Kali's Gift
by QicenoQ

May 24th, 2019



Dylan laid in his bed & idly stared at the ceiling. His 18th birthday was today, and he made sure nobody knew about it. He didn't feel right being acknowledged.

He considered himself a lowly degenerate. Years of basically-unrestricted internet access found him stumbling into some rabbit-holes, and he fell down a pretty gross one.

It culminated in him getting a fart-fetish, which he hated. It affected his life pretty badly. He felt awkward around any girl that passed him due to his odd fascination.

His kink wasn't helped by his older stepsister, Kali, who was a very gassy girl.

He first met Kali three years ago when their parents met; his dad & her mom got engaged in no-time, and they soon moved in together.

They were almost the same age; she was just a month older than him, but it wasn't obvious. Dylan was fairly tall & skinny, and his constant scowl made him look older. Meanwhile, Kali was a chubby short-stack with clear skin; accentuated by her alt getup. Her black, silky hair was pretty unique in their area, making her look like a pudgy scene-girl after she put on her round-rimmed glasses.

They weren't that close though due to Dylan's bitter disposition, but he didn't dislike her either. Kali was kind of bratty sometimes, but mostly too introverted to be a nuisance.

Her gas was another entity, however. It got so bad that Dylan's dad had enforced a new diet for Kali to prevent her from clearing the entire house.

Dylan felt pretty bad for her. She was already super shy about her gas, and was left out a lot because of her newfound inability to enjoy different kinds of foods.

The worst part to Dylan was that he was a hardcore eproctophile, yet he never smelled one of Kali's supposedly-toxic farts. The fact that he envied others' suffering from his step-sisters gas made him feel like a scumbag.


It was his birthday, Friday, yet he didn't celebrate. The only gift was his dad & stepmom going on a long holiday across the country to celebrate their anniversary, leaving the house to himself basically. That, and a text from both of them. That was more than he wanted, but he accepted it regardless.

*SLAM*

Dylan then jumped as the front door slammed from the living room. He worriedly slid out of bed & left his room to investigate.

He looked in the living room to see his step-sister laying on the couch, wearing a pair of jeans & a black hoodie. But more notably, the sound of her sobbing filled the room. It was as deafening as it was unfamiliar, and he dropped the annoyed expression quickly.

"Woah woah, Kali? What's wrong?" He walked in. She looked up at him; her makeup ran down her face as she tried to compose herself.
"A-Are you okay?"

"N-No.." She said, sniffing a bit. Her lip quivered as Dylan approached her. "It- *sniff* It's nothing, Dylan. Don't worry about it."

"It doesn't seem like nothing.." Dylan hummed as he sat next to her. Seeing her cry put him on edge.
"What's up?"

"Ugh- Dylan, seriously." She furrowed her eyebrows at him. "Don't try to care just because you saw me cry. I thought you were working today.. I thought I was alone."

"I wanted to." Dylan then hummed. "They just wouldn't let me since it's my birthday."

"... It's your birthday?" Kali asked. "They never said your name over the intercom this morning, though..."

"I told them not to." Dylan revealed her ploy that day. Kali looked at him with a confused expression. He felt tense as he turned back to the hall.
"W-Well, I'll leave you alone if you want."

"Wait- no.." Kali beckoned him. "Why'd you tell them not to?"

"... I don't want to talk about it." He then stated, before trying to stand up. But he felt a grip on his wrist; Kali grabbed him.
"What?"

"You can't just say that, then walk away." She huffed. Dylan annoyedly sat down as she kept him anchored.
"... Can we vent to each other?"

Dylan felt scared by her offer. Her troubles, in his mind, were probably something he couldn't comprehend; maybe something to do with her friend Amber. Meanwhile, he had a full folder of stuff that even a therapist would judge him hard for.

"I don't know..." He answered, showing more reluctance than ever before.

"It can't be that bad.." She then smiled, wiping away some tears as he leaned into the backrest.
"I'll go first, okay?"

"Okay then." He gave in.

Kali sighed a bit as she leaned into the backrest as well. The two faced the powered-off TV, listening to the white-noise as she composed herself.

"... I made Amber throw up on the ride home."

"... What?" Dylan turned to her. "Jesus- how did you do that?"

"Well... Y'know how your dad banned me from eating pizza too?" She bitterly asked, getting a nod in response.
"Right... Amber kinda made me eat a few slices. I was apparently complaining too much about my diet, so... I had some garlic-crust supreme pizza. And... I farted in the car."

Dylan could only nod, but his eyes widened as he pictured it. He remembered when Kali made his dad sick after crop-dusting the bathroom one morning. Part of his degenerate-self really wanted to get a noseful, but seeing his dad hunch over the toilet scared him too much. That was the first time he had seen his father cry.

Meanwhile, Kali's friend was trapped in a moving car with one.

"... Is that all?" Dylan responded. His envy grew with his awkward smile. Kali turned to him with furrowed eyebrows.
"I-I mean- I'm sorry, Kali. That's unfortunate. Is Amber mad at you?"

"Well, she wasn't happy, but she accepted my apologies." She said, "... I just hate that I can't eat anything without making everyone else suffer... It's like I'm cursed. I hate it..."

"I know." Dylan sympathized with her. "You should be allowed to eat whatever you want. I think my dad is just weak."

"Don't test that.." Kali said with a smirk. Dylan shook his head, smiling slightly.
"Ugh- I'm actually so gassy still... Who knew two slices would make me bloat so much.."

"D-Do you want me to leave?" Dylan then asked. Kali smirked at him before shaking her head.

"No, actually. You have to tell me why you're so bummed out now."

Dylan then froze up as she stared at him. He definitely didn't want to tell her anything; him being self-conscious about his love of farts, while she was self-conscious about her farts.

"... I won't judge." She hummed, making him turn to her. "It honestly felt good venting to you. I promise; I won't hold anything against you."

"... I don't know about that." Dylan then responded. Kali groaned before sliding closer. She then grabbed his wrist again.

"I have ways of making you talk." She growled in a tiz manner. Despite the bulk she had on him, her grip was tight enough to make her look like a pushover.
"Talk, or I'll fart."

"O-Okay.." He felt an odd sensation rush through him after hearing her say that, only making him stumble on his words even more.
"... I... I have a kink.."

His beginning statement made her tilt her head. Dylan's heart pounded as he told someone his secret.

"... Okay?" Kali replied. "It's a kink... u-unless it's like- illegal, there's nothing wrong with it..."

"R-Right.." Dylan shuddered slightly as his step-sister kept her grip on his wrist. With another sigh, he bit the bullet.
"... It's a fart kink, Kali."

"..." Kali pulled away & stared at him. Her dull reaction was almost disturbingly underwhelming to Dylan.

"I hate myself for it." He continued. "I've had it for years, and it's been a hindrance.."

"Oh.." Kali then hummed. "... W-Well, yeah. That's definitely a shock.."

"I'm sorry, Kali." Dylan then murmured, rubbing his eyes. "I also feel like I’m cursed, if that’s any consolation.”

“How is it a hindrance?” She then asked. “Do you feel awkward around others like me?”

“Basically, yeah.” Dylan answered. “... I wish I could just get rid of it.”

“That’s not a healthy mindset..” Kali retorted. “That’s a part of who you are. At this point, you should just own it..”

“I wish it were that simple.” Dylan then paused after truly venting to his step-sister. Her sitting next to him made the atmosphere awkward.


“... Okay, well… how would you get rid of it?” Kali asked. “I mean- I don’t think it’s possible, but… as your older sister, I’m inclined to help.”

“...” Dylan felt his heart-rate grow as a plan formed in his head. It was an idea he had created in the past, but never thought it was possible to act on it.
“... You shouldn’t, Kali..”

“No, seriously dude. Tell me..” She squeezed his arm tighter. “Just- how would you go about getting rid of it? I already know you have an idea, so just tell me.”

Dylan took a breath.

“... Okay… It’s a form of exposure therapy. But like-... extreme.” He elaborated. Kali nodded.
“If someone tortured me with their gas, I would be too… traumatized… to enjoy it.”

“Oh- oh…” Kali hummed. “Yeesh…”

“Yeah..” Dylan sucked his teeth in. “I was thinking of paying some girl to fart in my face on my birthday. Now… I guess I just need to find one?”

“Ugh- Dylan, no..” Kali shook her head. “You don’t need some other girl for that. I know it’s gross, and I think it is too, but… c-could you pay me to do it?”

Dylan’s heart sank after hearing that. Kali only looked at him expectantly.

“A-Are you sure?” He asked. Kali blushed slightly.

“O-Only if you pay me.” She answered. “How much do you have? I’ll use some of it to make it worse for you.”

Dylan was baffled by how willing she was to help him with his experiment. It definitely helped knowing he wouldn’t have to ask around for some random chick to do it.

“... Seven-hundred & fifty dollars.”

“WHAT?!” Kali asked with wide eyes. “Where did you get that kind of money?!”

“I pocket fifty dollars from every payout. Under-the-table has that perk.” He answered. Their parents were fairly strict with their money; they had to ask before making every purchase.

“Oh my god..” Kali was shocked. “A-And you’ll pay me that?”

“Only if you agree to something.” Dylan replied. “Just to make sure it’s as bad as possible.”

“O-Okay?”

“We have to do it every day until mom & dad get back, and you have to make it as difficult for me as you can.”

“Uhm… Are you sure?” She asked. Dylan nodded.

Kali’s face screwed up for a moment, but she sighed & nodded.

“Fine, but I have a rule of my own.” She responded. “I get to buy a new webcam & record our sessions. And if you deny a session, I’ll show it to Amber.”

“O-Oh, wow. Blackmail?” Dylan’s words made her grin. Seeing that actually made him feel better compared to her crying prior, even if the reason for her uplifted mood was pretty weird.
“I mean- fine, I agree.”

“Cool.~” She then stood up. “Let’s go to Best Buy. Then Taco Bell. Then… wherever sells rope & tape.”



…


…


Dylan felt tense as he & his older stepsister pulled into their driveway. They spent about an hour in town, shopping with the $750 he had saved up.

He couldn’t deny that he was partially excited to see if his whole obsession was all about. He turned to Kali; she just ate a buffet of Taco Bell items that she had been banned from even talking about. Her smile was infectious.

As the car went off, Kali sighed. Just then, the silence between them was interrupted by a monstrous gurgling noise from her stomach. She looked down, then turned to him.

“I have to fart.” She said with an uncomfortable smile. “I hope you’re ready to be tied down & gassed.”


They walked inside & into Kali’s bedroom. Dylan slid onto her bed while she pulled a box out of her shopping bag; a new, expensive webcam. Dylan knew she made YouTube videos & wanted something more professional, so that purchase added onto his good-brother points; at least to him.

Kali smiled the entire time she set it up. Then, as the camera connected to her computer, her jaw dropped.

“Oh my god- It looks so good..” She turned to her younger step-brother with a quivering smile.
“Thank you- thank you- thank you..”

“It’s nothing, Kali.” He answered. Kali nodded.

“Should I start the video & explain what we’re doing?” She asked. Dylan nodded.

Kali took a deep breath as her mouse hovered over the camera icon. She then clicked.

“H-Hey everyone. O-Or- whoever sees this.” She began awkwardly. “So, my younger step-bro has a fart-fetish. And he wants to see if I can break it so he no longer has it.”

She turned back to him.

“You’re going to let me tie you up & fart in your face. And if you don’t let me do it until our parents get back, I get to share the footage of me humiliating you. Are you sure you’re okay with that?”

“Y-Yes.” Dylan answered. Kali looked unconfident with his wishes, even now. But she was too deep in.

Kali stood up & reached into her shopping bag before pulling out a roll of duct tape. She ripped a long strip out before approaching.

Dylan let her tie his arms behind his back, then to his legs. She then covered his mouth before pushing him onto the bed. He fell, helplessly unable to sit back up. Kali giggled before grabbing him, pulling him onto his stomach.

Dylan then watched something that he could only dream of before; Kali slid onto the bed as well, then backed up toward his unbudging body. Her ass grew closer to his face; she then reached back & pulled his hair, making him raise his head, then slid under it.

His face lowered once she let go, and he practically face-planted with her jean-clad butt. Her smiling back at him over her shoulder made him shudder.

Kali then arched her hips up, making him raise as well. She pulled a belt out of her bag, then slid it under her hips before lowering down. Dylan then felt it drape over the back of his neck; Kali grabbed the other end & latched them together before pulling tight.

Dylan felt the pressure grow harsh on the back of his neck, but in turn, his nose pressed tighter and tighter against Kali’s butt.

The motion in the bed rubbed against his crotch, and with the scenario at hand, made Dylan erect. His current pose made it uncomfortable, but he already wanted to explode. He tried not to sniff to avoid freaking out his older step-sister, but he couldn’t help it; he took as quiet of a breath as he could. But thanks to bad sinuses, he couldn’t get much.

“Mph- there.” Kali said after tightening the belt as far as it would go. Dylan’s face was basically fused to her ass. She shook her hips to prove that, dragging his head side-to-side with minimal effort.
“Okay, I’ve been dying to fart for the past 20 minutes.”

Dylan felt anxious as she turned away, then pulled her phone out. He was in the most dangerous zone of the house, and he couldn’t be happier. But with that, he hoped this would work.


Pbrrrrrrrrbrrrrrrrrrrrrrpht


Kali cringed after pushing a bassy fart out. Dylan felt the fabric around his face grow feverishly warm, before a simply putrid stench flooded his nose. He expected it to be bad, and took another sniff to fuel his desires.

But it was too much. Dylan tried to turn his head, but Kali’s belt prevented him from even budging.


Broooooooooooooooooorpt


Another long fart puffed entirely up his nose. Dylan jerked his taped arms to possibly free them, but it was fruitless. Their session had just begun, and he was already hating it too much.

“He’s struggling a lot.” Kali addressed the camera, acknowledging her brother’s regret.
“He should’ve thought twice before letting me fill up on Taco Bell.”


Prooooooooooooorbbbt


She was firing off some of the most nauseating farts he’d ever smelled in quick succession. Dylan broke out in a fit of coughs finally, unable to stomach his own request for torture.


Pvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvmmpt…


“MMMMMPH!” Dylan screamed from her latest emission; a burning hot stream of fetid gas that continued for several seconds. Kali looked over her shoulder.

“Are you okay?” She asked. “I’m sorry for that one..”

“MMMPH! MMMMPH!” He tried to shake his head again, once again unable to.


Kali began to wonder if this was too much, but Dylan had asked her to go as hard as she could. She decided against letting him out, fearing that he would be mad at her for going against his instructions.


Broorbbbbbbbbbbpt


Groorrrrrrrrbt


Brrrrrrrrrrrrrrrrrrrrrpht…


Prrrrrrrrmp


Ffffffffmp…



Kali continued berating her step-brother with farts. And surprisingly, she felt her worries waning; it felt good to eat what she wanted, then let her most foul farts out. But on top of that, she had someone to sniff them; let alone, someone who asked her to let him.

Meanwhile, Dylan was suffering. Every fart made him gag, and regret set in hard as he felt every one light up his nose. Her gas was so much worse than he had fantasized.


Prrrbrrrrrrrbrrrrrrrrrbrrrrrrpt…


Kali scrolled through her phone as she casually farted up her brother’s nose. Her latest emission made Dylan cry; but instead of showing any concern, she only puffed her cheeks up again.


Bbrrbrrrrooooooooooort


Dylan gagged again on her horrific gas. The onslaught became so bad that he inevitably threw up in his mouth, but it had nowhere to go thanks to the tape.

“Did you just puke?” Kali asked. “I’ll let you go if so.”

“MMMPPH!” Dylan nodded to the best of his abilities, thankful that she was finally done.

“Pff- no, I can’t.” She then cruelly followed. “I have to torture you until I’m gassed out, remember?”

“Nmmph…” Dylan whined as he accepted his defeat. He couldn’t even be too mad; he asked for this, and it was already a miracle that she went along with it in the first place.


Ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff…


Suddenly, as if it couldn’t get worse, Kali’s butt grew insanely hot as she pushed out a long, dense SBD that continued for several seconds. Dylan screamed as the cindering stench of digested spices & hot sauce burned the inside of his nose.

That fart was so bad that it made him vomit again; this time so much that he felt it trickle out of his nose. He was forced to swallow it, but the liquid blocking his nostrils prevented him from breathing.

“Mmmmph! Mmph- mmph!” He tried to tell her that he was in danger, but she only took it as more ‘insignificant’ complaining. Dylan cried as he feared being smothered, but realized he had a way to unclog his nose.

He took a deep sniff, making the inside of his nose gurgle as he snorted his own vomit. But at the same time-


Bbrrrrrrrrrbbpt


Kali farted again. He sniffed it in its entirety, and almost immediately got sick again. He really began to break down as every recent fart made him puke.


Bwooooooooooort


Pffffffffffffffffffff…


Phhfffffssssssssssss…


Prrrrfffffffffffffffffff…


Brrbrrbrrrrbrrrbrrrrrt


Grrrr… rrrRRRBT!



…


…


The clock ticked as Kali continued to torture Dylan with her farts. But eventually, her tank was running empty.


Prrt


Rrrbt


Bloorpt


She looked back at him over her shoulder; his tears were running down onto her jeans, leaving stains. He looked exhausted.


After over 2 grueling hours, Dylan felt the pressure on the back of his neck alleviate. Kali undid the belt, and as soon as he processed it, he began to pull away from her ass vigorously.

His nose was finally separated from her jean-clad butt, and he began to hack as the hours-worth of gas in his lungs battled with the fresh air outside.

He slid off the bed & covered his mouth before dunking his head into her garbage can, then began to profusely vomit. He had swallowed his own bile so many times that he couldn’t even count it.

Meanwhile, Kali slid off the bed & turned the camera off. Over 2 hours of footage occupied her once-empty flash drive, and she pulled it out before pocketing it.

Dylan picked his head out of her trash can & looked up at her with bloodshot eyes.

“Same time tomorrow?” She asked.

“W… W-What?” Dylan asked with a shaky voice. “A-After all t-that?”

“You said ‘every day’.” She reminded him. “I’m thinking… Chinese food tomorrow.”

“K-Kali, no..” Dylan felt like crying just from thinking about it. His older step-sister looked at him with a pitiful expression.

“Sorry, then I’ll have to share this footage with Amber.” She slapped her pocket. “I’m sorry to have to do that to you, but your fear of my butt now proves your idea works, and I would be a bad older sister for not helping you.”


Dylan couldn’t believe how dead-set she was. But she was right, and they only had about 4 more days of this until their parents returned.

Begrudgingly, he nodded.

“So again- Chinese food.” She repeated, then slid into her bed before laying on her back.
“And can you change the garbage bag? Thank you..”


May 25th, 2019



Kali laid on the couch, enjoying her weekend by lazing in her comfiest pair of grey sweatpants & a baggy hoodie. Her wallet was still full of money, and she had just spent some of it on Chinese food; something she was also banned from eating.

Part of her still felt bad for Dylan. Even if it was his idea for her to torture him in hopes of breaking his attraction to farts, she knew what her bowels were capable of. She spent that entire morning thinking about how tightly his nose was pressed to her ass while she farted & farted for over 2 hours.

But that was only part of her that felt bad for him; mostly, she loved how she could just use his nose as a receptacle for her disgusting gas. And better yet, she HAD to do it, so she had an excuse to make him. She would be forced to stop when their parents got back from their anniversary trip.

As she slurped some udon, she realized that she hadn’t seen her step-brother all day. He hadn’t left his room, and after a couple crab rangoons & fried rice, she was beginning to worry if she could hold her gas before getting to him.

She put the takeout box down before getting up & walking down the hall. His door was still closed, and the lights were off. Odd, given his knack for getting up early, and he didn’t work on Saturday.


*Knock knock*


She waited for an answer.

“... Yeah?” A voice on the other side of the door responded. Dylan sounded timid; she understood why, and knew she would have to talk him into his torture. He looked terrified of her yesterday.

“Dylan, come in here. We need to do our session.” Kali responded, and she could hear him groan from inside his room.
“Need I remind you about the video?”

“Ugh..” He whined from behind his door. “C-Coming..”

“Meet me in my room.” She said, then went back to the living room to get her food.

Her stomach growled a bit, and she knew she would be pumping out some toxic farts; Chinese food always gave her room-filling gas, and she wondered how well her younger step-brother would take them.

As she walked into her bedroom, she heard Dylan’s door click before opening. He walked out with wide, anxious eyes, and jumped a bit at the sight of her looking at him.

“Are you okay?” She asked. He didn’t answer verbally, only looking down and shaking his head.
“I’m sorry, but you know we have to do this.”

“D-Do we?” He asked. “I-I know I asked for it, b-but it’s too much.”

“We’re not doing it for fun.” Kali answered. “I can tell you’re afraid, and that’s proof enough to me that it’s working. As long as I have video proof of you agreeing to do this, I’m not going to stop until our parents get back.”

“Please..?” Dylan pleaded with her. Kali crossed her arms as she looked up at him.

“No.” Despite being shorter than him, she felt more powerful at this point. She’d never seen her angsty brother acting so skittish. It was slightly endearing, if not annoying, as her stomach was starting to growl more.
“I have to fart. Let’s go.”

Dylan looked seriously paranoid as he followed Kali back into her bedroom, approaching her bed as she closed the door behind them. As he sat on it, he watched her wake her computer up before opening the camera app.

“Again?” He asked. Kali looked at him over her shoulder as she clicked the icon to start a recording.

“We need to.” She hummed, then stood up. “More footage to incriminate you with will help me win a fight if you decide to fully break & deny more sessions with me. Now, lay on your belly.”

Dylan hated that he followed her instructions, laying flat on his stomach again as he waited for her to bind him up. Like yesterday night, she taped his arms & legs together, leaving him unable to move his limbs, then taped his mouth. She then grabbed the belt before sliding into bed, scooting back until her ass was in his face. Then, after pulling him up & sliding under his head, Dylan whined as his nose was once again between her cheeks, pressing flat against her crack.

The looser fabric of her sweatpants meant he felt his nose slide between her cheeks easier; his nose forced some of the fabric to wedge between them as well, and that only amplified as she tightened the belt. He whined again as he was once again totally helpless, destined to another long while of fart-slavery.


He then felt Kali’s stomach gurgle after she finished tightening the belt. With that, she pulled her phone out before taking another slurp of udon, and began watching videos as she snacked.

Dylan was terrified. He only heard tales of what Kali’s Chinese-food gas was capable of, and if Taco Bell was as bad as it was, then this could only be pure torture.


Brooooooooooooooooooooorpt


An airy fart then filled his nose, breaking his anticipation & replacing it with a harsh coughing-fit. It smelled horrid.


Brrrrrbrrrrrrrrrppt


“Mmph- *hrk*” Dylan gagged as another fart inflated his nostrils. He tried to shake his head out of instinct, but unlike last night, it negatively affected him this time; his nose went deeper into his ass, as his motion spread her cheeks further apart.


Poooooorpt


His nose vibrated from yet another fart. He hacked on the stench, once again unable to fathom Kali’s gastric power.

“The belt feels looser..” She then commented above. Dylan’s eyes widened as he watched her arms rear back, then tinker with the buckle. He defiantly pleaded for her to leave it alone, but she ignored him & fastened it tighter. Thanks to his accidental-nuzzling moments prior, he was now locked tighter to his older step-sister’s ass.
“There we go. Now, stay put. You aren’t going anywhere.”

“Mmmph…” He whined in defeat.


Pbbrrrrrrrrrrrrrrrrrrrrrrrpt… Prrrbrrrrrrrrrrrrrrrrrrrrrpt… Rrrrbpt


A long surge of gas attacked his nasal passage, making him gag as he was forced to bear it. His eyes began to tear up from the overpowering stench, and despite eating nothing after last night, he felt like he was going to be sick again.


Bbrrrrphhhhhhhhhh…


“Oooh..” Kali complained above before covering her mouth. Dylan couldn’t help but thrash in retaliation. That fart was unbelievably lethal.

“MMMMPH- *hrk*”

“I don’t blame you.” She said, then offered her sympathies in the most disrespectful way. “Here, I think I have another one. It might replace the smell of that last one.”

“MMMPH- MMMMMPH!” He vehemently denied her offer.


BBRRRRRRRBBBBRRRRRRRRRRRRRRRRRPHT!


But to no avail. And shockingly, this latest fart was worse by a significant amount. A lot of it was caught by her sweatpants & made the fabric super warm, as well as super stinky. Dylan was given the task of dealing with it.

“Mmph- *hrrrk*” He inevitably vomited in his mouth again before breaking down completely, crying as Kali mercilessly smothered him with her now-fetid backside. Meanwhile, she finished her bowl of udon before pulling another crab rangoon out of her takeout bag.

“I missed Chinese food.” She hummed, appeasing her stomach with another rangoon while her little step-brother suffered behind her. In her moment of euphoria, she shook her hips in a rhythmic, joyous motion that dragged his head around.


Blrrrrrpt

Broort

Rrrbbbbbpt

Proopt


Dylan’s eyes clenched shut from the bombardment of gas, squeezing his tears out onto his older step-sister’s sweatpants. Every one of them made him tense up. He was becoming genuinely scared of her farts, as opposed to just hating them like his father did.


Bwooooooorssss…


Pbbbbbbrrrph…


Brrbrrrrrrpht


Ploorbbbpt


Ssss… rrrbt


The torment continued for a while longer. Dylan was too sore to squirm now, and he felt like his brain & nose were fried. Despite that, he coughed & gagged every time she had a fart for him.


Prrrrrrrrrrrrrph


Blorrpt… Blrrrphh…


Pffffff… ssrrrrbt


Kali eventually grew bored of scrolling through her phone. She was out of food, and had basically nothing to do. But she felt more gas in her stomach.

In a moment of true cruelty, she began to wonder how badly she could affect Dylan if she tried to fart, as opposed to letting them out randomly. His head was still tightly affixed to her ass, so she could do whatever she wanted.

She lifted her hips up & began to pat her belly. Dylan whined as he knew what she was doing, and once again tried to shake his head in denial. But yet again, he only managed to bury his face deeper into her ass.

“Ooh-” She jolted, feeling his face burrow into her ass. She covered her mouth, hiding a smile from the camera.


Pffffffffffffffffffffffffffffffffffffffffffffffffffrrrrrrrsp…


After a hard push, a burning-hot SBD simmered out of her hole. Dylan felt his nose grow hotter & hotter, but he was too occupied with how unbelievably rank it smelled. In a moment of desperation, he attempted to turn his head. It didn’t matter which way he turned though; he only slid deeper into her butt.

“MMMMMPH!”

“Mh~ the belt feels loose again.” Kali shook her hips again, taunting him before rearing back & tightening the belt even more. Dylan whined as the pressure returned while his face was deeper than he had ever hoped it would be.
“There. Perfect, and I have to fart again.”

“NNMMPPH! PLMMS!” He pleaded once more, but his screaming fell on deaf ears.


Crssssssssss… Ppppppppplrrbpt


After another simmering SBD, a wet cacophony followed. The two farts smelled completely different; both reeked of pure indigestion. Dylan began to gag repeatedly before puking in his mouth again.

“Ew.” Kali commented, lowering her hips finally. She smiled as she laid her head down as well, feeling Dylan’s exhausted thrashing behind her. She committed a war-crime up his nose, and responded by lazing.

What started as a way of helping her brother break his fart fetish was slowly becoming something more for Kali. She was conflicted on whether she enjoyed it or not, but couldn’t deny that years of being denied her favorite foods, only to eat them & torture the son of the man who instilled that denial, gave her a sense of evil-power that she couldn’t help but smile at. Besides, she was still helping Dylan.


Blrrrpt… Brooooorp


She looked at Dylan over her shoulder, watching how he reacted to her farts. His eyes forced out more tears, but he didn’t cough or gag like he would with her longer farts. A playful pout formed on her face, and she closed an eye before pushing harder.


Pfssssssssssssssss…


She didn’t expect another butt-burner, but Dylan’s reaction to it was much anticipated. He dry-heaved before trying to turn his head again; the belt prevented it once more, proving its worth in making his sessions with her hellish.


With that, she laid her head back down on her arms, cushioning herself as she tortured her younger step-brother.


Brrrrr…


Rrrpbt


Brrr… phhhhhfffffffff…


Fffffffff… prooorpt


Braaaapt


Rrrpprrbpt



She felt herself dozing off; that food hit the spot, and the sensation that came from Dylan’s tossing & turning put her at ease. But she checked her phone’s clock; they had been going for nearly 3 hours.

As content as she was with taking a nap, she knew she was running out of gas.


Dylan was too exhausted to process the belt loosening at first, but the deteriorating pressure made him pull away again. He immediately covered his mouth before getting off the bed, and rushed to her door before opening it & running to the bathroom.

As Kali sat at her desk, she could hear Dylan loudly vomiting in the toilet. She looked back at the camera with a shy grin on her face, knowing the damage she had caused, before ending the video.

As it uploaded to her flashdrive, she turned back to the door to see Dylan stumbling in. His eyes were teary & bloodshot, and he had a stain on his lip.

“... K-Kali- I can’t d-do this tomorrow.” He asked. “P-Please let me have a break..”

“Ugh- we talked about this earlier, Dylan. No.” She responded. “Besides, you're done for the day. Get out of my room & go relax, or something.”

Dylan’s face screwed up before he walked out of the room. Kali was put off by his bratty behavior, but knowing it was out of pure fear made her smile.


May 26th, 2019


Dylan felt too anxious to leave his room again. He was starving, not being able to eat anything yesterday without throwing it back up. Kali’s torture was really beginning to set in; he regretted asking her to help him with ending his fetish.

On one hand, it was working. Spending hours a day with his face strapped to his step-sister’s backside made jerking off exceedingly difficult. But on the other hand, he had nothing to do now.

Meanwhile, Kali was in her bedroom, enjoying her weekend without a problem in the world.


Despite his inability to eat food, he had to try. Kali was thankfully distracted by a movie, so he opened his door & snuck down the hallway.

But Kali’s door opened.

“Okay, good. You’re up.” She stopped him. Dylan groaned as he turned to her. She was wearing a pair of jogging shorts & her hoodie from yesterday.
“I’ve been eating ice-cream. That usually gives me killer gas, and I think we can knock these next few hours out.”

“C-Can’t I eat first?” He asked, hoping to prolong his personal Hell.

“Aren’t you tired of barfing a million times a day?” She asked in response, then shook her head.
“You can eat afterward.”

“Kali, I seriously don’t think I can.” Dylan persisted, but Kali groaned.

“No, Dylan.” She huffed, then snapped her fingers. “Lay down.”

Dylan defeatedly listened to his older sister & trudged into her bedroom, then laid on her bed. Her movie on her computer was still running, but she paused it before opening the camera software.

As he sat down, he was surprised to see her plug her webcam into an extension cord, then move it to her bedside table.

“What are you doing?” He asked, looking into the lens of the miniature camera.

“Different angle.” She responded, making him even more quizzical. Mostly, as to why she would bother. As she started recording, she turned back & elaborated.
“We’re doing a different pose today, and it’ll be difficult for the camera to see your face unless I move it over here..”

“W-What do you mean?” He asked.

“I’m getting kind of sick of laying on my belly.” She said before kneeling on the bed. “Besides, I’m sure you’re sick of feeling that belt on the back of your neck. So today, I’m sitting on your face.”

“W-What?” He was scared of that. Kali wasn’t exactly fat, but she wasn’t skinny by any means. She was fairly meaty, and Dylan knew that wouldn’t feel good on his head.
“Please- can we not?”

“Sorry. I already made up my mind.” She retorted, then patted her bed, indicating that he lay down. Dylan understood, but hesitated a lot before slowly laying down.

He watched in terror as his older step-sister crawled over to him, then swung her leg over his torso. She reverse-straddled him, sitting on his chest for a moment before scooting back.

He began to panic & shook his head with denial, but she couldn’t see his silent plea.

Dylan tensed up as he let Kali sit on his face. Having his face sat on was once a dream; let alone, by Kali. But now, he didn’t want to experience it whatsoever.

Dylan’s face practically sunk into her ass thanks to her weight. She slid her legs up onto his body, sitting full-weight.

Whereas he could breathe before, he was totally unable to catch a breath; there was just too much blocking his airways.


Gbbrrrrrrrrrrrrrrrppt


As if his dark, warm Hell wasn’t bad enough, a bassy fart bursted into his nose & immediately purged any clean air he had before. It smelled like pure rotten dairy, and was bad enough to immediately make him cough his lungs out.


Prrrrphhhhhhhhhhhhh…


Another fart hissed out of Kali’s colon, and was easily worse than the last. Dylan gagged before trying to push her off with his free arms. But she didn’t even budge; instead, she acknowledged his efforts by grabbing his arms.

“Stop fighting.” She instructed. “You’re staying down there & smelling my farts.”

“MMMMPH!” Dylan couldn’t breathe, and all the air he was getting was so bad that, if he had anything in his stomach, he would’ve surely spat it by now. And it hadn’t even been a full minute yet.


BBRRRRRRRPHHHHHHHHhhhhh…


Another bassy emission turned into a silent, airy hiss, and all of it funneled directly into Dylan’s lungs. He began to thrash under her weight, but his head remained anchored to her pillow.


Pprrbbbbbrrrrrrbbrpt


Bbbbbbbbbbbbbbrrr…


Proooooorrppffffff…


Dylan hacked on basically every fart she pushed out. They were somehow worse than her Chinese-food farts, all burning with a torturous stench. How she was able to commit this level of evil on her own step-sibling was beyond him.


Ffffffffffffffffffffffffffffffffffff…


It was already bad enough, but once a proper SBD hissed out, he knew he had to fight her. He jerked on his arms that were still in her grasp & drilled his heels into her bed in an attempt to bear it. But Kali still didn’t budge.

“Those silent ones are nasty, aren’t they?” She asked him as he screamed in response.


Fffffffffffffffffffffffffffff…


She answered his rampage with another SBD. His screaming turned into an exhausted sob; they were just getting started, yet he was already breaking down.

“Jeez, are my ice-cream farts that bad? I thought my Chinese-food ones would kill you.” She then shook her hips tauntingly. That motion somehow made Dylan’s face sink deeper; his nose pressed deeply between her cheeks.
“Uh-oh. I have another one. Pray that it’s not a silent one.~”


Ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff…


She then proceeded to not only unleash yet another SBD, but her worst one yet. Dylan was too tired to thrash anymore, and took the entire burning bout of gas. His crying grew more aggressive, only being interrupted by his own dry-heaving. He surely would’ve vomited by now if he had eaten before this.


Blrrrrrmpt


Pffffffff… ssssss…


Pffffssrrrrrrpt


Rrrrrbbbpt


Kali sat on his face a while longer & continued farting. The camera couldn’t catch her face, so she smiled without guilt. This whole experiment was becoming increasingly fun for her.


Bwooooormpt…


Every time she farted, her little step-brother would react negatively; whether it be squirming, retching, or crying, she began to have fun invoking this suffering on someone. Years of being self-conscious about her own gas turned into a cathartic appreciation for how much torture she could inflict onto someone with it.


Blrrmptch


“Ooh..” Kali cringed after a particularly wet fart gurgled up Dylan’s nose. As if he hadn’t fought to escape enough, it seemed this one was the breaking point. He tugged on his arms a few times, but Kali kept a firm grip on him.

So when that didn’t work, he resorted to clawing her legs with his fingernails.

“OW-” Kali wailed before jerking his arms away from her legs. “Don’t fucking scratch me!”

“MMMMMPH! MMMMMMMMPH! MMMMPH!”

“SHUT THE FUCK UP.” She yelled back, bouncing up before coming down onto his face hard. He screamed again from the pain, but stopped soon after.
“Ugh- you just scratched the shit out of me…”


Bbrrrrrrmpt… Bloorpt


“Take that.” She then huffed with a smirk. Dylan’s crying returned, once again accepting defeat. These sessions were worse than torture.


Brrrsssss…



Gwooorpt



Brrrrrph..



Rrrpt



Pfffffff…



Ssssrrrpt



Bwooorp



Pfffff… rrrbt


Kali scrolled on her phone as she ‘helped’ Dylan, and she continued farting on him for a long time. She eventually noticed how much time had passed; 38 minutes. She ate an entire tub of ice-cream and still felt plenty gassy.

Meanwhile, Dylan was gone. He was no longer fighting her, or tugging for his arms back after every fart.

“... Dylan?” She asked. But no answer.

Scared, she sat up & looked back. His eyes looked teary & he was still, and her heart sank as she wondered if he was okay. But the sound of him snoring made her sigh a breath of relief.

He had her worried sick for a second, and she began to realize just how insane 30+ minutes of full-weight facesitting was. He was a trooper for being able to fight for so long.

But at the same time, she felt bitter that he had passed out. He never fainted before, and they got up to 3 hours yesterday.

Agitated, she waited for him to take a breath in.


Brrrrrrpht


She watched him suck that fart up. Even if he was asleep, his face still screwed up before he coughed. Kali was enthralled by his reaction.


Bwrrrmmp


She did it again. And surely enough, Dylan coughed in his sleep once more.

Kali couldn’t hold back the urge to grin. Among the humor in her farts being so bad that it affects the unconscious, she wanted to play around with her unconscious brother for a bit.

She let go of his hands & slid her hands under her shorts before spreading her cheeks. She then lowered her ass again, but didn’t sit all the way down; Kali lightly straddled his head, with his nose pressing against her spread-crack.


Prrrprrrrrrrrrrrrprrrrrrprrrrrrrrrrrprrrr…


She puffed her cheeks as she pushed a long fart out. Hearing Dylan’s snoring nose huff that entire fart before breaking out into a fit of coughs invigorated her to no end. She patted her stomach before spreading again, then lowered herself once more.


Prrrpffssssssssssssssssssssssssssssssssssss… rbt


That stomach-churning prior helped conjure a truly heinous fart. She heard the SBD this time, and covered her mouth in anticipation.

Dylan snored, sniffed it up, and coughed again. But this time, he followed that up with a gag. Then a series of gagging. Kali lifted up as Dylan began to dry-heave repeatedly.

Then, to her surprise, she heard him gasp for air before coughing.

“Ugh- ugh…” He grunted, grabbing his chest & heaving the fresh-air around him. “I-Is it over..?”

“...” Kali thought about it. She literally knocked him out this time, so he probably needed a break.
“... No.”

Dylan whined as she dropped back down & laughed at his tired whimpering. Even if she just knocked him out, she was having too much fun torturing him now.


Kali smothered him for a bit longer, and she began to think about how much their dynamics had shifted; Dylan started off as a self-conscious degenerate who loved farts, while Kali was self-conscious of her own farts. And now, Dylan obviously hated them, while she began to appreciate herself a bit more. It humored her to think that she could cure a fart-fetish. But mostly, she began to wonder if she was starting to have a thing for farts herself.


Bbrrrrpht


Dylan groaned after she farted again. Kali was content with leaving him to experience it, but something came over her.

“Sniff it.” She commanded over her shoulder. “I’ll think about letting you go if you do.”

With that, Kali heard Dylan sniffing audibly below. Her smile grew after hearing his pained, disgusted reactions after each inhale.


Pffffssssss…


She pursed her lips after another SBD hissed out of her ass. Dylan coughed again, but she lowered her weight & smothered him.

“Sniff.” She commanded again. “I can do this forever.”

“Mmph…” Dylan whined before sniffing yet again. She closed her eyes & listened to his little sniffs; knowing his nose was inches away from her butthole made it so much better.



She was definitely getting off to this.



Bwrrrrrmblpt




Pbbrrrr! Prrrrrpt




Brssst… Pfffpt




Brrrrrrnt




Broooooooort




Brrbrrrbrbbbbrrbrbbbbpt… Prrrrmpt




The minutes ticked to hours once more, and Kali felt her stomach running out of things to torment Dylan with.

She sat up again; her younger step-brother turned his head & looked at the door, waiting to get up & leave.

But she had another idea.

“Face forward.” She commanded.

“Are you seriously not done yet?!” He yelled. “Please! I just want to leave!”

“And you will when I’m done with you.” She responded. Defeated, Dylan faced her ass.

Kali then lowered her hips again, sitting down once more. And like earlier, she moved her legs up onto his body. Dylan yelled underneath her as he felt the pressure on his head again.


Kali then pulled her phone out as she sat on his face, completely restricting his air again. But this time, she planned to keep him down there.


“Mmph..” He whimpered. Kali ignored him, and even grabbed his wrists again before he could try to push her off. She knew he would try.

And surely enough, he began to struggle underneath her after a minute.

“Breath.” She hummed, rubbing salt into the wound. Dylan screamed as she smothered him with her ass.



…


…


Kali finished taping Dylan’s limbs to her bed-posts; his arms & legs were strapped tightly, and he couldn’t budge if he tried. But he was still asleep, and she planned to make this session his most taxing yet.

She went back into the kitchen & looked through the freezer. Dylan’s dad kept a steady supply of frozen bean burritos, and she smiled eagerly before throwing multiple of them into the oven.

She snacked on some more ice-cream as they cooked.


The burritos eventually finished cooking; she plated them before returning to the bedroom. Dylan was still asleep.

She ate one of the burritos as she slid into bed & sat on his face, sitting the plate on the mattress, knowing he couldn’t knock it off.


Pffffffff…


Another ice-cream fueled SBD hissed into his nose. The heat alone made Kali cringe; she knew it was bad.


“Mmph-” Dylan then vocalized his disgust before breaking out in a fit of coughs. Kali kept his nose in her ass.


Sssssfffff…


Another SBD hissed out. Kali waited for her farts to wake him up again.

Her gastric capabilities were becoming apparent to her, as once again, Dylan retched himself out of unconsciousness. He caught his breath before attempting to rub his face, where he found himself bound to her bed.

“W-What the fuck?!” He yelled, attempting to pull his wrists out of their binds. He tried to kick his legs, but no luck yet again.
“What is this?!”

“I’ve decided that we’re not done.” Kali said over her shoulder, making Dylan whine again. His growing fear of her ass continued to please her.
“I think this experiment will only work if I make it worse & worse every day. So I made some burritos while you were unconscious.”

“No- please don’t..” Dylan pleaded, but that obviously fell on deaf ears. Kali popped another burrito in her mouth before sitting down again.
“Mmmph- mmph…”

Kali’s smile returned as she went back to smothering her younger step-brother. Something about it felt right; they weren’t at odds before this, but the small things he’d done over the years to annoy her felt as if they were being addressed by her tormenting him.

Then again, she was still helping him with his problem. He deserved worse.


Brrrbpt


She would need some time before her bloating returned, but she still had just enough to prevent him from getting a clean breath. And even then, her smaller farts still reeked; Dylan whimpered as soon as it came out, before being interrupted by the urge to cough. Kali felt more & more proud of her power.


Sss…


“Mmph- *hrk*” Dylan once again whined before gagging on her newest emission; a brief SBD that reintroduced the heat he had grown to detest. Kali could feel his nose poking the warmest spot of her jogging shorts.


After a bit of time, she felt a big one form in her stomach. She was ready to drop a burrito-fueled bomb, but stopped before realizing she could make it worse for him.

She reared back & grabbed her waistband before pulling her shorts down. Dylan watched in horror as a sight, once only available in his dreams, now invoked pure fear into him; Kali’s panty-clad ass. Her striped undergarments hugged her butt.

“No- NO! Please don’t-” Kali sat down halfway through Dylan’s plea. He tried to turn his head, but his nose was perfectly aligned with her crack; he was stuck, once again at her mercy.


BBBWWOOOOOOOORRPT!!!


Kali then let loose a juggernaut of a fart. The noise echoed in the room, while the entire bout of gas was streamed directly up his nose. Dylan screamed at the new stench; cheesy bean burritos with peppers, far enough into digestion that the smell made him retch. Kali didn’t even grunt after letting it out.


Bbrrrrrbrrrrrbrrrbrrrrrbrrbrrrrrbrrrrrrrrrrrbrrrrrrrrrrrrrbrrrrrrrrbrrrrrbrrrrbrrrrr…


That fart was then followed by a much longer one, once again funneled directly into his nasal passage. The thinner fabric of her panties was practically insignificant; all it did was catch a small bit of the gas for him to sniff later.

That last fart was massive, continuing for nearly 10 seconds. This time, Kali let out a moan of relief; she had channeled that one from every corner of her bowels.

Dylan thrashed & failed to escape, and for the hundredth time that day, he broke down under his step-sister. His pained crying was only interrupted by the occasional gagging.


Pvvvvoooorpt


And as an insult to injury, Kali pushed out another fart soon after, giving Dylan another thing to hack on.



Proooooooooooooooooooooooorpt



Brrr… rrrbbpt… blrrpt



Pppfffffffffffffffffffffffffffffffff…



Brrbrrbrrrrbrrrpfffffffffffffffffffffffffffff…



Blrrrpt



Brroorpt



Ssssssssssssssssss…



The session went on over 5 hours before Kali felt bored. It wasn’t a crippling boredom, but she knew he was becoming too exhausted to react to her gas, and it didn’t feel the same without him begging her to stop.

She sat up & untied his legs as he recollected his breath. As she crawled up to his arms, he turned away with tears in his eyes. He was crying again, and clearly traumatized from being facesat by a panty-clad butt for such a long time.

Kali looked down at him as she fiddled with the tape. Their relationship never went past sibling-bickering, and minus that one interaction where they vented a couple days ago, she knew that he hated her now.

That partially hurt to take in. But knowing what she had at her disposal to ruin his reputation with, she could make him do whatever she wanted. … She felt dirty, but dirty was beginning to feel better than the clean she had been set-up to be for years.


May 27th, 2019


Kali rode home with Amber after another typical Monday at school. It was thankfully the last one they would be having, as their graduation was only in a few days.

But given the weekend she had gone through, other things occupied her mind. She saw Dylan around school, and he was different. Granted, she did torture him for a chunk of the weekend, but seeing him acting so timid & quiet in public was odd.

Something else stuck with her though; she had a huge secret that not even Amber could know about. And that made her think about what she was doing; especially what she did last night. Something came over her that she didn’t anticipate; pure pleasure in tormenting Dylan. Compared to last Friday, she was a completely different person.

Part of her wondered if Dylan was okay. But another part of her argued that she was doing him a solid that no other girl would do for him. His fart fetish was definitely broken, and any time he would even try to masturbate to farts, he would just think about his older step-sister.

But with that, their parents were still not home; evident from a lack of either of their cars in the driveway.

“You’re quiet tonight, girl..” Amber acknowledged her friend’s silence. “Are you okay?”

“Yeah, I’m just kind of tired.” Kali answered.

“I bet.” Amber said with a smirk. “I thought you were especially banned from eating Indian food, by the way. But you bought like- a ton of it. I’m surprised you aren’t dead-asleep right now.”

Kali then grabbed her backpack before exiting the vehicle.
“I’ll talk more tomorrow.”

They exchanged farewells before departing; Amber pulled out of the driveway while Kali walked up the steps to her porch.


As she walked inside, she was quick to hear a door shutting. Dylan’s attempt at hiding from Kali alerted her instead. That alone strengthened her theory that she was going too hard on him.

As she sat on the couch, she grabbed the waistband of her jean shorts & tugged it away from her body. All the eating she had been doing since Friday caught up to her; her shorts felt tighter, and the otherwise-loose hoodie felt clingier than usual.

She was once self conscious about her weight. But over the last couple days, she couldn’t help but enjoy her own presence more than before. She smiled as she leaned against the backrest of the couch, snuggling into the cushion & letting her body relax for the first time that day. She practically melted into the couch.

Kali then thought about hearing Dylan’s door close as soon as she got home. He was truly scared of her now. Fair, given how ruthless she was last night. And considering what demons were brewing in her stomach now, this may just be the last night she gasses him.

She knew Dylan would be difficult, and anticipated another reminder at his expense as she walked toward his door.

*Knock knock*

“Please- Kali, I can’t do it tonight.” He immediately answered.

“We have to, Dylan.” Kali retorted. “C’mon, it won’t be as long as last night. I promise.”

“C-Can I please just have one break?” Dylan begged. “O-Okay, I was right about my plan working. And your gas is so bad that I can’t even begin to elaborate. I-I don’t have a fart fetish anymore, I haven’t even tried jerking off to it in days! You were right to be so hesitant..”

Kali didn’t know where to start with his response. He spilled his guts out of desperation, and her guilt welled up, knowing just how desperate he was to keep his face out of her ass.

But at the same time, she had eaten too much to give him a break tonight.

“... I’ll stop doing it after tonight.” She began. “I know how difficult it is for you, Dylan. And I believe that I broke your fetish. But I already ate so much food earlier, and if we do one more session tonight, I guarantee that it’ll break your fart-fetish for absolute good. But after tonight, I won’t even let you look at my butt anymore.”

Dylan didn’t respond for a bit, and Kali waited in anticipation for an answer.

Suddenly, his door opened. He hid behind it, but looked down at her.

“... Promise?” He asked. Kali hesitated, but she knew she had gone far enough.

“I promise.”


…


…


Dylan felt tense as he let Kali tie him up to her bed again; the tape around his wrists & ankles made him shudder, reminding him of last night. He hated that he asked her to do it every night, but was happy to hear her promise the end. Plus, she opted out of recording it tonight.

That didn't excuse the fact that he still had tonight to get through. He looked down to see Kali’s butt packed in jean-shorts. Knowing that would be smothering him in a bit scared him.

Kali eventually finished. She turned to Dylan’s terrified face; she now felt worse about seeing it than she did last night. The contrast from the excitement he held on Friday night was staggering.


Kali backed up toward Dylan’s face, then lowered her hips. She felt his nose between her cheeks again, but the coarse denim made it harder to feel.

Her stomach was bursting at the seams. Indian food was something that she was ESPECIALLY banned from eating, and even she had to agree that it was damaging to her bowels. Whatever she was about to let out would probably contend for her worst farts ever.


Pppppprroooooooooopt


She leaned back to make sure Dylan wouldn’t pull away, and that was for the best. Despite being taped by each limb, Dylan practically bounced off the bed for a moment. He screamed as his nose was crammed against her ass, trapped with an absolutely lethal fart. It burned on its way out, and burned even more on its way into his nose.

“MMMMMMMMMMMPH!” He fought for his life, and it was just the first fart of the night. Kali fought to keep his head in there, and she could tell his nose would be raw by the end of tonight.


Pfffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff…


Kali’s eyes rolled back as a killer SBD seared her butthole. It continued for nearly 8 seconds, and Dylan fought the entire time that it entered his nose.

He then broke out in a fit of gagging, unable to truly fathom the demon that Kali had just pushed out. Even she was taken aback by how bad it was. Her anus was literally hurting after it ended.

She was sort of hesitant to fart again. Dylan was still squirming under her, and he even vomited soon after.

“PLMMS LMT MH GMH” He pleaded loudly, still trying to turn his head. Kali remained seated, and felt her stomach bubbling again. This would be a rough night for both of them.


Pffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff…


Kali’s eyes rolled back again as she pushed another burning-hot SBD hissed out. Dylan began crying as his nose was hit with another of her worst farts.

As it ended, Kali let out a relieved moan. Her stomach was still full of gas, but the long, silent ones were making her belly-ache dwindle. As bad as she was feeling for her younger step-brother, he would have to bear it.

Kali shook her hips, nuzzling his nose against the now-smoldering denim. She had to get rid of this pain in her bowels.


Pffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffrrssppt


“Mmmh~” She moaned again as Dylan continued to fight for his life below. As much as they burned, she enjoyed the feeling after they finished.


Pfffffffffffffffffffffffffffffffffffffffffffffffffrrrrrpt… brrrssssssssssss…


It humored her how many silent killers she had cracked off. And while she once sympathized with Dylan, she couldn’t help but find joy in his body helplessly flailing after every one.


Bbrrrrrrrrrrr… bloooorpt


She leaned back again after pushing two bassier farts out. Her stomach felt clearer for the moment, but she knew there was more in the deeper parts of her bowels. Until then, she would sit on his face.

However, something caught her attention; her jean shorts. They were tight today, and they probably hurt Dylan more than the softer garments she had worn the days prior.

Kali then sat up, allowing her step-brother to catch a breath. She unbuckled her belt in the meantime, and Dylan whined after hearing it.

“My jeans hurt more than my other pants, don’t they?” She asked.

“T-They do..” Dylan answered. “... Y-You don’t have to do that, though..”

“It would be more comfortable for me.” She responded, pulling her shorts down. Dylan turned his head as a pair of plain-black panties were revealed to him.
“It’ll be okay. Now, face forward.”

Dylan knew better than to argue with her; he turned his head back up again & let her sit on his face. The skin-contact made him shudder again, and the smell became stronger as his face was plunged deeper. His regret became stronger.


Sssssssssssssssssssssssssss…


“MMMPH-” Dylan tried to plead again before his stomach flipped, causing him to throw up again. That fart was practically injected into his nose.

Kali leaned against her backrest, sliding her feet to his sides. She sat full-weight again, and practically melted as she lounged on his face.

Even with his struggling, Kali felt at ease in this position. She couldn’t help but smile at the sight of her taller step-brother struggling underneath her.


Pffffffffffffffffffffffffffffffffff…


“Mmh~ there we go.” She hummed after pushing another silent one out, then watched as he attempted to free his legs from the tape-binds.


Pfssssssssss… ssrrpt


Bbrrrrrbrrrrrrrrr…


Prooooooooooooooooooorpt


With nothing better to do, she pulled her phone out & relaxed as she continued farting on Dylan’s face.


Brooooooooooooooooooooort


Prrprrrr… prrrprrprroooooorpt


Pffffffssss…


Brrrrrrrrrrrrrrrrrrrrrrrpt



Kali felt sluggish as she gassed him. It would be evil to take a nap, but considering this would be his last session, he would have to go through Hell before earning it.

Kali closed her eyes as she leaned against the backrest. The sound of Dylan’s panicked mumbling & constant rocking of the bed helped her.


…


…


…


…


…


…


…


“WHAT THE FUCK!”


Kali jolted awake at the sound of screaming. Her vision was foggy, but she noticed a figure standing before her in her room.

“WHAT ARE YOU DOING TO YOUR BROTHER?”

Kali’s heart dropped as she recognized her mother’s voice. And surely enough, as her eyes adjusted, her mother, Reina, was standing with her arms crossed, wearing a brown pencil skirt & pink blouse. Her dark-brown hair was let down to her shoulders.

“... M-Mom?!” Kali panicked as she sat up, practically falling off of her bed. “When did you get back?!”

“Fucking- NEVERMIND THAT!” Reina screamed, then turned to Dylan. He was completely out of it.
“I-... I don’t even know where to start! You DISGUSTING little bitch!”

“Mom!” Kali tried to find a way to explain herself. “D-Dylan wanted me to!”

“It doesn’t fucking matter if he wants you to! You’re his FAMILY!” Reina put a hand over her chest as she approached Dylan. She slapped his face a couple times.
“Dylan? Sweetie? Wake up! We’re home!”

Dylan’s face screwed up at the sound of Reina’s voice. Kali felt relieved that he was awake; now he could explain himself.

Reina turned back to Kali with a deep scorn on her face.

“He wanted you to do this? He’s tied up! He could have fucking died under you!”

“Mmm.. R-Reina?” Dylan mumbled, trying to sit up as his step-mother removed the tape from his wrists. He rubbed his eyes as she moved onto his legs.
“Ugh- god damn… fuck…”

“You need to explain yourself, too.” Reina huffed. “You should thank god that your father decided to go hang out with his friends. Imagine what he would say if he found out you let this happen.”

“Ugh- I didn't..” Dylan responded. Kali’s face screwed up after hearing that.

“You fucking liar..” She huffed. “You wanted me to cure your fart fetish! Tell her, Dylan!”

“W-What?!” Reina’s eyes widened. “What does she mean by that? I thought I told you not to watch porn, young man?”

Dylan didn’t know how to respond; partially because he was still dizzy, but mostly because… how would he? Kali was right.

“Go on!” Explain!”

“... Ugh..” Dylan huffed as he slid off the bed. “I-I used to have a fart-fetish, and I told Kali that I wanted to put a stop to it by exposure-therapy. And she offered to do it for me.”

“You paid me, Dylan!” Kali butted in, and that was news to Reina.

“He can’t fucking pay you. We scan every purchase you two make.”

“Tell him that.” Kali was now fully against Dylan after he tried to throw her under the bus. “He’s been pocketing money from his job.”

“N-No?” Dylan retorted. But Reina turned to him with wide, angry eyes.

“I knew you were putting too little money in your bank! You’ve been lying to me!”


The atmosphere in the room was tense, and Reina rubbed her eyes as she took everything presented in.

“... I don’t know where to even start with you two.” Reina huffed, then turned to Kali. “You’re done. Get some clothes & call someone. I don’t want to see you.”

Kali was taken aback by her own mother outcasting her instead of Dylan. The look in Reina’s eyes evoked stringency; she couldn’t be negotiated with. Kali’s eyes teared up as she grabbed her backpack & filled it with clothes from her closet.

As Kali left her bedroom, Reina turned back to Dylan. “And you, young man. I’m telling your father about what you did.”

“W-Wait-” Dylan tried to reason with her. “O-Okay, look. I fucked up, but I-I’ll do anything if you don’t.”

“Oh- anything?” Reina crossed her arms. “Do you still have a fart fetish?”

“No, I-I don’t..”

“Okay. So what if I want you to smell my farts?” Reina caught him off-guard with that response.
“How about I snap my fingers, and you magically appear behind me to smell whatever gas I have for you. Would you do that?”

“I-I…” Dylan hesitated to answer that. He was completely gut-wrenched at the sound of it. And that alone told Reina how badly he didn’t want it.

“Oh? You don’t want that, do you?” She huffed with a smirk. “Okay! Then that’s your only choice!”

“A-Are you serious?” Dylan felt like crying after hearing that. Reina then grabbed his shoulders before pulling him down to her level.

“Kneel.” She huffed. Dylan grunted as he got on his knees. He looked up at his step-mother; she put her hands on her hips before turning around. Her pencil-skirt hid her ass well, but seeing it so close made him worry.


Bbrrpt!


“SNIFF.” Reina hissed. Dylan’s face screwed up as he took an audible breath. The smell of digested veggies & alcohol filled his nose, and he shook his head with disgust.
“You really want me to tell your father, don’t you?”

“N-No..” Dylan wanted to cry.

“Really? Because you’re struggling a lot down there.” Reina had a smug grin on her face.

Dylan took another audible whiff & shuddered as he realized what he was doing. Reina turned back around & crouched, getting at eye-level with him.

“Oh yeah. This is an amazing punishment.” Reina beamed.
