[inflation, helium, water, popping, f/f, multiple]

Sophie stepped out of the bathroom in a two piece bikini. She wasn’t used to showing so much skin, so she couldn’t help but blush as she made her way towards the pool outside. She had been invited to her friend’s house for a pool party and had just finished changing. Sophie had been to a pool party before, but nothing could’ve prepared her for this one!

The pool area was filled with other girls her age. All of them in bathing suits. A rough count showed her that there were at least several dozen other women here. The pool was large, and there was a wooden deck nearby with lawn chairs, tables, and other assorted plastic folding chairs. It was hot out, but not burning, and there was a lovely cool breeze that made being outside quite enjoyable. Along one side of the pool area next to the fence were a couple venders of some sort. Sophie thought she saw a balloon vender dressed like a playboy bunny.

Sophie’s initial hesitation was slowly dissipating. She actually felt quite comfortable being around so many other girls. If this became a reoccurring party she certainly wouldn’t mind coming back again and again.

Sophie wandered around the pool looking for a place to sit. She spotted a series of lawn chairs in a row along the side of the pool. A couple of them were occupied by rather well endowed women, and Sophie blushed a bit from staring at these women’s enormous chests.

“First time here?” Said a voice from behind her. Sophie spun around and was greeted by a gorgeous woman with bright pink hair wearing a similar two piece bikini to her own. Sophie nodded and looked back at the chairs. She could’ve sworn that the breasts of the woman laying nearest to her had gotten larger somehow.

“Here, I’ll help you out. Follow me!” Said the pink haired girl. She led Sophie to a pair of empty lawn chairs. Sophie noticed that there was something that looked like an air hose nozzle sticking up out of the seat of the chairs. That seemed odd. Wouldn’t that feel uncomfortable?

Almost as if the girl had read her mind, the pink haired lady smiled and said “it’s okay, you sit like this on them!” She then pulled her bikini bottom down just a bit to expose her butt. Sophie watched as the pink haired girl delicately wiggled herself onto the nozzle, blushing quite red and biting her lip as she did. “See? Just like that!” She said.

Not wanting to be rude, Sophie did the same. She slipped her bikini bottom down and gingerly placed her butt over the nozzle. It was cold to the touch and sent shivers across her skin. But at the same time it slipped in like a glove and she felt no pain at all. She layed back in the chair and let out a long satisfied sigh of relief as a cooling sensation began to wash over her body.

“Don’t fall asleep!” Giggled the pink haired lady.

“Why not?” Asked Sophie. Turning her head to respond she was surprised to see that the pink haired lady’s originally small chest was looking a lot larger than it had been before. Almost like they had been plumped up somehow.

“It feels nice as you blow up, but if you stay here too long you just might-“ suddenly there was a loud BANG! nearby and a burst of confetti shrapnel fluttered in the air. Sophie looked over and the large breasted woman she had initially seen laying on a chair was nowhere to be seen, although her ripped bikini was draped haphazardly across the back of the chair.

The pink haired girl giggled. “You might end up like that! Blown to pieces!”

“That’s not possible!” Said Sophie in defiance. But then doubt entered her mind. “Is it?”

“It is if you stay seated for too long! Look at yourself!” Said the pink haired lady. Sophie looked down and was shocked at what she saw. Her breasts, which had been a decent B cup before, were now pushing out into the double D dimensions. Sophie sat up in alarm and instinctively cupped her new assets. They were cool to the touch, but not heavy. In fact they felt really pliable and soft.

“Better get up soon!” Said the pink haired girl with a bit of strain in her voice. Sophie looked over and noticed that she too had an enormous chest and it was slowly getting larger by the second. Sophie popped her butt off the plug and stood up. She could hear a faint sound of air blowing from her seat. Had she been inflated like a balloon? Is that what was happening to her new pink haired friend too?

The pink haired girl let out a low moan of pleasure and Sophie watched in surprise as she sunk further back into her chair, not caring that she could easily share the same fate as the girl who had just popped. She bit her lip again as her bikini top split open and her enormous breasts billow in the breeze free of their containment. Sophie was stunned and couldn’t stop watching the girl’s breasts growing and growing.

Then, suddenly, the pink haired lady let out a pathetic whine of pleasure before she suddenly exploded into rubbery shards with a BANG! Her ripped bikini top slapping Sophie in the face. Sophie was stunned. She looked down at where her new friend had just been, but all she saw was a pile of rubbery scraps and a nozzle blowing out a steady stream of air. The pink haired lady had burst herself!

This should have scared her, but it didn’t. For some reason watching the pink haired girl pop like an over inflated balloon sent warm tingling sensations through her body. Sophie adjusted her top which squeaked like rubber against her own enormous balloons. Maybe… maybe sometime soon she would be popped as well? Was that her destiny? To end up as a pile of useless scraps of rubber like her friend? The thoughts raced in her mind and Sophie was surprised to find that deep down she kinda secretly wanted to be popped. But for the moment she had enough sense to ignore that desire.

A short blond with pale skin and freckles effortlessly brushed away the scraps of her friend and sat down in the now vacant seat, giving little thought to the fact that a woman had just exploded before her. As Sophie turned to explore the pool party she heard the sounds of a woman moaning followed by ominous creaking and then a loud BANG! behind her.

———

Sophie was much more alert about the type of party she was at. The idea that she could be popped like a balloon at a moments notice was thrilling. She weaved her way through the crowd and noticed that a lot of the girls here were equally inflated like her. The majority of the girls here had enormous breasts, some sported enormous butts too, and a small group were completely spherical and waddling around slowly with their arms stuck pointing out to their sides.

“A little help!” Squeaked a voice to her left. Sophie looked down and saw an overly inflated round balloon girl drifting along the top of the pool’s water. She was wiggling her hands and feet helplessly as she bobbed up and down on the waves in the pool. Her distorted and stretched one piece bathing suit made her look like a giant inflated beach ball.

Sophie noticed that the poor girl was drifting towards the deep end of the pool and so she leaned over and gave the girl a bit of a push with her foot. The girl said “thank you!” In a high pitched squeak as she drifted back towards the shallow end.

Sophie couldn’t help but think that being that helpless and round looked like a lot of fun. But she also knew it was dangerous and she would be at the mercy of anyone around her. She shook off the feelings, no matter how intense and pleasurable they were, and continued wandering through the crowd.

———

There was a Ka-SPLOOSH and Sophie looked over just in time to see a dark skinned girl get splashed in the chest with a water balloon. The girl giggled at first, but then something odd happened to her. Her once rather buoyant breasts began to slouch and sag, almost as if they weren’t filled with air but with some sort of liquid instead. And that’s precisely what was happening. The water balloon splash has turned her breasts each into water balloons themselves. They jiggled and undulated as she panted for a moment as the transformation continued.

Sophie bit her lip as she watched the poor girl’s breasts overflow her bikini top. The girl bent over, as if the weight of her breasts were too much to stand up erect. Her breasts didn’t stop growing. Soon the poor dark skinned girl was laying on top of two enormous water balloon breasts. She let out moan after moan as her tits swelled up with water.

Sophie had a feeling she knew what was going to happen next. She took a few steps back and hid behind another large breasted girl as the dark skinned water balloon began to creak and groan. Suddenly there was another KA-SPLOOSH! as the girls breasts exploded in a torrent of water that spread across the hot concrete. Dark shards of rubber scraps and a torn bikini were all that were left of the poor water balloon.

The girl Sophie had hid behind giggled. “That was soooo hot, wasn’t it?” She said while turning to look at Sophie. Sophie found herself blushing as she nodded in agreement. “Hello there, cutie! My names Sun!”

“I’m… Sophie” said Sophie as she brushed the hair from her face bashfully. She was having trouble looking Sun in the face because she was so beautiful to her. Sun’s smile broadened and she cupped Sophie’s face in her hands delicately.

“Don’t worry… I’ll make sure nobody pop you but me!” She said. Sophie felt her heart skip a beat. This woman just said she was going to pop her, and yet she felt strangely reassured by her statement. Even slightly aroused. Again she found herself nodding in agreement much to her surprise.

Sun took her by the hand and the two of them wandered through the party together. Sophie leaned up against her and all fears and doubts began to fade away. Sun smelled nice, too. Like roses.

———

The two approached the balloon vender Sophie had seen before. The attendant was dressed in a skimpy playboys bunny outfit with a fluffy cotton tail and bunny ears and everything. But despite standing with a large metallic tank of some sort, she wasn’t selling balloons.

Sophie watched as a girl approached the vender. Her eyes widened as she watched the girl pull down her bikini top to expose her bare breasts to the world. The vender just smiled and placed a nozzle connected to a long hose over the girl’s right nipple. There was a loud hissing sound like air filling a balloon, and Sophie realized she wasn’t far off. She watched enraptured as the girl’s right breast began to swell up slowly until it was at least three times its original size. Then the attendant took the nozzle and placed it over the woman’s left nipple and did the same thing. After a short while the attendant removed the nozzle and bowed. The girl giggled to herself and pulled her bikini back over her breasts, although with a bit of effort as they no longer fit properly. She bounced away into the crowd with her enormous chest squeaking loudly like taut rubber.

Sophie felt Sun’s hand give her fingers a squeeze. “Doesn’t that look like fun, girl?” Said Sun with a huskiness Sophie was surprised to hear. Sophie just bit her lip and moaned quietly to herself.

Apparently not quiet enough because Sun looked at Sophie with surprise and amusement. She gave Sophie a little tug on her arm and said “come with me, cutie!” Sophie, against her better judgement, found herself being led directly to the bunny vender.

The vendor smiled and bowed. Sun asked “does this do helium?” to which the vendor nodded. “Perfect! Can you fill my cute friend up with helium, please?”

Sophie blushed and attempted to protest, but found she was instead pulling her bikini top down to expose her enormous chest to this vender woman. Without waiting a second the vendor placed the nozzle over Sophie’s nipple and she felt the cooling sensation of the helium gas flowing into her breast. Sophie’s legs buckled a bit as the pleasurable sensation washed over her, but Sun helped her keep her balance. Sophie’s eyes rolled into her head and she let out a guttural moan as the pleasure became overwhelming.

For a brief second she felt the sensation stop, but it quickly resumed through her other nipple and Sophie let out a second longer moan as her other breast swelled up with helium. As Sophie’s mind was overcome with pleasure she felt the sensations around her start to fade away. Specifically the sensation of her feet against the concrete.

When she came to, Sophie realized she couldn’t see anything over her now weather balloon sized tits in front of her. Furthermore she couldn’t feel the ground either! She felt light and floaty, and that’s probably because she was! Straining her neck she managed to look down and realized that she was floating a good 10 feet above Sun’s delighted face. Attached to her ankle was a string which Sun used to yank on, causing Sophie to let out pitiful whines of pleasure with each jerk. Sophie dangled in the air, embraced by the warmth of the sun above and the coolness of the helium inside. It was such a lovely experience and she didn’t want it to end.

Sun bowed to the vendor and happily skipped away, pulling her Sophie balloon along with her. Sophie was unable to do anything but be towed around like the balloon she had become. Her mind was hazy but she wasn’t scared. Again, she felt a strong pleasant sensation washing over her body. It felt so nice! She just wanted to be Sun’s balloon forever!

———

Sophie couldn’t see anything below her anymore, so she just enjoyed staring up into the sky and feeling peaceful. Every now and then Sun tugged on her string which caused her to undulate in the breeze. She lost track of how long she had been floating like the helium balloon she had become.

But then she felt a sudden jerk of the string and her drifting stopped. Something was going on below her, but she couldn’t see what.

“Hey, wait! I don’t wanna aaaahhh!” Came Sun’s voice. “Ooohh nooooo… please… I’m… ahhhh!”

“Sun? Sun what’s happening?” Asked Sophie, a little bit alarmed by the sounds she was hearing.

“Sophie! Ahhhh oh my god! Sophie I’m sorry! I’m ooooooooooohhh yes! YES! No! Wait! Oooooooohhh!”

Something was happening to Sun, and while it sounded incredibly pleasurable, Sophie had a fear about what that might mean for her new friend.

“Sun?” Repeated Sophie with concern.

“Ohhhh yes Yes! YES! Oh god yes! Mmmmm! I’m… oh god… I’m sorry… Sophie… but… I’m ahhhh! I’m gonna…”

BANG!

Sophie heard a loud explosion below her and she thought she could feel tattered scraps of rubber slap the underside of her breasts. Sun’s moaning and cries of pleasure had stopped.

Immediately Sophie was worried that she was about to drift away into the sky now that Sun had been popped, but to her surprise she stayed where she was dangling in the air.

A tug at her foot told her that whoever had popped Sun was now in possession of her! Sophie’s heart was racing. She could be popped at any point now! She was at the mercy of whoever had just popped Sun!

But nothing happened to her. Instead she was slowly drifted through the air to the other side of the pool. She still couldn’t see what was going on below her, but the gentle breeze helped reassure her that her time to pop wasn’t just yet.

All of a sudden she felt contact with her rubbery skin. It felt like another balloon had just bumped into her. Sophie heard a muffled squeak and a couple of moans coming from beside her. She cocked her head as best she could and saw that she was next to another inflated party guest. A red headed girl with tan skin and deep dark freckles. Their breasts collided together and Sophie let out a whine as the rubbery squeaks of their bodies reverberated through her.

There was some more tugging and suddenly Sophie felt like she was probably being tethered to something. More inflated women began to bump up against her and surround her. That’s when it dawned on her. She was part of a bundle of balloon girls!

———

Sophie clearly didn’t mind her predicament. Rubbing up against the other girls and hearing all their delicate squeaks, moans, and creaks was positively intoxicating to her. She remained up in that bundle of girls for quite some time, although every now and then one of them would be taken away. No doubt given to a party guest for their own amusement.

Sophie then began to wonder if they were being sold off, and if they were… how much would she go for? She hoped it was cheap. There was something really exciting to the idea of being treated as the helpless balloon she now was. Just a cheap sexy balloon for the picking!

Suddenly she felt a gentle tugging on her foot and felt her body drifting downwards from the pull. Someone had picked her! She feebly waived goodby to her fellow balloon girls, though she doubted any one of them was actually paying attention to her anyway. They were too wrapped up in their own bliss to notice her departure.

Sophie bobbed in the air for a bit while being pulled along and then she felt the tugging again. Gradually she was pulled down from the air and came face to face with her friend. The girl who had put on this pool party in the first place. Patricia!

“Sophie! Oh I’m so glad you’re still in one piece!” Cried Patricia, her face beaming with delight at seeing Sophie’s distorted balloony body. “How’d you end up there? Last time I saw you Sun Yung was walking you around the pool!”

“I… i think someone popped her… “ said Sophie with bated breath. Her voice was still a little high from the helium and she sounded like a chipmunk. Patricia laughed.

“Ah… poor Sun! She was such a naughty girl! It’s a shame I didn’t get to pop her myself! That would’ve been so satisfying!”

“What… what’re you going.. to do with.. me?” Asked Sophie cautiously. She had a feeling she knew the answer, but she wanted to hear it from Patricia’s own mouth.

“Well…” began Patricia in a low husky voice. “I didn’t get to pop Sun, so maybe I should pop you!”

Sophie whined.

“After all, it’s only fair, isn’t it?”

Sophie bit her lip.

“I’m gonna blow you to pieces”

Sophie let out a long moan of pleasure.

“Oh ho! Someone’s got it bad! That’s Pop Palace products for you! I’m so happy my party has been such a huge success!”

Sophie couldn’t argue. The party had been a rousing success and the constant bangs and booms of exploding girls proved it. So many of her friends and classmates reduced to scraps of rubber. Sophie didn’t envy the amount of cleaning up Patricia was going to have to do once the party ended. Assuming of course that she made to the end of the party in one piece.

Just then there was the sound of a splash and Patricia let out a surprised yelp. All of a sudden Sophie began rising into the air, freely. As her body turned she finally got a chance to see the ground below her. Patricia had let go of her string and she was flying off onto the stratosphere where she would ultimately pop from the air pressure.

The reason Patricia had let go was because someone had tossed a water balloon at her and soaked her good. And just like Sophie had seen with the dark skinned girl earlier, Patricia’s breasts began to swell up with water. In her surprise and alarm of her predicament, Patricia had let go. There was no stopping it now, Sophie would burst one way or another. But while she drifted away into the air she at least got a great view of Patricia getting a taste of her own medicine.

Patricia bent over as her breasts swelled up bigger and bigger. They were clearly heavy and they sloshed slowly back and fourth as she quivered from the pleasure. A small gathering of friends had encircled her and there was now a chant of “Pop Patricia Pop!”

Patricia let out some long moans which quickly evolved into loud orgasmic cries. The crowd drew in closer as Patricia’s weather balloon sized water filled tits undulated as they grew. Then Patrica let out one final scream of pleasure before she exploded in a torrent of water that splashed and covered all her friends surrounding her.

Sophie then watched with amusement as all of her friends who had gotten drenched from her bursting started to swell up and explode one by one too. The wet sounds of multiple KASPLOOSH! echoed in the air. Soon the pool party was quiet once more. Scraps of rubber, torn bathing suits, and evaporating puddles of water were all that were left of the partygoers.

———

Sophie let out a sigh as she drifted higher into the sky. She could feel an intense pressure surrounding her as the air grew thinner. She heard creaks emanating from her breasts as she drifted upwards and she knew that she was about to pop too.

Sophie decided to enjoy her last moments as a human being before she exploded into scraps, so she flipped her fingers between her legs and played with herself furiously.

From the ground one could hear the sounds of a distant cry of pleasure before a muffled BANG! echoed from above.
