Boom. Don't ask why I'm uploading this at 1 in the morning. Just know that this is another lengthy one (my longest story yet, if I'm not mistaken), and another story off of my archive. I do hope you enjoy this one.

Obligatory Gas Warning, in case the title didn't tip you off.

Constructive criticism is welcomed, that's how I improve after all.



In the dead of the night, a large shadow suddenly appeared on top of a single, lonely home on the outskirts of the big city. The figure wasted no time in expertly scaling down the side of the building, and down to the side of a window. Without making a sound, it opened the window, allowing the figure entry into the home. Slowly, this shadow crept inside, examining the area, and assessing the situation.

Her target's home seemed rather basic; there was only enough stuff to suit one person comfortably. Simple enough for any expert to find the target, at least. As she examined the house, she found nothing interesting; to her, anyway. This house really was bare and bland.

The only thing that was on was the TV in the living room, currently continuing a news story about some millionaire that was hospitalized yesterday. The authorities weren’t sure what caused his condition. A heavy concentration of sulphur and methane was found in his lungs, but there was nothing they could find that would reasonably hold so much toxic gas, and no gas tank to be found. The figure smiled to herself. She’d call these cops idiots, but she had to remind herself that she was capable of something many would consider impossible. She didn’t waste too much time watching her own work, and instead kept looking.

It didn’t take long for her to find exactly what she was looking for: Her target's bedroom door. Inside, she heard someone talking. Probably on their computer, she'd imagine.

This would make for an excellent distraction, so the mysterious intruder went ahead and snuck into the room, silently pushing the door open before closing it back again. She was confident now, confident that her target was completely oblivious to his situation.

"Noo, come on, how did you miss?!"

Scott shouted out angrily, moving his mouse about in a fit of anger before going back to his normal state and focusing back on the game he was playing. Unaware of the looming threat just inches away from him, he continued to play and throw tiny tantrums of anger.

The home invader rolled her eyes at how easy this was. This almost seemed like some kind of prank this guy’s friends pulled. However, now that the thought was in mind, it did seem strange that this was the target. The answers will come in time, but the target still needed to be subdued. So, that’s exactly what happened. Without a sound, something large crashed down on the target’s face, engulfing his head entirely. The assailant held onto the chair he was sitting in, fully intending to keep him there until he passed out.

A few muffled, helpless screams came from the panicking Lucario as he was smothered in an unknown object, his headset flying off of his set and landing on the ground with an uneasy thud. His friends on the other end grew worried.

"Scott? Hey, are you alright?"

There was no reply; just muffled screams and useless thrashing until the Lucario felt a lack of air catch up to him, his body going limp and his screams lasting no more. Now that the assailant had full leverage on what she could do, many ideas popped up in her head.

The first thing to do was to shut off the computer, as there was no need to have witnesses. That was done pretty quickly, and it was on to what to do with her target. After getting off of him and letting him breathe again, she was quick to tie up the Lucario, so that he couldn’t run when he woke up. The mystery assailant picked up the Lucario, and swung him onto her shoulder. Walking around the home, the figure eventually found his bedroom, and decided to stage the interrogation there. So, the Lucario was placed on one end of the bed, and the assailant sat there on the other side, waiting for him to wake up.

After around 20 minutes or so, the Lucario's eyes weakly opened and immediately saw a Tsareena, almost certainly the one who had brought him into the situation he was in now. He tried to panically get up and run away, but his limbs were bound to the bed frame.

"Who are you and what do you want?!" Scott shouted, defeated and fearful.

The Tsareena sitting on his bed was massive. Significantly taller than him, and just larger in general. Possibly the largest part of her was the two beach balls of an ass on her. They were nearly twice the width of her own torso, yet held a perfect shape. There’s no telling how much muscle is back there to keep such an ass in shape. Although her species was obvious, even in the dim light of the bedroom, the Tsareena concealed her face with a mask, showing only an eye. However, she almost looked like she was smiling behind that mask.

“My name is not of your concern, and what I want is for you to answer some questions. We can keep this simple, or I can force you to come clean, how we go about this is up to you.”

"Nngh... Y-you've... got the wrong guy, I promise!"

Scott shouted at her, squirming profusely in his tight restraints to no avail.

"I-I'm not the one you want for answers, I'm... T-the one you want for, uh... t-training!"

The Tsareena’s silent, imposing stare was getting to him now, as he slowly bled information to her about his motives.

"I-I heard about what you did to that high-profile person yesterday and it intrigued me a great bit, s-so I wanted to know if I could be of any use to you because you seem really capable, and I want to help..."

Scott continued on and on, eventually wearing himself out and looking down at the bed's surface, defeated.

"I-I..."

The Tsareena said nothing at first, simply staring down the small Lucario. After a few agonizing moments, a smirk crept onto her face from behind the mask.

“There we go, wasn’t that simple? Now, your offer does interest me, but I don’t think you’re quite cut out for assisting me.”

The Tsareena put on the act that she knew about Scott’s true intentions the whole time, but she was rather surprised. She figured you just wanted to have some fun with her, but this was something no one has ever dared to even think about doing. She was easily capable to killing a man, though many contracts she takes wants her targets alive.

“That guy I interrogated last night? He was heavily trained in resisting torture, but my kind of torture is something no one can prepare themselves for. “

"Y-your kind of torture? You surely can't mean, uh..."

Scott whimpered softly as he remembered the consequences of the high-profile's interrogation.

"N-no matter, I'd still like to help you become the very best at what you do; even if your methods are unorthodox..."

Scott spoke, continuing to look at the Tsareena with a curious eye.

“If you really want to help me out, I suppose I have some use for you, but you’re going through with it if you accept, no matter what. That also means you can not tell anyone about me, or about what you will experience, ever.”

The inflection of her voice was more than enough to tell Scott that she was dead serious

"U-um... Well, I..."

Scott gave the proposition some thought for a moment, constantly looking back at the large Tsareena and the bed's surface before ultimately deciding.

"Right, sure, I promise not to tell anyone, no matter how farfetched and interesting it may be..."

“Good, and you will hold up to this agreement. Now, before we can get started, I need to test your resilience. That, and I didn’t make the necessary preparations for your tasks. So tell me, what do you think of this?”

The Tsareena got up for a moment, only to turn herself around, swinging her massive rear around to face Scott before sitting down once again. Right before him was her gargantuan ass in its entirety, while she looked behind her, reading his face

Scott's face immediately turned an even harder red as the Tsareena's fat ass revealed itself to him, his eyes not daring to look away from its perfection for even a moment.

"U-um, it's... quite nice... But... Why are you showing me your backside? Is this part of the test, or something? If so, I'm not sure I'll be able to satisfy whatever you want me to go through..."

“Just wait for it.”

For just a few moments, the Tsareena sat there in total silence, before a muffled, but powerful rumbling sound came from her behind. She sighed to herself as the rumbling went on for 10 whole seconds, before abruptly cutting off. Not long after that, a horrific odor wafted up to Scott’s nose, reeking of a combination of rotten eggs and meat

“There we go...”

Upon hearing the initial start of the Tsareena's eruption, Scott raised a look of confusion in his place before he realized what was happening around 3 seconds in, the putrid stench of her rancid gas smothering his sense of smell with little to no effort.

"M-mmh... J-jeez, that was bad... What do you... eat?” Scott asked, secretly sniffing more of the horrifyingly stinky gas that the thick Tsareena had ripped out of her ass.

“You’re taking this fairly well, better than others. Maybe this will actually work.”

She grabbed her butt, before letting out a short, but raunchy blast of gas.

“I eat a variety of things to amp up the power of my gas, and I’ve been trying out different combinations of foods to see what gives me the worst gas. As I’m sure you can smell, I tried a lot of eggs, with just a bit of meat. What do you think so far?”

"It smells, uh... Quite, erm... n-nice, actually..."

Scott went on, not noticing that his nether regions were growing rather stiff from the rotten smells of her potent ass gas.

"I honestly wouldn't mind if you came a bit closer and gave it to me at point blank... Maybe you can show me how you treat people who refuse to talk at all?" Scott asked, trying to convince her to just straight up fart on his face, since that's what he had wanted the most: Her awful gas.

She raised a metaphorical eyebrow.

“Interesting. So you’re one of those types of people. Well, this should be significantly easier then. So, I’m going to do exactly what you just said, and bring you point blank.”

She lifted her ass up, before moving backwards towards the Lucario’s face. It didn’t take much for Scott to notice that her ass stunk being near it, and the smell only got worse as she moved closer. Scott could only watch her ass jiggle and shake as she moved, before it took up his entire vision. Now the smell of her ass was potent, and Scott could feel the thick musk working its way into his nose and lungs

As her fat, musky ass engulfed the Lucario's head, Scott immediately began to grind his nose against that Tsareena's gassy asshole, the thick, strong female aroma wafting into his nose in large amounts, causing him to moan and pant softly upon taking in such brutal scents at such a high rate.

She pressed her ass against Scott’s head, causing the bed frame behind him to creak and groan. It wasn’t long before she let loose a powerful fart, shaking Scott’s head from between her cheeks. The horrifying odor from before was multiple times stronger now, and was quick to penetrate Scott’s nose

“I’ve been bloated for a good portion of the day, so you might be huffing that for a while.”

The Tsareena's most recent wind-breaking fart left Scott with the wind knocked out of him, his breath raggedly taking in the brutal burst of gas through his nose.

"Mmph... G-got it, er... Um..."

Scott remained silent for a moment, a mixture of thinking and the pure inability to speak after being left stunned from such a horrid blast of gas. Eventually, he'd speak up despite the disgusting stink forcing him to gag slightly.

"What do I call you, you, uh... gassy assassin?"

“Well, that’s not exactly the best nickname, but if you must to call me by something, it’ll do fine.”

The Tsareena started rubbing her massive ass across Scott’s face multiple times, smearing her stink into his fur. Then, as if to mark her stench on him, a deadly SBD leaked from her ass, slowly spreading out and into Scott’s face. The smell was beyond human possibility, reaching some unholy level of pungent, noxious, and acrid. A smell fit for a goddess.

“Sorry about that one, I needed to let that out. Tap on my butt if you stay conscious afterwards”

As the airy SBD blew into Scott's nose, he gagged and felt his ears tear up immensely, the feeling of death itself stroking him on the back, saying, ‘Hey, if you die right now, it'll be better than this!’ However, Scott fought back the urge to think that way and instead pleasure his new "boss" by weakly tapping on the mountainous ass in front of him with slight hesitation.

Feeling the tapping, although weak, she let out what sounded like a sigh of relief

“Oh good, I’ve accidentally killed people like that more often than I can count. I think you earned a breather after that.”

She took her ass away from his face, sitting down on the bed again as she let Scott recover from his recent gaseous assault

The moment she let Scott breathe in relatively fresh air, he gasped sharply and continued to do this for a few moments before going back to silently sniffing the tainted bedroom air. After getting a noseful of the spoiled air, he jittered softly.

“You smell r-really good, my gassy assassin... Those eggs are really working!"

“They certainly are, but I think this is on the weaker end of what I can do. It certainly smells weaker to me”

She suddenly blasts some of her eggy gas onto Scott’s bed, and with how potent her fumes are, there’s no telling if the smell will ever wash out

"Oh? Well, if that's the case... Maybe you can go to my kitchen and eat whatever you'd like? To... give you gas?" he'd ask before being interrupted by the grass type's loud and bassy gas, the eggy fart causing him to become briefly light-headed. "A-and, if you don't mind... may you unbind me? You don't have to, but I'd like it a lot..."

“I might take you up on that offer, so let me get you out of that.”

She leaned over, undoing the ropes enough that he could easily wiggle them off. Then, she slid off of the bed, making her way out of the room, and undoubtedly towards Scott’s kitchen. She was so tall that she had to duck under the door frame to get through. Scott could see that she swayed her hips when she walked, causing her ass to constantly jiggle

After being unbound from his tight restraints, Scott hopped out of his bed and followed behind the thick Tsareena, his eyes carefully evaluating just how jiggly those two orbs of grass type ass were. And, surely enough, he quickly came to the conclusion that those two cheeks were the most jiggly he had ever seen.

As she walked through Scott’s house, barely fitting under the roof, Scott noticed that she barely made any sound when she walked, even with her size, and on his hard wood flooring. No wonder she’s so good at sneaking around, even with her height!

The Tsareena made it to Scott’s fridge in no time, lightly pulling it open, before bending over to see its contents.

Scott, being the excited jackal that he was, uninvitingly rubbed his hands along the Tsareena's thick, bubbly rump.

"Mmh... How'd you get this thing to be so big...? It's like two planets are strapped to your back..."

Scott leaned in and gave both cheeks a soft, loving kiss.

She certainly wasn’t expecting to feel Scott touch her ass, but she did an excellent job of suppressing her surprise

“A combination of rigorous exercise and just the right diet.”

After some searching, she stood back up, carrying a couple boxes of leftovers Scott left in the fridge, and setting them down

“These will do.”

Scott was left dumbfounded by the amount of food she brought to the dining table. ‘Must need to eat a lot to keep up her body,’ he'd think. As she sat down in the chair that didn't even come close to holding up all of her weight, he heard some ungodly groans and creaks from the chair, its very life being drained from it at the moment.

"So... You're gonna eat all of that and then try it out on me? It might take a bit to digest..."

“That is true, so I’ll simple wait for the food to digest. In the meantime, I require more of your services.”

She opened up a box, and started eating everything out of it, regardless of what it was. As she sat, the chair beneath never stopped creaking and groaning under her weight; it was a miracle it isn’t broken yet.

"Oh, of course! What can I do for you, er... I still don't know what to call you, but... How can I help?"

Scott stood up attentively, ready for whatever she was going to throw at him. As he heard the god-awful sounds of the chair's desperate moaning and screaming, his face cringed up slightly.

“This chair is hard; I require something to make it more comfortable. I don’t care how you do it, but I demand it.”

She continues to gorge herself on old leftovers, easily finishing an entire box in little time.

"O-oh! You need a... ah, jeez—what is that thing called? Ah, no matter; let me go get it..."

The Lucario quickly scurried off to his room and grab one of those pillows you place on a chair for comfort reasons and return to the dining room before presenting it to her.

"Here! You place it under your butt and it makes the seat soft."

The Tsareena merely glanced over at Scott.

“Alright, let’s see here.”

She momentarily stood up, placing the cushion onto the chair, before sitting back down. However, the cushion was squashed flat by her weight, disappearing entirely from Scott’s view. It was like the cushion was never there, and she certainly felt that way

“Not enough, I can barely feel it.”

"H-huh? Well, I..."

Scott tried to think up something to say, but only came up with one small thing that would possibly anger her. But, being the nitwit that he was, he decided to say it anyways.

"C-certainly your large backside acts as more than a cushion for you, no? It looks and feels soft, so why would you need something to put under it?"

While she wasn’t angry, she definitely sounded annoyed.

“Just because I have a large ass, doesn’t mean I can’t feel the cold wood on my ass. Now, hurry and find something to use as a cushion, or I’ll use your face.”

"I-I... I don't think I have anything else besides those cushions... Maybe you could sit on my couch and eat at the coffee table? It's quite nice; it even reclines! H-heh..." he'd say, trying to "advertise" and persuade the threatening Tsareena into not making him her seat.

“...Sure, that will work.”

The Tsareena went ahead and picked up the remaining boxes of leftovers, and stood up. The chair beneath her was malformed now, the wood bent to an irreversible state. She ignored this and walked over to Scott’s couch. Then, she unceremoniously sat down on the couch. She sunk into the couch, squashing the cushion flat, but she was comfortable this time

“This is acceptable.”

Having seen his semi-new couch get practically ruined within moments basically crushed Scott's heart, but he knew he couldn't complain so he sucked it up and sat down in what little space the couch had left.

"Um... So, I noticed you eat quite fast! You've had a lot of experience, huh?"

Scott awkwardly laughed to himself before looking away from embarrassment.

“It’s important for me to be able to fuel myself on short notice. There have been too many instances where I had a job in two or less hours.”

As she worked on the second box of leftovers, she leaned to the side slightly, and blasted a deep, sputtering fart, the couch taking the brunt of the smell.

"Mmh... R-right. How come your gas is so... e-ech... nuclear? It smells like death and it only gets worse as time goes on..."

The Lucario turned red as she ripped another one of her signature weapons out. And, of course, Scott would still be as choked up as ever on that smell. That awful, potent, will-breaking smell... At any point, Scott could have said that he was starting to become addicted to it.

“Well, I had some help from genetics, as I was terribly gassy from when I was young. However, I did spend several years training up the smell, and further increasing my gas output. It was all necessary for me to be able to break the minds of men with my gas today.”

It was terrifying how nonchalantly she spoke about this, about breaking people from her gas alone.

And, as a consequence from hearing how naturally she spoke about such an odd topic, Scott broke a nervous sweat and began to look around the room in a slight state of panic.

"B-break minds, you say? Um... How many people like me have you broken? S-surely none, right? H-heh..."

Scott was visibly nervous now, begging to Arceus that she wasn't planning on breaking his own mind.

“Well, there have only been a couple cases where I gassed individuals like you. The rest of them did not take my gas as well as you are now, so consider yourself better than them.”

The Tsareena has downed the second box of leftovers, and put the box aside before laying back on the couch, allowing her gut to digest her food. Speaking of her gut, it was rumbling frequently, hard at work digesting her food at an unbelievable rate.

Scott wasn’t exactly relieved to hear that, his nervous sweating continued, now looking around the room as he spoke.

“T-That’s good to hear! I guess that means I’m doing good as your training partner, r-right?”

The Tsareena didn’t say a word at first, and instead leaned forwards slightly. Her ass soon erupted with a bubbly fart, a large portion of the gas forced into the couch cushion. Some gas did escape, but what did escape made Scott gag silently. Her gas was somehow getting so much worse as they spoke!

“I think you’re doing fine, for now. However, you better be a quick learner, because I think my gas is going to outclass you soon enough.”

The Tsareena suddenly stood up, moving over so that she was standing in front of Scott, her monumental rear right in his face. She leaned over ever so much, enough to where her cheeks parted, and Scott could catch a glimpse of her asshole. However, Scott was quickly hit with a wall of powerful fumes, courtesy of the gassy assassin. He was forced back into the couch, his nose left vulnerable and exposed to the full force of the Tsareena’s weapon. He could clearly smell the leftovers she ate just minutes ago, except they were much more rotten on the way out. Was this her true power? Or was this, too, just a fraction of what she was capable of?

Scott wouldn’t have much more time to think about it, as the Tsareena’s bombastic minute-long blast slowly transformed into a pungent SBD. Her gas was transforming into something that you couldn’t simply call gas. Scott would better describe it was a kiss of death. The soft breeze that brushed past his face and body, carrying a smell so noxious, so atrocious, the Lucario was out in seconds. The smell was still burning in his snout, leaving its scar on his memory. This was the smell of a goddess, the smell of his new goddess.

The Tsareena didn’t even turn to see if Scott passed out, she knew the answer already. She stood back up, giving her ass a small rub as if to reward it for her latest fart. Her job was done, for now. She knew she had the jackal under her control. However, she truly did see potential in him, potential to survive her deadly fumes, designed to incapacitate and kill. If she worked with him enough, she could have a personal fart cushion for the rest of her days. Not only that, but he’d be perfect for testing new diets and their effects on her stomach.

For now, the Tsareena’s work was done. As she sauntered to the front door, the rest of the world continued as normal, clueless to the events of the single lonely house on the outskirts of the big city, and the changed life that resided inside.
