Jen nodded and smiled at Lillian, then she walked over to the chair and stood before you, her now massive body loomed over you in a way that you found deeply intimidating, backing away until the chair's backrest prevented you from getting any farther away. She slowly turned around, wiggling her hips in a clear attempt at making this enticing for you.
"Well... now I need to let one out..." She said in her usual cute voice "You're still okay with that, aren't you?" She looked down at you from over her shoulder, and even with just one eye she was giving you a sort of playful look that only made you increasingly nervous.
"J-Jen plea-"
BOOOM!
Jen's humongous derriere plopped down with a deafening booming noise as the hefty weight of her curves hit the chair, making it creak and groan although not as much as Lillian would have. She wiggled on her seat and you were unsure if she was getting comfortable or if she was trying to give you the world's most dangerous lapdance. Perhaps the biggest irony in there is that you only learned what a lapdance was because of Lillian herself...
You terror hit through new ceilings. Getting blasted by Lillian's devastatingly huge farts over and over was already way more than just bad enough, but after having been hit by the smell of just one of Jen's you knew that it was going to be far, far worse than anything Lillian dished out so far, plus you were even smaller and more defenseless now.
You got startled when you began to hear terrifying rumbling groans that were clearly coming from Jen. Those noises easily gave Lillian's a run for their money! Imagining farts as massive as Lillian's with the sheer toxic reek of Jen's and shrunken down to roughly 1/100th of your normal size made this a perfect recipe for disaster, with you on the receiving end. While you were deep in your doomed thoughts, you failed to realize that to any outside onlooker, it appeared that you were staring intently at Jen's huge ass, which made both girls giggle. Jen herself gave you a playful wink and a smile that made you wonder what she could possibly mean now.
'Told you he really likes your booty' Lillian said nonverbally with a few glances at Jen, her butt and yourself.
'I thought he was going to be scared' Jen replied, also nonverbally, simply through a few glances at Lillian, yourself and some shrugging among a few other things. Seeing your positive reaction to her, she decided to "reward you" by giving you a bit more of a show, slowly grinding her butt on the chair's seat so you could watch how it jiggled and bounced softly as well as how it compressed while she remained seated. While not as tremendously massive as Lillian's, Jen had plenty of cushion back there to render pretty much anywhere a comfortable seat.
Getting a naughtier idea, she began to stand up, which confused you. You wanted to be relieved, that maybe it was all just some stupid prank, that she wasn't planning on unleashing her nightmarish farts upon you. You saw that building-sized booty rise off the beach chair, which was already large enough that it was a struggle to comprehend how much space it was equivalent to in your scale.
But, as it often is the case, things were only going to get worse. Jen giggled and scooted backwards, bringing that big, ominous ass even closer to you, dangerously close as it plopped down just like the first time, making for another immensely powerful shockwave with an even more threatening sounding...
BOOOM!
Your immediate surroundings quaked like never before and you got knocked off your feet, unable to stand back up until the tremors died down. Your heart began pounding harder while your limbs, specially your hands, twitched from sheer desperation. At this moment, somehow, you felt like you would've been better off getting farted on by Lillian again.
Jen's huge ass barely left a tiny sliver of space between itself and the backrest, having you completely trapped, with no possible escape route, with nowhere to go. You stood right before her crack, which eagerly devoured her red thong once more and was definitely more than large enough to swallow you, should you be unfortunate enough to fall in there, a thought that sent more cold chills up your spine.
As if on cue, the ominous, deep, rumbling groans returned and began to grow louder with each passing second, striking fear deeply into your heart. And Jen herself kept wiggling and shifting on her seat, making minor tremors that only made everything else seem far scarier.
"Jen!" You tried to shout, but unknown to you, at that moment she was already focused on her inner feelings.
Her gut was bubbling like a boiling pot as deadly, toxic gases swirled and their pressure increased, making her feel even more bloated. Under normal circumstances she would've held it all in even if it hurt her tummy, the only way she'd let one out would be entirely by accident. But not today, today she was filled with curiosity, instilled by Lillian, wanting to find out how much smaller you could get. Plus, everything Lillian had told her about how much you liked her luscious rear and that even the idea of her farts wouldn't turn you off them ended up coming true and she wanted to push those limits. She'd already had some fun using her prodigious chest but what she really looked forwards to was to using her big ass.
"Jen! Please, don't-!"
You gut cut off by a truly monstrous explosion that erupted from the gigantic booty sitting right before you, blasting you with a thunderous roar that blared furiously in deafening, repeated soundwaves that felt more like shockwaves that rattled your bones as they blew past you. You were immediately caught in a colossal, tornado-like swirling torrent of thick, hot and somewhat heavy mixture of deadly gases that had been thoroughly fermented in the darkest recesses of her gut. The plastic wall that was the chair's backrest provided no relief as you got pressed into it by the oppressive force of these furious winds that violently forced their way up your nostrils and even your throat, making you feel like they burned badly.
Said burn completely outclassed the deafening, booming bassy blast that you just endured, or even the painful pressure of her fierce winds as they pushed you into the cold, rigid backrest of the plastic chair, ironically warming it up dramatically with its excessive heat. You began sweating and your vision went dark for a moment. But then again, the burn on your nose and throat managed to overwhelm everything else, and all of these previous things would've been able to overload all of your senses on their own.
Your body felt surges of intense pain as Jen's highly toxic gas spread from your lungs across the rest of your body, you fell to your knees and writhed miserably, so much that you didn't even notice the feelings that preceded your shrinking, nor did you realize how much you had shrunken until the nightmarish burst finally died down and you laid for what felt like several minutes.
As soon as your eyes regained their focus, you felt like fainting, holding onto your consciousness by some miracle. Jen's huge ass, already larger than many of the largest buildings you'd seen except skyscrapers, looked way bigger, like a pair of mountains and her crack looked even more like an ominous, canyon-sized chasm where you'd easily get lost if you were so unlucky as to end up in there.
The vicious stench of Jen's fart felt as if it held you down with the force of a heavyweight wrestler, keeping you immobile against your will 'H-How do Jen's farts smell this horrible?!' You wondered, as the toxic mixture of an overwhelming reek of beans with touches of spoiled meat. You then shook your head, realizing that there was a much more important concern: You shrank a lot more than when Lillian blasted you with what you thought were some of her worse farts. This was quickly getting out of hand.
Jen giggled cutely, sighing in relief after letting out one of the biggest farts she'd ever unleashed. It was clear that she had absolutely no idea of how terrible that terrifying monster of a fart had been.
"Whoa, I didn't think it'd be so big" She said, lightly patting her rumbling tummy, an inoffensive action that turned out to have been a mistake, or at least, it was for you, as even that minimal patting was enough to dislodge many smaller bubbles of highly pressurized gas that had gotten stuck along the way and were gathering as more bubbles reached them and fused together.
Jen was amazed that she'd finally been able to go and rip one, right on you. Not that she had a thing for it like Lillian, though, after seeing her doing it so many times and with such freedom, she got curious. It was like a weight had been lifted off her shoulders, she wouldn't have to worry about eating her favorite foods while around you anymore.
"I need to let out some more" She said, in that same cute, adorable voice that now instilled a new level of terror upon you.
"Wait, Jen! Stop!" You tried to scream but were once again cut off by a tremendous blast that hit with the force of twenty typhoons and whose blaring, bassy roar was louder than several thunderstorms. Her raging winds once again slammed you into the backrest and forced themselves into your throat and nose as you shrank more while reeling in pain.
And as soon as that one ended, she hit you with another one, this one felt more akin to taking a volcanic eruption to the face, as the hot, toxic gases that rushed out at insane speeds also engulfed you into a nightmarish cloud that made you sweat almost as if you were in a sauna, shrinking smaller still.
Despite the overbearing stench that only Jen herself appeared not to be aware of, Lillian observed with amusement as her friend suddenly began to unleash an enormous barrage of massive farts that could almost compete with her own on nearly all aspects while dwarfing hers in smell. She smirked as Jen's huge booty blasted fart after fart upon you, shifting some more in her seat, looming even closer and closer for each blast...
How much did you shrink by the end of this terrible nightmare?
