The Flatulence System

By: Yourmainmanbob

A girl walked across the bustling city of New York, her steps were light and she had quite the peaceful expression on her face.

She wore a simple black school uniform with a black knee length skirt and matching pantyhose. She finished off the look with black loafers, sometimes, it felt like she was getting dressed for a funeral every morning, but she got used to it. The all black was a striking design choice, It contrasted with her light colored skin.

Her figure was petite, unfortunately flat on both ends, and only sitting at a below average 4’11.

This girl was Eiko Komori, a shy, reserved orphan girl who was born here in the americas. She still didn’t know why her parents had her here, or what they were like, more often than not thinking about what could’ve been made her sad. But she wouldn’t let that stop her today. Scruffy shoulder length black hair revealed delighted large brown eyes beneath the bangs.

This world she lived in changed ever since an event nicknamed “The Neo Enlightenment” Took place. All of a sudden, people around the world awakened these systems, systems that gave them powers unheard of.

Being able to control the elements, healing or modifying the body, imposing your will onto someone, summoning beasts… the list went on.

How you could awaken was completely random. There was no known method, or knowing the powers you'd get either. It was like gambling!

The reason for Eiko’s dumb grin was that she woke up one day to see she awakened. She got a big blue box announcing the fact and a claim button, surprisingly very little fanfare, but it still made it impossible to focus for the school day.

She wanted to wait until she was all alone in her room, almost breaking out into a sprint to get there faster.
Eiko theorized just what power she’d get, she hoped it all at least something to do with animals, those beast riders and tamers were really cool..
Appreciating the vibe of the city, Eiko looked towards the sky to see an awakened with wings being followed by another with a metal suit.

Soon, she’d be one of them.. soon she’d finally be freed from the bullying. If someone dared to push her around she’d unleash her godly powers!

The excitement made her hasten her steps just a bit, finally arriving to her complex, she quickly rushed inside to her apartment and fled to her room.

Thinking about who she’d be the first one to tell, she thought about her guardian. Noticing their absence, her guardian was usually out working or running errands. Eiko didn’t really know what she did, she barely came by the apartment. But that was alright, as long as she kept the fridge stocked, Eiko could manage on her own. She learned a lot of useful skills thanks to her environment!

Feeling a bit proud, Eiko confidently called out for the system, she had dismissed it earlier to not interfere with her studies. But again, the anticipation was too much to bare.

The system appeared with silence. The same congratulatory message with a large claim button below it. This was it. This was the moment that would change her sorry life into one of adventure, of success, of romance, of greatness!

With trembling fingers, Eiko slowly hovered the claim button, blessing the stars for good luck, she pressed it.

“Congratulations on becoming a Flatulence Mage! Stats and information are listed down below.”

“..H-huh..? What’s a fla.. flatulence mage..?”

Eiko muttered in confusion along with dread before immediately scrolling down. She knew some powers had weird names, but flatulence mage? What was that supposed to mean?

FLATULENCE MAGE

”O-oh.. oh my god..”

Eiko’s heart dropped to hell itself and never came back up. She wondered who in the world she pissed off enough to get this result, she always thought she did good in her life..

Eiko’s descent into despair was stopped by a notification in the corner of her eye.

“Changes taking place now.. huh? W-what changes..”

Eiko was stumped, before an immense stomach cramp hit her and she kneeled over on the spot.

“G-Gah..! Nnhh!”

It felt like her stomach was twisting in on itself! Her body was feverish, Eiko was rooted in place, a strange feeling began to build up in her gut, it felt so uncomfortable in there… Eiko pressed against her stomach in pain, the feeling just made her wanna..

“Hnngh!”

~BRRrrrpphtt!!

She pushed, a sharp fart rang out, what would become the first of many on Eiko’s stinky journey..

Eiko went red in the face, but before she could do damage control, the bloated sensation came back with a vengeance.

“Uhng.. Again..? Ngh!”

~Phrrttt!

Scrunching her face at her predicament along with the effort, Eiko was in dismay to find that the pressure refused to subside.

“J-just.. just get out of me already!”

With a groan of pain, Eiko grit her teeth in discomfort and pushed harder.

-BRRRRPPHHHTTTHPTT!!


Another fart, probably the hardest and loudest she’d ever let out, but still no relief. Eiko was trapped in a terrible cycle of fart, buildup, fart, buildup…
Her farting got weaker every time, but not by much. Eventually she conceded. Stumbling to her small chair. She took a seat, exhausted, as a strange heat began to build around her waist.

Dealing with the stomach issues, Eiko was too in pain to notice her hips slowly pushing out. Filling with new flesh, Eiko was a boney girl, thanks to malnutrition, but these hips made it seem she had plenty of meals all her life. The growth stopped when there was a clear curve where her waist transitioned into her hips, the warm feeling then moved into her behind.

Her rump thickened out at a stable pace. there was barely anything to work with, But the system blesses all. The small chair Eiko sat on was rapidly losing ground, her cheeks devouring the remaining space before beginning to hang off the ledge. Eiko felt the start of a tightness in her underwear. She looked down confused, only to be met with her thighs expanding.

“Argh!! W-what the!?”

Stumbling off the chair, letting out a meek fart as she did so, she staggered towards the mirror to access the damages.
she looked down at her thighs, in disbelief at how.. how she looked like a different person from below!
The growth seemed to have stopped, but it definitely left a mark. Eiko had curves now, at least on her lower half. She lifted up her skirt to get a view at her rump encased in pantyhose. She didn’t have a ghetto bubble butt or even a nice gym booty. But she had a modest small peach you could appreciate now. A bum perfect for ‘patting’.

One thing that wasn’t welcome was the lower stomach bulge. That part of her gut always felt warm, uncomfortable, and bloated. it made her sick to know she was now producing gas constantly, with a terrible efficiency.

Eiko recalled the figure with wings in the sky, she briefly mused how it must’ve felt to have wings growing out your back.

Definitely couldn’t have been comfortable…

Changes Complete.

Disregarding the system box, Eiko wondered just… how to proceed from here. The system said she could support allies or debuff enemies.. but how? Don’t tell me she was gonna be farting all over them for gods sake! Her reputation was already poor. She was the bullied girl! The orphan! The last thing she needed was to be heard farting uncontrollably.

Eiko bit her lip. Throughout her life she’d always had to play bad cards, what about this was different? Yeah, she was a stupid, embarrassing, fart wizard, but she still awakened! and that meant she could take on quests to earn experience, money, and fame!

Trying her best to quickly move on from the mortifying experience of being non-consensually changed into a fart factory, she strode over to her closet, the bloated stomach seemed to be a new saddening constant, but the instances of stomach pain were fading.

Eiko always had a dream she’d awaken one day, despite being a senior in school, a bit of childish wanting remained. She needed at least a couple things to keep herself dreaming and wishing.

She shifted through her clothes until she reached it. A special box with a scribbled tag, “whenever I awaken” .
The box was brown, with orange stripes running along its side. It had small amateurish drawings as well as a bounty of stickers. It was a perfect cube shape, if not for the damaged edges. The box was old, that much could be assumed.
She lifted the box with a careful touch, setting it on top of the bed. Inside was a large black witch hat, with a purple bow neatly fit around it, some simple black robes revealed to be an bit oversized, and a white plastic mask.
Eiko always thought if she were to awaken, she’d have something magic based, but why all the flair with the outfit?
If an awakened wants to preform quests, then they need to go to a guild. To go to a guild, you need to look fashionable! All the awakened she saw had flashy outfits, personalized items, and something that hid their identity. Well, the small ones did at least. The big shots at the top were sponsored by associations and whatnot..

Lucky for Eiko, it was the weekend. She had plenty of time to get suited up, try and fetch a Guild Id, and maybe even do her first quest!

Changing her uniform top for a simple outfit of a white t-shirt with black skirt, Eiko straddled the large witch hat onto her head with her heart pounding.

This is it. The first step to greatness…

She looked a bit comical with the robes and oversized hat, but it was better than nothing. Looking into the mirror with barely contained glee, the mask caught her attention.

Can’t forget that!

You only really hid your identity if you wanted to be anonymous, and in this scenario, Eiko couldn't bear the thought of one of her bullies seeing her fart like a barn animal.

Ignoring how progressively more wedged in her now ill fitting panties got, she walked into the kitchen, made a simple grilled cheese, looked up the route for the Guild on her phone, and made her way outside all in 5 minutes. It’d be a long walk, but Eiko wanted to appreciate the weather.

And also show off her costume.

————

Eiko pushed open the big doors to the guild, grunting a bit from exertion. Whatever interiors she saw online couldn’t compare to the real thing. Nice looking chairs, cool tables, awesome looking front desk, tired receptionist, the works. Also inside were people from all walks of life, a man showcased tricks with his tamed bird while a woman used wind to juggle apples, there was a teen boy beside her with a greatsword trying to duel a gruff looking man, and to Eiko’s joy, they all had unique costumes on.

As to be expected, she was right to come here dressed up!

On her way here, Eiko received a few odd looks, probably because being dressed as a mage and walking instead of using any transportation spells was unheard of. Or it was the mask, but the former was more likely.
She was a bit of a poser, but she was still a new awakened with many skills to learn!

Walking straight up to the front desk, she realized she was too short to get the attention of the dazed receptionist, instead opting to slap the desk until they snapped out of it.

“W-whuh..? O-oh, hey. What can I do for you today?”

The receptionist was a tired woman whose eyebags had names. She looked down at the big hat beneath her that revealed a small mask.

What’s a kid doing here..? No, never mind, not my business.

“uhm.. I’m h-here for my guild Id.. I awakened today. j-just an hour ago, I think?” Eiko managed to sputter out. Seemed like the confidence boost from awakening and dressing up wasn’t long lasting. But a stinkier problem played part in it as well.
Truth be told, an immense building need to pass gas had built up during her walk to the guild office, seeing the inside took her mind off it temporarily, but it was back, making her tummy gurgle. Eiko underestimated her new stomach. it made so much gas off that single grilled cheese, all in what couldn’t have been more than 40 minutes, her poor anus was twitching..

“Oh, yeah, I can do that, sure. Let me do a quick appraisal on you than we can fill out a card.”
The receptionist began to gather papers in preparation, she bent over to reach a specific file, unintentionally showcasing her rather impressive rear, stuffed in a pencil skirt.

All the while, Eiko was shifting her own rear around, her legs shaking and body trembling as she desperately tried to hold it in. She couldn’t fart here.. not in front of everyone! Eiko had a bad feeling it’d be one of those booming, loud farts, not that she ever had one, but with her new bowels. she expected the worst.

She had to find a solution, there was no way she could make this silent, but maybe she could release it in bursts? It’d be miles better for a sustained barrage than a large explosion.

Breathing heavily in preparation, she slowly eased her hold on her rear, then she-

~BRRRRRPPPPHHHH-!!

“Eek!”

Too much! Too much!

Closing the gates immediately, Eiko was thankful for her mask, blushing furiously as she looked around. People didn’t seem to notice it, as loud as it was… the guild was a busy place after all.

Taking her thoughts back to her gas, she didn’t even push! I-it just came rushing out of her! How was she supposed to do this!? It was impossible!

The guild receptionist hummed a tune as she walked back to Eiko with a small stack of papers and a pen.

“Alright, here we are, I’m going to need you to enter some of your personal information here, as well as your guardians contact info. Will that be alright?”

“M-mgh… Y-Yes, th-tha-
~Brrphrrt!
That’ll b-be fi-
~bGHHRT!
Fine.. ungh..
~brRrraarrpgh!
Thank.. thank you..“

“Uh.. you.. you alright?”

The receptionist looked down in concern, just what was that noise?

Eiko was brought to tears beneath her mask. This went from being the best day to her life to the absolute worst, she should’ve never claimed that awful power..

Her small hand gripped the pen as the smell finally began to spread around her, it was this terrible, cheesy scent. Her farts never stunk like this!

With an uneasy grip, Eiko began to write, sniffing quietly. She was relieved she packed the mask, nobody could see her cry as she sporadically let lose cheesy gas in front of the receptionist.


After finishing quickly, the receptionist accepted the papers, now taking notice of a rather poor scent as she looked over them. scrunching up her nose, she stepped back before holding her palm out downwards toward the girl.

“Appraisal!”

Appraisal, a common skill, but one with many paths, from appraising weaponry to appraising relics, these people often found successful jobs.

Skimming over the pop-up, the receptionist did a double take upon seeing the power listed

EIKO KOMORI
POWER
FLATULENCE MAGE

“Huh.. that’s a new one..”

Shaking her head, she brought her focus back to the girl below her.

“Alright, before I can issue you an id, the guild requests a small example of your power, just to verify. Will that be alr-“

“nnNGH!”

~BRAAAAAAAAAARRRHPPTTTTTT!!

Hands on her stomach, her knees bent, Eiko couldn’t take the pressure anymore as she let out a horrific ripper that announced the death of her social life. A new personal record, at 2 seconds long. Her underwear felt so, so warm. Lodged so deep in her crack… she felt her small bum vibrate the tiniest bit from that fart.

Half of the tavern went silent. Eiko knew they were looking at her direction.

“Um, okay, that’ll do, thanks.”

With a practiced professionalism, the receptionist quickly printed out a guild Id and handed it to the girl, all the while thinking about what you’d need to eat to produce such a noise.

“I don’t think I’ve ever heard someone fart so damn loud.. what the hell? This something to do with being a ‘flatulence mage’ or whatever? Man.. it stinks in here..”

Eiko quickly snatched the guild Id and ran out in a frenzy, hearing some of the awakeners complain about the ‘awful smell’

———

Outside, Eiko was a mess beneath the mask.

I cannot believe I just did that.

She struts into a guild, moseys up to the reception desk, and just starts gassing out the receptionist!

In her socially awkward mind, this deserved 5 counts of beheading. But on the bright side, she was empty!

Well, she was never truly empty. Thanks to the whole ‘hyperactive bowels fart factory’ thing, but she no longer bursting with gas! That was something to celebrate.

Drying her tears, Eiko brings up her newly gotten guild Id. To the left It listed her name, power, level, and rank. There was a picture of her in her costume to the right.

‘When did she snap that…? No, it doesn’t really matter.. I look kinda awkward though…’

She just wanted to grab some food, go home, and sink into a comfortable depression.

Walking down the block, she took notice of some awakeners discussing something with the police. It seemed to be an important issue, as it was getting.. rather heated. One of the awakeners summoned a bird made out of fire, pointing it threateningly at an officer.

“They kidnapped my son! How could I not do something!”

“Sir, if you don’t calm down you are liable fo-“

“You think I care?”

Nothing to do with me..

Eiko promptly sped around them with an agility that surprised herself. Taking note of the way more summons were being brought out.

Summons.. sometimes the main meal of a power, or just an appetizer that adds to it. Usually, at least 1 summon can be found as one progresses their power unlocking traits and skills, and speaking of skills…

“Status! Show me my.. my starter skills..”

Faltering a bit at the end, Eiko really didn’t know what to expect from her power. It could literally be anything! Maybe she could control poisons, or any type of ‘gas’? It wouldn’t be the first time she heard someone get a power that looked unassuming at first glance, but revealed astonishing strength within.


CURRENT STARTER SKILLS

Imbue flatulence - 10 mana
enchant your next emission with a certain property. Available enchants listed below.

- Paralyze

Closest unlock-able property: Cloud

Bubble-guts - 20 mana
Gain a burst of gas, increase emission strength, Give self diarrhea.

Eiko let out a long, long sigh. Her hat seeming to hunch over in grief.

‘that’s what I get for staying positive…’

Turning the corner, She fiddled around with the systems interface, seeing how much mana she had, what godforsaken stat she should upgrade first, she noted her power was classified as “magic” despite being anything but. Thankfully, the magic tag did start her off with 150 mana instead of the usual 80.

Eiko was theorizing how to make the most of a paralyzing fart before hearing noises coming from an alley, she heard 2 girls along with a boy, they sounded aggressive, confrontational.

‘Is this where I can get my first bits of experience?’

The way awakeners got experience was by doing acts that would get you ‘karma’.
A person could awaken and become a crime legend, giving them tons of experience on the path there, but another awakener could rise up and defeat them, giving them the equivalent of a boss drop. The villain would then be put into jail, or specialized containment, where earning experience would become a herculean task.

For Eiko though, stopping some bullies should be easy enough… all she’d have to do was make a big showing, once they knew she was awakened they’d scram.

But as she approached, she started to doubt herself. She was short, skinny, and probably stunk a little…

What if they just.. call her bluff? What could she possibly do in a fight? Is a little gas going to dissuade them from beating her into a pulp? Eiko was scared. Frozen stiff just outside the alleyway. She could see their shadows, would no one else come? Did anybody else care? She felt her tummy gurgle, all this anxiety only made her feel the pressure in her stomach more, that damn permanent bloat she was cursed with, she beginning to feel sick..

‘Deep breaths, deep breaths… no matter what happens, it can’t be worse than what you imagine..’

Gathering her few remaining wits, she walked into the hallway, doing her best to put on an air of confidence.

“Give us the money, Suu! You aren’t doing anything with it!”

“Last chance before we break your arm!”

Inside were a girl and boy both of average height, they wore school uniforms, they appeared to be some delinquents with the the way they fashioned their uniform.
Looking closer there was another girl sandwiched in between the 2, definitely the voice she heard earlier. The girl had unique purple hair that reached down to her waist, and also…

She was quite.. chubby..

The girl had rather large breasts restrained in a brown sweater, a pudgy middle, wide hips and a plump bum that slightly peaked out below the mid thigh skirt she wore. The dark thigh highs she wore squished her fatty thighs and led down to thick calves and cute brown boots. She was rather tall too, standing above both her assailants at what looked to be 5’9.

The boy held her down while the girl threatened her, the purple haired girl was rather calm despite the dire situation. Maybe they’ve done this before? Maybe she didn’t have to help out..

‘No… stay focused.. I can’t back out now.’

Eiko made her presence known with a resounding cry of justice.

“Hey! You t-two.. leave her alone.”

Man, she was so lame…

The two bullies looked over at her direction. Seeing a short girl dressed in oversized robes, a large witch hat, and a mask shaking like a leaf… it was hard to take her seriously.

“Yo, kid. This is none of your business, go home to your parents or something..”

“I’m not a kid! I’m an awakened, and if you don’t stop harassing that girl, I’ll show you what I can do!”

Eiko felt pretty proud about that one, totally redeemed herself.

Wait, why was the girl walking over here?

“Alright… I’m not a fan of this, but you’ll thank me later..” Sighing, the delinquent girl first said something to the boy, then she stopped right before Eiko and leaned over her.

“Just go home… last warning.”

“Y-you think I’m scared of y-“

Eiko’s triumphant comeback was cut short when the girl violently shoved her to the ground, the impact wasn’t kind, despite her small frame.

“Ugh! I-imbue paralyze!”

In a panic, Eiko tried to cast one of her spells, she felt something begin to cover her hands, but that was it.
The girl kicked her side, Eiko groaned in pain as she rolled across the alleyway, why wasn’t this working!? Trying again, she sensed what was probably magic coat her hands, but nothing else. The girl reeled back for another kick. Getting desperate, she used her other spell.

“ah..! Bubbleguts!”

Still, nothing. Just the same sensation of her hands being coated in magic.

Being kicked in the shoulder this time, sending her crashing into the side of the building. Eiko’s facade cracked. She crawled away from the delinquent girl. curling up into a ball when she got close.

“n-no.. I’m sorry.. I’ll go back.. I’ll go back!”

Muttering in fear, she curled inwards further, her hands touching her stomach.

And that’s when it happened.

…gggrrrpphhgggrr…

A deep, ominous gurgle from her stomach was heard, Eiko all of a sudden felt tons of gas rush into her system out of nowhere, she felt like a balloon being inflated, her fingers met resistance as her tense tummy continued to expand, Eiko wanted to vomit, what was happening to her? As If the building gas wasn’t enough…

Eiko felt the terrible, pressing need to shit.

A terrible cramp racked her body, Eiko had never felt such a desperate need to go, this.. this wasn’t natural! It appeared so quick, so fast, it felt like a raging wave was pressing against the gates of her anus, was she.. was she gonna have an accident? Right here? In front of the girl she wanted to save?

“nnnghhh.. n-no.. stop..”

“I can’t hear you, speak up!”

Eiko was like a small animal, trapped between the alleyway wall and a predator. But all animals have a defensive mechanism, and Eiko was about to involuntarily show hers.

“ung..! I.. nnNRG.. I’m sorry, I-I’m sor-hrrrGGGNNHH!!”

Pleading with her assailant as much as her bowels, Eiko could do nothing as her anus opened, unleashing a terribly wet fart.

But her body wasn’t done yet.

Eiko was in a daze as she lifted her ass into the air unconsciously, before her body evacuated the entirety of her colon. The bully watched as Eiko’s skirt seemed to bulge just the tiniest bit, as watery feces dripped onto her thighs and began making a small puddle of filth below her. All the while, she was still farting, they were all wet, terrible sounding farts more comparable to a sick cow then a petite girl like herself.

And the smell..

The smell was putrid, just the rank smell of shit. The bully grimaced before trying to step back.

‘Ugh! This kid just shit her pants! What the hell? I’m gettin away from that.. wait.. why can’t I move…’

The bully was rooted in place, a loss of sensation beginning to spread to all her limbs. On the other side, also rooted in place was Eiko.

“UGHN! m-my stomach!!”

Crying in agony, Eiko felt the sickening experience of having a mess rub up against her cheeks, her skirt needed deep cleaning, her pantyhose was ruined, and her panties..?

Her poor, poor panties…

Packed to the brim with semi solid waste, her undersized panties went from a neat simple white to a deep, dark brown near the back, all the mess only made her wedgie even worse, a sickening slimy feel among her crack.

This was officially the worst day in her life. Nothing could compare to this.

With one final gush of gas and filth, Eiko could only let out a broken sigh as the cramp faded, turning her neck to get a look behind her, she was shocked.

The bully.. was flopped over like a fish! The boy, seeing his partner now suddenly on the floor, released the girl and rushed over.

“Rena! You alright? geuh! What the!? It fuckin stinks around here!”

Glancing over at Eiko, he took one look at the state of her bottom before deciding to hightail it outta there with his partner in crime. His thoughts were a mix of “this is so not worth it” and “Why is Rena not moving despite her looking at him”

Eiko watched as the purple haired girl slowly walked towards her. She expected disgust, disdain, but was surprised when she was thanked.

“Woah.. that was amazing!! How did you do that? Can you teach me?”

Eiko, still on the floor. Was speechless.

YOU HAVE LEVELED UP!
-stopped extortion

“I.. uh.. uhm..”

“I always knew farting had potential! Can you train me to fart like you? I wanna be the strongest farter ever!

This girl appeared to be a bit.. unique.
