Boyancy Battle (Patreon)

It had all been going on for about a month. A prank war that all started between boyfriends Colt and Fran over what was in the beginning a simple accident. The two were out shopping together when Fran tripped and on his way down , accidently shoved Colt over..he toppled and ended up kissing the nozzle of a party balloon air tank. Fran was dazed by the fall, so was unable to pull them off quickly..by the time he realized what had happened , his boyfriend looked like a parade balloon version of himself, with a big blushing frown. Unfortunately, Colt became convinced that it was a prank . They got their own back when the two went to a pool. Fran was just lounging on a pool toy when he suddenly felt air begin to gush from the jury rigged rubber ring straight up into his stomach. As Fran floated past the smugly smiling bunny boy, he declared (amongst groans and creaking skin) a prank war.

The back and forth continues over the weeks. Usually a couple days went between pranks to allow for some surprise. Fran pushed colt onto a water sprinkler causing them to fill, so Colt gave him gag gum that turned Fran into a big round blueberry. In retaliation, Fran replaced all the sodas in the house with super suds soda which caused Colt to blow up into a foam ball. In return Colt surprised Fran with a sudden and very public puff kiss before rolling him home through busy streets leaving him humiliated. This led into the last prank. Fran bought a gas potion from a totally trustworthy witch , which he gave to Colt. They drank it, causing his gut to start filling with so much gas that they uncontrollably began farting it out. In a spur of the moment act of revenge however, Colt made sure before he became an immobile ball to sit their ass on top of Fran, causing all of his toots to fill his boyfriend up just as much as he already was.

With that, neither party knew who was next, but was certain they were not going to get caught out.  Fran thought because Colt had got their own when he blew him up with farts. However, Colt didn't see it that way. He thought since he was still round at the time that it didn't count. He never got to plan his revenge on Fran and they got no chance  to tease and play with him as a big balloon. That was most of the fun of the whole war. Both sides were therefore planning their next move and both decided,  after a whole month of being on edge about when the next prank was coming,  that this was going to be the big one. The grand finale. Revenge was going to be oh so beautiful.

It was the middle of the night when Colt woke up. He needed the dead of night to plan his devious acts. Stealthily, the bunny boy snuck from the bed. Their eyes never left Fran within the bedroom. A part of him thinking how lovely he looked peacefully resting. Yet the determination, competitive drive and just the littlest bit of kinky desire drove him onwards down into the kitchen. The two of them would always enjoy breakfast together, so this would be the perfect time to strike. They would both enjoy a bowl of cereal, but they differed in that Colt had theirs with cow milk, whereas Fran used oat. Pulling out the bottle of Oat milk, Colt deviously rubbed his hands together before reaching into his back pocket for a little vial.

Over the last week, they had been scouring the internet for something that would top the humiliation and teasing factor over all that happened before. That was when he had found a little potion that would do the trick. That would finally embarrass Fran enough for Colt to be the winner of the war.  It was “the wanderers rescue.”. When it was first brewed it was made to make lost hikers become a giant signal for rescuers to find them easier. One drop would make them float above the tree like and let out loud farts as a sort of sound beacon. Colt giggled deviously to himself as he ignored the safety warning and dumped the entire vial into the milk. With one last devious little giggle he hid his tracks before snuggly tucking back into bed, almost unable to sleep with the unending anticipation of what was to come that next morning.

Sure enough, the next morning came and the two woke up to their usual routine. A morning kiss before both began to get dressed. Colt couldn't help but watch as Fran dawned his usual attire of a vibrant long sleeves orange shirt. It made Colt giggle to himself. “That bright color stretched over his huge body?  He's going to draw even more attention than I thought!” They stuffed their devious enjoyment by putting on their own, sky blue top. Careful of his long blond bunny ears as he did.  Fran on the other hand simply let loose his large , messy mop of brown hair before stretching the morning stiffness out of his back. “We got any plans for the day today?” He asked.

“Don't think so. We can see what we wanna do after breakfast though. I'm hungry.” Colt replied as they put on their pants. Fran did the same and shrugged. “Well duh. I'm not missing out on a bowl of Amye'o’s.”

They went down to breakfast. Colt watched Fran and was a little confused. He seemed entirely trusting, not expecting anything. It had taken a while for the potion to be delivered, so the usual prank interval had passed. It only made Colt smirk more deviously. The trap was not only set but Fran was walking into it oh so eagerly..it took all of Colt's willpower to hide this evil excitement. His arm simply nestled around Fran. In all this anticipation and deception, Colt didn't see that Fran had a pretty wide smile of his own.

As the two sat down, pouring out their bowls of Amye'o's. Colt watched Fran pour his milk. He was nervous for a second as he realized that the potion had given the milk a slight red tint. However the second it hit the cereal , the red dye of the strawberry flavoring completely hid the slight tint. Without looking away, Colt poured their own bowl and began to eat. Needing something to chew to hide the smirk begging to spread from ear to ear. Especially as Fran began to eat his , looking over his phone as he did. There was no added taste thankfully, so he had no idea as he swallowed mouthful after mouthful of potion infused milk.

Fran could barely finish the bowl before his stomach began to let out long, upset growls. The potions effects kicking in already, yet slowly working it's way up to full strength. He gently rubbed his stomach. Feeling it rumble under his hand he gave a somewhat concerned look to Colt. “Y…you didn't… did you?” his cheeks had a reddish tint already. Blowing up always made him feel so embarrassed. Colt let their devious smirk show , watching excitedly at his boyfriends belly waiting for the first sign of growth. The sounds of gurgling and groaning filled the room as Frans belly let out its complaints. “Oh I might have. And this time…it's going to be best…biggest…and most humiliating prank of all!” He yelled excitedly.

Fran blushed even brighter as his stomach began to puff out. Slowly filling out his top as his gut grew. He did his best to keep a straight face even as he felt his belly go from the pleasant fullness of the meal to the full blown bloated within seconds which made Fran groan. As his round belly began to make a visible curve against his top, he began to let out some other uncontrollable sounds. A loud fart escaped from his ass, A pinkish red puff of potion residue escaped from his rear as he did. Thankfully it was scentless. 5The soft pink on his cheeks turned beet red as he went from embarrassed to mortified. “N…not farting again! Oh god this was terrible last time even.”

“Hey! I was the one who actually got  bullied that time! I just made sure I wasn't the only one. You have no idea how bad it was turning into a fart balloon! Well..i guess now you will. But that's not all.” Colt told him.

The bunny boy began laughing with playful glee as he hopped out of his chair, coming over excitedly before beginning to gently rub his boyfriends gradually growing gut, feeling it tighten and bulge with every second passed.  Fran let out a little moan, partly excited partly nervous. He could do nothing but watch as a silver of pale skin revealed itself between his orange top and his black trousers. He tooted again, another puff of rosy gas entering the air. Only now does Colt’s words register. “W…

What do you mean…that's not all?”  he asked nervously.

“Oh I'm not telling you. I'll let you figure it out when it happens. You've got some blowing up to do first.” Colt teased him, gently running his hand across Frans exposed stomach. Even at this relatively small size the stretched skin was so incredibly sensitive. The fact he was enjoying on some level only made Fran feel so much more embarrassed. “s…stop!” He grumbled. Unfortunately this only encouraged Colt to tease him further..it became easier and easier to do as more and more belly became visible.

Frans belly wasn't all that was growing either. His rear and thighs began to join in on the fun, swelling up and quickly filling his pants. Thankfully, they were rather stretchy. Most of his clothes that had survived the last month of pranks had to be.  Yet he could still feel the fabric tightening as his gas-packed ass filled it out. Fran could only hope that Colt's trick would stop before his clothes ran out of stretch. Both watched as Frans body slowly started to take a comical tear drop shape. Colt deviously rubbed every part of the exposed belly skin as the crack between the clothes grew wider and inched further around Fran’s back.

The growth around his body seemed to be steady…until a sudden surge struck Fran , doubling his stomach's size, making it look like he had swallowed a giant watermelon. The poor blimp felt so overwhelmed at the sudden growth that he didn't notice a second one coming on , a rumbling bubbly  growl coming from his body.  Within a second, his butt and hips rapidly blew up. Unfortunately for the poor Fran, he hadn't yet gotten out of his chair, so the armrests firmly grabbed his newly swollen rear. Feeling how he filled the chair Fran tried to stand , but found that the seat clung to him. The fact the chair he had been freely sitting in moments before was now snuggly stuck to his ass made Fran feel even more humiliated.

“N…noo! Get this chair off of me!” He begged, feeling the wood press into him tighter and tighter as his rump kept getting puffier and puffier. Fran tried to push it off himself, but it was stuck tight. What made things worse was that his arms felt …weirdly stiff. He hadn't realized yet but his arms had begun to puff up, the air within making it hard to bend them. Colt could barely contain their laughter watching Fran try. An idea came to his head and he walked over to the other side of the room. “only if you can walk over to me.” Colt demanded. Fran knew it was nothing more than a chance to humiliate him but had no choice.  With a scowl that looked oh so cute with his rosy red cheeks, Fran began walking (or more accurately with his puffy thighs, waddling) towards his boyfriend.  His body creaked with every step, body swelling between each step. His arms began filling the sleeves of his top , making them look like two long balloons ending in meek, flappy hands.

Colter couldn't believe just how cute Fran looked fighting against his own massively swollen body.  Watching as each and every crease in Frans clothes slowly vanished as the fabric was pulled tight. His top was also pulled up revealing a full band of stretched skin. The slightest red tint was forming at his naval as the pressure grew within him. He was slowly looking more like a clown had made a balloon portrait of Fran, every limb looking round and puffy all attached to his slowly rounding torso. All creaking. All groaning..all bubbling as the potion within kept pumping more and more gas into him.

Thankfully, Fran was just about able to bounce over to Colt, who lost the last little bit of composure at the sight and began to laugh their ass off. Especially as his cheeks began puffing up, making his humiliated scowl even cuter. Colt gently cupped one cheek while staying at Frans flustered face. “I'm surprised you managed that. Shame too. I wanted to watch this chair explode off of you. But this? This was far far better. '' They told him with a teasing little smile.

“J…just hurry up! It's…so tight on me!” Fran begged.

“Oh I'll take as long as I need to Franny.” Colt replied , letting out a devious little laugh. Before he moved behind Fran, he quickly tied a small but strong string around Frans puffy wrist. He didn't even notice, his attention consumed entirely by his still  rapidly swelling body. With that done, Colt jumped happily along to Fran’s large stuck ass and began to gently tug at the chair. Creaking filled the air as the armrests fought to keep its grip on Frans' ballooned ass. It was only getting more and more firmly stuck as more gas puffed into him. Colt also had to contend with the loud and now very close farts coming from the blimp. Something about trying to squeeze him out of a chair only made the farts more frequent.

Unfortunately for Fran, Colt wasn't actually trying all that hard. A performance of effort. His smirk was ear to ear, especially when seeing the helpless little flapping hands either side of his big blimpy boyfriend. “Oh no…looks like it's stuck. Don't worry...I'm sure you'll burst through it in no time.” They assured Fran, who only blushed deeper. He tried to beg for Colt to remove it, but his own ass was determined to do it. The wood groaned and creaked as the joints tightened, although all was hidden under all the squeaking coming from Fran’s overstretched body. All the shifting gas proved to be too much for some of the more overstretched seams of her pants, causing rips to form down her hips. It exposed diamonds of pale , almost rubbery skin. Colt smirked as he pressed his finger into each one. “Woah… you are already so big you feel like a balloon. But you have soo much swelling left to do.” he teased. The feeling sent shivers though the poor boy. Fran felt so overwhelmed with embarrassment and pressure. The chair kept tightening around him until it tore apart with a sudden crack. The splintered bits of wood fell to the ground.

Yet weirdly… Fran didn’t.

For a second after the chair exploded, Fran was taken off  his feet. Yet instead of falling onto his yoga ball sized gut or beanbag ass, he just floated there for a second. He was weightless! Or at least getting close, slowly floating down to the ground. The chair had been keeping him down on the ground but now it was gone, buoyancy and gravity began fighting on which way he was to go. “Wh…what?” he asked in utter confusion.

“Surprise! You are filling with helium! You are going to be my big fat floaty balloon! I thought after you become my blimp , I’ll take you down to the city like my own personal parade. Don't worry though. When people ask what character you are meant to be , i'll make sure they know it's you Franny.” Colt taunted , their smile wide and devious. Fran blushed harder than ever before at the idea. Shown off to a whole city of people as a bloated , farting blimp. It was humiliating to just think about. He tried to shuffle away now he was no longer trapped in the chair however his arms and legs were nothing but balloons, so stiff just wiggling them was hard. Flapping around only pushed him back off the ground, leaving him suspended just a little off the ground.  Colt couldn't help himself but to jump on top of fran , knocking him back to the ground and causing another large , loud toot as he did. To them, it felt like jumping onto a big soft yoga ball. But to Fran, it was a pulse of pressure across his entire body sending shivers of pleasure across him. His whole body squeaked like a dog toy which only made his blush ever redder. His only slight saving grace was the fact that his hair fell over his eyes, stopping from watching himself get bigger. “I should blow you up more before bed. You'd make such a comfortable mattress. Shame you'll be floating around till tomorrow.” Colt teased.

“TOMORROW? I'M GOING TO BE STUCK AS A BLIMP TILL TOMORROW?” Fran asked wide eyed in surprise.

“Well… ish. It says it takes about a day to wear off . but don't worry. I'll only parade you around for most of the day. But after that, i'll just enjoy you like this as my bed.” Colt remarked casually before looking around at his swelling bed. “Speaking of… I best start getting you outside. You won't be able to fit out of the door for much longer.  Come along blimpy!” they taunted. Colt hopped off of Fran , who was fully frazzled from all that was happening. All he could do was helplessly flap his hands and kick his feet as Colt began to gently tug the string tied to him , pulling him along. They frowned however. “Hard to keep hold of this damn string. Better tie you to me. Wouldn’t want you floating away now would we ?” even this was said with such a sadistic little smile, Colt was loving every moment of Fran’s adorable embarrassment. Deep down it was clear that Fran was loving it too.

With a loud creak and small toot, the two pushed out of the double doors (which were still almost too narrow for Fran to slip through)  and stood in the open air. Wind immediately began to whisper around Fran as if eagerly chanting for what was to come next. These little wisps were all it took to jostle and shake around the overfilled balloon, almost making him dance around. The string around his wrist was all that held him securely to the ground. Colt knew as much and teasingly let the string go a little. Fran bobbed a little higher making him let out a nervous scream. Before he could get too panicked ,  Colt pulled the string tight to make sure he didn't fly too high. “Don’t worry Fran… I’d never let you float away. Just let you soar high enough so everyone can see what a blimp you are!” they taunted. It was getting harder for Fran to deny what was happening to him. Slowly , his body was becoming more round. His arms and legs were slowly merging into the same continuous curve. So much more spherical and round. Thankfully his clothing survived with only a few errant rips. The inflation was starting to slow but the tug of the sky was intense. Colt had to actively pull downwards to keep Fran from floating off to the max length of the string.  The pressure within him kept letting farts out uncontrollably. Even here, Fran was such a sight that he felt utterly humiliated. He began to get really panicked seeing the open sky. Colt noticed it and cocked their head. “What’s got you so worried?”

“W…wanderers….rescue!” he stammered out. Colt giggled at his nerves at the mention, as if he didn’t already know what potion they had got Fran with. But that was when it occurred to him.

“H…how do you know what the potion is called?” he asked nervously. That's when he felt it. A deep rumbling in the depths of their stomach. He looked down and saw that his gut was already bulging out a little. “I put…some in your milk…. I got the delayed action stuff. Thought it would be funny for it to happen while we are out and about… y…you got to get inside now!” Fran tried to warm Colt, unfortunately it was too late. They turned on the spot, and began running for the door. As he did he furiously grumbled. “No! I can't believe you got me again! This was supposed to be my grand finale! Not yours!” . Unfortunately Frans large body was near impossible to move fast with how much the air dragged against him. Not to mention, the slow release potion was so much faster than the one that Colt had used.  It only took seconds for their belly to swell out from under their top revealing their stomach to the same chilly breeze that had been taunting Fran before. The bunnyboy gasped, surprised at the ruthless speed of the gas. He immediately began tooting as he quickly started to fill all over. Legs puffing up making their desperate strides less and less effective with every second. Running became walking, which became waddling. Before he could even touch the door, Colt ended up tripping over his own swollen thighs.

Yet, he didn’t hit the floor. With his body with helium, his weight was no longer enough to keep Fran grounded.  Colt could only frustratedly flap his hands as the pair of them began to lift up. “Noo! I can’t be a helium balloon! This isn’t fair! I  was supposed to get you! It was going to be perfect! You were going to get so humiliated!” he pouted. Luckily for him, he enjoyed inflating much more than Fran. Unfortunately the bitterness of being got even with all his subtle espionage spoiled it for him. “Y….you don't get the half of it baby…” Fram stammered, having a clear view of the sky above them. “Wi..winds going to drag us over the city…” Colt thought about the words and realized the two of them were about to be a fun show for everyone. For…a whole day at least. As Colts body began rounding out and as their arms and legs thickened into conical balloons attached to his large torso, they were only able to scowl cutely. Even his ears got a little puffy, making the bunny boy look even more adorable even with his bubbling anger. The two raised up into the sky as that once gently whispering wind was now howling in delighted schadenfreude. Their home was gradually becoming a distant landmark as the sky teasingly dragged them to an audience. All Colt could do in the face of his grand finale is swell bigger and bigger with the same potion he wanted to use in the first place. His freckled cheeks slowly swelling into vision.

Two blimps, tied by the wrists. As Colt grew to match Frans size, the two of them were slowly dragged to be face to face. Both puffy , inflated blimp parodies of themselves. Despite the shame of being a pair of helpless orbs slowly creaking across the city sky, they smiled at each other. Despite all the pranks, the schemes… and the unending humiliation that was about to follow, the two loved each other so dearly.

The pair of balloon boyfriends bobbed around in the sky helplessly , farting , floating and occasionally kissing when the winds pushed them close enough to each other.
