Day 29: Butt Growth

Derek collapsed back onto the bed, next to a sweaty Stiles. The both of them panted from their latest romp, Stiles waiting for the sensation in his legs to return after Derek totally drilled into him.

Th alpha werewolf’s libido seemed to be in overdrive, given the proximity of the full moon. Stiles was overjoyed about this fact, eagerly bending over to help his boyfriend release some of his sexual tension. That being said, after being the one to bottom over and over, Stiles was interested in a little change of pace.

“Hey, Der?” he panted, struggling to catch his breath.

“Hmm?” Derek hummed, already feeling himself grow hard at the scent of musk and pure sex permeating their bedroom. He gradually scooted closer to his boyfriend on the mattress, wrapping his large arms around his slender form, rutting his hardening cock against his perky butt.

“Wanna switch positions?” Stiles asked.

Derek paused his rutting and cocked his eyebrow at his boyfriend. “Huh?”

Stiles sat up and shifted himself closer to Derek. “Like, how about I be the top this time?” he suggested, trying to seductively wriggle his brow at the werewolf who only scoffed in response.

“Babe,” Derek snorted, “I’m the alpha, so I’m the top. There’s no way I’m gonna bottom… ever.” Sure Derek loved Stiles and he was well aware that he was in a homosexual relationship (clearly), but he couldn’t help but feel like bottoming was something that only the “girl” in the man x man relationship did. Being an alpha and being the tough guy that he was, Derek wouldn’t be caught dead being the bottom.

Stiles frowned. “A simple ‘No’ would’ve been fine…” he muttered before perking up. “Well, maybe you just need some convincing.” He snapped his fingers, grinning knowingly.

Before Derek could ask what was up, the alpha felt an odd tightness centering at his glutes. It felt as if he’d just finished a rigorous leg day at the gym, feeling his backside burn and ache as if he’d just completed some serious squats.

Derek’s lower back felt as if it were being lifted upwards off the bed, and the werewolf flipped over onto his stomach and looked over his broad shoulder, gasping loudly.

The toned butt that was perfectly proportional with the rest of Derek’s impressive muscles was magically bubbling out from his back. His butt grew in size, pushing out and rounding to form a fuckable bubblebutt that was too large for his body.

“Wh-what’s happening?!” Derek panicked, pressing both of his hands on his growing ass, paling as they felt small compared to his massive cheeks. He could feel his hands being pushed further away as his butt continued to grow in waves, thrusting itself away from his lower back, jiggling wildly with every movement.

Stiles couldn’t hide how turned on he was by watching Derek’s butt grow bigger. “Don’t worry, Der,” he said, loving how out of proportion his boyfriend’s butt looked, “if I did the spell right, it’ll wear off in a few hours.”

“Hours?” Derek repeated, flinching when the tightness finally subsided.

Bolting off the bed, the first thing Derek noticed was that his thighs had packed on a little more meat to account for the extra weight at his bottom. When he took an awkward step forward, Derek blushed as he felt his inflated cheeks bouncing and rolling over each other. He got to the floor length mirror in the bedroom, wincing as he looked at his warped reflection. The rest of his body remained unchanged, making Derek’s enlarged bubblebutt all the more ridiculous. It had to be at least three times its normal size, and it created a near perfect shelf as it jutted out from his lower back. Derek gave his hips a tentative shake, his heart racing as he watched his cheeks ripple and shake from the slightest movement. His butt was so large and out of place that his waist seemed to pinch inwards before ballooning out into his new bubble.

Derek looked away from the mirror for a split second to shoot a pleading look over at Stiles— Stiles was rock hard, and the second Derek’s eyes landed on his cock, he felt something inside of him flip.

Used to feeling a surge of lust and then having his cock rocket to life, Derek still felt himself get hard, but there was also an intense desire that he felt deep within his inflated butt. He didn’t know exactly what it was, but Derek felt desperately empty, and he couldn’t help but clench his enlarged cheeks with want.

His meaty pecs rising and falling as he breathed heavily, Derek couldn’t help but run towards the bed, ignoring the bouncing weight at his back. He threw himself onto the bed and perched up on all fours, shoving his inflated ass towards Stiles.

“Pl-please?” Derek begged, wiggling his hips teasingly and making his butt jiggle.

Stiles couldn’t help but smirk. “‘Please’ what?” he asked, crossing his arms over his chest.

The need was overwhelming, like there was deep, intense itch inside of him that needed satisfying. Derek gritted his teeth and pushed his giant butt closer to Stiles, grabbing his cheeks and pulling them apart to flash his tight hole. “Please fuck me!” he begged.

Stiles crawled forward and grabbed a hold of Derek’s waist, right at the crest of his overblown mounds. As he worked himself inside of Derek, he loved the way Derek tensed up.

“Oooohhhh fuuuuck,” Derek moaned as he pressed his forehead against the hard mattress as he was stuffed full. Automatically, Derek started to buck and roll his hips in tune to Stiles’s thrusts. 

As Derek was heatedly fucked, he couldn’t help but marvel at how intense the pleasure that surged throughout his altered body was. His cheeks bounced and rippled, adding to his orgasmic bliss. He could still see himself in the bedroom mirror, noting that he looked ridiculous with his large muscles and even larger ass, getting fucked silly by his much smaller boyfriend. His jaw was slack as he moaned like a slut, and his useless, untouched cock bobbed between his thighs, drooling precum.

Despite his previous disdain with bottoming, Derek felt himself craving the sensation of being filled with his boyfriend’s cock. His enormous ass wasn’t something to be embarrassed by, but it was a gateway to the ultimate pleasure.

By the time Stiles tensed up and came, filling Derek up with his load, Derek had already came about twice. He unconsciously flexed his cheeks as his boyfriend came, desperately milking him to get more of that sensation of being full.

“Holy fuck,” Derek panted, his chest slick with sweat. “We have to do that again!”

[2 Weeks Later]

True to Stiles’s word, the spell had worn off after a few hours, and Derek’s butt had deflated back to its normal size. Still, the werewolf loved to top his human boyfriend, and would mount him on the daily. However, there were now times when Derek would playfully walk up to his boyfriend and press his toned butt against him.

“I think it could use some more size, what do you think?” he’d coyly ask, biting down on his lower lip in anticipation as Stiles would snap his fingers, and Derek would feel his pants grow tighter…

Day 26: Twink

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19 │ 20 │ 21 │ 22 │ 23 │ 24 │ 25 │ 26

Derek bumped into some small, tiny guy. The little guy wore comically oversized clothes as he ran off, looking panicked and frightened. 

“Fuckin’ weirdo,” Derek snorted, readjusting his gym bag over his broad shoulder. 

The 6’3” alpha sauntered into the gym to workout. Normally, the muscled stud preferred to lift or perform bodyweight exercises at home where he wouldn’t have to deal with a lot of people. However, after renovating his house, he didn’t want to mess it up with his musk, so he’d opted to get a gym membership. After a few weeks of working out at one of the local gyms, Derek was surprised to discover that he actually liked to work out in public. There was something about being one of the bigger guys at the gyms that filled him with a sense of pride. Towering over the other men and easily out-muscling them only cemented his role as an alpha, and Derek could only smirk as he threw his weight around the gym.

After changing in the locker room, Derek strutted out onto the gym floor clad in only tight gym shorts that strained against his powerful thighs. His impressive chest muscles were on full display as he moved towards the weight pile. His chiseled, plump pecs illustrated sheer masculine power, and Derek frowned a bit when he realized that the gym was virtually empty.

“Guess the other guys just can’t keep up,” he hummed to himself, grabbing the heavier weights on the rack and performing bicep curls like it was second nature to him. His bowling ball-sized mounds flexed with power as he lifted, and Derek couldn’t help but admire his bulky form in the large mirror.

Derek was so caught up in working out that he barely noticed when another gym patron walked up to the weight pile, grabbing a weight that was a little heavier than Derek’s.

This other guy rivaled Derek’s size, both in height and musculature, much to the alpha’s annoyance. This other guy’s thick curly hair reached the same exact 6’3” height as did Derek; that fact bothering Derek for some inane reason. Plus, this other guy also worked out shirtless, showing off his pumped up muscles that exuded manly power. His chiseled pecs were just as rounded as Derek’s, and when he lifted his weight, his bicep bulged to the same exact size Derek’s had.

The other guy glanced towards Derek and nodded at the lighter weight in his grasp. “My girlfriend likes to use the smaller weights too,” he chuckled.

Derek bristled at the obvious attempt to make him look weaker than the unknown douchebag. He just clenched his jaw as he set the weight down, opting for an even larger one than the other guy’s. Gritting his teeth, he began to rack out several bicep curls.

The subtle way the other man’s eyes widened caused the alpha to smirk, loving how his bicep pumped up to an incredible size. The arm burned with lactate and he could vaguely make out the other guy muttering something under his breath, yet Derek was too focused on trying to look like the bigger man.

Derek’s muscles burned from his workout, the burning sensation seemingly spreading throughout the rest of his body from his arm. The immense weight in his hand steadily felt heavier by the second, Derek chalking it up to reaching muscle failure. He thought that it was odd that he’d reached it in under a minute since he could usually lift heavy amounts of weight for a substantiated amount of time.

Derek grunted as he attempted to perform one more rep, yet his arm started to shake and he ultimately dropped the weight, letting it clang loudly onto the floor. 

The guy chuckled again, and clapped Derek on the bare shoulder. “Don’t worry, Little Guy,” he teased, “there’s no shame in starting off with the smaller weights. We all gotta start somewhere, right?”

Derek swallowed down a growl and instead tried to glare threateningly at the other guy to get him to leave him alone… but he stopped when he stared directly at the dude’s chin. Earlier, Derek could’ve sworn that they’d stood eye to eye.

Derek’s eyes widened when he witnessed the other guy actually growing. As impossible as it seemed, the other gym goer sprouted up in height, his muscles also packing on some serious size. His pecs plumped out even more and his arms took on some more consider meat. 

“What the fuck?” Derek muttered, freezing when he heard his voice. It was void of any baritone, making his voice sound lighter and almost squeakier, as if it had shot up a few octaves. 

Then the horror slowly dawned on Derek that the other guy wasn’t just growing, but Derek was also shrinking.

Derek watched as his line of sight kept slipping lower and lower, until he was staring directly at the other man’s plump pecs. It didn’t stop there though, as all of Derek’s muscles began to deflate. 

“What the fuck’s happening to my muscles!?” Derek squeaked out in his smaller voice, holding his arms out in horror as his biceps steadily grew flatter.

Derek was helpless to do anything except watch as all of his hard-earned muscles grew flatter and near nonexistent. His arms shrank until they looked like unremarkable sticks, lacking any bulges whatsoever. His pumped up pectorals gradually flattened as they shrank against his chest, looking smaller and smaller until his entire torso was flat— lacking major pecs or even any abs. Even his legs thinned out as quads and calves deflated, growing smaller until Derek had little twigs to stand on.

To add insult to injury, Derek paled as he squirmed and felt an uncomfortable bagginess in the front of his boxers, the front of his shorts looking flat.

When he was finally done shrinking, Derek stared at his skinny body in shock and horror, estimating that he must’ve lost well over fifty pounds of pure muscle, and that he had to have stood at a measly 5’3” now.

“Wh-what did you do to me?” Derek roared, but his lighter voice didn’t hold any sort of threatening quality to it at all. In his frustration, he tried to charge forward and pummel the now larger man, but as he swung his tiny fists at the man’s massive bulk, the other guy didn’t seem phased.

The big gym bully just snickered. “Sorry, Little Man,” he scoffed, gently shoving Derek away, yet the incredible difference in strength sent the tiny alpha stumbling backwards until he fell on his tiny butt with a thud. “There’s only room here for one gym alpha.” 

To illustrate his point, the larger man lifted his powerful arms and flexed his massive biceps which flexed to the size of small melons, easily out sizing Derek’s tiny stick-like arms.

Out of humiliation, Derek took off, sprinting out of the gym in a frenzy, embarrassed at how there was a lack of dangling sensation between his legs. He hurried into his Camaro and nearly wailed as he had to readjust his seat closer to the wheel because his shortened legs couldn’t reach the pedals.

As the tiny man sped off, a large bodybuilder entered the gym, his large muscles oddly already starting to burn the second the stepped foot inside…

Day 17: Nippleslüt

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17

Alpha Derek Hale was taking a shower, a little irritated that he was rock hard and his husband was working the nightshift. Normally whenever Derek got a little frisky, he was all too happy to rush over to Stiles and go to town. However, he was a little miffed that he was all cocked and loaded, yet he was stuck all by himself with just his hand.

“Damn it,” Derek growled as he pumped away at his throbbing cock, even using some of Stiles’s shampoo to help do the trick.

Still, jerking off just failed in comparison to actually fucking. 

Derek was about to just give up and turn the water to ice cold when he spotted an unknown blue vial in the shower. Picking it up, he eyed it and read out the chicken scratch writing on the label that read out Liquid Lust. 

“‘Liquid Lust’?” Derek scoffed, rolling his eyes at his husband’s antics. Stiles had been practicing potions with Deaton, and every so often, Derek would find remnants of his experiments around the house.

Still, wanting to encourage his lover’s endeavors, Derek opened the vial and sniffed at the concoction. It reeked of musk, making the alpha gag and flinch.

Unfortunately, Derek’s jerky movements caused him to lose grip of the tiny vial in the shower, leading it to falling out of his grasp.

“Fuck!” Derek huffed as the smelly liquid fell out of the bottle and landed all over his hairy chest. It splattered across his pectorals, seemingly absorbing straight into his skin. The musky aroma clinging to Derek like it was emanating from him directly.

Immediately, Derek felt his nipples go hard. The little nips perked up before actually stretching out and elongating, inflating until they were large and nubby, looking like a pair of thumbs attached to his chest.

“What the hell?” Derek gasped as he looked down at his altered nipples. He tentatively reached up with one of his hands to prod at them. “What kind of potion is this— OOoohhhh!”

Merely grazing his fingers against his enlarged nipples sent a ripple of pleasure throughout Derek, his voice breaking out into a moan as his knees buckled. His cock throbbed even more, leaking precum. It was like a surge of pleasure never felt before. No amount of sex or jerking off had ever felt nearly as good as just touching his nipple just had.

“Wha-what the fuck is going on?” Derek panted, his meaty, hairy pecs heaving up and down as he struggled to catch his breath. His nipples seemed to burn with want, their own hardness competing with his cock’s, demanding attention from the alpha.

Almost unable to control himself, Derek reached up with both hands, running his thumbs over his hard nubs.

“Uuugghhh!” he squealed, his head rolling back as he toyed with his chest. The pleasure was mind-numbing, and Derek was helpless to do anything besides rub his nipples.

This soon turned to him grabbing a strong hold of both of them with his hands, lightly tugging on his huge nipples. It felt as if Derek had two cocks on his chest, his ignored dick bobbing uselessly between his meaty thighs as he pinched his big nips.

“Oohh fuuuck,” Derek bellowed out, the normally silent guy unable to stop moaning loudly, his deep voice echoing throughout the bathroom. “Holy shit, that feels so good— UUGHHH!”

Derek nearly shrieked as he came, his cock erupting and spewing out globs of cum that splattered against the linoleum in the shower. Basking in the post-orgasmic bliss, the werewolf felt as if he’d just shot the largest load of his life. He couldn’t help but chuckle in disbelief as he tried to catch his breath.

“Holy shit,” he breathed, rinsing away his cum off the walls. His nipples remained perky and hard, and after masturbating by tugging on them once more, Derek finished his shower and toweled off.

He wiped the steam away from the mirror and frowned when he saw that his nipples were still huge and hard. They poked noticeably off his chest, looking ridiculous on his muscular, alpha male frame.

“Um, maybe this’ll wear off in the morning?” he guessed as he glanced at the vial of the liquid lust, finding no other information about it on the bottle. 

Derek stumbled over to his bedroom, biting down on his lower lip at the shiver that traveled down his spine as the cool air from the A/C blew over his hairy chest, caressing his hard nipples. Just that light sensation was enough to make his cock begin to stir back to life, but he tried to ignore it.

He walked over to his shirt to try to cover his chest, but that proved to be another problem.

“Uuughh!” Derek moaned out again as soon as he tugged his shirt on. His nipples poked against the fabric like crazy, and just the cotton running over the nubs was enough to cause his cock to go erect and shoot out cum.

Derek had to rip the shirt away off of him, panting as he gained a reprieve for his sensitive chest. “What the fuck’s happening to me?” he gasped, his nipples almost simmering in the air as they begged for his attention some more.

That night Derek barely got any sleep at all. He would try to lie down on his back, but whenever the covers brushed up against his hard nipples, he’d go rock hard and have to tug on his nips to ease his horniness. Whenever he tried to lie on his front, it led to the alpha uncontrollably squirming against the mattress, moaning loudly as he ground his chest against the hard mattress, loving how it felt to rub his nipples against it, but also humiliated over what a huge nippleslut he was turning into.

“What the fuck am I supposed to do with these?!” he roared in frustration, looking down at his big nipples. 

When morning came, Derek was slightly relieved to hear the front door opening, meaning that Stiles had come home.

Derek leapt out of the cum-covered bed and raced downstairs to his husband, eager for some answers.

“Hey, Der— what happened to your nipples?” a tired-looking Stiles asked from the entryway once he saw the large nubs attached his husband’s muscled chest.

Derek gestured down at his nubby nipples with a shaky hand. “I accidentally spilt some of that liquid lust potion of yours on them, and now they’re— this! And they’re super sensitive!” he growled, his cock already starting to twitch at the mere thought of playing with his chest again.

Stiles’s eyes widened. “You messed with my potion?” he gasped in shock. “That was just a test. I don’t know if there’s a cure for it.”

Derek paled. “So I’m stuck like this?” he asked, looking down at his hard and sensitive nipples, imagining a life where he’d have to walk around constantly shirtless with his massive nubs on display. They’re so sensitive that he seriously doubted that he’d ever be able to get off again without someone playing with his nipples.

Stiles frowned for a moment before offering a meek smile. “If it helps,” he said, slowly reaching up, “I could play with them, if you’d like?”

He reached up and ran his thumb over one of the nubby nipples, and Derek instantly swooned.

“Ooohhh,” he moaned, his cock going straight to attention. “P-please, play with them some more.” He leaned forward and shoved his chest towards Stiles, looking forward to spending the day having Stiles play with his enlarged nipples, the nubs already tingling with anticipation.

Day 21: Centaur

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19 │ 20 │ 21

“Fuck!” Derek roared as he stormed into the yard, hands clenched into tight fists. 

The werewolf was irritated over having nearly lost control of his inner wolf, and nearly wolfing out in public. Derek and Stiles had been out on a simple dinner date, when stupid Jackson had to show up and be his usual douchey self. Normally, Derek was able to keep his lupine instincts in check; however, the second that stupid Jackson had placed his hand on a clearly annoyed Stiles’s shoulder, Derek had seen red. He’d shot out of his seat and had unleashed a fearsome snarl, even baring his massive werewolf fangs in the jerk’s direction.

It had managed to get Jackson to cut his crap, but the action had also accidentally caught the attention of other patrons in the restaurant, who’d only stared awkwardly/fearfully in Derek’s direction. The ceaseless staring had totally ruined the night, and Derek had dragged Stiles out of there early, much to his chagrin.

“Der!” Stiles called out after the stomping werewolf. “It’s fine, really!”

Derek was still seething. Sure he was irritated with Jackson, yet he was more so angry with himself and how his lack of self-control had ruined his date with Stiles. Thinking about it more only served to bring out an onslaught of more anger-inducing memories about how being a werewolf was a pain in Derek’s ass.

His jaw clenched, Derek just huffed in annoyance. “It’s not fine,” he pouted. “And this whole werewolf bullshit is something that’s just going to keep causing us trouble.”

Stiles frowned and placed a tender hand on his boyfriend’s shoulder.

“Sometimes,” Derek huffed, “I wish I wasn’t a werewolf.”

On cue, a streak of light flickered through the night sky as a shooting star bolted across.

Immediately, Derek flinched as he felt a warm travel throughout his body. The first thing he noticed was that his pants were starting to grow uncomfortably tight. 

“What the hell…?” Derek wondered aloud as he looked down at himself. HIs eyes went wide as saucers when he saw his altered bulge in the front of his pants. 

His normally proportional six inches had somehow elongated, creating what looked like Derek was stuffing a ripe grapefruit in his boxers. It was obscenely large, and between his thick thighs, Derek felt balls that had to be the size of lemons. Worse was that back of his pants felt as if they’s burst at any moment.

Looking over his broad shoulder, Derek gasped at the caricature of a butt that was attached to him. His perky cheeks had somehow managed to balloon out to a crazy size, pushing further out with each second.

In his panic, Derek ripped off his pants, his breath getting caught in his throat at what he saw.

Never being one lost for words, Stiles gasped out, “Holy crap, Der! You’ve got a horse cock!”

Derek’s cock had grown to at least fifteen inches, and it was nearly as thick of his beefy wrist. His balls had swollen up to resemble baseballs. The werewolf didn’t have time to focus on that as he felt his weight being yanked back due to the increasing size of his booty.

His legs stretched out longer, causing Derek to sprout up at least two more feet in height. All he could do was stare in disbelief at his changing body, his heart beat loudly in his muscled chest as he wondered what was happening to him. His throat went dry as he witnessed his toes fusing together, his nails hardening to form hooves. 

His butt grew so big that Derek stumble back and almost fell, but he was caught by something.

Stiles’s wordless gasp mirrored his own as he looked back and saw that he’d grown an extra set of legs to offset his elongated backside. Derek blushed at how he must’ve looked, having his regular-looking torso sitting atop a lower half that was stretched out with four legs needed to keep it upright.

Derek’s altered lower half began to itch as thick, black fur sprouted all over it, covering every inch. It was glossy and looked shiny underneath the moonlight. As a final touch, Derek winced when he felt his distended backside tingle as he sprouted a long tail that swished back and forth.

The warmth finally dissipated, and Derek also felt an odd calm inside of his head, like his inner wolf was finally silenced.

“What the fuck just happened?!” Derek panicked, taking an awkward step forward in his new body, his hooves clacking loudly on the ground as he struggled to get used to walking. As he moved, his huge cock dangled around freely, making his face crimson.

Stiles’s mouth was agape as he looked over his changed boyfriend. Derek’s long legs were thick with muscle, which flexed with animalistic power with every heavy step he took. “Der,” he gasped, “you’re a centaur!”

“A what?” Derek groaned, pinching his nose in irritation. “When I said that I didn’t want to be a werewolf anymore, that didn’t mean that I’d rather be a centaur instead! How the fuck am I supposed to hide this thing!?” He gestured at his horse ass and cock, which were humongous and definitely would prove to be difficult to keep from prying eyes.

Derek stopped and sniffed at the air, still maintaining a keen sense of smell. And a curious aroma was wafting off of Stiles in waves.

“R-really?” Derek asked incredulously.

Stiles bit down on his lower lip and shrugged. “I played a lot of fantasy RPGs, and always liked the centaur characters… like, a lot.”

Derek felt his shock slowly fade, and he couldn’t help but grin coyly at his boyfriend.”C’mere, I’ll give you a ride,” he chuckled.

Stiles eagerly took his hand and hopped up onto Derek’s new back, wrapping his arms around Derek’s human torso. 

Derek marveled at how weightless Stiles felt as he carried him, and he began to trot towards the house… his swaying horse cock getting harder and harder. He just hoped that Stiles knew some special stretching techniques.

Day 10: Bear

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10

Derek and Peter Hale groaned as they waddled off the beach towards their car.

Just moments before, the two werewolves had been toned men researching some strange disappearances in the area. Locals would say that men would go and visit the infamous Bear Beach, only to be never heard from again.

Peter winced at the odd feeling of his beefy arms resting atop his lats. “I’m just saying, Almighty Alpha,” he sneered in Derek’s direction, “that maybe there’s a reason the place was called Bear Beach.”

Derek just grunted, not used to the way his rotund, hairy belly jiggled with every step he took. “I thought it was just a name…” he grumbled under his breath, a growl barely detectable.

Peter scoffed and gestured back towards the shore where loads of beefy hairy men lumbered around clumsily, as if they were learning how to walk. “That didn’t tip you off?” he huffed. He wanted to argue more, but instead tensed up as a slight breeze wafted over the two of them, his chest hair being billowed by it.

Derek gritted his teeth as he tried his best to ignore the tingling the breeze caused on his nubby nipples, making his cock start to stir in his tattered shorts.

The very second Derek and Peter had stepped foot on the elusive Bear Beach, they’d immediately felt themselves beginning to change. The first thing the werewolves noticed was the way their jaws had sprouted thick beards, soon followed by hair covering the rest of their bodies— especially their chests. Before either of them could even think to get away from the beach, both of their bodies exploded with flesh. Muscles inflated, but were quickly engulfed by a thick layer of fat that seemed to be centered on their new guts. Their shirts had ripped to shreds, showcasing their massive, pillowy pecs that were capped with large and sensitive nipples. However, their big bellies seemed to be the focus of their growth, making it look as if both of the werewolves had swallowed yoga balls. Derek and Peter’s guts protruded out in front of them, obscuring the view of their own lengthened cocks that dangled crazily as their widened thighs rolled over each other with every step. Even their backs had widened as their large arms puffed up, giving each man a roundish, yet muscular, appearance.

The two werewolves had been turned into total bears simply by stepping foot on Bear Beach.

As soon as the shock of their transformation wore off, Derek and Peter were alerted to the fact that every other man on the beach seemed to share their shocked expressions— all of them looking down at their own massive, hairy form in confusion.

Now the two bear werewolves waddled back to their car, trying to get the hang of moving around with large thighs constantly colliding with one another.

“We need to figure out a way to fix this,” Peter grunted as he poked at his big belly. “I don’t think any of my designer shirts will fit.”

“You poor thing,” Derek snorted, freezing as soon as he heard a loud rip and his shorts finally gave way to his thickened lower half.

The tattered fabric fell to the ground, revealing the alpha’s thickened cock that was at least nine inches and about as thick as a soda can. Not to be outdone, his large hairy ass had ballooned to an exaggerated size, looking like two fuzzy basketballs were strapped to his back.

“Damn it!” Derek roared as he stomped his foot in frustration, flinching as the movement sent a ripple through his massive butt, gut, and pecs. He blushed like crazy. “L-let’s just get out of here.”

The bears lumbered towards Derek’s Camaro, but they had a hard time squeezing their unwanted bulk inside.

Peter, being the smaller of the two, had an easier time, but he still struggled. He wasn’t used to the feeling of having a large gut resting on his lap when he sat down, and he was annoyed at the way his seatbelt completely disappeared between the crevice of his hairy pecs.

Derek had a much harder time. It took all of his cunning to wedge himself into the driver’s seat. He had to shove the seat all the way back, and even at its furthest, his furry belly still pressed against the steering wheel a little bit. Whenever he gulped in a large breath of air, his gut would push out slightly and tap the horn, making him cringe. Worse was that whenever he turned the wheel, his beefy arms would brush against his nubby nipples, making him stifle a moan. It was obviously that his bulk turned him on despite himself, as his humongous cock stiffened and began to bob out at an angle due to his large belly.

“Hopefully Stiles can figure out a way to fix us,” Peter moaned, squirming in his seat as the car’s A/C blew over his mountainous pecs, feeling like someone was running their fingers through his chest hair.

“Yeah,” Derek grunted as he accidentally jostled a nipple again, “…or maybe we can squish him between our bellies first?”

“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 cocked 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 cock, 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 cocky 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 shit, 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.
