Rick Castle couldn't stop thinking about Kate Beckett. He had spent all day long with her solving the new case. During that day she was teasing him like she never have before. He was wondering what had gotten to her to treat him that way. She had said that she was dying to watch him squirm but was that really true? She totally had caught him off guards and he was wondering would she indeed enjoy that or did she just say it to tease him? She started to reveal a new side that he never knew existed in her. Rick had never thought that she could be such a tease for him. He never saw her as a dominant who would love to tease and torture him just for fun until now.

Castle liked Beckett very much. He liked everything about her: her short golden brown hair, her deep hazel eyes, her soft and perfect skin, her pink lips. He liked her tall, thin and oh-so-sexy body , in fact he loved every inch of it. He liked the way she dressed - a bit professional but still very sexy. He liked her smile - she usually smiled at him so brightly showing her perfect white teeth. And he also liked very much the way she bit her bottom lip when she was teasing him. He wished that this day would never end because he was dying to spend more time with her. Fortunately for him, it turned out that they had to spent the night together in a hotel. And they were forced to share one room since there wasn't any other vacancy. Castle was more than thrilled about spending the whole night in one room with Beckett. And Kate - she didn't seem to mind. He thought that it was like a dream coming true for him and he was really excited about getting to spend the night with Kate. But he was wondering about her opinion because she haven't said a word about it.

They both entered the room and looked around. The room wasn't very big - just a bed with a nightstand next to it on the left, and one big mirror and a drawer on the right side of the room. After looking around, they looked at each other.

"That's it? That's the whole room?", Kate exclaimed looking very surprised.

"So?'', Rick asked and looked at her in astonishment. He didn't see any problem with the room.

"There is just one bed!", she exclaimed, frustrated. "And it's so... so...", she started but trailed off.

''What?", he asked and looked at her eyes, raising his eyebrow questionably.

"It's just too small!", she exclaimed loudly, complaining about the bed.

"That's what she said", he mocked her with a boyish smile on his face.

"When she saw it", she continued his words and looked down at him, giving him a hint of what she meant by "it". Then she smiled lightly biting her bottom lip and looked at him provocatively, raising her eyebrow expectantly. Obviously she was enjoying herself teasing him like that.

''That was not funny!'', he exclaimed a bit offended. "I am deeply hurt", he said, making the most pained grimace he could act.

"Castle, seriously! How are we supposed to sleep in such a small bed?", she asked exasperated. This time she was looking pretty serious.

"Don't worry, I can sleep on top of you", he suggested with a bright smile, winking at her. He was trying to make her smile with his banter, to light up the mood.

"Castle!", she warned, giving him a stern look. Obviously she didn't find it very funny.

"Okay, okay", he gave up. "You can be on top", he said.

There was a trace of a smile on her lips but she quickly looked away. "You can't be serious even for a few seconds", she muttered to herself, playing offended by his words.

"Oh, I get why you are so upset!", he exclaimed as she turned around to faced him again. "You are worried that you won't be able to control yourself when we are all alone... in one bed", he teased with a smug smile on his face. "You are afraid that all your basic instincts will get the better of you and you won't be able to resist them", he said in a matter-of-factly tone.

"Actually, I can control my basic instincts pretty well, Castle. You see, right now all my instincts are telling me to punch you in the face but I don't." She said to him and then she walked away without saying any other word.

When he saw that she went near the bed and started to put her gun, her badge and all of her stuff in the drawer, he thought that they were going to bed so he decided to get ready. He quickly took his shoes, his pants and his shirt off and then flung himself on the bed while Beckett was still ordering her things in the drawer. Kate put her handcuffs on the nightstand and then took her coat off.

"Why did you leave the handcuffs on the nightstand?", he asked, dying of curiosity. It wasn't like anyone could get in the room or something and besides, she had put all her other things in the drawer.

"Precaution", she simply answered him.

"From what?", he turned and looked at her with a surprised face.

"From you", she answered, looking back at him. "If you even dare to touch me, I'll cuff you", she warned. She said it in a tone, sounding like she meant it seriously but the mischievous smile on her face told him otherwise.

"Was that a warning or an invitation?", he teased with a smug smile on his lips.

"You'll never know", she answered playfully. She didn't deny it and yet she didn't confirm it either. She was always such a tease for him. He could tell that she just loved playing with him and teasing him like that. After a few moment of silence, Beckett asked him:

"Can I borrow your shirt?'' She came near his side of the bed.

"Okay", he answered her uncertainly as she took his shirt in her hands. "Why?", he asked and looked at her expectantly but she walked away.

"Okay, thanks. Now close your eyes", said Beckett, standing in front of the bed.

"Is this the part where you come and kiss me to thank me?", he asked in enthusiastic tone.

''No. This is the part where you close your eyes so I can change", she answered him.

''Oh'', he sighed with disappointment and closed his eyes and then he even covered them with his hand. When she started taking her pants off, he peeked through his fingers and saw that she was standing with her back toward him. He thought that since she wasn't facing him she wouldn't see that he was peeking. So he moved his hand and started staring at her - she was slowly taking her shirt off. From his position Rick could see her whole back and he was also able to see her reflection on the front in the mirror. She was taking her time undressing herself real slow - one button at a time.

"You do realize that I can see your reflection in the mirror, right?", she warned him without even turning around to face him.

"What?", he asked startled and immediately covered his eyes. "What did you just say?", he asked loudly like not only couldn't he see her but also couldn't hear her. He was playing dumb and was going to deny her accusations.

"I saw that you were watching me", he heard her voice, which was coming somewhere near him so he opened his eyes. He saw that she was already dressed. He couldn't help but notice the way she was looking with his shirt on - the first few buttons were popped, revealing some flesh and the shirt was long enough to cover her tights but short enough to reveal her long beautiful legs.

"No, I wasn't", he denied, trying to stop staring at her. "It's just your imagination going wild", he suggested and looked away, which took him a bit effort of his will because she was breathtaking.

"Don't deny it. I saw it with my own eyes", she said, sounding pretty sure of what she was saying. He realized that he was totally busted and there was no way out. "I saw your reflection in the mirror. I saw the way you were staring at me so don't play innocent", she said to him in accusing tone. "If staring was a crime you'd be guilty as charged", she said to support her words.

"Okay, I confess and plead guilty!", he exclaimed enthusiastically. "You can cuff me now", he said and raised his hands above his head like he was surrendering himself. "You know I do like bondage", he reminded her as he winked at her playfully. She quickly lied in bed next to him and punched him in the ribs.

"Ouch! What.." he started but she interrupted him. He was going to ask her what was that for but she read his mind and answered his unsaid question:

"That was for staring at me", she told him while he was petting his ribs where she had hit him.

"See, I told you - you just can't control yourself around me", he said, looking at her. Obviously her instincts got the best of her - exactly like he told her.

"And next time it won't be just a punch, Castle. It will be far more worse", she warned him with a threatening tone, ignoring his last comment.

"You promise?", he asked teasingly. She didn't answer him so he took her silence as a positive answer. "So you promise that there will be a next time?", he continued to tease her as he looked at her brown eyes.

''No! What I meant was", she started to explain herself but trailed off, biting lightly her bottom lip. "Let's just sleep", she suggested and turned her back to him. But he didn't want to leave her sleep yet so he caressed her arm to get her attention and said in a teasing tone:

"By the way, I saw that you were watching me too".

"What? When?", she asked surprised as she turned to face him again.

''When I was taking my clothes off, of course'', he answered like it was the most obvious thing in the world.

"Oh, yeah", she said as she shook her head positively and bit her bottom lip. His jaw dropped from a surprise. He couldn't believe that she confirmed his suggestion. "In your dreams!", she said loudly in his face, mocking him.

"Actually, in my dreams I am the one who's watching and you are the one", he started but she put her hand on his mouth to silence him. But after she took away her hand he continued his sentence: "Who's stripping".

"Good night, Castle", she said and turned her back to him.

"Good night" Rick said to her and then turned on one side, facing her back and trying to fall asleep. He just lied there trying hard to doze off. But no matter how hard he tried, he just couldn't stop thinking about Beckett because she was too close to him and he could feel her lying next to him. He felt her body next to his, the heat of her body distracting him. He was so close that he could even smell her hair - it smelled like cherries. He tried to get as far as he could from her but the bed was too small. So he just tried to ignore her, to stop thinking about her. At that moment she turned around and they were face to face with each other. He suppressed all the thoughts that were rushing through his mind at that moment and closed his eyes, trying to concentrate on sleeping. But every time he opened his eyes and looked at her, she was looking at him as well. He impatiently turned around and lied on his back but at that time she turned around on her back too. No matter how hard he was trying he just couldn't forget about her. He even thought that the bed was getting smaller and smaller with every second. Not only could he feel her presence, but at that very moment he also felt her arm brushing against his. He liked the touch of her soft skin against his arm, the heat of her body. In fact, he liked it too much so he immediately turned around with his back toward her side and closed his eyes again. He was trying to imagine that he was alone in his bed but it was an impossible task. He felt that she turned around too and she was facing his back. No matter how hard he was trying, he still could feel her presence, especially when every time she breathed out he felt the heat of her hot breath on his neck. He turned around again, exasperated.

"Can't sleep?", she questioned him as she looked his face.

"Yeah", he answered, trying not to look at her.

"Because of the heat", she said quietly.

"What?", he asked surprised and looked at her. At first, he thought that he didn't hear her correctly.

"It's so hot in here", she stated. "You know, I usually sleep naked but now I thought it would be inappropriate."

Rick's mind went wild. After hearing Beckett's words he immediately started picturing her naked and this definitely didn't help him to cool off.

"Yeah, it's really hot", he confirmed because for him it was getting even hotter.

"Is this the reason why you can't sleep?", she questioned him raising her brow. He looked at her and thought about it for a second. He couldn't just tell her the truth. The heat wasn't the reason he couldn't fall asleep - she was. She and of course, his wild imagination. Even the thought of Beckett sleeping in one bed with him was arousing enough. But he couldn't just tell her that she was the one causing the heat he felt, that she lighted his fire. He definitely couldn't say that to her so he just lied and answered her:

"Yeah"

"You know, we can order some ice", she suggested. He considered her idea for a moment. He thought that ice cubes might help him to cool off. But then he couldn't help but picture a scene in his mind: Beckett ordering some ice, then taking one ice cube and slowly drawing it all over her body. He could imagine her soft and heated body, the droplets of the ice on her bare skin and he just couldn't stop picturing her all naked, shivering from the contact of the cold ice cube against her hot skin.

"No!", he declined a bit too loudly than he intended. He really didn't want ice because he knew he wouldn't handle the sight of Beckett playing with ice cubes. Not especially after Kate had told him she knew a trick with ice cubes which he wondered about ever since. She turned around again, so it seemed that she was going to sleep. He tried to suppress all the thoughts about Beckett and get some sleep too.

But Rick just couldn't doze off. His mind was racing with thoughts about Beckett. He just couldn't stop thinking about the fact that she was lying next to him. He stared wondering about so many silly things: "Is she thinking about what I am thinking right now? No, probably not... Did she fall asleep yet?" Kate turned around again, obviously still trying to fall asleep. "She is so close - just one reach away from me... Why she can't fall asleep? I wonder if she is going to snore during the night... What would happen if I just reach out to touch her? No, no! That would be very inappropriate!... I can feel her hand brushing against mine. Is she doing it on purpose? No, probably not... My shirt definitely looks better on her. Hey, I just realized that in the morning it will be filled with Kate's scent..." It looked like it was going to be a really long night for Castle.
