[Chapter translated to English by Random Anon]
Bertha walked out of the bathroom to go back to her daughter, giving her massive booty an extra bounce to get a feel of your diminutive body engulfed between her enormous, jiggling cheeks in spite of how small you'd become.
Inside the depths of her ass you were indeed thoroughly enveloped by two gigantic oceans of fatty flesh that bore down on you with the weight of several planets and in addition to that there was that wrinkly rubbery ring that seemed to hunger for you. Suddenly, these gargantuan fleshy masses began to bounce and jiggle frantically, indicating that Bertha was walking, on her way back to her spot with Snickers.
"Mom? Did you have any luck finding Blaise?" Snickers asked worriedly as she hadn't been able to find you yet.
"Oh? Don't worry about that anymore, dear" Bertha nonchalantly replied "He's in good hands now~" She said in an attempt to calm her daughter down.
"W-What do you mean he's in good hands now?" Snickers' concern spiked, knowing her mom's particular history not being the most careful person out there in spite of being a friggin cop whose job was supposed to be to keep the school safe.
"What I meant was that he's back with his friends, they helped me look for him when I was in the bathroom" Bertha nonchalantly explained, her voice and attitude didn't help reassure Snickers at all, getting a feeling that there was something off about the whole situation.
Though on the other hand, it actually fit quite perfectly with Bertha's carelessness to have had the two girls walk in on her while she was searching her ass and Snickers wouldn't put it above Bertha to just randomly blab out about the shrunken guy that was lost in said huge ass.
"Are you sure mom?" Snickers decided to press the issue, looking her in the eye.
"You're not lying to me to get away with whatever you want, are you?" She asked bluntly, knowing her mom many times deflected questions or went off-topic unless she insisted in pressing a specific matter.
"No...t this time" Bertha said, adding the rest as she saw the skeptical look in her daughter's eyes, huffing annoyedly even though she was indeed right to not be too trusting with her, that could prove to be a thorn on her side later on unless she nipped it in the bud early.
"Look, I know what you were thinking but his friends were really looking for him and ran into me when they went to the bathroom. They caught me in fraganti so it was no use lying, they helped me find the boy and took him back, I didn't have any excuse to keep holding onto him" Bertha explained, surprising even herself a little with how well she delivered those lines.
"You think I can't take things seriously when needed, don't you?" Bertha then said, still in an annoyed tone when suddenly a massive 10 second-long bassy fart erupted from her enormous rear end.
"See? If your little friend were back there I wouldn't have let out that little toot" Bertha chuckled, trying to mask the fact that she did enjoy not just how her jiggling cheeks rumbled but the fact that she could even slightly feel that your diminutive form tickled the inner side of those cheeks, which turned out to be more sensitive than she thought.
"Okay, sorry mom" Snickers sighed, that sounded and seemed sincere enough. Her mom could be bad at times but surely she wouldn't be downright evil so as to kidnap an innocent guy right? "I just thought it was a little odd you managed to find him at that size"
"Yeah, if his friends hadn't helped I wouldn't have found him until much later" Bertha laughed a little. At that moment, Snickers' stomach growled quite loudly, indicating that in spite of her continuous snacking she was hungry as it was around this time of the day that she usually ate a proper meal.
"Uh, wanna grab a bite?" Snickers then asked, looking bummed out that you weren't with them anymore though she tried to hide it, not enough for Bertha not to see through.
"Sounds wonderful!" Bertha smiled, feeling quite hungry herself but she was more excited about the fact that a few hours after having food her already tremendous farts would be even bigger and way more abundant, craving to feel more of you vibrating between her humongous cheeks. That'd definitely be the worst possible outcome for you if you failed to escape from her monstrous ass.
Down in the dark depths of said ass you noticed that the swinging motions stopped, although the immense blubbery masses jiggled for a while after, jostling you in between. This likely meant that Bertha had arrived to her next destination but you couldn't tell for sure what she was planning, for it was impossible to listen in on the outside sounds, as her overbearing amounts of fatty flesh muffled all those sounds into oblivion. However you knew one thing for sure: You'd have no peace as long as you remained trapped here, as she wouldn't hesitate to unleash her huge farts upon your now very diminutive form.
Pressing the side of your head as deeply as you could into the gelatinous flesh of one of these gargantuan planetoids you managed to hear bits of Bertha's conversation and while you couldn't get everything, what you heard was enough to piece together that she essentially gave Snickers a cheap excuse for your disappearance, making you not just annoyed but frustrated. The only person who could save you wouldn't even be looking for you anymore!
You decided to try and get away from her asshole, which still pulsated threateningly but trying to move between Bertha's colossal glutes was akin to trying to swim in an ocean of jello. You then heard a very loud, ominous rumbling series of groans coming right from the other side, thoroughly horrifying you as you knew what it'd mean. You frantically squirmed around, trying to get away at any cost but to no avail.
"Please, someone get me out of this hell!" You screamed in despair to anyone willing to listen but it didn't seem like anyone up there in Heaven was paying attention. The only one who'd get you out of this nightmarish prison was the Devil herself, the one who imprisoned there in the first place: Bertha.
The seconds before the apocalyptic explosion ensued were an absolute agony, the sheer feeling of powerlessness overtook your body, you were far too small and weak to get away from Bertha's "line of fire" and as your eyes grew used to the darkness, all you could do at this point was watch in horror how her hungry-looking hole swelled as more and more gas accumulated.
Then there it was, as if time froze for a split second only for it to end with a deafening rumbling roar that sounded like a world-ending storm while a gigantic hurricane of swirling hot, heavy and noxious gases picked you up effortlessly and sent you flying with untold force. Her titanic cheeks made loud booming noises as they clapped to the tremendous' fart's furious reverberations. Suddenly, your movement stopped as you smacked face-first into a wall of taut, black fabric and immediately realized that this was Bertha's badly wedged thong. You held onto it for dear life as the monstrous gassy explosion raged on.
You were absolutely certain that holding to the back of her thong was far better than staying near her hole so you dug into the reeking fabric with all your fingers and toes, determined not to be dislodged by these enormous winds. Time felt like it had slowed down to a crawl but eventually, the 10 agonizing seconds it lasted passed and the roaring storm gradually died down.
'At least I managed to get away from that monster' You thought, taking deep breaths in spite of the atrocious smell that enveloped you. However small it may have been, this was a victory that you earned, holding onto this wall of fabric was a won battle in your book and you were relieved that you didn't fall even deeper into Bertha's monstrous ass, though this stunt took quite a lot out of you.
'Maybe if I can keep holding onto this I can break free when she changes her underwear' You thought, holding onto that hope as well. Any chances for freedom was better than zero. Not that this was the best kind of environment to camp in, specially after that tremendous blast.
What happens next?
