"Wait, what?!" You said, quickly realizing that you were on the chair again and having just heard what Lillian said.

"Aren't you curious? I wonder what's the limit for your shrinking" Lillian said.

"But we don't even know if this is reversible!" You protested.

"Blaise, please... if you're shrinking from a freaking smell I don't think it'll be permanent, it'll wear off eventually... I think"

"This is a bad ide-AH!" Lillian once again swiped you off the chair with blinding speed and she held you before her face just like before.

"After seeing Jen having her fun with you I've gotten some ideas for my own kind of fun" She said, making you even more nervous than when Jen teased you. Lillian smiled at your reaction, which she took as you being flustered.
"I might not have her impressive knockers, but I've got something a lot bigger and better" She said with a suggestive wink, and a loud slapping noise confirmed your suspicion as she had spanked herself.

"I'll agree to the bigger part, but I'm not so sure about it being better" Jen said, throwing a small jab at her larger friend.

"Of course it's better, he likes butts better than boobs" Lillian said and swiftly brought you around her waist, using her free hand to pull back her very puny and ill-fitting yellow thong, dropping you down into an even deeper, darker and for sure smellier abyss.

"Well, your ass ate him too just like my boobs" Jen said. The sheer size of Lillian's ass still impressed her to this day in some regards.

"Oh, but it hasn't swallowed him for real yet" Lillian replied, blushing a little at her own joke. Jen took a few seconds to process it before it clicked in her head, and when it did she broke out into a giggling fit while covering her mouth and trying to hide some of her own blush, which had quickly come back after it had taken a while to fade.

This was similar, yet drastically different to your time in Jen's cleavage. For starters, the gigantic walls that enveloped you were much squishier and gelatinous as well as warmer, and the weight that bore down on you from both sides was much greater. Thankfully, with how incredibly plush and soft everything surrounding you was, you couldn't get flattened even under this overwhelming pressure. But while you were embarrassed and then relaxed in Jen's cleavage, the only things you felt from being stuffed down Lillian's titanic buttcrack were dread and disgust, as you could smell already a hint of her previous farts.

Like the previous times, there was little warning and soon you were bombarded by a tremendous hurricane while a thunderous, bassy boom made your doughy surroundings wobble and ripple to its furious tune, also making them bounce into each other, adding more booming noises to the overall cacophony that blasted past you while everything shook as if in the middle of a catastrophic earthquake.

Soon, you felt that dreadful, uncomfortable dizziness as your body contracted into itself, losing some more of your height as everything around you intensified, the weight pinning you in place became heavier and your surroundings felt even softer and squishier, which you didn't even think was possible.

"Did it work?" Jen asked with a bit of guilty curiosity after hearing Lillian letting out that sudden, big fart.

"Yep. He got smaller, but only a little... then again, I still have a lot more in reserve" The chubby Brazilian laughed and lightly patted her tummy "And the burritos have yet to kick in. I almost can't wait"

But instead of ripping another one, Lillian clenched her extra thicc cheeks, wondering if she could feel you more like Jen had done while squeezing her chest and she was very pleased with the result, unclenching and clenching her huge booty to feel you engulfed by her overbearing flesh, sending pleasurable tingles all over the vast, round expanse of her cheeks before the tingles traveled up her back and spread all over the rest of her nerves.

In addition to the much greater weight pinning you in place, another proof that Lillian's gigantic ass was so much bigger than even Jen's gargantuan boobs was that the noises from the outside were nearly completely muffled and even her conversation with Jen was difficult to listen, only being able to make out a few words per sentence. This monstrous booty made for near perfect soundproofing, cutting you off from the outside world and confining you to a noxious, dark one, filled with terrifying storms that were more akin to full blown nuclear wars.

Lillian then began to swing her hips, feeling you bouncing and getting jostled between her immense, plump and juicy glutes. She wondered if Jen could bounce you like this in her cleavage, she certainly tried but she could only make guesses on what that felt like. But she felt like her version was the superior one and the more pleasurable. However her belly was quick to rumble and remind her that she still had a lot of held-in farts that needed to be blasted out.

She let this one charge up, feeling the gas bubbles rushing down her gut, fusing with other bubbles as they began to get cramped, making the nauseating gas within them become increasingly pressurized. She was sure that you were hearing the massive gurgling groans since you were so close to the source and could only giggle when picturing your reaction. She soon felt the swirling winds gathering in the lowest part of her gut, exerting pressure upon the fleshy walls that imprisoned them, demanding their release.

Lillian bit her bottom lip and barely relaxed her "backdoor" when a tremendous blast erupted viciously from the depths between her humongous cheeks, making a reverberating, blaring roar that also made them clap thunderously over and over, adding an ominous boom to the already catastrophic noise while the biggest and strongest gale of hot, heavy and reeking winds hit you head on. Your body shrank down more noticeably, and worse still, this was merely the first of an absolutely massive barrage that she was just starting to unleash, shrinking you more with each nuclear-like blast...

But how much did you shrink by the end of it?

[Paths]

1) You shrank down to about a single millimeter tall, or about 7/100th of an inch, more or less 2,000 smaller than your full size. Lillian dug into her massive ass and picked you up with relative ease, pulling you out of her reeking chasm. When she brought you to her eye level she had an impressed look.

"Wow, I guess those little farts still did a number on you" She said. You shuddered upon hearing that. Those monstrous nukes were small?! Then again, this is Lillian we're talking about, and usually she doesn't mess around with that kind of statement.
"I wonder... is this really your limit? Or maybe this is just how far these farts will get you? It's still gonna be a while before the Salsa Shack burritos give me some real gas" She said, giving you a teasing smile that made your blood run cold.
"Anyway, it's about time Jen gets a turn"

"What?!" You hoped that this would be the end to this madness, but Lillian gleefully walked a few steps and dangled you above Jen's ginormous behind. Even if it looked small compared to Lillian's, it was pretty damn huge in its own right, and even more so at your greatly reduced scale.

"Poor Jen is feeling a bit bloated and she's hardly let anything out" Lillian said.

"She can let them out! Just not on me!" You desperately tried to wiggle free from her grasp to no avail.

"Yeah but where's the fun in that?" Lillian smiled "Besides, you told her you didn't mind~" She said in a mock admonishing way, playfully using your own words against you, although taken out of context with extreme prejudice.
"I think you reached your limit already so you'll probably stay the same anyway"

Jen then gave her hips a wiggle to entice you, her red thong bottom was disappearing even more and more into her deadly chasm of a crack.

"Come on, you let Lillian rip so many huge ones on you already" Jen said, sounding like she was pouting "I just need to let one out"

Lillian gave her a look that only could mean that she wasn't buying that one, prompting Jen to giggle.

"Okay, okay, maybe I need to let out a few" She said while reaching back to pick out her deeply wedged thong.
"But at least they're nowhere near as bad as Lillian's"

This time, you and Lillian looked at each other, your eyes were full of dread while Lillian was simply giving you a smug, teasing smile.

"Of course, mine are way worse" She said with a wink before pulling Jen's thong back and dropping your diminutive form in, dooming you to a terrifying, poisonous nightmare of a fate...

2) Much to your horror, you shrank so small that Lillian's fingertip alone was as large as a skyscraper, and said finger picked you up with ease. You felt an intense upwards motion before you found yourself standing before one of her eyes.

"Holy shit, that's frickin' small!" Lillian said with an overly enthusiastic tone, quickly lowering you back down close to one of her now monstrously gigantic cheeks "Whoa! You make my fat ass look like an actual planet!" She giggled. Jen, who was also looking, was very impressed by the sheer difference in size between you and Lillian's humongous, blubbery round expanses she called asscheeks.
"Well, more like a pair of twin planets" Lillian snickered "And you know what? They might as well be. They're gonna be your planets at least for the time being"

"Wait, what?!" You screamed in terrified disbelief.

"You're too small to understand what you're saying, but those noises were adorable!" She cooed "Anyway, this is gonna be the safest place to keep you since you got so small, so you better get used to these planets of mine. Fair warning though, they're gas giants" Lillian chuckled at her own joke as she nonchalantly pulled her thong back and dropped your speck-sized form in, then letting the thong snap right back in place before unleashing a 20 second long thundering methane monster.

"Just you wait for the burritos to kick in, those are gonna be the real farts" She teased with a smug smile "And I'll get to rip every single one of those on tiny ol' you" At this point all you could do was shudder in fear of the impending cataclysm...
