THE GASSY COUSINS 01

THE GASSY COUSINS
By: SellCon2762

Sam anticipated the family gatherings on his mother’s side of the family more than his father’s side, the one with his actual last name. The reason was simple; he enjoyed the former and disliked the latter, basically because his mother’s side of the family had kinder, warmer people than those who bore his last name. On his mom’s side were four cousins, who were all actually in their 30s and 40s, with Sam himself just turning 25, but it was his second cousins that were the more interesting and more his age. He was always the oldest among all the second cousins, but the truth was he was captured between understanding the adult world of his cousins and the child’s world of his second cousins. The two oldest of his cousins though were the most interesting, Briana and Kelly.
The two girls were sisters among a family of four kids, the younger two being boys, they were also the most mature of the cousins, Briana was almost 20 and in her second year of college while Kelly had turned 18 very recently. Both were very sweet girls, kind and considerate and morally upright people. Briana was a true beauty in her own right, a girl who was a couple of inches taller than Sam’s 5’6 height, her dark brown hair flowed down in a natural, if slightly chaotic manner down to her breasts, which were modest C cups that filled her chest region decently. Her smile was intoxicating and more of a sign of just how sweet of a person she was. She was the kind of person who could get along in college with no problems and have friends without being morally corrupted by anything. A pair of black jeans formed around the long legs that Briana possessed and her pert rear end, sticking out slightly as her cell phone protruded against the right back pocket.
Her younger Kelly was a tad bit younger but was filling out very nicely in her own regard. Even though she was still a high school senior, she had actually filled out her body a little better than her older sister. On a height level, Kelly was even with Sam, but an inch or two shorter than her sister. Her breasts were about the same size as Briana’s and they filled out her pink T-shirt very well, it was within her blue jeans that her ass really shown. It was a real delicious bubble butt, one her asscheeks that were nearly the size of volleyballs, Kelly had definitely won the ass lottery and given her sister’s decent-sized rear that was a complement. Her brown hair was pulled into a ponytail that while her glasses gave her a bit of a geeky look. In terms of behavior though she was very similar to her sister and to her family. They had raised the two of them well, even with a moral Christian background they were allowed to expand their horizons and interact in a way with friends that made then likeable people.
Sam watched Briana and Kelly grow up, the oldest of his cousins and saw them grow into beautiful young girls and mature teenagers, passing into adulthood as the envy of any guys who saw them. His love for his cousins had always stopped short of complete incest, he never sought any sexual relationship with them but he would fantasize about them at times. This naturally merged with Sam’s ongoing fetish for farts and scat, something he had picked up over the years. The problem for Sam was that he had few female friends, so his two cousins were always good choices of people that he could fantasize ripping enormous farts, since he saw them regularly. As they grew up even more, Sam tried to resist the urge to see them in the kind of light he saw other farting models, but alas that did him no good. Even so, nothing had ever become of the fetish until things were kick started for a 4th of July picnic that was being hosted at his house.
It was an eventful day as far as Sam was concerned but was a regular family get-together for everyone else. The food of choice was typical for such an event: hot dogs, hamburgers, cole saw, chips and of course baked beans. He ate his regular fill of food and watched the other family members eat as well. In particular, he was interested in what his two cousins were eating, sitting across from him at the table along with the other cousins, both of their plates were loaded with the creamy brown baked beans and he saw them eagerly eating them along with the other food. Up to this point Sam had never witnessed either of them fart, or any of his family members for that point, everyone was far too modest to let such an outburst occur. But as he watched his cousins eat their beans he thought only of the processes that must have been taking place in their bellies, the conversion of the beans, along with the meat and starch, being produced into something that might leave their asses. He carried on a regular conversation with the two of them about normal items, it wasn’t until one of their brothers, a younger 14-year old named James had addressed Briana.
“Oh boy…you’re eating beans…you both are eating beans…looks like we’re going home with the windows down tonight!” Said James as Briana pushed his body back trying to get him to shut up on the issue. She took in another bitefuls of beans and another swig of her cup of Coke as she allowed for more beans to ferment on her stomach. Sam had never thought about the issue of her farting being brought out but hearing what James was saying he decided to push the issue a little further.
“What did he mean by that?” Sam asked, knowing very well what James was alluding to, he knew what beans did to someone’s digestive tract.
“Oh nothing…he’s just playing around.” Briana said giggling as Kelly looked at her with a devious smile. Sam had gotten the slight impression that the two girls knew of the impact that the beans would have on them and the sad realization that he would probably never get to smell it.
“Yeah, don’t worry about it Sam…James is the one who’s going to have to worry.” Kelly concluded as the two girls finished their giggling spurt before finishing off the meal. The remainder of the meal finished out without any subtle discussions about the girls’ bowels. Sam kept on thinking about what James had said about Briana and Kelly. The next hour or so went on without any incident of significance, the family had broken off into different groups and that left Briana and Sam in a similar region outside the house. Kelly was nearby talking with other family members and Sam could still think of nothing else but the beans and other foods digesting in Briana’s and Kelly’s bowels.
A couple of couches had lined the edge of a wooden deck where several family members had been gathering. Sam and an uncle of his were sitting on one couch while Briana’s mother and father were lounging on the other. A TV screen was positioned so that Briana’s father could watch it while lying down on the couch. Her mother was sitting upright on the end of the couch closest to Sam while caressing her husband’s head. Briana had walked back out onto the deck and started walking up to her parents. She looked really good with her pair of khaki shorts, showcasing her bubbly ass to all and a white tank top shirt on top. Even if Briana was a conservative girl by beliefs, she knew that she had a prized body to show off and wasn’t afraid of that, after all there weren’t any perverts or anything in the family. Sam paid the scene no attention at first, continuing to fidget around with his smartphone that he had on his person. Briana walked right up to where her mother was seated and turned her back on her mother in a non-indicative way. At first it seemed like nothing was going on with this, until Sam heard a cry out from Briana’s mother.
“Briana Elizabeth! What’s wrong with you?” Her mother cried out as she began inhaling the raunchy, rotten egg odor that was emitting from Briana’s khaki-incased butt. Sam started to take notice as the smell from Briana’s butt, despite being in the outdoors began to spread around the deck area. Briana’s mother was quick to get up off the couch as her daughter laughed her ass off from the fart she had cut. It was a really pungent aroma that immediately got Sam aroused, at long last his vision had actually come true, he had smelled a fart from Briana. His heartbeat started going as he wanted to pinch himself from this reality where he was inhaling his cousin’s fart. Still, the more he breathed, the more he liked. It was a typical baked bean-produced explosion of gas that had seeped silently through Briana’s pants and into the air, attacking her mother like a furnace of hot air. Her mother had retreated to another part of the house as she complained about being in a “gas chamber.” Briana just smiled as she sat down on the couch and rested against her father, who amazingly was not affected by the gas. Sure he smelled it, but it was nothing to him. Sam still couldn’t believe what had happened and was trying to comprehend the event that had just occurred to him. He walked a little closer to his cousin, trying to engage in an innocent conversation of her fart while he continued to inhale her creation.
“Jeez Briana…that was pretty bad.” Sam said with a fake laugh as his cousin giggled at the prospect. She just looked around the area as she continued to bask in her gaseous creation. It was Briana’s reaction to the whole thing that had hooked Sam. She looked rather proud of her creation; she was not embarrassed and had no ill feelings about what she had done. What she did with her mom was honestly just playing around but it was the fact that she enjoyed it that enticed Sam.
“She’ll get over it.” Briana’s response was quick but rather about what she had done. She didn’t feel any need to dwell on the topic any more. She had done her bit and released her gas into the world but felt that there was no need continue talking about farts, this was still a formal family gathering after all. After taking in another whiff of Briana’s eggy fart, which had now started to dissipate in the warm summer air, Sam began walking around now with a slightly bigger boner in his pants, intoxicated by the event itself.
Walking around the inside of the house, he had caught up with Kelly, wearing a pair of tight black jeans that really punctuated her bubbling rear end, he had wondered about her farts as well but wasn’t too concerned about that at that point, after all with Briana farting he felt that his need to experience the flatulence from his cousins was already satisfied.
“Did you see what your sister did back there?” Sam asked, trying to continue the conversation about farts, albeit in a subtle way that didn’t raise any alarms. By this point, Kelly had already talked to her mother and knew very well what had happened.
“Oh Briana farting in her face…yeah I know.” She said with a straight face, looking out toward the leftover food that remained in the kitchen.
“Is she always like that?” Sam asked, trying to see if there was any story behind his cousin’s gassy rear end beyond what he had just witnessed.
“Oh God is she ever gassy…she has these rotten farts all the time, it’s the worse.” Kelly’s remark was not what Sam had been hoping for, it just gave him more fuel for his own fantasy with Briana and to hear it from her sister that his oldest cousin’s gas was quite potent on what appeared to be a regular basis made him a little harder.
“So I guess those beans won’t help?” Sam asked.
“Nope.” Kelly said laughing as Sam could not only ponder what Kelly was alluding too. He had already smelled one fart from his cousin, could there be more on the way. To give the impression that he was not prying too much into his cousin’s flatulent lives he continued to the conversation by moving on to another topic before walking away from Kelly. He still would have another hour or two before his own mother and sister would be ready to leave and go on home, but in his mind the smell of Briana’s silent fart there on the deck would remain engraved into his memory. He followed Briana around often for the next hour, continuing to talk up different topics to give the impression that he was simply continuing regular chit-chat with her. She was starting her second year of college and given that Sam had recently graduated from college, he knew that it was a good talking subject, a common interest between the two.
A half hour had passed before Sam had become ready to use the bathroom, which had been located in the upstairs part of the house. As he walked up the stairs he saw someone already in the hallway getting ready to enter the bathroom itself. As he reached the top of the stairs he saw the door was already shut. Before he considered walking back down and waiting he began to smell another odor, one that was actually stronger than the previous one with Briana’s fart. It was a rotten egg stench with a strong helping of moldy cheese, garbage and pure shit, all molded into another silent fart that emptied all the pure air in that hallway and changed it with its own. He did not know exactly where the smell had come from, but seeing that the bathroom was closed he concluded that it was from whoever was now using the bathroom. He walked up closer toward the shut bathroom door and detected the sound of whoever was inside. After listening to the mumble for a minute or so as the sound of pants hitting the ground could be heard, he discovered by the sound of the voice who it was: Kelly.
Kelly Marie sat there on the toilet inside the bathroom as she lowered her black pants and pair of yellow panties, both smoldering from the recent SBD that she had cut in the hallway. The stench from her fart had already filled the bathroom and she sighed to herself when she realized two things: there was no exhaust fan and no air freshener in the room. Shrugging her shoulders she knew that the bathroom was going to stink and that there was nothing she could do about it. She sat there for a minute, waiting to summon the waste to her rectum for its release. She began moaning a little as the pressure started getting to her before she finally let loose her first watery fart.
PPPPPPPPLLLLLLLLLOOOOOOOPPPPPPPP!!!!!
A three-second watery fart emerged from Kelly’s rear and into the toilet bowl as the first of three logs left her anus and entered the bowl, splashing as the first whiffs of her smelly creation began to take hold. Kelly bit her lip and started waving the air around her as the smell from her crap started to dominate the bathroom. She regretted not checking for anything to clear the smell in the room and felt doubly as bad for this being in someone else’s house. Outside, Sam had pressed his ear against the door in a very subtle manner, as to not to get the attention that someone was outside the bathroom. He heard the first burst of gas from Kelly and grew harder down in his pants from the fact, but the smell from her dump was also getting to him. Even through the crack at the bottom of the door he could smell some of the first raw whiff of Kelly-produced gas and it was heavenly.
“Man those hamburgers aren’t agreeing with me.” Kelly said to herself as she felt her stomach double back on some more pain, her painful dumps were often the one’s that produced the worst smells and she feared that not only would this one be a smelly dump…it would be a really smelly dump. Feeling as if there was nothing else to lose, she pressed forth and started ripping several devious farts.
PPPPPPPLLLLLLLLOOOOOOOOOOPPPPPPTTTT!!!!
BBBBBBRRRRRRRPPPPPPPPPTTTTTT!!!!!
BBBBBBBBBBLLLLLLLLLLOOOOOOOOPPPPPPPPP!!!!!
“God do I got gas!” Kelly blushed as she quietly laughed to herself. After the last fart had let out she started pushing on some turds to emerge from her ass and began dropping several bricks into the toilet, fouling the water with a gross mixture of brown and green tints, leaving a pile of crap in the bowl that was rather impressive even for a girl her age. Sam listened with interest as he heard what sounded like more about to go. He had no idea of what was about to happen when Kelly placed her elbows on her knees and her head on her hands. She started pushing forth to let out more crap and instead ripped a big fart!
PPPPPPPPPHHHHHHHHHHHHHHHHHHAAAAAAAAAARRRRRRRRRRRPPPPPPPPPPPTTTTTTTTTTT!
“Oh my that was big!” She said with a giggle in her loud voice, she was rather impressed at the size of the fart that emerged out of her ass. The fart had rattled the toilet seat and even vibrated the glass walls to the shower next to it. A wave of the most pungent smelling flatulence, perhaps in human history began to fill the bathroom with a wet and heavy fog of rotten egg and cheese smelling gas, hanging over the bathroom like a Fog of Death. Kelly had to hold in her nose for a few seconds as she tried to wave the air around her. There were no windows in this interior bathroom and still no sight of air fresheners at all. After letting a little of the killer odor subside, she began pushing out another series of turds into the toilet.
PPPOOOOOOOOOOOPPPPPPPP!!!!
BBBBBBLLLLLLOOOOOOOPPPPP!!!1
PPPPHHHAAAAAAAAAAATTTTTT!!!!
More pieces of shit came out of the 17-year old’s rear end as they started to fill the toilet, she was now getting close to clogging it as she began pushing out a watery waterfall of shit into the toilet, contaminating it in a way that kept Sam on the floor, trying to hump it to reach a bit of climax himself, immersed in the tear-inducing rotten stench that filled the bathroom and seeped underneath the door to pollute the hallway. Luckily, no one had come up still so as far as he knew it, it was still Kelly and himself and even Kelly was still unaware of his precense.
Still, Sam was in a trance from what he was experiencing. This was heaven for him. Back on the toilet, Kelly started to push and felt another turd begin to crackle out. She giggled, thinking to herself that she didn't know she had to poop this bad. She squeezed and kept her cheeks spread as this turd came out. At first she had thought it would be fat, but not only that. It was becoming super long. She sexily grunted as this monster moved out. The turd was coming out almost like the several hot dogs that she had eaten. She knew that her eating had been a little too much for her and now she was witnessing its results.  The turd was moving slow and then stopped for a moment as she took in a quick breathe before regaining her strength and continuing. She made short attempts at pushing the turd out and it moved a little bit each time. She pushed as hard as she could and giggled in between each attempt until the turd as finally almost out. She shook her cute butt up a down a little on the toilet seat as she continued to get this batch of shit out of her stomach; it was quite possibly the longest turd in her life. Finally she grunted one last time and the turd finally thudded into the toilet bowl. She playfully wiped her forehead.
“Phew that was long!” Kelly said to herself as she could think about the log she had just laid there in that toilet bowl. Almost immediately she began farting like crazy.
BBBBBBBRRRRRRRRRPPPPPPP!!!
BBBBBBBSSSSSSSSSSSPPPPPTTT!!!
PPPPPPHHHHHHAAAAAAARRRRRRTTTTT!!!!
It sounded like a drum going off there in the bathroom as Kelly continued with the series of small farts.  Kelly was crapping her brains out and the bathroom had stunk more and more as she continued her bowel movement. She managed to grunt a laugh as these turds continued coming out. Finally the explosion slowed down a bit, but she was still pooping like crazy. She couldn’t believe what she was hearing from her butt, she had a shitting machine at this moment. Light-brown turds just eased out. She said "Man, I really needed to go" while the turds kept coming. She was farting the entire time too. The explosion actually started again and tiny turds kept falling out. She couldn’t even begin to imagine how big the mess in the toilet was as she passed small bits of wind while letting out small turds into the bowl. Even Sam was beginning to get worried about the size of Kelly’s dump, it sounded like a rougher ordeal than even he was used to, and he never went as far as clogging the toilet.
But all good things had to come to an end and Kelly felt what seemed to be the end of her bowel movement at hand. She started pushing forth and another series of farts came out as she began letting go her last bits of crap, all small logs compared to that super-sized log she had let out earlier.
PPPPHHHHHHHHAAAAPPPPPP!!!!
BBBBBBBLLLLLOOOOORRRRRPPPP!!!
BBBBLLLLLLAAAAAAAAAAAPPPPPPPP!!!!!
“Will this ever end?” She sighed to herself as she felt the last of her watery waste enter the toilet bowl, a series of liquid and solid crap, filling the toilet a little more than before. After another minute of this she had to take a breather as she had felt that her duty was finally over. The last bits of watery crap and piss left her butt as she felt the crap had finally ended. Sam continued hovering his nose underneath the door as he inhaled all the vicious vapors that were the result of Kelly’s dump. After hearing her finally wipe her butt and get off of the john he quickly got up and walked his way down the carpeted hallway back toward the stairs. He was timing the movements so that it would seem like he was just walking up the stairs as Kelly would walk out of the bathroom.
Back in the bathroom, Kelly tried to use the plunger to get some of massive crap to flush, but could only manage some of it. She thought about it for a moment before deciding that she at least was going to shut the lid over the toilet and head out to get some air freshener. Pinching her nose and waving the air around her butt she tried to get rid of some of the smell, at least in her own mind. After flushing the toilet with only a little success she decided that the best thing to do was to bolt and mend the damage at the right time. She opened the door and Sam, on the next to top step of the stairs had begun his movement to give of the deception that he had not witnessed any of Kelly’s dump. He started walking toward the bathroom as his cute 17-year old cousin had just opened the door and walked out.
“Oh hey Sam…I wouldn’t go in there if I were you.” Kelly said with a smile on her face as Sam was more than content on heading in anyway.
“Don’t frighten me Kelly, I’m not afraid.” Sam’s language seemed to indicate that he already knew what he was walking into and that he was not going to let the smell get to him. He walked into the bathroom not fully prepared for the copious amounts of stink that greeted his nose. He walked into a hazy bathroom and stood there for a moment, making sure that Kelly had already walked down the stairs. His eyes watered and his nose got a little red from inhaling all the foul smells that had floated around the room. It was sticking his head into a septic tank, inhaling a boatload of wastes from a cow that had just released its hefty payload into a pile. There was little difference from being in an animal waste facility, inhaling vapors that were almost too harmful for anyone to understand. Sam had always had a thing for the younger of the two cousins, even staring at her butt a couple of years back and watching it grow and bubble out more each year, but this just made him go nuts.
He looked into the toilet bowl and saw the mess that his younger cousin had left in there. He could see what looked like little mounds of crap floating on top of what was water, which had since merged with the crap to liquefy it some more. On top of all this was three snake-like pieces of shit, with a fourth one that was much larger than the others, about as thick as a soda can and about half a foot long, it was impressive even by his standards. Steam floated from the pile of shit and into the surrounding toilet bowl as evidence of the still warm nature of the crap that had just previously been inside his cousin’s bowels.
He kneeled before the toilet and stuck his head into the bowl and started taking about the strongest whiff of his cousin’s crap as he could. The rush he got from the experience was more than he had ever expected to get from such a thing like this. He never found the smell of his own crap or someone else in his immediate family’s as enjoyable as he did this, it had more power to it than he could ever even imagine. It continued to have the smell of rotten eggs and maneuver, enhanced by his uber-closeness to the source of the dump. After taking in several whiffuls of the strong and pungent odor of his cousin’s dump he slowly lowered his head out of the toilet bowl and started to acclimate himself to the slightly less-smelly air. After examining her load for one more time he opened the door and saw his cousin was about there with a can of air freshener.
“Hey, sorry about that, I’ll fix it…are you okay?” Kelly asked as she noticed that Sam was in a slight daze from all the strong smells he was experiencing. He quickly snapped out of it and smiled back to his cousin to reassure him that he was fine.
“Don’t worry Kelly…everyone has to use the bathroom, I’ll just wait a few minutes before I use it.” He hurried out of the room as Kelly looked a bit embarrassed by the whole thing. Thinking for a minute as she wondered if she really did embarrass herself in front of her cousin, she shrugged off the whole thing as she started spraying a lot of the air freshener into the bathroom, coughing from the magnificent stink that she had produced.
Back downstairs, Sam had found Briana in the kitchen and saw that there was no one else in the room when he made a comment about being in the bathroom.
“Jeez your sister sure knows how to take a dump…it reeks in that bathroom upstairs.” He said waving the air around him as Briana turned her sweet face around and started laughing at the idea.
“Yeah she does that a lot.” Briana said laughing.
“Really, she’s worse than you, I mean after what you did there with your mother earlier.” Sam asked, trying to bring the subject back to what Briana had done earlier. He had been trying to piece together what he knew about his two cousins and their smelly rear ends and so far today the picture had been pretty good to look at.
“I don’t know if she’s worse than me…but she’s very bad. You DO NOT want to walk into a bathroom after she’s done number two, that’s for sure. Our brothers are all the wiser not too and they can stink it up themselves, but I think she’s worse than the two of them combined…just don’t tell her I said that.” Briana and Sam laughed up the issue as he quickly changed the topic to something else to avoid dwelling on such an uncomfortable topic. True enough, nothing else had been mentioned about the whole thing throughout the remainder of that family get-together and with that Sam was only left to dwell on the memories of the event. He would look at the bathroom from that day forward just thinking about what Kelly had left in there and likewise would think about Briana and what she did with her mother too. His mind and its thoughts on his cousin’s farting and shitting would only continue to pervert itself now that he had the knowledge and experience. It was one thing to fantasize about the events taking place, but it was another when he had actual experience, of the power and stench of such things, it would drive him insane for the next few months as he awaited the next family function, Thanksgiving.


For Thanksgiving, Sam and his family traveled two states over to the house where Briana and Kelly lived, as their part of the family was hosting the Thanksgiving feast for that year. With such a big feast anticipated, Sam was eagerly awaiting to see if the issue of his two cousins breaking wind would come up again. As they greeted each other it appeared that Sam and his two cousins were still of good terms and there was no reason to doubt otherwise. And while Sam would converse with the others in his family and play around with the other cousins in their own way, he kept his eyes back at his two cousins, and just how marvelous they looked. Briana wore a grey sweatshirt that was a typical college student look, as she was a sophomore in college. She again wore a pair of black jeans that hugged her ass quite well. It wasn’t anything that was designed to make her curves stand out, but that wasn’t the kind of person she was anyway. Kelly wore a pair of pink sweatpants that was different than what Sam was used to seeing, but with her white T-shirt showcasing her still-growing breasts and the sweatpants hugging her still-growing ass, it made her look even more beautiful. Even with her glasses on she had the look of a sexy academic person and that only helped to enrage Sam’s fantasy even more. The fact that he remembered her massive dump a few months prior had helped things too.
Because of their travel, Sam’s family was going to at least stay the night at his cousin’s house, which gave him a little more time to work with what he had. The two-story house had several rooms that were converted so that other family members could stay there. What Sam was more interested in though was something a bit more devious, something that had entered his mind from the moment he entered that house, to head into bathroom and into Briana and Kelly’s bedroom itself to enter the “belly of the beast,” as he called it. He’d have to time it at specific parts of the evening, when the rest of the family was far enough away from the upstairs that even the two girls themselves would not be present.
Entering the bathroom was much easier; after all it was expected to get more usage during the evening. He entered the upstairs bathroom that was next to the girls’ rooms getting just what he expected, a clean bathroom. Walking in there was a sink with a mirror and a regular white toilet next to it. To the right of the toilet was a bathtub with a blue shower curtain hanging down so that you couldn’t see the inside of the bathtub, which also worked as a shower. In the bathroom they had plenty of air fresheners and candles around to make sure that the bathroom was looking immaculate. But the fact that there were several candles around the toilet and three cans of air freshener made him think about the reason for such items. He looked around for any sign that Briana or Kelly had been in that room but alas none were found. Clearly the girls did clean up after themselves and since dinner had not yet happen there was no reason for the bathroom to be used. He did himself use the bathroom just to give the impression that he was using the bathroom. One sign did clue him in on the bowels of his cousins and how big their wastes might be, the toilet sucked more of the water as it was flushed, giving off a louder flushing noise than on his own toilet back home. With a more powerful toilet that meant, to him anyway, that the dumps had to be more powerful.
As the smells from the Thanksgiving meal were starting to fill the house with about a half hour left before the meal would begin, Sam would begin his most dangerous endeavor, a trip into the bedroom of Briana and Kelly. He entered the room and looked around at the fixtures inside. The room was large enough to have two beds and two desks with wooden chairs, presumably for each girl. There was also two sets of drawers near the door. Immediately, he noticed the smell, it was a pleasant smell, something that smelled like an air freshener had been through the room recently with the scent of flowers, but with something else mixed in. His nose was able to detect a slight eggy smell in the midst; mixing in with the flowery smell so that the two together would smell fine, but separated and he would notice the difference. His heart was already pounding at the mere thought of the eggy smell in the room and where it originated from. Their room was decent in size for holding the two girls inside of it. He could tell which bed belonged to Briana and which one was Kelly’s. But it was the tall dresser that he was the most interested in. A perverted idea had entered Sam’s mind as he entered the room and it made him think of the possibilities. With his heart pounding fast he decided to make the fateful decision of opening the top drawer, which contained much of the lingerie of his two cousins.
Looking inside he started looking at the various pieces of underwear that were inside. He also saw the bras and saw that one was for a C cup pair of breasts and another for a D cup. He assumed that the former was Briana’s and the later Kelly’s. Briana was the older girl, but it had become clear in the past few months that Kelly was the bigger and sexier. Most of it was cotton panties in several colors and a few thongs themselves. He wonders which was whose, as Briana was the bigger person but Kelly contained what he figured was the bigger ass. He looked closely at the seat of a couple of those panties and saw a small skid mark in them. One was a pair of white cotton panties and the other purple, but both had skid marks on them. Pressing the skid mark up to his face he had hoped to smell some of the crap that may have remained on them but sadly the panties were already clean, the skid mark was simply what DIDN’T come out. He was enjoying this for a moment, trapped in a world where he was enjoying his cousin’s underwear. As he placed the underwear back inside he turned his back to get the quickest mood whiplash possible, the sight of Briana and Kelly with the door open, looking at Sam as he went through their underwear drawer. Awkward moment indeed.
“What are you doing in here Sam?” Kelly asked as she and her sister saw their cousin quickly slammed the drawer shut and started to make his way out of the room. Briana and Kelly were quick to get in the doorway and demand that Sam explained himself.
“Uhh….just looking.” Sam said in a wimpy voice as the two girls looked at each other and nodded.
“Wrong answer.” They both said in unison as Briana pushed Sam back in a way so that he fell on his back on top of her bed. With him lying down, Briana made a quick move around his body and sat her butt right on top of his stomach while Kelly grabbed the legs and held them in place as she sat down next to them.
“Now, let’s try this again Samuel…what were you doing, looking in the drawer…and at our underwear?” Said Kelly as the two girls looked at him.
“Um….not sure…I guess I wanted too….oh well I don’t have a good answer.” Said Sam as he tried his best to weasel himself out of this situation, but it was useless; there wasn’t much he could do. Sam was feeling something very odd about this whole situation, yet also very neat as well. The weight of Briana on his stomach was a little painful, but that fact that it was her butt sitting down on it made him feel a lot better. He could feel now the vast expanse of his cousin’s ass, and he saw Kelly’s big butt on the bed as well, but not on his actual body. They both saw something popping up in his pants and that’s when Briana got an idea.
“Sam…you’d better give us an answer…why were you there?” Asked Briana.
“I can’t give you one; I just wanted to see what your underwear looked like.” He said as the two girls looked at each other shocked. They couldn’t believe that one of their cousins would do such a thing, and especially one whom they liked. The relationship between Sam with Briana and Kelly were always nothing other than good, to see it go this way was not what Sam wanted.
“Well…now you’re going to feel what it’s like to be my underwear.” Briana said as she began grunting a little. The member in Sam’s pants started to get a little bigger as he felt the rumbling coming from Briana’s ass. Suddenly, she farted on his stomach.
BBBBBBBBPPPPPPPPPPHHHHHHHHHHHHAAAAAAARRRRRRRRRTTTTTTTTTTTTTTTTTTTT!!!!!!
The fart stretched out for nearly ten seconds and was a masterpiece if Briana had ever heard one before; it was a big fart by her standards. The bubbly fart created an effect on Sam’s stomach similar to someone pushing their lips against it and blowing on. The shaking actually impacted most of his body, but it was the smell of the fart that caught their attention. The smell of broccoli and cheese hung over in the air, indicative of the food that Briana had eaten earlier that day.
“Briana, oh my God that stinks!” Kelly was quick to get up from her seated position and move away from her sister. Briana laughed her ass off as she fanned some of her fetal fumes over in her sister’s direction. Kelly had her nose underneath her shirt as she started coughing a little from the pungent odor of Briana’s fart.
Meanwhile, Sam was taking back by the warm gas that was blowing around him, but he was in much better spirits than he would have otherwise, and that’s when Kelly noticed the boner in Sam’s pants. Briana turned her head toward Sam’s crouch, waving her long dark brown hair around before turning back to Sam and looking a little disgusted.
“Sam? Why do you have a boner?” Asked Briana as Kelly moved over toward a wall, the furthest away from leaving the room as she could be without smelling   the absolute worst of her sister’s farts.
“Um…cause I like the smell.” Sam finally spilled the beans of what made him go.
“You like the smell?” Asked Briana, astonished by such a claim.
“Yes I do…there I said it. I like the smell of a girl’s fart…you happy…I like the smell of your farts, you happy Briana…I like it, like it, like it.” He started yapping up a storm as he proclaimed once and for all the thing he really enjoyed, smelling farts, especially from girls.
“You like…smelling my farts?” Briana asked, trying to understand her cousin and his apparent delusion.
“Yes I do…I’m sorry Briana…Kelly…I know it’s weird and creepy and wrong and just not right, but smelling that fart just now really made me…like it.” Briana looked around the room for a moment, trying to process all that her cousin had just told her. He worried about what she would think next. She looked over at Kelly, who was at more of a loss of words than she was, not to mention the fact that Kelly still had her hand over face, trying to avoid the powerful smell of Briana’s fart, thankfully dying down.
“You seriously need to cut down on all that broccoli Briana…I can still smell it through my shirt.” Kelly continued to complain as she could still smell the gaseous aroma through the musky sweatiness underneath the front of her shirt. Even through the smell of her breasts, she could inhale what had just resided in Briana’s colon as if it were as strong as ever. The smell was dying off…but slowly.
After thinking it over for a minute and moving her jean-covered ass against his stomach a little more, letting a little more of the trapped up gas flow around his belly, she turned her head back toward Sam and gave him the cutest smile. Her smiles were a hallmark of her personality, the kind of smile that would come from an angel, the perfect smile that ensured that she was a divine person with no devious intent whatsoever, that kind of smile. Sam enjoyed seeing the smile and thought that he would get out of this one without much issue.
“Hey Sam…how about this. I do like you, and that fact that you were honest about your love for my…um farts was nice. I can’t say I’ve ever met anyone who liked that part, but whatever. I think I know of a way for you to be punished for your actions without having to tell the rest of the family, I mean you don’t want your mom to find out about this do ya?” Briana worked her way around what she was thinking about doing. Sam nodded his head, trying to breathe his best since the smell of Briana’s fart was still hanging over, and the fact that she was seated on his chest didn’t help any.
“Okay, so here’s the deal. You like the smell of farts, me and Kelly can fart…a lot. All it takes is the right amount of food and the two of us can go for all night. Feed us the right stuff, and this room will smell like rotten eggs for the entire night. Now since you like that, how about a fart contest, between me and my sister, and you’ll be the one judging us. Once we wind down after the meal is over, we will get to fart in your face and have you sniff it all up for the entire night….that will be your punishment. And if you do EVERYTHING we tell you to do and smell EVERYTHING we tell you to smell…we say that this thing never happened. Deal.” Briana said giggling to herself as she started to get a little aroused by the idea. Even though she was always a good girl at heart, every now and then this torture stuff had merit, even for her.
He looked over at Kelly and saw that she was no longer holding her nose underneath her shirt, but was now walking slowly over in Sam’s direction with her arms crossed across her chest. The smile on her face meant that she was too looking forward to Sam’s answer. With a bit of curiosity and worry, Sam nodded his head and agreed to the terms.
“That’s a good cousin…and don’t worry about us Sam, we’ll take care of ourselves. After this, we can go back to being regular cousins, just don’t try anything stupid…” Briana began talking, but that’s when there was a knock on the door, it was her mother.
“Come in.” Briana said as she quickly got off of Sam’s stomach and forced Sam’s body up so that he was seated on her bed. Briana and Sam sat there on the bed with Kelly standing there, all three looking innocent as was intended.
“Oh hi, that’s where you went Sam. I just wanted to let you know that the meal will be ready very soon, so we’ll be having grace downstairs in a few minutes…and oh God….oh God Briana that was bad…what did you eat earlier?” Briana and Kelly’s mother said as she pinched her nose. Even in its waning days, the power of Briana’s fart was still strong enough for her mother to notice it.
“Err…sorry about that, that broccoli from earlier had been tearing up my stomach.” Briana said with her trademark smile on her face.
“I could not be in this room earlier mom, Briana was stinking it up soooo bad, it smelled horrible!” Kelly said as playfully waved the air around.
“Like you have any room to talk.” Briana said waving the air back in her sister’s voice.
“You’re right about that, for a moment I thought it was one of yours Kelly…I hope you’re fine in there Sam, don’t want the girls gassing you out of there.” Their mother said back at Sam who nodded his head and mentioned that he was doing fine and was used to the smell.
“By the way…are they normally like this?”
“More than often yes…they keep it to themselves and don’t normally share it with guests, but when in the precense of the family, they can empty out the entire house. We had a Mexican dinner a few weeks ago when Briana was here for a holiday and I swear I could smell their gas everywhere. Kelly alone could empty the house and Briana…well she can pretty much empty the house and the surrounding area if she wanted. We had to keep the windows opened all night to let the gas from those two air out…”
“Mom?! That’s enough!” Briana insisted, as she gave the impression that she was being embarrassed. In truth, the story was only making Sam’s member grow, to hear more tales of his cousin’s gas, tonight was going to be glorious!
“Right then, we’ll be praying soon so head downstairs when you can.” Her mother said as she closed the door. Sam looked at both his cousins with thought of that recent story in his head.
“Is that true?”
“All of it…we had the WORST gas that night…it stunk all night in here.” Kelly said, now proud of her moment there, both girls were proud of what they had done a few weeks back.
“But not as much as it’s gonna stink tonight. You are going to regret that you ever said ‘you liked farts.” Briana said as she helped Sam up on his feet and walked with him out of her room and down the stairs. He watched as Briana went down the flight of stairs with her bubbly butt bouncing with each trip. Behind him, Kelly placed her hand on his shoulders and gave her a dirty look, but it was all an illusion.
“And if you think my sister’s fart smelled bad, just wait until you smell mine.” She said in a quiet voice as she went downstairs. He really couldn’t believe what was going to happen, his heart started pounding as he awaited the moment that the fart contest would begin. The question was: would he survive it?
Soon it was time for the feast to begin and the family gorged themselves on the traditional Thanksgiving food: turkey, stuffing, corn, green bean casserole and pie. Briana and Kelly both helped themselves to some of that food, but they didn’t eat nearly as much as their family had thought they would. That’s when the girls pulled out two large cans of barbeque baked beans from the cupboards and insisted that they were hungry for that. Briana went into the refrigerator and took out a couple of frozen meals of broccoli and cheese and found a head a cabbage in there as well. The family was quite perplexed by the food choices by the two girls.
“No, we’ll have some of that tomorrow, but we are hungry for some beans and broccoli and cabbage tonight…seriously.” Briana said as she shrugged her shoulders and began to pour the giant can of beans into an equally giant bowl.
“But won’t that food make you….um….” Briana’s father started before he was cut off by one of his sons.
“It’s gonna make em fart…just stay away from us tonight!” James said as Briana had a small smile on her face. She took opened up the cans and poured one large can each into a bowl and brought the other food to Kelly, who was seated at a nearby table. Both of their brothers shook their heads as they knew what that kind of food would do to them.
“Mom, can they seriously be eating that food, with all these guests around?” The son had asked as their mother yelled back at Briana, but only with a warning.
“You can eat that if you want…but do not gas out any of our guests or you will be in trouble…got that Briana?” She asked as Briana shook her head with another smile.
“You too Kelly…especially you. Got that?” She pointed over at Kelly, who gave her cutest innocent girl look possible before nodding her head in agreement. The two girls laughed as they brought the food over into the side room and started to dig in. Sam could only think about the power that food would have on his cousins. The other family members were talking about the food choices for a minute, with both parents warning of what it would do, but they were cautious to not talk about farting amongst the rest of the family. It was something that they did not share with outsiders, nothing beyond what was on a need-to-know basis, and that was: stay clear behind Briana and Kelly tonight!
A couple of hours had passed since dinner and people were around the house lounging around and relaxing. All around were groups of people doing various things, six people were around one table playing a card game, some of the younger kids were downstairs in the basement playing with toys and in the main living room Briana and Kelly were lounging on the couch as their two brothers were playing video games while seated on the floor in front of the couch. Sam remained seated at a chair adjacent to the couch. He had been following Briana and Kelly that evening, awaiting the moment that they would be ready to unload their gaseous exhaust at him. But he knew that these things needed time and that the gas was still collecting in the girls’ stomachs. They had eaten that day more food than they had probably eaten ever before, but they did it knowing what would happen. They finished their bowl of beans and ate their fill of broccoli and cabbage. On top of that, they had several helpings of turkey and all the regular fixings; they were loaded beyond belief with stomachs that had never been as full as they were now. Watching the two girls sit there as their brothers played their football video game just made Sam eager for the real show, but the anticipation was there, he could hear a grumbling noise from one of their stomachs every now and then, but nothing serious, even serious enough for the brothers to vacate.
The two brothers, James and Dillon (a ten-year old) were playing their video games for what seemed like 30 minutes in a room that was mostly quiet. Both girls were busy messing around with their phones when it happened, the boys were assaulted by a strong surge of silent and deadly gas. At first they thought that the smell was nothing, but slowly it grew in strength and about 20 seconds after it had first been released it became too much for the boys who both placed their noses underneath their shirts as they dropped their controllers and moved back to the two girls who were now laughing their asses off.
“Briana?!” Both boys said in unison as they started to become assaulted by the killer stink. It was an utterly putrid smell, one that burned the nostrils of anyone who was closest to it, one that could be felt all around the living room as the fart’s coverage reached further and further away from its source. The amount of sulfur that was evident in this fart was not to be underestimated as the warm, musky gas continued to grow around the living room. Its smell was something not to be underestimated to, in one word, the smell was unreal! It could described as a baby’s soiled diaper being caught on fire and allowed to burn there in that living room. It was a smell that made both brothers gag as they quickly ran off to another room, complaining of the sudden burning sensation they were feeling in their eyes. The fart had a fury to it that even surprised the girls. Sam had to put his nose underneath his shirt and breathe heavily the somewhat unfouled air as he wanted to be in a good condition to take in their farts. And that’s when he saw it; Briana was standing up off the couch, blowing the putrid wind back at her younger sister, the one who had cut the cheese: it was a Kelly Fart!
“Jesus Kelly that’s horrid…that was all her Sam!” Briana laughed as she continued to wave the air, using both of her hands as she tried to blow the thick, burning gas away from her, but she was no match and could tell that the fart’s smell affected her too. Sam too was finally forced away from his seat as he stood there, trying his best to hide his erection, but it was no match for him, the 18-year old’s SBD had a power over him.
“Exccccccuuuuuusssseeee me!” Kelly finally gave up her attempt to hide the fact that she had let loose that silent creeper into the air and began laughing as she felt the impacts of that silent fart still burning her underwear and her pants. It was a fart straight from the pits of hell, or Kelly’s bowels as it were and it was horrendous. Three minutes had passed after the SBD had been cut and Briana and Sam both agreed that they had to vacate the room as the fart continued to expand in its power. It was unclear how long the fart actually was, but Kelly felt that she was pushing on her anus for about the same amount of time it took until her brothers first noticed it. Kelly laughed a bit as both her sister and cousin left the room and rejoined her brothers in a nearby room. The brothers were relaying the story about what had happened in the room.
“Yeah, and what did you think was going to happen. But Kelly’s an adult now and she can make her own decisions. Luckily we don’t Briana here as much so or else it would be worse, but you know that doesn’t seem much better.” Her father said as Briana stood there with a smile on her face. She had heard the stories of what her sister had done during the past year while Briana was off at college. With the exception of holidays and breaks, Briana was now off at college and Kelly was the girl of the house, and her growing gassy prowess had been on full display in the past year. Briana was always bad as a farter, but it was becoming more evident that Kelly was competing at her level, if not surpassing it. At least this is what Sam got when the two parents talked about it with Briana and her two brothers.
“Yeah, you don’t want to be around when Kelly farts, they say that girls don’t stink when they fart, but she sure does…way worse than you Briana.” Dillon had commented on the past year or so at the household with Kelly as the oldest kid around.
“You don’t sleep in the same room as her, it’s not too bad, and I don’t know that I would call it the worst…I can clear out a house by myself.” Briana said giggling to herself as Sam had seated himself at a table, surrounded by Briana and Kelly’s parents, his own mother and another family member. It was then that they started to notice the rotten stench of Kelly’s fart; it had spread itself even further and was now entering the room. It wasn’t an overpowering smell, but enough to be at least noticeable. As if the timing wasn’t any better, Kelly had walked in there with her glasses on and a big smile on her face.
“Speaking of clearing out the house.” Their father said as a direct “take-that” at Kelly who stuck out her tongue and gave him the raspberries.
“Oh it hasn’t cleared out the house…though I wouldn’t walk into that room for a few minutes…that one really surprised me.” Kelly said giggling as she waved a little residual air that had hung around her butt.
“It doesn’t surprise me.” Said Dillon as he was paid back with his comments by a quick movement of Kelly’s butt against his back. He could feel a little extra heat as he quickly got up from his seat and screamed at the horror of his sister’s ass against his back.
“Keep that thing away from me…keep it away.” Dillon ran off as the others laughed some more. Sam was getting more aroused as he looked at the two cousins standing there, laughing away at the power that had been exerted from Kelly’s butt. He returned to the living room five minutes later and felt that the air still smelled of the burning gas that she had leaked out. He walked toward the couch and attempted to smell the cushion, but was ambushed when Kelly walked in and laughed at the still-clinging creation that was her fart.
“Ha…ha…ha….that thing had a lot of power…and if you thought that was bad, just wait until later, you won’t be able to sleep tonight, not with me and Briana farting up a storm. Oh boy are you in for it!” Laughed Kelly as Sam stood there with his hands in his pockets, trying to keep down his raging boner. Sure, it was his cousins and he knew how wrong this was, but the anticipation was killing him. Smelling the aftermath of Kelly’s SBD fart only made his anticipation grow, he really was in for it.
Another couple of hours had passed before it was getting time for bed. Neither Briana or Kelly had farted again and even with that it had taken a full half hour for Kelly’s previous SBD to completely fade away, and that was not news boding well for Sam since Kelly was becoming more and more full of gas, but to make matters worse, so was Briana. That’s when Briana and Kelly had asked if Sam could sleep with them in their room that night. It was and odd request, but one that got approval from the two girls and from Sam. Some of the adults weren’t sure if this was a good idea, but since all three kids were already adults themselves and their bond was good enough that Sam sleeping in their room was viewed as alright, there was little more objection. Sam just had to promise to sleep on the floor and not to do anything stupid, but there was one other concern the father had.
“Are you sure you want to…I mean it may stink in there.” The father’s warning gave Sam more to think about, the thought of the girls farting in their sleep. Sam nodded his head in agreement and added that if things got too bad he would move out and head for another room, where he had been slated to sleep in originally.
“Do you think that might happen, that I may have to leave?” Sam asked the girls’ father.
“Did you smell what Kelly had laid in there earlier? Both of them ate beans and on top of what we had here. We just want you to enjoy your time while you’re here Samuel, we don’t want you to be gassed out. It’s fine if you three want to sleep in the same room, as long as you’re not in bed with either of them. We just want to make sure you’ll survive, that’s all.” The father’s voice was reassuring, but disconcerting at the same time. In any case Sam agreed to the terms and he brought his blanket and pillow upstairs and opened the door to set up shop for where he would sleep that night. Another 15 minutes had passed as Sam waited for the other adults to get ready for bed themselves, along with the younger kids who were already asleep. James and Dillon walked past their sisters’ room one last time before agreeing that it was a mistake for Sam to stay with them that night.
“Oh I’ll be fine…I can handle it.” Sam reassured himself as the two younger brothers shook their heads.
“I don’t know….surviving one of Briana’s farts is hard enough, those things are killer! But to survive Kelly too…I know we don’t want to stay in there overnight, especially after they ate beans. There’s a reason we stay away from our sisters’ room, and it’s not because we are being nice to them….it’s because we value our oxygen. Good luck in there….” James said as the two boys walked down the hallway toward their own room.
“You’re gonna need it.” Said Dillon as Sam walked through the doorframe and entered the bedroom of Briana and Kelly. A couple of minute had passed before the star attractions of the show arrived themselves, dressed in a pair of pajamas that accentuated their curves even more. Briana and Kelly walked into the room and closed the door, locking it behind them.


“Okay Sam….no backing out of this now. The two of us are bursting with gas and you are going to smell it for us ALL NIGHT LONG! Do that or the deal’s off and we tell your mom how much of a pervert you are…got it?” Sam shook his head in agreement and couldn’t help but to take his eyes off of his cousins, they were looking stunning that evening. Briana wore a pair of dark blue cotton pajama pants that were being stretched along her long legs and up to her bodacious behind. Her legs looked even better than he had though they would look with her pants on. Her top piece also made her chest area look very nice. Sam had always admired the beauty of his oldest cousin, the 20-year old Briana, but in the past few years he had slowly gotten used to her younger, 18-year old sister. Kelly had keep her pink sweatpants on as they were that evening, trapping in the retched gas that still stunk of her one SBD. Her top piece was of a matching pink color with buttons running down the center. The top two buttons were on to show that Kelly had grown more at the top of her chest too. In fact, they looked like D cups now, bursting out of the top piece with a piece of deep cleavage to show. Despite the fact that her glasses and ponytail made her look a bit homely, she was more of a stunner than her sister in almost all regards.
“Okay, so who’s first then?” Asked Sam as the two girls looked at each other for a moment before Kelly spoke up.
“I’ll let my big sis go, I still got gas bubbling up within me…she can let loose on you while I build this up.” Kelly said as Briana began smiling, rubbing her stomach with the gas that was also building within her. She then instructed for Sam to lie down on her bed, the bigger of the two beds in the room. There Sam laid his body facing up toward the ceiling, extended across the bed with his feet positioned near Briana’s pillows. Briana took one of her white pillows and placed it where Sam was going to be putting his head; she wanted Sam’s head to be well positioned as she turned around the pointed her butt toward Sam’s head. This was the moment he was waiting for.
He watched as the pajama covered behind of Briana came crashing down on his face. His vision had been that of the room around him, a typically-lit teenage girl’s bedroom but that vision was coming down as the 20-year old girl was lowering her ass onto his face. He could see the mounds of juicy girl butt flesh that was his own cousin’s. Every instinct in his mind knew that there was something disturbing in all of this, that this whole thing wasn’t right, but with consent given all around, he allowed it to continue. After what seemed like an eternity but was only a couple of seconds he began to feel the asscheeks around his face. Briana’s butt was incredibly huge, but big enough that Sam’s face was immersed in it. It felt like two volleyballs being brought down onto each cheek of his face. He felt the warm cotton fabric of the pajamas as he felt the strong, reaffirming buttocks behind them. Finally, his nose got to feel the crease in her pajamas right where the butt crack was. After those two seconds, Briana’s ass was firmly against Sam’s face. He could see nothing but the darkness created by the 20-year old’s body on top of him and feel nothing with his nose but the small void that was created with the distance of his ass. She moved her butt around him for a moment, just messing around with his face before she resumed the butt’s position. Sam now thought about his quest to find out about his cousin’s farts, he was about to regret it.
“Oh God Briana…that is so sweet…I got to take a picture of that!” Kelly squealed as she took out her phone and took a picture of the sight. It was a glorious site, Sam’s body lying down on Briana’s bed as she sat upright on top of his face. The pillow made it so that her ass would also rest on the part of the pillow that Sam’s head wasn’t on. But now came the fireworks.
