The unexpected explosion and both the shockwave that ensued as well as the sudden quaking that it caused upon the wobbly ground you stood on flung you away, fortunately away from the abyss you were trying to get away from, landing face-first on more of this bizarre, caramel-colored doughy mass, though now you also felt a bit of a salty taste.
You stood up once more but you had to try and cover your nose with your shirt, a powerful stench lingered though not an entirely unfamiliar one. You knew that volcanoes often had sulphur, and that such a material had quite the potent smell but as you'd never been close to any in real life, experiencing it first-hand still hit way differently from just knowing about it. However, the smell assaulting your nostril didn't feel 'chemical', it felt like it was from a more natural or, well, organic origin...
'I must be starting to hallucinate' You thought, shaking your head. You tried to get away from the nasty fumes that lingered all around but no matter how much you walked you were still breathing them in.
'It smells like mom's farts... weird' You prayed that whatever this was it wasn't anywhere near as toxic as either of the possibilities. Then again, you had quite a lot of exposure to your mom's over the years, in theory you should have some degree of resistance. You chuckle, reminding yourself that you should be more worried about it being actual sulphur.
"Good one! But isn't that a bit much?" Sheila asked in the group chat, earning some silent giggling from both her friends who saw the absolute irony.
"I didn't mean to, it slipped out when he tickled my crack" Miriam replied. She was very quietly cooing as she saw you through Zuleima's stream. She couldn't help but wonder how you hadn't recognized her fart.
'He has to know it was me. But what is he thinking right now?' She thought, watching as you resumed trying to get away from her crack while also struggling not to breathe her lingering blast too much.
"So, what now? Are you gonna tell him yet?" Zuleima sent. She was in no particular rush but she was also curious, both about your reaction upon finding out the truth and to see how much more playful Miriam would get once you did.
Rather than writing an answer, Miriam simply replied with a cheeky smile and a sudden, sharper wiggle of her hips, sending her plump asscheeks into a renewed jiggling frenzy. Her smile widened when she felt your diminutive form getting flung towards where she wanted you, her crack.
"Wha-!" It was as if the whole world moved at once, an unbelievable force shook the squishy gelatinous ground beneath your feet and before you knew it, you were once again flying towards the deep, dark abyss. Your eyes widened in panic, you tried to flail your arms and legs in an attempt to steer your course but it was all to no avail, you were heading down the gigantic yawning chasm below.
This time, there was no escape, no way out, you simply kept falling and falling as your surroundings grew darker. But before it got too dark, weirdly enough you saw a large strip of red at the very bottom, almost like some kind of river, though the red color itself was too bright to be something like blood. In fact, it looked more like some kind of cloth, and it even seemed to be a bit moist.
The feeling of vertigo was unlike anything you'd experienced before, you had never done anything remotely close to bungee jumping but this was definitely more extreme, you felt as if you were falling for miles upon miles, the cold air chilling your skin but at the same time, the atmosphere surrounding you felt increasingly warm and steamy. Your senses went numb after a bit and thus, you didn't even realize that you were going to land soon and smacked into the ground with a slight 'SQUELCH!', the ground felt like slightly moist fabric indeed.
Immediately, everything began to shake from side to side, making you bounce between the insurmountable-looking walls at your sides, a pair of gigantic round masses larger than any sort of mountain you'd ever seen in person. You slammed into the both of them repeatedly and mostly face-first. Thankfully, they were just as doughy and squishy as the ground from earlier and it was like laying on a whole bed made of pudding or jello.
Outside, both Zuleima and Sheila nearly snickered, watching your descend down Miriam's massive asscrack and as soon as you hit the bottom, she shuddered and some goosebumps formed on her back and arms. She happily wiggled her hips and quietly hummed to herself a happy tune, the other two ladies knew that she had just accomplished her goal though they believed she would've revealed the situation to you before going for it.
"Welp, as if things couldn't get any worse" You sighed, groaning in frustration. Before, you were stranded on a bizarre landscape. Now, you were trapped in some sort of gargantuan ravine. The only positive thing was that you were finally in the shade, no longer under the scorching sunlight but at what price? The immense mountain-like things at your sides were far too huge to try climbing, plus you didn't even have any gear or supplies. Just like the surface, the landscape here seemed rather barren, with no other signs of life other than yourself.
The red fabric you stood on felt more or less artificial but at this point, was it really that much weirder than the squishy, jiggly caramel-colored mass from before? You couldn't tell what kind of material that was, no rock or mineral felt like that, if anything it felt more like living flesh. Seeing that you could only walk straight ahead or in the opposite direction, you decided to start advancing towards the front, hoping to get anywhere meaningful.
A mere few steps in, the titanic wobbling walls at your sides abruptly closed in on you, slamming into each other while engulfing you into their overwhelming bulk. You felt as if you were submerged in an ocean of warm jello, with some hints of salt and moisture added. The 'walls' then let go of you, only to close in on you once more, contracting and relaxing repeatedly, almost with some rhythm of its own.
"Wow, you were right Zuleima. It feels really good, he's walking around in there" Miriam typed, giggling excitedly, hoping that her ample cheeks provided some measure of soundproofing from the outside.
"But it sucks that we can no longer see him" Sheila noted as Zuleima closed the stream, there was no way that her phone's camera could reach between Miriam's cheeks without making it blatantly obvious but based on the last they could see, they could picture the sort of 'landscape' that you'd encounter. They also noticed how Miriam was repeatedly clenching her big booty in delight.
"Now what, Miri?" Zuleima texted with a slightly smug look, wondering what would be Miriam's next course of action but already having plenty of fun watching her antics. The original plan back when they first thought about it had been drafted with your father Raphael in mind, but given his lack of availability due to work, Miriam decided that it was best to have you instead, plus, she didn't like the idea of her friends getting too playful with her husband.
"I'll reveal the surprise soon, for now, just let me enjoy this" Miriam texted before putting her phone down, sighing in pleasure and closing her eyes, focusing as much as she could on her butt and every sensory input coming from it. Your tiny footsteps, the way your body got engulfed between her cheeks every time she clenched, the increasing excitement as you were unknowingly approaching a very particular spot...
You had no idea for how long you'd been walking, the repeated closing and opening of the meaty walls surrounding you made things seem a lot slower. You wondered if this was some odd kind of dungeon, because it seemed like you were setting off traps, though you couldn't see or find anything, just the red fabric the ground seemed to be made of and the strange, doughy material of the walls themselves. After an unknown amount of time, you noticed that for the first time, the terrain changed, before you, the ground seemed to raise a little, there was a noticeable, large bump of sorts in the terrain. Still covered by the same red fabric, but it was stretched more taut around it.
You kept walking and gradually got nearer and nearer, feeling that it was radiating off more warmth than usual but in addition to that, it gave off a surprisingly powerful smell. The same kind of smell you felt earlier when there was that enormous explosion.
'A geyser?' You wondered, still approaching it albeit more cautiously. Looking around, it seemed that this odd bump had a circular shape, its diameter being roughly 10 times your height or so. Given the smell, you were inclined to believe that the apparent volcanic eruption from earlier most likely came out of this thing, but it was strange, there was a whole layer of fabric over it, making you scratch your head in confusion.
You then reached towards it, with a measure of morbid curiosity you touched it with your hand and you could feel that beneath the fabric, there seemed to be some sort of rubbery material. But as soon as you touched it, the whole thing began to pulsate rapidly, as if trying to break out from the fabric keeping it contained. The sudden action made you jump backwards in surprise, afraid that you'd trigger another massive eruption.
"Miriam is enjoying this way too much. What is he even doing down there?" Sheila texted the group.
"Whatever it is, Miriam likes it for sure" Zuleima noted as their friend was smiling, even blushing a little as she happily swayed her hips. She looked as delighted as when you were massaging her back and butt before.
You looked around and there didn't seem to be much space, if you wanted to proceed further ahead, you'd have to climb this mysterious geyser-like thing. Would you brave it or would you turn back and try going in the opposite direction?
