AN- It has happened. This fic is over. It's been fun and I'll miss you guys, but you can always jump over to Sheep Suit if you miss my admittedly bad writing of our two favorite boys.

I wanted to save this one for last, because I know I get a mix of D'awww feelings and turned on when I think of Jealous!Derek. Or jealous!Stiles. Or, oh God, both of them jealous.

So, here you go. I love you all and thanks for staying with me. (And watch out, because I might be posting a deleted scene from Gluttony as a oneshot sometime.)

So here is a mix of smut and fluff for you guys. Thank you for being so fabulous!

Disclaimer- I own nothing but a startling new obsession for Sterek fics with Derek as Scott's older brother.

Jealousy

Derek has been jealous before.

A lot of times, actually.

He gets jealous every time Stiles rejects him for a date because he has plans with Scott.

He gets jealous anytime someone checks out/flirts with Stiles.

He gets jealous anytime he thinks someone is checking out/flirting with Stiles.

He gets jealous when Stiles even comes near a porn site- but seriously, why does he do that when Derek has told him multiple times he is up for it at any time?

He gets really jealous when he sees Stiles check someone out or say someone is hot. It's usually an actor/actress, but that doesn't matter. In Derek's mind, Stiles should only find him hot.

But, right now he had a totally legitimate reason for being jealous.

Namely, the asshole that wouldn't leave his boyfriend alone.

He had come to pick Stiles up for school when he saw him talking to some guy in a lacrosse uniform. At first he had thought it was Scott, but he saw Scott walk off with Allison.

So, he walked closer to Stiles and the boy and decided to listen in. At first, they had just been chatting and Derek decided to let them finish. And that's when the idiot started flirting with Stiles.

He was trying to impress him; anybody who wasn't as painfully oblivious as Stiles could see that. But Stiles was just grinning like an idiot and talking about the most random things to cross his mind.

Then, the asshat- asshat? Derek was really running out of insults- asked him out. Stiles had finally realized what was going on and politely refused. But the jock didn't take notice and just kept at it, ignoring Stiles rejections and excuses.

And now, Derek had to step in.

Because this dumbass had put his hands on Stiles. And he'd be damned if he was going to stand by while that happened.

"I believe he said no," Derek growled, walking into full view and taking the boy's hands off Stiles' shoulders. Stiles looked up at him with wide eyes and swallowed audibly. He knew how possessive the wolf could get.

"I believe I wasn't talking to you," the jock mocked, cocking an eyebrow. "Me and my buddy here were just having a conversation."

"Really? Because it seemed to me that your buddy here was rejecting you repeatedly as you desperately tried to hook up with him. When he is clearly taken," Derek allowed himself to grace the douchebag with a grin before shooting a pointed look at a prominent hickies on Stiles' neck.

"Taken?" The jerk- it said Jones on his jersey- asked incredulously. "By who? You? Trust me, he could do much better." The cocky smirk on Jones' face insinuated that he meant himself.

Now, Derek knew he shouldn't be punching underage boy, - he also shouldn't be sleeping with them, but that's a whole different matter- he really does. But he figured this guy is on the lacrosse team, so he's probably used to black eyes anyway.

"Derek!" Stiles shrieked when he saw the dark-haired man wind up and punch his teammate. In one blow, the boy is on the ground, his nose bleeding profusely.

Derek just took Stiles' hand and lead him to the Camaro, ignoring the boy's cries.

"I'll sue!" They heard as they closed the car doors. Stiles turned to Derek with a raised eyebrow.

"I could've taken care of him myself, just so you know." He raised his chin and Derek huffed.

"Oh, yeah, 'cause you were doing such a good job." He's practically growling and Stiles is immediately reminded of back when their relationship had been purely physical, when he hadn't seen the kind and romantic side of Derek. Back to that day in the Hale House when he had accidentally- or maybe not so accidentally, he is still investigating the matter of Derek maybe setting that event up- walked in on Derek shirtless and sweaty and sexy.

And it was a lot easier back then, Stiles will admit. Sex is easier than feelings. He knows all about sex. He understands sex. But when you throw feelings and romance and love and shit in… well, it just got complicated.

But then, there were those times when Stiles wanted the complicated. When Derek showed up at his door with curly fries and the Doctor Who box set and sat with him and watched the whole thing- even though he said he doesn't get British humor and that 'that blonde chick wasn't even that hot'. When Derek is cuddling him and they're both tired, so he starts saying things he would never ever say otherwise. When Derek is asleep and he snuggles up against Stiles and murmurs words like Stiles and love. It was times like those when Stiles craved the complicated.

But, with the good times, comes the bad, and just as much as they laughed and loved- uh, he means liked- they fought, too. Over tiny stuff and then not so tiny stuff. And it was then that Stiles had to remember all the good times they had and forgive Derek for whatever stupid thing he did that time- because it was always Derek who made the mistake. Always.

Derek letting out a loud breath of air pulled Stiles from his thoughts. He looked over and studied the older man's profile, tracing an imaginary finger over each of his perfect features. Around those beautiful almond-shaped green eyes. Then, down to his slightly prominent nose. He trailed over his thin lips and ran his imaginary finger across the slight stubble below it. This man was like a model.

"Are you glaring, gazing, or eye-fucking? I can't tell," Derek said, not taking his eyes off the road. Stiles smiled down at his lap.

"None of the above. I'm just staring. Appreciating."

"Appreciating?' Derek asked with a cocked eyebrow. The corner of his lips quirked up into a half-smile.

"Yes. Not everyone gets to stare at someone as pretty as you without being arrested or just plain creepy. I'm appreciating what I have."

"What you have? You say it like I belong to you." Derek rolled his eyes and Stiles couldn't help the grin that overtook his face.

"Don't you?" He asked, tilting his head playfully. Derek shot him a look but didn't deny it and that made Stiles stupidly happy.

"Where are we going?" Stiles asked suddenly, looking out his window. He didn't know this route.

"Somewhere special," Derek grinned. Stiles rolled his amber-colored eyes at the older man but could feel himself getting excited.

"Derek?"

"Mhm?" Derek kept his eyes on the road, knowing if he looked over at the short-haired boy, he would want to pull over and take him right there. Claim what was rightfully his.

"Are you mad at me?" Stiles became painfully aware of how childish and pathetic that sounded and rushed to continue. "Like, for that douche-nozzle who was hitting on me? Because, I totally wasn't flirting back, I swear."

Derek raised an eyebrow. "Douche-nozzle?" Stiles simply shrugged. "I know. I was there for a little while. You were just being your usual oblivious self. I trust you, Stiles. I know you couldn't ever cheat on me. Doesn't stop me from being pissed at that…douche-nozzle, though. Idiot," Derek growled the last part. Stiles chuckled at him.

"Someone has green eyes," he said in a sing-song voice. Derek turned to him with a confused look, momentarily forgetting his rule.

"I do have green eyes," he deadpanned, scrunching up his face.

Stiles rolled his eyes. "I mean you're jealous. Haven't you ever heard of the green eyes of jealousy?" Derek's face stayed blank. "The jealousy monster or whatever? God, Derek. Did you even have a childhood?"

This time it was the wolf that rolled his eyes.

"We're here," he said finally. Stiles looked out his window and sees woods.

"Are you taking me out here to, like, pee on me? Claim your territory?" Stiles wrinkled his nose but got out. Derek let out an annoyed-sounding deep breath before leading the way.

"Derek. Where are we going?" Stiles whined, tripping over various sticks and rocks as he attempted to maneuver his gangly limbs through the woods.

"We'll be there in a moment," Derek answered, secretly grinning at the pout the younger boy shoots him.

They walked for a couple more minutes before Derek stopped abruptly. Stiles bumped into him and was about to yell before he saw where Derek had taken him. He took a sharp intake of breath, a gasp caught in his throat.

"What is…Where are we?" He asked quietly, looking around. There was a cave to the side and a large pond in front of them. It looked peaceful and beautiful.

Derek simply shrugged, staring at Stiles, watching his expressive face change. "Nowhere. It's just somewhere Laura and I used to go to when things get to be too much." There was only a small hint of sadness in his voice. Stiles looked over to him with wide eyes.

"Then why am I here?" He wondered idly if Derek can hear his heartbeat because it is pounding at a rapid beat.

"Because I wanted to share it with you. You're the only person who has been here other than Laura or me. Laura would've been happy you're the first; she would have loved you." He walked over and sat down near the pond. Stiles stared after him, and he really wasn't going to say anything. But he couldn't take it.

"God dammit, Derek!" He yelled and the older man spun around, looking alarmed. "You can't do that!"

"Do what?" Derek asks, wrinkling his nose in confusion and all Stiles wants is to kiss him.

"Stop doing that! Saying sweet stuff like that and acting like it's nothing. You can't tell me that your dead sister would approve of me and that I'm the only one you've ever brought here and then turn around like it is nothing. You just can't. There's something behind that. Some kind of feeling. Some kind of something that you can't just play off. It isn't fair." Derek looked appalled by Stiles' outburst.

"Stiles…" He got up and walked over to the boy, lifting a hand up to cradle his cheek. "I…I'm sorry. I didn't know it was such a big deal. I was just… saying how I feel."

"Yeah, well, next time give me a warning or something. I get that you are uneducated in emotions, but you can't talk about stuff like that the same way you'd chat about the weather."

"Here's a warning," Derek said, leaning closer until he was quite literally stealing the air from Stiles' lungs. "Stiles, you are the most important part of my life right now. Shit, you are my life right now. When all the werewolf stuff starts to be too much, I remind myself of you and I'm okay. I'm okay, because I know I can climb into your bed, into your arms. You bring me down from the edge. You're like home. You're… You're my heaven." And fuck, Stiles just wanted to have him right then and there. But this is a breakthrough and if Stiles just attacked him with his mouth, it probably wouldn't lead anywhere.

"Derek… you're my heaven, too. When I'm with you, I forget about all the shit that is our lives. Which is pretty crazy, considering you're the main focal point of that shit. But, it's true. And, I…" Stiles had to stop there, because if he continued, he might say something bad, very, very bad.

But Derek surprised him by sweeping down and pressing his lips against Stiles' own. He came back up- way too soon- with a grin. Leaning his forehead against Stiles', he whispered, "I love you, too."

And Stiles understands. He understands those movies and songs and books. He understands why Scott can't go two seconds without touching Allison or talking about her if she isn't there. He finally understands what is so great about love.

"I love you," Stiles said back, grinning like an idiot. "I love you," he murmured into the crook of Derek's neck. "I love you," he breathed into Derek's ear. Kissing Derek, he mouthed the words into the man's lips.

Derek pulled them down so they were lying down on the soft grass, Stiles straddling him. He moved his lips down to the pale boy's neck, sucking and licking. Mewls of pleasure encouraged him.

"Derek…" Stiles said when Derek started to remove clothing. "I am not having sex with you where you and your sister used to go when you were little. No." He pressed on, even when his voice faltered for a moment at Derek grinding his hips into him.

"We never went over on the other side of the pond." Stiles glared at him. "I'm being serious! Laura was always worried that I would drown."

Stiles didn't want to do it. Really. But what was he supposed to do when his much larger, much stronger werewolf boyfriend lifted him up and carried him over to the other side?

As soon as they were over there, Derek quite literally attacked him with kisses, open-mouthed and sensual. He slowly peeled off Stiles' shirt and moved his lips down his chest, stopping to pay special attention to each and every mole and freckle.

"God, Derek," Stiles groaned, already feeling himself get hard. He cursed lowly as Derek got to his jeans, slowly pulling them down his legs.

"No," Stiles said when Derek went for his boxer-briefs. "You don't get to take off my underwear until you have something off. I feel way too exposed right now."

Derek growled but quickly ripped off his clothes.

"There. Happy?" He grumbled against the boy's lips, tearing his underwear off.

"Very," Stiles grinned. He got into their usual position before Derek stopped him.

"No. I want to see you." He pulled Stiles onto his lap. This wasn't fucking; this was love-making.

He didn't have lube with him, so he moistened his fingers with his own spit and pre-cum. Stiles was a mix of disgusted and painfully turned on.

Mostly turned on.

Derek nudged his entrance, warning him that he was about to ready him. He stuck his finger in and Stiles noticed that it barely even hurt anymore. Just felt really good.

Soon, there was another finger in, scissoring until he was sure he was ready. When the fingers were removed, Stiles let out an unintentional whine. But he was fine as soon as he felt Derek line up at his entrance.

His eyes caught Derek's and he smiled as Derek slowly thrust in. A rush of pleasure exploded through him and he took a deep breath to steady himself. Derek's forest green eyes stayed on him as he sped up his pace.

Stiles couldn't help the low moan that erupted from him. "God dammit, Derek, faster. Harder." Derek complied, panting. He reached up and pulled Stiles into a kiss.

"Stiles," he groaned against the boy's lips. He reached across and fisted Stiles' dick, pumping in time as he thrusted. Stiles gasped and flailed slightly, whimpering.

"Derek, I swear to God, if you don't stop that, I am going to come right now," he warned. Derek grinned, but didn't let up.

"Derek," Stiles sighed slightly. "I love you. I love you, I love you, IloveyouIloveyouIloveyou." Derek pushed in harder at each word until Stiles could feel that he was close.

"Der…" The rest of the word was cut off in a gasp. He closed his eyes in ecstasy only to have Derek open them again. He stared into familiar green eyes as he comes, yelling Derek's name to the world.

Derek follows shortly after, kissing Stiles' neck. He bites down slightly as he explodes, but Stiles decided not to tell him. He liked the idea of a lovemark, of everyone knowing he belonged to Derek.

He would have to remember to leave a mark on Derek next time so those ladies at the grocery store would stop eyeing him like a piece of meat.

He rolled off of Derek, but kept close, cuddling into his hard side. He smiled lazily up at his lover, his boyfriend, his soul mate. He never realized how lovely that word was.

"Derek?"

"Mhm?" Derek mumbled sleepily into his hair.

"That first time…that we, you know. Well, was it on purpose? You never answered me." He felt a grin curl against his forehead.

"It was," the older man admitted. "At first, it wasn't. I really was just inviting you over to teach you some tips. But when you got over here, and you stood there watching me like that, I could smell- I could feel your arousal. It was too much. So, after that, I might have tried to…"

"Seduce me?" The teen teases, grinning. He remembered Derek flirting with him. "You're terrible at it."

"Hey," Derek says, sounding just the tiniest bit offended. "That's funny, because I remember you all over me in less than ten minutes." Stiles grinned sheepishly.

"I love you," he said one last time, just to hear the words again. He loved him. He loved Derek Hale, possessive Alpha, head of the grump club, resident Sourwolf. He loved him and he loved Stiles back.

"I love you, too," Derek whispered against his head. The younger boy sighed contently at the words.

He could certainly get used to that.

The End.
