Derek Hale sat in the corner of the bar, brooding over life in general. The sourwolf had a deep frown set onto his face, scowling at nothing specifically— his foul mood creating a dark aura about him.

He finished his whiskey on the rocks and was about to ask for another one, when the bartender (some peppy guy with dyed blue hair) set down a large glass of beer in front of him. The golden drink must’ve been extra-carbonated because tons of tiny bubbles floated around like crazy in it.

Derek cocked his eyebrow up at the bartender. “I didn’t—”

“It’s on the house,” the bartender interrupted him. “It’s a new brand called ‘Bubbly Beer’.”

“‘Bubbly Beer’?” Derek repeated incredulously, almost scoffing at the stupid sounding name. The tough alpha wouldn’t be caught dead drinking such a ridiculous drink. 

Still, free was free.

Shrugging his shoulders, Derek brought the glass to his lips and took a tentative sip of the bubble-filled beer. It was sickeningly sweet and the carbonation made the drink more akin to soda than actual beer.

Derek grimaced at the drink, nearly gagging. He hated sweets.

However, the alcohol content must’ve been high, because after that singular sip of beer, Derek could already feel a slight buzz. His brain felt a little foggy and it actually seemed to dull his angst.

“Meh,” he hummed. “Does the trick, I guess.”

Derek took another sip.

The fog settled in deeper, and a dazed grin formed on Derek’s face. He leaned back further into his chair, unaware of the knowing smirk from the bartender. He struggled to think back to what was bothering him in the first place.

He happily brought the glass back up to his lips, but this time he took a couple gulps of the beer.

Derek’s smile grew a little larger, but it almost subsided when he started to feel a little warm. Like a sudden total wave of heat crashing upon him, Derek suddenly felt incredibly uncomfortable. His white button down shirt was suddenly a bit too thick for his liking, and having it buttoned up all the way made him feel awkward, almost like he was wearing a large tent. 

In an attempt to gain some sort of ease, Derek reached up and undid the top four buttons of his shirt.

“That’s soooooo much better,” he sighed, his goofy grin coming back full force once he wasn’t completely covered. His toned pecs were slightly exposed to the cool air of the bar.

Derek took a few more gulps of the beer.

The legs of the chair groaned loudly as Derek squirmed around. His chest felt heavier and his arms kept colliding with his sides in a way that they hadn’t before… right?

Derek’s heart raced in his beefy chest for a moment, but he quickly shrugged his anxiety away as he glanced down at his meaty muscletits. His massive pecs were barely covered by the button down shirt that they strained against, his nubby nipples poking teasingly against the fabric. His large biceps bulged out of his straining sleeves, constantly bumping against pecs and lats, hindering each one of Derek’s movements. And lastly, the werewolf rocked back and forth on his humongous bubblebutt that strained his jeans to bursting, the big ass making it look like Derek was sitting on a bunch of cushions.

Derek caught a nerdy guy sneak a peek at him from across the bar, and he couldn’t resist lifting one of his big arms to flex a powerful bicep.

The nerd’s jaw dropped, yet he quickly recomposed himself and stood up, slowly heading over towards Derek.

Derek finished off the last of the bubbly beer, setting the empty glass onto the bar.

“Um, h-hey,” the small nerdy guy smiled at Derek. “What brings you here all alone?”

Derek smiled back full force at the other guy, his cock rocketing to life. The ten inch monster snaked down his pant leg noticeably, looking like he was stuffing a summer sausage down his pants.

“Oh y’know,” Derek chirped back, “I’m just, like, totally out here looking for cute guys!” He giggled at the end of his statement, biting down on his lower lip as he ran his eyes up and down hungrily over the nerd’s body.

The nerd smiled back nervously, nearly drooling over Derek’s bulbous muscletits. “Well,” he said, “I’m about to ditch this place, if you wanna come with?”

“Sure!” Derek quickly said, practically hopping out of his chair. He snatched a tight hold of the smaller guy’s hand and began to walk towards the exit.

Derek paused for a brief second, feeling as if something was wrong. His gait was thrown off by the constant jiggling of his bubblebutt behind him, and he had to arch his back slightly to account for his huge pecs. Plus, his head felt so slow.

And he was so painfully horny! 

Despite himself, all he seemed to be able to focus on was cock and getting his big butt stuffed full with the nerd’s. His lust took over and that foggy sensation clouded over his brain again, effectively silencing that alarm bell. 

“Like, this is totally gonna be the best night ever!” Derek cheered as he wiggled his hips, causing his big butt to bounce wildly, loving the lustful look in the nerd’s eyes.

Day 27: Hot Cop

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

“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!”

Day 08: Cock TF

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Day 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.

31 Days of Derek Hale

Day 21: Centaur

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

“R-really?” Derek asked incredulously.

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

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

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

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

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.
