Applejack looked down at Rainbow Dash with a sly smirk atop the cloud factory service pipe, looking at the stuck spherical form of her rainbow friend while shaking her head. "Look at what y'all got yourself into. How're y'all gonna get outta this one?" Applejack asked with a huff. "It's bad enough eatin' clouds got you to this size, but what in tarnation was you thinkin' chagrin' headfirst into one of these here doo-hickies?" Applejack scolded at Rainbow Dash with a less-than pleased expression as she tapped her hoof onto the piping. Rainbow Dash chuckled nervously, with an even more nervous grin, stuck waist deep in the transparent cylinder of the cloud machine. "Well, you know me; always up for a challenge...heh...I guess I sort of kind of misjudged the opening..." Said the rainbow maned ballooned pony, seeming to sweat profusely while she struggled to dislodge herself from the tube.

Applejack sighed deeply and was about to retort, when the machine whirled to life again, clouds rapidly building up inside and pushed right against Rainbow's face, more specifically her muzzle. Rainbow Dash let out a little yelp as the white fluffy clouds rapidly pushed against her wailing face,forcing her mouth to open wide just as she was about to let out a retorting yell. The rainbow maned mare failed to realize that the clouds were actively pushing into her face at a high volume and as result,it wasn't long before the cheeks on her face were puffed out as the material begun rushing into her mouth, down her throat and inside of her already inflated torso. A garbled retort soon followed suit. "Applejack! Don't just stand the- BLAUGHURGHAUGHCKLCKL." Was all she could muster, as her torso further expanded, plumping up her already inflated up body to twice its size gradually, and climbing. Looking like a big blimp, she actively kicked her back legs in an effort to free herself, to no avail.

The pipe forced her upper torso to remain roughly the same as the air pressure pressed that portion of her upper body against the transparent glass with a firm grip, forcing all the clouds and air to subside in her lower body, to which has forced everything from the waist down to inflate twice as fast as the rest of her body starting with her two large cyan globes that had a rainbow lightning cloud stamp on each one of her flanks, which creaked and swayed with the rapid growth she was gaining.

Then came her lower haunches as her back legs expanded rapidly, slowly inflating as well though not as rapidly. To compensate for the growth, her cutie marks stretched out to large proportions, stretching just a little smaller than her flanks were. Rainbow Dash tried to flail her front hooves in an effort to escape, to no avail. Just as the clouds finally stopped for the time being, the cyan race horse panted and coughed up some clouds and responded "A-Applejack! A little help?!" Barked out Rainbow Dash as she burped out a few more clouds. Applejack smirked and narrowed her eyes a bit. "What's in it fer me?" Said the orange work horse with a sly expression. Rainbow Dash groaned In frustration, and was about to argue her point, before the machine whirled to life again. "Whadeya mean, "What's in it fir me?"?!! I'm stuck just get me ou- AOUGHAUGHOUGHRAUGHLCK." Rainbow Dash managed to garble out, as the clouds rapidly rushed into her, causing her lower body to resume its growth. Those two sky blue cheeks behind her continue to enlarge and engorge, causing her plot to begin rumble slightly, gradually intensifying with the added space rapidly filling her abdomen and fill her body with those lighter than air clouds. The groaning turned into ruffled squeaking of her large flanks that sounded like two big blue balloons squeaking together as they bobbed up and down simutaneously, swaying and gyrating with the wind. After a few moments the cloud making machine eased up and whirled to a stop. Rainbow Dash coughed up a few more clouds as she panted. "Applejack come on! I really need your help!" Rainbow Dash begged, her upper torso was lodged and wasn't going anywhere anytime soon, while her lower torso and everything below,looked like the biggest blue twin blimps that anypony has ever seen before.

Applejack was dumbfounded, showing a flabbergasted expression with her maw gapped open while her eyes gone wide. "Whoa nelly! Rainbow Dash, yer twice the size as before! Well, at least the bottom half o' y'all is." Exclaimed the orange apple pony. Rainbow Dash's eyes widened, as she realized that the sheer amount of clouds inside her body was going to become too much for her eventually, knowing it'll have to go somewhere at some point.

A low gurgle could be heard from inside her abdomen, which made the ballooned mare become a bit anxious. Rainbow Dash struggled to free herself as she knew exactly what that meant, and also knew that, at the risk of humiliating herself severely in front of one of her besties, she had to alleviate her discomfort, and she had to do it quickly before another wave of clouds hit her. "Quickly, pull me out! Pull me out, pull me out, pull me out! Hurry! Please pull me out!" Rainbow Dash pleaded Applejack, whom chuckled and smirked a bit. "What's amatter Rainbow? Ah thought yah liked practical jokes!" Applejack snarkily remarked, laughing loudly.

"Applejack you don't understand, I'm going-" The mare attempted to say, as she felt the machine whirl to life again and swallowed a lump in her throat. "Oh no...too late..." Rainbow Dash whimpered to herself as she had little time to prepare herself for the next wave, which hit her instantly without much warning, and with a vengeance as it was twice as more powerful than any other time, which would mean it was going to last for much longer as well. Rainbow Dash's garbled retorts were muffled by the powerful gusts of clouds that rushed back into her body again, rapidly rounding her flanks and her belly out. At this point the skin on her body begun to become smoother and a bit shiny in contrast to her body.

That grumble in her gut intensified tenfold by quadruple, causing her rump to rumble and creak rapidly, begging and eager for that sweet relief that she desired so. Rainbow Dash knew she couldn't possibly release it all now, especially while Applejack is staring right at her. Rainbow Dash whined and groaned as she clenched her plot cheeks as hard as she could, causing them to squeak and wobble with the pressure that was forced to subside back inside of her, fully expecting the cloud maker to halt for the time being. Only for her the clouds didn't seem to stop at the time she expected them to, and infact rushed into her quicker and harder with larger quantities, causing her insides to gurgle louder as her body begun to tighten up from the pressure that was quickly building. Rainbow Dash whined a bit desperately clenching her flanks harder, forcing the pressure to build up further.

Applejack raised a brow and saw that her friend was struggling with something and frowned a bit to see her in discomfort. "Y'all alright over there, partner?"Applejack called out, concerned. "Hey now...I-I'll help ya out now, alrighty?" Applejack said, seeming genuine at this point. Rainbow Dash struggled to form a proper sentence, though managed to garble out some words. "I...can't..." Rainbow Dash muffled out, as she increasingly grew larger by the minute. Applejack rubbed the bottom of her chin and thought for a moment. "Ya can't what? What can't you do, sugar cube?" Applejack asked, watching Rainbow Dash strain herself, observing her struggling and her motions closely. With each moment her struggle became more frantic and more intense, her body tightens, and her plot cheeks rumbles harder.

Applejack widened her eyes as she begun to piece together what was going to happen. Applejack grunted as she prepared to jump onto her to release her, just as the cloud machine rumbled, kicking it into high gear as it begun pumping out clouds faster and harder briefly while vividly vibrating, throwing off Applejack's balance and almost caused her to fall, forcing her to clutch the vibrating cloud maker. "Hold on there, Rainbow Dash! Ah'll think of somethin'!" Applejack yelled to Rainbow Dash, who expanded tighter and larger, almost causing her to literally cry in vain as the pressure was becoming too much for her to handle. One way or the other, she was going to blow. "I...I can't...Hold...it...in...!" Rainbow Dash yelped out in agony. Applejack instantly jumped into Rainbow, pulling out a lasso from behind her and wrapped it around Rainbow's large belly, which surprisingly effortlessly wrapped around her tightly. Applejack yelped as she begun jumping up and down on her massive buoyant body. "Like hay you can't! You hold them there clouds in! I'll get y'all outta this here mess! Ngh! C'mon... just a little more..." Applejack grunted, as with each jump her giant flanks bobbled up and down, the pressure worsening by the moment. Applejack begun to sweat as Rainbow's flanks engorged larger, almost overlapping her back. The Orange pony bit her lower lip as her pupils dilated upon hearing that noise they both knew all too well; a loud gurgle coming from Rainbow Dash's belly, that traveled downward. "R-Rainbow Dash...F-fer goodness sake, please hold it in!" Applejack said sweating profusely as she jumped on Rainbow harder, forced to jump on her flanks since that was the most available space at the time, a poor place to be right now.

"I'm...tryiiiiing...!" Rainbow Dash yelped out as more clouds continued rushing into her body. "Well try harder!" Applejack responded, losing her balance a bit. With each time Applejack jumped, Dash begun to slide outwards, everso slightly, inch by inch. With one big stomp, Rainbow Dash was quickly pushed outward, forcing her to a downward slope, while still being stuck she was slightly lesser so. This sudden movement downwards threw Applejack off balance and caused her to tumble backwards. The only thing that saved her from falling was the fact that she grabbed Rainbow Dash's tail just in time, forcing her to wedge herself right between those massive mounds that were Dash's flanks, and couldn't move due to how hard she was clenching down.

Applejack begun to frantically attempt to pull herself out, in fear of what will inevitably happen. "Rainbow... A-ahm stuck!" Applejack screamed out in vain. Rainbow Dash couldn't even hear her, let alone see her or even react to any of this. Unable to do much, Applejack held onto her Stetson and gripped Dash's tail tightly and closed her eyes just as tightly, Rainbow Dash felt the pressure grow, tightening her flanks hard enough to make them rapidly rumble and wobble, desperate to release the pressure withinm pressing Applejack firmly between her massive flanks hard enough to cause her yo yelp in agony. Rainbow Dash had no choice, as her flanks loosened up slightly and begun leaking out a quick squeak of clouds, the calm before the storm if you will,wafting right in Applejack's face causing her to gag a bit from the stench. "N-nooooo...Y'all wouldn't dare...Ahm warnin' ya Dash...don't...y'all...da-" Was all Applejack could muster out before...

An atomic explosion of rainbow-colored toxic gas-clouds instantly begun erupting straight from Rainbow Dash's rear with such force that it not only did she push herself further into the cylinder by a few inches at least, but her tail begun to flap rapidly along with Applejack that was attached to the follicles, to which she held on for dear life as it was quite the long drop down. At the same time she was forced to endure the full force of her violent 'Sonic Rainboom', which created a noise that could be heard for miles cutting through the silent air like a hot knife through butter.

BrrrrRRRRRRRRFFFFRRRRRRRRRRRRRRRRRRRRRRRRRRRRRPPPPT!!!!

Rainbow's rear seemed to be endlessly expelling fumes, what would appear to be many days of backed up toxic rainbow clouds that spewed from her butt, a stream of rainbow colors exploded from her rear with such force, it caused her tightened flanks to ripple and wobble while they gradually begun deflating, losing the shine and gaining elasticity. On top of all this, the clouds never stopped pumping into her, only now they seemed to be pumping out four times faster, quickly replacing the clouds that were released via Rainbow's plot, even expanding her rear passed their limits and caused her to fart harder, directly onto Applejack whom was barely holding on, seeming like she was losing her grip while the flatulemce deepened in bass and volume.

BRRRRrrrrrrraaaAAAAPFLLRPT!!!!!!

"Nngh...gotta...hold...on...!!" Applejack panicked as the wafts of rainbow fart clouds blasted in her face, stinging her eyes to the point where she had to close them. Applejack grunted loudly while holding her Stetson between her teeth tightly as she clutched Dash's tail with both hooves tightly with all her might. The feeling of her tail pulled only intensified the wind harder, slightly so. Applejack hardly noticed that her red scrunchy became undone and caused her mane to flow backwards, napping up and blasted backwards with the vigorous amounts of backblast she was currently enduring, by force of course since she didn't have much of a choice in the matters. Applejack was forced to close her mouth let alone her eyes and simply wait out the storm until it stopped exploding in her face.

Rainbow Dash groaned as her gaseous terrors were slowing down, right as her fart clouds begun to slow down, slowly sputtering to a halt, granting Applejack a few moments of a breather...which wasn't much of a breather since the air was so dense with rainbow fart gas that it was hard to even see. "Urck...ack...Rainbow dash ah have neve-" Was all Applejack could muster, before she was forced to endure wave two.

Somehow, this time around, Rainbow Dash managed to grow twice the size and erupt a gaseous bomb that was twice as powerful, twice as long, and twice as smelly, erupting a sound of what about one hundred plus Sonic Rainbooms going off at once,resulting in a cluster of atomic rainbow stink clouds exploding with such velocity it almost blew Applejack right off her tail, her Stetson just barely holding on by a few threads.

BrrrrrrrrrrFLRRRRRaaaaAAAAAAAAAAAAPT!!!!!!

The warm wafts of rainbow fart blasts right onto Applejack felt warm, as one could expect though it wasn't pleasant by any means. The force of the wind would make her ears fold backwards and her fur to frizz up slightly, and the smell was just awful, stinking worse than anything she's ever dealt with back on the farm. Even the pigs didn't smell anywhere near as bad as Rainbow's plot wafts did, in which such events would entail for quite some time. Rainbow Dash could only close her eyes and await for it all to finish for the time being.

After a couple of hours, Rainbow Dash got what she wanted as the machine finally begun to whirl down, sputtering to a hault. The Cyan coated rainbow maned cloud busting pegasus slowly begun deflating enough to where she could plop herself out of the piping, seemingly shrinking to half her size, or to what she was when this whole debacle started which was still pretty big, blimp worthy. The air that was still in her, roughly half the clouds, evenly disperched throughout her entire body with a floomping sound which evened her form out, turning her entire body into a floating blimp albeit half the size she was previously. Since she didn't have to use her wings, she would simply buoy back and forth while fluttering in the air effortlessly. Rainbow Dash turned her head to look back at Applejack, whom was less than pleased.

Applejack slowly climbed onto Rainbow Dash's back and fanned the area. "Heh...atleast I'm out of the tube now, heh..." Rainbow Dash said nervously, to which Applejack glared back at her. "Y'all're lucky ahm yer friend, Rainbow Dash... Oth'rwise ah'd hightail it outta here by now!" Applejack fumed, seeming upset. "I'm sorry, okay? It's not like I meant to do that!" Rainbow Dash fumed back, her face beat red witrh embarassment. Applejack rolled her eyes and tightened the lasso around her and used it as a means to hold onto Rainbow Dash without having to use her hair. Applejack continued, "Y'all're also lucky that nopony else was around to see this here situation or y'all would never hear the end of it..." Applejack said, placing her hat on the top of her head with a huff. "Yeah...that would be pretty embarassing...especially if the Wonderbolts were here. They'd start calling me 'Rainblimp Gas' or something..." Rainbow Dash said with a huff. Thankfully, there was just Applejack and herself there. Silence fell the area, and after a few moments there seem to be nothing else other than Applejack and Rainbow Dash floating there, slowly decending downwards...that is, until a familiar groaning sound could be heard.

Both Applejack and Rainbow Dash's eyes widened as they both knew what this could mean. "Oh no..." Rainbow Dash said, looking at the machine, and the specific pipe she was previously stuck upon and looked at the lable. It said 'Experimental Expanding Clouds, Expand to Four times their mass for easy weather managment!' Rainbow Dash was only expanding due to the sheer volume of clouds rushing into her before...though that was hardly the problem as the clouds that were inside of her would inevitably expand like the lable said. "Those are Self-Expanding clouds...specifically made to grow up to four times their normal size for effortless weather..." Rainbow Dash explained as she sweated nervously, as to what will happen...As soon as she heard Rainbow's stomach gurgle again, Applejack clutched onto the ropes that were secured around her as tightly as she could, quickly strapping herself onto her smooth inflated back to prepare for the events that would transpire.

"Hang on there...L-Let's point ya in a safer direction..." Applejack said, attempting to pull her from the side in an effort to turn her so she wouldn't damage anything, into the open area. "It's gonna be a bumpy ride...!" Soon, Rainbow Dash's buoyant, balloon-like body begun to expand at a rapid rate, expanding moment by moment and begun to inflate much more rapidly to the point where even her forelimbs inflated a bit, as well as her wings and her cheeks. The only think not inflated was her mane, her tail and the general shape of her head.

Rainbow Dash eventually inflated to four, to six times larger than she previously was, measuring well over one-hundred-and-twenty inches in diameter,gritting her teeth and closing her eyes as her flanks rumbled rapidly again, that gurgling in her gut never stopped and only got worse as time went on. Rainbow Dash couldn't even try to hold this one in, seeing as she couldn't hold it in the last time. Her flesh tightened up, and even became slightly transparent...though she wouldn't explode, it definitely would sound like it. "What's the holdup Rainbo-" Applejack tried to say, before something happened.

"Here it comes...!!!!" Rainbow Dash exclaimed, as she loosened her plotcheeks, raised her tail instinctively and slowly let out a few toots teasingly, some weak toots were short bursted, and, without any further notice, Rainbow Dash finally gave in to the mass pressure, as she grunted and pushed out with all her might, unable to hold back.

KRA-KOOOOOOOM!!!!

BRRRRRRAAAAAAAAARRRRRRRRRRRRRRRRRRRRRFFFFFFFFFFFFLLLRRRRRT!!!!!!!!!!

A seemingly never-ending rainbow colored atomic stink cloud explosion erupted and expelled from her hindquarters again,only this time it spewed out of her at such a hard force that it quickly begun propelling her and Applejack forward through the air at such high velocity that she barely kept her shape while the airforce was pushing against her body and propelling her forward by her own rainbow-colored cloud-farting flanks with a loud enough noise it shook the ground below Ponyville, causing everyone who stood on land to believe they were having a minor earthquake. Rainbow Dash only closed her eyes as she blasted through a cloud house, destroying it.

Applejack was luckily strapped in tightly, though her Stetson wouldn've flown away has that not been secured as well, clutching Rainbow Dash for dear life feeling her body deflate gradually. "Auuuugh! Sl-slow down, Rainbow Dash! We're goin' too fast!" Applejack protested, to no avail.

"I can't stooooooop!!!!" Rainbow Dash yelled out in vain as she begun to let out a louder, and harder fart to propell her faster, going fast enough to break the sound barrier and creating an explosion of rainbow throughout the lands to see, and smell. At this point there was a streak of multicolored rainbow spectrum stretching the entire lands of Ponyville, Cloudsdale and beyond.

After some time, Rainbow Dash's body begun to deflate gradually, the Sonic Rainboom Fart had slowly nerfed down significantly, and thanks to Applejack steering them away from onstacles Rainbow Dash remained in one piece, for the most part as her plot was super sore from all the blasting she was doing. At this point if she wanted to she could clench down and hold it in again, but since the clouds would just expand again she figured she may as well release it all. However it suddenly stopped as she neared the ground slowly decending thanks to Applejack helping in weighing her down. "Guah...I-I'm slowing down..."

"Finally..." Applejack said, seeming exghausted as they neared the ground, near an open meadow and some ways from Ponyville and all the inhabitants. Applejack tied a rope around Rainbow Dash's tail and, once she was close to the ground, hopped off of her and onto the ground, dusting herself off. "Wheeeeewie. Well Ah'll be Rainbow Dash...Ah never knew ya had it in yah." Applejack sighed out, fanning her hat in front of her face to waft away the smell.

Rainbow Dash blushed in embarassment, "Yeah...who knew right? Heh...heh..." Rainbow Dash said as she sweated a bit more, a gurgling sound occurring in her stomach. "Uuuhm, Applejack?" Rainbow Dash said, biting her lower lip. "Yeah?" Applejack said, turning to see her flanks start rumbling again, followed by a gurgle coming from her belly again. Applejack knew exactly what this meant, and she wasn't having any of it this time. "...Oooooh no you don't!" Applejack said, lassoing her to a sturdy boulder that she believed wouldn't move, a large rock bigger than a building.

Rainbow Dash and Applejack were both thrown off guard as, just in time, Applejack secured Rainbow Dash down, but failed to realize that she still had her hoof tied to Rainbow Dash's tail via the lasso from earlier. "W-wait! Rainbow Da-" Was all she could muster before it happened again.

Rainbow Dash had, at this time, erupted another rainbow-colored fart-cloud blast right in her face, blowing away her Stetson and flowing back her mane like before, except they were on ground. Applejack tried to stand her ground, however that was near impossible as she was quickly flown backwards and, thanks to the rope, she was held from going too far...unluckily is that she was forced to take the entire blast directly into her face, the smelly gasses stinking up the meadow with a thick toxic fume.

Rainbow Dash wasn't going to have this all night so, with a grunt, the cyan mare would force all the clouds in her body down into her plot, and with all her might, another atomic explosive stream spewed out of her rump and right onto poor Applejack's face, now stinging her body with all the force she was forced to endure. This would only last for an additional hour and a half.

After another half hour, which would make this two hours of pure farting boom, Rainbow Dash's body slowly sputtered to a hault after she had deflated down to normal size, and collapsing on the ground of the meadow. Applejack fell back down to earth with a thud and grunted in pain. It hurt, but not seriously bad.

Applejack slowly got up and approached Rainbow Dash, shaking her head a bit. "Augh...hopefully y'all're all finished now that y'all have polluted the air with yer stink-rainboom?" Applejack said, raising an eyebrow. Rainbow Dash could only nod, before passing out and tooting out a small cloud, just for good measures.

Brrt, brrt.

Applejack sighed and laid down with Rainbow Dash, undoing the rope around her own hoof and tossed it to the side. "Hopefully all this here mess will clear up by the time y'all wake up." Applejack said, looking up at the sky to see the air was thick with Rainbow Dash's rainbow fume clouds. Since they both were pretty smelly and they both got used to the stench, it was pretty easy to become nose-blind to it...as for everypony else, that's up for debate. For now, rest is needed.
