"Aghhh screw this!" Kelsi shouted in frustration.
She stormed off from the bathroom door, loud enough for Jada to hear her. There wasn't any time to hang around outside and wait. Her ass had to fart and it had to fart now. Even while walking Kelsi needed to keep squeezing with her muscles, to keep anything from slipping out. She quickly stomped her way to her own bedroom and slammed the door behind her. Finally she was alone and in private where no one could hear her. A sigh escaped her mouth, full of relief that she made it to her room.
Suddenly a sharp pain came from her guts. Kelsi buckled over wincing. Her intestines felt like they were being tied in knots, after holding in her gas for so long it was no surprise. She put a hand on her ass and could feel something growling fiercely within. Kelsi didn't even need to push with her anal muscles. Closing both eyes, all she had to was relax and the gas came shooting straight out. A huge monster of a fart blared out her asshole, finally free from being locked inside her body. Hot fermented winds warmed her panties while the bubbly sound of her release bounced off the walls. Kelsi's fart was extremely loud, the noise of her ass sounded like a trumpet had been trapped under her clothes. It was a good thing she let it out in her room, her cheeks slapped together creating a boisterous ripping noise.
She could smell her foul scent stinking up the room. It was gross, but she was used to how bad it could get. Even so, she hadn't had a fart this big in a long time. The amount of gas coming from her butt felt unending, just when she thought she was done more bubbles of pressurized air came shooting out her backdoor. Subconsciously she bent forward, sticking her panty-covered ass out. The smell was getting even worse, but despite all this she had a smile on her face. Kelsi's mouth was agape with relief, passing this much gas at once felt amazing. After holding it in for so long, ripping a huge fart in the comfort of her own room was oddly pleasurable. A small sigh of relief passed through her pink lips.
"Ahhhh..."
The fart raged on for over ten seconds, vibrating her healthy butt cheeks. The girl let it all come out until her ass sputtered the last remaining bubbles of air. Finally, the deed was done. She felt satisfied, and thankful that she didn't let out something that big in front of Sunny or Jada. The stinky smell of her gas had filled the bedroom, so she cracked open a window. In a few minutes it would dissipate. Her panties however would take a lot longer. They were warm on her backside and absolutely soaked in gas, a smell that would remain for some time. Kelsi decided to take them off and let them air out before the stink started to cling to her. If she put them in her pile of laundry they'd get washed eventually.
With her old panties taken off, Kelsi searched for a pair of fresh ones to replace them with. But what happened to you during the great event?
----
Deep in the croaking darkness you were choking on Kelsi's gas. You were still stuck on the wrong side of her anus, the dark pit of wrinkles clenched together to hold in her fart. Muffled outside and far above you could hear her powerful voice, she was talking to someone. The person was talking back, you tried to listen to what they had to say but their voices were interrupted. Your friend's ass groaned loudly, and more milky hot gas bubbles rounded the corner of her bowels. The awful thick stink reinvigorated your senses and caused you to gag, just how much more disgusting smells could this girl's body produce?
The horrible feeling of needles in your chest took hold of you again. With even more gas being added to the chamber, it was becoming harder for your lungs to push out any air. In a matter on minutes you would slowly suffocate, your tiny body left to die in Kelsi's butt. Suddenly the giantess started moving again, and your body jerked forward. Wherever she was going, she was going there fast. Your head was getting foggy but also you were being pumped with adrenaline. A large slam was heard in the distance. After a few more steps the giantess stopped moving.
Everything went still for a second. A slow growl from the girl's colon punctuated the moment. Underneath you her anus quivered. You threw your arms forward to stabilize yourself but at that moment the anal muscles relaxed. All at once the wrinkled chasm widened and created a portal to the outside world. Instantly the pressurized gas bubble sought leeway out the open hole, and turned into a massive tornado. The sticky wet slime keeping you stuck to her flesh was nothing compared to force of her explosive fart, and so your dust-sized body shot out her anus like a bullet.
You were thrown into a mass of jiggling flesh, Kelsi's monolithic butt cheeks rippled from the waves of erupting gas. Huge hurricanes swept you along as easily as a piece of grass, causing you to smash into the blubbery mounds as they clapped together. The sound of her fart was so intense that your hearing was rendered useless. The thunderclaps of her butt cheeks as well as the blaring reverberations of her asshole were too much for such a tiny person to handle. You were pushed away from the roaring anus, downwards through her humongous globes. The hot stinky torrent of flatulence carried you along until you hit a wall of fabric. Kelsi's panties were wedged halfway up her ass from all the running around she did, and now you were caught in the back end of their many threads.
By all accounts you considered yourself lucky. You were spared from ending up in a toilet bowl while Kelsi did her business. You also narrowly avoided a horrible death from suffocating on a fart bubble inside her ass. If anything you were just happy to be free of her bowels, away from the putrid odors and disgusting liquids that coated her intestinal walls. That said, the fart that she launched you out with just wouldn't stop. So much gas had been built up inside her and now you were caught in the process of her releasing it.
Kelsi let out an ocean of gas upon you, huge steaming whirlwinds crashed into your speck of a body. Her fart was so long it felt like it was going on forever. The mighty butt cheeks rumbled together, violently shaking the cloth hammock around you. It was hard to orient yourself in her bunched up panties, the crude wedgie was a labyrinth of folds and weaves the size of a city compared to you. As you tried to hold yourself in place Kelsi's fart hammered you against the fabric. Harsh gales battered you between the tiny threads, leaving you lost in a tangle within a storm. Suddenly the fart grew even more forceful and pushed the panties out of her butt crack, taking you along for the ride. The fabric smoothed out under her gushing winds, like a parachute, giving you a clear view of Kelsi's bare ass while it let out this monstrosity.
You were blasted with an onslaught of fumes that had been fermenting inside her butt for the past couple hours. The gargantuan ass cheeks thundered together, producing deafening noise and a constant stream of gas. The fart shot straight downwards, through the cloth of her panties and into the room beyond. If it weren't for the minuscule tangle of threads holding you down you'd probably be blown off the god knows where. You honestly didn't know girls could fart this much, or this loudly. It was a side to Kelsi that she always kept hidden from you. Yet, here was your old friend, a girl you'd known for years, letting out a monster fart directly on top of you.
You choked on her stench, coughing and hacking up the rotten flavor of farts that stained your throat. Wallowing in despair inside her tornado of gas you prayed for the fart to end soon. Kelsi's butt just kept on forcing more booming bubbles through her asshole, regardless how you felt. She was enjoying the sweet sense of relief from letting out so much gas, loving every explosive kiss of anal air that she obliviously gave you.
After what seemed like forever, the fart was over. You were in a dreary half-conscious state, hardly able to take in what was happening anymore. There was movement, more movement, and then a flood of light. Kelsi's legs slipped through the panties, exposing you to what normal light was again. The aftermath of her gas attack started to rise into the air and spread, as you laid there in the smelliest spot. Soon you were placed in the pile of dirty laundry and Kelsi left to find new undies. You were abandoned by her, but also finally free.
What you just went through was one of the worst experiences of your life. It was disgusting and terrifying and you never wanted to think about it again. Your body felt sore and exhausted, on the verge of passing out. Over time you would start to grow back to your normal size: from a speck, to an inch, to two inches and so on. As for the giant pair of panties, what would happen to them? Did another roommate come in and put them on when Kelsi wasn't around? Or did Kelsi not find any new panties to wear?
