"I'm sure I'll think of something," Beckett observed, somewhat too nonchalant for Castle not to be suspicious.

She stood in front of him, smirking straight ahead, and then her hand was moving what is she-

Oh.

Oh.

Why Detective Beckett, how very salacious of you.

He didn't know whether to push her away or push her up against the wall; the latter was sounding very tempting, but then again, they were in the precinct elevator—

She squeezed, and he could see the flutter of her eyelashes as she tilted her head sideways, trying to pretend she wasn't watching the play of his facial expressions.

(She was, though. She totally was.)

Beckett pivoted around to face him, her left hand remaining in its… previous position, while her other arm slid around his neck, fingers pulling lightly at the soft hair at his nape.

"I know you can't resist my body," he said, going for 'sexy' but failing miserably as she scratched her nails lightly down the back of his neck and he had to swallow a squeak, "But I don't think right now is really—"

She walked the fingers currently resting on his crotch up and over his hip, around to his back, down a bit. Another squeeze; rougher this time.

Self control, Rick, self control.

"Hmm, Castle?" she purred. Purred. Katherine Beckett was purring at him while feeling him up in an elevator.

"I—I just don't—"

She leaned in, impossible close, and pressed her cheek to his, her breath hot on his ear.

"Hm?"

"Maybe you should just save it… for later?" he managed to stutter out, resisting the urge to touch her.

A stinging nip of teeth on his earlobe.

"Are you sure?" she breathed, this time with a flick of her tongue, oh god oh god her tongue, he knew what that tongue could do, and actually maybe he wasn't sure, he could just press her up against the wall and then-

Ding.

The doors slid open and she stepped casually away from him with a quirk of her eyebrow.

"Oh well; it was your choice." She murmured with a smirk, striding out of the elevator with those long, long legs, and he follows, still stuttering.

This woman is going to be the death of him.
