“Oh, come on, Red, put me down already. We haven’t even picked a safe word yet,” Catwoman purred.
“Hush, Selina. You know why you’re up there.”
“Mmmm, I’m not sure I do. Care to show me?” She licked her smirking lips as she spoke, but she got no response.
Beneath her sultry exterior, hanging upside-down from the thick vines restraining her on the ceiling, Catwoman was fuming. She could hardly call herself a master thief after this—hell, this wasn’t even one of the first half-dozen times she had broken into Poison Ivy’s lair without tripping any of her alarms. And yet Ivy was practically waiting for her once she got to the penthouse floor. She was still playing back the events of the night in her head, trying to figure out where she went wrong. Poison Ivy must have beefed up her security, as if she had been anticipating an incursion. But Catwoman would have surely noticed any new additions to her defenses, so what was she missing?
“You’ve double-crossed me for the last time, Selina,” Ivy was saying, sitting daintily in a throne of leaves a few feet in front of her. “I should have dealt with you after the incident with Strange.”
“Come on, Red. We both know you can’t bring yourself to hurt dear old me, can you?”
“Hmmph.” Ivy pursed her lips as she silently willed her plants to pull her up, face-to-face with Catwoman. “Don’t be mistaken, Selina. I don’t have to physically hurt you to deal with you. Physical torment is so…barbaric. But I have other ways.”
Catwoman scoffed. “What’s that supposed to mean?”
“I’ve been experimenting with more potent pheromones,” Ivy began, rising from her seat and turning her back on her prisoner. “Pheromones that can retain their hold on a mind for longer, and with even finer control over their willpower.” Catwoman couldn’t help but be briefly distracted by the sight of her delicate green bottom, which were not covered by her usual tattered red panties. She hadn’t noticed while Ivy was seated, but it was surely hard to miss now.
“Pheromones?” Catwoman rolled her eyes. “I keep telling you, Red, if you want a boyfriend, you should try a dating app. None of this enslavement nonsense.”
“Silence!” Ivy turned to glare at her, accentuating her word by tightening her grip on Catwoman. Additional vines snaked down from the ceiling, slowly moving to cover her mouth. Catwoman could hardly resist at this point, but she made sure to roll her eyes again while Ivy was looking.
“I’m still working out the details,” Ivy said. “And I need test subjects with stronger wills than the feeble men I keep in store. That’s where you come in.”
Catwoman felt herself being carried closer to Ivy’s perch. She noticed two other things: that her head was level with Ivy’s rear, and that she was subtly rubbing a spot on her abdomen.
“I believe I’ve found a way to integrate the abilities of my plants with the abilities of my human body,” Ivy continued, placing a little extra disdain on the word “human” even as she referred to herself. “I won’t bore you with the details—I’m not sure you’ll even remember them. The point is, I’ve been using myself as a sort of…reactor for more powerful toxins.”
By this point, Catwoman had been pulled to less than a foot away from Ivy, who kept her stoic stance as she faced away from her captive. Selina noticed she was rubbing her belly a little faster, and her suspicions grew as a vivid growl escaped her stomach.
Red, you better not be doing what I think you’re doing. Catwoman gave the room another sweep with her eyes for a way out, but she knew there was no hope by this point.
“Open wide for me, Selina.” Ivy bent over, holding what would have been an elegant, coquettish pose if not for what came out of her backside.
BBRRRRRRRAAAAAOOOMMMMMMFFFFFT
Ivy’s strained groan was hardly audible over the bassy bombardment that Catwoman took to her face. A flood of gas, so thick and dense that it was practically visible, blew into her airways with surprising speed. A cloud immediately hung around her head, bringing the temperature up by a few noticeable degrees as she thrashed about.
“Mmmmff!”
The stench was horrendous, reeking heavily of rotting vegetables and sewage. By reflex, she began trying to cough, but the vines held tight against her mouth, leaving her only to heave deep breaths in and out of her nose. As more of the foul air flooded her senses, she could feel a slight tingling in her brain, but she couldn’t afford to pay it much mind at the moment. Each breath she took was agonizing, though the air seemed to clear up just a little bit with each nasal filtering she was forced to do.
She caught Ivy’s gaze smirking at her victoriously as she struggled to regulate her breath. Whatever attraction she had to the redhead’s slim rear beforehand was wiped clean from her brain.
As her breathing slowed, Ivy’s smirk faded. “Hmmph. Still kicking?”
Catwoman glared back at her.
“I’ll have to strengthen the concentration…” Ivy made a gesture with her free hand, the other still fervently rubbing her strained gut. “But then again, I wouldn’t be able to have this kind of fun…”
Catwoman felt the vines lurch her forward a few more inches, putting even less space between Ivy’s succulent cheeks and her poor nose.
“Nnh!”
PRPRRRRRRAAARRRRMMMMFFFSSSSSSSS
Another shot of horrid, thick gas blasted out of Ivy’s backside. At this range, there was little room for the fart to dissipate out into the air; and with Catwoman hanging upside down, her nostrils were in the perfect position for the stink to rush in. It practically felt like a gaseous injection right into her lungs. The vines continued to hold tight onto her as she choked down a gag, not wanting to vomit into a sealed mouth but suffering immensely from the stench. The smell of decaying vegetable matter was engrained into her mind, as was the sight of Ivy’s flaring butthole pushing out an incredible volume of gas.
“Mmmfff…”
PRRRSSSSSHHHH
Another fart, shorter this time, but no less vile in its stench; if anything, it was twice as bad. Catwoman wasn’t sure if it was because she was caught off guard by the second fart, or if it was because it was a silent but deadly hisser. At any rate, her mind wasn’t equipped to process it, and the tingling in her head grew more persistent.
“Mmmm, I’m so glad you’re so strong-willed, Selina. It makes breaking you so much more fun.” Ivy made another gesture, harder this time, with the same hand. Catwoman felt her whole body lunge even further, making the inevitable contact against her captor’s rear. Ivy’s cheeks were surprisingly soft and pillowy, and Catwoman was caught off guard by how sensual it felt to have her face right there between them. To her surprise, even the stench of her latest blasts seemed weaker than she imagined. Without a thought, she wiggled back and forth, craning her neck to nestle her face deeper into Ivy’s crack.
Catwoman felt a hand on her chin aiding her efforts. Ivy’s voice sounded so distant, like she was underwater. “That’s right, Selina. Give in to my toxins…Let them corrupt your mind.”
Toxins? Oh, fuck. Toxins!
A voice in the back of her mind screamed at her that this was part of Ivy’s ploy, and that she was in danger if she wasn’t able to get out of this predicament. But it was too little, too soon. What little lucidity she had left in her was blown out of her…literally.
BRRRRRRRRRRRRRAARRRRRRRRPPPTT
A brassy fart rung out, echoing slightly in the small chamber they were in. With her nose pressed against Ivy’s rosebud, she felt every second of the blast, from the puckering of her dainty hole to the wind tunnel sensation blowing into her sinuses. The rotten odor exploded into her lungs and filled her mind with Ivy’s pheromones, and the fight was now entirely out of Catwoman. Through the vines gagging her, she felt a moan escape her.
“Nnnnhhh…”
Ivy chuckled. “There we are. How does that feel, Selina? To give yourself over to me so readily?”
Catwoman couldn’t muster a reply, even if the vines weren’t pressing against her mouth. The sensation was impossible to compare to anything else. The rotten stench of Ivy’s vile farts still hung thick in the air, and it did indeed still smell powerful. Yet it was now also…alluring, in a strange way, beckoning out to her. It was arousing, and in more than just a sexual way; it occupied her entire being, and the thought of being Ivy’s permanent fart slave was becoming more seductive by the second. She wanted more. She needed more.
“Your flesh is weak, Selina. Your body is mine to control. And all because of a few…”
PRPRRRRRRAARRT
“Aahh…simple doses of my ‘toxin.’” Ivy giggled again, relishing in the sensation of Catwoman sniffing up her farts so eagerly now. She could feel the suction of Selina’s diligent nostrils working against her butthole, practically vacuuming more gas out of her gut before she could even open fire again.
Catwoman, meanwhile, was in overdrive. The only lament now was that her hands couldn’t reach her aching pussy, which was certainly moistening now and might soon drip onto her hips and abdomen if this continued. More moans strained out against the vines shamelessly.
Ivy snapped her fingers, and the vines released Catwoman’s lips. Almost immediately, a string of surprisingly loud moans escaped between each eager sniff of residual gas from Ivy’s puckering hole, lightly echoing in the chamber.
“My, my, Selina…For a master thief, you are quite a loud one.”
PPRRRRRRARRRMMMPPT
“Gaahhh!”
As another pungent fart rocketed into her, Catwoman couldn’t help herself as another moan flew out of her. She almost sounded as if she was being fucked, and something had just hit her sweet spot; but instead, it was a foul concoction hitting her nose. She didn’t care. Ivy’s farts were now her whole world, and she would give up anything to have more of them invade her greedy lungs.
PRPRPRRRAAARRLLT
GGRRRRMMRMRRRRRT
FFRRRSSSSSSSS
Thankfully, she didn’t have to give up anything. Ivy, still chuckling to herself at the sight of it all, rewarded her with a series of blasts. It was a delicious sensation, and she could swear that her little slave was inhaling her gifts faster than she could unleash them.
Meanwhile, in her toxin-addled mind, Ivy was the most generous mistress Catwoman could hope for. She frantically sniffed it all up, groaning between breaths. Her hands tried to move to her dripping loins, but they couldn’t reach. She tried to remember why, but abandoned that thought as soon as it came.
“More…More, please…”
Ivy put her hands on her knees, bracing into position. “More?” She could feel another barrage snaking down her gut. “Well then. Ask, and you shall receive…”
PRRRRRRAARRRMMT
FFFFFRRRRRAAAAPPPT
BBBBRRROOOOAAAARRRT
PPRRRRSSSSSSSHHHT
Only a biologically altered woman like Poison Ivy could pull off such an impressive gastric feat of blasting out four violent farts in rapid succession. She couldn’t help but moan herself as she felt the monstrous expulsions leave her, deflating her stomach considerably.
Meanwhile, the frantic sniffs behind her were weakening. By the time Ivy realized what was happening, she turned to see Catwoman on the brink of exhaustion, her brain and lungs overtaken by the sheer density of gas and toxin. She willed her vines to release her, depositing her unceremoniously onto the cold floor in a mess of drool, stench, and arousal.
“Mmm…mmmaaooorrree…”
Ivy clicked her tongue. “My, my, Selina. It seems you’ve overdosed. We’ll have to work on your conditioning before you get any more.”
As her senses faded, Catwoman felt vines whirl around her.
~~~~~~~~~~~~~~~~~~~~~
“Ugh…”
Catwoman woke feeling groggy. Her senses were dulled, far from their typical heightened standards that would befit her identity. As such, it took her a little while to realize she wasn’t in her bed. As a matter of fact, she wasn’t in any bed at all. She looked around, seeing that she was in some kind of enclosed chamber with organically curved walls and uncomfortably low ceilings. There was enough space for her to move around, roughly the dimensions of a decent camping tent; but the walls were thick and opaque and green, and…fibrous?
At the other end of the chamber was a clearly humanoid figure, colorfully outfitted with red and black patterns. It took her a second to realize who she was looking at.
“Harley Quinn?”
No response. She was unconscious, probably having suffered the same fate she did. Which was…what exactly? She couldn’t remember, but it danced on the tip of her tongue.
BBBRRRRRARRRRT
A low, bassy hum droned out of Harley’s tight spandex ass, and suddenly the pieces came together in Catwoman’s mind. The capture, the talk of pheromones and toxins, the farts…
Part of her mind fought for control, attempting to restrain her arousal at just revisiting the events before her blackout. Perhaps her sanity would have won out—if not for her unconscious roommate.
BBRRRRRMRRrrrrrrrrrrrrrrrrRRRRRRT
Another bassy fart escaped Harley’s curvaceous bubble butt, and Catwoman felt herself slipping away. The sound was already enough to ignite some salacious thoughts, but the smell…Oh, the smell. In their tightly enclosed space—which, Catwoman gathered, was one of Ivy’s flower pods she used to keep men restrained—the odor of Harley’s fart had nowhere to go but her lungs. The faint stink of decaying greens and garbage was highly reminiscent of Ivy’s irresisistible gas, but of course the jester had added her own flair: the stink of grease and carbs.
Completely unaware, Harley stirred in her sleep, a few fingers reaching down to scratch her buttcrack. The red and black crease between her shapely ass taunted the master thief, enticing her to come closer for a sniff. She resisted, knowing that if she dove in, there was no telling how she would get herself out.
FFFFRRRRAAAARRRRRLLLLT
…Unfortunately for her, Harley’s ass was very persuasive.
FFFFFRRRRRMmmmmmmmmMMRMRRRRRAARRRRRT
Partway through her next fart, Catwoman dove in, a modicum of her natural stealth and dexterity being deployed to keep Harley asleep. Her face pushed gently against her rancorous ass, muffling the sound briefly before it reasserted its dominance by escalating its gas even further. Catwoman felt her mind all but give out, offering much less resistance this time than with Ivy. Her sniffing grew more frantic, desperate to suck in all the delicious stench that Harley’s bubbly ass was delivering into the tight space. Never satisfied, Catwoman plunged her face deeper between her cheeks.
“Wha…”
Harley woke with a start, feeling a strange new sensation at her backdoor. “Who…wh…” She stopped to rub her eyes, her senses also obviously dulled. “Catwoman?”
A more lucid Catwoman would have stopped and said something, but she was currently too busy huffing out every last particle of Harley’s gas. “Mmmmhhh…”
“What are you—What is—Ooh!”
GGGGRRGRRRRRRrrrrrraaaaAAAAARRRRT
Harley keeled over as she felt a particularly large gas bubble push out of her lower gut. Her adjusted posture meant that her ass was no longer in firm contact with Catwoman’s face, leaving the gas to fumigate their pod.
“Gah, why am I so…so…” Harley’s eyes started glazing over, with hardly a chance to regain her senses. “Gassy…” The stink of her own farts attacked her nose, and her resolve weakened.
Catwoman, meanwhile, was already repositioning herself to move closer to Harley’s round butt, even pushing her over as she did so. The two women grappled lightly, their strength sapped and their focus battered by toxin. Neither could particularly tell what was going on.
When the scuffle ended, Harley Quinn found herself folded with her ass in the air, and Catwoman was practically drilling her nose as deep into the crevice as she could get it. Before any farts could be released, however, the flower pod began to stir around them.
FFFFRRRRSSSSSSssssssssssssssssshhh
“Ohhhh…”
A surprisingly loud hissing sound came from above, followed by a punctuating moan. The two looked up to see the tips of the flower pod opening up above them, and as the leaves parted, a familiar green butt appeared to sit atop. The same stink of rotting plants filtered into their pod as Catwoman and Harley put two and two together. They both began frantically sniffing Ivy’s ruthless SBD, savoring every ounce they could. There was of course more than enough, as the pod had easily filled up with the dense gas.
“Mmm.” The pod opened the rest of the way to reveal Ivy hovering above them on a large leaf. “Well, good morning, ladies. I see you’re already enjoying each other’s company.” Ivy rose from her seat as she was gently carried down to the floor to greet her captives. In her hand was a small vial, filled with a translucent liquid.
Catwoman, still in her dazed, horny state, stumbled towards Ivy in a misguided attempt to get to her rear and begin sniffing. Ivy pushed her aside with ease. “Ah-ah, Selina. That’s not what I’m here for. I’m merely here to give you some medicine.”
“M-m-medicine?”
“Mmm.” Ivy proffered the vial in her hand. “Drink this.”
Catwoman squinted at her, uncertain as to what the hell this stupid glass thing had to do with her goal: sniffing as much gas as possible. “Why?”
Ivy sighed. “Drink this and I’ll give you another dose of my gas.”
That was all she needed. Without another word, she grabbed it and downed the vial’s contents.
Meanwhile, Harley observed this interaction, the pieces slowly drifting into place in her mind like flotsam in a foggy sea. The vial looked exactly like the vial she was tricked into drinking when she arrived at Ivy’s place a few days prior. How many days was that? What had happened since then? Best she could remember was she had been in that flower pod for most of it. Right? Oh, and she was super gassy all the time now, too. And…oh, right. Pheromones or whatever. She had been furiously masturbating to the scent of her own farts for a few days straight.
A more lucid Harley Quinn might have been mortified at that realization, but right now, she didn’t care about that.
FFRRRRRRSSSSSSSHHHT
Instead, she watched with seething jealousy as Ivy delivered another savory fart point-blank for Catwoman, as promised.
“Now, get back in your pod, both of you,” Ivy commanded, before adding, “and I will reward you with another dose."
The two women obliged. True to her word, just before the pod sealed up completely, Ivy climbed atop it, taking her seat. She chuckled. “That’s right, give into my overwhelming toxic gas. Your minds belong to me now...me and my powerful rear.”
FRRRAAAARRRRSSSSSSSHHH
PPPPRRRRRRMMMMRRRRRRT
BBBRRRRRRRRRRAAAAARRRRRT
A sequence of eye-watering farts blew out of Ivy and into the sealed pod below, again demonstrating her gaseous prowess. The three massive farts were only the beginning, as Ivy’s floodgates were now open after nearly a full day of storing up her gas for her dear prisoners.
BBRRRRRRRAARRRRLLLT
FFRRRRRRRFFRRRRRRTT
BBRRRRRMMMMMFFffsssss
ssssSSSSSSSSSHHHT
“Mmmhhh…Oh, Red, that’s amazing…” Ivy heard Harley say under her. Yet not a peep from Catwoman. Ivy peeked between her thighs to see what was happening.
What she saw first was Harley Quinn already in a state of undress, peeling off her outfit to reveal a pair of gorgeous breasts. They glistened in the dim light with perspiration, but cooling off her well-endowed chest was clearly not Harley’s main goal. She was eagerly undoing the buckles and straps on her pants and belt; as Ivy watched, she plunged her hand hungrily between her own thighs and began rubbing her pulsating clit.
“Ooh, yes, Red, give me some more of your juicy toxin farts,” Harley breathed, her hand already picking up the pace. Her other hand began drifting to her supple breasts, toying with a nipple as she shut her eyes in the early moments of ecstasy.
Just behind Harley Quinn, however, was Catwoman, bent over on her knees. While her pod-mate was obliviously masturbating, Catwoman appeared to be in abdominal pain. Of course, Ivy knew what was to come.
“How are you doing down there, Selina?”
Catwoman did not respond…but her back entrance certainly did.
FFWRRRRRRRRRAAARRRRRGGGGRRRRRTT
An absolute behemoth of a fart exploded out of Catwoman’s rear, briefly startling Harley. She turned to face Catwoman, a new stench filling the space. Harley could practically taste it, and somehow it was just as addictive as Ivy’s.
“Was that…was that you, Kitty-Cat?” Harley approached her, horny and disheveled with one hand still down her pants and her top completely off. Catwoman’s stink washed over her, reeking of spoiled dairy with a definitive sulfuric eggy punch. And yet that familiar note of rotting vegetables was intertwined, presumably from Ivy’s serum. “C-can you…do it again?”
Catwoman slouched over, an idle smile on her face. She had never farted at that scale before, and even if she had, she doubted it would ever bring the kind of sensual pleasure it did just now. Whatever Ivy gave her was a truly amazing substance. As the smell of her own fart slowly wafted into her nostrils, Harley’s request rang like a bell in her brain.
FFRRRRRT
“Go on, you two,” Ivy coaxed from above, adding a relatively small fart into the already hazy air. “You know you want to.”
Almost simultaneously, Harley and Catwoman responded by acting on their imminent desires: Harley lunged into Catwoman’s plushy rear, while Catwoman keeled over and braced herself to release another explosive fart. The end result was something that made Ivy’s hand drift towards her loins as she watched.
bbbbBBBBBBBRRRRAAAAAUUUURRRRRRMMMMFFFFFFFFT
“MMMmmmmhhh…ohh, Selina…!”
This fart raged on and on against Harley’s face, beating out Catwoman’s first one in nearly every regard. The eggy stink overwhelmed Harley almost immediately, and her hand found her pussy within the first few seconds. She couldn’t help but moan out against Catwoman’s gorgeous buttocks, though she was quite muffled and drowned out by the erotic gas expulsion.
Catwoman found even greater pleasure in releasing such a monstrous fart, and the gurgling in her stomach told her that there would be plenty more to come.
GGRGRRRRRRRRRAAARRRPPP
Before Catwoman could unleash another blast, however, Harley beat her to the punch. She turned to stare at Harley, suddenly eager to sniff her farts as much as she wanted to push out her own. Her fart-addicted mind struggled to resolve her competing interests, and she hesitated briefly before lunging at Harley to turn her on her stomach and plant her nose on her butthole.
GGRRRAAAARRRRPRRPRRRRSSSRRRRT
“Mmmm, Harley, you need to take these pants off…”
Harley giggled. “Why don’t ya help me with 'em?”
As they began fondling and further undressing each other, Ivy descended from her seat, the pod sealing up the window above. It was time for her to take a more direct role in this. By this point, a truly fearsome miasma of the three women’s enhanced gases filled the small flower pod. The final sealing of the pod as Ivy came down hardly made a noticeable difference with what gas was currently trapped inside, but she knew that the night had only just begun.
With some further coaxing and commanding, Ivy managed to line up the three of them together in a satisfying arrangement.
“Oohh, you are quite the eager sniffer, Selina…”
From her seat atop Catwoman’s face, Ivy was rubbing herself gently, not wanting to get too carried away too quickly. She measured out her brutal farts in a similar fashion.
BRRRRRRRRMMMMMMMMMRMRRRRRTT
PRPRPRRRRRRRAAARRRRGGRRRT
Well…somewhat.
BBRRRRRRRAARRRRLLLT
Ivy’s oppressive stench, heavy with the smell of rotting garbage, was deposited directly into Selina’s nose and mouth.
“Mmmmphh…”
“Oh?” Ivy could feel Catwoman slowing her breathing against her puckering hole. “You better not be fading on me again, Selina. Harley, keep her awake, please…”
Harley was doing her best. Any time Catwoman seemed to be losing consciousness against Ivy’s point-blank bombardment, it was her job to press into her pussy with her tongue, deftly working her magic.
“Come on, Kitty…We’ve still got so much in store for ya…”
“MRMMMPH!”
FFRRRRRSsssssshhhh
As soon as she felt her seat restored under her, Ivy resumed her gassing.
“Gaahh…”
Catwoman, meanwhile, was busy trying not to lose her mind from the sheer orgasmic pleasure. In her face was a near-constant stream of Ivy’s addictive farts, causing her clit to throb with ecstasy at every turn. Though she had been brought to the brink of unconsciousness numerous times from Ivy’s relentless fumigating of the inside of her head, she began to find a delirious sensation in being toyed with like this. And of course, with Harley nestled right against her volatile backside, she could relieve herself freely as well, her newfound gassy talents surely not going to waste.
PPRRRRRRRAAARRRRMMMMMFFT
“Hnnaaahh, do that again, Kitty-Cat, my mouth was closed…”
BBBRRRRRRRAAAARRRRLLLT
“Mmmm…delicious…”
