For @writer-ofstuff! It was really fun writing this one! And I’ve been really enjoying writing stories surrounding Derek and Stiles!

– – –

“This is stupid,” Derek grunted as he and Stiles took their seats in the front row, right in front of the wrestling ring. “Everyone knows these things are staged. If you really want to see a good match, then I should take you to a werewolf wrestling match.”

Stiles perked up, clutching his popcorn close to his chest in shock. “They have those?” he gasped, his mouth full of kernels.

Derek just scowled down at the human, his attempt at joking failing. “No,” he muttered, sitting down with his angry expression still all over his face.

“Dude,” Stiles elbowed him in the ribs, “you agreed that I could pick the location for Date Night every Fifth Friday of the month. It’s not my fault you didn’t pay attention to the calendar.”

Derek growled something under his breath, but still put his arm around his boyfriend’s slender shoulders, both to comfort him and also because one of the wrestlers was making his way towards the ring, staring at them. He was clad in a black speedo that had blue designs over it.

Derek scowled back and tightened his grip on his blissfully unaware boyfriend, even baring his teeth at the staring wrestler.

The muscled man just smirked and… blew a kiss at Derek?

The alpha werewolf cocked his eyebrow and broke eye contact.

The announcer stepped into the middle of the ring and began his spiel, his deep voice echoing out over the crowd of spectators who cheered wildly. Stiles got caught up in the excitement and leapt to his feet to cheer at the top of his lungs.

“We begin our night with the Tag Team Match!” the announcer roared out, followed by an eruption from the crowd.

Stiles leaned in closer to Derek so that he could explain what was happening to his boyfriend, hoping that he’d enjoy the night too. “So Tag Team is when there’s two versus two… like a team,” he laughed, looking over at his boyfriend to see if he was paying attention.

Derek stood beside him, crossing his arms over his white t-shirt that stretched over his muscular chest.

Stiles looked at him in confusion. “Hey Der, what happened to your leather jacket?” he asked, wondering why the werewolf was wearing only his t-shirt which looked like it was painted on. He even glanced at the seat, seeing no sign of his boyfriend’s jacket in sight.

Derek looked down at his torso and shrugged. “I… I’m not sure,” he muttered, his thick eyebrows knitting together.

The announcer continued. “Introducing our first team! On my right,” he roared out, “we have…”

“I’ve seen this guy before at a match I went to with my dad,” Stiles told Derek. “It was a few years ago and— Um, Derek? D-did you dye your hair?”

Sure enough, Derek’s usual black hair was taking on a light hue, looking like could’ve been dirty blond. There were a ton of laser lights in the building, so Stiles told himself he was seeing things.

The announcer carried on, the first member of one of the tag teams storming into the ring and raising his muscled arms above his head, earning a mixture of cheers and boos from the crowd.

Out of the corner of his eye, Stiles could see Derek straighten up, looking like he was actually starting to get into the show. He smiled to himself, happy to be spending such quality time with his boyfriend. Beacon Hills seemed to be an epicenter for all things supernatural, so on the rare occasions he and Derek got to be a normal couple, he wanted to take full advantage.

He leaned into Derek affectionately. “Thanks for taking me here,” Stiles mused, basking in the warmth he felt when Derek wrapped his arm around his shoulders. The heat from Derek’s bare, smooth skin warmed him up and made him feel at home—

Stiles jerked back and stared at the shirtless and definitely blond Derek in shock and awe.

“Dude!’ Stiles cried, almost dropping his popcorn to the ground, but managing to save it. “Your shirt! And your hair!”

Derek looked down at him, confusion written all over his face. “What about them?” he asked the shocked human, his voice sounding a bit deeper and slower. “You feelin’ okay, Bruh? You look a little pale.”

Stiles knew something was happening, he was certain of it. He scanned the crowd for something or someone who looked out of place. However, it was so dark out in the stands that he couldn’t discern separate faces well, and the announcer was loud as the second member of the first tag team entered the ring.

He clutched Derek’s hand tightly, refusing to let it go. “We gotta get you out of here,” he hissed to the werewolf.

Derek jerked back in shock. “Huh?” he asked. “But why, Babe? We just made it, don’cha wanna see the match?”

“Nevermind that! And why are you talking like that?” Stiles cried out, throwing his free hand up in the air frantically. He then paused when he took in the new change. “And why are you wearing those?”

Derek looked down at the black and pink pair of speedos that he wore. They were so small that they forced his bulge out in front of him and cupped his bubblebutt perfectly, even lifting it to accentuate its fullness. Derek grinned as he looked down at it, smiling at his boyfriend. “Looks hot, right?” he smirked.

The announcer continued to bring out the wrestlers. “And, introducing the second team!” he announced. “The first member, with four wins and zero losses: The Trickster!”

The crowd roared with excitement as a muscled man in black and blue speedos ran up and entered the ring, flexing a large bicep for all to see.

Stiles’s eyes widened as he finally witnessed firsthand Derek’s mysterious transformation. The werewolf tensed up and his muscles inflated. His pecs pushed out further in front of him, his nipples even perking up. His shoulders broadened while his back widened, making Derek so wide that he’d have to turn sideways to walk through any standard-sized door from now on. His butt packed on more meat, his thighs following suit to support the weight of the massive pillows, pushing his large bulge further out in front of himself. Lastly, Derek’s already large biceps ballooned in size, resembling bowling balls. By the end of his musclegrowth, Derek resembled a blond wrestler, his pale skin looking slick as it was somehow getting covered in posing oil, making his abs and every contour of his musculature pop.

“And the last member of the second team,” the announcer roared out, “he’s a newbie! Weighing in at an impressive 248: The Wolf!”

The newly transfigured Derek threw his head back and let out a loud howl, making the crowd erupt in cheers. He yanked Stiles into his oily, muscled body, giving the stunned human a hot, possessive kiss. Despite how deep in shock he was over watching his boyfriend somehow turn into a muscled up wrestler in tight speedos, Stiles couldn’t help but feel so turned on by the feeling of Derek’s rock hard muscles.

He let go and waddled up to the ring, his massive muscled thighs rolling over each other and his broad back swaying back and forth with power. His arms were so thick with muscle that they hung akimbo at his sides. Even though he’d been transformed, the new Derek still had his trademark scowl as he entered the ring and stared down the opposing team intimidatingly before flexing his massive chest muscles, oozing masculine power.

Stiles’s heart picked up speed as he watched his altered boyfriend kick ass in the wrestling ring, noting the look of utter jubilation on the werewolf’s face as he fought. He really looked like he was enjoying their Date Night, although it really wasn’t the way Stiles had intended.

The new wrestler Derek looked over at Stiles, giving him a wink and making one of his inflated pecs bounce.

“Oh hot damn,” Stiles gasped. Yeah, he could live with this.

Someone snuck some growth formula into Daddy's morning coffee. He's a little annoyed that none of his shirts fit anymore, but he'll get over it.
