“Well, well, if it isn’t none other than the infamous Derek Hale,” Sheriff Stilinski sighed as he sat down in the driver’s side of the cruiser. 

Derek just glared silently back through the fence-like barrier that separated the two of them. He huffed angrily through his nostrils, keeping his lips pursed to avoid making the situation any worse for him. The young man wasn’t unfamiliar with Sheriff Stilinski, often running afoul with the old man here and there. It wasn’t that Derek was a career criminal by textbook standards, but he admitted that he didn’t make the best choices. Thus, he had a sort of negative reputation around Beacon Hills, with most of the sheriff department keeping a watchful eye on him.

The cruiser’s engine roared alive, and the Sheriff drove down the road towards the station.

Derek silently steamed in the backseat, perfectly content with not saying a single word.

However, the Sheriff cleared his throat and eyed the werewolf in the rearview mirror. “You know, Derek,” the Sheriff said, his rough voice taking on a kind air, “I’d promised your family that I’d look after you. But for some reason, you just can’t seem to keep your nose outta trouble.”

Derek just grunted, rolling his eyes. He tried to tune out the cop and focus on the woods outside the window. 

The Sheriff continued though. “And,” he pressed, a different tone overtaking his deep voice, “I’ve seen you eying my boy.”

Derek winced and fought hard to maintain his cool, but he could tell that he looked worried as his bushy eyebrows knitted together. Of course he found the Sheriff’s son, Stiles, attractive and it was true that he’d been trying to court him; however, he hadn’t counted on the old man being that perceptive.

“What are you talking about?” Derek tried to play it off, his heart starting to race in his chest.

The Sheriff lowly chuckled. “Derek,” he said, clicking his tongue, “I have my own skills, too. And let’s just say that although I like you and your family, I’m not too happy to have someone like you following my son around.”

Being used to being seen as less, Derek snorted and prepared a sharp retort. However, when he opened his mouth, his eyes widened when no sound came out. He cleared his throat and tried again, but not matter how hard he tried, the werewolf couldn’t utter a noise. He felt his heart start to race in his chest as he tried with all of his might to make the slightest bit of noise. However, every single attempt was futile.

The Sheriff smirked back at the struggling werewolf in the rearview mirror. “But you don’t have a job right now, do you Derek?” he pressed, an odd happy quality to his voice.

“No, Sir,” Derek felt himself respond without thinking. He wondered what was going on— why he could only seem to speak when the Sheriff allowed him to, and why he’d called him ‘Sir’.

“That’s a shame,” the Sheriff added. “You were always so cheery and polite. I would’ve figured you’d be the star employee somewhere by now.”

Cheery and polite? Sure, Derek wasn’t a blatant asshole, but neither of those adjectives described him in the least.

“Thank you, Sir,” Derek heard himself reply again. “I always do try my hardest, but gosh darn, the job market is tricky.” The werewolf’s stomach fell as he heard himself speak in such a dweebish tone. He tried to force himself to cuss out the sheriff, but as soon as the words were almost on his tongue, they’d fled.

The Sheriff cleared his throat and went on. “Well, if you’re interested, the police academy is always taking in new recruits. I think you’d be a good fit.”

Derek wanted to decline immediately, hating the idea of seeing himself strutting around Beacon Hills as some police officer who acts all goody two-shoes and whatnot. “That sounds like an awesome idea, Sir,” Derek happily agreed, and he felt his face stretch out into a giddy smile. He spotted his own reflection in the rearview mirror and inwardly flinched at how dorky he looked being all smiles; however, his attention was quickly diverted when he noticed something else.

Derek’s eyes widened even further when he saw that his jeans and white tank top had completely disappeared from his body. As quickly as his old clothes had vanished, new ones reappeared in their stead. Navy blue khakis were tightly wrapped around his powerful legs, looking almost skintight and like there was barely any extra room in there. His torso had on a navy blue, button down shirt that had the patches of the Beacon Hills Sheriff Department sewn onto the short sleeves. Right above the right pocket was a small silver name tag that read out: “HALE”. A black belt appeared around his waist, equipped with all of his police equipment that he’d need for his new job.

Derek’s smile faltered for a brief second before it took over once again. “Thank you, Sir,” he grinned. “I’ve always wanted to be a cop ever since I was a kid.”

The Sheriff nodded. “I know it, Derek,” he hummed. “I can tell by the way you’ve dedicated yourself to fitness.”

Before he could ponder over what that meant, Derek felt all of his muscles tense up simultaneously. The first thing Derek noticed was his thighs steadily growing larger and rounder, closing the gap between them little by little. However, his line of sight was soon cut off by his growing chest muscles. His pecs inflated and pushed outwards, taking up the remaining room in his shirt until it was skintight— POP! The top two buttons of his police shirt popped off, revealing the new, deep pec cleavage he now possessed. His arms grew in size, his biceps inflating to the size of melons as they bulged with power out of his short sleeves. They rested on flaring lats, giving the werewolf a broad appearance that reeked of masculine power. When he looked back into the mirror, Derek saw his neck steadily broaden in tandem with his shoulders, effectively giving him the appearance of a bodybuilder in a police uniform. 

His heart raced in his inflated chest, but instead of voicing his panic, all Derek could say was, “That you, Sir. Last weigh in, I came in at three-hundred pounds of solid muscle— all for the good of protecting my community.”

The station came into sight and the Sheriff’s own smile dominated his older face. “That’s the right attitude to have, Derek,” he said. “I know you’ll be a great man of the law.”

Derek felt his old self starting to slip, quickly being dominated with the muscled Dudley Do-Right cop he’d been turned into. He grit his teeth to prevent the change from taking over, but it was futile. In a matter of seconds, the old trouble-making Derek Hale was quickly replaced with Deputy Hale: the bodybuilding cop who was as straight-laced as they came.

Derek’s smile grew even more, genuinely this time, as he noticed the station as the Sheriff parked in front.

Derek exited the back of the cruiser, unsure why he’d decide to ride in the back— he probably lost a dare and was playing around with Sheriff Stilinski. The older man was like a father to him, and Derek respected him with every fiber of his being. As soon as the new cop took a step out of the cruiser and felt his large thighs rub against each other and noticed how heavy his pecs and arms were, he cocked his eyebrow in confusion for a moment. Maneuvering around felt awkward, almost as if he was getting used to strutting around in such a muscled body.

Derek snorted and shook his head, knowing that was ridiculous. He worked out religiously and was always super muscled, easily dwarfing all of the other men on the force.

The muscled policeman waddled up to the station, but froze when he saw the Sheriff’s son, Stiles, hanging by the entrance. He felt his heart race in his beefy chest and blush form on his face over how cute Stiles looked. 

“Oh, um, h-hi there, Stiles,” Derek gushed, looking like some lovestruck dork in front of the station for all to see. “What brings you here?”

Stiles paused for a moment, his own eyebrows furrowing for a second. “I came to see my dad,” he mumbled, his eyes running up and down Derek’s bulging form, making the cop’s heart race even faster. “Derek, d-did you… um, this might sound weird, but you look different for some reason. I can’t put my finger on it.”

This time, Deputy Derek shared Stiles’s confusion, and for a flash, the way his body felt so heavy and the sensation of his skintight uniform on his muscles felt all too wrong. However, just as quickly as the feeling had occurred, it evaporated into thin air and Derek’s smile widened even more.

“I just got back from the gym,” he happily gushed, raising both of his powerful arms above his head to form a double biceps pose. The movement caused his massive biceps to curl completely out of his sleeves and bulge with power. “It’s probably the pump you’re noticing.”

Stiles blushed a little as he stared at Derek’s huge muscles. “Yeah, I guess that’s it,” he admitted.

Not wanting to waste any time, while still flexing, Derek blurted out, “Want to do something this Saturday?” he asked. “… with me? Please?”

Stiles wanted to argue, to say that something was definitely different about Deputy Hale. However, his memories seemed to recall seeing the muscled up cop working shoulder to shoulder with his father for quite some time. “Sure,” he finally agreed.

Deputy Hale dropped his arms, letting them rest atop his lats a near right angle. “G-great!” he eagerly stuttered, the giddy new deputy over the moon at the prospect of finally taking the Sheriff’s son out. “I’ll pick you up at seven!”

31 Days of Derek Hale

Day 15: Caveman

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

Derek wasn’t proud to admit it, but he had a little bit of a jealous side.

Nothing brought out the green-eyed monster more than watching some guy try to flirt with Stiles, or even hearing Stiles comment on how hot he thought a certain actor was. The other day, Stiles was talking to Lydia, and he’d mentioned how he’d thought that the new Superman actor was cute. Derek had to swallow down a growl, and he’d not-so-subtly changed into his Superman t-shirt afterwards.

Stiles didn’t seem to mind too much, or if he did, he didn’t say anything. He’d usually just laugh it off and give his husband a big hug, trying to calm him down.

This all came to a culmination when the water heater when out. 

“Der, I had to call a plumber to come fix the water heater,” Stiles told the werewolf. “He said he should be here soon.”

Derek just grunted from his spot on the sofa. He mindlessly munched on beef jerky as he watched TV, clad in just his sweatpants. He was so caught up in watching Alexander Skarsgård swinging through the jungle as Tarzan, that he’d barely heard the doorbell ring. 

“I’ll get it!” Stiles called out as he hurried over to the front door, swinging it wide open. 

“Hello, Mr. Hale,” a deep voice bellowed out, making Derek perk up, “I’m Chase, I’m here to fix your water heater.”

“Oh yes!” Stiles breathed, sounding relieved. “Come in, please.”

Derek turned around to stare down the other man who entered his house, frowning at the muscular stud who followed behind Stiles. The alpha werewolf couldn’t help but narrow his eyes in the direction of the plumber who wore a blue uniform. The young man was so built and muscular that he left the top three buttons of his shirt undone, showing off his impressive hairy pecs. His sleeves were rolled up, allowing his bowling ball sized biceps to curl out of them. In front of his tight jeans was a large bulge that made it look like the young man was smuggling a grapefruit in his pants. And when the plumber walked, his firm butt pressed tantalizingly against his jeans which were so tight that they rode a little low, giving credence to the term “Plumber’s Crack”. His dirty blond hair was combed in that style that made it look slightly messy, but sill manageable, and his lantern jaw was covered in masculine stubble. The dude seriously looked like he’d been ripped straight out of a porno.

Immediately, jealousy surged though Derek and he felt himself leap off the couch and hurry over towards Stiles, wrapping a possessive arm around his waist. He puffed out his own sizable pecs and forced a smile on his face. “Yes,” Derek almost growled, his voice rougher than intended, “please come into our home.”

Stiles shot him a look.

Chase only smirked as he entered the home, his heavy footsteps thudding loudly as he followed behind the couple.

“The water heater’s in the basement,” Stiles babbled on. “It went out last night and the water’s been ice cold ever since. You’re a real lifesaver for coming on such short notice.”

“It’s all part of the job,” Chase said, giving Stiles a crooked grin.

Derek bit down on his lower lip to hold back his snarl. “I could’ve fixed it,” he added hurriedly, “but I have a lot on plate since I run my own auto shop. So you know, management is very time-consuming work that only tough guys can do.”

“Wh-what?” Stiles wondered aloud.

Chase shrugged it off. “Sure,” he coughed. “A lot of wives tend to call me when their husbands can’t fix a simple appliance. It’s nothing to be ashamed about.”

Derek saw red and his fists shook with rage. He had to take a few deep breaths to prevent himself from phasing on the spot and mauling the cocky plumber… when a devious plan entered his head.

“It’s, uh, kinda hot down here,” he stated, forcing a toothy grin onto his face, “why don’t I get us some drinks.”

“I can get them,” Stiles offered.

“No!” Derek hurried, as he practically sprinted back up the basement stairs towards the kitchen. The werewolf tore through the cabinets as he grabbed three cups, making sure to grab Stiles’s favorite Superman glass. He then snatched the jug of Crystal Light out of the fridge before grabbing the secret ingredient from under the sink.

Derek couldn’t help but smile maniacally at the translucent powder that possessed a pink shimmer to it. It was a magical powder that Peter had made, claiming that it would cause “Embarrassing Side Affects that varied from person to person”. Derek had no clue exactly what that entailed, but he figured that annoying, sexy Chase would be the perfect tester to try it out.

The jealous werewolf made sure to pour Stiles’s glass first, setting it far away on the counter so that it wouldn’t come into accidental contact with the powder. That left two unmarked cups, and in his haste, Derek filled them both to the brim with the red Crystal Light. He then dumped a large spoonful of the mysterious powder into one of the glasses, marveling as it immediately dissolved, leaving zero trace of its presence behind. The giddy werewolf was so caught up in imagining all of the humiliating scenarios that played in his head involving Chase, that he put the jug of Crystal Light back into the fridge without memorizing which glass he’d spiked with the powder.

Derek froze as he stared at the two unmarked glasses on the counter, both of hem equally filled up with red juice. 

“Damn it,” he snarled, making move to dump them both down the sink to try again, but then something caught his ears.

The werewolf bristled as he heard Stiles’s laughter echo out from the basement, the deep bellowing of Chase’s annoying voice trailing behind.

With a ferocious growl, Derek dumped a spoonful of the powder into each of the unmarked glasses. He grabbed all three of them and raced back down the stairs, eager to break up the laughing session between the stupid plumber and his husband.

“H-hey, what’s so funny?” Derek asked, forcing a cheerful smile onto his face as he walked down the basement stairs. Despite his grin, his eyes narrowed in Chase’s direction. He walked up to Stiles and handed him the Superman glass that wasn’t spiked with the embarrassing potion.

“Chase here went to Beacon Hills High, too!” Stiles exclaimed. “I knew he looked familiar. We were in the same Spanish class.” He looked over towards the plumber. “You’ve put on some serious muscle.”

Chase held his head up high as he flexed a large bicep. “Yeah, I’ve been getting into bodybuilding,” he grunted. “You should check out my Instagram. I post tons of progress photos there.”

Over my dead body, Derek wanted to say, but instead he held out a glass for Chase. “Here,” he forcefully smiled, “I hope you like Crystal Light.”

“Thanks,” Chase obliviously said, accepting the glass and bringing it up to his full lips. He paused for a second, eying the water heater in the corner of the basement. “Oh, I can see a leak from here.”

“A leak?!” Stiles repeated incredulously, rushing forward to inspect the large machine as best as he could. “Where?”

Chase lumbered towards him, positioning himself way too close for Derek’s liking. “There,” he said, pointing towards a small spray of water.

For the millionth time, Derek was seeing red, beyond irritated that the muscleman was getting close and personal to his husband. In his anger, he briefly forgot that he was supposed to wait for Chase to take the first sip of his drink, and brought the glass up to his own lips to take a large gulp of the sweet juice.

Instantaneously, Derek’s eyes widened when he’d realized his mistake, quickly placing the half-emptied glass onto a nearby fixture. His heart raced in his chest as he waited for something to happen, holding his breath as he prepared for the worst.

“Damn,” Stiles frowned as he examined the leak, “do you see this, Derek?”

“Derek see,” Derek bellowed, his voice sounding much deeper and guttural than normal, making the werewolf flinch in shock. He had no idea why he’d referred to himself in the third person, so he cleared his throat and tried a second time. “Ook!”

Stiles only chuckled, his back still turned to Derek, thinking that his husband was just trying to be cute.

Meanwhile, Derek’s panic grew when he felt himself beginning to itch. He looked down at his chest and gasped as he watched wisps of black hair sprout all over his toned pectorals. The naturally smooth werewolf was stunned silent as he watched his hair thicken, and not just over his chest. He held his shaky hands up in front of his face, paling as hair grew over his arms, traveling towards his wrists and even his knuckles.

Derek felt his center of gravity rapidly shift, and he stumbled on his feet, falling over. He managed to catch himself before hitting the hard ground. Yet, he noticed that he was perched using his knuckles for support, reminding him of those lumbering gorillas he’d seen on TV. He tried to stand up straight on his two legs, but he could make it about halfway before toppling back down on all fours like an ape.

As a final touch, Derek nearly went cross eyed as he watched the bulge in his sweatpants steadily grow larger. The bulge inflated as it grew, causing his enlarged cock to stiffen and snake down his pant leg, looking ridiculously big on his toned, hairy form.

His heart raced in his hairy chest as Derek realized that he’d turned into some sort of monkey man. “Derek feel funny,” he muttered in his deeper voice, bristling at the awkward way he spoke. His thoughts were still coherent, but he couldn’t get his mouth to cooperate with what he wanted to say.

“Huh?” Stiles asked, looking over his shoulder before gasping at his hunched over, hairy husband. “Derek?! What the hell happened?!”

“Ook! Ook!” Derek bellowed, jumping up and down in his crouched position. His blush deepened when Stiles walked up to him, standing tall above his hunched over body.

Chase only glanced over this broad shoulder before shrugging and continuing to examine the water heater.

At the sight of Chase’s glare, Derek felt his possessive side spark once more. However, instead of silently brooding, the werewolf felt himself puff out his hairy chest. His muscles tensed, he beat at his chest with both of his meaty fists, mimicking a large gorilla. Again, he internally winced at his uncontrollable actions, but he couldn’t help it. Derek could only bare his teeth as he beat his chest intimidatingly.

Stiles’s eyebrows lowered slowly as he put the pieces together gradually. “Ohhh,” he hummed, eying the glass of Crystal Light.

Derek stopped beating his chest and cheekily smiled up at his husband. “Ook!” he grunted, nuzzling against the other man’s leg in an attempt at an apology.

Stiles snickered a little bit. “You’re silly, Derek, you know that right?” he chuckled as he ran his fingers through Derek’s hair.

“Ook! Ook!” Derek happily cheered as he bounced in place, his hard cock bobbing up and down wildly in his sweats. It wasn’t his intention to turn himself into some feral caveman, but he couldn’t deny that he liked how Stiles was paying much more attention to him now than he was to Chase.

“Your husband’s weird,” Chase muttered, rolling his eyes at Derek, who only beat his chest in uncontrollable response. The muscled plumber finally brought the glass of red Crystal Light up to his lips, taking a loud gulp.

“Ook!” Derek grunted as he watched the changes happen automatically.

Chase must not have felt anything, but as he drank down the cursed drink, Derek and Stiles stared in awe as the large bulge in front of his pants shuddered before growing less prominent. The previous mound that had looked like a grapefruit grew smaller and smaller by the second until the front of Chase’s jeans were flat and unremarkable.

When the glass was empty, Chase lowered it and wiped his lips. “This tastes kinda funny,” he said, freezing up in fear at the sound of his voice. His usual deep baritone was gone, replaced with a cartoonish voice that was hilariously high-pitched and squeaky, sounding just like a chipmunk’s.

Stiles had to cover his mouth to keep from bursting into hysterics.

“Oook! Ook!” Derek bellowed, happily slamming his fists down onto the ground in victory. He couldn’t hide the dim smile that stretched out his face, and he puffed out his hairier chest with pride.

Chase blushed a little and cleared his throat. “Um, *ahem, what I meant to say, *ahem, what’s wrong with my voice?!” The muscle man clutched at his throat, his face burning red at the sound of his cartoonish voice.

Stiles, unable to contain himself, broke down and doubled over with laughter. “That’s not it!” he guffawed, tears welling up in his eyes at the sight of the squeaky-voice muscleman.

“What do you mean?” Chase squeaked, stomping his foot in irritation, his voice making it sound more like he was throwing a tantrum than trying to be threatening.

“Tiny!” Derek managed to say, bouncing up and down excitedly on his feet and fists, like a chimp at the zoo.

“‘Tiny’?” Chase repeated, still blushing over the sound of his new voice. His eyes followed the direction of Derek’s stare. He gasped when he saw the flat front of his jeans and immediately unbuttoned his pants, shoving them down. The pathetic two inch nub looked completely out of place on Chase’s muscled frame. It was so small and puny that it was barely noticeable in his trimmed bush.

Chase screamed, his voice sounding even higher than before. He yanked his pants up and ran up the stairs in a hurry, exiting the house in a panic.

Stiles continued to laugh for a few more minutes before he was able to slightly contain himself. “That, haha, wasn’t nice Derek,” he tried to frown, but his chuckling ruined the mood he was trying to portray.

Still, Derek hung his head in shame. “Derek sorry,” he muttered in his slow voice.

Stiles smiled down at his husband and ran an admiring hand through his thick hair. “It’s okay, I guess,” he hummed. “You don’t have to be so jealous, Sourwolf. I love you.”

At this, Derek felt himself perk up, his lengthened cock rocketing to attention. The caveman werewolf beat his hairy chest with pride, a wide smile on his dim face. He then reached over and tossed Stiles over his shoulder, carrying him upstairs towards their bedroom as he readied to show his husband just what a wild man he now was.

31 Days of Derek Hale

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…

31 Days of Derek Hale

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?”

Day 08: Cock TF

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

When Derek woke up, all that he could see was darkness, as if there was a sheet yanked over his head. Instinctively, he moved to yank whatever was covering his head, but he realized that he couldn’t move.

Immediately, panic started to seep throughout Derek as he realized that he was practically paralyzed, unable to move a limb. He thought that it was sleep paralysis at first, but eventually he felt himself shift around and being moved without any say so of his own. Derek panicked as it felt as if he was being carried, unable to feel his legs carry him towards something, that fabric still covering his eyes like a blindfold.

“Ready for a surprise, Derek?” a familiar voice asked the alpha.

“What? Theo?” Derek asked, growing angry over what was happening. “What the fuck is going on?!”

“You were always such an annoyingly cocky alpha, so check this out!” Theo chuckled.

The “blindfold” was ripped away from Derek’s face, and the first thing he noticed was Theo’s smirking face. However, it was wrong in the fact that it was much higher up than it should’ve been, as if Theo were several feet taller than the alpha werewolf. That thought was quickly ignored when Derek looked directly into the mirror that he was standing in front of, screaming loudly when he noticed what was wrong.

“What the fuck?!” Derek roared as he stared in horror at his altered form.

All Derek could see was Theo’s long cock that dangled between his thick thighs. However, instead of a regular-looking cockhead, Derek saw his own head attached to Theo’s shaft. It looked as if someone had photoshopped Derek’s head on top of Theo’s cock, editing out his arms and legs.

Theo chuckled as he shifted his hips a little, causing his cock to wag back and forth, and thereby make Derek a little dizzy. “I was so tired of you and your big dick energy,” Theo explained, “so I decided to turn you into my cock. I thought about making you my butt, but I like this idea better.”

“You turned me into your cock?!” Derek repeated incredulously, unable to wrap his head around what was happening. “You better turn me back, right now! You hear me? Now!”

Theo mock frowned. “Don’t be like that, Sourwolf,” he teased. “I’m sure that you’ll love your new life as my cock.” He reached down and fondled himself a little, causing his cock to grow harder.

Derek’s angry face froze, and he wore a stunned look as he felt his new body stiffen. It was as if all of the muscles in his body was flexing in unison, becoming hard and rigid as his new cock body hardened. His head rose and stood out at an angle on Theo’s boner, bobbing the air.

Despite his panic, Derek’s hormones surged throughout his new body and all he could concentrate on was getting off. He was incredibly horny and all he wanted to do was jerk off his new body; however, without his arms, he was helpless and trapped at the chimera’s mercy.

Luckily/unluckily, Theo reached down and wrapped his fingers around Derek’s new shaft body, pumping his fist up and down.

Derek nearly went crossed eyed as his new body was jerked off, feeling as if tidal waves of pleasure were coursing all throughout his altered form. Memories of Derek jerking himself off paled in comparison to having his entire body felt up and played with. All of the nerves in his new body were intensified, forcing every touch on his smooth skin to electrify every pleasure center he owned. Derek couldn’t hold back his low moans as he was played with, almost loving it when Theo ran his fingers over his cock body.

Derek tensed up and felt one of the waves of pleasure inside of him break. A snap ruptured deep within him, and the alpha werewolf felt a pressure building deep within him when—

“Ooohh!” Derek moaned, his jaw opening wide as cum squirted out of it and onto the mirror in front of him. The salty substance coated his mouth and as he came; he blushed as he realized that he’d truly been turned into a cock, cumming on Theo’s behalf without a second thought.

Worse was that Derek couldn’t deny that he’d loved it. It was such an intense surge of pleasure that he’d felt, easily outweighing any solo session or any sex that he’d ever had. Being a cock was truly the gateway to the ultimate pleasure, Derek fearfully began to realize. 

That epiphany was soon forgotten when Derek stared back into the mirror, shocked to see his thick black hair beginning to recede. It slowly pulled its way back into his scalp until the alpha’s head was smooth. However, he saw that his head was oddly shaped, not looking as round as it should. Instead, there was an odd curvature to it, especially near the bottom that made it look more like a mushroom cap than a head.

Derek’s eyes winded even further when a slight indentation pressed inward at the top of his head, forming a piss slit. The stunned werewolf was helpless to do anything except watch as his mouth closed, his lips fusing shut until it vanished altogether.  His nose shriveled up and disappeared next. Finally, his eyes were next as they closed tightly and fused, yet he was still able to see.

When all was said and done, Derek stared back at a cock. The shaft and head blended in seamlessly, giving absolutely zero indication that it was Derek before. 

Derek couldn’t say anything or beg to be changed back. The only response he could give was twitch, causing Theo’s cock to throb and rocket back to life.

On cue, that glorious surge of pleasure erupted throughout Derek once again. He new head, the perfectly shaped cockhead, oozed precum.

“I’m gonna use you to fuck Stiles’s tight ass,” Theo snickered, wrapping his fingers around Derek’s cock body again.

Immediately, Derek succumbed to the intense pleasure rippling throughout his new body. He instantly gave in, knowing that his new body was built solely for pleasure and sex. He loved being a cock and he looked forward to all of the sexual experiences that he’d get to have.

Day 24: Cow

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

Derek grimaced as he swallowed down the odd tasting protein shake. “That tastes weird,” he spat. “What’s in it?”

Theo shrugged his shoulders. “It’s a new recipe I’m trying out,” he answered, smirking slightly.

The werewolf and the chimera had been trying to work more closely together, for the sake of the two packs in Beacon Hills. As a result, Derek and Theo would try to be more cordial with one another. One such activity that the two pack leaders actually didn’t hate to do together was work out at the gym. There was a sort of playful rivalry that the two engaged in, always trying to out lift the other as they worked out, trying to get more gains.

Being an alpha werewolf, Derek easily out lifted Theo and his muscles were way larger by comparison. The chimera, on the other hand, tended to stick with a more toned physique, not allowing any of his jealousy to show on his smiling face.

Which was why he was all smiles as he offered Derek a drink of his own secret concoction. The mischievous chimera had fought hard to hide his triumphant grin as he’d watched Derek take a hesitant sip of the “protein shake”.

Derek still wiped at his mouth with disgust at the horrible shake that Theo had offered him. “Yeah, I think I’m gonna stick to my usual,” he huffed. “Thanks though.”

Again, Theo shrugged. “Suit yourself,” he happily hummed.

The two men went to starting their workouts, Theo keeping a careful eye on Derek.

Derek, oblivious to the chimera’s staring, went to the chest fly machine, racking up a ton of weight before performing reps. As he worked out, he noticed an odd tingling sensation in his pecs that wasn’t like the normal burn that he’d expected. Instead, this one felt almost electrifying and oddly… good. Really good.

Derek blushed slightly as his chest tingled, his nipples feeling as if they were hardwired directly to his cock. His cock started to stiffen up in his shorts, and as he continued to perform reps, Derek had to hold back a moan.

“Mmmm,” Derek moaned as he tried his best to keep his lips pursed. His blush deepened when he looked over and caught Theo staring.

The alpha werewolf quickly diverted his gaze and tried his best to continue his workout.

Derek was trying so hard to ignore the odd sensations emanating from his pecs that he hadn’t even registered the growing tightness of his shirt until he heard a loud rip echo throughout the nearly empty gym.

He let go of the weights, letting them bang loudly back to the machine. Cocking his eyebrow, Derek looked down at himself, gasping loudly at the large pecs attached to his chest.

“M-my pecs!” Derek stuttered out of shock. “They’re huge!”

Staring downward, Derek’s previously proportional pectorals had been wildly inflated. They jutted out dangerously from his chest, looking round and bulbous. It looked like someone had sliced a soccer ball in two, glueing both halves onto the werewolf’s hairy chest, looking incredibly out of place on his muscular body. Worse for Derek was that his nipples had even enlarged, growing thicker and protruding off of his massive chest like nubby fingers.

Derek blushed when he squirmed in his seat on the machine, feeling how much his chest bounced and jiggled. Oddly, his pecs felt so heavy and cumbersome, and when he moved, he felt an odd sensation of something sloshing deep inside of them.

Theo snickered as he looked the top-heavy alpha up and down. “I’d say so,” he teased. “Those are some serious udders you’ve got there, Derek.”

Derek shoved himself away from the pec fly machine and hurried towards the privacy of the locker room. As he moved, he noticed the arched back stance that he had to take in order to accommodate for his inflated pecs. This caused the enlarged mounds to be thrusted outwards and more into the open, being impossible to conceal. They bounced and jiggled with every step the frantic alpha took, that sloshing sensation growing in fervor.

When he reached the locker room and stared into the mirror, Derek paled at his warped reflection. His pecs and nipples were huge, easily out-shadowing the rest of his impressive musculature, every other body group looking like an afterthought. His jaw dropped, resting upon the cresting pecs that were pushed upwards and out.

Theo, a devilish smirk still plastered on his face, sauntered into the locker room. He crossed his toned arms over his proportional chest as he studied Derek. “They don’t look that bad, Derek,” he snickered. “Maybe we can get you a bra?”

The color gradually returned to Derek’s face as he turned red, slowly putting the pieces together. “You did this to me?” he accused, gesturing down at his massive chest.

“Duh,” Theo scoffed. “I grew tired of always being the small one, so I did some research and found that a really good growth formula contains alpha milk. Hence, all I needed to do was get you to produce some.”

“‘Alpha milk’?” Derek repeated, looking down hesitantly at his large pecs, frowning when he couldn’t anything past their bulbous size.

Theo walked over and didn’t give the alpha any warning before he reached around and grabbed Derek’s meaty pecs.

“Oohhh!” Derek couldn’t help but moan as his muscletits were fondled. Despite his panic and frustration over having his chest altered, he couldn’t ignore the surge of pleasure that rippled through him. In addition to increasing in size, his pectorals also drastically increased in sensitivity. Every touch from the other man’s hands lit up pleasure receptors that Derek had never had before. His knees buckled and his head rolled back as he was felt up. No amount of sex or playing with his cock could ever compare to the brilliant sensations on his chest, and deep down, Derek felt himself craving more.

Theo began to thumb Derek’s nubby nipples, and the werewolf felt as if he’d explode at any second. His heavy pecs lurched and he felt that sloshing inside of them grow even more; and Derek swore that his pectorals began to feel slightly larger.

Derek tensed up, shooting his load. However, instead of cumming, his nubby nipples squirted out a white substance. The pressure in his muscletits subsided the slightest bit, but Derek felt something else bubbling deep within him. He tried to swallow it down, but the alpha werewolf couldn’t help himself.

As his nipples leaked, Derek bellowed out a deep, “Moooo!”

He was so caught up in the feeling of pleasure that left tingles all over his skin, especially his burning nipples, that Derek didn’t even have time to feel humiliated over that fact that he’d mooed like a cow.

Meanwhile, Theo strategically placed his bottle under the alpha’s leaky nipples, collecting the milk that had seeped out. Placing the cap on it, he grinned widely.

“We’ll have to do this more often, Derek,” he happily said. “There’s a lot of guys out there who’d give a fortune for some alpha milk so that their muscles can grow bigger. And just think, it’s all thanks to you and these udders of yours.”

Derek wanted to be angry, to lash out at the chimera for turning his pecs into large muscletits. However, Theo reached out and teasingly flicked a protruding nipple, causing a lustful haze to cloud over Derek’s mind.

“Mooo!” Derek bellowed again, his giant pecs jiggling with want.
