A/N: I've never wrote James and Lily before but this was my response to the prompt Jily + 'Is there a reason you're naked in my bed?' that everythingthelight-touches sent me on tumblr! It's short, but I hope you enjoy!

disclaimer: will they really hunt me down if i don't add this part tho

"Is there a reason you're naked in my bed?" Lily asks, her perfect eyebrows raised expectantly.

"Last time I checked, this was our bed, Evans." He smiles at her and winks suggestively.

Lily rolls her eyes at his pathetic attempt at flirting. "That still doesn't answer my question, Potter."

James props himself up on his elbows and lets the cover slide down to his waist. Lily's eyes are drawn almost inexplicably to the expanse of skin he's revealed, before promptly darting back up to his face, where a wicked grin already rests on his lips. "Like what you see?" he asks in that infuriatingly endearing tone that indicates the complete lack of innocence behind the words.

Lily pretends to ponder this, "Oh, you know I do; it's our guests I'm worried about."

This catches his attention. His eyes narrow suspiciously, although the smirk is still prominent. "Guests?" he questions, sceptical.

She nods, "Yep. We're having Sirius, Remus, and Bathilda round for Harry's birthday. Peter couldn't make it but he sends his regards."

"That… that was today?" James asks, and his face pales.

For the first time since the start of their conversation, Lily feels a twinge of annoyance, "When did you think it was?"

"Maybe on his actual birthday?" He says it as if it were obvious, and Lily supposes it is. Birthday parties were supposed to happen on the date of birth, were they not? And maybe Harry's would have done, if their circumstances were a little more normal. But they weren't normal circumstances by anyone's standards, and James' comment only served to remind her of the position they were in, the constant state of uncertainty that hung over their shoulders.

"It was going to be," she began in a curt tone, a sudden mix of frustration and sadness battling for dominance in her voice, "But we had to change it. We don't know what our situation is going to be then."

She's honestly finding it hard to keep up with all the extra security measures herself, but she can't help the bitterness she feels towards him for forgetting. Maybe it's unreasonable, but she didn't want to have to think about their less than convenient predicament. Not today.

So it's with a detached sort of anger that she says, "I did tell you."

James is quiet for a second. "Fuck. Lils, I'm so sorry, I completely forgot about it. I'll be down in a second, I promise."

Lily doesn't exactly smile, but she doesn't exactly not smile either, "You might want to put some clothes on first."

James looks down at himself, and when he looks up again, the smirk is back. "Nah, I think I'm good like this."

"Oh, well that's a relief," Lily says with an exaggerated sigh, "Seeing as I told everyone to come up and use this room to store their coats." Immediately, his eyes flicker to the doorway, and now Lily really does smile. "I'd rethink your stance on getting dressed if I were you."
