Chapter 1

It was early morning and Castle and Beckett were already up, drinking their coffees and getting ready for work.

"I have a surprise for you, Kate" Castle declared after they finished off their coffees and went out of the room to get the present, leaving her hanging.

"Really? What is it?" Kate asked after Castle showed up again, intrigued by the surprise, looking at the box as he was holding in his hands.

"It's a gift. For you," he said and smirked contently.

"But it's not my birthday, Castle" Kate said and wondered what could it be. And why Castle was giving it to her without any special occasion. She was really curious to find out.

"Just look at it, Kate. I bet you would like it," he said so confidently with such a smirk on his face and then he gave her the present. He was looking pretty smug about it and Kate couldn't help but wonder why. Why was he so excited about it? Was there any catch? Something was going on.

"What did you do, Castle?" Kate asked immediately, thinking about the only reason he could give her a present - he did something wrong. That was the only thing that crossed her mind.

"Open it," he insisted, shaking his head with excitement with such a bright smile. He was very excited, she could tell. And yet, she didn't know why. So she finally started unwrapping the present slowly and uncertainly, looking suspiciously at Castle from time to time. Then she saw the gift and took it out of the box.

"What's that?" she asked, looking at it with a puzzled look.

"Vibrating panties!" he announced enthusiastically, looking at her with such an excitement.

"Oh," she exclaimed. She really didn't know what to say. She was definitely surprised. He definitely took her off guards with that gift. And now she understood the reason why Castle was so eager for her to open it. "Thanks, Castle," she said and gave him a quick peck on the lips. "Maybe we can try them out tonight," Kate said, lowering her voice, talking sultry at him and then she winked playfully.

"I was thinking you could try them out right now," he suggested playfully.

"Not now, Castle. We will be late for work."

"Come on, Kate. Try them now," he whined like a petulant child. "Or just put them on and we can try them out later. You know, in our coffee break. But please, just put them on. Pretty please."

"Castle, are you five? I said I am not putting them on. And plus, I don't want to look suspicious at work. Nobody knows we are together, remember? We have to act chill and try not to draw any attention. We have to be very careful," she reminded him, justifying herself.

"Please? Pretty, pretty, pretty please," he begged. "I am not going anywhere until you put them on," he declared and crossed his arms, pouting at her.

"If I put them on, could we just go?"

"Okay. Of course."

"Okay, fine. Deal." Kate finally agreed though a bit half-heartedly. "But if I put them on you are not getting the remote." She declared and put the remote on the table, taking the panties out of the box.

"You drive a hard bargain, but okay. Deal. We will just leave it here. I don't mind... I can wait until we get home," he said and Kate just rolled her eyes and sighed exasperated. She didn't know why he insisted on putting the underwear on since he wouldn't have any control on the remote but she was way too tired and getting late for work to argue with him.

"And don't you think about touching the remote!" she warned him on her way out.

"Alright. I won't."

"Swear," she made him.

He put his hands behind his back and looked at her. "Okay. I promise you that I won't touch the remote," he said, crossing his index and middle fingers behind his back.

"Good," Kate answered. Then she left the room, going straight to the bathroom in order to put the panties on. And while she did so, Castle murmured to himself "I don't think so", taking the remote from the table, putting it in his pocket. Then they both left for work.
