A/N: I feel like I will probably be posting a lot of post-eps/episode insert type things this year, so I'm just going to keep them all here, in one place. Easier for everyone I think and tbh less pressure because I don't feel like they all have to stand all on their own. Some will be short, some will be long, some will be fluff, some will be dirty business. Just gonna kind of go with whatever I'm feelin'. So yeah, WATCH THIS SPACE. (I'm not going to cross post these on LJ either, so if you usually read there, BE AWARE.)

murder, he wrote

She's doing it again.

Moving her legs, squeezing her thighs together. Staring at him. Her face is painted in barely concealed want, and it looks good on her, looks really good on her. Would look better on him, but they're in the middle of someone else's precinct and even though they've been outed, he's not allowed to touch her here.

Cruel, cruel jokes.

So they solve crime, as they do. Keep their hands to themselves in public, mostly. Toe the line in private, until he's on the phone and she starts doing it again, undressing him with her hazy eyes, legs traitorous as she sucks on the tip of her own finger. He finally advances on her then, the chirping in his ear almost white noise as he trails a thumb down the fabric of her dress at her thigh, bringing her gaze up to his face.

She's being quiet, knows he's on the phone with the boys, but her eyes are bright and the only thing he sees in them is please not no, and so he skims his hand under the hem of her dress and just feels her tense against him, squeezing those runners legs against each other, fanning the spark of arousal he sees at the edges of her irises.

He doesn't move to touch her further, just lets his fingers span her, grasping, feeling. The phone at his ear tilts upward so the mouthpiece is up and away, out of hearing distance he hopes. She'll kill him if the boys hear her, no matter how much she may want this.

"Does it feel good when you do that?" he whispers to her, close enough that their noses are brushing. He doesn't kiss her though, just watches her eyes as she tilts her hips forward more obviously, crossing her legs harder.

"It doesn't suck."

"You've been doing it all day."

"Well, someone would rather work this case than do it for me, so." She shrugs, her unbothered façade well practiced, but she's let him so far in now, it's barely even worth trying. He sees right through her.

An apology slides through his lips as he presses them against her cheek, breathing her in through his nose as he lets his hand slide higher up her thigh. She tenses against the wall, back pressing harder as she grips her wine glass, but then Ryan's voice is calling his name through the receiver, making them both jump.

"Yeah, I'm here," Castle says, and then flips the phone up again, pressing his body into Beckett's, watching her gasp at the contact.

"Castle, stop," she whispers harshly, eyes cutting to the phone in his hand.

As much as he wants to do this, her job is not a joke, so he just holds her there until Ryan's done talking, then hangs up swiftly and shoves his phone into his pocket.

"What did he say?" she asks, taking a sip of wine from her glass, arm brushing his chest because of how closely they are standing. He can feel her legs tensing again, and he's not sure if she's doing it on purpose or if she's just that desperate for friction, but in either case he's done putting her second for this case tonight.

"Not important."

"Castle."

"This is supposed to be your vacation and I'm ruining it, let me make it up to you?"

He kisses her swiftly, but she pulls away, groaning softly.

"Castle, you're not ruining anything." She's rolling her eyes in that way she does when she's dropping pretenses, like he should know whatever it is she's about to say. "I like watching you do this, fight for the truth." A pause hangs in the air as she lets that sink in for a moment, and then she brings her mouth to his, brushing a feather light kiss to his lips. "I like watching you do what I've taught you."

If her objective was to incite him to solve crime, go back to the case, she spectacularly succeeds and fails all at the same time, his affection for her, for what they do together slamming through him all at once. He wants find every truth with her.

"So does that make you my super hot teacher?" he growls into her ear, both palms now sliding up under her dress to grab at the backs of her thighs, hoisting her up so she can wrap her legs around his waist. She squeezes them against his sides, an echo of what started this all, laughs at the brightness in his eyes.

"Whatever does it for you, Castle."

"You do it for me."

"Show me."

Crime waits until morning.
