"Hey, you're boyfriend is talking to my not boyfriend," informed Lydia dancing over to him with two red cups that probably contained some of the more expensive alcohol that Lydia kept hidden away from the masses.

Stiles said, "Well I suppose they are the only two people of a similar age here and he's not my boyfriend, I don't think."

"You didn't talk about it after you kissed?"

"No, he just kind of left," replied Stiles, "And he hasn't really talked to me since he got here, he just said hello and then I didn't see him."

Lydia suggested, "Maybe he feels awkward, come on, let's go over there. Wait, let's fix you first."

"Fix me?" He looked slightly offended.

Lydia ignored him and buttoned up his plaid shirt that was currently open over a t-shirt with a dorky slogan on. Then Lydia messed up his hair to give him what she informed was "sex hair".

"It's an improvement," she decided after examining her work.

Without waiting for a response, Lydia dragged Stiles off to where Derek and Parrish were talking. It had unsettled some people to see that Parrish was here considering pretty much everyone there was underage and drinking, but then they remembered that he was Lydia Martin's boyfriend. Hopefully he wouldn't arrest people at his girlfriend's party.

"Hi guys," sang Lydia, marching over with Stiles reluctantly in tow.

It wasn't that he didn't want to talk to Derek, he always wanted to talk to Derek, but Stiles was dreading that Derek regretted what had happened between them yesterday. That he would tell him it had meant nothing or that he'd decided Stiles was too young.

Lydia and Jordan started chatting and teasing each other until she finally suggested that they go find him another drink, leaving the two boys alone.

Nobody spoke for ages.

"Are you having a good time?" asked Stiles finally breaking the silence, wishing he'd drunk more so he felt a bit more confident.

"Yeah, Jordan's nice, is he dating Lydia?" wondered Derek.

Stiles blushed because questions about dating but then replied, "No, well they're half dating, we think he's probably been waiting till she's 18, which is now, so hopefully something will happen tonight since Lydia hasn't really liked anyone since Jackson, and Jackson was a dick to her, I don't really know why she was so in love with him, but now she likes Parrish which is good because he's nice. I hope he asks her tonight, she's been waiting for him to for a while."

He was babbling again and Derek was smiling at him, "Well I hope he gets his shit together and makes his move."

Stiles wasn't sure if he was still talking about Parrish and Lydia. "Yeah, me too, I just hope that he tells Lydia what he actual wants to happen once he's made his move."

"Yeah, I can see why that could help avoid confusion," said Derek then he paused, took deep breath and asked, "Do you want to go out for dinner tomorrow?"

"On a date?"

Derek nodded, his ears turning an interesting shade of red. Stiles found him so adorable he just wanted to kiss him right there but he was trying to play it cool so he resisted.

"Yes, I would really like to go to dinner with you," grinned Stiles.

Derek beamed, "Good, that's good, I'm glad, can I have your number?"

Stiles gave him his number and Derek called him immediately so Stiles could have his, grinning when he heard the buzzing in Stiles pocket.

Somewhere a sudden burst or courage came over him, he suggested, "Let's go dance." Wandering over to where a mixture of their friends were dancing. He spotted Kira and Allison dancing together and Cora and Jackson were too. He worried what Derek would think about Cora and Jackson but was happy to see the two girls getting along.

Derek didn't seem to be hugely excited by dancing but he swayed next to Stiles who was getting very into the Taylor Swift song that was playing.

After a few songs Stiles decided to get another drink and Derek followed him, then the two went outside to get some air. It was surprisingly empty in the back garden, so the two sat down to talk.

The talking turned more into kissing, lots of kissing, until Lydia and Jordan stumbled outside and interrupted them.

"I told you buttoning up the shirt would work," she teased.

The two boys were blushing quite a bit.

"Did turning 18 work for you then?" asked Stiles noticing for the first time that Lydia and Parrish were holding hands.

Lydia laughed and said, "Yes, it did."

"Good," grinned Stiles, taking Derek's hand he said, "Come on, let's go inside and leave these two too it."
