Chapter 21

Kate put the kids down to sleep, while Castle packed up all their toys and gifts into the corner of their room. They had got so many new clothes and stuff from everyone that he would have to install a new set of drawers in their room.

When he was done, he came over to find Kate sitting in the rocking chair trying to put Nate to sleep.

"How is it that Jo never gives us any trouble when it's time to sleep, but this guy's always awake?" Kate laughed and said "Shhh... he's almost fallen asleep now"

Rick, nodded and turned around. He went to Jo and kissed his sleeping baby girl goodnight. And that's when he heard it

"Da…da"
he stood up straight, and looked behind at Kate. And she was smiling back at him.
"Please tell me you heard that Castle!"

"Oh! My! God! That was Nate!?"
He strode to where they were.

"Da…da" he said again
and Castle reached down to take Nate from his mommy. He carried him and looked at him

"say that again. To me"

Kate's eyes sparkled as she watched the happiness on castle face.

Nate touched his Nose. Squeezed it and said "Da…da"

"You DO talk!"
"What'd I tell ya" Kate said. And Castle kissed his little son, spun him around a few times and made him give him a high five too.

"Wow, you just undid all the efforts I took to get him to try and sleep." Kate chuckled.

Nate was wide awake now. And Castle was blowing raspberry kisses into his tummy. His soft giggles filling the room

"I don't care. My son just said his first word and it was dada"

Kate knew how much this was massaging his ego. He was so flattered right now; she knew she won't hear the end of it for the next week or so.

"Kate, why don't you go get that piece of ice- cream cake I saved us, and wait for me in the bedroom. I'll put this guy to sleep and meet you there."
"So you really did save a piece ha?" She bit her lip, already picturing the parts of his body she wanted to lick the ice cream off of him in her mind...

"How could I forget? I've been waiting all day"

"Okay… I'll go get it. But if he's not going back to sleep, let me know... I'll come get him"

Kate left the room and walked out to the kitchen. She opened the refrigerator and took the cake out. She picked out the piece of strawberry from the cake and put it in her mouth. She closed her eyes and savoured the taste of the juicy fruit on her tongue.

She cleared up the kitchen and turned all the lights off, making sure all the locks on the front door were on, giving Castle enough time to put Nate to sleep.

He met her at their bedroom door.
"Did he give you any trouble?"

"Do they ever?" he asked.

And she chuckled. He leaned down and kissed her lips…
"Hmmmm" he hummed.
"Someone's started desert without me. You taste of strawberry."

"What's with you and fruits Castle? Your safe word is apples, you think my hair smells of cherries, and now I taste like strawberry?"

"You just don't want to admit you ate the last strawberry from the top of the cake." he looked at her through narrowed eyes.

She avoided eye contact and said
"well, looks like I need to be punished for it." he opened the door and led her through it.
"I have a sweet punishment in mind."

"And what's that."

"You'll just have to wait and watch.." he took the cake from her and slid the tip of his finger to pick up a good amount of ice cream on it, but just as he was about to taste it, she grabbed his wrist and took his finger into her mouth.

And that in itself was enough to turn him on

she licked the ice cream off his finger, closed her eyes and moaned at the taste of it on her tongue. His eyes darkened watching her. And the things her tongue was doing to his finger were making him swear out loud.

He knew all too well that she had a talented mouth and the sinful images she was creating for him, with that mouth, and those eyes and that wicked smile that only loved to tease him.

"Katherine Castle, if you don't take this plate of Cake from my hand right now, I might just drop it down and I don't think you want it to go to waste. She took it from his hand then and kept it on the bed behind her and immediately began to undress him.

An hour later, the plate lay empty on the bedside table, and the two lovers, panting and staring up at the ceiling with blissful smiles on their faces.

"You're my favourite dessert you know?" Kate told him between breaths.

"Do you want a second helping then?"

"Second?" she asked with a sultry smile as she turned to lean over him. She kissed him. And whispered,
"I think you post coital haze has made you lose count of how many helpings I've had.

"Probably" he admitted. He kissed her again then.

"We always have the best sex when we fight" he said between kisses.

She pushed him away.
"What?" she chuckled.

"Don't you think so?" he asked.

"Is that why you always fight with me?"

"hey, I don't start the fight, you do." He argued playfully

"You're doing it right now."

"No I'm not"

"Yes you are"

"Am not!"

"Shut up and kiss me!"

"Gladly" he said and covered her entirely with his body.

And in her mind, she had to agree, sex after an argument ALWAYS made it to their top 10 list.
