Happy Halloween everyone! I hope you all enjoyed this Derek Hale Tf Marathon! It was so much fun to make, and I hope that you all liked what I put out!

-- -- --

Actor Tyler Hoechlin filtered through some emails to waste time before he had to get ready. The actor was supposed to make an appearance at some celebrity Halloween party for photo ops. He wasn’t above taking a picture here and there, but he hadn’t even began to think about a costume, nor had his assistant just grabbed one for him.

“I could just wear a bedsheet and go as a ghost?” Tyler chuckled to himself, thinking that it’d be so lame that it’d be good.

He deleted several emails from casting agents who thought that he’d be great in one of their low-budget horror movies that was supposed to go straight to steaming services. Tyler couldn’t help but grimace at doing anything horror related.

After spending so many years being cast as Derek Hale on Teen Wolf, the last thing he wanted to do was something spooky-ish, lest he risk being typecasted. Already, the actor played Superman on Superman & Lois, but he still had several people on the street referring to him as “Derek”. Of course, Tyler was grateful that so many fans appreciated his work on the MTV series, but there was a part of him that was ready to let the role go.

Which was why he’d frowned deeply at the email from Jeff Davis, the creator of Teen Wolf. Tyler begrudgingly clicked on it, scanning it a little until he got to the reason for the reaching out:

“…MTV is interested in rebooting the Teen Wolf series, and after the negative reception of the movie, the producers have decided not to count it as canon. Can we count on you to return as Beacon Hills’s resident Alpha, Derek Hale?”

Not even bothering to respond to it, Tyler moved the mouse towards the garbage icon to delete it. Before he could click it, his laptop screen flickered and an odd electric shock sparked out, actually shocking Tyler.

The actor recoiled his hand at the sensation, the electric shock sending a tingling feeling throughout the rest of his body for a brief moment.

“What the hell?” Tyler wondered aloud. He closed his laptop and shoved himself away from his desk, making a mental note to buy a new laptop tomorrow since his was obvious short-circuiting. 

He glanced at the clock on the wall and sighed, seeing that he was supposed to start getting ready for the party. Tyler rubbed his temples and walked towards the bathroom so that he could start getting ready. 

As he undressed, the actor could feel a little apprehension starting to seep into his bones about attending the party. The normally social Tyler Hoechlin, for some unknown reason, began to frown at the thought of being at a stuffy Halloween party that was going to be packed with people, wall to wall. The thought of being trapped in a room, shoulder to shoulder, with other people made Tyler shudder, and he began to think of reasons to bail. He thought that it was odd, but he chalked it up to his social battery just being abnormally low that night.

Still, Tyler told himself that he couldn’t just be a no-show. He’d promised his friend and previous costar, Dylan O’Brien, that he’d show up and the two could catch up over a drink.

Tyler could’ve sworn that his heart started to race in his chest for some reason, his limbs tingling with excitement. “What’s going on?” he mumbled to himself, confused as to why he seemed to be so giddy to see Dylan. “It’s just Stiles. I saw him last week…”

He coughed and cleared his throat, having no clue why he’d accidentally referred to Dylan as his old character, Stiles. Tyler shook it off and hopped into the shower. As he bathed, Tyler couldn’t seem to get Dylan out of his head.

“What is going on with me?” he asked himself, wondering why he couldn’t get the man’s dimples out of his mind. What was even weirder to the man was that his cock started to plump up, sticking straight out in front of him.

Tyler had never had a gay thought in his life, and despite seeing all of the Sterek fan art online, he’d never entertained the thought of him and Dylan together. Yet, for some unknown reason, the more he pictured his toned, mole-spotted body, his cock throbbed even harder.

“Fuck it,” Tyler grunted as he wrapped his fingers around his cock, pumping away.

Tyler was so lost in the pleasure that rippled throughout his body as he jerked off, bellowing out low moans the entire time. His free hand ran over his muscled chest, his fingers running through the thick pelt of chest hair—

“Wh-what?” Tyler grunted as he looked down, still playing with his throbbing cock as he stared down at his previously smooth chest. Despite having just shaved his pecs earlier that morning for some pictures as the smooth-chested Superman, Tyler’s chest was now covered in thick, black chest hair. The hairs covered his meaty pecs and ran down his stomach, connecting to his bush by a noticeable happy trail. “What the hell’s goin’ on?”

Tyler’s confusion was briefly forgotten when all of his large muscles tensed up, and his cock erupted with a spray of cum, shooting a large load against the linoleum of his shower. 

The stud was left panting, leaning against the other wall of the shower as he tried to catch his breath. Tyler ran a shaky hand through his wet hair, trying to piece together the fact that not only was his chest hairy, but he’d also just jerked off to another guy— one of his past costars at that.

“I guess Stiles is kinda cute,” he begrudgingly muttered, flinching for a second. “Um, I mean Dylan.”

Tyler finished up his shower and dried himself off in a daze, struggling to wrap his head around what was going on. He knew that something was up, but whenever he tried to concentrate on it, a new growing part of his brain told him not to worry about it. Even as he dried off his hairy chest, his panic that he knew should’ve been there was barely audible.

The actor was puzzling over it as he lumbered back to his bedroom to get dressed. He opted to grab a nice designer suit of out his closet, one that was supposed to make him look like 007. Yet, when Tyler pulled on the white button shirt, he huffed in irritation over how tight it felt.

“Damn it,” he grunted, unable to close the top four buttons of the shirt over his broad chest muscles. He tried his best to suck in his stomach in order to make himself smaller, but his fuzzy pecs were too large to fit into the tiny shirt. His wide back muscles were far too wide, and his biceps threatened to tear the expensive fabric to shreds. Tyler could’ve sworn that the shirt had fit him perfectly at the store, yet now it was at least two sizes too small for him.

With an annoyed huff, Tyler tossed the shirt to the floor and stomped over to his wardrobe to find something that would fit over his muscles. As he stared at the expensive clothes in his closet, Tyler couldn’t help but feel a large bubble of animosity start to form in his gut. The thought of parading around in such garish and over-priced threads was almost repulsive to him.

Without a second thought, Tyler hurried over to his dresser and yanked on a tight, gray tank top that barely fit over his large muscles. He pulled on some worn blue jeans that hugged his butt nicely. As the finishing piece, Tyler snatched a black leather jacket out of his closet and shrugged it on, feeling much more at home in it than he would some brand name suit.

Tyler paused to look at himself in the mirror before exiting his house, noting that he looked like he was wearing his usual outfit that his character Derek Hale wore on the set of Teen Wolf. He snickered and rolled his eyes, but then gasped.

“What the hell…?” his voice trailed off when he leaned in closer to the mirror, his eyes honing in on his teeth. As impossible as it seemed, Tyler could’ve sworn that his canines were bigger. They stood out much more prominently than the rest of his teeth, looking like the actor was wearing caps over them, trying to make them look larger and sharper. “I, uh, I guess these are supposed to be the sharper teeth… Shit!”

Tyler jerked back in surprise at the way his smooth, freshly shaven chin was now covered in a trimmed beard. The way his sideburns connected to it indicated that Tyler must’ve been growing out his facial hair over the course of a few days, maybe even weeks. However, he knew for a fact that he’d shaved his face not even an hour ago, letting him know that something was indeed wrong.

In disbelief, the hairier hunk grabbed at the hairs covering his chin, shocked that they were real and attached to him.

His heart began to race in his beefy chest, but he was quickly distracted when his phone buzzed in his pocket. Despite himself, Tyler snatched it out and glanced at the screen, his stomach doing flips when he read that it was a text from Stiles/Dylan.

Hey! I’m at the party! You’re coming, right? it read.

Tyler couldn’t ignore the giddy excitement that rippled through him, and he caught himself smiling like a goofball, his larger canines poking out of his mouth.

On my way, he responded, grabbing his keys and leaving his house. 

Tyler rushed over to his garage and opened the door, not even thinking twice before hopping into his black Camaro instead of his Tesla before he sped down the street towards the party, eager to see Stiles— or Dylan.

He floored the gas pedal as he rushed to the party, irritated when he hit a red light. Tyler groaned impatiently and rested his head against the headrest in irritation. His eyes glanced towards the rearview mirror, and Tyler gasped at what he saw.

He almost tore the rearview mirror off of its fixture as he leaned closer, seeing that his brow appeared much more prominent than it should’ve. That, and his eyebrows were missing for some reason. His ears had elongated, ending in points that protruded far off his head.

Tyler ran a disbelieving hand over his facial features, feeling ridiculous. He had just enough awareness to recall looking in the mirror on the set of Teen Wolf, seeing the same exact look whenever he was made up into Derek Hale’s beta form. Yet, he could feel the nerve endings whenever he touched his new canine ears, paling at what that indicated—

HONK! 

The car behind him blared its horn as the light turned green, snapping Tyler out of his panic.

Tyler just bared his teeth in the mirror and continued on his way. All of the cars on the road, the bright lights of the city, and the too poppy songs on the radio all seemed to get under the stud’s skin, and a firm scowl planted itself onto his handsome face.

It wasn’t long until Tyler pulled up in front of a large convention center that had a valet service up front. He stopped and got out of his Camaro, unable to hold back the intimidating snarl when he tossed the valet his keys.

“There better not be a scratch on it when I get back,” he muttered, noting the deeper quality to his voice. He cleared his throat as he walked up towards the entrance where a large bouncer stood, clipboard in hand.

“Name?” the bouncer asked.

“Derek Hale,” Tyler answered automatically, flinching and clearing his throat again. “Sorry about that, my name’s Der— er, Tyler Hoechlin.” He didn’t know why saying his name seemed like some Herculean feat, the actor having to clench his fists in order to get it out of his mouth.

The bouncer simply looked down at the list on the clipboard before nodding and ushering Tyler inside.

Tyler rubbed at his temples as he tried to piece together what was happening. However, the second he stepped foot inside, all of his senses appeared to have heightened as they were all assaulted at once. 

Tyler winced at the onslaught of stimuli: the lights in the room were far too bright and he had to nearly squint in order to adjust his sight; the music was blaring out of the speakers, blasting at a near deafening volume; and the stench of overpriced alcohol singed his nostrils, making him grimace. The stud was ready to about face until a familiar scent wafted by.

It took a few seconds for Tyler to realize that he’d been sniffing at the air like a search dog, blushing once he’d been made aware of the other celebrities eying him confusedly. Still, the familiar smell of curly fries alerted him to someone else’s presence, and he found himself barreling through the crowd towards the source.

Tyler’s gaze honed in on Stiles, the cute guy standing over by one of the tables. He was dressed in a suit that had a red coat that made Tyler’s heart flutter in his chest. Immediately, he felt his scowl starting to loosen up the slightest bit, and the more he approached, the quicker Tyler noticed the other guy talking to Stiles.

“Grrr…” Tyler growled out of instinct. As soon as the animalistic sound left his lips, the shocked stud slapped a hand over his mouth. He had no idea why he’d literally just growled like a dog, but once he looked back over at Stiles and the other man talking, he couldn’t prevent the sound from uttering from his lips once more, his large chest vibrating from the noise.

Stiles picked up on the noise and looked over in his direction, smiling and waving him over. “Hey!” he called.

Tyler ceased growling and couldn’t prevent the wide smile from growing on his face as he hurried over to his boyfriend— or past costar. As Tyler was trying to figure out why he was so eager to see the other guy, he wasn’t even aware of the fact that he wrapped a possessive arm around Stiles’s waist, pulling the smaller guy closer into him.

Stiles turned to the other man. “Jeff, you remember Derek, right?” he asked before furrowing his brow in confusion.

The other guy just looked over at Tyler and nodded. “I sure do,” he grinned, holding out his hand for Derek to shake. 

At first, the werewolf just sneered at the other man’s hand, jealousy still coursing through his veins. However, after a slight nudge from Stiles, Derek begrudgingly took it and squeezed it tightly, enjoying the slight wincing from the other man. “Nice to meet you,” he grunted.

Jeff didn’t look too fazed. “As I was telling Dylan, er, Stiles over here,” he said, “I was hoping to hear more about your stories in Beacon Hills. I’m with a large production company that would love to—”

“Not interested,” Derek interrupted, having absolutely zero desire to have his pack’s business advertised in any manner. He was as anti-social as they came, and the idea of talking to some big shot production guy made his headache grow.

Jeff frowned. “…yeah, I guess I did write him like this…”

Derek ignored that, and instead held on tightly to Stiles as he led him out of the crowd of people and towards the exit. They left the convention center and handed the valet the ticket.

“Der,” Stiles piped up, looking just as confused as he was, “um, how the hell did we get in LA?”

Derek’s brow furrowed too as he scratched at the back of his head. He felt like something was wrong, hearing some quiet voice in the back of his head that said that he wasn’t an alpha werewolf. For a brief second, his hairy muscles felt far too big and he wondered why he was so turned on by another man. However, the voice was immediately silenced when Stiles interlocked his fingers with his.

“No fuckin’ clue,” Derek finally said, shaking his head as he took the keys back from the valet. He and Stiles got into the Camaro, and Derek sped down the street back towards Beacon Hills. 

The alpha werewolf rested his arm around the headrest of Stiles’s seat, the motion making his large biceps stretch his leather jacket slightly. Stiles leaned in closer to him, resting his head on his broad shoulder. Derek couldn’t help but puff out his hairy chest with pride, his inner wolf howling with content.

Derek Hale smiled widely, absolutely loving his life.

31 Days of Derek Hale

Day 18: Cockgrowth

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

Derek was an alpha werewolf, and with that, he was seen as the epitome of lupine masculinity. He towered over the other male werewolves in his pack and his muscles were always larger, more so due to his alpha genetics. He couldn’t help but also be turned on by the incredible size difference between himself and his boyfriend, Stiles. Derek was almost two feet taller and almost twice as wide muscular-wise. Derek Hale was an alpha through and through, with one tiny exception.

Derek’s cock was only four and a half inches.

Being below the national average for humans, Derek was humiliated over his subpar size. Over time, he’d fallen into the trope of being the big, mighty alpha who would pick on the smaller guy as a means of compensation for his size. And he’d counted himself extremely lucky that his boyfriend, Stiles, had been a virgin when they’d started dating, and therefore wasn’t really aware of the fact that his boyfriend’s dick was only about one inch away from being considered “micro”.

“Babe, do you think I’m small?” Derek frowned one night, looking down at his tiny dick that barely tented out his boxers.

Stiles, oblivious to his boyfriend’s inner turmoil, simply shrugged. “Don’t worry, Derek,” he’d smiled. “You’re the perfect size for me.”

“That’s not what I asked…”

One night, Derek had seen a mysterious Internet ad that promised “Significant Penile Growth” through some expensive pills. Desperate, Derek had immediately grabbed his credit card and ordered the pills. Once they arrived to his house, Derek wasted no time in ripping the package open and swallowing down a few of the tiny, blue capsules.

After swallowing the pill, it didn’t take long for Derek’s tiny cock to go rigid. The pert little thumb was rock hard, feeling as if Derek was harder than ever. His cock throbbed like crazy, and the werewolf barely registered any thought before his hand traveled south to wrap itself around his small cock and begin jerking off.

Derek couldn’t help but moan loudly as he toyed with his hard cock, his brain going numb from the pleasure that ripped throughout his muscled body.

Suddenly, Derek felt his fingers steadily start to be pushed apart.

“Huh?” he wondered aloud as he looked down at his cock, his eyes widening at what he saw.

As his cock throbbed, right at the pinnacle of hardness, Derek’s cock grew in both length and girth. As Derek jerked off, his cock would throb and jut further away from his body, gradually growing thicker by the second, causing his grip to loosen.

“Holy shit!” Derek cried with glee as his cock grew. “It’s growing!”

The alpha beamed as he witnessed his little cock go from four and a half inches to five, then six, seven, and eight. It thickened up from thin to the girth akin to a soda can, looking large and powerful— just as an alpha’s should.

But then it kept growing.

“Uh, th-that’s enough,” Derek muttered as his cock grew past the nine inch mark, his head almost purple from how hard he was. Precum started to drool out of it like a leaky faucet, and its sensitivity seemed to grow in intensity as did its girth.

Not to be outdone, the alpha’s balls grew in size as well, lowering and thickening to the size of ripe lemons. The thick size of his quads forced Derek’s newly enlarged package to be thrusted forward, his enlarged cock starting to look more like a third arm.

Derek could no longer keep his fingers touching each other, his girthy new cock becoming too large. He had to use his other hand to grip at it, his horniness overwhelming his panic as he jerked off his enlarged cock with both hands. It continued to grow to enormous proportions, finally passing the thirteen inch mark when—

“Uunnghh!” Derek squealed as he came, his muscles tensing up. His huge balls spewed out a large amount of cum, spraying all over the bedroom. It was significantly more than he’d ever came before, cum splattering everywhere at his feet and creating a mess.

It was such an intense orgasm that Derek was left panting, struggling to catch his breath. His meaty pecs heaving, Derek had to press his hand against the wall to steady himself. Finally softening, his mighty cock dangled past his knees, ridiculously long and thick, much past any reasonable proportions.

“What am I supposed to do with a dick this big?” Derek panicked, his eyes wide as he stared down at the massive anaconda that was his cock. Having spent so many years on the other side of the spectrum with a tiny cock, Derek was starting to feel apprehensive about having a cock that was too big… if that was even a thing.

His heart raced in his chest as Derek tried to think of ways he could even get dressed with a cock as big as his was now. There was no way he could manage to fit it into his pants, and even if he could, his huge cock and balls would press against whatever fabric dared to conceal it; its outline would be noticeable to anyone he passed by on the street without a doubt. Images of himself walking around in public with his swinging monster cock flickered into his mind, making him blush with humiliation. At least with his tiny cock, no one could see the outline of his dick through his pants. Now he doubted that any of his pants would even fit him in the first place!

Derek’s shaky hand gave his newly enlarged cock a tentative poke, and his knees buckled at the tidal wave of pleasure that rippled through him at that mere touch. “Oohh,” Derek moaned loudly as his cock rocketed to its full thirteen inches again, looking as thick as his muscular forearm. His head seemed as large as an apple, and it flushed as his cock throbbed with want all over again.

As Derek worried about his new girth, he didn’t hear Stiles walk upstairs and enter the bedroom.

“Hey, Der, can I borrow your chapstick— holy shit!” he gasped in utter shock when he saw the sheer size of his boyfriend’s cock. He wouldn’t admit it aloud, but the first thing that he thought was that there was no way he’d be able to fit that thing inside of him.

“Oh, uh,” Derek blushed, his enormous cock throbbing in front of him. When he turned to the side, it was so large that it knocked over some of the objects on the nightstand, causing them to clatter loudly to the floor. “I just took a pill that said that it’d make me bigger, but I think it worked a little too well.” Despite his panic, Derek’s hard cock twitched as he looked over at his boyfriend, the thirteen inch monster aching with intense want.

“I, uh, I see that,” Stiles mumbled, unable to look away.

Derek scratched at the back of his head nervously. “Do you think you could help me out with this?” he asked, gesturing down at his massive cock. “It’s a bit unwieldy.”

“I don’t think that’ll fit,” Stiles admitted, “but I could try to jerk it off for you?”

Derek took what he could get, and hurried over towards Stiles, his giant cock bobbing wildly in front of him with every step. 

Stiles reached over and grabbed Derek’s large cock with both hands, loving how Derek’s head rolled back as he moaned with pleasure. Thanks to its exaggerated size, Stiles couldn’t wrap his hands around it all the way, so he was left to gripping it as best as he could, having to jerk it off with both of his hands. The head was much too large for Stiles to suck on, but he still leaned forward and playfully ran his tongue over the head, pausing to flick his tongue over the sensitive slit.

The whole time, Derek was rendered a lustful mess. He couldn’t prevent his loud moans from echoing throughout the bedroom, his large cock being extremely sensitive. His eyes rolled to the back of his head, and all of his thoughts turned to mush as he was pleasured. His boyfriend’s hands on his dick was brining much more pleasure than any sex that they’d ever had before, and already Derek was thinking of how his sex life would be different. Given his cock’s new massive size, he knew that he’d be rendered to being jerked off or rutting against Stiles from now on, or even bottoming every now and then.

Derek tensed up as he came, blowing the largest load of his life, leaving him spent and panting. The force of his orgasm left Derek leaning against the wall as he tried to catch his breath. “Damn,” he breathed, “that’s new.” The alpha werewolf’s large cock dangled soft past his knees once more, and as his head started to clear, all he could think about was how much more of an alpha he must’ve looked like given his enormous cock that easily out-sized any other alpha’s.

31 Days of Derek Hale

Day 30: Daddy

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 │ 27 │ 28 │ 29 │ 30

Derek didn’t like being called “Daddy”.

The werewolf bristled whenever his boyfriend, Stiles, would call him it during sex, but would try to brush it off. It wasn’t because of anything too bad, really. Derek just associated the name with being old. When he’d admitted his dislike of the word to Stiles, Stiles understood, but there was a clear disappointment on his face. 

At first, Stiles accepted it and opted to call Derek “Daddy” in his head, yet after one day of looking through one of Peter’s magic books he got a mischievous idea…

Derek came home from work, his muscles feeling slightly achy from a long day at the auto shop. A dazed smile was on his face as he smelt whatever delicious thing Stiles was cooking in the kitchen, mingled with some random incense that was burning throughout the house.

“Hey Stiles,” Derek said as he walked into the kitchen, hugging his boyfriend from behind.

Stiles smiled back, “Oh hey there,” he greeted back, a playful tone evident in his voice. “Did you have a good day at work… Daddy?”

Instead of cringing like usual, Derek was surprised when he felt his cock immediately rocket to life. His seven inches went full mast the mere second he’d heard Stiles call him “Daddy”, even feeling goosebumps erupt all over his body as he shuddered with unfamiliar pleasure. 

“Um, y-yeah,” Derek stammered, his cock throbbing with intense need. He was confused over how turned on he was, but that curiosity rapidly disappeared and his face broke out into a playful smirk. Of course Stiles called him “Daddy”, as he frequently did in the bedroom.

Derek tightened his grip on his boyfriend and playfully rutted his hard cock against his butt.

Stiles pushed back into it. “Oh,” he grinned, “I guess you’re feeling a little frisky, huh… Daddy?”

Derek tensed up as his cock throbbed even more, twitching and leaking precum into his boxers. He felt so tortuously horny, licking his beard-framed lips with want…

Derek cocked his eyebrow and reached upwards with one hand, running it over his previously smooth face. The lower half of his face was covered with a thick, black beard that felt so large that it would’ve taken a few months to grow. It wasn’t Santa big, yet it was big enough to where it went past the typical gymbro beard and bordered Daddy-territory.

“Hey, Stiles, do I…?” Derek’s voice trailed off as he was about to ask Stiles if he looked different, feeling silly all of a sudden.

Of course Derek had a beard. He’d begun growing one the year he and Stiles had started dating, loving the way his beard tickled his boyfriend’s neck as he’d hungrily suck on it. Plus, he loved the way Stiles would shudder as his beard rubbed the inside of his thighs as he sucked him off, making sure he was a good daddy by taking care of his boy’s needs.

Stiles turned around and looked up at Derek with wide, admiring eyes. “What?” he asked.

Derek blushed a little and scratched at his beard. “Nothin’” he shrugged, “just having a weird day, I guess.”

Stiles mock frowned and gave him a quick peck on the cheek. “Well, why don’t you change out of your work clothes, and I’ll finish getting dinner ready… Daddy.”

Derek bit down on his lip as his cock surged once more, feeling as if he was about to explode right there. “Y-yeah,” he panted, jerking back at the sound of his voice. He cleared his throat and tried again. “Be right back.”

As he walked upstairs to their bedroom, Derek could’ve sworn that his voice sounded deeper. It wasn’t exaggeratedly deeper, but the baritone resonated a lot more and there was a more mature quality to it, almost manlier.

The werewolf kept puzzling over it as he entered his and Stiles’s bedroom and began to take off his grease-stained work clothes. As he shucked his pants, his hard cock bobbed wildly in front of him, and he was on the fence between taking care of it real quick and rushing downstairs to ask Stiles to handle it.

Snickering, he opted for the latter and made a move towards the door, clad only in boxers, when he stopped in front of the mirror and gasped loudly.

Derek leaned in even closer to his altered reflection in disbelief, marveling at the array of grays that peppered his hair and beard. As he ran a shaky hand through his salt-and-pepper colored hair, Derek finally noticed the new lines that were near his eyes, indicating the slight beginnings of crows feet.

His heart raced in his chest as he looked like he was much older than he should’ve been, however, his cock throbbed once more and his fear evaporated into thin air.

“What a day,” Derek sighed, rubbing his mature face with his hands. Of course he looked a bit older for his age. He was a total daddy after all, and having a boyish face wouldn’t play into that role. 

Shaking his head at his dazed feeling, Derek went back downstairs, his tented boxers out in front of himself.

When he entered the kitchen, Stiles’s grin grew even wider as he looked his boyfriend up and down. “If you need some help with that, you gotta give me a second because this is boiling,” he said, gesturing at the pot on the stove. “But it shouldn’t take too long… Daddy.”

Derek grunted as his cock spasmed again, a large wet mark starting to form on the front of his tented boxers from his precum drooling out his hard member. He put on a coy smile of his own, crossing his arms in front of his hairy chest. “Well, you better make it quick, ‘cause Daddy’s getting impatient,” he grunted.

Again, Derek felt like something was off as he looked down at his hairy chest. The older hunk could’ve sworn that his chest was naturally smooth and typically devoid of any hair, but that thought was quickly proven wrong as he stared down at his hairy pecs and stomach. In fact, his whole body seemed to be covered in coarse, black hair. It covered his strong arms, thick legs, and even disappeared into his tented out boxers. 

Derek snorted at himself. Of course he was hairy, and he’d always melted at the sensation of Stiles running his fingers through his thick chest hair. He just chalked up his foggy brain to his insane horniness that he felt, his cock aching for his boyfriend to touch.

Derek squirmed in place, his cock twitching madly as Stiles finished up at the stove. Once the burner was turned off, Derek couldn’t contain himself anymore and eagerly rushed forward, easily tossing the smaller guy over his shoulder as he stomped towards the couch.

Stiles laughed. “Damn, I guess you’re really frisky,” he giggled, “…Daddy.”

“Hnng,” Derek bellowed as his cock leaked even more precum, his thudding footsteps sounding heavier and much louder than normal.

For the millionth time that hour, Derek scrunched up his face in confusion as he lumbered towards the couch. The way his thighs rolled over each other as he waddled felt wrong to him. Whereas Stiles felt lighter in his hold for some reason, Derek felt as if his own chest was much heavier than it should’ve been. He glanced downward at his hairy pecs, his eyes nearly bugging out of his skull at the way his bulbous pecs jutted out in front of him, having ballooned to such a large size. They blocked the view of anything south, forcing Derek to stare at his hairy mounds and the tips of his nubby nipples. He blushed as he felt a foreign jiggling at his gut, and upon glancing at his blurry reflection in the TV, he could make out a large, hairy musclegut that his large pectorals rested upon. His boxers had magically disappeared, and the werewolf nearly sputtered at his massive ten inch monster cock that bobbed in front of him. Even his hairy butt had bubbled out, jutting out from his broadened back at a large angle. To finalize his growth, Derek’s arms had doubled in muscle, explaining away at how Stiles felt lighter.

It was hard to deny it now, as Derek stared at his altered reflection. The large muscled up, hairy older man who stared back at him from the TV’s glare. He finally pieced together what was happening: Derek was turning into a total daddy.

And he loved it.

As shocked as he was, Derek’s panic was quickly replaced with lust as he flexed his free arm with power, loving how big and manly it looked. He knew deep down that Stiles had somehow played a hand in this, and he loved him even more for it. Mental images of the two of them out in public, Derek completely dwarfing his smaller boyfriend who called him “Daddy” for all to hear filled him a giddy excitement, and he couldn’t wait to have Stiles run his fingers through his chest hair.

Derek tossed Stiles down onto the couch and loomed over him, smirking hungrily down at him. He couldn’t resist leaning forward and flexing his beefy, hairy muscles. “Who’s your daddy?” he bellowed in his deeper voice.

Stiles could only grin back up at him in anticipation before lowly whispering, “You… Daddy.”

“Uuughh!” Derek grunted as he came, loving how his bulky muscles bounced as his cock erupted, shooting his fat load up onto his hairy pecs. He knew deep down that he’d just cemented his transformation into a muscle daddy, but the second he looked down at his boyfriend, his enlarged cock shot straight back to life, and he pounced, forcing Stiles to take care of his daddy all night long.

Day 19: Action Figure

Derek rubbed his temples in irritation as he wandered through the numerous aisles of the toy store. Aisle after aisle, row after row, brightly colored advertisements and countless useless objects with stupidly high price tags made his headache even worse.

Derek had come to the toy store to find a gift for his boyfriend, Stiles… who he had to point out was a legal adult. Stiles was just a total kid at heart and loved to collect tons of franchise memorabilia, which was something that Derek loved about him. And after falling for the whole “Oh, you don’t have to get me anything” trap last year and having to deal with the fallout, Derek was determined to get Stiles the perfect gift this year.

“Damn it,” Derek growled at the memory of Stiles giving him the silent treatment after his non-gift last year, quickening his pace as he stomped through the aisles in search of something great.

Unfortunately, Derek was having no luck.

“Fuckin’ finally,” he repeated under his breath as he entered an aisle chock full of superhero action figures. 

Derek hurried down the aisle, his eyes scanning the rows of plastic men all over. Each one of them was brightly colored in blaring blues and radiant reds, their over exaggerated muscles looking extremely round and out of the realm of anything humanely possible. Derek’s trademark frown deepened as he searched all over the aisles for the perfect one.

No ordinary superhero would do, especially since Stiles already owned so many. Derek shuddered at the thought of accidentally buying his boyfriend one that he already owned, just to get the side eye and accused of not paying attention.

“Damn it,” the werewolf repeated, annoyed. He frantically began to search the aisle, picking up toy after toy and holding it close to his face studiously. Sure, they were all painted colors and had a variety of “[Insert Random Item]-Man” across the box in bright, blocky letters. However, Derek couldn’t seem to remember which ones Stiles already owned.

In his panic, the werewolf grabbed a white box that contained a blank action figure in it: no facial features or costume painted on at all.

The second his fingers grazed the mysterious box, Derek winced at the odd spark that traveled throughout his body, causing the hairs on the back of his neck to stand up. 

“What the hell was that?” he muttered as he brought his hand up to his face to examine his still tingling fingers.

Derek’s eyes widened as he witnessed his fingers taking on a shiny quality. He scrunched up his face in confusion as his fingers gleamed more underneath the bright fluorescents of the toy store. His heart raced in his chest as they stiffened, becoming immovable as his hand apparently turned into plastic.

“Wh-what?!” Derek panicked as the strange transformation traveled down his arms. Weirder was that the werewolf swore that his muscles plumped up, becoming larger and much more exaggerated before they hardened into the same plastic quality as his hands. His signature black leather jacket vacuumed to his torso as his pecs widened and pushed outwards, becoming skintight. It then started to brighten as it went from slate black to royal blue. His jeans underwent the same changes, suctioning to his buffer legs as they brightened into a cartoonish blue that looked more apt on a superhero, not a regular guy wandering around the mall. Derek winced as his bulge seemingly shrank as it was pressed tightly against him. Derek painstakingly move an almost inflexible arm and patted at his groin, groaning as it felt flat and unremarkable like a Ken doll.

The tingling sensation spread up to Derek’s head, and the altered stud couldn’t help but try to reach up with his plastic limbs. His hair had hardened into a large plastic mold, becoming a lump of black plastic in the shape of his usual hair style. His face felt smooth and unblemished, and he couldn’t help but press both of his hands on either side of his head and give it a little squeeze.  Derek couldn’t hold back his gasp as his head squished and then popped back into shape, illustrating that it made completely out of rubber now.

The werewolf tried to run off, to seek help, but he was stopped by his massively hindered movement. Like most action figures, his limbs were stiff and rigid, their over muscled selves only posable at the main joints.

“Well, well,” hummed an irritatingly familiar voice, “that’s a nice look there, Derek.”

Derek struggled to turn around, his virtually immobile body and larger muscles making movement extremely tedious. He fought back a growl when he saw none other than Theo, the bratty chimera who didn’t hide his crush on Stiles.

The mischievous smirk on Theo’s annoying face was enough to clue Derek into the fact that he was somehow behind whatever was happening to him.

“What did you do to me?” Derek demanded, trying to threateningly stalk forward, but his posable joints made his movements awkward.

Theo shrugged his shoulders. “I was lookin’ for a birthday gift for Stiles,” he snorted, “and I know that he likes action figures, and for some reason he also likes you, so…” He gestured forward at Derek’s new plastic body. “And you’re just about done.” 

Theo snapped his fingers.

Derek felt as if his sense of gravity was thrown as he wobbled on his stiff legs. The shelves in the aisle seemed to grow taller and much larger. However, it quickly dawned on Derek that the store wasn’t growing— he was shrinking.

The werewolf was helpless to do anything besides get smaller and smaller, as his movements became harder and harder to create. Derek’s scowl softened and instead he held a stoic expression as his face hardened. Eventually, the former alpha werewolf had been turned into  ten inch tall super hero action figure, complete with big muscles.

“Perfect!” Theo laughed as he easily picked up the toy Derek, snatching the blank box in his free hand.

Derek inwardly screamed, but was helpless as Theo positioned his plastic arms in a manner that looked like he had his hands on his hips in a heroic pose. He was shoved into the box, and from his frozen position, Derek could barely make out the outside of his prison chasing colors to become bright and alluring. Unbeknownst to him, the outside of the box now read: Superwolf: the World’s Most Muscular and Cranky Superhero!

“Stiles is gonna love my gift,” Theo laughed as he walked action figure Derek over to the cashier.

The whole time Derek screamed at being turned into a toy, and he just hoped that Stiles would figure out a way to help him out… and another part of him hoped that Stiles would like his large superhero muscles.

Day 29: Butt Growth

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 │ 27 │ 28 │ 29

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 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?”
