Kate woke up startled by a loud bark of a dog. She had no idea where it could've come from, she had no dogs, and last thing she remembered, she was in her apartment. Oh my God! The fear ran through her spine as she started to stand up. That's when she realized she was naked. She held the blanket loosely in front of her body right when the dog barked again. And she found it. It was Bubbles, the neighbor's lab, right by her door. Her open front door.
"Bubbles!" called the old Mr. Reynolds, and she muttered a 'crap', hiding behind her couch.
'Detective Beckett?' he called into the house. She then came out of her hiding place to ensure he wouldn't call the police or whatever.
"Good Morning, Mr. Reynolds!" she said, trying to sound as natural as she could, being the naked lady talking to her neighbor about the door open overnight.
'Kate, dear, is everything alright?" he asked, looking genuinely worried, holding his dog. That's when the noise of a flush came from the bathroom, and the old man understood. He held the doorknob and, trying not to laugh, started to close it. "I'll just close it for you, dear."
"Thank you!" she screamed as he was closing the door, red as a strawberry.
Castle came out of the bathroom just after that, and she rushed towards him, slapping his chest. "The door was open! How come you didn't see the door open? My neighbor…"
"Oh, wow! Stop it! I just went to pee, and was still sleepy! Not my fault!" She was still slapping him, now a little more like caressing him.
"So, the door was open all this time, hun?" He laughed, and she put her head against his chest, muttering a crying sound, desperate in shame.
"I've got a reputation with my neighbors, you know?"
"I'm sure you do, my dear. And you've just improved it!"
She now punched him lightly on the shoulder, while he kissed the back of her head, still laughing. He then cupped his hands under her chin, pulling her head up to meet his eyes.
"Good morning, my love" he said, clearly trying to put the neighbor incident behind. She smiled, and replied. "Good morning", and they kissed. The taste of him in her mouth, his shape on her touch was still something that Kate couldn't believe it was happening. She laced her fingers behind him, locking her arms around his waist, and pulled him closer, eager for more. He gently pulled her up to carry her to the improvised bed of blankets and cushions on the carpet. He put her on the floor slowly and even more gently lied on top of her. She moaned under her breath as he went down to kiss her breasts, caressing the back of his head and reaching to kiss his forehead. He kissed her on the lips and said, breaking the moment with a silly humour.
"We could open the door, if you like".
