Fanfiction Fridays: Blue Blur about to Burst

Here's the first official entry into Fanfiction Fridays. For this auspicious post, I've decided to write about possibly the most fanfiction'd character in all of fiction, Sonic the Hedgehog.

Station Square buzzed with its usual chaos: cars honking, people chattering, and the distant hum of G.U.N. helicopters patrolling the sunny skies.

Sonic the Hedgehog blazed through the city, a blue streak weaving between pedestrians and lampposts, his red sneakers a blur. The wind whipped through his quills, but his stomach growled louder than the city’s noise.

“Man, savin’ the world’s a lot harder on an empty tank!” he muttered, slowing to a jog. His emerald eyes scanned the streets, hoping for a quick fix to his hunger pangs.

“Where’s a hot dog stand when you need one?” he quipped, throwing up his hands in mock frustration. “I’d even settle for a vending machine…though I don’t think they take rings~”

Then it hit him! Wafting through the air was a scent so divine it stopped him dead in his tracks.

Chili dogs! The spicy, meaty aroma tickled his nose, pulling him like a magnet.

“Oh yeah, that’s the stuff!” Sonic grinned, his mouth watering.

He dashed down a narrow alley, following the scent through twisting passageways lined with graffiti and overflowing dumpsters. The city’s glitz faded behind him, replaced by cracked pavement and flickering streetlights.

His stomach rumbled again, urging him on. “Hang on, buddy, dinner’s callin’!”

The trail led to a dingy, abandoned food stall tucked in a forgotten corner of the square. Its faded sign read “Chili Chompers,” but the counter was unmanned, the grill cold. Yet, there it was…a massive platter piled high with steaming chili dogs, slathered in sauce, cheese dripping over the sides, each bun softly steamed to perfection.

Sonic’s eyes widened. “Jackpot!” he whooped, but his grin faltered. “Then again…this feels like a setup. Nobody just leaves a spread like this out unattended…and uneaten!”

He glanced around, quills twitching, expecting some kind of trap. It wouldn’t be the first time his long time arch-nemesis Dr. Eggman used Sonic’s appetite as the bait for a trap.

But there was nothing. Just the eerie quiet and that irresistible smell.

His stomach growled louder, practically shouting.

“Okay, okay, maybe just one…” Sonic muttered, snatching a chili dog. He took a huge bite, and his eyes rolled back. “Mmmph! These are insane!” he moaned, chili smearing his muzzle. The flavors exploded: spicy, savory, with a hint of smoky sweetness. He grabbed another, then another, unable to stop.

“Mmph! chomp Gotta be gulp the best chili dogs slurp in Station Square!” he mumbled between bites.

Sonic’s trim belly began to bulge, pressing against his white gloves as he stuffed his face. Each dog stretched his stomach a little more, his middle rounding out, quills splaying as he leaned back against the stall.

“Oh man, so hic good!” he groaned, licking his lips. The pile dwindled, but Sonic kept going, lost in a chili-fueled frenzy. His belly swelled, taut and heavy, jiggling slightly with each eager gulp.

“Mmmmph, more~ J-just chomp one more” he chuckled, patting his bloated gut. For once, the world’s fastest hedgehog wasn’t running…just eating, blissfully unaware of the trap he’d stumbled into.

*** *** ***

Sonic leaned back against the rickety counter of the “Chili Chompers” stall, his gloved hands cradling a belly so bloated it looked like he’d swallowed a beach ball. The last chili dog vanished down his throat, leaving a smear of sauce on his muzzle.

He let out a loud hiccup, his quills twitching as he patted his taut, rounded gut.

“Ugh hic h-how many was that? A dozen? Two dozen?” he groaned, his voice thick with overindulgence. The empty platter stared back at him, a testament to his gluttony. His middle gurgled, heavy and sluggish, yet a nagging pang twisted in his stomach.

“No way. I’m still hungry?” he muttered, eyes wide with disbelief. “I’ve been told I’ve got a big appetite, but that’s impossible!”

A sudden whirr and clank snapped him out of his food coma. The rusted mess of the abandoned stall shuddered, and a small, dented speaker popped out from a pile of scrap, sparking and crackling.

A flickering robotic sign lit up, its neon letters spelling out “GOTCHA!” in bold red.

Sonic’s quills bristled, his instincts kicking in despite his stuffed state. “What the?!” he started, but a familiar, booming laugh cut him off, echoing from the speaker.

“Mwa ha ha ha ha ha! Oh Sonic, you predictable little glutton!” Dr. Eggman’s voice dripped with smug satisfaction. Sonic could practically hear the villain twirling his outrageous moustache. “You’ve fallen right into my most ingenious trap yet! Using your insatiable appetite against you was truly stroke of genius from my unparalleled 300 IQ!”

Sonic staggered to his feet, his swollen belly wobbling as he glared at the speaker. 

“Urf! You egg-headed creep! What’s this hic all about?” he demanded, though another hiccup undermined his bravado. His legs felt like jelly, weighed down by the feast he’d just demolished.

Eggman’s cackle crackled through the static. “Oh, you poor, spiky simpleton! Those chili dogs weren’t just delicious! They were laced with my patented Super Appetite Stimulant! Tailored specifically for your pesky, super-fast metabolism!” He paused for dramatic effect, and Sonic could practically see the scientist’s arms flailing in glee.

“Right now, it’s kicking your hunger into overdrive! You’ll eat and eat until you explode from sheer gluttony! And if you try to run? HA! Your metabolism will convert every bite into pure, blubbery fat, weighing you down like a lead balloon! Either way, Sonic, you’re FINISHED!”

Sonic’s jaw dropped, his gloved hand instinctively clutching his gurgling belly.

“You…you what?!” he sputtered, feeling another sharp pang of hunger claw at his insides. It was impossible! He’d just scarfed down enough chili dogs to feed a family, yet his mouth watered, craving more. “You’re bluffin’, Eggman! I’m Sonic the Hedgehog! No way I can’t just run this meal off!” he snapped, though his confidence wavered as his stomach growled louder, demanding food. “It wouldn’t be the first time I’ve bounced back from a stuffing, fast as ever!”

“Oh, I’m not bluffing, you blue buffoon!” Eggman sneered. “My stimulant’s already working! Look at you, waddling like a stuffed turkey! Keep eating, and you’ll be too fat to move. Try running, and you’ll balloon up so fast you’ll be rolling instead of dashing! Either way, I’ve finally beaten you, Sonic! The world is MINE!” His laughter grew manic, the speaker buzzing with distortion.

Sonic clenched his fists, his bloated gut jiggling with the effort.

“You think a few extra HUUUOOORP mph, chili dogs are gonna stop me? I’ve taken down your robots on a f-fuller stomach than this!” he declared, but another hiccup and a fresh wave of hunger made him wince.

He glanced at the empty platter, then back at the alley, his mind racing.

“Gotta find a way outta this,” he muttered, his usual cocky grin faltering. His belly rumbled again, louder, more insistent, as Eggman’s laughter faded into static.

Sonic ran, picking up speed as he escaped the dingy back alley.

But as he took step after step, his heavy middle swayed, slowing him down.

The hunger gnawed harder, and the abandoned stall’s shadows seemed to loom larger. Eggman’s trap was tightening, and Sonic’s appetite was becoming his worst enemy.

The narrow passageways of Station Square twisted around him, but something was wrong! His lightning speed felt sluggish, his limbs heavy. His quills splayed as he felt his body soften, like dough rising in an oven.

“No way huff it’s happening already!” he panted, glancing down.

His once-trim middle was swelling, his white gloves straining against chubby fingers. His thighs thickened, rubbing together, and his iconic red sneakers looked comically small beneath his ballooning frame.

By the time he burst onto Station Square’s bustling main street, Sonic was a wobbling, 300-pound mass of blue blubber!

His belly jiggled like a water balloon, his chest puffed out into soft moobs, and his cheeks puffed up, making his cocky grin look more like a pout.

“Urgh! hic This is nuts!” he groaned, stumbling to a halt. Each step sent ripples through his newfound girth, his quills barely poking out from rolls of fat. He tried a spin dash, but instead of rocketing forward, he rolled clumsily, landing with a thud that shook the sidewalk. 

“Rrrrgh! Eggman, you dirty cheat! This is way below the belt! You’ve made me almost as fat as you are!” he whined, clutching his gurgling stomach. The hunger hit again, a ravenous claw twisting his insides. “How am I starving after all those chili dogs?!”

He struggled to his feet, his heavy frame waddling as he tried to focus.

“Gotta get to Tails’ workshop. He’ll know a way to fix this. Hmmm…Mystic Ruins ain’t that far,” he muttered, picturing his buddy’s gadgets fixing this mess. “If I haul tail, I can make it in…uh, ten minutes? Maybe fifteen?” His confidence faltered as his wobbly legs protested, his breath short.

But before he could plot his next move, a metallic clank echoed through the square.

Sonic’s quills prickled. “Oh, come on, what now?!” he exclaimed breathlessly.

The streets erupted with chaos. Eggman’s Badnik robots swarmed in, their clunky forms buzzing and whirring as they set up dozens of food stalls in a flash!

Brightly colored stands popped up like mushrooms, each one pumping out mouthwatering aromas. Chili dogs sizzled on grills, their spicy scent curling into Sonic’s nose. Pizzas spun in robotic hands, loaded with gooey cheese. Burgers dripped with grease, fries crackled in deep fryers, and ice cream churned in pastel swirls.

The air was thick with temptation; greasy, sugary, irresistible. Sonic’s stomach roared, loud enough to drown out the city’s noise.

“No, no, no! Not now!” he moaned, clutching his belly as it growled. “I really can’t be eating more at a time like this!”

He staggered forward, trying to push through the crowd, but the smells were everywhere. A Moto Bug rolled up, its mechanical arms offering a tray of chili-slathered hot dogs. A Buzz Bomber hovered overhead, dropping a basket of crispy fries right in his path.

“Get away from me!” Sonic snapped, swatting at the robots, but his flabby arms barely made a dent. His eyes locked on a triple-decker cheeseburger, its bun glistening with sesame seeds.

His mouth watered, his resolve crumbling.

“This…this ain’t fair!” he whined, his voice high-pitched with desperation. “Eggman’s playin’ dirty!”

He tried to waddle faster, but his massive hips swayed, knocking over a stack of pizza boxes. A robotic vendor beeped, “Free samples! Eat up, hedgehog!”

Sonic’s hunger clawed harder, his bloated belly begging for more.

“I gotta get to Tails… gotta resist…” he panted, but the tantalizing scents wrapped around him like a trap. The Badniks closed in, their stalls forming a gauntlet of fattening delights. Sonic’s chubby cheeks flushed as he realized he was surrounded, his appetite waging war with his willpower.

“Eggman, you’re gonna pay for this!” he growled, but his rumbling stomach had other plans.

*** *** ***

Sonic’s wobbling bulk swayed as he staggered from one Badnik-run food stall to the next, his hunger overriding every ounce of his heroic resolve. His belly, already a bulging blue orb, gurgled furiously, demanding more.

“Gotta…resist…” he mumbled, but a tray of sizzling chili dogs beckoned, their spicy aroma curling into his nose.

He snatched one, then two, cramming them into his mouth. Chili dripped down his chubby cheeks, staining his white gloves. “Mmmph! So…good!” he moaned, his eyes half-lidded in gluttonous bliss. His stomach swelled tighter, pushing against his quills, now barely visible under rolls of flab.

He lurched to the next stall, where a Buzz Bomber hovered with a stack of greasy pizzas. Sonic grabbed a slice, cheese stretching as he shoved it in, followed by another.

“Mmmmmnnn~ Can’t…stop…want more!” he panted, grabbing a triple-decker cheeseburger from a Moto Bug’s claw. He tore into it, ketchup and mayo smearing his muzzle. Fries followed, stuffed in handfuls, washed down with a gallon-sized soda that fizzed and bubbled in his gut.

A robotic vendor offered a thick milkshake; Sonic slurped it down, brain freeze be damned, before scooping up a tub of ice cream. Chocolate fudge swirled over his tongue as he shoveled it in, his belly ballooning further, gurgling like a volcano ready to erupt.

Each time Sonic tried to dash between stalls, his body betrayed him. Eggman’s appetite stimulant worked overtime, and his super-fast metabolism turned every calorie into fat. His thighs thickened, rubbing together until they chafed. His arms jiggled, his moobs bounced, and his belly swayed like a pendulum.

By the third stall, he hit 400 pounds, his sneakers squeaking under the strain. By the fifth, he was a staggering 500 pounds, a blue mountain of blubber waddling through Station Square.

“G-getting too UUURP h-heavy! Too fat!” he whined, his voice muffled by a mouthful of fries. “I f-feel slurp f-funny…eating like this feels…too good to resist!”

Suddenly, speakers popped up from every stall, blaring a jaunty tune mixed with Dr. Eggman’s cackling voice.

“Citizens of Station Square!” he boomed. “Come, witness your precious hedgehog hero, Sonic, glutting himself into oblivion! Look at him! Fat, slobby, and pathetic! Point and laugh at the blue blimp!” The music looped, mocking and triumphant.

Sonic’s ears twitched, his face flushing as townspeople gathered. Kids giggled, adults whispered, and cameras flashed.

“Is that Sonic?” one gasped.

“He’s huge!” another snickered.

“What a pig!” a teen shouted, pointing.

Sonic’s chubby cheeks burned, his bloated body quivering as he tried to glare through the crowd. “Laugh all ya want!” he slurred, shoving another burger in his mouth. “I’m still BUUOORP Sonic the Hedgehog!”

But his bravado crumbled as his belly growled louder, urging him to the next stall. Ice cream dripped down his chin, mixing with pizza grease. His massive frame wobbled, barely able to waddle now, each step sending ripples through his flab.

The crowd’s laughter grew, their whispers cutting deep:

“He’s so fat!”

“Can he even run anymore?”

“What a slob!”

“He’s really putting the ‘hog’ in hedgehog!”

“Heh, more like Sonic the Huge Blob!”

Sonic’s heart sank, but his hunger roared stronger. He grabbed a tray of chili fries, unable to stop, his body swelling with every bite.

Eggman’s voice echoed again: “Keep eating, Sonic! You’re my masterpiece of gluttony!”

The hero’s eyes darted to the horizon, Tails’ workshop a distant hope. But with Badniks boxing him in and food stalls tempting him at every turn, Sonic was trapped! His appetite his greatest foe, and the crowd’s laughter his humiliating soundtrack.

And worst of all…was how much Sonic was strangely enjoying it!

The Station Square crowd’s whispers and gasps—pointing at his ballooning belly, his sagging moobs, his wobbling thighs—stung his pride, but something strange was happening. 

The shame, mixed with the rich, greasy flavors coating his tongue, sent a confusing thrill through him. His cheeks burned, not just from embarrassment but from a growing, guilty pleasure.

“Ugh… hic… why’s this feelin’ so… good?” he grunted, his voice muffled by a mouthful of pizza.

Between his now blubbery legs, he felt his hedgehog cock make itself known, stiffening and growing erect, cushioned by his fat blue fupa. Every movement he made caused his newfound fat to weigh down upon it, providing Sonic with the most pleasurable pillow imaginable!

He blushed, then snatched another chili dog, sauce dripping down his chin, and shoved it in, moaning as the spicy heat hit his taste buds. His belly gurgled, swelling tighter, pushing out further until it dominated his frame. Each bite made him heavier, softer, his quills nearly buried under rolls of blue blubber.

“Gotta…stop…” he panted, but his hands grabbed a milkshake, slurping it down in greedy gulps. The cold sweetness made him shiver, his massive gut jiggling as he leaned against a stall, feeling it weigh upon his cock.

With just the slightest jiggle, it bounced up and down onto his erection, smothering him in pleasurable softness.

“He’s huge!”

“What happened to Sonic?”

“Woah, is he getting…turned on?!”

The attention only deepened the strange rush coursing through him. He wished he could duck into an alley, away from prying eyes, where he could indulge in peace. Eating felt too good, and shamefully…getting fatter was starting to feel good too.

He felt like he was moments away from blowing his load, right here in the street!

A bright light blinded him as a Station Square news crew shoved through the crowd, a camera trained on his bloated form.

A reporter, microphone in hand, shouted, “Sonic the Hedgehog, once the world’s fastest hero, now a gluttonous spectacle! Look at him, folks—making a pig of himself!” The camera zoomed in, capturing his sauce-stained muzzle, his wobbling belly, and the fries spilling from his gloves.

“Sonic, stop before you’re too fat to move! You’ll explode!” the reporter pleaded, her voice a mix of concern and sensationalism. “And from the looks of it, you might explode in other ways! Our station isn’t rated for that, Sonic! Think of the children!”

The crowd gasped, some laughing, others whispering in shock:

“He’s a big horny blimp!”

“Is that really Sonic? I didn’t know he was…so big!”

“Mommy! Watching Sonic get fatter is making me feel funny!”

“Look away, little Timmy! Don’t you look at the obese hedgehog! Don’t let him awaken anything in you! No child of mine is gonna grow up to be a furry!”

Sonic’s ears twitched, his chubby cheeks flushing redder.

“I-I ain’t a pig!” he slurred, but his hands betrayed him, grabbing a triple cheeseburger and cramming it in. The greasy, savory explosion on his tongue drowned out the humiliation.

His body ballooned further, hitting 600 pounds, his spherical form barely recognizable as the sleek hedgehog he once was. His fat legs, thick as tree trunks, were slowly merging into a massive, doughy monobutt that swallowed his red sneakers. His arms jiggled, barely able to reach the next tray of fries.

“This slurp aint wheeze f-fair! gulp” he whined, yet his moans carried a shameful thrill, his body trembling with each fattening bite.

Eggman’s voice blared from the stall speakers, gleeful and mocking: “Keep eating, Sonic! You’re my greatest victory! Thanks to my limitless genius, you’re now a waddling, gluttonous disaster for the whole city to see!”

The crowd’s laughter swelled, but Sonic couldn’t stop.

He grabbed a tub of ice cream, scooping it with his bare hands, the cold sweetness mixing with his guilt. His belly surged outward, taut and heavy, his monobutt spreading across the pavement.

“Gotta mmrph g-get to gulp Tails…” he gasped, but the thought of the Mystic Ruins felt distant, buried under his ravenous hunger.

The news crew kept filming, the crowd kept jeering, and Sonic—now a blue sphere of blubbery fat—kept eating, trapped in a cycle of shame, hunger, and pleasure.

*** *** ***

Sonic, now a 600 pound sphere of blue blubber, wobbled amidst the food stalls, his monobutt spreading across the pavement, his sauce-smeared face buried in a tub of ice cream. The crowd’s laughter and the news crew’s cameras burned his pride, but his hunger kept him glued to the feast.

“Ugh… hic g-gotta…s-stop…” he moaned, his voice thick with shame and indulgence.

Suddenly, a familiar WHIIIIRRRRR cut through the chaos!

The Tornado’s red wings roared overhead, Tails’ biplane swooping down like a guardian angel.

“Sonic!” Tails shouted from the cockpit, his twin tails spinning as he maneuvered. A massive claw crane, rigged to the plane’s underbelly, descended with a CLANK.

Before Sonic could react, the claw snatched him up, hoisting his enormous, jiggling frame into the air. His bloated belly swayed, fries and chili sauce raining down as the crowd gasped.

“Hang on, buddy!” Tails called, banking the plane upward.

Sonic dangled helplessly, his spherical body swaying in the crane’s grip.

“T-Tails?!” he belched, his voice a humiliated groan. His quills, barely visible under rolls of flab, twitched as he tried to muster his usual cocky grin. “I’m…BUUUOOOORRRP f-fine, just…HUUOOORRPPH ugh, g-get me outta here!” he moaned, his massive gut gurgling loudly.

The news crew filmed frantically, the crowd pointing as Station Square shrank below.

“Just hang on, Sonic!” Tails asked, glancing back with wide, worried eyes. “We saw what was happening on the news and hurried to get to you. I’m taking you to the lab. Knuckles, Amy, and everyone else is waiting! We’ll fix this!”

Sonic could only manage another loud belch, his chubby cheeks burning red.

His once-sleek frame was now a wobbling mass, his monobutt and swollen belly making him look more like a parade blimp than a hero.

“Th-thanks…” he muttered, but the humiliation stung worse than any Badnik.

As the Tornado soared toward the Mystic Ruins, Sonic’s moans mixed with the wind, his appetite-fueled nightmare far from over.
