"Castle," Kate said as she walked into his office, wearing a short robe. "When are you coming to bed?"

He didn't look away from his computer, typing away. "Um… just let me finish this chapter."

"How long do you think it's gonna take?" she asked her voice low and husky as she moved behind him to massage his shoulders.

"I don't know. You can't rush the creative process, sweetie. I'll be in as soon as I can."

She rolled her eyes, sliding her hand into his shirt then kissed his neck and cheek before moving to his ear. She nibbled his earlobe then hummed, his earlobe still between her lips, sending a vibration through him that nearly knocked him off his chair.

"Or… or I can just leave this chapter until tomorrow," he stammered, standing up quickly.

She smiled, licking her lips. "Good. I have a surprise." She ran her hand along his chest, pulling gently on his shirt as she began to walk out of the room.

"Oh, did Christmas come early this year?" he asked excitedly as he followed her down the hall.

She smiled at him as she opened the door silently and motioned for him to go in. He stopped quickly, looking at the camera set up on a tripod, angled toward the bed.

"I feel like I'm missing something," he said, looking at the setup.

"Oh, you're not." Kate locked the door then walked over to him. "That film crew in the precinct inspired me," she told him, wrapping her arms around him, slipping on hand into the back pocket of his jeans. "I thought it might be fun to make our own… documentary."

"Oh really?" he asked, putting his arms around her. "Do you have any ideas about what this documentary would be about?"

"Well, I was thinking it could be about this detective and her boyfriend," she began, slowly unbuttoning his shirt. "They have this kind of forbidden romance and have been working so hard."

"So… so hard," Castle agreed, swallowing hard.

"Mmhmm," she hummed, nodding in agreement as she untucked his shirt, pushing it off his shoulders. "And after 12 days of having to keep their hands off each other and working so late, they have all this pent up energy… just begging be released." Her fingers brushed the growing bulge in his jeans and he almost fell over.

"It… it sounds like blockbuster," he said breathlessly.

"Glad you think so." She shoved him gently into the bed and straddled him. She ran her hand down his chest and stomach, unbuckling his belt. "I'm very eager to start production," she told him, untying her robe and letting it drop.

"Oh, you have no idea how eager I am," he told her, looking at her as if he'd never seen her naked before.

"Actually, I do," she said with a giggle.
