It's a great omen when the setting starts out during a thunderstorm in Ponyville right? Well this happens to take place during that time. There weren't many ponies walking around the town. Most of the unicorns levitated umbrellas, most of the Pegasi were keeping the weather the way it was scheduled to be, and most of the earth ponies just ran around in the rain trying to find shelter. One of these ponies, a unicorn by the name of Marisa Ponygal sighed underneath her light blue polka dotted umbrella. She was pretty bored and the weather ruined her chances to play with her friends today. It practically bummed her out.
"Aww dang it," she complained to nobody in particular, "There's nothing to do....oh well I might as well head home." As she was thinking of that, her stomach gurgled and physically rippled her belly. "Oh man...I shouldn't have put so much hot sauce in that.." She grunted, trying to clench her plotcheeks and hurry home. She started trotting pretty quickly, eyes shut trying to concentrate on not messing hersel-
Marisa pumped horn first into the side of a camouflage-green color Pegasus, with a distended belly and a pink now that lay atop her hair. Once Marisa figured out where her horn was she immediately removed it; the agitation of the unicorn's belly caused it to gurgle and then...
A soft gust of wind blew from her sphincter that quickly turned into a wet bubbly zipper that lasted at least 10 seconds. After it was done, the Pegasus started to regain consciousness and tried standing up. Marisa's eyes were widened; not just because of literally running into that pony but with how that fart sounded and - much sooner than she expected - stunk! It literally stunk of manure crossed with a powerful sulphur stench. Marisa covered her muzzle with her front hooves to pretend she disliked the stench, however she did ask the Pegasus, "Hey. Are you all right there?"
The green Pegasus regained her balance and sniffed the air, laughing a bit. "Haha. Guess I didn't hold it in as long as I wanted to." She soon turned to the voice she heard asking if she was alright. She was greeted with a sorrowful Marisa face. "Oh hey. I'm fine. Did you bump into me?"
"Yes I did! I'm so sorry..." She then thought a bit, "Although I think your cutie mark is strange...it looks like a-"
"Fart cloud?" The Pegasus finished without skipping a beat, "Uh yeah. Because it's something I love and am great at it." The pony giggled during that statement. "By the way I'm Samantha!" She put on a smile and extended her hoof out to Marisa. "Heh..I'm Marisa." She also extended her hoof out for a hoof bump between them. "And really...? Farting is your talent? Heh...I knew people were good at it but I never thought it could be a special talent."
"Hehe. Well yeah. I'm obviously really good at it."
"...I mean if that were true then I should have gotten a mark like that. But all I got is this..." She hung her head low and turned to her right flank to see her cutie mark- wait a minute. An idea formed in Marisa's mind. One that she thought would be interesting.
"Hey Sammy- wait may I call you Sammy?"
"Okay then. Sammy, would you like to put your talent to the test?l
Samantha's eyes widened and she brightened at the proposition she was given. Then a slight grin was placed on her face.
"Hehehe. Okay cutie. But I'm gonna warn you that I'm not gonna be beaten that easily."
Marisa raised her eyebrow. "Oh really now?"
"Oh really now."
"Hah! I take it you don't know me like my friends do."
"Okay then Marisa...don't say I didn't warn ya."
Marisa's eyebrows still expressed her pride and arrogance to the matter as she backed up, plot first, onto Samantha's face.
Samantha blushed really hard and tried to conceal her arousal by pretending she didn't like it, all the while struggling with the most minimal effort.
"Hey. Get off of me," she "whined", "this isn't how you treat a princess."
Marisa's rebuttal was quite brief, in fact so much so that it ended up only being one syllable.
With what the girls were doing quickly gathered attention and soon everybody was-
"Hold on!" said Marisa facing away, "Why didn't you use everypony?"
......wait what? Umm...
So what the girls were doing soon gathered attentio-
"Hey answer my question ya dingus!"
Huh...? It....seems that Marisa was conversing with the narrator.
"Stop with that third person bullcrap and answer my question."
Heh heh...it seems the narrator might be hearing things so let's continue the story."
So the girls gathered every-
"Answer me!!" Marisa shouted with puffed cheeks. "Why the hell are you-"
ALRIGHT FINE!!! DO YOU WAAANT TO HEAR WHY I DON'T USE THAT STUPID TERM?!!! BECAUSE IT'S STUPID ALRIGHT! IT'S DUMB! I DON'T CARE IF IT'S PART OF THE SHOW, LET IT BE!! I JUST AIN'T GONNA USE IIIIIIIIIIIT!!!..........*sighs* ya good now?
Great! Now you stop being scared and get back to the story.
So with what the two girls were doing quickly gathered attention and soon everyBODY!...was also quickly gathering around the two. Most of the ponies had grotesque looks, disgusted expressions, even some felt sick to their stomach. However others seem to cheer on Marisa or Samantha or...galloping over to a corner somewhere. Either way, both ponies soon had a crowd around them and Marisa wasn't planning to disappoint. She slid her plot further up Samantha's muzzle and almost as if on cue, her lower stomach is punched with a cramp, to which the pony leans over, and Samantha's body pushes harder on Marisa's already agitated stomach. Without much more effort, the trap was sprung. Marisa was able to produce a massive fart with about half a minute in length, which was pretty long for a pony of her stature. The sound was covered by a loud bassy tuba-like beginning that slowly became wetter and more bubbly before the end of its duration. The massive fart took everybody by surprise; all the other townsponies and, heck, even Samantha was pretty much stunned by the display from her point of view. She blushed softly...and smelled Marisa's horrible stench even more softly. It was a smell she's never come across that often, let alone by another pony. Samantha felt a bit of a high taking in Marisa's stench. And she wanted more.
"Hah!" Marisa started to gloat from above the pegasus, "Stinks doesn't it? Well you get the liberty of smelling that all up!"
Samantha didn't hear her that well, nor did she care. She wanted more of her aroma. Her hooves started to come up and "grope" Marisa's plot, causing the pony to blush. She didn't know how to react. Was she begging for more, or was the stench so bad that she was trying to push Marisa off of her? No matter what the actual answer was, she actually put more weight down on her rear. She didn't want to gratify the pegasus so she inhaled and grunted softly. What followed was a wet and bubbly sound that quadrupled the length and potency of the previous fart blast. Some of the townsponies dispersed and tried to run away from the scene because of the sheer volume of horrible stench. Some others, however, tried to brave the awful smell to continue watching the two ponies to see what might happen next. Marisa looked victorious sitting on top of Samantha.....or so she thought. From out of nowhere, Marisa felt a large push on her flank and her....sphincter? The end result consisted of an upside down Marisa nose in the ground. Marisa shook it off and turned her head around to see where Samantha had gone. To her surprise she had taken flight and was headed right for her. Marisa didn't have enough time to move until-
The pegasus' hooves crashed around the unicorn's body, however her face was a different story. It held no obvious malice or evil, but...creepily eerie happiness. Her smile was plastered on her face wider than any smile she'd ever seen. Marisa was so shocked she couldn't think properly like the idea of teleporting away. Samantha just looked down at Marisa, but then she slowly turned her body around, raised her plot and smashed it down on Marisa's face. The devious unicorn flashed her mischievous grin for which only a glimpse could be seen by Samantha. Then for a split second there was silence until Marisa shut her eyes and grunted. Hard.
What followed was a catastrophically loud blast of gas that not only trumped Samantha's pervious sound blast, but it's stench as well. A horribly potent smog flowed throughout all of Ponyville, immediately attacking the noses of all the denizens. Samantha's nose immediately was hit from the point blank range and it burned through so badly it felt that her muzzle has already burned out and it was burning deeper into her face. Marisa, all the while, laughed nearly manually. Her own smell made her loopy with the lack of clean oxygen around and having her muzzle sealed with the crack of the pegasus on top. So much was going through Marisa's mind but none of it was able to be expressed through any form of language.
'Holy Celestia,' Marisa thought to herself, 'This can not possibly get any worse...'
Marisa's eyes widened in shock when she heard that sharply loud gurgle, then subsequently whimpered when she heard Samantha almost keel over with her front hooves wrapped around her stomach.
"Ooh...h-heh...you're gonna get it now," Samantha said, "I can't wait to gas you down."
Marisa gave up after hearing some subtle intestinal noises.
"...Please don't have it be poop in there."
