Title: Sterek & McDanno 4 Eva by Merlin_Wolfgang_Trades_Hale

Summary: Stiles is visiting his Uncle Steve in Hawaii and possibly getting a job at Five-0. Derek learns about this and goes to Hawaii in hopes of starting a relationship with Stiles. Stiles wants. But there are some barriers...mostly Steve's protective-papa-bear-ness.

"You might want to cross your legs before you're arrested for public indecency."

Stiles lifted his shades to get a better look at the speaker and smiled when Derek came into focus. He placed his umbrella drink on the side and got up to hug him. As Stiles got up from the pool the water made his trunks heavy and also latch on like a second skin to him. Derek saw many peering eyes and pulled Stiles in a bit closer.

"I have a few connections, I'm not worried about being arrested. Derek! What are you doing here?"

"There were some repairs that needed to be done to my loft so I had to be in Beacon Hills. I ran into Scott and he told me you were visiting family here on the island. I just checked into my room and changed. I caught your scent in the lobby."

"Doesn't answer what you're doing here really." Stiles reminded him.

There had been a spark between them. Always has been. In the beginning, it was buried under all the adrenaline and stress that came with Scott being bitten and them being hurled into the supernatural. After that, it was one thing or another. Age difference, being with different people, questioning their sexuality. The last time they saw each other Stiles had been a few months shy of nine-teen, both of them were single, and they dared to have a single night. But they didn't last. Cora needed Derek's help and Stiles was looking into programs in law enforcement. Part of the reason he was here, aside from visiting his Uncle Steve. With how he's performed in the FBI so far, his uncle Steve thinks he can get him in Five-0. There was still a lot of talking needs to be done and Stiles might have to complete the academy first.

"Well,...you're here. We're away from prying eyes and the supernatural. I hear it's pretty damn romantic. I thought...why not?"

Stiles blushed a bit but didn't hide his smile. He looked at Derek's clothes though. "The tank top's okay but seriously Derek? Black jeans in Hawaii? You'll overheat."

"Why don't you come up to my room and help me decide what I look best in?" There was a heavy flirtation undertone to that and Stiles loved it.

"I am loving this IslandWolf," Stiles said in approval.

Derek did pause for a moment and asked, "What are you doing in a hotel anyway?"

"Hm? Oh, my uncle's partner has a nephew himself. Since we're closer in age we were gonna hang out but he got called into work while we were at the bar. I decided to stay for a bit. The burgers here are expensive as hell but really good."

"So you're not dating, right?" Derek asked. Both hopeful and with a hint of jealousy.

"Not yet. But we'll see how today goes." Stiles replied with a smirk as he leaned up to give Derek a small kiss. "Now...you said something about helping you dress or...undress?"

"Yeah...in my room...penthouse suite." Derek showed off a bit.

Stiles made an impressed face before grabbing Derek's hand and heading back inside.

"Lou, you and Danno go and speak with the manager," Steve said before storming off.

Danny called after him with annoyance. Steve was Steve so when he did things they usually had a reason. Danny was confused for a moment since up until then Steve was more or less well behaved and focused on their latest case. When he saw the direction Steve was heading, something caught his eye. Or rather someone. And then it made sense.

"Oh."

"Oh? What oh? What's wrong with McGarrett? He looks like he's about to kill someone." Lou stated.

"That's because he might. Oh means, oh look over there where Stiles is sitting on an older, buff, model Adonis in really right booty shorts and they're both sucking each other's faces off, oh."

"Oh," Lou replied in understanding. "Think we can hold off in talking to the manager?"

"He's full-on Rambo mode, I think it's our duty to make sure he's not overdoing it, right?"

"Right," Lou smirked and winked at Danny before looking over at Steve.

Stiles was sitting on Derek's lap in the shallow side of the pool near the in-pool bar. After some very passionate fun in Derek's room, they decided to enjoy the Hawaiian weather and hotel pools. Stiles got on Derek's lap when he got one too many looks that made Stiles jealous. Derek's own jealousy wasn't much better with the looks Stiles received and held Stiles closer. Forgetting everyone around them, Stiles straddled Derek's lap and began to kiss him and they've been blissfully and idly making out for just under half an hour.

"Ahem!"

Stiles pulled away from Derek and looked at Steve with wide eyes. "Uncle Steve! W-what are you doing here?"

"I can ask you the same thing." Steve glared at Derek with all his might.

"I asked you first. But if you must know...Eric was called into work, so I was left alone. Until I ran into an old friend."

"Old friend huh?"

"Uh...hi, Derek Hale. Pleased to meet you." Derek lied but tried to smile through.

"I'm sure." Steve deadpanned before grabbing Stiles by the arm and pulling him up.

"Hey!" Stiles protested.

"We're leaving now. Mr. Hale, enjoy your vacation and have a safe trip home." Steve droned as he pulled Stiles along.

Derek shot out of the pool and chased after and grabbed Stiles's other arm. Then he looked eyes with Steve before leaning in to kiss Stiles. "I'll go home when Stiles tells me to go."

"I'm guessing that might prove an expensive trip," Steve commented.

Derek shrugged. "I'll be fine. And Stiles is worth it."

Steve scoffed before pulling Stiles off again. Stiles sent Derek an apologetic glance and mouthed to call him later.

"Hi, Stiles." Danny greeted with a cheeky grin as Steve and Stiles passed them. "Babe, I'm proud of you. You didn't go full Rambo."

"I was tempted. I'm gonna take Stiles home. You guys got it from here?" Steve asked.

Lou gave him the A-OK hand sign, "We got it.

"I'm not a little kid," Stiles complained as they drove home.

"Maybe not. But you're under my care. Living under my roof so you follow my rules."

"So what? I can't date?"

"Sure you can just...he's older than you!"

"So? I like him. I like that he's older. He knows what to do." Stiles said and he knew it was a bit petty and childish, but he was mad at his uncle's behavior. On the plus side, he seemed to have rendered his uncle speechless. But by how white his uncle's knuckles were, he was pretty upset.
