Prompt: Castle wakes Kate by eating her out.

Kate always kicked the covers off in her sleep, something Castle had learned very early on in their relationship.

Because of this fact, they always had to redress after sex while they were at the loft; there was no telling who would barge into his (now their) bedroom without knocking first. It was such a shame, too, because he loved feeling her naked skin against his, their mutual heat keeping them warm even when she kicked off those covers.

Which was why he loved when they went to the house in the Hamptons, just the two of them. With Alexis in school and Martha too busy with her acting school to accompany them (which, as much as he loved his mother, he was happy about), they had then entire house to themselves over Kate's long weekend, a rare three days off in a row.

Castle woke before Kate their first morning there, warm rays of sunlight already filtering through the cracks in the curtains. They offered more than enough light for him to clearly see Kate, naked and sound asleep, lying on her back, one knee bent and her head slightly turned away from him. They always started off spooning, but throughout the night, they moved, Kate usually ending up on her back, Castle on his stomach next to her. But they always kept contact in some way. When Castle woke that morning, his arm was slung across her torso, just below her breasts. And, of course, she'd kicked the covers off during the night. They lay abandoned and forgotten at the foot of the bed.

He shifted onto his side, careful not to wake her, and lifted himself on his elbow as he looked down at her. The steady rise and fall of her breasts with each breath she took let him know she was still sound asleep. He thought her the most beautiful when she was sleeping. She was always gorgeous, of course, but sleeping, she was relaxed without a care in the world, her sleep-flushed skin a rosy hue that gave her an innocent appearance.

Castle grinned. There was absolutely nothing 'innocent' about Kate Beckett. Not when it came to sex, at least.

Memories of the previous evening fluttered through his head, sparking his arousal. He felt his groin stir in response. Feeling uninhibited by the-wine-that-made-her-all and the fact that they were alone, really alone, they were even more adventurous than normal. And normal for them was pretty damn adventurous!

Castle groaned softly as he remembered Kate eagerly bending herself over the back of the couch and demanding that he take her from behind. He remembered her pulling out the ice cubes and using that damned talented tongue on him until he literally saw stars. He remembered her pushing him onto his back and straddling his face as he worked her with his mouth and tongue.

That memory, the taste of her on his tongue, gave him an idea as he recalled a conversation they'd had weeks before. While discussing various fantasies, Kate had revealed that she wanted to be awakened by him going down on her. He'd been looking for a chance to do just that, but hadn't had the opportunity because of the stupid having to wear clothing to bed thing. It's not like he could take off her pants without waking her.

Moving carefully so he didn't wake her, he reached out and gripped her smooth thighs gently, pushing them apart. She stirred slightly and he stilled, holding his breath. But she didn't awaken, just murmured a few unintelligible syllables before relaxing once more, breathing remaining steady.

He let out the breath he'd been holding and continued on his mission. He settled his shoulders between her thighs, breathing in her scent before pressing his lips to the crease where her thigh met her torso.

Kate let out a slight whimper and he looked up, but she was definitely still sleeping. Knowing he was probably fueling a sex dream (that hopefully stared him, he thought), he continued with renewed vigor.

He parted her folds and lapped greedily, surprised and pleased to find her already beginning to become slick with arousal. He circled her clit with the tip of his tongue, encouraging her body to give off more lubrication so he could slide his fingers inside her.

He tested her opening with the tip of one finger, finding it adequately slick enough to slide inside her and start a slow, steady rhythm in and out, all the while keeping up his attention on her clit with his tongue.

He could pinpoint the exact moment when she woke up and became fully aware of what was happening; her breathing suddenly became erratic, her thigh muscles tightening around his head. Seconds later, her fingers threaded through his hair and she began making those choppy, breathy moans and whimpers she made ringing in his ears.

"Castle," she groaned suddenly, hips pressing forwards, nearly dislodging his lips. He reached up and pressed a hand to her abdomen, holding her in place against the pillow top mattress. He added a second finger, increasing his pace and force.

Kate gasped, fully awake now. She gripped the 400 thread count pillowcase near her head with her free hand, her fingers twisting in the cream colored cotton. Her breathing was shallow and ragged, laced with guttural sounds that conveyed her imminent climax.

He continued devouring her, reveling in the unique, exquisite taste of her, the salty sweetness coating his tongue and lips. He felt her thighs and abdominal muscles tense up and she sobbed her release, calling out his name over and over. Her inner muscles gripping his fingers in a heated, pulsing vise.

He never slowed his attentions as she rode out her orgasm, back arching off the bed, heels digging into the mattress. He kept nipping and lapping at her wetness as she came down slowly from her high, her breathing harsh and uneven, her entire body quaking with aftershocks.

Kate forced her fingers to relax, releasing the pillow case and allowing blood flow once more. Her eyes remained closed as she focused on catching her breath.

Castle finally eased his fingers out of her, earning a small groan of protest from Kate. He grinned against her stomach as he kissed his way up her torso.

She opened her eyes when he reached her face and pulled him in for a kiss. She loved that could taste herself as their tongues met and danced.

"Good morning," Castle murmured when they parted several minutes later.

"It certainly is," Kate responded, her hands rubbing against his early morning stubble. She pushed against his shoulder until he rolled off her onto his back. She settled over him and kissed along his jaw, then down his torso. "Let me show you how good it can be."

Oh, yes, Castle thought. He definitely liked when they were alone and had no need to wear clothing to bed. Maybe he'd invest on a lock for their bedroom door when they returned to the city.

Kate did that thing with her tongue.

Definitely investing in that lock. As soon as they got back.
