A/N: Hey hey So I'm back on the map...and writing dasey. :) Woot so because I don't think this fandom has gotten as much credit as it deserves I will be writing quite a bit of Dasey. not sure if it will all go u here though So... lol let me know what you think. ALSO let me know if this should be chaptered or stay as a one-shot cause i can do it either way. :) Enjoy and review.

It was only a kiss. A one-time sure-fire way to alleviate the stress and tension so tangible between them. At least that's what Casey kept telling herself as he forced herself to stay awake and stare at the ceiling. Anything to keep from remembering the feeling of those hot lips on hers, demanding but luring and shit she wasn't supposed to be thinking of it. She had been oh-so-foolish to take his challenge not-quite hidden in his smirking stare. But god how it had stirred butterflies in her stomach.

And he'd been licking his lips just so all night and seemed intent to touch her in some way at all times. Even if that touching meant he'd picked three fights with her already resulting in them tumbling about fighting for whatever mattered that moment. She wasn't one to mention that it was excessive even for them because its one of those things they don't mention. Or think about. EVER.

They'd been drinking together with Emily, Sam, Ralph and Sally. Nora and George were out, Lizzie and Edwin were away at friend's houses and Marti was fast asleep. A forty of vodka and one of rum had all the friends ridiculously smashed…even Casey. Now one might wonder why such a party would occur at all. Four words would pop up had it been asked about. Last weekend in London. And to that Casey had to drink.

Soon however said alcohol was gone and Sam, Emily, Ralph and even Sally had left. Which left two tipsy teens and a shot of rum left. Derek had experience with drinking so his reflexes were far superior to Casey's and he held the shot in his hand. Casey narrowed her eyes as Derek smirked. Time slowed as his hand tilted the shot down and into his mouth.

As soon as he poured the liquid into his mouth Casey pounced, her lips crushing against his siphoning away the rum before he swallowed it all. Which he did before pushing Casey back against the couch as if to hold her closer would burn him. Their lips were fighting, tongues dancing and it was as intoxicating as the burning sensation at the back of their throats.

But it was over all too soon. Both teens backing away terrified, all too aware that they wanted nothing more than to strip and battle it out. Nothing to blame but themselves they crept away in silence cleaning up and dropping off to sleep in anxious exhaustion. Days later, having dealt with the hangover, the party-talk from Nora and George, suspicious comments from Edwin and Lizzie and Marti's cute observations….the sexual tension was building even faster. It was all they could do to keep their minds clear, hands to themselves, mouths firmly to themselves and minds off the subject.

They just weren't supposed to think about this…And that's where Casey supposes she's in trouble because she can't quite figure out how to get Derek out of her head. He's become like some devil-on-the-shoulder figure sent to torment her thoughts with all the delicious things she could be doing with him just one room over. But Casey was a McDonald and Derek was a Venturi. Her STEP-BROTHER…though he'd never been seen as one. Not ever.

A/N: So what did you think? Hope you like it and review. :) remember one-shot or chaptered?
