I wanted to write an actual full on story for LWD but I couldn't for the life of me figure out what to write it about. So going through Dasey trailers made on youtube, I rewatched a specific one for the millionth time made by LyraGW (who makes amazing videos by the way) with LWD clips to a Grey's Anatomy promo. And bingo! A story idea lightbulb went off over my head. Watch it here:

Dasey. With hints of Shemily and Lizwin.

Takes place in the middle of their Senior year. As usual, since it's a Dasey, Casey and Derek are slightly out of character. I tried my best but nobody's perfect (and why did the words, 'I gotta work it' sound out in my head after that. Too much Disney). It's more from Casey's perspective then Derek's but it still has them both.

Disclaimer: I don't own Life With Derek. It sucks to be Mike Seaterless, but I might come to accept it someday. Might.

"I had sex last night."

"You had WHAT?!" asked a shocked Emily.

"I had sex last night," Casey repeated calmly. "With the wrong person."

"How…wha…why...who?," Emily finally managed to get out.

Casey glanced up, her eyes connecting with a waiter's across the room before quickly looking away. She hadn't planned on telling Emily about what had happened the night before, but as soon as she sat down across from her friend at Smelly Nelly's, she blurted it out.

"Em, everything happened so fast and I'm still not completely sure how it all happened, but it did and now I'm freaking out because I don't know what to say to him or how to act around him, or if I even should react to him! Does he want to ignore it or pretend it didn't happen? Does he want it to happen again? Did he initiate it or did I? I don't know what he wants or what I want, or what to do or think or say or feel. I didn't even know I could feel anything like this for him, not that I know exactly what I feel for him, but I just don't know what to—"

"Casey!" Emily screeched as she stopped Casey's flailing hands by grabbing them in her own. "Calm down! Just stop a second. Take a deep breath. Come on. You can do it."

Casey closed her eyes as she warily inhaled and exhaled, puffing out her cheeks.

"Now, what happened last night?" Emily asked.

Casey opened her eyes slowly and said, "I had sex last night."

Emily laughed lightly. "Yes. We've established that much." She paused before continuing. "Ok I'll go in another direction. Specifics. We'll start with who did you have sex with."

Casey cringed. "Promise you won't get mad?"

"As long as it wasn't with Sheldon, I promise I won't get mad."

Smiling lightly for the first time that morning, Casey shook her head and said, "It wasn't with Sheldon."

"Ok then for the last time I ask, WHO?!"

Looking up Casey suddenly tensed as Derek walked up to their table.

"Can I get you guys anything to drink?" Derek asked avoiding looking at either of them.

Emily, now beyond frustrated, quickly said, "Two waters. Now go away." without looking away from Casey. Derek walked away with a grunt, while muttering, "Jeez never thought I'd miss her being obsessed with me. At least then she was nice."

Realization hit Emily at that moment as she watched Casey nervously watching Derek's retreating form.

"Oh. My. God."

Tell me what you think. You know how it works.
