Something longer in the works, but since I seem to be posting here now as well, I thought I'd add this to the collection.

Prompt: Castle, "Someone's stalking me", kiss, poker, go fish
He comes up behind her as she's waiting for her coffee to finish dripping through the machine. So close he can feel her body's heat seeping through her clothes, not quite close enough to touch.
"Looks like someone's stalking me." Beckett folds her arms, refusing to give way. "Again."
"Not stalking. Standing. Just waiting my turn."
The not-touching is electric. Castle expects to see blue sparks between them, expects his hair to stand on end. He can hear her breath catching in her throat, feel the tension vibrating in every muscle along her spine. He knows her eyes are half-closed, her lips parted, waiting and not, wanting and not, loving and hating him at the same time.
He's terrible, he knows, but he loves doing this to her.
"I was thinking," he says. 'About this poker rematch you keep promising me since you ate half the gummi bears.'
'Mmm?'
Ooh, beyond speech already. Not bad.
"Texas hold 'em?" He slides one hand across her stomach and pulls her gently back against him. It's actually easier when they're touching like this, full body contact gives the electricity somewhere to go.
He can feel her thighs trembling and for a moment he imagines sliding his hand lower, inside her belt, low enough to slip his fingers between her legs and make her come standing right here, in front of the espresso machine in the precinct house, with Esposito and Ryan and everybody else watching to see how hot Kate Beckett really is.
How very hot and how very his.
"Or maybe you'd prefer Go Fish?" he growls into her ear.
"It's going to be lowball if you don't stop this." Her fierce whisper gets sucked back into her chest as he rocks his hips, letting her feel him against her ass. Barefoot, they don't quite fit, but when she's got shoes on she's almost as tall as he is, which is sexier than he ever could have imagined. There's no bending needed, everything is exactly where he can reach it.
He pulls her closer to trace the edge of her ear with his tongue and feels, rather than hears, her groan of despair. "Of course," he continues, "I've always been pretty good at old-fashioned stud."
He's forgotten how quick she is, forgotten that if everything is in reach for him, it's the same for her: before he gets to the top of her ear he feels her fingers close around his balls, applying a kind of pressure that means castration could be imminent.
"I mean it," she hisses. "Stop, or lose the use of these for the foreseeable future."
"Okay, okay, truce." He drops a kiss into the ticklish part of her neck for revenge before stepping back, out of her reach. He doesn't watch her go, but he can hear her cup rattling against the saucer all the way back to her desk. Meanwhile, Castle makes himself the slowest, sweetest, most perfect cappuccino the world has ever seen and tries not to daydream about how she's going to get him back.
