Not for the first time, a foul air hung around the Monroe household. Ben had spent the rest of the morning and lunchtime dealing with the aftermath of Molly’s disastrously destructive gas. The smell had been enough to send her friends scrambling to escape for fear of suffocation. He had been forced to fling open the windows as far as they would go to allow his sister’s stench to waft out of the house. He could have sworn that the flowers in the front garden had started to wilt with the waves of humid, green gas flooding out into the world and polluting the air. Occasionally a passer by would catch a strong whiff of rotten eggs and sewage, their nose wrinkling in disgust as they hastened their step to clear the area. I am sure they would have been shocked to know that the source of such a stink was the now stale farts of a nineteen year old girl. Normally, Ben would have opted to savour every last bit of the toxic air, enjoying the comfort and satisfaction it brought him. However, today was special. Today, Ben and Molly were planning to find out just how rank Molly’s farts could be. Therefore they required a blank canvas in the form of an untarnished room. The duo had of course been given instructions from a strange doctor to measure Molly’s farts at their full capacity. Ben had to admit that he was a little worried about the potential damage later, once his sister had followed the crash diet of gas inducing foods although still very much excited by the prospect.
Molly was in her usual fashion, sprawled on the sofa, in her grey loungewear consisting of some jogging bottoms and a hoodie. She was feeling pretty tired after letting off such an impressive fart, it was surprising how much it took it out of her considering she was such a gassy person but then again that latest fart was pretty spectacular. The nerdy girl was intently watching some sort of video game review on her phone that she was holding only an inch away from the end of her nose.
Ben was quite happy as he scrolled through feeds of social media on his laptop. He knew he had to take it easy considering Molly’s farts were going to only get smellier this evening and was taking a break from what had become ground zero.
“Molly I think we should go to the shops” called Ben from the kitchen
“Huh!” Shouted Molly, not really having heard exactly what her brother had said
“We should go and stock up on food for later” said Ben as he appeared in the living room doorway. He sniffed the air “Ah the smell has pretty much gone from here now” he commented
“You sure you want to be around for my farts later?” Joked Molly as she looked over at Ben
“You bet, we gotta measure them for that doctor anyway”
It was at that moment his phone buzzed. Ben checked the message to see that it was a chat he had with his friends talking about meeting up. He had not really met up with his friends in ages and to tell the truth he did miss them.
“What is it?” Said Molly, noticing Ben’s attention divert to his phone
“Um, it’s just my friends talking about meeting up later”
Molly put her phone down and looked at her older brother.
“You gonna go?” She asked
Ben found himself now staring at Molly’s plump ass, fantasying about the smells she would be producing after she had loaded up on food. On one hand he really did want to see his friends, it had been a long time since he had met up with them. However, there was a reason that Molly was not allowed even half the stuff she planned to eat later when their parents were home. The last time she had eaten beans her farts were so stinky that the family had actually had to abandon the house for a few hours to let it air out. Even Molly was shocked by the smell she made that day.
“No, I’ll stay here”
“Okay give me five minutes” she replied, her eyes darting back to her phone screen.
The siblings had developed quite a relationship. They were almost becoming an inseparable duo. Molly was of course the dominant one and had full command and control over Ben. He did everything for her but she didn’t treat him like any lesser individual. He could lead a normal life but Molly knew as soon as she wanted him under her spell she just had to mention her farts and he would be awaiting orders.
Ben and Molly trudged down the road managing to juxtapose each other magnificently. Molly was looking a bit unkempt with her messy dark hair and stained grey tracksuit. Ben on the other hand was looking far more respectable with a neat haircut, denim jeans and a jacket. Their parents house was in a rather nice neighbourhood and they must have looked like quite an odd pair. Despite not caring about her appearance, Molly’s undeniably sexy body was still able to shine through her dull attire and her massive rear end was bouncing from side to side with each step she took.
They made it to the store, a fairly smart little shop only around five minutes from home that always seemed to be busy.
“Right what do we need?” He said as he grabbed a basket
Molly giggled “Follow me” she said as she bounded off down one of the aisles.
Ben hurried off after her and they came to a halt on front of one of the staples of gassy foods.
“Okay, lets get a pack of these” said Molly as she put fours cans of baked beans in the basket. “Ooooh, I love these too” she said as she grabbed another four pack, this time consisting of refried beans and tossed those in.
They continued down another aisle with Molly examining each shelf as they went, looking for the perfect blend of food.
“Aha!” She exclaimed as she squatted down to reach a bag of lentils. Her grey leggings were stretched to their maximum to try and accommodate the massive amounts of flesh nearly bursting out the seems “I have no idea why, but these always give me so much gas” she said with a smirk, “speaking of which…”
Bbbbrrrppttssss!!!!
A soft, bubbly fart lasting about 4 seconds escaped from Molly’s cheeks as she squatted down. It was by no means her loudest fart but it was loud enough to attract the attention of a couple who were standing a few feet away, both of whom gave disgusted looks in Molly’s direction. The smell was her signature sulphuric stink that quickly began to pollute the aisle. It was a smell that far outclassed any normals person’s worst case of gas. Despite, it’s relatively short length, the eggy gas cloud was a force to be reckoned with. Ben grinned as he took a nice whiff of the smelly air. Molly stood up casually fanning her ass as, which only succeeded in spreading the smell to the poor couple nearby. The girls’ nose wrinkled as the wafts of the teen’s sewer like gas filled her nostrils and she was soon fanning her face frantically to try and keep the smell at bay. Her boyfriend was doing his best to stay strong but Molly’s stench was far too smelly for that.
“Ew that stinks!” Exclaimed the girl as the gravity of just how toxic the gas was overpowered her, her face contorting into a look of total disgust.
No sooner had the smell drifted into their path before they were quickly walking in the opposite direction. The ability of Molly’s farts to linger no matter how many times you fanned your nose was impressive and It had definitely caught the young couple by surprise.
“It wasn’t even thaaaat bad?” Said Molly tilting her head towards where the couple previously stood. She took a sniff of the air, “Phew!okay, well at least compared to what I am going to be releasing later” She added with a laugh, standing up and handing the pack of lentils to Ben.
Molly patted the gas factory that was her stomach. It had been making all kinds of noises since the morning. The late night and copious amounts of beer she had drunk the night before had really messed up her stomach and she sensed that she was going to have to let off a bit more pressure soon.
The brother and sister duo continued their way around the store, adding everything they could think of that would only increase Molly’s gas production; cabbages, broccoli, eggs and tuna. They even found a couple of pre made protein milkshakes to wash everything down, Molly chucked one in the basket before chugging the other one as if she hadn’t drunk anything in days.
“Whaaaat, I was thirsty! Said Molly, noticing Ben’s disapproving look as she wiped her mouth with her sleeve. He knew how quickly Molly’s stomach could go from relative calm to all out chaos and ideally they wouldn’t be in the local store when that happened.
“Wow, this is getting seriously heavy” moaned Ben as he struggled to cart around the mass amount of food. He followed behind Molly who was bounding along clearly excited by all the food they were buying and leaving a stinky trail in her wake. That was the thing with Molly’s farts, the smell liked to linger. The fumes hovering around her butt were not for the faint of heart even if she had not recently farted. It did make finding her in the store a lot easier as Ben just had to follow his nose. He rounded a corner to find the excitable Molly standing in the freezer aisle, staring at all the ice cream on offer.
“Okay we need some of this!’ She exclaimed as she pulled out two tubs of Ben & Jerry’s from the freezer and tossed them into the basket. Ben grimaced as the sudden additional weight, strained his arms.
“We really should have got the trolly” he said to himself
Grrrrrrggggglllllluppuuup
An ominous gurgle sounded from the depths of Molly’s bowels as they got to work digesting the protein shake she had just taken in.
“Do we have everything?” Asked Ben
“I think so” replied Molly as she peered into the basket and sorted through the items.
***
Molly sighed, patting her stomach.
“Phew, that was a serious meal” she exclaimed having just devoured anything that would contribute to giving her lots of gas. Her diet for the last few hours had consisted of beans, eggs, cabbage, onions, cheese, broccoli, lentils and plenty of ice cream to really get her lactose intolerance going. She was pretty much a gas factory having been attempting to hold in the farts that her gut was already producing. Some had escaped and she almost felt worried for Ben. She consoled herself with the fact that he’d asked her to make her farts as smelly as possible and that they needed to do this fest for that researcher.
“You sure you want to be in the firing line?” Said Molly with a smirk as she got changed into her fluffy pink pyjama bottoms “Because honestly these farts are going to STINK so bad! So you’re in a dangerous position.” She warned
“I can’t wait” replied her excitable brother as he picked up the small measuring device they had been given, it looked similar to a decibel meter although was a little smaller.
Molly rolled her eyes before climbing into bed. She shimmied her shoulders as she got comfy underneath her big duvet and giggled as Ben joined her down below, his face snuggled up to her giant butt. She lay on her front, her duvet pulled all the way up over her shoulders so just her head was poking out while she scrolled through her phone, giggling every so often at another funny video. Her stomach was busy too, churning and gurgling away as it processed her dinner. It was a combination of foods that would give anyone awful gas, let alone someone with a digestive tract as active as Mollys.
She wiggled her plump rear from side to side as the gas started to make its way down through her gut, she could already anticipate the relief from what was about to happen
BBBRRRRPPTTTTTRRRRPPPTTTTTTSSSHHHHHHHHHH!!!!!!!!!
A monstrously powerful fart boomed out from her butt. Molly smiled to herself as the pressure in her gut subsided ever so slightly.
BBBRRRPPPTTT!!!!
FRTRPPPOOOPOFFFFSSHHOOPPPSSSHHHH!!!!!!
BBBRRRRPPPPPPPLLPPLLPSHHHHSSSS!!!!!!!!
Three more absolutely disgusting sounding farts roared and bubbled out of her totally around 50 seconds of gas release. The nerdy girls eyes rolled as she felt the immense relief in her body. Her stomach finally rid of the toxic fumes which were now happily polluting the air under her duvet with such a devastatingly foul stink that she was thankful it was being contained under there.
Down below, in what could only be described as a death chamber of violently stinky fumes, her brother Ben was moaning with a mix of pleasure and concern for his safety. His face had been resting between Molly’s two huge butt cheeks, his nose nestled perfectly between them. There was a reason that Molly had chosen to contain these farts in her duvet. The smell she produced was just so foul and so overwhelmingly smelly that she couldn’t just hotbox her room like she usually did. Molly had been a little concerned to let Ben enter into her Dutch oven but he had been desperate to experience it. His face had just been blasted with over a minute of farts so rank that the girl who produced them couldn’t even stand them. The heat and the smell now surrounding him as he lay trapped under the duvet was so intense he felt like it was dangerous for his health. He took another whiff of Mollys bum which was now like the smoking barrel of a gun after firing a round. He was struggling to contain his boner that was now raging so aggressively he thought he was going to explode any minute.
“Whats the reading saying?” Called Molly, suddenly realizing the reason they were here.
Ben had totally forgotten to even check the meter as he was so overwhelmed by his sisters farts.
“Oh…umm” Ben stammered as he searched for the device that was somewhere under the covers. He finally found it, his hand grasping around it as he brought it up to his face and strained to see the screen.
There was a bar on the side and it was currently full to around 90%. Ben was. Not sure exactly what the readings meant but he figured that the result was pretty reasonable considering how rank Molly’s gas had been.
‘Its pretty much nearly maxed out!” He answered to Molly
“I bet I can max it out!” she giggled, seeing it as a challenge.
About 15 minutes after Molly had let off her storm of farts she put her phone down and peeled back her duvet ever so slightly to glance inside her Dutch oven. If you could see farts then she was confident that a thick plume of green gas wafted out from the small gap and into her face. Her eyes widened in shock as she quickly pulled the duvet back down to seal off the air supply once more.
Cough cough “Oh my God!” She gagged through coughs. “That is soooo smelly!!”
She pinched her nose, the awful meaty stink mixed with the sulphuric stench of rotten eggs proving too much for her to handle.
“How are you even alive down there?” She asked through a nasally voice. Her fingers firmly clamping her nose shut.
Brrrrrptttpptptopopoppppopopopppssssssfffhhhhhhhooppoopoopsshhhhhhhhhhhhhh!!!!!!!!!!!!!!
Before Ben could answer Molly let another stinker go. A 20 second soft but bubbly fart rippled from her ass and undoubtedly straight into her brother’s face. It was not as loud or powerful as her previous farts but she knew it was carrying some serious stink, just from the heat she could feel as it bubbled out.
Molly burst out giggling “Sorry! That one slipped out, God it must be rank down there, PHEW!” She said as she shuffled her bum around, grinding the fumes all over Ben’s face. The moans of delight and sounds of frantic sniffing could be heard from under the covers as Molly picked up and went back to scrolling.
Ben spent the next few hours basking in the ungodly stench of Mollys post dinner farts. She would shift her position around occasionally and Ben would readjust to make sure his face was not too far away from her death cannon. It was then than Molly started to feel a different beast brewing within in.
“Ugh sorry Ben, I think these next farts are gonna seriously reek!” She said as if her gas up until that point had been pleasant. She reacher her arm down to find the back of his head before gently pushing his face into the confines of her flesh.
Fffffrrrrppppttttt!!!!!
FRRSSSOOOOSSSSHHHHHHHH!!!!!!!!
Two big and airy farts poofed out Mollys butt, carrying with the it the sinister pre poop stench.
Molly giggled knowing full well the total death cloud she had just let go in her brothers face.
“Sorry, I bet those stunk” Said Molly almost with a touch of concern.
She giggled listening to the moans coming from down below and she peeled back the duvet just enough to get a quick whiff of the stink she was producing.
“Woah!” She gasped, frantically fanning her hand in front of her face “That fucking reeks, I’m gonna have to take a dump”.
Ben’s ears pricked up at the sound of this, he knew that Molly was gonna have to unload a mega dump at some point this evening.
Molly slowly wriggled out from under the covers, trying to contain as much of her toxic gas as possible. She stood up next to the bed, rubbing her stomach as the unmistakable gurgling and churning sounds from her stomach signaled an imminent release. She waddled over to the door before stopping to call back to her brother.
“Cmon Ben, you think I’m going to unload this in the toilet?” She said rolling her eyes
Ben quickly scurried out from under the duvet and hurried off after Molly who was making her way down the hall.
Once in the bathroom Molly closed the door and locked it shut before turning to smile at Ben who stood in the room.
“On the floor” she instructed as Ben obediently got down and laid himself down.
Molly stood over him looking down at her older brother.
“Oh man, those farts were nearly lethal!” She exclaimed as she opened up the bathroom cabinet to grab a few items. “I honestly don’t think I can take the smell from this dump so I hope you don’t mind me using this” she said seductively as she took a nose clip she used for swimming and popped it on her nose. She then grabbed a pair of disposable gloves and pulled them on to her hands.
“I know this is gonna stink so so bad so I need to peg my nose for this one” she giggled as she turned around so that her giant butt was positioned over Ben’s face.
Ben did not even have time to react before the floodgates opened. As soon as Molly’s butthole opened up there was no stopping what was to come. A huge, thick and slimy turd started to coil out of Molly’s ass and slowly lay itself on Ben’s face, the stench was insane. Somehow its stink was a more potent version of her gas and she wasn’t stopping there. Three more huge logs fell out of her ass, adding to the pile on Ben’s face.
BBBBRRRRRRPPTTSSSS!!!!!!!
“Ahhh Oh my, here we go!” Exclaimed Molly as she blasted out a destructive wet mess of diarrhea, totally covering Ben’s upper body in a mud like substance that stunk like a sewer. If anyone else was in this bathroom then they would have passed out from the smell, flies might have even had a tough time sticking around in there.
“Oops, sorry Ben” giggled Molly knowing full well how badly she had just covered him in her mess
BBBRRRRRRRRSSSSSSS!!!!!
FFFFRRRRPPPTTSSSSSSSSS!!!!!!!!!!
Two farts roared out of her butt, carrying with them bits of poop they clung to her ass, It was tough to even make out a person lying below Molly at this point. Ben’s head was totally covered and more of his body was smeared.
“Oh I bet it stinks in here!” Laughed Molly who was enjoying her nose being plugged. She turned around to see her brother lying there covered head to toe in her crap. Molly ignored the raging boner in his pants although she was pleased to know he has in total heaven despite the situation.
She reached down and with her gloved hand began to dig through some of her shit to clear a space for Ben’s nose. She felt a sharp inhale as he could breathe a bit easier and he moaned in delight
“Can’t have you not being able to smell all this!” She said as she wiped her bum, using a whole roll or toile paper. She tossed the loo roll into the pile of shit on the floor known as her brother and was about to leave the bathroom when she noticed the measuring device still in Ben’s hand.
She reached down to inspect it and noticed the gauge had a cracked screen although she could make out that the reading had gone all the way to 100%.
“Guess I did manage to max it out then” she sniggered before turning to exit the bathroom.
Molly was downstairs in the living room having stunk out her bedroom and most of the top floor. She had opened up all the windows upstairs to try and air it out and was enjoying just chilling and watching some tv, now feeling a lot less bloated. Ben was upstairs and clearing up after the mess she had made, the bathroom and his body was covered in Molly’s waste and it was a task that only he could perform. Molly loved having such a dedicated older brother. A few hours passed when Molly’s nose started to twitch as she detected a foul odor. She sniffed and immediately her face contorted in disgust.
“Ugh, I haven’t even farted, what is that?” She asked herself as she searched for the source of the stink.
She heard footsteps in the hallway and then Ben appeared at the doorway and along with him, the smell of death.
“Oh God, Ben you stink! Like really really stink!” Moaned Molly as she wafted her hand in front of her face.
“I had a shower though?” He replied puzzled
“Well you’re gonna need a few more if you still smell like that!” Replied Molly
Ben trudged back upstairs, reeking of his sister's powerful farts but full of pride for her achievement.
