PART 1
“Well, good evening, Peter! How was your day?”
“Quite alright, thanks for asking.” Peter didn’t even look up from his laptop as Catherine and Helen came through the front door. “How was yours?”
“Oh, just fine.” Catherine responded, stretching as Helen shut the door behind them.
“Have you found what you need to get out of this town?”
“Mmmm, not sure. Think we’ll have to…sit on it for a little longer.” As she spoke, Catherine absentmindedly rubbed her hands along her ample rear, casually feeling up her own booty.
It had become a running joke by this point. Peter would ask as if he wanted them to leave, blaming them for all the “damage” they had been doing to his lungs. Catherine and Helen would always reply that they’d have to “sit on it.” It was admittedly silly, and Peter wasn’t even sure if that was a common expression to use, but the details didn’t matter. What mattered was that two superheroines with super-enhanced booties and super-intoxicating farts were living with him.
A little over a month after their initial encounter, they had settled into their own little rhythm of life. Peter still had a shop to run, of course, so that was most of his day. Helen and Catherine, meanwhile, would go out on their secret mission, scouting out the town and looking for information about the archives they were trying to study. Sometimes they returned late, long past sundown. Sometimes they returned for dinner and some rest, before they had to head back out for the night, leaving Peter to wonder whether all superheroes had some kind of reduced need for sleep as part of the package. And sometimes, out of the blue, when they returned quite early in the evening, the three of them would retire to his room and partake in “training sessions” as Helen worked to enhance and perfect her newfound gassy superpowers. Or at least, that’s what they insisted they were doing.
On this particular day, they had returned at an awkward hour, and Peter wasn’t sure which way the evening would go. Though he certainly hoped tonight would be a “training session” kind of night.
“Mmmnnnhh…”
Peter finally looked up, his nose wrinkling reflexively from the sudden stench it was detecting. Soft, green wisps of gas emanated from behind Helen, betraying her completely silent release. As he watched the two of them snicker, he saw Catherine add her brown fumes to the mix with a seductive squinting expression frozen on her face, still without a single sound. He sighed. They had been back for all of about ten seconds and they were already unloading their super-stink into the apartment. It was time to kiss fresh air goodbye, at least until the morning. He shut his laptop, feeling an erection emerging below it already as their gas began creeping into his lungs.
“So, uh…” Peter tried not to sound too eager as he inhaled their little sample. “So, are you two done for the night? Or, or are you heading back out later?”
Catherine grinned, well aware of what he was getting at. She stretched again, more dramatically this time, making sure to present her magnificent physique in all its glory. Peter tried to keep his eyes from wandering, but his hunger got the best of him, tracing his gaze along her figure and its curves in her tight brown getup. He couldn’t help it, and he firmly believed that neither could anyone else. Catherine’s glorious booty was utterly irresistible, with its subtle jiggles and firm texture, just the right amount of fat and muscle, and of course, its powerful size that practically gave it a gravitational pull. Already, his mind was replaying the numerous gaseous “training sessions” they had indulged in for the past month, and knowing that this stunning woman had a gut packed full of gas — as she pretty much always did — was only adding to his growing wanton lust.
“Hfff. I don’t know.” She turned back to Helen, who in return gave her a knowing look. Peter picked up on some sort of unspoken agreement between them, as if they had discussed something while they were out of the house. “I’m pretty beat. Helen?”
“Mmm. Me too. I think I might turn in early tonight, actually.”
“You don’t want dinner? Have you eaten already?” Peter asked gingerly, still feeling like he was out of the loop. He set his laptop down on the table in front of him.
“I think I’ll be okay, thanks.” Helen yawned. “I’ll be in our room if you need me. Cath?”
“Yeah, I’ll be right up.” As Helen passed her to reach their guest room, Catherine gave her booty a ringing smack. Helen glanced back, giving her a mockingly scandalized look, before disappearing into the hallway.
Peter watched with growing interest as Catherine made a big show of doffing her jacket that she liked to sometimes wear over her superhero outfit. She casually dropped it onto the floor, and as she slowly bent over to pick it back up, it was one of those frequent moments where Peter honestly couldn’t tell if she was using her powers to enhance her booty or if that was just how good it looked from certain angles. If her big butt looked delicious before, it was positively mouthwatering now. She had, of course, chosen to bend down in such a way that her booty was being presented to Peter, whose seat on the couch gave him a perfect view. It was so hypnotic that it took Peter several seconds to notice the cloud of brown slowly expanding around her.
…ssssssssssffffrrssssrrRRRRRRRrrrrrrRSRSHSHHHHHHhhhhh…
As much as she loved to make Peter drool over her booty, here was another trick that she loved – her notorious super-long SBDs. For some reason, she found it hysterical to casually release a truly super-powered fart. But rather than dropping a devastating bomb in a sudden blast, she liked to slowly eke out a vicious and seemingly-unending stream of brown gas from her noxious hole, often lasting more than a minute. In fact, if he remembered correctly, she pulled this exact trick on him the very first night they met. It was probably the very first fart she released in his presence, too.
This particular fart had started in complete silence, or maybe Peter just hadn’t noticed it fast enough. But about ten seconds in, he detected a very low, bassy rumble, almost like it was a tuba that had somehow learned to play notes at the lowest range of human hearing. He watched as Catherine reached back with one hand, teasing apart her two globular cheeks to aid in her release. As she did so, the sound began to increase in volume for a brief few seconds before Catherine fought it back down, slowing her output again to weaken it.
…ffffrrrgrrrggrggrrrmmmmmmmssssss…
A classic Catherine delivery. Just as Peter thought it might have been tapering off, he could hear its grumble pick up again. She was demonstrating a truly masterful level of control over her gas and her booty. The cloud around her was now dispersing, and the first inklings of stench were finally making their way into Peter’s nostrils. The little teaser from earlier did not prepare him enough; even though they had farted in front of him countless times thus far, the first blast of the night was always the hardest to adjust to. Peter stifled a cough as he continued to bask in the sensory experience — the bassy sound wavering just in and out of the audible range, the smell of rotting sewage slowly but steadily increasing in intensity, and the sight of a brown mist dispersing throughout the room, its color darkest at its epicenter right between Catherine’s stunning cheeks.
After what felt like an eternity, Catherine rose from her bent-over position, the jacket still on the floor and completely forgotten by the two of them. She turned her head to meet Peter’s gaze.
“Oops. That just slipped out.”
Catherine was able to hold her composure for exactly one second before she sputtered into cackling laughter at how absurd that comment was. Then she bounded down the hall to their guest room, not even glancing back at Peter to see his reaction.
As he heard the door shut, Peter found himself dazed, surrounded in a light mist of foul brown gas. As impressive as it was, he knew that fart was practically nothing compared to the Booty Bomber’s true prowess. Still, the odor and the sight of her beautiful butt wobbling from the sheer force of the gas bursting through it was enough. Peter sighed, his hands already finding their way to his pants as he took in steady lungfuls of Catherine’s gift.
~~~~~~~~~~~~~~~~~~
Catherine held back a snicker as she bounded down the hall and shut the door to the guest room behind her, thoroughly pleased with how well she was able to turn the living room into a hotbox with a single fart.
“Ahh, that should keep him busy for a bit.” She gave her sizable booty a nice, well-earned smack, feeling it undulate lightly in response to her knowing touch.
Helen smirked. “I thought the whole point was to keep him wanting? What gives?”
“Sorry. Couldn’t resist.” Catherine threw herself onto the bed, limp. “Ugh! I wasn’t kidding, though. I’m beat!”
Helen looked down at her face-down on the bed as she casually threw some of her belongings onto the table in the corner. She liked to travel light, as did any superhero – but some things you just had to keep on hand. “Couldn’t resist what? Fogging up the poor living room the second you walked in? Stinging that poor boy’s eyes with your toxic brown gas?” Her smirk grew. “The mark of a true super is restraint, you know.”
“Oh, shut up,” Catherine retorted into the mattress, still not picking up her head off its surface. “You started it!”
Helen put a hand to her chest. “Me? Fart in this house? Never! How dare you accuse me of such a vile thing!” She turned her head up in mock disgust, still fighting a smile.
“Is that so? Then what was that vicious stream of green gas that floated out of your massive booty?” She, too, was now on the verge of laughing. “That nasty stank that I smelled? Do you just have a green aura floating around you? Does your thick butt just purr sometimes?”
Helen retaliated. “I don’t know what you’re talking about, I didn’t hear a single thing! And the smell, excuse me, that must have been you and your gargantuan butt! Look at that thing, it’s like a loaded cannon!”
Catherine paused for a brief moment as she tightened her stomach ever so slightly. While maintaining eye contact with Helen, she began to eke out another toxic fart, more brown gas spilling out of the crevice between her powerful glutes. As the foul, visible wind blowing past her cheeks continued on and on, her smirk grew and grew, still directly facing Helen, who was watching her incredulously.
“I have no idea what you’re on about, Helen,” she said as calmly as she could, the cloud still growing and expanding right above her. “This is not a fart.”
“That’s not a fart?” Helen folded her arms.
“Nope. This is.”
…mmmrrmrrrrffrrrbrrrbBBBRBRBRRRRBBBRPRPRFFRRFRR–
Technically, it was still the same fart. Catherine effortlessly tightened her stomach even further, dialing up the rate of release on her signature brown gas. She reached back, pulling one of her cheeks aside, the skintight suit’s material groaning slightly. With more power behind her fart, she pushed it up into the audible range, and she and Helen began savoring the bassy rumble that spewed more fumes into the innocent air.
–RRRRFFRRRRMMMPRRRRRRRPPPPRRPRPRPPPPPTTT
As the fart reached what Catherine considered a worthwhile stopping point (which, frankly, was entirely arbitrary), she released her own butt from her grip. Though her eyes were closed as she finished off the impressive blast, she knew Helen was getting a front-row view of the cloud of brown steadily dispersing through the room, no corner of it safe from the intoxicating odor of some meat that had gone horribly wrong. She felt the motion of her booty undulate slightly again, surely agitating the gas above her with soft waves of wind, helping it disperse even further.
She rolled over on her back, hoping to marvel in her creation. As she opened her eyes, however, she was met with only green and black.
“MmmpH!”
Helen had taken her moment of opportunity while Catherine was distracted by closing off her gargantuan fart. It was moments like this that reminded her that Helen had the advantage of experience, deftly seizing the chance to move without being detected. In this case, Catherine had left herself wide open to a full-on face-sitting from the world’s most suffocating booty…after her own, of course.
“What did I teach you, Cath?” She could already hear the smile in Helen’s voice. “Always stay on your guard, no matter what.”
Catherine didn’t even respond. She had no complaints about being buried under Helen’s cushy booty, and definitely had no complaints about what she was about to do to her airways. But even if she wanted to protest, she knew she couldn’t, because of just how voluptuous Helen’s rear was. It was different from trying to talk into the mattress earlier — there was absolutely no room to even open her jaw. She was “stuck” breathing through her nose, by default.
Helen laughed above her, the sound muffled by her luscious booty. “Oh, let’s drop the charades already. Go ahead and breathe deep for me.”
BBBRBRRRRRRrrrrrrmmmmmffffffff…
Catherine happily obliged. A thunderous blast rocketed out of Helen to kickstart her release, punching Catherine right between the nose and mouth before softening up into a lingering murmur. She almost unconsciously began to move her hands to grip Helen’s cheeks, feeling just how soft and plump they were as her fingers sunk in. She played with the flesh as she filled her lungs again and again with Helen’s flowing green fart. A thick smell of carbs hinted at her recent cheat day, covering up the more familiar tinge of rotten vegetable stink.
As the release slowly drifted into silence, Catherine could feel Helen’s butthole open up. Her elastic powers were not going to waste as she stretched out her anal ring by a tiny amount, allowing just a bit more vicious exhaust to blast out of her every second. Catherine could feel the fart quickening, and she knew that her lungs wouldn’t be able to keep up for long — the gas would begin to leak out of Helen’s impossibly thick butt-mask over her face and join her earlier release of brown venom. Nonetheless, she continued taking deep breaths, eager to fill herself up as much as possible with Helen’s green poison.
…sffrrssssSRRRRRRRMMMMMMMMBMRMRMBRRBBBBBBRRRRRRR–
As the gas continued to flow, rushing right past Catherine’s face, the tone of its sound began to pick up into a trembling bass note, as if a particularly foul tuba was playing directly onto her head. She could feel Helen’s joyous laughter get gradually drowned out by her tremendous fart, until all she could hear was brass.
–RRRRRMMMMmmmmmMBBBPPPRRRRRRRFFFFFFfffffsssssshhhhh…
Catherine could tell Helen was just flexing at this point — both figuratively and literally. Further taking advantage of her original superpowers, Helen was toying with the circumference of her gaseous exit, having quite a bit of fun by modulating the sound of the flowing green gas as it blew through her booty. Now, she was turning the dial back to silence, the stench still ever-growing as always. Several seconds after the sound had died down, Catherine could still feel the hot air blowing into her face at point-blank range as Helen continued her onslaught of flatulence.
The now-SBD finally hissed out and died down, though of course they both knew Helen was far from done. Still, Catherine thought, she needed to pace herself if she wanted to savor Helen’s gas. She tapped twice on Helen’s engulfing booty, their agreed-upon symbol for a breath of slightly-less-tainted air.
“Uff, that was a good one.” Helen rose up a little, leaning forward to free Catherine’s nose and mouth from the mounds of flesh covering them. “What do you think?”
“You know…” Catherine tilted her head, taking note of how the visibility in the room was just a tiny bit worse than before she had gone under. “As much as I love taking in your gas at point-blank range, I must say, your booty looks scrumptious from this angle.”
“Yeah?” Helen gave her cheeks a side-to-side wiggle in response. “Ooh, do tell me more.”
“I’m just being honest here, Helen.” Catherine reached up with both hands, kneading the doughy flesh heaving right above her. “Mmmm, look at all that booty. Being pinned under it just doesn’t provide the same view, you know? I love the way it jiggles, it’s quite the spectacle from down here.”
Helen bit her lip and casually began exerting her powers to expand her butt in size. “Ooh, yes, take it all in, sweetie. Take it all in. And while you’re at it…”
ffffffFFFFRRRRRRRRRAAAAOOUOOUUUUOUUUOUUMMMmmmMMMmmmMMMmm–
Without warning, Helen gunned the engine and began blasting another behemoth fart, this time with noticeably more force; Catherine presumed it was the added size, putting more booty flesh between Helen’s erupting hole and the outside air. The bassy expulsion struck Catherine right in the face again, raging on and on as she automatically began breathing deeper.
The gas blowing into her face made it difficult to keep her eyes open, but the view above her was stunning enough that she fought back tears to witness it. If she thought her booty had looked great from this close right below it, then it looked ten times better with gas spewing out of it with reckless abandon. With every second of bass blowing out of Helen’s backside, the cheeks on either side wobbled as if they were continuously being spanked gently. Each rolling wave of flesh brought a thick green mist, engaging in some sort of rhythm as Helen’s fart seemed to take on a life of its own. In and out, in and out, in and out. It was like getting one-two punched by the air itself, several times a second.
–MmmmMMmMrrrRRRrrrRRRoooOOOouuuUUUFffffFFFSSSSSSSssss–
Catherine, almost as if possessed by an invisible force, worked her hands through Helen’s massive buttocks as best as she could, spreading them just a bit wider to help ease the gas out through. Her booty had definitely been made larger, as she could feel her hands and even her arms straining to find its entire circumference. The spreading motions she made with her hands allowed Helen’s raging fart to settle into a pseudo-silence, still violently blowing away a torrent of foul, starchy wind but without the cheek-ripping noises from moments before.
“Ooohh, yes…Savor it, savor my booty and my unparalleled gas!” Helen moaned in symphony with her release.
“Unparalleled?” Catherine managed to choke out against the perpetual fog blasting into her face. “I would like to challenge that!”
—sssssSSSRRRRRPPPT
Helen cut off her release quite abruptly, catching Catherine mid-sniff. As Catherine blinked away the green haze swirling around her head and tried to get her bearings, her focus finally away from Helen’s massive rear, she could feel Helen rolling off of her. Regaining her composure, she picked up her upper half and found Helen lying down adjacent to her, a decidedly smug grin on her face.
“Well then, Booty Bomber.” Helen shifted her back and shoulders slightly to allow her hindquarters to shrink back to their still-impressive standard size. “Go ahead. Present your challenge.”
“With pleasure!” Catherine didn’t need to be told twice. She practically leapt into a sitting position over Helen, her arms on either side of Helen’s hips and her own booty hovering dangeorusly over her face. “Last chance to get some fresh air!”
Helen laughed in reply. “Fresh? Take a look around you, and tell me that there’s any fresh air left in this room!”
Catherine didn’t need to look around to know that Helen’s gas had established its presence, filling the entire space from corner to corner with a hazy green. And she sure didn’t need to take another breath to know that every lungful of air was going to be tainted with the stench of heavy carbs that had been digested and processed in the superpowered fart factory that was Helen’s insides.
Instead, she giggled back at Helen. “Well, say goodbye to green, say hello to brown!”
…ssssssSSSSSSSSSSHHHHHHHHH—
She didn’t give Helen a chance at another retort as she loosened the stopper, allowing a rolling wave of the promised brown fumes to blow right into Helen’s face. She couldn’t help but moan at the pleasure of such a powerful pressure blowing out of her backside, and savored the sound of silence rushing behind her — the sound that, much like with Helen, telegraphed an absolutely inhuman volume of gas passing through a too-narrow space every second. Her hands caressed the back of her own neck as she stretched, partly due to the pleasurable sensation flooding through her and partly to flex her stomach and blow out even more gas.
Helen, however, was clearly unfazed. “Is that all you’ve got?”
Catherine, taken slightly aback by her audacity, decided to respond with action rather than words. With one hand reaching backwards to rub one massive cheek of her booty, she gave a firmer push onto her gassy gut.
—SHSSRRRRRRRRRRBBRBBRBBBBRBRBRRRRR—
At the same time, recalling Helen’s exploits with her powers, Catherine harnessed her own to expand the size of her booty, feeling her progress with her hand. She loved to feel the fabric of her super-suit straining to match her growth; obviously, it was custom-designed so that it had plenty of stretch to it, but feeling it try to keep up under her palm was always a nice detail. As she did so, a powerful bass tone took over, the new size of her cheeks clearly presenting enough of an obstacle for the stream of fart gas that it could no longer be “silent.”
“Mmh, okay, Cath, that’s getting a little too much. Dial it back a size or two?”
–RBRBRRRRBRBRBRBRRBRRRBBBBBRRRMMMMMMMMMRMRFRFRRFFRRRRR—
“Mmmmm, sorry, I didn’t catch that, come again?”
Of course, Catherine could hear her plenty well, but she chose to pretend not to. Heeding no such request from her partner, Catherine instead kept her buttocks expanded, now large enough to barely fit on the width of the bed. Satisfied with her feat, she bore down again, trying her best to drown out Helen’s voice with her overwhelming tuba tone. Looking around, she still wasn’t satisfied with the green-to-brown proportions of polluted air left in the room. Helen’s headstart still tinted her vision with enough green. Not that it particularly mattered, admittedly — they were having plenty of fun as it was.
“I said, I think that’s enough!”
“Hah, says who?”
–RRRRRRRRFFFFRFRFRRFRrrrrrrrmmMMPPPpppPPRPppprrrRRT
What followed was a dramatic twisting of tone in her rumbling bassy fart, as she was suddenly subjected to a forceful repositioning. In a flash, Helen extended her lower legs upwards, striking with deft precision to corner Catherine’s head right between them. Then with a dextrous readjustment of her proportions, Helen grappled Catherine’s face to put it closer to her eager booty. Before Catherine even knew what happened, she found herself in a bizarre 69-esque position, where she was still sitting on Helen but Helen in return had clamped her head between Helen’s thighs.
PRRRRRRMRMRRRRrrrrrggrrgrrRRRMMMMMMPPPT
The surprise attack had cut off Catherine’s release, and Helen took her counterattack. Thankfully, she cut herself off after a few seconds, enough to make her point. Then, stretching her body again, Helen loosened herself from under Catherine’s titanic booty, now with just her legs wrapped around Catherine’s face.
“Oh come on! I wasn’t done. Get back down there,” Catherine said, pawing at Helen’s leglock.
“Hah, sorry, just had to put you in your place for that.” Helen released her. “Still, as much as I do find your booty seductive, I think I have my preferences when it comes to size.”
“Oh, what, you just can’t handle me with that big a booty, huh?”
“Not necessarily, just…” Helen trailed off as Catherine re-established her position on top, her rear back to its usual dimensions. “You know. Too big and it takes away from the…experience.”
“Oh?” Catherine was intrigued. She held back the wall of gas building at her rear exit, squirming a little at how lively it was getting. It was always an erotic feeling for her, but she sensed an intriguing conversation was imminent.
“You know…Too big and it just looks off? I think I prefer it just the right kind of ‘big.'”
“Uh huh…”
“Trust me, I spent years working this kind of thing out when I was younger. I mean, if you have an elastic body, what form do you choose, right?” Helen lovingly caressed Catherine’s buttocks as she reminisced about days past. “I decided to go modest, very slim, especially since that’s what was ‘in’ back in the day. But trends have changed! Now, a big, wide, heaving booty is very popular. And I am in full agreement,” she added, playfully spanking Catherine.
“Mmm.” Catherine gently rocked her hips for a light tease. “Oh, I am with you there. But how big is too– oh, hang on, pardon me…”
Catherine smirked and casually began another fart to interrupt herself.
ssssSSSRRRRMMBRRBRRMMMmmmMRRRRrrrrrRRRRRR–
The room’s fog was beginning to turn more brown than green as Catherine caught up to Helen, but with the conversation pointing somewhere interesting that they hadn’t explored before, Catherine hardly paid it much mind. The fact that Helen had a big booty kink was hardly a “revelation” given their recent history, but nonetheless it was worth exploring further. As Catherine eased into her steady release of fumes, Helen half-sighed, half-moaned.
“Mmmmm…”
“So where were we…?”
“Mm. Right, size. Butt size. How about you start growing that thing with your powers, and I’ll let you know when I think it’s at its best, yeah?”
–RRRrrrrrrmmmmrfrffrfrrfrfffffrrrsssssSSSSSS–
Catherine remained silent as she obliged, curious to see where this was going. She steadily expanded her booty outward, feeling it grow heftier. She had barely started when Helen gave the signal.
“Ooh, yeah, right there.”
Catherine stopped, but wasn’t happy about it. At just about the size of basketballs, with her hips and thighs bulking up commensurately, she felt she could get away with much bigger. “Really? That’s all you want out of me!? I know men that would die for a chance to see it grow a few sizes past this!”
“I’m sorry, Cath, I just…it’s hard to admit these things to yourself, especially at this age,” Helen said slowly, between shameless sniffs of the still-steady stream of flatulence into her face.
Catherine nodded knowingly before realizing Helen couldn’t see her head move. Before she could open her mouth, however, her attention was drawn towards the door, which swung open. She cut her raging fart off prematurely…by her standards, anyway.
Peter stood at the doorway, faintly blushing. A noticeable wall of brown and green gas wafted into the corridor behind him. “I thought you said you–“
“Oh, please.” Catherine interrupted, not even bothering to change her posture over Helen. “You didn’t really believe I was going to turn in early, did you? Not while I’m still full of a day’s worth of gas?”
“Oh, Peter, glad you decided to stop by,” Helen said from underneath her. “Can we have your opinion on something? No, scratch that. A couple of things.”
Catherine watched coyly as Peter came a few steps closer. He was still too shy to ever directly ask for farts in his face, and anyways, that wasn’t how they did things. This skirting around and teasing was much more fun.
“Oh?”
“Yes, Peter. See, Helen and I have are having some trouble deciding what size our big ol’ booties should be. You know, because we are both able to change its size at will?”
“Uh huh…”
“Well, I’m going to need you take a good look at this right here.” Catherine finally rose off of Helen’s face and turned around, such a simple gesture that she somehow made look sexy with a faint bend at the knees. The way her rotund backside came into view was like a planet rotating in orbit — or, rather, two planets, Peter supposed: it was such a stunning sight that he found it impossible to look away.
“Helen is willing to come out and say that this is the ideal size for my butt. I respectfully disagree. You’re our tiebreaker.” Catherine backed up slowly, bending at the waist to increase her rear’s already stunning magnetic pull. “What’s your call?”
Peter swallowed back some drool. Catherine’s explosive backside was mere inches away from his face, radiating warm residual stench from the skintight fabric encasing it. He had to actively resist the urge to push his face right into those soft yet supple cheeks and take a deep breath.
“Here, how about this.” An impatient Catherine withdrew herself to a smaller physique. “I’m just going to mold my body slowly, gradually increasing my size back here. You tell me ‘stop’ when you think I’ve hit an ideal size.”
Out of the corner of his eye, Peter noticed Helen eyeing Catherine with a modicum of suspicion, wondering what she was playing at.
“Ready?”
“Uh, I guess?” Admittedly, Peter was finding himself in a bit of an odd scenario. But any excuse to gawk at big booty was one he was willing to agree to. He brought himself down to his knees for a better viewing angle, which earned a quick stifled giggle of approval from Catherine.
Without another word, Catherine bent further down with one hand on her knee, pushing the superb physique of her stunning cheeks even further outward. With her other hand, she felt herself up, rubbing small circles on one side of her juicy butt. Peter loved watching the way it gave way under her firm hand, then spring right back into shape like jello. He traced the subtle waves of flesh rippling across the surface of her brown and gold super-suit, and his mind briefly wandered back to all their past facesitting sessions, where he was afforded more than his share of intimacy with Catherine’s unbelievably erotic backside.
“Just tell me when.”
For several seconds, the only sound in the room was the faint sound of fabric stretching as Catherine’s suit began reforming over her body to fit its changing dimensions. Peter felt Helen’s eyes on him, monitoring with curiosity, but the vast majority of his attention was directed right in front of him.
At its current state, Catherine’s irresistible rear was mere inches away from engulfing Peter’s face, and it took nearly all his willpower not to dive forward and close the gap. The sulfuric stink that emanating from her volatile booty was immensely alluring, even though she wasn’t even actively farting. He knew that she was holding back a flood of gas, and if he asked for it, or even just if she felt like it, she could release gallons and gallons’ worth of stupefying fart gas into his face, right now. Distracted, he began replaying the countless bassy, brassy sounds that this butt could make for his pleasure, like a personal tuba concert…
“Still going?” Helen’s incredulous comment snapped him out of his fantasies. Oh, right. He was supposed to be doing something.
“You really like ’em big, huh?” Catherine said, laughing. She was partly glad she was right, and partly surprised at just how much Peter was turned on by her huge butt. She tried to wiggle her hips as an added bonus, which was clearly somewhat difficult at the current massive size of her buttocks, easily larger than Peter’s head on each globular cheek. When she leaned into it, Peter got a first-row seat to a veritable earthquake of booty flesh, all of its juicy glory quivering and rippling to hypnotize him.
Another few seconds of expansion later, Peter’s entire field of vision was blocked out by a skintight suit struggling to cover all of Catherine’s glorious booty. Helen was no longer visible in his periphery, but he could hear her chortling. At this point, the original question was moot: he couldn’t really get a sense of Catherine’s full figure, so it was impossible to discern whether this was an enticing physique or not. But frankly, it didn’t matter. Now Peter’s mind was on something else, which Catherine verbalized just as he was thinking it.
“I see what you’re doing here, Peter.” Catherine stopped the steady expansion that was centered on her buttocks, leaving maybe an inch or two between its surface and Peter’s head. “If you don’t say something in the next few seconds, my butt will be mashing right in your face. And that’s what you want. Right?”
Peter remained silent.
“Ugh, Peter, you’re such a booty-crazed man, what am I going to do with you?” Catherine chuckled, which Helen joined in on. As Catherine turned around to face her, she nearly smacked the wind out of Peter as her prominent hindquarters swung around. Now that his eyes could actually focus on her body, rather than being engulfed by brown, he was able to drink in the way her full form dripped with sexual allure. This was definitely the most booty she had ever packed onto herself using her powers, and Peter was loving every inch of it. Catherine playfully caressed her backside, only accentuating its overwhelming gravitational pull.
“Are you taking suggestions?” Peter joked.
That earned another laugh from Catherine and Helen. “Oh, I think I can wager a guess,” Helen said, waggling her fingers. “Come on up to the bed. I think we can make something work.”
“Just want it for the record, by the way: Peter agrees with me.”
“Oh hush.” Helen lightly smacked Catherine on the back of the head. “Not everything’s a contest. And preference is preference.”
Peter, meanwhile, tried not to seem too eager as he lay face-up on the bed, even though all three of them were well aware of his desires at this point. Catherine’s thick buttocks came into view from one side, while Helen’s appeared from the other. He basked in their aura, four scrumptious cheeks’ worth of booty beckoning to him, surrounded by a light mist of fetid gas that tickled his nostrils in just the right ways.
“Just saying.”
“Actually,” Helen was saying, “he never did. You led him into an answer you wanted.”
Catherine folded her arms as she wiggled herself into position, her wide hips sending ripples through the bed. “Whatever. As long as I know how to make Peter happy, I’m happy. Right, Peter?”
“Uh ye–MMFHhh…”
Catherine snickered. “That never gets old. Cutting off your sentence by cutting off your air supply.”
“Oi,” Helen nudged her with a gentle backwards motion from her hips. “Leave some room for me. I’ve still got farts to let out.”
“Be patient!” Catherine said with a false air of indignance.
Underneath her, Peter was quivering with anticipation. Catherine had aimed herself perfectly, with her rectal opening squarely placed on the bridge of his nose. Each deep, hungry inhale he took brought in waves of ungodly stench, already beginning to poison his mind so he could think about nothing else but their divine gas. It was incredible how much stink she could offer him without even beginning to fart into his face.
Catherine allowed herself to savor the moment, shifting her weight to drive her enhanced backside deeper into Peter’s face before beginning her first facial gas blast of the day.
bbbbbbbBBRBRRRFRRRRRRFFFFRRRGRgrgggrGGRRRRRRRLL–
Her booty truly never disappointed. A rolling wave of heat unfurled itself out of her bottom, beginning with a feather-light rumble and quickly crescendoing to a full-on bassy tuba roar. Peter was immediately met with a gale-force of stench, and had he not been pinned down under several pounds of superbly sculpted butt, he would have surely been blown away.
–GRRRGGGGGRRRRRMMBBRBBRRSSSRMMMMMRRBBSHRRRS–
Peter’s trained nose was taking in as much of the gas as possible, maximizing every breath under Catherine’s relentless booty bombing. But a pair of lungs could only fit so much. The gas was potent and dense, signaling just how much she had been holding in throughout the day. A steady cloud of brown fumes began condensing in the area surrounding Catherine’s rear, and of course, Peter’s upper body. The smell was of something truly beyond comparison, as Catherine’s natural “brand” stunk like the depths of a septic tank. Peter could swear his nose hairs were curling up at the sensation, but his brain told him he loved every ounce of it, suffocating his lucidity.
Above him, and above the noise of her lengthy release, Helen nudged Catherine away, too impatient to play her little games of territorial control over the willing fart receptacle that was Peter. He felt the pressure of Catherine’s butt shift further down his body, migrating closer to his chest. In another second, he could feel Helen’s butt engulfing him from the top down, tussling his hair and forehead.
Even in a haze of brown butt smog, with his mind heavily distracted and his vision blocked by farts and booty, he was so well-accustomed to the two women’s divinely shaped rears that he could easily distinguish which was whose. Catherine, with a much more defined figure, had a nicely toned backside that had a texture like one would expect from an avid gym-goer who spent most of her time on the squat rack. An irresistible blend of fat and muscle, Catherine’s backside had a force to it that demanded Peter to yield to its pressing and squeezing, no matter its size. On the other hand, Helen, perhaps owing to her other superhero alter-ego’s suite of abilities, had a much softer, squishier pair of cheeks. Peter could sink into her booty like a pillow, comforted by its pleasurable, grasping texture and its perpetual aura of fart stink that it carried.
–SSSsssssssshh…HHHRRRRRAAAAMMMRRRRRRRRrrrrrr…–
Through it all, Catherine never ceased depositing her odorous cloud into Peter. And he, in turn, never ceased breathing in every last morsel he could get. He could tell she was toying with him, flexing her muscles to modulate her fart as it exited her. She was weaving in and out between a hiss and a tuba blast at will. God, he loved when she did that, just because she could.
–rrrRRRRAAAOORLRRRRLGRLGLRLLRRRRMMmmmmmMBBBRRR–
PPPRRRRRAAAAUUURRRRRRR…rrrRRRRRRFFRRFRRBBRR–
As the endless fart fumes continued to swarm through Peter’s nose and mouth, Helen began ripping her own fart. Hers was truly the definition of bassy, exploding over Peter’s eyes and nose with the sound of a entire brass section. Her unmistakable aroma of digested vegetables and heavy carbs began to emerge, slowly striking a balance against Catherine’s sulfuric stench.
The two continued their barrage atop Peter, who was savoring every moment of it. The cloud of brown and green surrounding him expanded to now fill the room uniformly, reducing the whole guest room into a hotbox. Catherine and Helen continued their tuba duet, modulating their tones every once in awhile with deft manipulation of their superpowered buttocks.
–GGGRRRGRRRMMBBRRRMMMMmmmm…mmMRRRRRRFFFFRRR–
–FFFFRRRrr…sssSSRRRRrrRRRRMM…mBBRRrrFFRRRRR–
As their flatulence raged on and on, Peter felt a high that no other inhalant could possibly match. His erection bulged against his pants with a desperate desire, greedy for more gas despite already getting more than he could handle. His mind was floating as the brown and green clouds of gas continued to sit heavy, growing in density with each passing second even as his lungs tried to filter them in vain. The gentle pressure of two pairs of massive buttocks weighing on his head and torso only added to his delirium.
Suddenly, mid-fart, Catherine began shifting her weight even more intensely on his chest.
Helen vocalized what Peter could not. “Cath, what are you doing?”
“I just thought I’d practice my twerking,” Catherine replied nonchalantly, the pressure waves on the bed growing in shameless strength.
“While farting on Peter?”
“It’s called multitasking, honey.”
–RRRRrr…rrRRRRT–TTRRRBRRT–PRRRT–PRRRSSSRT–PBRBRRT–
“Mmmm, mmm! Isn’t that just a sexy sound, Peter? My glorious butt stink, fighting to blast through my thick cheeks that clap together as I work ’em.”
Truly, it was. It wasn’t the first time she had twerk-farted, which always seemed to crank up the sex appeal for Peter by a factor of ten. Something about seeing her juicy cheeks open and close like that, while divine gas flooded out of them and swirled around in his airways, was an impressive and terribly sexy thing. But now that he could feel her twerking on his chest? Oh, man, that was something else.
–FFRRRT–RRRT–BBRRR–RRRRMMm–mmMRMRR–RRRRR–PPBRRR–
Not only could he feel the weight of her booty fluctuating on and off his body, but he could also feel the visible plumes of gas blanketing his torso as well, broken up by each cheek clap yet still depositing heavily into his airways.
Where most non-supers would have difficulty maintaining a good rhythm on their twerking on a yielding surface like a bed, Catherine was a natural at this. Her legs stood firm while her rear put on a show for all the senses, and Peter could not help but moan in unbearable pleasure. On his other side, Helen began to wiggle her hips from side to side, trying to match the tempo that Catherine had set.
“Helen, you want to give it a try? Show us what you’ve learned?”
Helen laughed, still effortlessly venting her enormous fart directly onto Peter’s head. “You think I’ve learned a whole lot about ‘twerking’ in the month that you’ve tried to teach me?”
Catherine put a hand over her mouth in mock surprise. “Are you implying I’m not a good teacher?”
“No, no…It’s just…” Peter heard the hesitance in her voice. “I mean, if you think I’m any good…”
Catherine guffawed. “Oh, please, Helen. You literally have elastic buttocks. Even if you were a slow learner, which you clearly are not, you would have picked this up from me in no time. I’ve seen you do it. It’s fantastic. Now bounce away, baby!”
With an audible smile, Helen replied, “Alright, Cath. Peter? I hope you’re ready for an earthquake tonight, because we are about to rock this bed off the Richter scale!”
–FFRRRR–RRRrrrr…rrrRRRR–PBRRRRR–BBRRMMM–MMMRRRRR–RRR-RRRRTTT–BBRRT–
–FRRRRSSSSSHH–FRRRSS–SSSSHH–PBRRRRR–BBBRRR–FRRRAARRRL–
Peter was experiencing a full-body stimulation of epic proportions. Every vibration of their fart release resonated through him. Every bounce and pop of their booty sent ripples along the bed beneath him and clapped gently along his face and chest. Every particle of gas making its way down his nose and mouth made him thirst for more, infusing his very existence with their farts. And every gleeful laughter that pierced their droning tuba sounds tickled his ears, reassuring him that it was all pure joy for the three of them.
“Mmm, what do you think, Peter? What…what do you think is hotter, the chest twerk, or the face twerk?”
“Obviously the face twerk, come on, Cath.”
–SSRRRRmm–MMRRRFFRR–FFRRRRPPT–FPRRPR–BBRRRR–RRROOOORRMM–mmmFRrrsss–
–PBRRRT–RRT–RRRPRRRR–SSRRT–SSSrrssshh–SSSHH–SSSSST–FFFRRRRRT–PPRRRT–
“Mm, I want to hear him choose.”
His moans came as fast as their broken farts now, only serving to accelerate his breathing and help his gaseous intake. The two supers were never one to stop to give him a break — not that he would ever ask for one — and so their flatulence raged on and on, blasting away, curious to see how much more Peter could take. They knew he was never going to stop sniffing to bother giving them a concrete answer, and they were perfectly content with that.
“My butt is clasping around his face over and over again, Cath. Come on. You know you can’t beat that.”
“Oh, I don’t know, my booty is slamming into his body, hammering at his chest and forcing him to breathe in my — or, our — nasty fumes. It’s like an entirely butt-based CPR. I think that’ll give yours a run for its money.”
“I’m pumping gas down his throat. Excuse me, I think that wins by default.”
Catherine laughed. “What happened to ‘it’s not a contest?'”
“Hah, shut up.”
Without a proper response from their fart boy below, they never relented, shaking their booties and farting away with reckless abandon. The room door began leaking brownish-green gas under it, and slowly but surely, the whole apartment stunk like the deepest reaches of their gassy bowels.
Barely conscious in his orgasmic stupor, Peter could only think: what an amazing way to end the day.
PART 2
Peter stirred awake, his eyes still closed but his nose already picking up the unmistakable stench of Helen and Catherine's farts. It was a sensory stimulus that he had long grown familiar with by now, and at low concentrations, he barely even registered it. He was certain that every inch of wallpaper was permanently stained with trace amounts of the brown and green gas that swirled around on a regular basis. His mind conjured images of Helen and Catherine absolutely blasting away through the night in their guest room, polluting the air around them even as they were unconscious. He shifted in his bed to one side, getting his morning wood comfortable as it twitched eagerly.
This morning, however, as his consciousness slowly warmed up like a decrepit computer, he began to register that the gas entering his nostrils was much, much stronger than on any other morning. In fact, he began to feel a cough rising in his chest, his biological drive kicking in and pleading against the foul miasma filling his lungs.
Understanding that his day had started, one way or another, he opened his eyes.
Oh, holy fuck.
The scene around him was not what he expected. His bedroom was entirely covered in a thick, dense fog of greenish brown, reducing visibility to the point where he couldn't see his door on the other side of the room. It was as if a layer of smoke coated every possible surface. When he kicked off his sheets, he saw wispy trails of gas in the air swirling, agitated by the sudden motion. His first course of action was to take in a deeper lungful, his erection thinking for him faster than his still-sleepy brain. This was a poor choice, however, as he was
immediately met with a fit of coughs, clearly having taken in too much for him to physically handle at once.
"Oh, good morning, Peter. Enjoying our little wake-up call?" Catherine's voice rung out from behind the smog. Though he couldn't see her through the impressive, thick haze of utterly incomprehensible fart gas, he could very much hear her holding back laughter.
Between coughs, stabilizing his breathing, Peter managed to say, "Wh...Hoo...Wha-, What did you do...?"
Helen's voice came from near Catherine. "Oh, we've just been bursting at the seams since we woke up. We thought we'd try something a little...different."
Catherine clarified, "We've been standing at the door over here, just blowing silent farts in your direction for the past several minutes. We were wondering how long it would take for the smell to wake you."
"Evidently, the answer was, 'longer than it takes for us to fog up the whole room,'" Helen jumped in. "Your 'resistance' to our farts seems to be getting much stronger."
"Hnnh..." Peter managed to settling his breathing. Every intake felt like a lungful of smoke, burning deep into his core and sexually exciting him. "Yeah, I guess that's what repeated exposure does to you."
"I guess, but this is truly insane, Peter. God, I can't wait to sit on your face again..." Catherine teased.
"We'll get to that in a bit," Helen chastised. "In the meantime, I think we've been standing here long enough."
"Wait, how long have you been standing over there, hotboxing the room?"
A pause. "Twenty minutes? A bit more?"
Wow. Twenty minutes of non-stop SBDs, pumped directly from two super-farters' thick booties into his room's air supply. It was mind-boggling just how gassy these two could be, and he wanted to savor every moment.
"Oh, and we don't want to see you come out of your room until the air here is completely clear," Helen said, suddenly adopting a stern, motherly tone. "Understand? Consider it a 'punishment' for oversleeping." Peter could hear her fighting back snickers, as even she realized the ridiculousness of such a statement.
"Like that's going to be a problem for you," Catherine added gleefully.
"...Yes ma'am."
PPBBRRRBRBBRBRRRRRRMMFFRRT
"Enjoy~!"
With one last short, bassy fart and a resounding smack across her butt to congratulate herself, Catherine left Peter's room and closed the door. Peter shuddered, his whole body shivering with arousal.
His hands began working at his morning wood, and his nose began working at Helen's 'punishment.'
~~~~~~~~~~~~~~~~~
Helen had to admit that this developing dynamic with Catherine and Peter was something to relish. At first, of course, she was somewhat hesitant, and worried about going overboard. However, over the past month, something about falling into their unspoken customs of farting and sniffing had begun to feel like a casual bit of fun to have. It became something to look forward to at the end of each day, and if she was being honest with herself, it made her feel younger somehow. It was hard to deny that she enjoyed feeling sexy for someone new. It was invigorating. Empowering, even. There was something irresistible about getting Peter all worked up by reforming her elastic body into an impossibly seductive figure, or even just cocking her hips and biting her lip the right way.
And the farting. Ohh, the farting. She still had no idea how uncommon it was for a super to develop new powers this late, especially ones so incompatible with the others. But what she did know was just how irksome it felt to hold in such massive pressure in her gut and just how delectable it felt to unload it all. Even if Peter wasn't there to sniff it up, releasing her farts would bring waves of pleasure. But Peter was there, and he was very much enjoying her gas, fulfilling her twofold need of unleashing her incredible farts and feeling as racy as someone half her age.
In essence, the past month had been a fantastic experience demonstrating just how much fun she could be having. Catherine might get out of hand every once in awhile, but she was right: Helen needed to loosen up a little. Peter had proven to her that her newest gassy abilities weren't necessarily something she had to "manage" or "suppress," but rather something that could be fun, exciting, and even sexy, if she found the right guy to mess with. She hadn't quite worked out how she would work her farts into the whole "Elastigirl" shtick when she did get back home, but she still had plenty of time to figure things out.
In the meantime, she savored the moment. And right now, that moment was watching Catherine bound into the living room, her assets bouncing freely. Helen took it all in, admiring how she embodied two things: a youthful energy that radiated a fun-loving nature, and the sexual appetite that tends to come alongside that energy.
"Oh, man. I still can't believe we did that," she was saying, her magnificent buttocks swaying their weight from side to side in each step.
Helen smirked. "To be quite honest? I've been thinking about it this whole time," she said, leaning over to make room for Catherine's copious figure on the couch. "With the endless gas we both have, if we just kept farting and farting, we could probably fog up the whole apartment. It would just be a matter of time."
Catherine grinned, taking her seat. "Yes. If we just kept farting, and farting, and farting...Ooh, baby..."
Helen knew that tone of voice. She glanced over at Catherine's rear, watching in anticipation. As expected, the telltale brown mist began emerging from the crevasse between her scrumptious cheeks, betraying its complete silence. The way she was sitting on the couch meant a majority of the gas was being deposited into the poor fabric of the seat, which was absorbing as much as it could. But in the tiny spaces left between the surface of her hefty buttocks and the couch, the intoxicating fumes were filtering through. It was little gas (compared to their usual standards), but the amount reaching Helen's nose was plenty enough to titillate her senses. Her hairs seemed to stand on end as she took it in, just enough to stimulate her and leave her wanting more. It was different than getting a full facial blast, and she began to drift closer to her partner.
"You like the stealthy ones, yeah?" Catherine raised an eyebrow, brown gas still lifting from underneath her.
"Mmm..." Helen declined to answer at first. "Bassy ones are good too. The ones that ripple your butt and burst out? Ooh, it's hard to say which is better."
Catherine nodded along. "The ones that sound like a tuba note," she agreed.
"A very stinky tuba." They shared a laugh.
"You know, Peter's still got some time before he's ready for the day..." Catherine said suggestively, adjusting her pose on the couch. She slid over to one side, presenting her buttocks to Helen as she placed her elbows on the armrest and bent over it.
Her elastic companion took the hint. "Yeah?"
"Why don't we make the most of it?"
PPSSsssssssshhhhhhhh...
A "silent"-but-deadly fart rasped its way out of Helen's thick booty, its sheer volume creating quite the noise. As it blew on and on, Helen slowly turned herself around as well, pointing her impossibly alluring derriere at Catherine. When she found a satisfactory position, she pulled the trigger.
sssssSSSSSFRRRRRFFFFFFRRRAAAOOUUURRRRBBBBBMMMMM--
At will, Helen opened her sphincter up further, allowing even more gas to ripple through her rubber-like buttocks at a faster rate. Cranking up the pressure brought the volume of her fart from a whisper to a deep, shaking bass, while the wispy green plume coming out of her booty turned into an air cannon.
Not to be outdone, Catherine responded with another silent fart of her own, throwing out delectable brown fumes to meet Helen's green in the middle. She smiled deviously as it ran its course, locking eyes with Helen.
"Bombs away!"
ppPPBBRRRRRRAAAAAAAAUUURRRRMMMM--
Their farts continued to blast away, alternating between the silent, lingering cloud-makers and the shamelessly loud, brassy ones that visibly smacked against the far wall. They soon stopped teasing each other with words in favor of saving that lung capacity for inhaling as much as possible.
As much as they took their own flatulence into their airways, however, their gaseous output was far more than they could handle. The room quickly fogged up around them, with not a morsel of fresh air in sight. Not that they minded, anyway.
"Mmm...God, I wonder if we could do the same thing to the living room. Like, fog the whole place up..." Catherine said in a rare moment between farts.
"That's what I was saying earlier!" Helen bent even further, squeezing herself tighter to get even more gas rushing out of her exit.
BBRBRRRRMRMMMMmmmMMMRRRRRRRRRAAAAOOOUUURRRRLL--
"So, now that we've put them all on display, which do you prefer? Bassy or silent?"
Helen adjusted her seat, now leaning on her side. She lifted a leg as she spoke, casually ripping another monster fart. "Hmm, you know, I'm not sure. Why don't you give me another sampler?"
Catherine clutched the armrest tighter, boring down and loading into position a true room-clearing fart. "Okay, but only if you promise to get in real close." She smirked.
FFRFRRRRRRFFFFRRRMMMMMMMMMRRRRRRRRRRRRRPPPPPBBBRRR--
Helen wasted no time in driving her face as deep as it would go through the thick booty meat of her companion. It was like fighting through the force of a hurricane as she struggled to get herself as close as possible to the epicenter of Catherine's explosion, which had already been erupting for more than ten seconds and showed no signs of stopping.
--RRRRRRRRROOOOOOUUUUURRRRRMMMMMmmmmmmssss--
Catherine, true to her word, deliberately manipulated her buttocks with her body-morphing powers to shift this fart into a new form in its second half. By expanding herself even further, the gas began filtering through at a slower rate, rushing by with a weakened sound until it decrescendoed into a near-silent hiss. Her butt expansion had the added effect of driving Helen's head even deeper into the odorous crevasse, which neither of them wanted to rectify.
The stinky silent winds continued rushing into Helen's nostrils and mouth for countless more seconds before Catherine cut herself off and Helen pulled herself out from deep within her booty.
"So?"
Helen took a moment to settle her breathing. She could feel that her hair was all tussled from just how deep she was, but she didn't care. A chance to dive that far into Catherine's buttocks was practically a taste of heaven at this point. "Ugh. They're both so good, Cath. You're so good at blasting those beautiful farts, it's making it hard."
"Always the indecisive one," Catherine joked.
"Hey! It was a compliment!"
"Ah, calm down," Catherine laughed. "My turn to make the call."
"Oomf!"
Catherine barely gave Helen a chance to settle down before she turned around, giving Helen's ample backside a few circular rubs before jamming herself between its cheeks. Helen yelped in surprise, but then let a smile overtake her face, far too amused by just how fart-hungry her partner was. Wordlessly, she rubbed her stomach, feeling another volatile expulsion waiting to slam into Catherine's airways.
...ssssSSSSHHHHHHHHHHRRRRRRRRR--
This time, Helen took the opposite route, starting with a loosened anal ring to blow out a completely silent fart and gradually tightening herself up to create an audible puttering sound. As the sound picked up in volume, it took on a more tuba-like tone, becoming more and more dominant as it rung out through the living room.
--RRRRRBBBBPPRBRPRRBBBPPRRMMM--
Catherine's sniffing was completely inaudible over the room-quaking bass at this point. Helen looked back in awe as smoky clouds of green emerged from the cracks between her hips and Catherine's head. As she watched in surprise, Catherine's impressive lung capacity managed to draw in motes of gas that were floating freely a few inches above where her face was planted in her own butt.
--MMMPPFFRRRRRFFFFFFFFRRRTTT
"You're making me jealous back there, Cath," Helen said, giggling while she pushed more gas through her system, preparing to unload another behemoth fart.
Catherine came up for air. "You know, that reminds me," she said between hungry sniffs, taking in what little stink she had missed. "I've been thinking."
"About?"
"Your powers. You know, your elastic ones. You can bend yourself into any shape you want, right?"
"Uh huh..." Helen rubbed her backside gingerly.
"You could probably, you know, put your face right where your own butt is. Or, your butt where your face is...I mean, whatever works."
"Hmm." Helen pondered for a moment, picturing various configurations of body geometry to make such a thing happen. It felt so dirty, sniffing her own farts directly from the source, but now she was too curious to let it go.
Settling on a pose, she detached herself from Catherine, stood up, and began stretching. Catherine took a step back to give her some more space.
The pose she had chosen was elegant in its simplicity: she had bent over backwards to stretch her upper body in a curved position until she was eye-to-butt. Finding her new center of gravity, she adjusted her weight distribution until she could sit comfortably on her own face, resting her juicy cheeks on herself with her elastic waist tethering them together. Then, she focused on her brewing gas inside.
As the gas made its way up and down her tract, she could feel it snake through her elongated body, swirling around like a silky beast that desperately sought a way to break free. Once she felt it pounding away at her back door, she emptied her lungs and prepared to fill them with her own stench.
pPPRPRRRRRRAAAARRRRRRRRRRRLLLBRRRBBBBBBRRRMMMMPPT
It was shorter by her standards, but that still meant it raged on for several seconds, giving her plenty of time to take in lungful after lungful of terribly tainted green musk.
"Oh, that is just wonderful!" Catherine clapped with joy at such a spectacle. "Mmm, mmm, mmm! I wish I could do that!"
Helen could only moan in response. God, it felt so dirty, and so, so good...
BBBRRBRBRBRRRRRRRMMMRRRRLLLLLLLAAAOOOURRRRPPT
"How is it?" Catherine asked expectantly.
"MMmmmmm...Oooh, it's just...so much more different when I'm not sniffing my own brand from the air," Helen said, her eyes still closed in enjoyment. "It's less stale, you know? More fresh. The gas just has a different texture..."
"I would think it's the fresh heat that adds to its 'flavor,' you know?" Catherine speculated. "Steamy hot gas just hits you different."
FFFRRRRRRRRMMMMMMMMmmmmmmmmmssssssssssss...
"Nngh...Oh, I'm inclined to agree."
Helen looked up at Catherine for a moment, who was taking position with her hands on her knees, bending over again to brace herself for even more gas to blast out of her. As she did so, she dipped her head down as low as possible, bringing her face closer to her crotch area. "Hey, I'm not letting you have all the fun," Catherine said, meeting Helen's gaze. "I'm doing the best I can over here, trying to sniff my own farts."
Helen chuckled. "Hey, I look ridiculous over here too," she said. "But who cares? As long as I can get a good front-row experience..."
sssSSSSSRRRRRRRRRAAAAAAPPPT
The two of them continued in this way for quite some more time, dumping ungodly levels of poisonous flatulence into the already well-tainted air. Taking their own farts in a nearmasturbatory self-indulgence with their own super-booties, they quickly exhausted themselves. It was, after all, the first time they had to focus on both venting immense farts and taking deep inhalations.
"Ahhh..." Catherine fell onto her back after their little experiment had passed, sighing with relief and pleasure. "I could do this all day..."
"Mm." Helen sighed. "Are we going to?"
"Actually..." Catherine suddenly picked her head up. "You know, I was thinking about another way to play with Peter for a bit. You interested?"
"Oh, always."
"Then get dressed." Without warning, Catherine rose. "I'll go see how Peter's doing."
Helen frowned. "Wait, dressed? Like we're going outside? In broad daylight? Cath, I know this--"
"Shhh." Catherine smiled, mischief in her eyes. "Don't worry about it."
~~~~~~~~~~~~~~~
"An open window! Oh, the betrayal!"
Catherine cried out melodramatically at the sight of Peter lying in bed, visibly spent, with the one window in the room open by just a crack.
"Hey, it's not what it looks like," Peter retorted. "The room was just getting unbearably hot, no thanks to you. Believe me, I filtered every last particle of fart gas through my lungs before I even dared to crack a window."
"Hmm, how can I believe you?" Catherine placed a hand on one hip.
Peter folded his arms. "Do you really think I would dare let any of your beautiful farts to go to waste?"
Catherine smirked at that. "Okay, fine. But close that window right now, Helen and I have already fumigated the living room while you were busy."
Peter gladly obliged. "Oh, glad to hear it."
"You know, Peter," Catherine continued, "I've been thinking we need to get out more. We're always so cooped up in here, I think it's high time we do something fun outside."
"What were you thinking?"
"Oh, I don't know..." Catherine took things slow, pacing gently around the room with a spring in her step to jiggle her bubbly booty. "There's a park that we noticed is always deserted, right on the outskirts of town," Catherine said. "What do you think about just taking a nice stroll?"
"Vermosa Park? Yeah, no one really goes there. Some rumor about coyotes, or something. I think it's bullshit, I've been there and I haven't seen any."
"Don't coyotes have an enhanced sense of smell?" Catherine mused with a hand idly tapping by her mouth. "Even if there were any, I think they'll be giving us a wide berth. We are superheroes after all." She smirked. "What do you say? A walk in the park, escorted by two gassy babes?"
"And a 'protective' cloud of stench..." Peter finished the thought. He smiled. "Sounds good to me."
"We'll have to drive there, though," Catherine said in a slightly suggestive tone. "You know, super-identities still need to be kept secret while we're in town."
Peter caught on. "We'll keep the windows rolled up," he said, winking.
Catherine pouted. "That's not going to be good for you," she said mockingly. "I should warn you right now...I'm feeling just a teensy bit gassy."
Peter laughed. What an understatement.
~~~~~~~~~~~~~~~~~~~
The trio arrived at the park with no issue. Brown and green gas swirled around the interior of the car as the result of countless silent bombs dropped in the tight space. It was quite the feat, considering the drive was less than ten minutes.
The moment they parked, Catherine unfastened her seatbelt from the back seat, turned around, and placed her buttocks squarely between the two front seats. Expanding her booty until she couldn't anymore, and unleashed a stream of eggy gas that fogged up the whole front windshield in a matter of seconds.
"It's a good thing you didn't do that while we were on the road," Helen remarked.
"Duh. I didn't want to get into an accident." Catherine rolled her eyes, still steaming up the whole front half of Peter's car with copious amounts of brown gas.
"You don't seem too eager to get out of the car there, Peter," Helen said teasingly. "What for? We're here."
"You know, it's just nice and toasty in here, for some reason." Peter tried to meet eyes with Helen, but found it difficult with the gas cannon planted firmly between them.
Helen opened her door first. "Come on, you two. We'll have time to hotbox this car even more when we get back."
As Peter got out of the car, he watched a smoke screen of brown and green farts emerge alongside him. His nose took a moment to readjust to the fresh air outside as his car leaked bits of gas from every possible open space, from the cracks between the doors to the edges of the windows.
Helen and Catherine were stretching on the other side of the car. "Alrighty then, Peter," Catherine said, straightening out her jacket. "Here's the plan. We're going to walk a few steps ahead of you so that you can, uh, 'feel safer' about where we're headed. Sound like a plan?"
"I'm not going to say no to that kind of offer."
Peter found it difficult to contain his springing erection as he walked just a few steps behind the two of them. Of course, all of his attention was directed at the gorgeous sight of their bouncing booties, which looked so alluring in the natural light. Catherine in particular seemed to put enough spring in every step to make a light clapping noise between her cheeks.
They had only gotten a few steps into the park when Helen and Catherine glanced knowingly at each other. Then, Peter's view got a whole lot better.
BBBRR--RRRRRRMMM--RMMMRRR--RRRRRSS-SSSSSSSSHHH
FFSSSSSSsssssssss...
From the left, Catherine immediately pierced the relative calm of the outdoors with a shattering tuba fart that was interrupted with every step. From the right, Helen had elected crop-dust Peter with a dense cloud of green that hung thick in the air, emerging with only a telltale hissing sound that could barely be heard.
"I see we have different strategies to venting excess gas while walking," Catherine said to Helen without missing a step. "I do think I prefer my style, myself."
"Oh, Cath, always competitive, and always so bold and brash."
Peter was barely listening. Having gotten re-accustomed to the clean, untainted air of the quaint little park, the double wave of stench nearly brought him to his knees. The fart cloud clung to him like a mass of flies, refusing to dissipate until he had his fair share of it. He slowly readjusted to the stench as his arousal rose.
"Come on, Peter," Catherine called from further ahead. "Gotta keep up!"
BBBBRRRRRRRRPRRPRPRFFFFRRRRRRR--RRRRRRRMMMMMMAAAAOOUUUURRRRT
"Forget coyotes. Every animal with a functioning nose in this park has just fled," Helen said with a laugh.
BRRR-RRRPRR--PPPRRRR--RRRMMM-MMRPBRR-BRROOOUR--RRRT
FFRRRRRRSSSSSSSSsssssshhhh
The two super-gassy women continued their bombardment as they walked at a brisk pace, keeping Peter just far back enough to move through an intensely thick wall of brown and green fumes with each step he took. Peter could hear them having some kind of discussion over whose style of cropdusting was better. Frankly, he wasn't sure he cared. Catherine's method was reminiscent of their twerk-farting fun from earlier, with each booty clap punctuating every break in her gaseous release. The brown cloud she was emitting followed suit, leaving swirling bursts of concentrated stench periodically behind her. Meanwhile, Helen's approach was much more teasing, as if leaving behind an olfactory trail for Peter to follow. Neither one topped the other, and with each inhalation, Peter could feel his erection aching for another release. Still, he managed to maintain his composure, taking in every breath of gas like an invigorating gulp of cold water to energize him.
PRRR--RRRRRMMM--MMBBBRR--PRRRFF--FFFFRRSSSHH--SSSSSHHHHH
FFFFFFSSSSSSSSSssssssssssssshhhhhhh...
Though the walk around the small, secluded park was only maybe half an hour, this perpetual sexual torment made it feel much longer. Peter barely noticed that they had circled back around to the parking lot when Helen and Catherine abruptly stopped in front of him.
"Hey, Helen?" Catherine saw a golden opportunity. "Your shoe's untied."
"Oh, whoops."
Peter watched as Helen casually bent down to reach for her shoes, the motion once again forcing her booty meat into a position where it bulged outward at Peter behind her. Peter stopped dead in his tracks to drink in the sight. Each bulbous cheek seemed to move in slow motion as she casually drifted her weight from side to side, and it took Peter some restraint to not lunge forward and shove his head into its warm, soft, inviting crevasse. He caught a glimpse of Helen winking at him before his vision blurred into a wall of green.
fffFFFFSSSSSSRRRRRRRRMMMRRMRRRBBRRRRrAAAAOOOLLLLRRRRRRRRPPPPPBBRRRPPPT
Helen had somehow managed to pack in a minute-long fart's worth of gas into a single, five-second release. The sheer density of her green expulsion was incredible, and something that Peter had not yet seen in their month of gassy fun. Clearly, Helen was getting even more accustomed to her new powers, molding not only her form but also her gas as she desired.
The super-dense fart punched Peter in the face and siphoned itself into his airways, where it sat heavy and refused to let him take a full breath. He began lightly heaving, the impossibly thick gas invading his lungs much too quickly.
Catherine and Helen, meanwhile, were standing over him, their butts in his direction, ready to deliver a second blow without any respite.
PPPBRRRBBRBBBRRRRRRRMMMMMMFRRRRRFFFFFFFRRRSSSSSSSSHHH
SSSSPPPRPRRRRAAAAOOORRRMMMMMMRRRFFRRTT
Their unrelenting farts knocked Peter into another world. He could have sworn he briefly saw stars as they punched into his lungs, this time with even more force than Helen's solo blast.
"Alright, we've toyed with him enough," he heard Helen say. "Come on, Peter. Unlock the car."
Peter stumbled to his feet, still struggling to hold himself together. This was an absolutely incredible experience. He thought he had built up a strong "tolerance" for their farts after all this time, as evidenced by their little morning hotboxing experiment. However, these farts in the park showed that Helen and Catherine might have actually been holding back more than he thought. Now that he showed his readiness, he might be in for another world of fart-based pleasures. He mindlessly got into the car and placed the key in the ignition, ready to drive home and pitch the idea.
"Hey, hey," Catherine interrupted his thoughts, placing a hand over Peter's as he grabbed the gear-shift. "What's the rush?"
"What...What do you have in mind?" Peter raised an eyebrow. Catherine only smirked at Helen in response.
"You know, Cath, if we're planning on doing anything crazy in the car, I think it's best if we...'fog up the windows?'" Helen winked.
Catherined smiled back. "Oh, gosh, absolutely," she said gleefully, before raising her buttocks off her seat and sending vibrations throughout the whole car. Helen smiled as she took position to do the same.
bbBBBBBBRRRRRRRRMMMMMMMMM--
pPPRRRRRRRRRRRAAAAOOOOORRR--
"Just give us a minute, Peter," Catherine said over the bassy sound of their powerful, explosive gas. "We won't keep you waiting for long..."
