Day 20: Jock

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 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 18: Cockgrowth

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

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

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

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

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

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

“That’s not what I asked…”

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

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

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

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

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

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

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

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

But then it kept growing.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Day 09: Merge

“You’re the worst alpha I’ve ever had!” Peter yelled, throwing his hands up in the air dramatically.

Derek snarled in response, baring his massive werewolf fangs. “I wouldn’t have to be so hard on you if you weren’t so damn stupid!” he countered.

The two werewolves continued to argue and yell at each other, their bellowing voices echoing throughout the house and making peace nearly impossible. 

Meanwhile, Stiles rubbed at his temples in irritation as he tried to read some articles for his college classes, irked that he couldn’t get any studying done with the werewolves’ dick measuring contest going on in the background. Worse was that ever since Peter miraculously came back from the dead, he and Derek seemed to be at each other’s throats constantly.

“You’re the most selfish member of the pack!” Derek growled, puffing out his chest as he tried to threaten the older werewolf. “I should’ve kicked your ass out a long time ago!”

Peter, being the drama queen that he was, rolled his eyes exaggeratedly. “Oh please, Pup,” he spat. “You have no clue what the hell you’re doing. Shit, your little pack would fall apart if it wasn’t for my help.”

The two men kept yelling at each other, ruining any semblance of tranquility as they puffed out their chests in what could be described as a “Bro Off”. Both of them would bark and yell, yet neither one of them dared to throw the first punch.

Finally, Stiles slammed his book shut, over their childish behavior. “Will both of you shut the fuck up?!” he cried.

Derek and Peter both froze to stare at him in bewilderment.

“He started it,” Derek muttered, gesturing at Peter heatedly.

“I don’t care who started it!” Stiles exclaimed. “We’re all in the same pack, so if the two of you could figure out a way to be closer, that’d be perfect!”

As soon as the words left Stiles’s full lips, an electric quality appeared in the air, making the hairs on the werewolves’ arms stand at attention. Before anyone could ask what was going on, Derek and Peter felt themselves moving towards one another, their limbs acting on their own accord.

Against their will, Derek and Peter both raised their arms and seemingly embraced one another in a hug, the two of them wearing worried expressions on their handsome faces as they desperately tried to regain control of their bodies. Even Stiles was shocked, his jaw hanging low as he watched the two werewolves hug one another.

Then something else happened.

Derek was the taller one, and it seemed as if Peter’s smaller (yet still muscled) body melted into Derek’s larger one. As the werewolves merged together, their muscles appeared to combine, becoming larger and much more defined. Their arms combined, becoming larger with much bigger biceps than before. Pecs protruded out in front of their bodies, capped by large, nubby nipples that were twice the size of their respective ones. Even their clothes seemed to merge together, taking Peter’s blue button down and Derek’s white tank, morphing them into a blue and white muscle tank top that served to show off their large muscles.

Derek and Peter were stunned silent as their heads positioned themselves upon broadened shoulders, sitting side by side.

When the changes finally ceased, standing where the two werewolves previously argued with one another, was a two-headed muscle beast. Derek and Peter stared in shock and horror as they used the buff arm that they could control to feel around their shared body, blushing when they could feel the exact same sensations.

“Wh-what happened to us?!” Derek panicked, taking an awkward step forward as if he could pull himself away from his shared body. All that served to do was make his new body stumble, Peter in control of the other leg.

Even Stiles was stunned silent, unable to wrap his head around what was happening. Moments before, Derek and Peter had been arguing, and then they were sharing a body that was twice the size of their normal ones.

Peter felt around his shared body in disbelief, bristling when he noted the obscene size of his enlarged muscles. “H-how did this happen?!” he gasped, unable to wrap his head around the fact that he and his nephew shared an over-muscled body.

Stiles shook his head in disbelief. “All I meant for you two to be closer, not this!” he hurriedly cried. 

The two-headed werewolf struggled to stalk forward, each one of them using the leg that they controlled.

“You better figure out a way to fix this!” Derek growled. “How the fuck can I be expected to perform my alpha duties with this dumbass attached to me? And how can I be expected to be with my boyfriend when I’m sharing a body…” He trailed off when his thoughts were clouded over with Peter’s.

Derek turned his head to glare at Peter’s, who attempted to look away, but given their unwanted proximity, the attempt was moot.

“Really?”  Derek growled, anger bubbling up in his gut.

Peter blushed, but tried his hardest to look unbothered. “He’s kinda cute,” he muttered under his breath, referencing his secret crush on Stiles, which Derek could pick up on thanks to their shared body.

Both of the werewolves flinched when they felt a throbbing in their pants. They each used the arm they controlled to yank down their pants, revealing the twin cocks that they possessed. Both of the impressive members stood at perfect attention, directed straight towards the shocked human.

Derek and Peter sniffed at the air, surprised at the heat radiating off of Stiles.

“Really?” they both asked in unison, shocked at the fact that Stiles seemed to be turned on. 

Stiles shrugged cheekily. “Well, I love Derek, but I also think that Peter is hot, in a weird sorta way,” he admitted, blushing.

Derek and Peter sighed, their shared shoulders rising and falling with the action.

Derek used his arm to scratch at the back of his head. “Well,” he mumbled, “I guess we could try to make this work…”

Peter looked downward at the two cocks that were attached to his and Derek’s shared body. “I hope that Stiles can take two at a time,” he said.

Stiles eagerly nodded. “I can look up some stretches!” he rushed, already looking forward to getting fucked by his new two-headed boyfriend.

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.

31 Days of Derek Hale

Day 26: Twink

Derek bumped into some small, tiny guy. The little guy wore comically oversized clothes as he ran off, looking panicked and frightened. 

“Fuckin’ weirdo,” Derek snorted, readjusting his gym bag over his broad shoulder. 

The 6’3” alpha sauntered into the gym to workout. Normally, the muscled stud preferred to lift or perform bodyweight exercises at home where he wouldn’t have to deal with a lot of people. However, after renovating his house, he didn’t want to mess it up with his musk, so he’d opted to get a gym membership. After a few weeks of working out at one of the local gyms, Derek was surprised to discover that he actually liked to work out in public. There was something about being one of the bigger guys at the gyms that filled him with a sense of pride. Towering over the other men and easily out-muscling them only cemented his role as an alpha, and Derek could only smirk as he threw his weight around the gym.

After changing in the locker room, Derek strutted out onto the gym floor clad in only tight gym shorts that strained against his powerful thighs. His impressive chest muscles were on full display as he moved towards the weight pile. His chiseled, plump pecs illustrated sheer masculine power, and Derek frowned a bit when he realized that the gym was virtually empty.

“Guess the other guys just can’t keep up,” he hummed to himself, grabbing the heavier weights on the rack and performing bicep curls like it was second nature to him. His bowling ball-sized mounds flexed with power as he lifted, and Derek couldn’t help but admire his bulky form in the large mirror.

Derek was so caught up in working out that he barely noticed when another gym patron walked up to the weight pile, grabbing a weight that was a little heavier than Derek’s.

This other guy rivaled Derek’s size, both in height and musculature, much to the alpha’s annoyance. This other guy’s thick curly hair reached the same exact 6’3” height as did Derek; that fact bothering Derek for some inane reason. Plus, this other guy also worked out shirtless, showing off his pumped up muscles that exuded manly power. His chiseled pecs were just as rounded as Derek’s, and when he lifted his weight, his bicep bulged to the same exact size Derek’s had.

The other guy glanced towards Derek and nodded at the lighter weight in his grasp. “My girlfriend likes to use the smaller weights too,” he chuckled.

Derek bristled at the obvious attempt to make him look weaker than the unknown douchebag. He just clenched his jaw as he set the weight down, opting for an even larger one than the other guy’s. Gritting his teeth, he began to rack out several bicep curls.

The subtle way the other man’s eyes widened caused the alpha to smirk, loving how his bicep pumped up to an incredible size. The arm burned with lactate and he could vaguely make out the other guy muttering something under his breath, yet Derek was too focused on trying to look like the bigger man.

Derek’s muscles burned from his workout, the burning sensation seemingly spreading throughout the rest of his body from his arm. The immense weight in his hand steadily felt heavier by the second, Derek chalking it up to reaching muscle failure. He thought that it was odd that he’d reached it in under a minute since he could usually lift heavy amounts of weight for a substantiated amount of time.

Derek grunted as he attempted to perform one more rep, yet his arm started to shake and he ultimately dropped the weight, letting it clang loudly onto the floor. 

The guy chuckled again, and clapped Derek on the bare shoulder. “Don’t worry, Little Guy,” he teased, “there’s no shame in starting off with the smaller weights. We all gotta start somewhere, right?”

Derek swallowed down a growl and instead tried to glare threateningly at the other guy to get him to leave him alone… but he stopped when he stared directly at the dude’s chin. Earlier, Derek could’ve sworn that they’d stood eye to eye.

Derek’s eyes widened when he witnessed the other guy actually growing. As impossible as it seemed, the other gym goer sprouted up in height, his muscles also packing on some serious size. His pecs plumped out even more and his arms took on some more consider meat. 

“What the fuck?” Derek muttered, freezing when he heard his voice. It was void of any baritone, making his voice sound lighter and almost squeakier, as if it had shot up a few octaves. 

Then the horror slowly dawned on Derek that the other guy wasn’t just growing, but Derek was also shrinking.

Derek watched as his line of sight kept slipping lower and lower, until he was staring directly at the other man’s plump pecs. It didn’t stop there though, as all of Derek’s muscles began to deflate. 

“What the fuck’s happening to my muscles!?” Derek squeaked out in his smaller voice, holding his arms out in horror as his biceps steadily grew flatter.

Derek was helpless to do anything except watch as all of his hard-earned muscles grew flatter and near nonexistent. His arms shrank until they looked like unremarkable sticks, lacking any bulges whatsoever. His pumped up pectorals gradually flattened as they shrank against his chest, looking smaller and smaller until his entire torso was flat— lacking major pecs or even any abs. Even his legs thinned out as quads and calves deflated, growing smaller until Derek had little twigs to stand on.

To add insult to injury, Derek paled as he squirmed and felt an uncomfortable bagginess in the front of his boxers, the front of his shorts looking flat.

When he was finally done shrinking, Derek stared at his skinny body in shock and horror, estimating that he must’ve lost well over fifty pounds of pure muscle, and that he had to have stood at a measly 5’3” now.

“Wh-what did you do to me?” Derek roared, but his lighter voice didn’t hold any sort of threatening quality to it at all. In his frustration, he tried to charge forward and pummel the now larger man, but as he swung his tiny fists at the man’s massive bulk, the other guy didn’t seem phased.

The big gym bully just snickered. “Sorry, Little Man,” he scoffed, gently shoving Derek away, yet the incredible difference in strength sent the tiny alpha stumbling backwards until he fell on his tiny butt with a thud. “There’s only room here for one gym alpha.” 

To illustrate his point, the larger man lifted his powerful arms and flexed his massive biceps which flexed to the size of small melons, easily out sizing Derek’s tiny stick-like arms.

Out of humiliation, Derek took off, sprinting out of the gym in a frenzy, embarrassed at how there was a lack of dangling sensation between his legs. He hurried into his Camaro and nearly wailed as he had to readjust his seat closer to the wheel because his shortened legs couldn’t reach the pedals.

As the tiny man sped off, a large bodybuilder entered the gym, his large muscles oddly already starting to burn the second the stepped foot inside…
