With the constant movement from the massive walls at your sides, it didn't seem like it'd be a viable option to try and go around it, and turning back felt like you'd be wasting your effort. Besides, what if there was another geyser-like thing, or even more than just one?

You were a bit nervous, you didn't want to be too paranoid but it almost seemed like the thing in front of you had reacted to your touch and if you'd have to climb on it in an attempt to get past it, who knows what might happen? You shook your head and sighed in frustration, you were still wracking your brain trying to make sense of everything, because nothing did so far. The bizarre ground from before, now making the enormous walls that kept you confined, the odd watery blobs that randomly emerged from the ground, the inexplicable quakes that were the very reason you tumbled down this yawning abyss and the dark chasm itself, nothing added up to anything you ever knew.

'Guess it sucks to be dumb. Maybe if I were as smart as Zuemy I would've already figured this one out' You thought and then focused back on the issue at hand, the dangerous-looking bump you'd have to climb on and then try to run across it as fast as possible before anything terrible happened. It seemed quite straightforward in your head but you were afraid, there were so many things that could go wrong, plus you didn't even fully trust yourself.

You decided to get close once again and to try touching it to test whether or not it was really reacting to your touch or you were simply unlucky with the timing. The moment you put your hand on it, it immediately started to pulsate rapidly, startling you even more than before. In addition to it looking rather freaky, the warmth that it gave off was even greater than what you felt before, giving you the impression that this thing might be alive.

'But that makes no sense' You thought, slowly approaching to try again. Very carefully, you lightly put your hand on the 'bump' in the terrain and just as the previous two times, it immediately twitched and pulsated very rapidly.
'Holy hell, is this thing really alive somehow?' You felt your heart skip a few beats and then trying to jump up your throat. What the hell kind of Eldritch abomination of a world was this place?

'Wait, maybe it's not alive. But it could be reacting to stuff like my bodily warmth' You thought. That made a bit more sense than believing that this odd terrain feature was a living thing but at the same time you knew you were grasping for straws. You forced yourself to try again your impromptu experiment, reaching towards the large terrain bump and putting your hand on it.

As soon as your hand touched it, the whole thing resumed twitching and pulsating with increasing intensity, however, this time you didn't back away, trying to wait it out. If it was a simple inanimate thing reacting to your body heat, then it would eventually stop once your hand cooled down enough, though on the other hand, this thing seemed to irradiate a warmth of its own, it wasn't cold like you'd expect a rock or the ground to be.

Instead of calming down, it seemed like things were getting more chaotic, you felt as if the entire world shifted from side to side and soon the gigantic gelatinous walls that kept you in darkness closed in upon you as they had done earlier, pressing you in between with even greater force though they were still far too soft to hurt you in any way.

Outside, Miriam was giggling as quietly as she could, happily wiggling her hips and clenching her sizable asscheeks repeatedly. Both Zuleima and Sheila noted that she was doing it faster now just as the intensity of her giggling became such that she could no longer fully keep it silent but she was trying hard to.

"What's going on?" Sheila texted. She was tempted to speak but she chose to respect Miriam's wish still.

"It really tickles, it feels so good!" Miriam responded, visibly having some difficulty to type on her phone. "If I didn't know better I'd think he's massaging me on purpose" She added. Sheila turned to Zuleima and raised an eyebrow, silently asking her what was possibly going on.

"If my theories are correct, he must be swimming between Miriam's cheeks. Imagine trying to move while sandwiched by two huge waterbeds, that's the closest approximation I can give. If he's trying to move around, he's probably using swimming motions and I assume that's what's tickling her" Zuleima wrote.

"Ha! You finally can't deny that your badonk got flabby" Sheila texted but as soon as she did, both Miriam and Zuleima were glaring at her with an eyebrow raised, the universal look of 'Really?'.
"I mean, I've never denied that my curves are pretty squishy but a certain little lady in here keeps insisting that she doesn't have a fat ass" Sheila typed while giving her friends a cheeky smile.

'Ok, not only this thing reacts but the whole ravine too?! What in the Indiana Jones is this?!' You thought while trying to push the overbearingly plush masses off yourself, though it mostly resulted in your arms and legs sinking into them and apparently eliciting even more tremors.
'Well, no use standing around in here, it almost seems like these things want to squash me flat' You then thought and decided to try and push forwards until you found a semblance of an escape before your strength ran out.
'There HAS to be something farther ahead' You told yourself while exerting some more effort to move forwards, with the constant shaking from side to side and the gigantic squishy walls pressing into you making your task much harder. But then, you stopped right where you had before, you were right before this inexplicable thing, like a mound? It wasn't nowhere tall enough to consider it a hill and it wasn't big enough to call it a plateau either, it was only a little taller than you were and roughly 10 times your height across, maybe the size of a small-ish house.

'Whoever is up there above, please don't let me die in this weird world like a dog' That was your attempt at a prayer and then took a deep breath. You grabbed onto the thing before you and rapidly climbed on top of it, once again triggering its twitching and pulsating, like a beast that was waking up. The rubbery material it seemed to be made of was firmer than the squishy masses engulfing you from the sides but it was soft enough to make it difficult to maintain your footing, even more so with its wild, seemingly erratic movements.

You quickly ended up falling face-first on it, further intensifying the rubbery mass' pulsations. You panicked when you felt that something got a hold of your face. This thing was grabbing onto it! You tried to push yourself up with your hands, but those too ended up getting caught between some folds that you hadn't noticed, obscured by the fabric that covered it. Your heart was pounding its hardest, it felt like you were caught in some monstrous maw, sensing danger, that this thing somehow had an appetite and it wanted nothing more than to devour you.

You anchored your feet as best as you could and tried to push yourself up, mostly with your legs while also trying to free your arms. The harder you tried to push yourself away from this thing's vice grip, the harder it pulled you closer. Your entire self-contained world shook wildly from side to side, adding to the already chaotic mess and just then, you could swear you heard a faint voice, a woman's voice... and she was giggling. But the sound was so muffled that you weren't even sure if it was real or a hallucination induced by the panic, or maybe the lack of oxygen. Your face felt warmer and you figured it must've been looking really red considering that it's being held between some strange folds on this twitching, writhing mass.

Just then, there was another sound, it was low at first but it rapidly grew louder, it was a deep rumbling and along with it, the rubbery mass itself vibrated from its sheer noise. It almost felt like this supposed monster was snarling but it soon it began to sound more like a guttural roar. In mere seconds, the vibrations became so intense that you sensed that something was approaching from below, something massive, something-

It was like in movies or series, it seemed that at that very moment, time slowed down to a crawl before there was a truly gigantic explosion, definitely akin to that of a volcano. A colossal torrent of swirling, blazing winds blasted in your face, blowing you away and taking you along for the ride, going straight up into the air while the deafening roar it made, far mor powerful than any thunderclap, rattled your bones and you even felt it shaking the muscles inside you. You have no idea how fast you were flying, but it felt like you had just become a human bullet.

Those cannonball stunts in the circus got nothing against this. The darkness gradually faded as you reached greater heights, where there was more light but then your ascent was stopped just as abruptly as it had begun. You slammed back-first against a moderately soft but firmer wall, which then seemed to fold upon itself, trapping you.

All the tickling that you'd been unwittingly doing on Miriam's most sensitive spot hadn't gone unnoticed and given her usual diet, plus the burritos that she had already wolfed down caused her gut to stir awake and unleash quite an enormous fart in response. Miriam couldn't help but giggle, finding her mental picture of your experience cute and endearing but she sensed that this was a bit much even for you and correctly guessed that this fart would blow you out of her crack, so she put her hand on it and as soon as she felt you on the middle of her palm, she gently closed it, securing you. She then slowly brought her hand to her face and carefully opened her palm, looking at your diminutive form intently.

"Hi, honey!" She nonchalantly greeted you... What happens next?
