Derek wasn’t proud to admit it, but he had a little bit of a jealous side.
Nothing brought out the green-eyed monster more than watching some guy try to flirt with Stiles, or even hearing Stiles comment on how hot he thought a certain actor was. The other day, Stiles was talking to Lydia, and he’d mentioned how he’d thought that the new Superman actor was cute. Derek had to swallow down a growl, and he’d not-so-subtly changed into his Superman t-shirt afterwards.
Stiles didn’t seem to mind too much, or if he did, he didn’t say anything. He’d usually just laugh it off and give his husband a big hug, trying to calm him down.
This all came to a culmination when the water heater when out.
“Der, I had to call a plumber to come fix the water heater,” Stiles told the werewolf. “He said he should be here soon.”
Derek just grunted from his spot on the sofa. He mindlessly munched on beef jerky as he watched TV, clad in just his sweatpants. He was so caught up in watching Alexander Skarsgård swinging through the jungle as Tarzan, that he’d barely heard the doorbell ring.
“I’ll get it!” Stiles called out as he hurried over to the front door, swinging it wide open.
“Hello, Mr. Hale,” a deep voice bellowed out, making Derek perk up, “I’m Chase, I’m here to fix your water heater.”
“Oh yes!” Stiles breathed, sounding relieved. “Come in, please.”
Derek turned around to stare down the other man who entered his house, frowning at the muscular stud who followed behind Stiles. The alpha werewolf couldn’t help but narrow his eyes in the direction of the plumber who wore a blue uniform. The young man was so built and muscular that he left the top three buttons of his shirt undone, showing off his impressive hairy pecs. His sleeves were rolled up, allowing his bowling ball sized biceps to curl out of them. In front of his tight jeans was a large bulge that made it look like the young man was smuggling a grapefruit in his pants. And when the plumber walked, his firm butt pressed tantalizingly against his jeans which were so tight that they rode a little low, giving credence to the term “Plumber’s Crack”. His dirty blond hair was combed in that style that made it look slightly messy, but sill manageable, and his lantern jaw was covered in masculine stubble. The dude seriously looked like he’d been ripped straight out of a porno.
Immediately, jealousy surged though Derek and he felt himself leap off the couch and hurry over towards Stiles, wrapping a possessive arm around his waist. He puffed out his own sizable pecs and forced a smile on his face. “Yes,” Derek almost growled, his voice rougher than intended, “please come into our home.”
Stiles shot him a look.
Chase only smirked as he entered the home, his heavy footsteps thudding loudly as he followed behind the couple.
“The water heater’s in the basement,” Stiles babbled on. “It went out last night and the water’s been ice cold ever since. You’re a real lifesaver for coming on such short notice.”
“It’s all part of the job,” Chase said, giving Stiles a crooked grin.
Derek bit down on his lower lip to hold back his snarl. “I could’ve fixed it,” he added hurriedly, “but I have a lot on plate since I run my own auto shop. So you know, management is very time-consuming work that only tough guys can do.”
“Wh-what?” Stiles wondered aloud.
Chase shrugged it off. “Sure,” he coughed. “A lot of wives tend to call me when their husbands can’t fix a simple appliance. It’s nothing to be ashamed about.”
Derek saw red and his fists shook with rage. He had to take a few deep breaths to prevent himself from phasing on the spot and mauling the cocky plumber… when a devious plan entered his head.
“It’s, uh, kinda hot down here,” he stated, forcing a toothy grin onto his face, “why don’t I get us some drinks.”
“I can get them,” Stiles offered.
“No!” Derek hurried, as he practically sprinted back up the basement stairs towards the kitchen. The werewolf tore through the cabinets as he grabbed three cups, making sure to grab Stiles’s favorite Superman glass. He then snatched the jug of Crystal Light out of the fridge before grabbing the secret ingredient from under the sink.
Derek couldn’t help but smile maniacally at the translucent powder that possessed a pink shimmer to it. It was a magical powder that Peter had made, claiming that it would cause “Embarrassing Side Affects that varied from person to person”. Derek had no clue exactly what that entailed, but he figured that annoying, sexy Chase would be the perfect tester to try it out.
The jealous werewolf made sure to pour Stiles’s glass first, setting it far away on the counter so that it wouldn’t come into accidental contact with the powder. That left two unmarked cups, and in his haste, Derek filled them both to the brim with the red Crystal Light. He then dumped a large spoonful of the mysterious powder into one of the glasses, marveling as it immediately dissolved, leaving zero trace of its presence behind. The giddy werewolf was so caught up in imagining all of the humiliating scenarios that played in his head involving Chase, that he put the jug of Crystal Light back into the fridge without memorizing which glass he’d spiked with the powder.
Derek froze as he stared at the two unmarked glasses on the counter, both of hem equally filled up with red juice.
“Damn it,” he snarled, making move to dump them both down the sink to try again, but then something caught his ears.
The werewolf bristled as he heard Stiles’s laughter echo out from the basement, the deep bellowing of Chase’s annoying voice trailing behind.
With a ferocious growl, Derek dumped a spoonful of the powder into each of the unmarked glasses. He grabbed all three of them and raced back down the stairs, eager to break up the laughing session between the stupid plumber and his husband.
“H-hey, what’s so funny?” Derek asked, forcing a cheerful smile onto his face as he walked down the basement stairs. Despite his grin, his eyes narrowed in Chase’s direction. He walked up to Stiles and handed him the Superman glass that wasn’t spiked with the embarrassing potion.
“Chase here went to Beacon Hills High, too!” Stiles exclaimed. “I knew he looked familiar. We were in the same Spanish class.” He looked over towards the plumber. “You’ve put on some serious muscle.”
Chase held his head up high as he flexed a large bicep. “Yeah, I’ve been getting into bodybuilding,” he grunted. “You should check out my Instagram. I post tons of progress photos there.”
Over my dead body, Derek wanted to say, but instead he held out a glass for Chase. “Here,” he forcefully smiled, “I hope you like Crystal Light.”
“Thanks,” Chase obliviously said, accepting the glass and bringing it up to his full lips. He paused for a second, eying the water heater in the corner of the basement. “Oh, I can see a leak from here.”
“A leak?!” Stiles repeated incredulously, rushing forward to inspect the large machine as best as he could. “Where?”
Chase lumbered towards him, positioning himself way too close for Derek’s liking. “There,” he said, pointing towards a small spray of water.
For the millionth time, Derek was seeing red, beyond irritated that the muscleman was getting close and personal to his husband. In his anger, he briefly forgot that he was supposed to wait for Chase to take the first sip of his drink, and brought the glass up to his own lips to take a large gulp of the sweet juice.
Instantaneously, Derek’s eyes widened when he’d realized his mistake, quickly placing the half-emptied glass onto a nearby fixture. His heart raced in his chest as he waited for something to happen, holding his breath as he prepared for the worst.
“Damn,” Stiles frowned as he examined the leak, “do you see this, Derek?”
“Derek see,” Derek bellowed, his voice sounding much deeper and guttural than normal, making the werewolf flinch in shock. He had no idea why he’d referred to himself in the third person, so he cleared his throat and tried a second time. “Ook!”
Stiles only chuckled, his back still turned to Derek, thinking that his husband was just trying to be cute.
Meanwhile, Derek’s panic grew when he felt himself beginning to itch. He looked down at his chest and gasped as he watched wisps of black hair sprout all over his toned pectorals. The naturally smooth werewolf was stunned silent as he watched his hair thicken, and not just over his chest. He held his shaky hands up in front of his face, paling as hair grew over his arms, traveling towards his wrists and even his knuckles.
Derek felt his center of gravity rapidly shift, and he stumbled on his feet, falling over. He managed to catch himself before hitting the hard ground. Yet, he noticed that he was perched using his knuckles for support, reminding him of those lumbering gorillas he’d seen on TV. He tried to stand up straight on his two legs, but he could make it about halfway before toppling back down on all fours like an ape.
As a final touch, Derek nearly went cross eyed as he watched the bulge in his sweatpants steadily grow larger. The bulge inflated as it grew, causing his enlarged cock to stiffen and snake down his pant leg, looking ridiculously big on his toned, hairy form.
His heart raced in his hairy chest as Derek realized that he’d turned into some sort of monkey man. “Derek feel funny,” he muttered in his deeper voice, bristling at the awkward way he spoke. His thoughts were still coherent, but he couldn’t get his mouth to cooperate with what he wanted to say.
“Huh?” Stiles asked, looking over his shoulder before gasping at his hunched over, hairy husband. “Derek?! What the hell happened?!”
“Ook! Ook!” Derek bellowed, jumping up and down in his crouched position. His blush deepened when Stiles walked up to him, standing tall above his hunched over body.
Chase only glanced over this broad shoulder before shrugging and continuing to examine the water heater.
At the sight of Chase’s glare, Derek felt his possessive side spark once more. However, instead of silently brooding, the werewolf felt himself puff out his hairy chest. His muscles tensed, he beat at his chest with both of his meaty fists, mimicking a large gorilla. Again, he internally winced at his uncontrollable actions, but he couldn’t help it. Derek could only bare his teeth as he beat his chest intimidatingly.
Stiles’s eyebrows lowered slowly as he put the pieces together gradually. “Ohhh,” he hummed, eying the glass of Crystal Light.
Derek stopped beating his chest and cheekily smiled up at his husband. “Ook!” he grunted, nuzzling against the other man’s leg in an attempt at an apology.
Stiles snickered a little bit. “You’re silly, Derek, you know that right?” he chuckled as he ran his fingers through Derek’s hair.
“Ook! Ook!” Derek happily cheered as he bounced in place, his hard cock bobbing up and down wildly in his sweats. It wasn’t his intention to turn himself into some feral caveman, but he couldn’t deny that he liked how Stiles was paying much more attention to him now than he was to Chase.
“Your husband’s weird,” Chase muttered, rolling his eyes at Derek, who only beat his chest in uncontrollable response. The muscled plumber finally brought the glass of red Crystal Light up to his lips, taking a loud gulp.
“Ook!” Derek grunted as he watched the changes happen automatically.
Chase must not have felt anything, but as he drank down the cursed drink, Derek and Stiles stared in awe as the large bulge in front of his pants shuddered before growing less prominent. The previous mound that had looked like a grapefruit grew smaller and smaller by the second until the front of Chase’s jeans were flat and unremarkable.
When the glass was empty, Chase lowered it and wiped his lips. “This tastes kinda funny,” he said, freezing up in fear at the sound of his voice. His usual deep baritone was gone, replaced with a cartoonish voice that was hilariously high-pitched and squeaky, sounding just like a chipmunk’s.
Stiles had to cover his mouth to keep from bursting into hysterics.
“Oook! Ook!” Derek bellowed, happily slamming his fists down onto the ground in victory. He couldn’t hide the dim smile that stretched out his face, and he puffed out his hairier chest with pride.
Chase blushed a little and cleared his throat. “Um, *ahem, what I meant to say, *ahem, what’s wrong with my voice?!” The muscle man clutched at his throat, his face burning red at the sound of his cartoonish voice.
Stiles, unable to contain himself, broke down and doubled over with laughter. “That’s not it!” he guffawed, tears welling up in his eyes at the sight of the squeaky-voice muscleman.
“What do you mean?” Chase squeaked, stomping his foot in irritation, his voice making it sound more like he was throwing a tantrum than trying to be threatening.
“Tiny!” Derek managed to say, bouncing up and down excitedly on his feet and fists, like a chimp at the zoo.
“‘Tiny’?” Chase repeated, still blushing over the sound of his new voice. His eyes followed the direction of Derek’s stare. He gasped when he saw the flat front of his jeans and immediately unbuttoned his pants, shoving them down. The pathetic two inch nub looked completely out of place on Chase’s muscled frame. It was so small and puny that it was barely noticeable in his trimmed bush.
Chase screamed, his voice sounding even higher than before. He yanked his pants up and ran up the stairs in a hurry, exiting the house in a panic.
Stiles continued to laugh for a few more minutes before he was able to slightly contain himself. “That, haha, wasn’t nice Derek,” he tried to frown, but his chuckling ruined the mood he was trying to portray.
Still, Derek hung his head in shame. “Derek sorry,” he muttered in his slow voice.
Stiles smiled down at his husband and ran an admiring hand through his thick hair. “It’s okay, I guess,” he hummed. “You don’t have to be so jealous, Sourwolf. I love you.”
At this, Derek felt himself perk up, his lengthened cock rocketing to attention. The caveman werewolf beat his hairy chest with pride, a wide smile on his dim face. He then reached over and tossed Stiles over his shoulder, carrying him upstairs towards their bedroom as he readied to show his husband just what a wild man he now was.
