Day 17: Nippleslüt

Alpha Derek Hale was taking a shower, a little irritated that he was rock hard and his husband was working the nightshift. Normally whenever Derek got a little frisky, he was all too happy to rush over to Stiles and go to town. However, he was a little miffed that he was all cocked and loaded, yet he was stuck all by himself with just his hand.

“Damn it,” Derek growled as he pumped away at his throbbing cock, even using some of Stiles’s shampoo to help do the trick.

Still, jerking off just failed in comparison to actually fucking. 

Derek was about to just give up and turn the water to ice cold when he spotted an unknown blue vial in the shower. Picking it up, he eyed it and read out the chicken scratch writing on the label that read out Liquid Lust. 

“‘Liquid Lust’?” Derek scoffed, rolling his eyes at his husband’s antics. Stiles had been practicing potions with Deaton, and every so often, Derek would find remnants of his experiments around the house.

Still, wanting to encourage his lover’s endeavors, Derek opened the vial and sniffed at the concoction. It reeked of musk, making the alpha gag and flinch.

Unfortunately, Derek’s jerky movements caused him to lose grip of the tiny vial in the shower, leading it to falling out of his grasp.

“Fuck!” Derek huffed as the smelly liquid fell out of the bottle and landed all over his hairy chest. It splattered across his pectorals, seemingly absorbing straight into his skin. The musky aroma clinging to Derek like it was emanating from him directly.

Immediately, Derek felt his nipples go hard. The little nips perked up before actually stretching out and elongating, inflating until they were large and nubby, looking like a pair of thumbs attached to his chest.

“What the hell?” Derek gasped as he looked down at his altered nipples. He tentatively reached up with one of his hands to prod at them. “What kind of potion is this— OOoohhhh!”

Merely grazing his fingers against his enlarged nipples sent a ripple of pleasure throughout Derek, his voice breaking out into a moan as his knees buckled. His cock throbbed even more, leaking precum. It was like a surge of pleasure never felt before. No amount of sex or jerking off had ever felt nearly as good as just touching his nipple just had.

“Wha-what the fuck is going on?” Derek panted, his meaty, hairy pecs heaving up and down as he struggled to catch his breath. His nipples seemed to burn with want, their own hardness competing with his cock’s, demanding attention from the alpha.

Almost unable to control himself, Derek reached up with both hands, running his thumbs over his hard nubs.

“Uuugghhh!” he squealed, his head rolling back as he toyed with his chest. The pleasure was mind-numbing, and Derek was helpless to do anything besides rub his nipples.

This soon turned to him grabbing a strong hold of both of them with his hands, lightly tugging on his huge nipples. It felt as if Derek had two cocks on his chest, his ignored dick bobbing uselessly between his meaty thighs as he pinched his big nips.

“Oohh fuuuck,” Derek bellowed out, the normally silent guy unable to stop moaning loudly, his deep voice echoing throughout the bathroom. “Holy shit, that feels so good— UUGHHH!”

Derek nearly shrieked as he came, his cock erupting and spewing out globs of cum that splattered against the linoleum in the shower. Basking in the post-orgasmic bliss, the werewolf felt as if he’d just shot the largest load of his life. He couldn’t help but chuckle in disbelief as he tried to catch his breath.

“Holy shit,” he breathed, rinsing away his cum off the walls. His nipples remained perky and hard, and after masturbating by tugging on them once more, Derek finished his shower and toweled off.

He wiped the steam away from the mirror and frowned when he saw that his nipples were still huge and hard. They poked noticeably off his chest, looking ridiculous on his muscular, alpha male frame.

“Um, maybe this’ll wear off in the morning?” he guessed as he glanced at the vial of the liquid lust, finding no other information about it on the bottle. 

Derek stumbled over to his bedroom, biting down on his lower lip at the shiver that traveled down his spine as the cool air from the A/C blew over his hairy chest, caressing his hard nipples. Just that light sensation was enough to make his cock begin to stir back to life, but he tried to ignore it.

He walked over to his shirt to try to cover his chest, but that proved to be another problem.

“Uuughh!” Derek moaned out again as soon as he tugged his shirt on. His nipples poked against the fabric like crazy, and just the cotton running over the nubs was enough to cause his cock to go erect and shoot out cum.

Derek had to rip the shirt away off of him, panting as he gained a reprieve for his sensitive chest. “What the fuck’s happening to me?” he gasped, his nipples almost simmering in the air as they begged for his attention some more.

That night Derek barely got any sleep at all. He would try to lie down on his back, but whenever the covers brushed up against his hard nipples, he’d go rock hard and have to tug on his nips to ease his horniness. Whenever he tried to lie on his front, it led to the alpha uncontrollably squirming against the mattress, moaning loudly as he ground his chest against the hard mattress, loving how it felt to rub his nipples against it, but also humiliated over what a huge nippleslut he was turning into.

“What the fuck am I supposed to do with these?!” he roared in frustration, looking down at his big nipples. 

When morning came, Derek was slightly relieved to hear the front door opening, meaning that Stiles had come home.

Derek leapt out of the cum-covered bed and raced downstairs to his husband, eager for some answers.

“Hey, Der— what happened to your nipples?” a tired-looking Stiles asked from the entryway once he saw the large nubs attached his husband’s muscled chest.

Derek gestured down at his nubby nipples with a shaky hand. “I accidentally spilt some of that liquid lust potion of yours on them, and now they’re— this! And they’re super sensitive!” he growled, his cock already starting to twitch at the mere thought of playing with his chest again.

Stiles’s eyes widened. “You messed with my potion?” he gasped in shock. “That was just a test. I don’t know if there’s a cure for it.”

Derek paled. “So I’m stuck like this?” he asked, looking down at his hard and sensitive nipples, imagining a life where he’d have to walk around constantly shirtless with his massive nubs on display. They’re so sensitive that he seriously doubted that he’d ever be able to get off again without someone playing with his nipples.

Stiles frowned for a moment before offering a meek smile. “If it helps,” he said, slowly reaching up, “I could play with them, if you’d like?”

He reached up and ran his thumb over one of the nubby nipples, and Derek instantly swooned.

“Ooohhh,” he moaned, his cock going straight to attention. “P-please, play with them some more.” He leaned forward and shoved his chest towards Stiles, looking forward to spending the day having Stiles play with his enlarged nipples, the nubs already tingling with anticipation.

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 09: Merge

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

“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 25: Roided

The host, Matthew Johnson, walked back onstage, eliciting thunderous applause from the crowd. He was a handsome man dressed in pristine white clothes that were tailored to tastefully show off his muscled body.

“Welcome back everyone to The Matthew Johnson Show,” the host smiled to the live studio audience. “We are continuing our series called ‘Living with Curses’. Just last week, we chatted with Scott, the man cursed to shrink down to only five inches tall!”

The audience roared with laughter at the memory of the pipsqueak Scott.

“But today,” Matthew continued, “we have another man here who’s been living with a curse for about two months now. And unlike Scott last week, this curse has caused this man to grow! Everyone, please welcome to the stage: Derek Hale!”

A stunned silence blew over the crowd as Derek Hale walked onto the stage… well, more like waddled onto the stage.

Derek Hale was a massive muscle monster! That was putting it lightly too, because the stud was insanely large. Almost as wide as he was tall, Derek looked like he was struggling to lumber around. His thighs were about as thick as the host’s waist, and they rolled over one another with every step the bulky man took. They pressed against each other, causing the man to have a wide stance. A bulbous roidgut protruded out in front of Derek, making him look almost pregnant with how massive it was. It was round and didn’t jiggle at all, indicating that there wasn’t a trace of fat on his over-muscled form. His pecs were huge and round, and they rested on top of his gut; large, nubby nipples poked noticeably against the tight t-shirt that struggled to contain Derek’s bulk. His back was wide and his shoulders were insanely broad, having to be large enough to carry his enormous arms. Biceps the size of Derek’s head tore through the tight sleeves of his shirt, pressing against his flaring lats that caused his arms to hang at ninety-degree angle.

Derek was so large that he made Matthew look puny by comparison. He was larger than any other bodybuilder that had ever been on TV, and he had such an enormous gut that it seemed to be the epicenter of his growth— being the largest part of him.

As he moved, the hunk breathed heavily and blushed bright red as the stage lights were on him, broadcasting his enlarged form to all of American daytime TV.

Matthew handed Derek a microphone, and the muscled up guest struggled to bend his massive arm enough to bring it up to his mouth, the movement causing his bicep to flex with power.

“Welcome to the show, Derek,” Matthew said. “Now, let me try to understand this: You weren’t this muscular two months ago, were you?”

Derek’s blush deepened and he shook his head. “No,” he grunted in a deep voice that was full of baritone.

On the screen behind the two men appeared a picture of Derek before he was cursed, showing off a toned man that was about a third the size of the swollen bodybuilder onstage.

“You where what, one-hundred eighty pounds in this picture?” Matthew pressed, gesturing towards the image on the screen. “And now you weigh how much?”

Derek took a hesitant look over at the audience, thankful that the positioning of the stage lights prevented him from making out any faces. He was beyond humiliated standing up on stage in his overgrown bulk, but after running out of ideas and failed spells from Deaton, it was his last hope at returning to his usual size.

“Um,” Derek mumbled nervously, “I weigh three-hundred seventy-nine pounds now…”

A loud gasp ran through the audience.

“And tell us, how did you get so big?” Matthew asked, placing a sympathetic hand on Derek’s broad shoulder. The size difference between the two made Matthew’s hand look utterly tiny.

Derek sighed loudly, the movement causing his massive shoulders to rise and fall, his shirt seams groaning at the movement. “I was at the gym and got into an argument with some guy,” Derek growled, anger written all over his face as he remembered what had happened. “Words were said, and I called him a ‘Roided-Up Freak’. Then he snapped his fingers, and well…” Derek gestured downwards at himself.

Matthew nodded quietly, and then perked up. “And I understand that your boyfriend, Stiles, has stayed by your side this entire time?”

The audience let out aww’s and coos.

Derek nodded as best as he could due to his huge traps swallowing his neck. “Yeah,” he said. “He’s… my rock.” He admitted it, his heart racing over how grateful he was for Stiles. 

Like Derek, Stiles had been freaked out too when Derek had turned into a roid-loving bodybuilder. He’d tried his best to find spells to turn him back to normal, or at least find clothes big enough to fit over his unwanted bulk. However, unlike Derek, Stiles quickly came around to his boyfriend’s new appearance. He would run admiring hands over Derek’s inflated pecs or marvel over how he couldn’t fit hit hands even halfway around Derek’s biceps… and despite being annoyed, Derek would be lying if he didn’t admit that deep down that he loved having Stiles worship his muscles.

However, despite how great life was with Stiles, Derek was still irritated over his bulky body ruining his life. He couldn’t fit in his prized Camaro anymore. His gut and pecs were too big and they constantly pressed against the horn. Plus, his back was so wide that he couldn’t even close the door thanks to how broad he was. Speaking of doors, it took all of Derek’s cleverness to squeeze himself through any standard-sized one. He always had to go through them sideways thanks to his broad shoulders, but it was always a struggle fitting his roidgut and pecs through the doorway. All of his clothes were now XXXL, and they always looked like they were painted on. Even sleeping was struggle too! Whenever he lied on his back, Derek’s huge back muscles kept his head elevated above his pillow. He couldn’t lie on his side, not with his large arms and lats. His gut and pecs were too big to try sleeping on his front. He had to position pillows and blankets carefully around his body in order to get comfortable. But his large body left zero room for Stiles, forcing the tiny human to sleep completely on top of Derek’s large muscles… but Derek secretly liked that part of the curse.

As the show went on and Derek answered the host’s questions, a loud ripping noise echoed out.

“Oh no…” Derek groaned as his shirt finally lost its battle trying to conceal his bulk. The collar split right down the middle of his pillowy pecs, traveling downward to his gut. His sleeves burst to shreds over his enormous biceps, leaving the large bodybuilder completely topless. Derek blushed, and then winced when he heard another loud tear, this time his huge glutes bursting through the back of his tight pants. Now that he was exposed, his vascular form was on full display, showing off the radiating veins all over his huge physique.

Matthew mock frowned, yet the audience erupted into a fit of laughter, making Derek blush even more.

“Well, Derek,” Matthew said, “we looked into your curse to see if we could help you at all. And guess what? We can.”

Derek perked up a little, hopeful at returning to his normal body after months of being trapped in an overblown, roided-up bodybuilder’s body. “R-really?” he asked, hopeful. 

Matthew reached into his back pocket and handed Derek a card. “Yes, Big Guy,” he smiled. “This here is a fifty dollar gift card to Mens’ Big and Tall. They have all sorts of styles designed specifically for large, bulky men such as yourself.”

Derek frowned as he snatched the gift card away from the host.

Matthew turned back to the crowd. “And coming up after our break, a man whose voice sounds like a chipmunk’s! That and more on The Matthew Johnson Show!”

Derek waddled off the stage, grumbling angrily to himself the whole time. He’d just embarrassed himself on TV for a stupid gift card. “I hope his shit show gets cancelled,” he muttered to himself as he walked backstage towards a waiting Stiles.

Stiles looked up at his inflated boyfriend sympathetically. “Sorry Derek,” he frowned. “I thought that it’d help. I mean, it looked like he helped people whenever I’d watch him on TV.”

Derek huffed and had to take a step backward so that his protruding pecs weren’t blocking his view of Stiles. “Yeah, who would’ve guessed that people lie on TV?” he rolled his eyes.

Stiles’s frown lightened up the smallest bit. “Well, I mean, if you are stuck as a big bodybuilder…” he led, looking at Derek with a hopeful expression.

Derek sighed, but forced a grin on his face as he lifted his muscled arms as best as he could, forming a double biceps pose. “Wanna feel, Little Man?” he asked the usual line that had become a staple in their bedroom activities.

Stiles’s smile grew. “Yes, please.”

Derek couldn’t help but smile back, reaching over and tossing Stiles over his broad shoulder with ease. “I could get used to this, I suppose,” he shrugged to himself as he waddled off, loving how small his boyfriend felt against his bulk.

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.

31 Days of Derek Hale

Day 16: Himbo

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

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.
