indeed in shock of her new form.

Trixie then had a mischievous thought, calming down and smiling. "Hey, Twilight, let's go through the routine?"

Twilight stammered at the thought of doing the routine. "What?! Trixie! If you haven't noticed, you're made of rubber!"

Exactly, Trixie thought. "Then you should hold onto these for me." She trotted over to Twilight with loud, gleeful squeaks as her hooves hit the ground. She then went into her hat and pulled out the other two pills that the weird cloaked stallion had handed her.

"O-kay..." Twilight said as she took the pills from her, storing them in a small interdimensional space. "But... are you sure you want to go through the routine? Because it could be dangerous, especially now!"

Trixie had sly thoughts as she looked as her squeaky new form as she trotted around, getting a bit of an excessive view of herself.

"Mhmm..." she agreed with a hum as she looked at herself.

"As you wish." Twilight said before she began to inflate Trixie with magic, causing Trixie's form to grow and swell out.

"Faster!" Trixie moaned softly as her form started to bloat out and grow, first starting in the stomach, and then slowly moving out, taking in other parts of the body with no strain whatsoever.

Twilight had no choice but to comply, but sadly, couldn't help but worry for her friend who was growing double, and now triple the size she was before, as she poured a massive influx of magic into her.

As Trixie moaned, Twilight struggled, because like last times she was being filled with pure magic until she started to strain, but now, Twilight's magic was slowly wavering as she was being filled up with so much pure magic. "Unnnff..." Twilight groaned, now having to think of another approach to filling her up.

Twilight then withdrew most of her magic that filled her out, but still kept the outside of the sphere that was filling her up, and added upon that sphere so she could continue the job, but it seemed as if she was getting too big, without any signs of straining, groaning, or creaking whatsoever.

"Ooooh! I'm going to become the biggest!" Trixie moaned as she started to reach really close to Twilight's ceiling from her growth and filling out as her hooves now started to sink in, her size nearly taking up the first floor of the library.

With Trixie's such marvelous and massive expanse, she had no choice but to move up to the second floor as her massive and light frame started to knock things over.

When Twilight moved upstairs, Trixie's massive frame lurched in all directions, causing her to continue to grow and swell out, but so much more, as if the empty space Twilight were filling her with was an incentive to expand..

"Uh, Trixie? Don't you think you're getting a bit big?" Twilight inquired as she felt like poking the softly moaning, squeaky and plethoric Trixie. She was a bit scared to did so, thinking that it might cause her to spontaneously rupture if the magic was disturbed, but somewhat against her will and favoring her intrigued curiosity, she poked her causing Trixie to give a shrill, saccharine moan.

"OOOOooooooooaHH!"

Twilight jumped back some as she heard the moan. "Uh, Trixie? Are you enjoying this?" She inquired with great concern.

"Who says you can't have a little fun while you do your job?" Trixie replied, in the form of a question, proposing a good rebuttal against Twilight.

"Touche." Twilight, then poured a massive spike of empty magic into Trixie, causing her to moan even louder as she hit a new record in her current growth, her body also started to creak softly as she started to press against everything in Twilight's library.

"So big... but... I must get... bigger!" Trixie moaned quietly to herself,  as she continued to grow and her rubbery face began to flush with red. "Oh... let me become the biggest!" Trixie continued to moan softly. "The best!" She moaned louder. "THE GREATEST!" She yelled as euphoria came over her as her body squeaked ravenously.

"Uh, Trixie, unless you want to burst, I suggest that we stop, cause I think that euphoria is overcoming you." Twilight bluntly stated.

Trixie moaned deliriously, but heard every single word that Twilight said as she felt herself slowly shrinking. She flailed her nubs of hooves in protest as her body now deflated at a quicker and quicker pace. "No! Wait..." she protested through moans as her body returned back to her normal size and her body reverted from the rubbery state it was at back to normal, heavy hooves and all.

"Good thing we pulled back, else you might've just ended up in pieces." Twilight said in relief.

Trixie whimpered, she felt no such thing as strain upon her body, she felt no such reversal take place. "Well, tomorrow is the big day..." she said with a bit of sadness in her voice. But then a naughty thought came to mind.

"Twilight, don't forget, the party starts at 3:30, and my performance begins at 4:15." Trixie lied, knowing full well that her performance actually started at 4 sharp. "You know what, Twilight, let me have those pills back. I have to be there early so I'll be there on time for my performance."

"Fine," Twilight said placing them back into her hat.

Trixie placed it back atop her head. "Thank you princess, I hope to see you at the party tomorrow." She said with a bow and a wave, leaving Twilight's with a most lucid thought.l: I'm going to be the biggest! With a bit of arrogance; I'm going to be the best! She boasted. And she had to stick her hooves over her mouth before she yelled: I'M GOING TO BE THE GREATEST BALLOON EVER!

-

The day the dream became reality...

Trixie arrived at the party place early, just to find that she ran into the stallion she had ran into the day before was the caterer.

"Why, hello there!" Trixie said with smiles and glee to the cloaked stallion.

"Oh, uh, hello madame!" He replied, trying to reciprocate the same enthusiasm. "Uh, how've you been?"

"Oh, just wonderful with your great wishing pills!"

"Oh, so they fulfilled your wish?"

"Well...." she said straining the word out plenty, hurting the poor stallions soul the longer she held it. "To some extent."

He twitched violently. "It-Oh, uh, it didn't?" he asked, his body twitching all over.

"No... I mean, not on your part, I mean upon the part of which of the pony who was helping me. She did a good job, it's just that she didn't push me to the max." Trixie stated, hearing his discomfort.

"Ahhh, I see... I'll make sure to fix that for you madame. But here, have this!" He pulled from his bag a clear large pill. "It's sort of an added boost to the pill I already gave you. Sure to help you along further."

Trixie grinned happily as she received the item from him. "Thank you!" she said, grinning and looking greedily at the pill.

 She then went backstage to go and check out her props for her performance and saw just what she needed, a limitless air tank. She put the hose into her mouth and inflated herself just a bit, moaning gleefully as the air went into her mouth, but then had to rip the hose out from her mouth before she became too euphoric.

-a little while later-

"AND MAY WE PRESENT THE GREAT MAGICIAN TRIXIE!" The announcer said through the microphone as Trixie made her way onstage.

That's GREATEST, Trixie thought with a bellyful of arrogance, or air as it remained taut.

"Hello Children!" she greeted. "As you heard, I am The Great -est-" she scoffed underneath her breath, making it seem as if it were a slight tremble in her voice, but continued on without fault "magician Trixie. And I am here to entertain Jacob here by becoming the biggest balloon ever!"

The fairly old colts and fillies oohed and ahhed, but one little colt gave a dubious look at Trixie and gave a little scoff. “You? The biggest balloon ever? You’re not even a balloon. Besides, you could never get as big as I want you to get.”

The other little ponies rolled their eyes, and some of the adults shot Jacob some glares, but everypony else just nodded at Trixie pressed on and challenged him.

"You must be little Jacob." Trixie said with layers of saccharine in her voice, having to bite her tongue as well, hearing some not so pleasant words from his mouth. "Irregardless, I shall show you all my most amazing trick. Now I'm pretty sure you've all seen a balloon before, but I promise you all that I will become the biggest, the best, simply, The GREATEST BALLOON you have ever seen."

She then promptly stuck the hose into her mouth and turned the valve on the tank releasing a slow but steady stream of air into herself, causing her abdomen to swell and grow to quite the beachball before she took the hose out. "See children, I'm growing big just like a balloon!"

The kids were all stunned, and so were many of the grownups. Nopony had ever seen a pony grow like that before, and even knowing that it would happen it still came as a surprise.

Jacob, however, still seemed unimpressed. “Yeah, so? I have balloons in my room that can get way bigger than that. I bet you can’t even hold as much air as three of them put together!”

The others nodded, though more hoping for Trixie to continue then in agreement with the loud little colt.

"Oh really? Well then, I guess I'll have to show you my awe inspiring ability." She stuck the hose into herself and swelled and filled out with a bit of a rampant stream of air that went wild into her as she cranked the valve open again.

She stopped not long after she grew as her taut and filled stomach hit the ground, sounding a bit squeaky as she poked it, even though she hadn't taken the pills yet. "What do you think now? Am I big enough crowd or should I, the great and inflatable Trixie show you how big I can really get?"

The children all cheered and begged for more. Jacob still wasn’t acting very excited, but he raised a brow at Trixie.

“More, more!” one filly shouted.

“Wow, look at her tummy! It’s even bigger than my Momma’s!” a colt yelled, and one mare self-consciously felt herself.

“Alright, that’s kinda cool... I guess...” Jacob said.

"More you ask, and it is more you shall receive!" Trixie said, complying with the audience's wishes. She stuck the hose into her mouth and filled herself to her limit, where she was strained and filled to the brim, where every move she made caused her plethoric body to squeak and creak, causing her to go into a bit of a delirious state.

She chuckled softly and asked "Big enough little Jacob?" When she finished her sentence, a soft gale of wind escaped from her mouth, releasing some of the strenuous pressure from her.

Jacob smiled, though it still wasn’t an excited one. The other children clapped and cheered, amazed at such a massive sized pony then about her being big at all. Jacob stepped forward and felt her tight skin, giving her a gentle rub.

“This is pretty good...” Jacob said. “You’re big... for a pony. But you’re still not big enough to be a truly great balloon. I’ve seen balloon at least ten times bigger than you. What are you, eight feet around? I’ve seen balloons much bigger. You can’t get much bigger without exploding.” He stuck his tongue out at her. “Maybe you’ll do better next time.”

"Next time? Who do you think I am, some sort of regular pony? This isn't even my final form."

The cloaked stallion in the back cheered "WOO!"

Trixie the wobbled her hat from her head catching it upon her mouth, swallowing both of the blue pills and the clear pill she had received as well. "Now just give me a moment." She looked at Jacob as she said her statement, before her form changed from full and normal to clear and rubber, her form starting out as this, allowing her to get much bigger. Her form then relapsed as he abdomen fell under her and her hooves and legs came out, allowing her body to rest upon it with no strain. "Now Jacob, I'll show you how big I can really get."

She stuck the hose into her mouth and watched her form grow as she filled with air at an unevenly fast pace, about as fast as a fan on high with an unlimiter placed upon it. Her form swelled and swelled until she became close to half the size of Twilight's library.

Just then as Trixie took the hose out, Twilight walked in, but D.V.S., the cloaked stallion, stopped her at the door. "Oh hello madame. A friend of Trixie?" He inquired, his form blocking Trixie from seeing her.

Jacob’s eyes went wide, and all the ponies present stared and Trixie magically transformed into a shiny material right before their eyes. As she now effortlessly grew, Jacob’s hooves sunk into her mushy form. Against his will, he smiled, stepping back to admire her.

“Well... that’s pretty good. But I bet you can’t get bigger than my room!” he challenged, pointing at her.

"Oh I can't? Well let me show you just how big I can really get!" She forced the hose into her mouth and turned the valve so much, you could hear the air pressing into her form as she inflated. *FSSSSSSSSHHHH* Trixie was happy, she was proving somepony wrong, even if if was a colt, and was growing so massive as she did it. She couldn't believe it, she really couldn't believe it, she was now literally becoming the Biggest, the BEST, THE GREATEST BALLOON EVER! "Watch me Jacob, I'll become bigger than your whole house."

After D.V.S. interrupted the princess, he forced her to swallow an orb after she had protested with him about how that was her friend was up there and that she needed to become as big as her, even bigger possibly, if she wanted to stop her from what could be the inevitable; her end.

Twilight then dashed up to the stage and went beside Trixie as her form turned to rubber. She had to act fast, and stop her else, she would be in pieces all over the room... even though there was no sign of strain, creak, groan, or painful moan whatsoever.

Twilight began to fill out her form with empty space. She couldn't help it, but she had to coo and moan with joy as her form was being filled out.

"Now Jacob, tell me, am I bigger than your room yet?" She asked as she allowed him to take a good look at her, unaware that Twilight was beside her trying to catch up, filling herself with gallons of empty space until she matched sizes with her.

"Trixie stop!" Twilight protested.

"What! Uh-er, Twilight. What're you doing here?" She said as after she stopped the hose, making squeaking noises as she rubbed against the inflated Twilight.

Jacob looked between the two burgeoning ponies and suddenly jumped up in glee. “Oh, wow, I’m getting two giant balloons for my birthday!” He looked at them both again and hugged Trixie. “You’re definitely bigger than my room, and I want to see you both bigger! Yay, yay, yaaaaaay!”

All the other ponies cheered in amazement at the two growing ponies, and Jacob’s parents looked on in glee, more than happy to have TWO massive balloons for the price of one, as well as a show!

Jacob went up and hugged the squeaky Twilight balloon. She looked at them both again and shook in glee, resisting the urge to have his friends push them together just to hear them groan and creak together. “Bigger, bigger! Get bigger than my living room! Then my kitchen! Then my house!”

Trixie then caught up her mind as she heard the crowd cheer. "As you can see Twilight, I'm putting on a show." She said trying to acquire reprieve for her earlier fault of tricking Twilight purposely. "Besides, they're enjoying it! I mean look at the kid, even he's happy, too!"

Twilight squeaked as she was hugged by the child. "But what will happen if you explode?" She inquires, quietly.

"I won't, I promise!" She said happily, placing the hose back in her mouth, nearly breaking the valve off as she inflates herself. 'I'm going to get so big' she thought to herself as she grew and grew.

Twilight herself had to fill herself up even faster with even more empty space, trying to surpass Trixie, regardless of the consequences, she had to stop her, it was her job as a princess to do it.

As they pressed into each other the sound of them squeaking grew louder and louder as they filled themselves up, being forced to rub each other as they were impossible to move, starting to slowly take up plenty of space on the stage. Twilight slowly surpassed Trixie, but her body started to groan and creak loudly as she grew and grew.

Many of the party goers took a few steps back as the ponies they watched grew to sizes nopony could have imagined. They couldn’t look away, though, and watched in awe as the balloon ponies pushed at each other, fighting for space. Jacob only cheered, though, unable to decide which one to fawn over. FInally unable to contain himself, he gave Trixie a little kick to make her bounce a ways into the air, then did the same to Twilight.

“Yes!” Jacob screamed. “You two are amazing! You’re almost the biggest balloons I’ve ever seen! Get bigger, bigger, BIGGER!” He bounced up and down in excitement. “Look at you both, you’re almost bigger than my house! You’re nothing but blimps! Get BIGGER then blimps! And all you can do is get bigger! I want whoever wins to be my balloon forever and ever and ever!”

D.V.S. appeared behind the child and inquires. "What if neither of them win?"

As Twilight and Trixie grow, Trixie now starts sucking air out of the how seeing as she wasn't growing fast enough. MUST GET BIGGER! She thought to herself as she grew larger and larger, soon going offstage with their growth after Jacob kicked them.

Twilight protested as she tried to reason with Trixie. "You need to stop... and if you won’t listen, I’ll have to get bigger so you can see that you can’t be the biggest balloon!” She then started to inflate herself exponentially with her magic, growing far larger than what she was previously. "Trixie! You're not going to win! I'm going to be the biggest!" she said enraged, face becoming red, no longer paying attention to trying to save her friend.

Trixie glinted back at her with a vicious glare and replied "In. Your. Dreams."

Jacob turned to the pony that dared interrupt his playtime with his new balloons, listening to them make hollow thumps as they landed in the backyard’s open space. Everypony watched, almost completely frozen in place, as the two balloons became too big to fit in his house.

“What do you mean?” Jacob said with a grunt. “I’m trying to play with my new toys here, buster! Can’t you see these awesome balloons, I gotta watch them grow!”

"Can't you see here, little man, that I'm the maestro to your little symphony here?" he said in a low guttural voice. "Cause if I feel so, I can make one of your balloons peak at this very moment." He laughed through sharp teeth after he said this, morphing his hoof into a hand, ready to snap his fingers.

Twilight moaned and groaned as she bounced as her body felt tight and became covered in what felt like sweat. Which was odd because rubbery balloons don't sweat. "Ohhhhhhhh...." she moaned, feeling very, very, tight as her body was a well defined size past Trixie as she had to be left to grow and grow at the rate the tank was giving her. She tried to moan out help, but as her body somehow grew hotter and hotter, her mouth sealed from the heat and pressure.

Trixie bounced and moaned quietly. Eeee, I want to grow and grow and GROW! Someone needs to fill me up! she moaned and cried a little in her thoughts. I need to GROW! I need to become what I want to be! I want to become the greatest! Why can't anyone fill me up faster! She moaned sadly, left to flail and bounce about, her maximum size barely reached.

Jacob watched in bliss as the balloons grew massive, getting ready to be bigger than any blimp ever seen, the biggest balloons ever. His stomach dropped as his pleasure became intense, his breathing heavy. “Hey!” he said. “I don’t want them to pop because you told them to!” he whined, still watching them, seeing Twilight straining and creaking, pulsating dangerously. The partygoers were starting to feel afraid for her, wondering if she were in any trouble and trying to figure out how to help. But they were too afraid of what might happen to them if... if they were next to her when she burst.

Jacob huffed. “If she pops, I want her to pop because she got too big by herself. It should be her fault she explodes!” He laughed as if he had been told a joke, running up and feeling how close to the verge Twilight was.

"EhehehehehEhehehehehe..." D.V.S. laughed like the madman he was. "Back away... because the maestro is about to show you his final composition." He dragged the child away and pushed Twilight closer to Trixie before walking back to the child saying "Observe..."

Twilight shuddered and groaned, her lips pursed and her head shaking like a pressurized cork, her cheeks filled up. She had completely forgotten what she was doing, why she was there. Her brow was furrowed in intense concentration, frustration, anger! She had to be bigger, she had to! Her body was tight, threatening her, begging her to stop, but she refused. She needed to be bigger than Trixie, bigger than anything! Even if it meant she-

He snapped his fingers.

*TMP!*

And in the very moment the sound echoed.

*BOOOOOOOOOOOOOOOOOMMMMM!!!*

Twilight exploded right next to Trixie. But instead of Trixie flying away, the empty space flowed through and into Trixie, filling her out and making her grow and grow and GROW. Trixie spit out the hose as it she filled out without her exterior failing her, growing and expanding and filling quickly, practically doubling past the size of their house, almost filling up their backyard completely.

“I told you!” Trixie screamed to Twilight’s remains. “I told you that you could never be as great as the Great and Gigantic Trixie!”

"Now tell me, wasn't that worth it little Jacob?" he inquired, looking at him as he flicked his tongue.

Jacob was on his back, laughing and laughing and laughing as rubbery scraps of the other pony rained down around them. “She just exploded!” he yelled, twitching and kicking his legs in the air. With a grunt, he looked up at Trixie. “That was amazing! And she’s still growing! My balloon, all mine! You’re the biggest balloon ever!” He ran up to trixie and gave her form a hug. “And you’ll just keep growing and growing, just for me!” He turned to the creature, taking no notice of the other ponies hiding in fear or running away. “I wish I could see her pop again, that was great! Who are you anyway? And can you make her keep growing? I don’t want her to ever stop!”

"The thing about balloons Jacob. They always have their limits." he said patting his head. "And I'll be someone who you'll meet in the future. All I can say is..."

He snapped his fingers once more.  

Trixie moaned and squeaked as her body felt all tingly and tight, as if it were ready to collapse upon her. It got tighter and tighter as her body grew larger and larger, unable to resist as her body caved in upon itself.

"N-no! N-NO! I don't wanna burst! Not yet!" Trixie moaned and protested as her body collapsed upon itself.

D.V.S. then took his hand and moved his hand backwards as if undoing her sealed fate. "Bigger, then... MUCH BIGGER!" He grabbed the child and teleported him up to Trixie's mouth as her body let her grow and grow more as it lurched out and swelled.

"So, little Jacob. I heard you like balloons," Trixie said a bit seductively, lowering her eyelid and looking down her bloated face at the comparatively microscopic pony. "Come now, make me gigantic, I want to be big enough to crush your house." Trixie said, giggling and filly with playfulness.

Jacob grinned and hugged her huge, bulging face, rubbing her cheeks lovingly. “You... you’re the greatest balloon I’ve ever had!” He leaned in and nosed her, blushing. “I love balloons! This is really weird... I think I’m in love with a silly balloon...” With a sigh, Jacob brought his lips closer to hers. “I want you to be big, Trixie... bigger than anything that ever lived, and anything ever built! I don’t need anything else except you!” With that, he planted his lips right on hers, and began to blow her up, his years of blowing balloons paying off, not caring who or what was crushed under her bulk.

Trixie moaned with glee as she was kissed, even as a balloon, she was growing bigger and that's what she wanted. She was made happy, reaching her peak in perfection, her destiny met. She wiggled her hooves with glee and squirmed as she grew and swelled out, but she simply wanted to be bigger and bigger as she bobbed around.

Jacob rubbed her as much as he could, wanting desperately to hold all of her in his grasp. He pulled away, nuzzling her bloated jowl. “Oh, Trixie, yessss... don’t stop growing, get as big as you can!” He grabbed her head and began to pull her up and down, trying to get her to bounce, kissing her again to force more air into her.

She bounced as she bounced him up and down. "Heee..." she grinned happily. "Make me bigger Jacob. Make me gigantic!" She said as she bounced and was hugged happily. "Kiss me and blow me up." She said trying to squirm wanting more attention.

Jacob did just that, blowing and blowing, watching as his whole view filled with nothing but Trixie’s expanse. All he could see in all direction was her... his balloon... all his and nopony else’s. He blew and blew, feeling her just grow, all for him, all his own balloon, HIS! But after ten minutes of huffing and puffing, blowing her up to make it so she could use his (now crushed) house as a tiny seat, bigger than any blimp that ever was, he had to stop, using her puffy face as a pillow as he rested.

“I... can’t... blow...” He hugged her face again, huffing and puffing and covering her bulbous cheeks in kisses. “You’re mine... all I need...”

She moaned pleasurably as the only sounds her body could make was simple creaks to express her joy. And her body made plenty of creaking as she flailed around, her body under tight strain causing her to blush and reach a weird state of warmth, but her body wouldn't let her go. "Come now, Jacob. Both you and I know that party balloons are only the biggest, the best, and the greatest when they're about to explode. So please Jacob... just two more puffs?" She asked as she kindly nosed his head with her soft rubbery one. "Please?".

Jacob panted a bit longer before snuggling Trixie’s face, wedging himself into the tight crevice between her giant rounded face and her packed body, making her squeak and groan more than her hot body already was. He hugged her face, not even being able to reach halfway around her bulging cheeks. Leaning his head onto her chin, he stared dreamily into her eyes. “You’re right...” he said, almost a bit sadly. “You’re the greatest balloon I’ve ever had, but... you’ll only be your best right before you explode. You’re such a good balloon.” Jacob returned the nose rub, giving her a loving lick and a much simpler, more honest kiss. A loving rub was given to her cheeks as he did his best to enjoy her as much as he could.

He looked around at the balloon that was Trixie. He couldn’t see the ground, and could barely see the mountains in the distance. He grinned, shaking in excitement as the horizon was Trixie. Nothing but a balloon... a balloon that was all his. Still he rubbed her cheeks as he turned back to her. “Two more puffs, and then you’ll be complete, my love. But I want you to tell the world right before my second kiss... scream out and tell the world who and what you really are. Promise?”

She giggled happily and nodded, her body creaking as she rubbed her head against her body. "I will Jacob. I promise." She said, instinctively trying to hug him, but was only able to enjoy the hugs she was being given.

Jacob gently brought his lips to her puffy face and blew once more. He was pinched tighter in her fold, moaning as he blew and blew, feeling her become tighter, warm, hot, her rubbery skin changing into an angry red around her face as he struggled to hold her. Now he had no way to escape the inevitable boom, trapped between her face and her body. But he wouldn’t want to leave her in her final grandest moment.

Jacob pulled away and took a deep breath, panting as his heart raced, his body shuddering as much as hers was as his excitement built as much as the pressure in her body. “Tell me, Trixie! Tell me what you are!”

Her body squeaked and groaned as she did this, her body trembling uncontrollably as she flailed her hooves. She then yelled without a care in the world;

"I... I AM TRIXIE! THE GREATEST!"

Her body squeaked.

"I AM THE BEST!"

Her body groaned.

"I AM THE BIGGEST!

BALLOON!

EVER!!!"

Jacob laughed madly and squeezed her face.

“YES YOU ARE!!”

He then gave her one last, final, loving kiss and gave his greatest breath, making both of them shudder and groan!

She moaned her last lustful moan...

And she then exploded in a massive and loud...

*BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOM*

"Happy birthday." D.V.S. said, laughing like a madman as Trixie's pieces scattered across the land.

(AYPIHLOUGEH.)

Several days later...

Celestial kicked at a paper plate, staring out at the wreckage of the demolished home.

Luna stepped up next to her, also looking around the mess. “Amazing, isn’t it? All this destruction, caused by a single pony.”

“No...” Celestia said. “A single pony, and one balloon.” She sighed and watched as the scavengers carefully combed the garbage.

“Hmm, yes... always a shame when a pony succumbs to the temptation of growth.”

“Indeed,” Celestia said. “I still remember when ponies first inflated themselves. Giant balloons and explosions far and wide.”

“None ever got as grand as that blue pony, did they? Still...”

“Still, we’ve lost a good pony. I never thought Twilight would succumb to inflation madness. But I suppose nopony can resist the desire to be so large and great.”

Luna ‘hmm’ed and rubbed her chin. Just as she was about to speak, though one scavenger came up to them and bowed.

“Princesses, we have nothing to report.”

Celestia raised a brow. “Then why are you here? SHouldn’t you be looking for scraps of the popped ponies and the missing boy?”

“That’s the nothing, ma’am. There’s no bits of the described ponies anywhere. It’s as if they disintegrated into tinier bits then we thought.”

The princesses blinked and looked at each other. Then, a shadow was cast over them. Something was falling on top of them. They looked up to see a giant purple balloon falling onto them. Celestia gasped and magically grabbed the balloon and lowered it, confirming her fears.

“Oh, Twilight... you’ve become nothing more than a balloon...”

Princess Twilight was kicking and squirming her hoof nubs, her face red and stuffed, brow furrowed. She was moaning and groaning angrily, her horn glowing as she struggled to fill herself with more magic, despite being stuffed to the brim, her skin shiny and pulsing.

“What is wrong with her?” the pony asked.

“He mind has been filled with euphoria and power,” Luna said, rubbing Twilight’s taught flesh. “She wants to be big as possible. But after seeing a pony that can get bigger then her, her mind can only think of being bigger then Trixie. But...”

“But that doesn’t explain why she’s no longer in shreds. Somepony had to...” She didn’t finish her sentence, though, her jaw dropping and her eyes widening. Luna looked to where her sister was looking and all time seemed to have frozen.

Off in the distance, near some mountains, was a giant blue balloon. And if they looked carefully... they could still see it growing.

“You’re my balloon! The biggest balloon ever! All mine, mine, mine!”

“I am the GREATEST!

The BEST!

The BIGGEST

BALLOON

EVER!!!”

And another explosion shook the land.
