don’t know if you’re taking prompts at the moment, but here’s one i thought you’d nail: a smutty influencer is recording one of those poorly acted “i can’t get my pants over my fat ass” videos, but to his disbelief and chagrin, his ass starts growing until he genuinely can’t put his pants on and it doesn’t stop there
ok so I actually love this trope!!! There's a similar one that someone sent a while ago about a streamer experiencing out of control growth induced by tips. I couldn't quite get an idea formed, but this sparked immediately. I liked doing the little backstory, I'm a big fan of coming into your own body by being playfully slutty online
[ ass expansion // bubble butt ]
For anyone casually perusing their algorithmically provided content, the Live feed of Ben in nothing but a tank top and some designer briefs would be enough to cause at least a temporary pause in someone's morning scroll. For his followers, the short, telling description at the bottom promised something much more titillating.
A few times a week, when he had a cute outfit in the works and was in the mood for a boost in attention, Ben would do a Live of him getting dressed, inviting the audience into a group conversation about the fashion choices for that day as he coyly showed off his thicc build, starting, of course, in nothing but his undergarments. This morning's bikini briefs were sponsored by a gay athleisure brand who specialized in emphasizing the curvature of the male form.
"I think these are still on sale," he said to his burgeoning audience as he turned his backside to the camera. "Y'all behave, okay?" he smirked at the camera, peering at the growing stream of comments. "Don't want to get banned from Live again," he winked. "But they make your butt look great, right?" He laughed.
The fit of the briefs really were flattering. But as thousands of viewers were coming to realize, and many more thousands of followers were already aware, Ben's butt would look great wrapped in a loose trash bag. It wasn't so much that the fabric accentuated his curves, but struggled for dear life against a pair of round melons that had stretched out, torn through, and otherwise bested all manner of menswear on and off camera. He was stacked.
Ben, for the longest time, had hated his big ass. Disproportionately large and delectably bubbly, it was the first thing you noticed about him and the last thing that stayed on your mind. His cheeks had ballooned into a massive muscle butt in his college wrestling days, making him the constant target of mockery, lust, or some mix of the two. Things only got worse through his 20s, as his comfortable nonprofit accountant job with a generous work from home policy caused him to pack on some pounds, forming a slight chubbiness that seemed to concentrate more than anywhere else in his already intimidating posterior. His otherwise athletic frame had taken on a flattering layer of padding that emphasized the curves of his musculature, none more so than in the dumptruck he was cursed with lugging around behind him.
His ass was a nuisance, if not a constant point of self-conscious frustration. It hadn't occurred to him that he might actually enjoy the attention his caked up backside drew until he started posting online. His page was mainly short slice of life videos, cute photo sets, and progress updates on creative projects for his friends and whoever else wandered into his meager following. It was never meant to be anything special, until, during a sped up video of him assembling a limited edition model kit of a decades-old giant robot anime, he forgot to fully crop the part where he got up to run to the bathroom, leaving his small viewership with an accidentally revealing angle of him in a pair of skimpy gym shorts hugging a divine peach that filled the screen for barely a second.
That was all it took for the video to go viral, followed by a spike in views for every other video in which he inadvertently flaunted his bubble butt. He didn't know what to make of it. He didn't see himself as any sort of influencer model type, especially not with the oversized wagon he was draggin'. But as comments flooded in, he decided to have fun with it, making response videos of him jokingly turning around in all manner of shorts, slacks, and jeans, racking up more views that he ever imagined. What performed better than anything else was a running gag in which he struggled to pull his pants up over his substantial glutes, frowning behind him as he comically yanked the over-stressed waistband, causing his cheeks to jiggle uncontrollably in front of the camera as they bubbled out of the fabric.
If people liked his butt, so be it, he thought. As his following grew into the thousands, then hundreds of thousands, his content coyly flashing his bodacious buns began to get more bold, more playful. He became more comfortable showing off his body, experimenting with cute dances, self-deprecating yet body positive leg day workout voiceovers, unboxings of menswear that turned into sponsorship deals, even a line designed for men with his particular disproportions, and eventually, smutty content that hinted at even smuttier paths through the link in his bio. So one lazy morning, he had some time before he had to head to the office and some conflicting outfit ideas, and decided to jump on Live and pretend to be a fashion influencer for a quick #GRWM.
"Okay, are we thinking the polo or the button down?" he asked, holding two options in front of the camera. "I've been really into collarless tops lately."
"Ain't nobody thinkin' about that shirt," he muttered aloud from the comments before bursting into laughter. "Y'all are impatient today," he teased, tossing the shirts aside. Checking that viewer numbers were sufficiently high for the main attraction, he snatched another sponsorship deal from off camera, this time from a menswear brand pushing their super stretchy business casual athletic fit slacks.
"You remember what happened last time we tried those 'super stretchy' jeans," he rolled his eyes, "but these are actually so dope. Super comfy and they fit like a glove."
His brief-clad bubble butt ballooned towards the camera as he bent over to slip into each leg. His cheeks wobbled and shook in protest as he tried to get them on, the seat of his pants slowly making its way upward. He made a show of jumping up and down, which only served to send waves of reverberation across his oversized ass. As promised, they hugged his prodigious backside like a second skin.
"These look great!" he exclaimed, turning to each side profile to see his meaty cheeks and tree trunk thighs from multiple angles. "Looks heavy," he read from the comments as he turned back to face the screen. "And getting heavier," he chuckled, playfully jutting one of his globes toward the camera.
"Soooo thicc, you can see it from the front..." he read another. He laughed it off, innocently holding his arms out as he backed away to get more of his body in frame. "It's way too early for this..." he trailed off, his eyes bulging as he noticed the curves of plum colored fabric expanding on either side of his hips. "I, um..." he stammered, his face tilted in confusion as, even though he was standing perfectly still, the globes of his ass looked like they were slowly filling more of the space behind him. An anxious twitch of his glutes brought him back to reality, his pants suddenly feeling acutely, uncomfortably tight. "...went way too hard on leg d--" he was cut off by the soft staccato of seams failing and the sudden presence of cool air across his cheeks.
"Ughhh, these barely made it thirty seconds," he groaned, turning his back to the camera to show the tattered remains of the seat of his pants, his ass bubbling out between them. Comments, tips, and rewards flooded in at the incredible sight, but Ben couldn't keep his eyes off the pair of beach balls he called an ass that was reflected back to him on camera. It wasn't just that his butt looked big (this wasn't the first fashion faux pas he'd had on camera), it looked too big. Bigger than anything that could've fit in those pants while still obeying the laws of physics. And it looked like it was getting bigger still. "I...think they sent some larger pairs!" he suddenly remembered. His gait seemed off as he strolled to the other side of the room, cheeks wobbling back and forth heavily enough to throw him off.
He kept talking about his day as he searched his closet for the backup slacks. He was thankful he remembered to clip his mic so he could fill time with his big presentation coming up at work, his latest takes on the shows he was watching, upcoming brand deals and collabs. Yet all anyone watching the Live could pay attention to were the gargantuan globes steadily ballooning from his lower back. They swallowed his briefs completely and pushed his ripped pants aside like an afterthought, the absurdity of the situation only becoming more apparent as their growth picked up speed.
"Found 'em!" Ben exclaimed. He held up a similar looking pair of plum colored stretchy slacks as he turned around and headed back to the phone mounted on his desk. "I always have them send some larger pairs just in case. You know how...it..." his jaw dropped at the sight before him. If his ass had been visible from the front, it was now undeniable. He looked awestruck as he turned to the side, unable to process the fact that his cheeks had somehow tripled in size since he'd started the Live. "What the fuck," he whispered, leaning in to read the deluge of comments, as if some random person out there might have some ideas as to how his ass had grown to a size that shouldn't be physically possible and wasn't showing signs of slowing down.
"No...it's not AI," he muttered, responding to what comments he could glimpse before they were swept away. "No, there's no filter on. I don't know what's happening, okay?!"
He felt dizzy. His composure was breaking. He grabbed the arms of his gaming chair and guided it behind him, struggling to shove himself into the seat as the chair groaned in terror. He kept adjusting and readjusting his position, grimacing as his cheeks spilled out behind him, growing more massive than anything the chair was designed to hold.
"Guys, this is serious!" he yelled, frantically typing on his laptop while keeping on eye on his phone. He felt himself starting to panic, tentatively touching his growing backside to verify that it was real, wincing every time he felt his globes lurch to an even larger size. How could this be happening. How was this possible? "No really, it's not a prank, I don't know what's--OOF!"
The chair failed catastrophically under his monumental cakes and he hit the ground with a thud loud enough to be picked up through his mic and heavy enough to knock his phone out of its mount.
The Live was still going. Now angled from the floor, viewers were treated to the sight of Ben struggling to stand, his sofa sized cheeks swishing wildly back and forth as he attempted to run out of the room, only to get stuck in the doorway, the massive bubbles of his glutes producing webs of cracks around the door frame.
Eventually he gave up and stumbled backward. As he frantically scanned the room for his phone, his cheeks were knocking things off of shelves, which only served to worsen his anxiety. He was too big, with no explanation and no means of escape. He fell to the floor as he reached for his phone. He clutched it in his hands for dear life, hoping to call for help but instead getting caught up in the sight before him.
Reflected back to him was the still active Live showing his terror struck face. He was framed by mountains of blubber buns expanding behind him. He wouldn't have been able to accept the monstrosity as his own ass if not for the feeling of his cheeks pushing against furniture and the sounds across the room of wood and plaster cracking and warping under the relentless pressure of his growing booty.
"H-help...?" his voice cracked as his ass filled the screen, dropping the room into darkness as it eclipsed the windows, leaving only the steady stream of confused and enthusiastic viewer engagement.
