Planet of the Hyper Farter

Bill scrolled through the feed on his phone absentmindedly. He looked up at the screen on the seatback in front of him and tapped the button to show how much longer until touchdown. Only 30 minutes left in the flight! Bill’s heart leapt as he realized there was less than half an hour until the ship touched down on Ambrosia. He slid the blind on his window up and took a peek outside.

Stars flew past in a blur of otherworldly colors as the spaceliner blitzed through space at warp speed. He quickly closed the blind again and rubbed his eyes. It wasn’t a good idea to stare into warp space for very long. Bill opened his phone back up and scrolled to his favorite community on the web, and the reason he was making such a long trip to an outer world, HyperFarts.

He clicked on a new clip on the front page. A woman with a bus sized ass smiled at the camera and then blasted a fart so loud that every car alarm in whatever city she was in started going off. She giggled and ended the recording. Bill scrolled through a few more posts, most were like the first: videos featuring women with absolutely monstrous asses blasting gas loud and strong enough to shake the earth. He opened his DM’s and rechecked his latest message.

Can’t wait to see you! Hope the trip is worth it! ;)
-Amber

Amber had been a regular poster on HyperFarts until somewhat recently. She had been Bill’s favorite poster on the forum, her thundering farts always got him rock hard. He had actually started messaging her after getting over his nerves and she had surprisingly responded. They started talking regularly with Amber always letting Bill know when she was going to post a new video and giving him early access. She stopped posting new videos a few months back and Bill had messaged her to ask why. To his surprise, she didn’t give an answer but instead invited him to come see for himself.

There was a slight jolt as the ship came out of warp. Bill rolled up the blind again and took in the view of the planet down below.

“We are now entering orbit around Ambrosia, please remain in your seats until the ship has docked with the station.”

Humanity had advanced at a meteoric rate in the late 21st century and had colonized the Milky Way. Once habitable planets were a dime a dozen thanks to terraforming, scientists had turned to other pursuits. The main one being advanced body modification. Now that limited space on earth wasn’t an issue, size modifications in particular became incredibly popular. There were entire planets full of women with building sized breasts or bigger and most men had foot long cocks at least. Other, more niche fetishes became possible as well thanks to advancements in medicine and augmentation. Bill knew of at least one planet that was inhabited almost exclusively by a few continent sized fat women that spent their days gorging on enough food to feed a country daily. And then, of course, there was farting.

Farting had always been niche and it still mostly was, however, women that had been into ripping ass could now expand their butts to monumental sizes and enhance their gas to previously unheard of levels. Hyper farting had become the new norm for those with a fart fetish and Bill was loving every second of it. His eproctophiliac ancestors had to get off by watching videos of women farting a few times and barely gassing out a room if that. Bill had the luxury of watching videos of women with asses ranging from bus to building size blasting farts that could level cities. So, here he was, riding a shuttle down to the surface of a planet on the edge of the galaxy to meet one of the best hyper farters he had ever seen.

Bill glanced out the window of the shuttle and did a double take as he saw two massive mountains dominating the horizon. They were strangely pale and round, he thought. The shuttle landed and Bill walked out of the terminal, following the directions Amber had sent him. He hopped on a bus that made its way through winding streets and up hills as it drove him closer to the mountains. Ambrosia was a relatively sparsely populated planet, most of the surface was covered in farmlands and small, out of the way towns and villages. The city around the spaceport was the largest on the planet and, as the bus made its way further out, the buildings became smaller and less densely packed.

The mountains loomed higher in the window and as Bill looked at them, he confirmed his suspicions, these mountains were definitely a woman’s enormously oversized ass cheeks. Bill was surprised as, though mountain sized asses were fairly common all things considered nowadays, you still usually heard about them and the women they were attached to in travel guides and things like that when looking up a planet. There had been no mention of an ass mountain in any of the Ambrosia travel guides he had looked up. The bus pulled up to a stop just near the base of one of the towering ass cheeks, it was Bill’s stop.

He hopped off the bus and began walking down a street, paying close attention to street signs as he followed Amber’s directions. A few more short minutes of walking and he arrived at the address he had been given. Bill could see that the house was actually pressing against the wall of ass that towered above everything and wondered why Amber hadn’t moved yet. He saw that she had a doorbell camera and pressed the button. He heard the door unlock and a voice came through the speaker.

“Door’s unlocked! Come in!”

Bill opened the door and stepped through. What he saw next caused him to drop his bag and his jaw. There was no back wall to the house, instead the pale wall of ass flesh filled the space. In the center, attached to the mountainous ass cheeks that dominated the skyline, was none other than Amber.

She laughed at Bill’s reaction and smiled.

“Welcome to Ambrosia! Hopefully the flight wasn’t too bad.”

Bill recovered from his shock and approached Amber.

“H-how?! I mean, I know technically how but I’ve never heard of anyone growing this big so quickly! Your last video was posted three months ago and your butt was only the size of a car!”

Amber laughed again and pointed at a couch that was next to her.

“Come in and have a seat and I’ll tell you!”

Bill acquiesced and took a seat on the couch, still staring in awe at Amber’s wall of ass. Amber ran a hand across the minute amount of booty meat that she could reach and looked up at her ass cleavage as it extended far above her head.

“Like you said, three months ago my butt was only about the size of a car. Everybody obviously knew that I had to have taken some ass expansion pills to grow it that large to begin with, as well as the permanent gas enhancer to power up my farts. What I didn’t tell anyone was that it only took a single butt booster pill to make my ass grow that big.”

Bill sat back in surprise, “I thought even the high dose pills took at least five to grow someone’s ass that big!?”

Amber nodded, “Yep, they only send 10 in a bottle and it usually takes the whole bottle to get somewhere around house sized.” She patted her immense ass cheeks fondly. “The doctor said my body takes exceptionally well to enhancement pills and other similar products. She also said that if I wanted to remain mobile that I should probably avoid taking any more since she couldn’t predict how my body would react to it. So this whole time that I was making hyper fart content, I had only ever taken one enhancement pill.”

Bill stared in awe again at her wall of ass. “But how did you get this big?”

Amber blushed and rubbed her thick thighs together. “Well… let’s just say one night a few months ago I was in a particularly horny mood. I had just finished recording that one video, you remember, the one where I farted so hard that I noticeably changed the air quality of the entire town? Being able to do that turned me on so fucking much.”

Amber’s hand began slowly making it's way towards her crotch. It was at this point that Bill finally noticed that she wasn’t wearing any underwear. Of course nothing would fit her but he hadn’t even noticed, being so distracted by her mountainous ass.

Amber continued, “I had gotten quite drunk in celebration of my feat and was watching one of my favorite Mandy MonsterAss vids. Not sure if you’ve seen her stuff but it’s really very hot. Anyway, her ass is like, three stories tall or something and her farts are legendary. I was going to town on myself and thinking back to when I had grown my butt and how good it had felt. I remembered that I still had the remaining nine pills from when I had bought the Butt Booster bottle back then. I looked at her ass wobble and quake and was just so consumed with desire that, in my overly horny and drunken state, I grabbed the pill bottle and downed the whole thing in one go!”

Amber sighed and began to slowly rub her clit. “My ass grew and grew and grew. It felt so fucking good, I just couldn’t stop cumming over and over and over-”

She snapped out of her reverie and pulled her hand away. Her blushing grew more intense as she looked at Bill.

“Sorry. Let’s be honest though, you’ve seen me do that plenty of times before.”

Bill chuckled, “Never in person.”

Amber giggled. “Fair. So that’s how my ass grew to the size of a literal mountain. The planetary government agreed to keep my ass out of the news and travel blogs to maintain my way of living. This planet’s pretty sparsely populated and I guess I’m pretty well liked here.”

Bill nodded, deep in thought. “That explains your titanic new booty but not why you stopped making hyper farting content. You’d be a next level hyper farter at this size!” he said excitedly.

Amber sighed wistfully, “I can’t. At this size my farts would cause untold devastation. A single toot could crack the earth and cause irreparable change to the atmosphere itself.”

Bill noticed her breathing quicken slightly and her cheeks redden even more. The idea of causing such devastation with just her farts was turning her on immensely.

“You like farting though, right? Making videos of your unstoppable gas?”

Amber’s eyes welled up. “More than anything! Blasting gas and having a giant ass are literally the two greatest things! I love ripping catastrophic farts so fucking much! Trust me Bill, this hurts me the most out of anyone!”

Bill thought for a moment before responding. “We’ve known each other for a while now, right? This may be the first time we’ve met in person but we’ve been talking for years at this point.” Amber nodded. “There’s a reason why you invited me here out of all your other fans.”

Amber nodded again, “I mean, I’m not actually all that popular out of all the hyper farters out there. Mandy MonsterAss has twenty times the subscribers I have. A good chunk of people unsubscribed the moment I stopped posting daily updates too. They liked my farts but didn't really care about me.” She wiped away a tear. “You’re different. I could tell from our conversations that, of course you loved my farts, but you loved the fact that it was me farting even more.”

Bill nodded emphatically. “I do. Honestly, I would even say I love you. I was definitely too scared to say that before but I get the feeling you feel the same way.”

Amber smiled happily and nodded.

Bill continued, “I also think you asked me to come here for another reason.” He stood up and walked close to Amber. “I think you want to keep farting. You might have grown this big in a spur of the moment decision but it wasn’t entirely an accident. You like being this big and you’re desperate to know what it feels like to blast ass like never before.”

Amber gasped and bit her lip as Bill continued. “You’re trying to convince yourself that it’s irresponsible to keep farting at this size but you really wanted me to convince you otherwise. You said you’re well liked here, the government officials all know you and what you do. They kept your mountainous ass off the books to keep tourists from flocking here so you could keep doing your thing. Think about it, has anyone actually come and told you that you needed to never fart again?”

Amber let out a soft sigh and moved her hand toward her crotch once more. Bill placed a hand on the wall of ass in front of him. “You said yourself that you love having a monstrous ass and gas more than anything. You’ve probably been holding all that gas back for three months now haven’t you? This was never going to be able to last forever with how gassy you are.”

Amber moaned and rubbed her clit harder, Bill could hear how wet her pussy was. He moved his hand to her chubby tummy. “You’ve been stuck here, unable to move for three months now. If you hated it, there were ways to shrink back down. You could’ve shrunk this ass and gone back to being regular farting Amber. The fact that you didn’t tells me everything. You love this size and you want to stay big, maybe even get bigger. You sat here and spent your days eating and getting fat because you love it!” He squeezed her tummy. “I can practically feel your gas rumbling in here, desperate for release!”

Amber moaned much louder and inserted several fingers into her sopping pussy. “Oh fuck, Bill!”

Bill grinned. “You need release and you wanted me to be here for it. I know you well enough to know how you think. You want to turn this planet into a gas giant! Ambrosia? It’s practically named after you already! You own this world, it’s time to make it official!”

Amber screamed in orgasmic bliss as her pussy gushed around her fingers. Her mountainous ass rumbled loudly and the ground began to shake. Amber let out a cackle as her breathing calmed.

“I’m so tired of holding all this back!” The rumbling grew louder. She grabbed Bill by the collar and pulled him into a deep kiss. Her tongue mashed his around as she let her true feelings out. She pushed him away as the rumbling grew even louder. Amber licked her lips as she eyed the large bulge in Bill’s pants. “I’m gonna fart like never before and you’re gonna fuck me the whole time!”

Bill couldn’t get his pants off fast enough. His cock bounced free, growing longer and thicker. Amber’s eyes grew wide as she watched it grow. “Ohhh, you’ve had some enhancements yourself haven’t you?”

Bill grunted as he grabbed his throbbing cock and lined it up with Amber’s fat, slavering pussy. “Of course, now let it all out for me!” Amber shrieked in pleasure as a foot of cock stretched her out. The walls shook and the ground quaked as her ass finally roared to life.

The fart that Amber unleashed was the biggest that either of them had ever witnessed. Bill slammed his cock into Amber’s constantly gushing pussy as she orgasmed over and over. He could barely hear anything over the thundering roar of her never ending ass blast except her moans and encouragements.

“Fuck yeah!! C’mon baby, fuck that fat pussy!! Make me cum again!! Make me fart harder!!!! Yes! Yes!! YYESSSSS!!!”

Amber’s fart grew louder as her arousal increased even more. Her house began to crumble around them as her fart raged on. Amber’s whole body vibrated from the force of her gas, adding even more stimulation to both their nether regions. Bill could see a greenish haze through the widening cracks in the wall as Amber polluted the air with her personal butt perfume.

He leaned in closer to whisper in Amber’s ear. “Is that all you got? I’ve seen what it’s like when you really try to let everything out. This is just foreplay for you isn’t it?”

Amber shrieked in ecstasy as another orgasm rocked her body. She laughed loudly and leaned back into her pillowy ass cleavage.

“I haven’t even really started farting yet. It’s time to get serious, baby!”

Bill felt Amber’s belly suck in a bit as her abdomen tightened. Her face was scrunched up in a mix of concentration and absolute bliss. The thundering roar grew even more deafening as her fart doubled in power in an instant. The remains of Amber’s house were obliterated in a second as her bassy gas blast flooded the atmosphere. Bill looked up as the roof of the house disintegrated and saw the sky above turning an even deeper shade of green. He rammed this dick into Amber even harder as they witnessed the devastation a single, unending fart was causing.

Amber pulled Bill close and moaned louder. “Ooohhhhh fuuuckk, baby!! I feel it!! Something’s happening! I’m groowwiiinggg!!!!”

Amber’s mountainous cheeks wobbled relentlessly and, much to Bill’s surprise, began growing even bigger! He stared as, far above their heads, the swells of Amber’s city crushing ass cheeks began stretching higher. The ground quaked even more violently as several million tons of ass fat grew even heavier. Bill thrust into her with reckless abandon, unloading his first orgasm deep into her pussy. Several body enhancements of his own meant that he could keep up with a goddess like Amber and (almost) match her orgasm for orgasm. Amber was ascending to such high levels of inhuman, fart fueled pleasure, however, that she was cumming almost nonstop at this point.

The gas spewing from between her obese, towering cheeks grew thicker and thicker as Amber’s ass spread to cover more and more of the surrounding land. Her cheeks climbed higher above the clouds and her gas began flooding into the outer reaches of the planet’s atmosphere. The ground crumbled beneath them as Amber’s ass sunk into the planet’s crust. Bill held on for dear life, never stopping his jackhammering for a second, as Amber’s explosive ass blasts reached a new scale.

Her ass was now clearly visible from space. Massive enough to be an entire country in it's own right, it defied belief. Toxic looking green gas belched from between her impossibly fat ass cheeks and flowed freely into space. The force of her apocalyptic fart shook even the space stations in orbit and pushed the ones closest to her immense booty into a higher orbit.

Amber was in heaven. “MORE!! MOOORREEE!!! MORE ASS!! MORE GAS!!! YEESSSSS!!!”

Bill’s face was mashed between Amber’s comparatively tiny DD’s as he felt the shockwaves of her fart reverberating through her body. Amber’s pussy was gushing and spasming around his cock as she orgasmed in increasingly stronger bursts. The air around them was almost completely saturated with Amber’s fart gas but inhaling it only seemed to invigorate them further. Bill felt his cock stretch a little longer and thicker as he plowed Amber with renewed energy.

The atmosphere of Ambrosia was completely overtaken by a green haze. Amber was terraforming the planet with the mere act of farting. With each planet shaking release she was molding this world into her personal fart haven. And she was loving every second of it.

Bigger and bigger she grew, farting harder with every growth spurt. “Fuuuckkk YESSS!!! I’m never holding back again!!!!”

Her roaring ass cheeks eclipsed a quarter of the planet beneath their soft, pliable mass before finally stopping their growth. What didn’t stop, however, was her cataclysmic farting. Half of the northern hemisphere of Ambrosia was buried under Amber’s ass and the rest of the planet was drowning in her fart fumes.

Amber pulled Bill in for another kiss as her seemingly limitless gas reserves kept flowing. Their tongues collided as they fucked for hours. The thundering roar of Amber’s fart continued long into the night.

How much time later it was that Amber finally stopped farting, neither knew. Bill leaned against the bulk of her ass, exhausted, and looked out at the green haze of gas that covered everything.


Amber glanced over at him, “How do you know that the people of Ambrosia will really be ok with this?”

Bill smirked, “There’s plenty of planets out there that have strict “no hyper” laws. Anyone that wants to avoid something like this usually chooses to live there.”

Amber nodded, “Yeah, that’s true. But this all happened so suddenly. I can’t believe that the growth pills were still in my system and that farting caused them to make me grow even bigger. You’re sure I didn’t crush anyone under my ass?”

Bill laughed, “Positive. People that live on a planet with a woman with a mountain sized ass are prepared for things like this.”

Amber smiled, “Guess I can get back to making videos again… although I think I’ll need some help getting all this ass in frame.” She smacked her booty and a fart echoed in the distance like thunder.

A few months later Amber re-debuted on HyperFarts as Amberosia to the excitement of the entire hyper fart loving community. She posted dozens of new videos showing satellite imagery of her planet crushing ass ripping atomic farts. Some videos were even a little spicier where she introduced her new husband and had some X rated fun while blasting ass at the same time.

Amber and Bill were getting ready to film a new video one day when Bill found a pill bottle under some rubble that hadn’t been cleared yet. It was a bottle of gas enhancer pills!

He brought it over to Amber, “Hey babe is this what I think it is?”

Amber looked at the bottle and grinned wickedly, “My gas enhancers!” She grabbed the bottle. “You remember how I told you that I only took one growth pill before and that taking all ten made me as big as I am now? Well… I’ve only ever taken one of the gas enhancers too! There’s still nine left in this bottle…”

Reports say that the solar system that Ambrosia is located in grows a little more green and hazy by the day.
