Chapter Text
Derek almost drops the beer he's been nursing, when he sees Stiles come in to meet the rest of the pack. They were all meeting up to go clubbing for Halloween. Everyone, except Derek ofcourse, is dressed up. Scott, Allison, Lydia, Jackson, and Boyd are the gang from Scooby Doo. Jackson is Fred, Allison is sexy Velma, Lydia is Daphne, Scott is Shaggy, and Boyd is Scooby Doo. They all actually really nice, (not that Derek would ever tell them that but still). Isaac even dressed up, as Apollo from Greek mythology.
But Stiles
As many superheros that Stiles obsessed over constantly, he didn't come as any of them. Derek could have handled Stiles as Batman WAY easier than what stood a few feet away from him.
Stiles was dressed as Princess Leia. Derek, subtly, took in the costume. If you can even call it that, there was skin everwhere. A long braided wig that drew his eyes down to the tight halter top that stretched across his pale, lightly muscled chest. Down to his skirt-ish bikini bottom that lay just below his hip bones and rode down a little further, everytime he moved. The bottoms were tight. Like, really, tight. Whenever he moved too fast, the skirt would move and Derek could see the outline of his--
"DEREEEKK" he heard Scott call, smirking slightly. "Are you ready to go? The pack's all here"
Derek blinked, chugged the last of his beer, and cleared his throat.
"Uhh yeah, let's go." he replied, looking anywhere but Stiles.
Derek could smell the excitment coming from his pack but he couldn't bring himself to join in. He could tell this night was going to be a rough one. That was clear from the minute Stiles walked in.
The night only got worse when the pack told Derek that the Scooby Doo gang all wanted to ride together, leaving him to drive Isaac. And Stiles.
He reluctantly agreed, being as Isaac would be in the car and that would help control himself enough to not claim Stiles right then and there. But it still wasn't easy because Stiles sat shotgun and now that they were this close, Derek could really see the details of the costume. The shimmery fabric that clung desperately to every part of Stiles' perfect skin, the fucking pink-ish lipstick on those lips that Derek fantasized about being wrapped, warm and wet, around his cock.
Derek shook his head and glued his eyes back to the road ahead. When did he get so sprung over the spastic, talkative, sassy, teenage human?? At first he figured it was just sexual atrraction, because he could smell the scent of arousal that came off of Stiles whenever they were together, added to the fact that he hadn't gotten laid in years. Years. But the more time that he interacted with the younger boy and the more they saved each others lives, Derek realized that Stiles was perfect for him. Stiles was his. It explained his possessiveness when other guys flirted with Stiles. He wanted Stiles as his mate and his wolf couldn't agree more. Then why hadn't Derek made a move yet? Stiles was of age now. So what was holding Derek back?
He pushed these thoughts aside as they pulled up to club. Before the car was parked, Isaac was out and running to meet the rest of the pack. Leaving Derek alone. With Stiles.
Stiles wasn't in a rush to get out, as he just sat there looking straight ahead, knee shaking nervously. His heart was beating faster than usual.
"Stiles, we're here. Why are you still sitting?" Derek suddenly spoke into the silence, trying not to sound too wound up and intimidating. It didn't work.
Stiles flinched slightly before shaking his head and answering,
"Uhh oh yeah! sorry dude, I just got lost in my own head. Happens sometimes...hey you never complemented my costume! That's kinda rude considering you're the only other Star Wars enthusiast in the pack." He was rambling again. he always did that when he was nervous.
Derek just snorted and said, "Stiles I'm not a star wars 'enthusiast' (he is) but seriously? Princess Leia?? Of all the characters? Why not Obi Wan or yoda?"
"Because Obi Wan or Yoda aren't going to help me get laid tonight." he replied, blushing slightly.
Derek just crooked an eyebrow up at him and got out of the Camaro. "Come on, Stiles, the pack is waiting."
After they all got into the club, the pack dispersed their seperate ways. Scott, Allison, and Isaac went to the dance floor while the rest either sat down or went to the bar.
An hour or so had passed when Derek, who was posted up at the bar, saw Stiles stumble onto the dancefloor with some random guy. The guy was all over Stiles; grinding on him from behind. The two were basically fucking with clothes on. The wolf inside Derek howled out in rage. Derek knows he should turn away and gather what little but of control he has left, but he can't bring himself to. The way Stiles moved and swayed to the music was simply hypnotic. He reached back and looped his arms around the other guy's neck and tossed his head back with a smile. Derek was getting more jealous by the minute. He wanted Stiles to use HIM as a pole to dance and grind against. He just wanted Stiles. 'but you're too much of a coward to take what's yours' says a voice in the back of his mind. With a growl, Derek finally turned away from the dance floor and tried, to no avail, to drown his misery in alcohol. He decides to tune into what's going on with the rest of the pack. That's when he hears it. The voice of the guy Stiles was with.
"You don't know how fucking hot you look" the voice whispered into Stiles' ear, his hands on his hips. "I'm gonna take your sexyass home with me and fuck your perfect mouth and ass, till you scream my name.'"
Rage flooded Derek's senses and before he knew it, he was on the dancefloor, grabbing the stranger by his neck and lifting him up.
"Mine" he growled into the man's face, showing his fangs. He then dropped the man into the floor and yanked Stiles up and over his shoulder and practically ran out of the club.
"Derek what the actual FUCK?!" Stiles screamed while trying to remove himself from the werewolve's grip. "Put me the fuck down! NOW!" But Derek ignored him until he got back to his car and shoved Stiles in the passenger side and then got in the driver's side.
He took several deep breaths to calm himself and shift back to human before he started to speak. Stiles started before him.
"Derek...Derek what the hell was that?" he spoke softly but he wasn't afraid.
"H-he tried to take you. In front of me. I heard what he said Stiles. He shouldn't have tried to-"
"woah woah woah sourwolf I wasn't even going to go home with that guy. I can take care of myself, Derek. It's not like we're together or anything. You don't have to protect me. I'm not even a real part of the pack like Scott and the others, I'm just a human, you don't have to watch over me like that." Stiles interuppted, his scent was angry and stubborn...but something else too...sadness?
"I-I'm sorry.. I shouldn't have done that. I just--"
"just what Derek? Is there something you need to tell me?" Stiles asked softly, the anger was gone from his scent and was replaced by...hopefulness? Derek looked over and met eyes with Stiles. Those beautiful, honey brown eyes stared back with an intensity that sent chils down Derek's spine. Yeah, that was definetly hope in his scent.
Derek, being that he was not good with words when it came to...anything really, but especially emotions, did the only rational thing his brain could think of.
He leaned over and kissed Stiles. Unsure at first, but then Stiles responded by kissing back, and the kiss became more passionate. When Derek breaks the kiss he holds Stiles' face in his hands, their foreheads touching, and breathes, "mine"
To Be Contined.
