Derek wasn’t in control. He couldn’t help it.

The alpha werewolf had no clue what was happening, but the second he heard his husband, Stiles, walk in the front door after getting off from work, he felt a surge of excitement and utter jubilation. Of course Derek loved this husband and was always happy to see him, but this was to a new extreme— almost inhuman.

“I’m home!” Stiles called out.

At the sound of his husband’s voice, Derek’s heart raced and he dropped the TV remote and felt his body crash down to the floor on all fours. Before Derek could wonder what he was doing, he felt his limbs scamper out of the living room and towards the entryway. Inwardly, he panicked, unable to stop crawling on all fours or even stand up. Whenever he’d try to, he’d fall back down onto hands and knees, forced down like a dog.

The second his panicked eyes landed on Stiles, though, Derek’s trepidation vanished.

“Woof! Woof!” Derek cheerfully barked and he sprinted towards his husband. He rushed forward and managed to stand up on his feet— well, more like he leaned his top half against the smaller man, again, akin to how a dog jumps on their master. Unable to contain his joy at seeing the other man, Derek leaned forward and licked his husband’s face all over like a puppy.

“Derek, what are you…” Stiles trailed off, looking confused as the werewolf licked him. His eyebrows scrunched together, and his brain tried to tell him that something was wrong, that Derek was acting different. But as the excited mandog continued to give him kisses, he brushed the feeling away and couldn’t help but laugh.

At this sound, Derek couldn’t help but bellow out another, “Woof!” He blushed when he felt his bubblebutt jiggle a little as he wiggled his hips to and fro, almost as if he’d had a tail. Worse was that no matter how hard he tried to, he couldn’t seem to stop himself.

“Okay, Derek, down,” Stiles laughed as he gently pushed against the eager man.

Derek put all fours back down again at the command, his blush deepening. He had no idea what was happening, but a part of him hoped that Stiles could figure out a way to help him. He opened his mouth to ask for help.

“Hrrmm, woof!” Derek barked, his eyes widening. “Woof! Woof!” His deep voice sounded the same, but no matter how hard he tried, Derek couldn’t put together a sentence. His words were reduced to barks and yips, making him let out a loud whimper.

Stiles hung up his coat and turned back to the crawling Derek. “Aww,” he frowned exaggeratedly, “what is it, Der? You want some pets?”

Inwardly, Derek bristled at the way his husband was talking to him, as if he were his pet. However, his body perked up and he wiggled his hips even more. “Woof!” he excitedly barked, so into it that his hands lifted off the ground with the movement.

Letting out a chuckle, Stiles leaned down and scratched behind Derek’s ear.

The feeling was incredible and Derek leaned further into it, barely noticing the way his leg shook. The sensation of Stiles’s hands on him was intoxicating, and his canine mind craved more.

Derek flopped over onto the floor and rolled over onto his back, his arms hanging out awkwardly in front of himself as he presented his hairy chest to Stiles. Derek looked up at the other man expectantly, despite inwardly screaming at himself to stop.

“Aww, good boy!” Stiles cooed as he gave Derek a belly rub.

Instantly, Derek felt his cock rocket to life, slipping out of his boxers and bobbing out in the air. He couldn’t believe that he was acting like a dog, getting a belly rub from his husband. But he couldn’t deny that he loved it. Something about the way Stiles’s hands ran over his body was purely orgasmic, and the werewolf craved more. Every hairy crevice of his muscled chest was felt up by Stiles, and when his fingers ran over his hard nipples, Derek was pushed over the edge.

“Arroooo!” he howled as he came, his cum shooting up into the air and landing all over his pecs. He panted as he tried to catch his breath, feeling as if he’d just blown the largest load of his life.

Stiles stood up. “Let me change and then we’ll go for walkies,” he said as he walked up the stairs.

Alone, Derek’s mind finally cleared enough for him to start to freak out over what was happening to him. Gritting his teeth, he tried with all of his strength to stand up or speak, but it was futile. Finally giving up on that, he crawled around the downstairs, shocked to see that the house had changed. There was now a dog bowl in the kitchen with DEREK printed on it in large, blocky letters. Unable to help himself, Derek crawled over to the water bowl next to it and lapped up some water noisily, splashing liquid all over the hardwood floor in the process. He leaned up, his face cherry red at his actions, but his thirst satisfied at least. 

Scampering into the living room, Derek winced at the large dog bed in the corner along with the rubber toy in the shape of a bone.

The mere second Derek’s eyes landed on the toy, his heart began to race and he couldn’t help but rush over and happily take the toy in his mouth. Whenever he tightened his jaw on it, it let out a loud squeak, further exciting the werewolf even more. He happily thrashed his head around, loving the squeaking from his chew toy.

“Ready?” Stiles asked, interrupting his play time as he walked down the stairs in more comfortable clothes.

Derek cocked his head to the side and dropped the toy from his mouth, humiliated beyond belief. He was used to be a boasting and powerful alpha, not some damn puppy! Still, as Stiles grabbed the leash off the rack, Derek scampered forward eagerly.

“Sit,” Stiles said as he held out the black, studded collar. There was a small sliver tag on it that read out: Derek, along with Stiles’s phone number.

Derek immediately sat like a dog and straightened his torso as best as he could. He puffed out his chest muscles with pride, loving the way Stiles looked over him. He was such a good guard dog— no, wait, he didn’t mean that.

Stiles put the collar on Derek and attached the leash, barely having time to open up the door before Derek excitedly bolted out. 

The smell of the fresh air and the sounds of the birds chirping was so much, and Derek couldn’t help but whip his head around to take in all the senses. He loved the bright colors of the cars that zoomed by, and he couldn’t help but preen at how Stiles walked in line with him. Derek’s tongue happily lolled out of his mouth as he walked.

The two of them came to an intersection, and without thinking, Derek sat down and looked upwards at Stiles.

Stiles looked left and right before nodding down at Derek, the werewolf standing back up on all fours and continuing their walk.

“Good boy, Derek!” Stiles cooed. “That’s a such a good boy for waiting to cross the street!”

“Woof! Woof!” Derek happily barked, loving how Stiles praised him. He was such a good boy, especially for Stiles.

“Hey there, Stiles!” a voice enthusiastically echoed out.

Stiles looked away from Derek and then smiled lazily at Theo, who walked towards the two men. “Oh, hi Theo,” Stiles said, in a less cheery voice. This one almost sounded distrustful. 

At the sound of Stiles’s change of tone and the approaching of the other man, Derek couldn’t swallow down the fierce protectiveness that bubbled up in his chest. He stomped forward and puffed out his chest as best as he could, steeling his arms to make his muscles look even bigger.

“Grrr!” Derek growled at the other man, making him stop in his place.

Stiles tightened his grip on the leash and kept Derek back, offering Theo a meek smile. “Sorry, Theo,” he huffed, “Derek’s not great with other people yet. I’m still getting him trained.”

Derek stopped growling, but kept his large werewolf fangs bared threateningly at the other man.

Theo held his hands up and shook his head with a chuckle. “Well, I know you’ll get him trained well soon,” he sighed. “You always said that you wanted a dog…” With that he turned around and walked off, but Derek could’ve sworn that he’d heard him mutter “…I must’ve messed up the spell…”

Stiles and Derek finished their walk, the whole time Derek loving the quality time with his husband. Derek had loved smelling all of the flowers in their neighbors’ yards, he'd enjoyed the way Mrs. Hall ad given him a pat on the head (it’d been nothing like Stiles’s head pats though), and he’d chased a squirrel much to Stiles’s annoyance.

When they returned home, Stiles fed Derek some food, which Derek happily gobbled up. He followed Stiles around the house as he did little chores here and there until it was nighttime. 

“Time for bed, Der,” Stiles yawned, stretching his arms over his head and he sauntered towards the bedroom. He hopped in the bed and lied down.

Derek followed him into the room and spun around a few times before lying down on the dog bed that was at the foot of his bed. There was a rawhide there from earlier, and Derek chomped down, gnawing it with his large teeth. He was so happy. He had the best master in the whole world, he got a belly rub earlier, and he got to have walkies.

It couldn’t get any better than this—

“It’s kinda cold,” Stiles shivered. “You want up, Der?” He patted the mattress.

“Woof! Woof!” Derek excitedly barked as he jumped up onto the bed and scurried over to his Stiles, licking his face lovingly. 

“You’re such a good boy,” Stiles laughed as he scratched behind Derek’s ear.

“Woof!” Derek happily barked, his wide and toothy smile dominating his face.

Day 22: Stripper

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

"You know, Derek,” Isaac scoffed as he trailed behind his alpha in the dimly-lit club, “when I agreed to come to your bachelor party, I didn’t think that we’d be stalking Stiles during his bachelor party.”

Derek just grunted in response, using his werewolf eyes to scan the crowd. His snarl was set deep on his face as he looked for his fiancé, ready to tear some guy who gets too close to him to shreds. In the back of his mind, Derek was already berating Scott for dragging Stiles to a strip club. Granted Stiles and Derek hadn’t explicitly vetoed strippers at their respective bachelor parties, Derek wasn’t good at quashing down his jealous side.

Hence, he’d bribed Isaac with the promise of whiskey and cigars in the guise of a bachelor party, when in reality they were spying on Stiles.

“He’s right over there,” Isaac sighed, gesturing towards a private booth.

Derek narrowed his eyes in that direction, seeing Stiles sitting with Lydia and enjoying copious amounts of alcohol. Stiles had ordered a bright pink one that had an array of colorful fruits on top of the glass, and he eagerly sipped it down as he chatted away with his friends. Even though it was clear that this club was meant to have some dancers, given the pole on top of the table, Derek was slightly relieved when he saw that his fiancé wasn’t anywhere near the strippers.

“Oh,” Derek muttered, feeling a little foolish.

“See?” Isaac said, clapping his alpha on the back. “All that worrying for nothing. Shoot, if you were really that concerned, then why don’t you just be his stripper?” Shaking his head, Isaac stalked over to the table where Stiles’s bachelor party was at, happily snatching a drink off of the table.

Derek rolled his eyes and turned around, getting ready to leave the club.

The music on the speakers changed to an upbeat tempo dance song. The beats were so loud that they took over Derek’s senses, and he struggled to hear anything outside of the wordless song that a bunch of sweaty dancers gyrated to.

He didn’t notice it at first, but Derek soon became altered to the fact that he was slowly starting to shift his hips from side to side. The movement began to pick up speed until the werewolf was gyrating in the club, just like the other dancers.

The alpha’s heart started to race in his chest as he realized that he couldn’t stop. No matter how much he tried to tell himself to stop dancing, Derek was quickly learning that he wasn’t in control of his own body.

Derek’s hips kept swishing back and forth, and the alpha’s trepidation grew when his muscled arms started to undo the buttons on his shirt. Derek popped them off, one by one, until he tossed the useless fabric to the ground. The werewolf was shocked as he threw his hands behind his head, crunching his abs to make them pop as he couldn’t stop showing off on the middle of the dance floor. 

A few of the other patrons looked Derek’s way and even began to cheer him on.

Derek was beyond humiliated and wanted nothing more than to run off and hide from the prying eyes, but the more eyes that were on him, the worse his uncontrollable behavior grew.

Despite roaring with fury on the inside, Derek pursed his lips as he reached up with both of his hands, thumbing his nipples for the crowd. Derek was virtually begging himself to stop, but those pleas were quickly erased when he felt his cock start to harden from showing off. His hands dropped to his pants and before he could try to stop himself, the werewolf tore the denim away.

Clad in only his tight boxer briefs, the frantic Derek could only smile as he gyrated his hips, causing his hard cock to bob noticeably back and forth.

The crowd erupted into a chorus of cheers as Derek was egged on.

Derek straightened up and held his head up high, his stiff legs carrying himself off the dance floor and over towards the table where Stiles sat at. Despite the cocky smirk on Derek’s handsome face, his eyes were wide and panicked, and he hoped that his fiancé would figure out a way to help him.

“I heard someone’s about to get married,” Derek said in his deep voice, crossing his thick arms over his beefy chest.

Stiles looked up from his drink, his eyes going wide at the side of the nearly naked Derek. Coughing on his cocktail, all he could do was nod.

Lydia was the only one who seemed to have her wits about her. “Derek?” she snorted. “Why are you crashing—”

Derek stepped in front of her to approach Stiles directly, smiling widely despite his freaked out eyes betraying his cocky expression.

“Well,” Derek heard himself say, “I hope your future husband can take care of all your needs.” He felt himself turn around and flex his meaty bubblebutt. He playfully bent over, wiggling his perky butt for his fiancé, feeling cool air pass over his cheeks more than it should have. Derek looked down at his crotch, inwardly wincing at how his boxer briefs had somehow morphed into a tight, black thong. The pouch was filled to bursting with his massive cock, and suddenly, he could feel the small strap of fabric slipping between his huge cheeks, allowing his bubblebutt to be on full display. To add to it, cuffs appeared on his wrists while a collar and bowtie magically popped around his neck. Derek cringed at his new, slutty outfit, but his body only fed into it.

Derek turned back around and flexed his large biceps in front of Stiles’s awed face, briefly leaning down to lick his massive mounds. His pecs bounced up and down, and Derek grabbed the back of Stiles’s head, pulling it forward so that his face was shoved into the crevice of Derek’s impressive pectorals. Despite being extremely embarrassed by his actions, Derek couldn’t deny that he was also turned off by showing off for his fiancé.

Erica drunkenly tossed a few dollars at Derek’s feet, and Derek felt himself up the ante.

His thumbs hooked into the thin straps of his thong and he quickly tugged the skimpy fabric down, allowing his hard seven inches to bob out in the open air for everyone to see.

Derek was screaming on the inside, but all he could do was helplessly smile and wrap his fingers around his thick cock. He moaned loudly as he began to jerk himself off in front of Stiles, a growing crowd forming behind him to watch the show. When he thought that things couldn’t get any worse, Derek dropped to his knees and eagerly buried his face in Stiles’s covered crotch.

Stiles immediately grew hard, and despite having about a billion questions regarding way Derek was acting the way he was, he couldn’t help but give in. He unzipped his pants and allowed his slutty fiancé to fish his cock out.

Derek felt himself lean in and take all of Stiles’s cock into his mouth hungrily. He couldn’t prevent his loud moans from thundering out from himself as he sucked off his fiancé. Derek wasn’t used to being the one giving a blowjob, but he was somehow able to deep throat the entirety of Stiles’s cock, even pausing a bit to lap at his slit. Worse was that he couldn’t stop himself from flexing his muscles and wiggling his huge muscle butt, the squishy globes jiggling wildly behind him for the crowd to gawk at.

No matter how humiliated Derek felt, he couldn’t ignore how great it felt to suck off his fiancé— plus, it was even more amazing for having others to cheer for him. 

Stiles tensed up and came, shooting his hot load straight down Derek’s throat. The werewolf greedily guzzled it down, moaning loudly as he did so.

Derek felt all of the large muscles in his body flex and bulge as he came, shuddering as he unleashed his load all over the floor of the club. He moaned loudly as he came, made all the more worse but he fact that the whole crowd cheered him on as he came. As he panted in his post-orgasm, Derek finally felt his blush take over his face, being back in control of his body again.

“Damn, Der,” Stiles breathed as he tried to catch his breath, “you’re the best stripper I’ve ever seen.”

Despite himself, Derek felt himself grow hard again and he couldn’t help but smirk upwards at his future husband. “Well, lucky for you I have lots of moves I can try out on you,” he said, surprised that he meant it.

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.

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 27: Hot Cop

“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 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.
