Ahh I'm sorry! I'd read this the day you posted it and completely forgot to critique it. Sorry for the lateness of my response.
Let's get into the critique! The first thing I noticed is really nit-picky and something that you don't need to worry about that much, but don't!! put!! double punctuation!! Two exclamation points are never, ever necessary. Not a huge deal during a first draft, but still. Other grammatical issues include run-on sentences and dropped commas.
Here's a real, hopefully helpful tip about dialogue –the more you have a character say another character's name, the more stilted your dialogue sounds. Example: You have Lukas say Camie, Camie, and Cam in the first three sentences he says. Listen in on conversations between others. They may call each other's names to gain their attention, or to tease, but beyond that? Not very often.
Building off of the name thing, you also repeat their names a lot in the narrative. Think of it this way: in this scene, there are only two characters. A guy and a girl. Meaning, if you use pronouns "he said" or "she did so and so" it would flow better and retain its clarity.
To be more clear, yours:
“Always.” Camie surrendered half the blanket, but Lukas pulled the rest off of her revealing Camie’s pajamas, an over sized t-shirt and huge sweatpants, which Lukas quickly identified as his.
Lukas raised his eyebrows quizzically. “Um Camie, are you wearing my clothes?”
Camie tugged at the blanket, trying to cover the clothes that were so glaringly Lukas’. “Uh, no?”
“Cam that is not a question you should answer with another question.”
“No, these are definitely mine.” Camie blushed.
Edited version:
"Always." She surrendered half the blanket, but he pulled the rest off of her to reveal her oversized t-shirt and huge sweatpants. Lukas quickly identified them as his.
He raised his eyebrows quizzically. "Um, are you wearing my clothes?"
She tugged at the blanket, trying to cover the clothes that were so glaringly Lukas'. "Uh, no?"
"Cam, that is not a question you should answer with another question."
"No, these are definitely mine." She blushed.
I'm not amazing at critiquing romance/fluff because I don't write it often enough, but from what I can tell, this is really good! Very light and adorable. You've created a very domestic and cute scene that really sets up the characters' relationship. Good job.
