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 30: Daddy

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19 │ 20 │ 21 │ 22 │ 23 │ 24 │ 25 │ 26 │ 27 │ 28 │ 29 │ 30

Derek didn’t like being called “Daddy”.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

And he loved it.

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

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

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

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

Day 11: Pup

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11

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 20: Jock

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

Derek sighed as he walked into his bedroom for the night, feeling incredibly drained from his argument with Eli. “I just don’t get it,” he huffed, throwing himself down onto the bed in a huff. “No matter what, we just can’t seem to see eye to eye.”

Stiles frowned and ran a caring hand over his husband’s chest. “He’s a jock,” he said. “All his high speed brain can focus on it sports.”

Derek frowned deeply. “I guess,” he growled. “I just wish that I could understand him better. Like, as if we were on the same wavelength.”

Derek lied back and rested next to Stiles, having trouble sleeping due to his fight with his son. He and Eli had been fighting with one another lately, usually due to typically father-son issues, such as Eli letting his grades slip due to his intense interest in sports, which tended to lead to Derek threatening to pull Eli from whatever team he was on that month. His son was a total jock, something that Derek didn’t really experience while in school.

As Derek drifted off to sleep, he felt his limbs tingle, his mind constantly wishing that he could understand the jock better…

The alarm blared, and Stiles sleepily slapped it silent.

Derek stretched his muscled arms above his head, yawning loudly as he woke up. As he moved, his face scrunched up as the stench of musk and sweat hit his nose, emanating in waves from his hairy pits.

Even Stiles could smell it with his dulled human senses, jerking back and plugging up his nose. “Damn Der,” he gasped, “no offense, but you reek.”

Derek felt his face grow warmer as he blushed. “Yeah, Bro,” he heard himself balk in his deep voice, “I must’ve worked up a big sweat last night.” Derek was puzzled over how deep and slow his voice sounded, and the way he’d called this husband “Bro”.

For a brief moment, Stiles scrunched up his brow in confusion, but it smoothed out rapidly as a small grin formed on his face. “Typical jock,” he lightheartedly laughed, slowly getting out of the bed to get ready for work.

Jock? Derek puzzled over what Stiles had said as he got out of bed, his body automatically lumbering towards the dresser. He yanked open the top drawer and paused as he was greeted with an array of jockstraps— his boxers nowhere to be seen.

As if his body had a mind of its own, Derek felt his muscled arms move and snatch up a jockstrap. He yanked the small garment on, the pouch filled to the limit with his massive cock and balls while his perky ass bubbled out the back.

“Don’t you want to take a shower?” Stiles asked, the tone in his voice indication that he’d hoped that Derek would listen to him. 

“Nope,” Derek heard himself scoff, answering without any thought of his own. He even leaned down and sniffed at one of his stinky pits, the musky stench filling the confines of the bedroom. “I’ll be fine. Besides, I’m gonna get all sweaty at practice anyways. So what’s the point?”

Practice?

Derek was so caught up in his odd behavior that he’d barely noticed when he’d opened up another dresser drawer, grabbing a football jersey. He yanked the tight garnet on, noting how his muscles pressed against it, illustrating his athletic prowess. Next, he grabbed some small workout shorts that only came up to mid-thigh and were so tight that his butt and package pressed noticeably against it, almost as if they were on full display.

When he looked at himself in the mirror, Derek inwardly winced at the dim smile on his face. He still looked the same, with his mature and masculine beard that had flecks of gray in it; however, he felt ridiculous being dressed up like a total jock, feeling childish.

His body evidently wouldn’t let any of his inner turmoil show as he lifted up a buff arm, flexing a large bicep. “Damn,” he heard himself say, “I’m getting fuckin’ huge, Bro!”

Despite himself, as Derek flexed in the mirror, he felt his cock start to stiffen within the confines of his tight jockstrap. The pouch tented outwards as it struggled to maintain his meaty cock, looking as if the werewolf was smuggling a summer sausage in his pants. Instead of blushing or trying to conceal his package, Derek felt himself place this hands on his hips and shove his crotch forward expectantly.

“Hey, Bro,” he said, “I’m so fuckin’ horny. Wanna help me out?”

Stiles smiled at his husband, chuckling as he shifted off the bed. “Damn, Der,” he laughed, “that thing’s always cocked and loaded.”

Always cocked and loaded? Derek’s eyebrows rose as new memories filtered into his foggy head, being filled to the brim with Derek being hard and rutting against whatever crossed his path. The stud was always incredibly horny, his cock seemingly rocketing straight to attention after a few moments after cumming. He wanted to blush at the image of himself sauntering down the street in his tight jerseys, his hard cock pressed tightly against his thick thigh for all to see.

Derek’s frantic thoughts slowed down significantly as his husband dropped to his knees in front of him, wasting no time in taking in his full member.

“Oooh!” Derek loudly bellowed, his deeper sounding voice bouncing off the thin walls in the house. “Yeah, suck that cock, Bro. Bet it’s the biggest ya ever had!” The normally silent werewolf couldn’t keep his mouth shut as he was sucked off, moaning loudly and cockily bragging about his cock. No matter how humiliated the alpha was over his uncontrollable behavior, he couldn’t help but bask in the warmth of pleasure that washed over him. All of his panic was momentarily forgotten until all of his ample muscles tensed up. “Uunghh!”

Derek cried out as he came, shooting what felt like the biggest load of his life. He was left spent and trying to catch his breath as Stiles stood up and went about getting ready for his day at work.

“Thanks, Bro,” Derek heard himself say. “I gotcha next time!” Already, at the mere suggestion of sucking off his husband, Derek’s cock plumped up and it took him a few moments to realize that he’d been absentmindedly fondling his hard bulge after tucking it back into his jockstrap.

As the werewolf continued with his morning routine that didn’t involve a shower, he couldn’t help but wince whenever he lifted his arms and his musky stench would waft out from his pits, smelling as if he’d just finished a killer workout at a crowded gym.

Derek walked downstairs and paused at the front door where Stiles gave him a quick kiss. “Can’t forget this, Coach,” Stiles said, handing Derek a silver whistle attached to a small chain necklace.

Derek was confused over both the whistle and why Stiles had called him “Coach” for some reason. However, the confusion quickly vanished when Derek realized that he no longer worked at his auto shop but was instead a coach at Beacon Hills High School. His stomach dropped when he tried to recall the massive amounts of paperwork that were supposed to be waiting for him on his desk at the shop, all of them detailing receipts and parts on orders; yet, now the werewolf’s muddled brain struggled to comprehend what all of those numbers meant. He paled even further when his knowledge of business management wasn’t the only thing gone. In a panic, Derek’s eyes darted around the house and sure enough, simple items seemed to be way beyond his mental grasp. For example, although he’d used it hundreds of times before whatever the hell happened to him, Derek stared at the coffee maker that was in the kitchen, unsure what all of the buttons meant… luckily Stiles was there to help him out since he was such a dumb jock.

Derek inwardly flinched at that last thought, recalling the stupid wish he’d made last night. He’d wished that he could understand jocks more.

Now Derek was a dumb, horny jock.

His days were filled with nothing except working out, playing sports, and fucking. That’s all a dumb jock like him was good for.

Still, Derek put the whistle around his neck and puffed out his large pecs against his tight spots jersey. “Thanks, bro,” he dimly smiled before leaning forward to rut his hard cock against Stiles’s thigh. “You gonna come during my lunch break to help me out with this?”

“Of course,” Stiles said, resting an admiring hand on Derek’s bicep, which the werewolf flexed out of instinct, “I can’t have my big jock going too long without any release. Poor guy would be all pent up.” He mock frowned, a hint of playful condescension audible.

Derek’s foggy mind didn’t pick up on it, and instead he just smiled back widely. “Yeah, Bro,” he agreed in his deep voice, “if I don’t cum at least five times a day, I can’t think well.” He paused at the odd words leaving his mouth, but then the alarm on his phone went off and he perked up. “Oh shit. I’m gonna be late! Love ya, Bro!” He kissed Stiles on the cheek before hurrying out of the house and lumbering towards his Camaro, his hard cock tenting out his tight shorts.

Day 19: Action Figure

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

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

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

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

Unfortunately, Derek was having no luck.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Theo snapped his fingers.

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

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

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

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

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

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

31 Days of Derek Hale

Day 23: Ghost Possession

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

Despite being a werewolf, Derek didn’t believe in ghosts. In his opinion, they were the cheap product of Hollywood trying to advertise uncreative horror films. He would scoff at the young adults who’d dared one another to sneak into McFadden Manor, only to hear them swear up and down that they’d seen a ghost. Lies, Derek figured.

Still, when Stiles had made up his mind to investigate the ghost stories surrounding McFadden Manor for Halloween, Derek had instantly jumped at the chance to tag along in an attempt to look brave and woo the hyperactive human. 

Unfortunately, Derek couldn’t hide the grimace as he walked through the deserted McFadden Manor. The abandoned mansion was the center of numerous spooky, Halloween-themed tales— all of them focusing on a mischievous trio of ghosts who liked to mess with unsuspecting people. The wide smile on Stiles’s face deeply contrasted with Derek’s scowl.

He eagerly held up an ancient-looking camera. “We should split up and cover more ground,” he said. “I’ll go down towards the garden while you inspect the bedrooms. Radio me if you see anything.” He shoved a large, dinosaur era walkie talkie towards the werewolf.

“I can just text you…” Derek muttered, studying the heavy tech in his hands.

“Thanks for coming with me again, Der,” Stiles said, offering the usually grumpy werewolf a sincere smile, making the alpha’s heart flutter in his chest.

In response, Derek puffed out his muscular chest with pride, his pecs pressing teasingly against his thin, white t-shirt. “S’no problem,” he grunted, trying to play it cool, but he could feel his cheeks grow hot as he blushed. Plus, he couldn’t help but crunch his stomach to make his abs pop against his shirt too, his muscular bod being his best form of flirting since he wasn’t really good at wooing orally.

Stiles happily ran down one of the dark hallways towards his destination, Derek not-so-subtly watching his perky butt as it disappeared.

“Damn,” Derek admired before frowning at the sight of the decrepit mansion. “Damn it.”

Frowning again, he shrugged his broad shoulders and lumbered throughout the dark, cobweb-filled halls. To humor himself, Derek sniffed at the air, smelling nothing in the air except for dust and rats. He rolled his eyes at himself participating in this foolish activity, yet, he forced himself to focus on the endgame: Stiles and him getting together… and then heatedly fucking in his Camaro.

That last thought put a little more pep in Derek’s steps as he explored the empty rooms in the mansion.

*Thud!

Derek tensed up at the sound that echoed out from one of the bedrooms. Following the source, Derek entered a room near the end of the hallway. The room turned out to be a bathroom, the rusty toilet giving it away. There was a dust-covered sink with a dirty mirror near the entryway, and in the far end was a standing tub with a yellow curtain closed over it.

Derek cocked his eyebrow in confusion over the fact that the water seemed to be running in the tub, steam even billowing out from the curtain.

“What the hell?” Derek wondered aloud, knowing that there was no way this house was occupied given its dilapidated state. Still, the running water left the werewolf deeply confused. He grabbed the edge of the shower curtain and ripped it to the side.

Inside of the tub was a portly bluish figure that was slightly transparent. Looking like a caricature ripped out of a cartoon, the ghost had a little tail that seemingly phased in and out of existence as the creature showered. When it noticed that it was being watched, the ghostly figure looked over at Derek and gasped, covering its lower half with its hands… despite there being really nothing to see.

“Do you mind?” the ghost scoffed.

Derek was stunned silent for a moment, his eyes wide as he stared at an actual ghost that was floating before him. “Holy shit,” he finally breathed. “You’re a fuckin’ ghost!”

The ghost exaggeratedly rolled its eyes at Derek. “No shit,” it huffed in a baritone-filled voice that only emphasized its rotund girth. A sly grin formed on its translucent face and its eyes sparkled. “You know, most fleshies tend to avoid this place because of me and my brothers, but here you are.” He sniffed at the air, his smile growing wider. “A werewolf?”

Derek flinched and took a cautious step back.

The ghost continued. “We don’t get a lot of your kind here,” he chuckled. “Your bodies tend to be a little more sturdy. This should be fun!”

The ghost lurched forward at lightening speed, much faster than Derek’s werewolf instincts could react. Since his jaw was still hanging low in shock, the ghost aimed right for the alpha’s agape mouth. 

Derek felt his mouth being stretched to the limit as the ghost squeezed himself inside of him. It was a difficult sensation to describe. Thanks to the ghost’s vapor-like body, it felt as if there was a gust of air that was keeping Derek’s jaw thrusted down as it shoved itself in. Cartoonish stretching noises, like rubber, sounded out as the ghost entered the werewolf. Derek felt himself getting fuller and fuller, feeling as if he’d just eaten a multi-course meal and was stuffed to the brim.

With a simple pop, the ghost finished his entrance and successfully squeezed his rotund body deep inside of Derek.

The werewolf felt full, his stomach and even lower end of his throat feeling as if there was a thick soup trapped in it. Derek stumbled around on shaky feet, trying to piece together what had just happened. The ghost squirmed a little as he settled in under Derek’s skin, the werewolf wincing at the sensation. 

“Damn, I can’t believe that worked!” Derek heard himself exclaim. “I usually have trouble fitting inside tiny bodies.”

Tiny? Derek balked.

Derek’s tingling limbs appeared out of his control, and the more Derek tried his best to strain and walk on his own accord, the more horrified the werewolf grew as it dawned on him that he wasn’t in control of his body. He even attempted to open up his mouth and demand that the ghost leave his body, but he couldn’t even do that— instead, Derek was more so a passenger inside of his own body. He could still experience every sense, smelling and feeling everything around himself, but he couldn’t move or speak on his own.

He felt his legs propel him forward, turning around to look into the mirror. Derek bristled at his own reflection which only smiled back at him, his smile eerily similar to that of the ghost’s.

What the fuck are you doing to me?! Derek roared on the inside. Get the fuck out!

The ghost only shook Derek’s head mockingly. “No way,” he said, making Derek’s body and voice say it on his behalf. “I kinda miss having a body so I’m gonna hang onto yours for a bit. The name’s Fatso, by the way.”

That’s a stupid name.

The ghost shrugged. “And this is a stupid body,” he countered, exploring Derek’s body, running his hands over it. Derek could feel every touch, unable to stop feeling himself up. “There’s barely any room inside of here. Let’s fix that.”

Derek screamed on the inside as he witnessed his stomach shudder before it expanded outwards. His gut grew in size and it rounded out as Fatso forced it to bubble out. Derek’s chiseled abs disappeared as a thick layer of fat appeared over them, going from firm to large and jiggly. It grew bigger and bigger, becoming huge and bulbous as it jutted far out in front of Derek, looking as if he’d swallowed a yoga ball instead of a ghost. To add to the inflation, even Derek’s pecs packed on some fat. They lost some of their tone as they grew larger and saggier, resting atop his enormous belly. There was still some traces of Derek’s large muscles underneath his new girth, but instead of looking like he lived in a gym, he looked more like some ex-jock who was in the middle of a perpetual bulking phase.

What the fuck did you do to me?! Derek roared on the inside, wincing as he examined his new body in the mirror. He must’ve gained well over fifty pounds, with most of it centered on his new gut. His mysterious growth had torn his t-shirt to shreds, forcing him to see all of his girth at once. Despite looking hard and solid, Derek winced at the way his gut hung over his jeans, sagging slightly.

Fatso mock-frowned. “Don’t be like that,” he taunted, putting both of his hands on the sides of Derek’s new belly and giving it a playful shake, causing it to bounce wildly. “I think you look much better with some more meat on our bones. Now there’s some food in the kitchen that we can eat.”

Eat? You mean you want me to get even fatter? Derek protested, unable to prevent his body from waddling out of the bathroom and down the hallway. His thicker thighs rolled over one another as he moved, and his rotund belly stuck so far out in front of himself that he couldn’t even see his feet. He inwardly flinched every time his foot thudded against the hardwood floor, sending a ripple through his belly and pecs.

Fatso forced Derek into the kitchen, where he made him lumber towards the fridge. Derek was surprised that when it opened, it was stocked full of food that looked like it’d just been bought earlier that day as opposed to sitting for years untouched.

Derek felt his arms lurch forward, grabbing fistfuls of various treats and snacks. 

“The only downside to being a ghost is that you can’t eat a lot of food,” Fatso lamented. “But the good thing about possessing a werewolf fleshie is that you can gorge on tons and tons of junk food. Much, much more than a human can!”

No! Wait! Derek pleaded.

His pleas fell on deaf ears as Fatso eagerly shoved loads of food into Derek’s mouth, moaning loudly as he tasted all sorts of flavors. Salty, sweet, savory— all kinds of different foods were shoved down Derek’s eager throat, none of them low-calorie.

The entire time, the werewolf inwardly begged Fatso to stop gorging on so much junk food. However, the ghost was paying no attention to him, moaning loudly as he devoured everything in the fridge.

In the center of the fridge was a delicious looking, three-tiered cake with bright pink frosting. Derek could feel his mouth salivating as his eyes honed in on the monstrous dessert. 

Before Derek could uselessly plead with Fatso again, his hands grabbed at the cake as he greedily gobbled it down. All he could taste was the sugary frosting and the chocolate center of the cake, grimacing at the sweetness, yet Fatso loved it.

Derek inwardly froze when he felt something horrible: his pants felt like they were getting tighter.

It was hard to tell since Fatso controlled his line of sight, but Derek could barely make out his gut growing more and more into his field of vision. It didn’t take long for the werewolf to put two and two together to figure out that, thanks to Fatso’s overeating, he was getting even bigger.

His big belly was starting to jut even further away from his torso as it packed on even more size from the delectable cake. His pecs felt heavier as they grew in size, his nipples even stretching out from the sheer expanse of his enlarged chest. Love handles formed and drooped slightly over the edges of Derek’s pants, which felt painfully tight by now.

Pop!

The button on Derek’s pants finally gave out, ricocheting off and landing on the floor. Derek felt a sense of relief as he continued to fill out, his ass puffing out as his cheeks ballooned out and became large and squishy. To account for his larger rear, Derek could even feel his thighs starting to push closer together as they blew up. As Fatso continued to eat, Derek’s body went from bulky to chunky linebacker status, looking incredibly large as if two of him were shoved together into one body.

Fatso fit the last few bits of the cake into his mouth, swallowing it down loudly and straightening back up. He patted his large gut, satisfied, before letting out a loud burp.

“I always gotta get a big cake before every Halloween thanks to silly guys like you who want to come play detective,” he smiled, rubbing his hand up and down his distended belly. “This was nice. See ya next year?”

Derek let out another loud belch, this one accompanied by a flash of blue as Fatso left his body to fly somewhere else in the manor.

Finally in control of his body, Derek gasped loudly as he ran his shaky hands all over his enlarged form. For some strange reason, even with Fatso gone, Derek was left with his added weight, looking massive and round. He took an awkward step forward, blushing as his entire body seemed to jiggle. He couldn’t see anything past his large belly which definitely wouldn’t fit in any of his clothes anymore.

“Damn it,” Derek huffed, giving his gut a tentative poke. “I have to do so many crunches to get this down to size…” He trailed off when his stomach growled, a deep hunger taking over him.

“Hey, Der,” Stiles called out, his footsteps approaching, “still no sign of any ghosts. I’m starting to think that they’re just stories.” Stiles froze when he reached the kitchen, his eyes nearly falling out of his head at the sight of the fatter Derek.

“Um,” Derek blushed, scratching the back of his head nervously, “I think I found a ghost—” He paused when Stiles stepped forward and placed a soft hand on his rotund belly, rubbing it up and down.

A smile forming on his face, Stiles couldn’t help but look up at the large werewolf. “Do you like belly rubs?” he asked, playfully rubbing Derek’s gut.

Although he couldn’t see it thanks to his big gut blocking his view, Derek could feel his cock rocket to attention, already oozing as Stiles gave him a belly rub. “Y-yeah,” he breathed. He blushed again as his stomach growled a second time.

“Big boy’s hungry?” Stiles teased.

Derek just eagerly nodded, looking forward to eating cake and getting more belly rubs from Stiles. 

All in all, it turned out to be the best Halloween of Derek’s life.
