Bikini/Thong shopping with Sheila pt. III
[Forgot to clarify, Sheila is standing up, but is leaning forward while her back is turned to the mirror, so she's at an angle, which is why the stuff in her crack goes downward, although not in a straight line, it goes diagonally instead]

With whatever strength you could muster, a little surprised there was any left at all, you tried your best at swimming out of the sweat cascade that was dragging you down, but trying to escape from a vertical river was something you could have never possibly prepared for. You sort of jumped and tried to grab onto a drier spot in Sheila's crack, only to keep sliding down since your hands were completely drenched in sweat, and at your size, the watery liquid stuck to you more than you'd have thought. Then it hit you...

"Goddamned physics!" You yelled in frustration as your descent into the seemingly bottomless abyss was inevitable, but even worse it was that various house sized drops rushed past you, each giving you a mini heart attack, only to be caught for a second time into another cascading sweat river. This one took you all the way to the bottom, and violently splashed on a soft, but not Sheila's cheeks kind of soft, surface. It felt somewhat rubbery and plump.

"Huh?" Sheila was surprised to feel she was getting sweaty, but only her butt, and felt a couple drops reach all the way into her crack, and a little bit more that splashed right into her sensitive spot. That made her shudder.

The odd surface you were laying on seemingly got stirred back to life, and it began pulsating, though you weren't sure if it was a reaction to the sweat that splashed down on it, or to the tiny impact your body did when it fell on it. You didn't even know what it was, until your eyes, recently stung by said sweat, somehow managed to adjust for the near pitch black darkness you were in, and made out a large round form, larger than house sized to you, with various large wrinkles you could easily fit in. You felt your stomach sink so hard it felt like it got crumpled like paper one would toss to the trash.
'You've got to be kidding me...' You thought

Sheila moaned quietly when she felt something very small hit her most sensitive spot, and it twitched, as if awakened from a long slumber. As it pulsated, she could feel the tiny object on top of it, giggling like a highschool girl when she realized it was you.
'Oooh, naughty' she quietly chuckled, but this time, she put two and two together, realizing it was her sweat that dragged you all the way there. She eagerly 'clenched' onto you to get a feel of your tiny body.

Sheila's butthole pulsated more and faster, and the parts that did more of that were the ones near you, and the one directly under you, much to your horror. You tried crawling away, but this only stimulated it more, and with its constant clenching and unclenching, it carefully guided you to one of its wrinkles, which then pressed into you, encasing you into the rubbery stuff. This only made it twitch faster, and clench and unclench faster upon your diminutive body, as if it were chewing on you, lightly pinching itself to feel the indentation your body made into it. It made you shudder, but you realized she was loving feeling you there, and there was nothing you could really do to free yourself...

More sweat drops collected on her enormous butt and fell down her deep crack, interrupting the fun she had, as the feeling began to annoy her, even give her a slight itch. Even she didn't like getting a swamp ass, and that's what was happening.
"Oof, such a shame, this bikini looked really good..." She said, knowing wearing this at the beach would likely make her way uncomfortable. She looked at herself in the mirror. Fortunately for her, the sweat rushed down her crack as soon as it collected, and the red cloth itself didn't get any kind of sweat stains. That tempted her, at least for a moment, but it ended when more sweat splashed its way down her cavernous crack.

Since she didn't have anything at hand to dry herself off with, she thought about how to handle this for a moment, but it didn't take her too long, as she soon came up with a solution, one that she had just used, albeit for a different issue. Owing to it being one of her 'gassy days', the pressure in her lower gut was quick to build up, like it had done many times already. If she could blow away an entire pair of itchy panties, she sure as hell could get rid of the sweat pooling up in her crack.

The plump rubbery walls that held you began trembling, as you heard a faint gurgle coming from below.
'Really? What is it that you want?! How much more must I take?! Are you not amused yet?!' You mentally cursed at the Heavens, too weak to do so verbally. Soon, the giant anus puffed out as it was struggling to contain an overwhelming pressure on the other side, this squished you tightly in the wrinkle you were trapped in, but despite its rubbery texture, it was still soft enough to have some "give" and engulf you, rather than crush you.

"I suppose it's not as fun with the unexpected swamp back there" Sheila said, quietly chuckling
"But don't worry hon, Auntie will get rid of that swamp in an instant... By this point, I think you know the drill..." She laughed a little more
"Just hold your breath and hang on tight" She cheerfully instructed, severely underestimating just how terrible her farts actually were, even more so to someone so small.

Your eyes widened again, and you hopelessly tried to wiggle free, but the taut plump flesh that encased you wouldn't yield enough for you to move, and your movements, as small as they were, only made it twitch faster. Sheila moaned softly, wondering for a brief instant if it'd be okay to let out another of her infamously big farts upon her best friend's tiny son, when he was practically at ground zero, but her previous notions that it wasn't all that bad made her shake the thought off. She let this one build up a little bit more, and with little effort it violently exploded out of her crack, a much louder hurricane monster of a fart that even managed to make the cubicle's door rattle. All the sweat that had been pooling down her crack was instantly blown away, hitting the back of the red bikini bottom she wore.

You had already seen worse fart after worse fart, and even knew Sheila could probably outdo the worst one if she so wished, but even with that notion, when the next gigantic explosion ensued, you felt even more helpless, the noise was insane, it was but a massive shockwave that swept across your body, feeling like it could even turn your bones into jelly and make them ripple, together with every single other organ in your body. You let out an intelligible but extremely angry scream as the excessively violent winds tore you off your tight confinement and sent you flying away at breakneck speeds until you harshly slammed into the red fabric wall that was her bikini bottom, but the enormous fart kept on blasting. You had lost near all notion of time, and just waited for the seemingly endless torture to come to an end, which eventually, it did.

Sheila's humongous fart lasted two whole minutes before it finally died down. She imagined that to you, it could've been a more exciting ride than any rollercoaster, and shook her hips to tease you.
"Well, this one looks good, but it makes me sweat too much... though maybe it could work for when I go to a sauna..." she said, getting more thoughtful by the end of her phrase. She then picked you out of the bikini and took it off.

"These weren't quite what I was expecting, but I hope the show made up for it" She playfully winked at you. There were more pieces of clothing she had chosen, but after getting the results she did with just the first 3, she wondered if it was worthwhile going through the rest. On the other hand, despite their cons, she liked these ones she had chosen, and could even wear them in spite of the issue they gave her if she so wished.

[Choice 2]: "You know what, this thong looks and feels lovely. I want to wear it... and I bet you'll love the close-up to my beautiful booty..." Sheila buys all the clothes she chose, but right after paying, she goes to change into her new thong, and puts you inside. The constant tickling, her being already gassy, and maybe the breakfast she had will combine to create the worst storm you'll have handled so far...

---------------------------------------------------------------------------- -------------------------------------------------------------------------------- ---------------

[Choice 3]: "Hmm, these panties look really good, but the itchiness sucks... Maybe we can give it another try, if my trusty little nephew helps me scratch back there where I can't easily reach" She suggestively says to you...

---------------------------------------------------------------------------- -------------------------------------------------------------------------------- ---------------

[Choice 4]: "This bikini looks too good not to get... besides, I already sweated on it... so, I think I wanna gve it a try. How bad can a little bit of sweat be? But just in case, don't drown" She chuckled...
