A/N: Did anyone else really want the "joint custody" to go somewhat differently?

Castle and Beckett had a problem. They both wanted to take care of the dog for the night. Alexis was gone for the weekend; Castle would be lonely by himself. Kate is used to being by herself, but she is thinking about getting a dog and wants to take a trial run. What will they do?

"I have an idea."

"No, Castle, we are not going to switch off like divorced parents with their kids!"

"But I hadn't even—"

"No."

"Awww. Then what are we going to do?" He pouts and gives her a look that he hopes she can't resist. She eyes him skeptically. Then, he had an idea. His pout turned suddenly into a sly grin, and she knew she was in for it.

"What, Castle? What is your grand idea that doesn't involve taking the dog back and forth between our apartments?"

He suddenly gets nervous. She has that look on her face, like she might hit him or pinch his ear off if he says the wrong thing. He is suddenly unsure of how to phrase his suggestion.

"Well… we could… ah….. haveadoggysleepoverPLEASEDON'TSHOOTME" he finished in a rush, covering his ears as he half-turned away from her.

"Okay." She shrugged and turned away, as if it were no big deal that she just agreed to have a "doggy sleepover" with Castle. She started to walk away, happy with herself for the casual way she agreed, though her heart was racing.

She took a few steps away, waited until she figured he was almost done picking his jaw up off the floor, and turned back only to find him standing right behind her. He leaned slightly down towards her, definitely invading her personal space, and said softly, "Your place, or mine?" Then he pulled back to look in her eyes, winked, and turned away.

She stood there, breathless, trying to form a coherent thought. It only took her a few seconds to regain her composure and come back with, "Castle, some of us don't have guest rooms the size of this precinct, so I'm going to have to say yours." She spoke as she walked up to him.

He turned around as she got to him, with that same sly smile on his face and said, "I know you love that bed. Don't lie. Though, I do have another one just like it if you want to try it out." He raised hid eyebrows suggestively a few times, and she rolled her eyes and said, "In your dreams, Castle."

"—"

"No comment" She shot at him before he had time to respond.

"Fine." He said out loud, though he muttered, "If you only knew."

She heard him, however, and said, "If I only knew, Castle, I probably would shoot you."

"Ah, too true my fine Detective. Too true."

A/N: I know it's really short. Should I continue?
