Trade in party for your ex.

Let me share RP along the idea of this thread. It is a collaboration of OtonashiAkihisa and me. Posting with his agreement.

At the gates two guards checked you and wished good luck. Indoors was a large hall with lots of people, dancing, drinking and partying. Everything was as usual, but then a projector highlighted you two and female voice greeted you: “Ladies and gentlemen, let's congratulate special guests of our show tonight.” People turned to you with interest and exchanged some murmurs.

Arielle was genuinely surprised: “Oh, are we special guests? Did you arrange it somehow? That’s quite unusual for you!”

I look over at her and smile. “Oh, um...yeah! This was all a surprise just for you, Arielle!” I look around at the groups of people and smile knowingly, walking up with her.

You and Arielle were approached by a tall leggy blonde, she presented herself : “I'm Melissa, the host of this show, I’m glad to see you two. First of all, what are your names, tell a little about yourselves. “ - she was talking leading you to the podium.

“Oh, my name is Arielle and that guy thinks he's my boyfriend, his name is JB.” - she giggled at her own joke. “Oh, very interesting. So I assume that’s you, who arranged this night out?” - Melissa winked to Arielle knowingly.

“No, this time it was JB, credit goes to him” - said brunette.

Melissa was slightly surprised but caught up quickly. “Then, okay, JB, have you prepared something special tonight besides the standard options?” - she waved her hand showing the little table in the center of the stage. There were two tanks with pressured gas under the table, a plastic hose, a handpump and two glasses with some sparkling cocktail.

I smirked and patted my pocket. “Well, I was thinking of using one of the standard options with a little addition of my own.” I laughed and walked to the center of the stage and motioned for Arielle to follow me.

Arielle was totally confused and went after you silently, trying to figure what kind of mess you dragged her into. Still she tried to maintain confident air.

I looked around at the group of people and smiled, and picked up one of the sparkling cocktails, handing it to Arielle. “I DID promise you there’d be drinking.” I said with a wink.

“What it is? Champagne?” - Arielle looked at the glass skeptically. I like champagne but this one smells odd. She waved to the jury of girls watching the show. And while everyone's attention was slightly distracted, including you, smiling to Melissa, Arielle swapped the glasses.

“Well, that’s because it’s...stronger, than most alcohol.” I looked over at her and grinned. “And I know how you like to drink, so I thought you could have both glasses!”

“Nah, that would be rude. Do you think I’m here for booze?” - Arielle sipped from her glass and added, - “For the fun!”

“Oh, it’ll be fun, all right…” I grin as I pull out a pack of special extra strength mentos in liquid form, but some of it seems to be missing already...

Melissa distracted Arielle for a second, presenting the jury to her. She explained that the competition is about the best couple, this kept brunette busy for a while and her glass was out of her sight.

I quickly poured my drink into her glass and poured the liquid mentos into it as well. I picked up my now empty glass and pretended as though I had just finished it.

“Who said I'm that eager to drink. Now what? Am I supposed to drink alone? “ She did another sip. “Strange. Last time it didn't taste like mint. Now it tastes much better!“ Arielle gulped her glass.

I laughed and looked at her, and then into the audience. “Yes, i’m sure it tastes good.” I peeled the label off of the liquid mentos and took it out. “Want some more mint flavoring?” I said and waved it in front of her.

One of the jury girls showed you thumbs up. Arielle felt her tummy with worried look: “It was strange, tasty but now I feel a little bit full.” Her black blouse was pushed outwards by her belly overflowing the belt of her jeans. “Don't you feel it too? JB? Or is only me? What was in that glass?” Her butt started to swell stretching her jeans and forming tight globes. Her blouse was pulled upwards exposing some of her skin on her sides and her rounding belly. Arielle looked down at her chest, which started to rise upwards out of her bra emitting hollow hissing sound. “What's happening to me!” - she yelled, splashed her hands.

“What’s happening is you’re blowing up like a balloon!” I said with a laugh and walked over to her, giving her newly formed love handles a pinch. “Because of this!” I hold up the liquid mentos and poured the rest of the contents into her mouth.

“No way!” - she protested. - “You can't do it to me! Stop now, or else... You may consider yourself my ex if you don't stop this silly joke right now.“ Arielle’s belt was now strained by her ballooning gut, and overstretched jeans started to rip in the seams. Her breasts were now extending past grapefruit size and looked comically like two balloons stuffed into her blouse.

I shook up her belly, disturbing the fizzy contents, and laughed. “That’s funny, because I ALREADY consider you my ex! That’s why I brought you here to get blown up like a big fat balloon!!” I backed up and watched her swell and bloat up further.

“No. This can't be happening to me! I swapped the drinks it is you, who should be blowing up! “ - she clenched her fists - “How much I want you to blow up and burst, you, jerk!” - Arielle was mad, but totally helpless as her arms and legs started to fatten with gas. Crowd was entranced by the heat of emotions. “Yeah, pop that bitch!” - cried some girl. Arielle tried to waddle but she couldn't move being overinflated that much. Her jeans torn apart and fell to the floor revealing her juicy bottom balloons. Her belly expanded, popping off the buttons of her black blouse, on of the flying buttons hit your forehead, which made her grin for a moment of vengeance.

“Gah!” I rubbed my forehead and walked up to her, going to her belt and tightening it as much as I could, grinning sinisterly at her, before pushing her onto her back.

“What are you doing, JB? please... let me deflate. “ She fell on her bottom and bounced from the floor, her midsection was constrained by her belt, causing some pain. Because of this she looked like a comic hourglass woman, with big round bottom, cantaloupe boobs overflowing her bra and her midsection relatively thin due to belt.

I walked up to her and patted her swollen breast. “Deflate? Oh, no. I brought you here specifically to burst! In front of all these people that would just love to see it too!” I looked to the audience and gave a thumbs up.

The jury seemed to be a little bored. They probably saw it many times. Arielle tried to wrestle with you, she grabbed you by the hand pulled her up closer to your face. Probably you underestimated her, as she had that missing bottle of liquid menthos in her other hand, she squeezed the plastic bottle into your mouth with all the strength remaining in her inflated hands. It wasn't that much of liquid there, but a few drops found their way into your throat. “Ha, then I'll take you with me!”

“Gah! What..?” I backed up and wiped my mouth of, before I heard a gurgling in my stomach. “Oh no…” I mumbled as my own stomach began to swell over my belt, straining my shirt and pants. “Y-you bitch..!” I cried out.

“She laughed maniacally, jiggling her fat legs in the air. Then her bra popped, letting her huge breasts out. With only panties on, she bounced on the floor a few times and then started to slowly float upwards!

“Haha!” I laughed, pointing at her with one hand and rubbing my swelling stomach with the other. The bottom two buttons on my shirt had blown off and my belt and pants button were holding on for dear life.

“No, no, I don't want to fly away! “ -yelled she, wiggling her arms and legs helplessly. Her belt finally snapped and her belly immediately assumed round shape quickly expanding into four feet wide sphere. Without extra weight from the belt she drifted upwards even faster until she hit the ceiling with her huge butt. Jury was apparently amused by your misadventures, they waved their hands and took photos with their smartphones.

I looked up at her and smiled with gritted teeth as another button shot off of my shirt and my belt and pants button shot off, sending my gut surging forward and making me look like I had swallowed an overinflated basketball. Just then, the growth stopped, as I had only ingested a couple of drops. “JB, I fucking hate you!” - she screamed as her hands and legs were gradually sucked into her growing orb of a body, her skin started to emit uneasy squeaking of overstretched rubber. Each her breast exceeded size of beachball and continued to grow. - “No, I don't want to pop, it is you who should burst!” - but that words were of no use, as she closed to the verge of bursting and people in jury knowingly covered their ears. “Well Arielle, at least you went out with a bang!” I laughed and covered my ears, but continued to stare intently at her body as it teetered on the edge. “No, no, I don't wana”... Kaboom... after thundering explosion there was no more Arielle balloon, and lots of tiny rubbery shreds and tatters in the air falling on the floor. Her black thongs fell directly at you. Jury applauded, after some talking another leggy and busty blonde came up to the stage. “Hello, JB. I'm your award, as it seems you did a good show. I like when they inflate against their will. Do you want me to be your girlfriend? By the way, my name is Michelle.“ “H-hi, Michelle! Sure, you can be my girlfriend now!” I laughed, taking a bow info front of the audience and taking Michelle’s hand to leave. “Thats nice. So as I'm now officially your girlfriend, I can take you to the trade in show.” Saying this she took a purple bottle out of her purse and sprayed you with some liquid, which immediately soaked your nude inflated belly. A hissing sound emanating from you followed shortly after. “Gah! W-what did you..?” I said before suddenly my belly began to grow further, popping off more buttons and forcing my zipper down as my pants and shirt became tighter and tighter on my swelling body. “I'm inflating you, silly.” - she smiled wide with her full lips and poked her finger into your swollen chest. She had long nails... uncomfortably long and sharp. “I wonder, can you exceed in size your poor Arielle? “ As she admired your growing body, she carelessly let the spray bottle slip out of her hands and fall on the floor. With one hand she fondled her ample bosom, while other teased you - traversing from your round stomach to your shoulder and back. “B-but..!” Was all I could manage as all of the buttons burst off of my shirt, my arms and legs began to fill up as well, slowly ripping my shirt and pants. My body shivered every time she touched it. “Relax, honey. Don't fight it, enjoy your short life as my balloon boy.” - cooed Michelle I attempted to waddle away as my legs swelled up, but only succeeding in falling forward onto my rounded belly, my shirt and pants ripping off as my arms and legs slowly became engulfed by my growing body. As you fall on the floor near her, you see the bottle with the purple spray so close, next to your face. She put her shoe with a high heel on your inflated rear. She didn't really put any pressure, just teasing you with her high heels. She doesn't care about you pathetic struggle and ignores the potential danger, but your hands are so swollen, can you reach that thing? It's your last chance. I struggled with all my might, and only managed to poke it, but I kept my finger down as the bottle emptied all of it’s contents onto her chest and stomach. (I have no idea how could you spray her boobs and stomach from below, I could imagine spraying her ass and hips from below her skirt. But okay) (I guess I was imagining it squirts more like a water gun?) It was her time to be surprised, Michelle yelled: “How dare you? I'm not girl for inflation, I'm a judge from jury!” “Oh no, stop it” - this was said to her rapidly ballooning belly and boobs. Her blouse was ruined in mere seconds, her breasts swollen as watermelons closed her sight and she couldn't see anything in front of her. She tried to kick you in desperation but missed your vulnerable belly and slipped, falling on her back. Her rear was quite inflated rising her skirt up, she bounced on the floor revealing her hips and ass cheeks pressed against each other constrained within her skirt. “No, no, this wasn't in the scenario! Guests are supposed to pop, not me!” - she wailed, but her voice got muffled as her breast pressed into her face like two car airbags. “S-serves you right!” I shouted as I became completely spherical, beginning to reach the size of Arielle before she popped. “You spend so much time watching people burst, let’s see how you fare yourself!” Michelle got so much spray, which caused her to inflate rapidly. Her skirt blew apart, top followed quickly and so she was bare chested, then, like Arielle, she started to get buoyancy and float upwards, as her legs and arms were sucked into her huge body. She stopped complaining and just waited for her doom. Jury girls had fun and put bets on who’s going to explode first. Obviously they felt no regrets about Michelle, who was one of them and now she was merely another balloon to pop. I began to float as well, looking up at her and grinning, having briefly forgotten my own situation. It quickly came back to me, however, and I began to flap my hands and feet. “Oh shit!” I wobbled in the air a bit and tried to reach for something to stop me from getting too high up. Michelle started to squeak and emit sounds of strained rubber, her huge body consisted now of a globe of belly, matching orbs of breasts and of course huge ass. She reached ceiling and watched down at you, as her head wasn’t completely engulfed by her body yet. You could see her body getting translucent... When you almost reached her, she said “Oh yes, finally!” And then BOOM. Her explosion and tatters of her rubbery skin hitting your body threw you away in direction of jury girls. “Woah!” I spun around in the air above them, close enough for them to touch as my body began to creak and groan. “Oh...h-hey, ladies…” I chuckled nervously. Then Melissa stood up and said “It was the best trade in show ever. Shame you are inflated beyond point of no return... You could be one of us, instead of Michelle. Now, do you want to pop for us, balloon boy? “ She caught you gently by the stub of your hand still protruding from your body. My cheeks puffed up and my body seemed to reach it’s limit. “I guess I have no cho-” I began to say before BANG! I popped over the jury, showering them with the scraps of my skin. Everyone applauded.
