#stiles stilinski | ultram0th (2024)

“Stiles!? Stiles, where the hell are you?” Derek roared out as he scanned the large crowd for his boyfriend.

The werewolf sighed as he pinched the bridge of his nose in irritation. Stiles had won some online comic book contest, giving him a trip for two to Metropolis for the Annual Superman Parade. At first, Derek hadn’t wanted to spend his weekend at some overcrowded city where a bunch of nerds would be talking nonstop about comics; however, when he’d seen the glee in Stiles’s eyes, Derek had immediately melted and had agreed to go.

At his boyfriend’s behest, Derek wore a tight Superman t-shirt that he’d bought at Wal-Mart on the clearance rack. Just right before the parade was due to start, Stiles had gotten distracted and ran off towards a pretzel stand, disappearing into the crowd.

For the past twenty minutes, Derek was shoving his way through the crowd, looking for his boyfriend. “Stiles!” he yelled out again. “Damn it, I swear I’m gonna put a bell on that guy…”

In his hast to find Stiles, Derek angrily stomped past a bald man dressed in a suit that seemed to be too nice for just attending a parade. The man looked over at the frantic werewolf, a smirk formed on his face.

“Looking for someone?” he asked Derek, putting on a nice tone. “Missing child?”

Derek froze, but then huffed in agitation. “Missing boyfriend,” he corrected begrudgingly. “He went off the pretzel stand and got lost in the crowd. He’s wearing a superhero costume…” His voice trailed off when he realized that his description wouldn’t help due to hundreds of other people on the street dressed up as comic book characters.

The bald man just nodded his head. “Yeah, it’d be rather difficult to locate a singular nerd out of a thousand,” he hummed. “I know a way you can spot him easier, though.”

Normally, Derek would prefer to work solo, yet he wasn’t too keen on having his boyfriend lost in an unfamiliar city. Hence, he nodded. “Sure,” he grunted. “That’d be great. Thank you.”

The bald man’s smile grew. “Follow me, please,” he said, turning around and leading Derek through the crowd. The two of them walked into a nearby, unmarked building and headed directly towards the elevator which had to be operated with a key that the bald man had.

The elevator led all the way to the rooftop of the building. Initially, Derek thought that this was a great idea since he would be able to look down over the side and scan the crowd for Stiles. However, when he stepped out of the elevator, he spotted an odd looking machine that resembled an oversized shop vacuum, complete with a large hose. Blinking lights decorated the front, and they flickered with a neon green aura to them.

“Um,” Derek mumbled, shrugging it away, “thanks again for your help, Mister, um…”

“Luthor,” the bald man introduced himself. “Dr. Lex Luthor.”

For a brief moment, Derek could’ve sworn that he’d heard that name from somewhere before, like from one of the movies that he and Stiles had watched together (or more apt, a movie that Stiles watched while Derek felt him up). The alpha shook his head, figuring that it must’ve just been a common name as he started to walk over towards the edge of the rooftop, his lupine eyes searching for his hyperactive boyfriend.

In the background, he could pick up the sounds of Dr. Luthor moving around and messing with something. He ignored it though, perking up once he saw a familiar figure hovering by one of the numerous shop stands.

“Stiles!” Derek called out. “Stay there and— mmpphh!”

Derek’s voice was cut off when Lex Luthor shoved the large hose into his mouth, a clicking sound ringing out as a strap in the back locked it in place. Derek immediately shoved the older man away from him, grabbing onto the hose with both hands and trying to pull it off his face. It was secured tightly in place, refusing to budge an inch. He could still breathe just fine, but his heart began to race in his chest as he wondered what the hell was going on.

“Grrr!” Derek growled, his words still obstructed, as he threateningly leaned towards Lex.

The bald guy just smirked. “Don’t try to fight it, Mr. Hale,” he said as he coyly walked back over to the large machine that the other end of the hose was attached to.

Derek co*cked his eyebrow, wondering how this random stranger knew his name.

Dr. Luthor just snickered as he began to punch a few of the green buttons. “You honestly think your little boyfriend won that contest to come to Metropolis based on his talent alone?” he balked. “I mean, the guy submitted a handmade comic entitled Wolfman, and he not-so-subtly designed the hero after you.”

Derek’s broad shoulders fell, knowing that that did sound like something Stiles would do. Still, wanting to defend his boyfriend’s honor, Derek growled again and kept trying to tear the hose away from his mouth.

“So I had to rig the contest to make sure that the two of you would come to Metropolis so that I could test out my latest experiment on you!” Dr. Luthor explained, his voice quaking with excitement as his fingers furiously kept pressing the flickering buttons, a whirring beginning to sound out from the machine. “After all, if it works on an alpha werewolf, then it’s sure to work on Superman!”

Derek rolled his eyes at the insane-sounding bald man. Superman wasn’t real, he told himself; therefore, he was being attacked by some crazed comic book fan. Of course this would happen to him…

The whirring from the machine grew in intensity, growing louder and faster. It turned into a loud hum, mimicking the sound of a generator.

“Hold on, Derek,” Dr. Luthor laughed. “You might feel a little… pressure.” He flipped a switch.

Derek winced as he felt a gust of air blow through the tube, coming out of the machine and going directly into his mouth, making his cheeks puff up from the action.

“Hmm?” Derek couldn’t help but ask in surprise. A number of different scenarios had ran through his head regarding what the machine would do, but just blowing air wasn’t one of them.

Dr. Luthor’s eyes began to light up with zeal. “It’s a success!” he practically cheered, going so far as to ball up his fists with joy. “Look!”

Derek scrunched up his brow in confusion before paling once a tingle rippled across his body, and a horrifying sensation began to creep up.

Steadily, Derek could feel his Superman shirt start become tighter as the air continued to blow into his mouth. In a panic, Derek looked down at himself, his eyes nearing bulging out of his skull as he saw a lump at his midsection where rigid abs should’ve been. The humming from the machine picked up, and Derek’s stomach pushed outwards, growing larger and much more rounder.

Derek frantically pressed his hands against his growing gut, as if he could stop its growth. However, not only did he feel it continue to get bigger, the werewolf was startled by the squeaky noises of rubber balloons sounding out. Worse was that the more he moved, the more the squeaky sounds rang out, as if Derek’s skin were now rubber, expanding as he grew larger and larger.

The growth wasn’t solely focused on his belly, Derek was horrified to discover. His pecs began to inflate too, rounding out as they ballooned out in front of him. With two audible boinks, his nipples poked out, pressing tightly against his straining t-shirt. His pant’s button ricocheted off as his butt began to bubble out, growing large and bulbous as it blew up with air from the mysterious machine.

Derek tried with much more gusto to tear the hose away from his face, but then his arms began to inflate. So much air was pumped into them that they grew inflexible, and Derek couldn’t maintain his grip on the hose. His arms were forced to hang out at his sides, akimbo. He furrowed his brow intently as he tried to move them, but all he could do was barely wiggly his hands as his entire body grew.

All of the muscles in Derek’s enlarged body looked overly inflated and out of proportion. They were ridiculously huge and round, making movement near impossible. Derek’s arms were stuck at his sides, and his thighs had grown so wide that they constantly pressed against one another, forcing him to stand with a wide stance. The whole time he struggled to move, the squeaking noises of balloons echoed out from his expanding form.

The growth even traveled south to Derek’s co*ck, pumping it up to incredible proportions. It lengthened out to almost a foot long, and thickened up to the girth of his normal-sized forearms. The amount of air in it forced it to stand straight out in front of the growing Derek, his balls blowing up to the size of softballs.

Dr. Luthor glanced at his expensive-looking watch before turning a dial on the machine. “As much as watching you turn into a helpless blimp, Derek,” he teased, “I’m on a really tight time crunch. Let’s hurry this up, shall we?”

The machine roared with power as it forced more air down the powerless werewolf’s throat.

Derek felt his muscular physique begin to falter as his body started to round out even more, taking on a more spherical appearance. His traps and pecs inflated to such enormous proportions that they ballooned up and swallowed Derek’s neck, making his head look hilariously tiny atop a round body. His torso inflated so much that it began to gradually grow over his limbs. His arms and legs seemingly sucked into his bulbous midsection, leaving the werewolf’s hands to flap around uselessly as he still futilely tried to tear the hose away from him. His stubby legs threw him off balance, and Derek felt himself fall onto his back. He was so full of air that he actually hovered in the air, floating weightlessly as he ballooned up. He could barely move, he was so big. And even if he could roll around, he was too light to even touch the ground, leaving the alpha one-hundred percent at the mercy of the mad scientist.

“Aaand, that should be good!” Dr. Luthor said as he shut off the machine.

The air stopped, and for a brief second, Derek was relieved that he wasn’t growing anymore. However, that relief was short-lived when he looked downward, his view of his body blocked by his hyperbolically inflated pecs that were so huge and round. Based on the large shadow he created, Derek estimated that he had to have grown to the size of one of the parade floats he’d seen on TV. His Superman t-shirt miraculously remained intact, making Derek look like an overinflated Superman.

Dr. Luthor walked forward and quickly tied ropes around Derek’s hands and feet, holding onto them so that the werewolf wouldn’t float away. He yanked one the ropes, causing Derek’s balloon-like body to jerk downwards enough so that the hose could be unlocked and removed from his face.

“Well, Mr. Hale, what do you think of your new body?” Dr. Luthor mocked, a sinister smirk on his co*cky face. “If I may toot my horn, I’d say that I just created the biggest Superman parade float that Metropolis has ever seen!”

“You son of a bitch! You better turn me back!” Derek roared, blushing when he heard the squeaky sound of his voice. The air that had been pumped into him must’ve had large amounts of helium, making Derek sound like a chipmunk, made all the more ridiculous with his giant body.

“‘Turn you back’?” Dr. Luthor asked, looking genuinely confused before shrugging. “I’m not sure there is any going back, Mr. Hale. I mean, after all, you’ve stretched out way beyond any normal proportions so I really don’t think you’ll just bounce back, per se. Perhaps we could look into bulking you up so you can at least stay grounded with your new girth.”

Derek was stunned at what he heard. He was so caught up in the horrible news that he was potentially looking at a future as a giant blimp, that he’d barely noticed when Dr. Luthor tossed the long ropes down the edge of the building towards where some of his cronies were waiting. His crew grabbed the ropes and hurriedly walked into the parade, continuing down the street at the same pace as the rest of the performers.

“W-wait!” Derek cried, humiliated at the thought of his inflated form being paraded throughout the bustling city for all to see.

His enormous body was pulled out into the parade among the other floats, of which his size was in par with. Immediately, the werewolf’s sharp ears could pick up the gasps from the crowd as they looked up at his balloon-like body.

“Whoa!” a man shouted as he pointed upward .”Check out that over-inflated Superman! His belly is massive!”

“That’s a bit too big for Superman. That has to be some kinda fetish work, right?”

“Look at the size of that bubble butt!”

“He looks huge!”

The crowd erupted into thunderous laughter, many people pointing at Derek’s inflated body and making comments about the obscene size of his pecs, belly, or ass.

Derek’s face was cherry red as he blushed at the comments about his inflated body. It was hard to turn his head with almost no neck, but he could see his huge form in the reflection of the glass lining a skyscraper.

Derek groaned at how large and round he looked. His gut was so spherical and enormous that it was definitely the center of his growth. Not to be outdone, his ass cheeks had blown up as well, protruding out into the air as he floated through the city, all of the parade-goers gawking at his round form. His head looked hilariously tiny as it sat in the middle of his torso, almost sinking into his inflated pecs which were capped with nubby, protruding nipples. The Superman icon on his t-shirt had stretched out over his larger chest, making him feel like some warped superhero as he helplessly floated through the city.

Derek tried desperately to grab onto the ropes to pull himself back down to the ground, but he was so rotund that all he could do was helpless wriggle his fingers and kick his feet. Dr. Luthor’s crew kept laughing wildly as they carried Derek throughout Metropolis, going so far as to even bring attention to his inflated form.

“Hey! Check out the massive new Superman float we got. A bit overfilled, isn’t it?” one of them giggled.

Derek’s face was crimson now as he was shown off.

“Derek?! What happened to you?!” he heard Stiles cry out among the crowd.

The werewolf slightly perked up and tried to look around for his boyfriend, but his pecs were so large that he couldn’t see anything past them. “Some freak turned me into a damn balloon!” he squeaked, wincing again at his silly voice.

Derek could hear Stiles’s feet hurry over towards him. The sounds of grunting echoed as a scuffle broke out, and Derek could feel himself being carried away from the parade at a little faster pace.

“I gotcha Der!” he heard Stiles say. “You’re actually surprisingly light…”

Derek couldn’t see thank to his inflated form, but Stiles had managed to snatch the ropes away from Lex Luthor’s cronies. He ran down the other block, carrying his parade float boyfriend away from the crowd so that they could figure out a way to fix him.

For a second, Derek breathed out a sigh of relief before something off in the distance caught his eye. “H-hey,” he squeaked, “something’s coming this way. A plane?”

Stiles looked up into the air, gasping loudly. “Holy sh*t, Der!” he exclaimed excitedly. “It’s Superman!”

“Of course it is…”

Sure enough, the flying object approached at lightening speed, stopping midair right in front of Derek’s inflated form. Despite how impossible it sounded (and crazier things had happened that day, clearly), Superman floated right in front of the werewolf. He looked just as he did on TV, yet Stiles swore that Superman and Derek shared a few facial features.

“Whoa there, Big Guy,” Superman whistled as he looked over Derek’s parade float body, “it’s looks like Lex Luthor used you as a guinea pig for one of his diabolical experiments.”

A twinge of anger sparked inside of Derek, knowing that it should’ve been Superman who’d been turned into a freakshow, not him. “Yeah…” was all that he could say in his helium-esque voice.

“Superman!” Stiles gushed down below on the ground. “I’m your biggest fan! I’ve read all of your comics and seen all of your movies! I have so many questions to ask you if you have any time at all!”

Superman just smiled warmly down at the talkative human. “Sure thing, Citizen,” he said in his deep voice that oozed manliness, and Derek couldn’t help but feel a little jealous. “But first, I think we should figure out what to do with your friend here.”

“Boyfriend,” Derek squeaked.

“Can you turn him back, Superman?” Stiles asked, his knuckles turning white from onto the ropes tightly.

Superman rubbed at his square, chiseled jaw in thought before crossing his big, but manageable, arms over his chest. “I think I have a better idea,” he admitted. “Something that could benefit everyone involved.”

Derek gulped loudly.

[Two Weeks Later]

“Everything’s all set!” Superman, disguised as Clark Kent, announced, beaming ear to ear.

“Are you ready, Der?” Stiles asked.

“Um, I guess so,” Derek stammered, his voice still sounding like helium.

“Well, the Halloween Parade’s starting, so let’s go!” Clark said as he pulled on the ropes and began walking among the crowd.

Again, Derek was paraded throughout Metropolis, being the largest parade float on the block. This time, in preparation for the Halloween Parade, Superman had painted him head-to-toe orange, making him look like a massive pumpkin. Derek still blushed as all eyes were on his inflated form, but the inflated werewolf forced a nervous smile onto his face as he tried his best to wave an inflexible arm.

Superman’s great idea, since he had no idea how to turn Derek back to normal, was to just use the werewolf as Metropolis’s biggest parade float, opting to dressing him up to fit whatever parade it was supposed to be. For the Thanksgiving Parade next month, Superman had plans to dress up the inflated Derek as a large turkey.

Of course, it wasn’t Derek’s first choice. However, he couldn’t deny that a part of him liked to see Stiles happy attending parades on the regular, so he tried his best to swallow down his horror over his new life as an overinflated parade float, and tried his best to give in.

Derek smiled and waved to the crowd as best as he could, still blushing slightly as onlookers commented on how massive he looked.
