Early Caskett.
When they got into the elevator, he pulled her close. It had been a long day, and all they both wanted was to be home. Beckett cupped his cheeks, placing two, little kisses on his lips. She gave him a small smile before resting her head on his shoulder.
He turned his head to whisper in her ear. "You okay?"
"Yeah, just tired." She turned her head into his neck, and he kissed her temple gently, silence filling the elevator for the rest of the way down.
They had been home less than half an hour before they were both slumped on the couch, wrapped in each other's arms. Castle ducked his head, letting it rest on top of hers. She had fallen asleep in his lap. He played with a stray curl that fell in her face. He pushed the hair off her forehead, and kissed it softly. He shifted slowly, moving to the edge of the couch, deciding if he should leave her, wake her up, or carry her. But one look at her peaceful face and he decided carrying her to bed was the best option. He scooped her up and walked quietly through the darkness, laying her on her side.
"Castle." She mumbled, caught somewhere between sleep and awareness.
"Go back to sleep, beautiful." He kissed her forehead again, still standing over her.
"Castle." She said again, as he headed to the bathroom.
"Yes?"
"Come cuddle."
A small smile grew on his lips. "Alright." He slipped off his shirt and pants, wearing only his boxers, and slid in next to his girl. He wrapped his arms around her waist, burrowing into her side and the pillow. She snuggled closer, wrapping her arms around his, both falling asleep to the sound of the other's heartbeat.
