Chapter 5

Dirty shots

"Come to my bedroom, I wanna show you something."

These were Castle's words after he finished reading the scene from "Heat Wave" to her.

"Haven't I heard that before?" Kate joked but didn't protest, just got up and followed him to the bedroom. She didn't even need to think about it twice, she quickly decided to follow Castle and see what he was up to.

He made her sit on the one side of the bed. "Look at that," he stated, pointing at the cupboard near the bed.

"What am I supposed to be looking at?" she asked, confused.

"The bottle of tequila," he clarified, taking it off from the cupboard, putting the bottle on the nightstand right next to her. "Wouldn't be a waste not to drink it?" he stated. "Wanna drink some shots?" he suggested nonchalantly and looked at her.

She thought about it for a moment. She couldn't help but ask herself was this some kind of a trick. Was Castle planning to do something like the previous time again? Maybe he wanted to seduce her once again and leave her hanging. But wait, that was her plan, too. So she couldn't let him win. He had distracted her from her mission with his whole reading to her the book but now she was focused once again. Or at least tried to stay focus and not let him play any other tricks on her. This time she wanted to be the one who played him. Kate wanted to play her own game. She was planning on getting Castle hot and bothered and leaving him just like he did. That was going to be her revenge. Though she may forgotten about it for a brief moment, or maybe not so brief - whatever, she was going to do it. She was determined to get back at him. So when Castle asked her do drink shots she really had to think about it. Think about his intensions and make a plan.

Kate couldn't help but think of the scene from "Heat Wave" that Castle read to her just a while ago and the fact that it all started with tequila shots. That was how Nikki and Rook started their affair - by drinking shots, and eventually they ended up in bed. So she quickly made a plan in her head and smiled mischievously at herself. "Sure," she answered nonchalantly and shrugged. She didn't want to seem too eager about it. She wanted to sound like "Yeah, whatever. I don't mind drinking shots. I wouldn't mind if we don't drink, too."

"I'll bring glasses," Castle said and quickly went out of the room, then came back after a few seconds, carrying a tray filled with small glasses, a lemon and salt. He put the tray on the nightstand tight next to her and filled each glass with the liquid. He cut a few small slices of lemon and carefully put them on the tip of each glass.

Then he sat right next to her on the bed, giving her the first glass of shot. The book and more specifically scene with the shots Rook and Nikki were drinking could get out of her head. She could see the picture in her mind and it wasn't going away any time soon so she really wanted to try it out for real. With Castle. That was the plan. But she didn't know how to ask him to lick the salt off each other's hands, or bodies, or... She had to focus! Kate decided to keep silence at least for now. She wasn't going to ask him right away. She got too scared to ask him straightforwardly anyway. Seeing that he took the salt, licking his hand, she did the same. After he sprinkled some salt on his hand he passed it on to her and she couldn't help but notice the way his fingers brushed hers lightly. She shivered just from this small contact, knowing what he could do to her with his hand. Picturing what he could do to her in her mind. Damn that bastard and his stupid hand! And his fingers, too! Images of the scene that he wrote for her and particularly one detailed description came to her mind. And she just couldn't get it out no matter how hard she tried. But she really needed to stay focus. So Kate just tried to put that thought away, and did the same as Castle, licking the salt off her own hand.

"Cheers," Castle said, clicking the glass with hers and quickly drank up the shot. And so did she, sucking the lemon after that. The first drink came down easily.

"Another one?" he suggested, pointing at the glasses set on the nightstand. There were so much more to drink.

"Okay," she nodded.

Since the salt was still in her hand she licked her wrist this time and then sprinkled some salt on it and then gave it to Castle.

"Wanna make it more interesting?" he asked with certain enthusiasm, taking the salt from her hand. "Let's lick the salt off each other," he suggested.

Maybe it was kind of obvious that she really wanted it because Castle didn't even wait for a response, and so she didn't say anything. All he did was to silently ask her for permission with his eyes and she gave him her hand in a response. He caught her hand in his, moving it to his mouth and slowly licked the salt she had put on her wrist. Seeing the way he licked her wrist so slowly and deliberately, she was glad that he was holding her hand tight because it started shaking. Damn Castle and his tongue! And all the things that he could do with it. She could picture it pretty vividly. But he finally let go of her hand and drank up another shot.

It was her turn. But she was too scared to ask for some other place, a more intimate one. And plus, it was too early. She was going to torture him slowly. So she went for his hand just like he did. She licked his wrist off and sprinkled some salt on the wet place, licking it slowly. Her tongue lingered there, licking the same spot over and over again. Then she took the shot and drank up. She was afraid even to look at him at that moment because if she looked at him he could probably read her. Read all the dirty things that were running through her mind lust by seeing the lust in her eyes.

"Since we get to choose the spot, I choose..." he made a small pause, getting near her ear "your neck," he whispered.

Her neck. It wasn't that bad, she thought to herself. Was it getting hotter in there? Because she definitely felt warm and even hot but she blamed the tequila shots for that.

"Hold my drink," he said, giving her the glass. Then Castle moved closer to her neck and she shivered when he brushed her ear while moving her hair out of his way. He quickly licked the spot right under her earlobe and she caught the glass more tightly in her hand, careful not to spill it. She tilted her head to give him more access as he sprinkled the salt on her neck. But as he started licking the spot under her ear so slowly and deliberately, she quickly bit her lip, trying to hold still. No matter how hard she tried, she couldn't help but moan his name when he licked her sensitive earlobe with the tip of his tongue.

"Castle... " she moaned his name softly and involuntary as he ran his tongue around her earlobe so slowly and deliberately. "You're not playing fair," she mumbled, trying to smooth things out. But he didn't say a thing, he just took his drink from her shaky hands and that wasn't very fair, too. And plus, she could even see the smirk on his face while he was drinking his shot. That bastard! He really wasn't playing fair. So she wasn't going to play fair, too. Tit for tat. She was going to give him a taste of his own medicine. She quickly took the salt in her hands and gave him her glass, and moved nearer him, close to his face. Then she licked the spot under his ear, making it wet for the salt.

"Tilt you head, Castle," she purred his name seductively in his ear and when he obeyed she put some salt on the spot where she had licked him, and after that she started licking him there more slowly and purposely. Then she grazed his earlobe and tugged it lightly, making him arch his head back, suppressing a moan deep inside his throat. She saw the way he swallowed hard to suppress his moan and so she smiled at herself. She took the shot from his hand, drinking it up.

Then Castle took her hand in his and she rose up. "For the next place of your body you have to strip off your dress," he noted.

"What?" she asked, confused as she looked at his blue eyes.

"It's your belly," he stated confidently.

Her belly? That wasn't so bad. She could live with that. Her belly wasn't that sensitive spot, or at least she hoped so. It was close to her hot spot but she tried not to think about it because it wasn't helping at all. She tried to look very calm as Castle started unzipping her dress. She had nothing against him stripping her dress but she didn't like the way Castle was doing it. Or it was quite the opposite because she liked it very much. Way too much. He was brushing her naked spine with his fingertips and slowly unzipping the dress. He just wasn't playing fair. And plus, he was so very close to her. So close that she could feel his hot breath on her shoulder as he was unzipping her dress. And it seemed like it was taking him hours to unzip just one simple dress. Bit he was doing it on purpose, she could tell. That bastard knew how to tease her without actually kissing her or touching her on an inappropriate place. And he was very good at it.

Then finally she sat on the bed again as he pushed her down, going on top of her. First he removed the lemon and took the glass with his hand. Then he bent down and put the glass on her belly and she shivered when the cold glass made a contact with her warm skin.

"Stand still or you'll spill it," he instructed her and started licking her belly, getting it wet with his warm tongue. He sprinkled some salt there and started licking it again. He was looking at her and she was staring back, seeing him still licking her belly even when the salt was long gone. Then his tongue started moving all around her belly, licking slowly and tentatively around her navel. She shut her eyes, throwing her head back as the tip of his tongue touched her belly button. She bit her lip hard when he swirled his tongue there and then around her navel, suppressing a moan, desperately trying to stand still. Damn Castle and his orders to stay still. How could she stay still when he did that to her? He finally took the glass in his mouth and drank the shot up.

Kate looked at him, wondering where to lick him next in order to get back at him. She was in her underwear and he was still fully clothed and that just wasn't fair. "Take off your shirt," she said and he silently obeyed her. "Lay on your stomach," she instructed him.

"Why?" He asked, obeying her without any hesitation.

"I am gonna lick it off your spine," she explained to him. She moved around and bent down, getting closer to Castle. And then she started licking his spine, sipping salt there after that. Castle seemed pretty solid and didn't even move. That wasn't very fair. How could be so focused? She drank her shot, thinking about next place that she was going to choose.

"Lay on your belly," Castle instructed her gently and she looked at him questionably. "It's the small of your back," he clarified for her the place where he would lick her next.

She silently obeyed him, not knowing what exactly he was planning to do to her. The small of her back. She walked right into that one. It was a very sensual place and he probably knew that very well. How did he know that her spine was so very sensitive, she wondered. Well, she could easily say that she every spot of her body was sensitive if Castle was the one who was licking and touching it. Or kissing it. Or both. She really needed to stop thinking about it and yet she couldn't. First it was her belly and then it was her spine. Where would he lick her next? Between her thighs? He would lick her there without any mercy until she started begging him? To stop? Or to continue? She put that thought away, trying to concentrate on the thought how to make him beg and not be the other way around.

After she was on her belly, Castle hovered above her while Kate was waiting patiently for him to begin. He licked the small of her back gently and very quickly, making her want more. She was starting to get impatient. And yet she couldn't complain about it. She didn't want to say anything to Castle. She wasn't going to let him win. So she just bit her lip, silently enjoying the small and quick licks from Castle's merciless tongue. It was a bittersweet torture. But pretty soon it came to an end. Though Kate really wished it didn't. But her mind alerted her that she had to focus. She had to play it cool and not let Castle see how much she liked it. So she just rose from the bed, trying to look nonchalant.

She waited for a seconds, thinking which place on Castle's body was most sensitive. And how to drive him crazy. How to make him give up. To make him beg for more. And soon enough the thought of something. The next spot would be his neck. This time she hoped that she would be able to hit just the right spot. She was going to play rougher since he had deserved it. She didn't warn him though, didn't say a word - she just got closer to him, looking in his eyes which were already filled with lust and yet he obviously wasn't ready to admit it. But she was going to make him confess. Or otherwise, if he didn't give up, she would make him suffer. She would torture him more. She was ready for it. Kate was well prepared and hoped she would win this game. She licked his neck at first just for a brief moment and after she sprinkled the salt she continued with her mission. She was licking around his pulse point, getting a bit rougher with it, sucking his sensitive skin there. By the time she was done, his neck got a bit flushed where she had sucked him and licked mercilessly. So she drank her shot, seeing that Castle wasn't going to give up. At least not yet. So Kate wondered what he had in mind next. Where would the place the salt?

"Get on your belly," he instructed her as he just had read her mind and she did it without any questions. "I am gonna lick the salt off your butt," he added when she was already laying comfortable on her stomach.

"My butt?" she turned to face him, searching for his face to see if he was talking seriously. "Castle you're not putting anything on my butt," she protested.

"Relax, it's gonna be on your butt cheek, of course." he reassured her. "Don't you trust me?"

Didn't she trust him? She most definitely did but Kate didn't know if she could trust herself. But she didn't say anything - she silently agreed by burying her face in the pillow. Castle tucked her panties away slightly, baring her skin just enough to make a place for the salt. When he licked her left butt cheek she curled her toes, trying to hold still. She felt how he sprinkled some salt on her naked skin where she had licked her earlier. And then he started licking it off. He used slow deliberate licks, swirling his tongue round and round her sensitive naked skin over and over again. She grabbed the bed sheet underneath her and squeezed it lightly. But when he moved his tongue slightly to the right direction, she squeezed the sheet more tightly in her hands, burying her face deeper into the pillow, trying not to make any sound, or moan or even scream. Because what he was doing to her was pure torture. But she just grunted in the pillow, trying really hard not to move or squirm or maybe push her hips further into his merciless tongue. Because Castle just had no mercy. She was really close to give into the sweet sensation. Actually she was just about to move her hips into his mouth and moan freely without any restrains when she felt that Castle was moving back her panties on. Then he moved away from her, getting off the bed. That bastard! She didn't even see if he drank his shot or not. Not that it matter anyway. The shots had become just a pretext a really long time ago. They both knew that. Kate was well aware of Castle's intensions or at least she could take a guess. She knew he was trying to seduce her. But what she didn't know was whether Castle wanted to torture her just like she wanted to do. To torture him bit by bit. Or was he planning to stop like the previous time? She didn't care much anyway because she was planning to win this. So his intensions didn't really matter to her. The important thing was the game. And she needed to focus and think of a way to win this game. Because this time she had to make him go wild. She had to make him beg for more. He went too far and she was going to return the favor.

She quickly decided this time would be his chest. A very sensitive spot, she hoped. She didn't let him know though, she just told him to lie on the bed and he did what she asked. When she got on bed and straddled him in order to lick his chest she immediately felt his erection under her hips. But she needed to focus and not do anything too blunt. She bent down to lick his chest, looking at him. His chest fell up and down as he breathed harshly when she moved even closer. The way he was looking at her - with eyes filled of lust - she felt so giddy and desperately wanted to do so much more than just lick his chest. But she had to repress herself, wanting just to torture him. So she sprinkled some salt on his chest and stared licking it. She went way beyond the perimeters of the salt, licking further around but he didn't say anything. She felt just how much he enjoyed it and yet he didn't make a sound. She swirled her tongue around his nipple, licking it as she moved her hips, rubbing her own body against his. She wanted just to tease him. But honestly, Kate didn't know who she tortured more - Castle or herself. Because it was definitely hard for her to resist him. And obviously it was hard for him, too. Both metaphorically and literally speaking. She didn't know about Castle but she was dying to move her lips and just kiss him, and taste him. And do things to him... Feeling his damp chest against her naked skin felt so erotic and pleasurable. But the bastard didn't say anything. He was so calm and well-possessed. Well, he was moving his hips rhythmically just like she did in order to torture him some more but other than that - nothing. She had no idea before but it seemed like he had the patience of a saint. Bastard! It was obvious that he liked it. Ohh, he enjoyed it so very much but he was playing it cool. In fact, he probably was enjoying it even more than her but the nerve he had - to hide it so well! She was glad that he was still wearing his pants on because she was getting wetter and wetter with each move they made. She was so close to change her mind and give up on the game just because. But she had to make him suffer some more. It wasn't enough for her. And plus, he didn't react as she expected. So she finally gave up. She got up and drank her shot.

The hard part was coming. It was Castle's turn. She just hoped she wouldn't be coming, too. Kate knew pretty well that after what she did to him Castle would do much, much worse. Or much better - depends the way you look at it. But she wanted to be able to resist him. He had to be the one begging. She just had to make him suffer just like he did. He played her before so now it was her turn. She wasn't going to give up yet. Not until he gave up first. At least that was the plan. Until she heard him saying:

"I am gonna lick your inner thigh."

The way he said the words - with such a determined and sexy demeanor. He always sounded so confident and acted so smug. So he was gonna lick her thigh. Oh, boy she was so screwed! She didn't want to give up just yet though. So she just had to play it cool. Just like Castle did a few minutes ago. It can't be so hard, she thought to herself. And yet she wasn't even sure whether she would be disappointed if Castle tried to do something more than just lick the salt off her thigh or if he didn't even try anything at all. Because that was Castle after all. She didn't know which option she should be pulling for.

"Spread your legs for me," Castle instructed her with a low husky voice after she made herself comfortable on the bed. His words sounded so sexy to her that her belly trembled even before he had done anything to her. Just the thought of it made her sweat. She looked at him and silently obeyed his request by spreading her legs, granting him access to her inner thigh. He bent down and looked at her as she was silently waiting in anticipation. He started licking her inner thigh gently in order to apply some salt after that. Then he sprinkled salt and started licking her there. She knew he could clearly see how turned on she was because her panties were dripping wet. And he could probably smell her arousal from that close distance. And yet he didn't touch her or moved his mouth even an inch than necessary. He didn't try anything. That stupid bastard! He was going to drive her insane. Because she was definitely going wild. It was driving her crazy. His lick, the feeling of his wet swirling tongue against her hot sensitive flesh so close to her center... It was driving her nuts and so she was biting her lip as hard as she could to restrain herself from moaning. Or even screaming because he had no mercy with that playful tongue of his. She couldn't help but think of all the things he could do to her with his merciless tongue. And she could imagine them all pretty vividly at that very moment. How she could not think about it when he was an inch away from her center? Just one tiny small inch away from the place she wanted him most.

"Oh, Castle," she couldn't help but moan in the end. She just couldn't help it. And she didn't want to. Not anymore.

"What?" he asked, looking at her so smugly. He looked at her like he won. He thought that she was going to give up. And she was almost ready to do it. She knew she couldn't fight it much longer. But then she quickly changed her mind, seeing his smug demeanor. She was filled with want and yet she didn't want to give up just yet. She was going to win this. He would be the one to beg her. Now it was a matter of honor and pride. She just couldn't let him win. She didn't want to see him gloat.

So she responded, "My turn," as she rose from the bed. "Take off your pants," she commanded and he silently obeyed, quickly taking them off. She just bent down, getting closer to him and knelt on the bed, facing his legs. Then she just started at him, making him wait. He was wearing white briefs and she immediately noticed how see-through they were. But she needed to focus. She sprinkled some salt right under his belly and slowly started licking it off. She continued her path downward, her tongue going to the waistband of his underwear. She saw him twitching for attention and she haven't even touched him. At least not yet. But it was really hard for Kate to restrain herself. Even more when Castle just couldn't stop teasing her even for a few seconds. And it was really distracting when he did such things to her. He had his hand on her behind, touching her gently there, exploring, but she didn't mind it at all. Just a few seconds ago he had his tongue there so how could she mind it and why. In fact, she even liked it. She liked it a lot. But the mission was to tease him and torture him, not the other way around. She tried to ignore his naughty hand even though that every move he made was making it harder to concentrate because he was getting more and more inappropriate with each passed second. But she was returning the favor as well. She was still licking him, teasing him, circling round and round his navel with her tongue.

"I think the salt is gone," he stated calmly and lifted up his head to look at her.

It took her a few second to hear his words properly and to get the meaning of it. But she finally got what he meant to say - it was his turn again. He passed her the shot and she drank up slowly, hoping she could cool down a bit. She drank really, really slowly, buying herself enough time to prepare. To cool off a bit and just get ready for the next round.

"Take off your bra," Castle said after he took away her glass and put it on the nightstand. Kate took it off slowly and hesitantly, reveling her naked swollen nipples. They were so hard from all the tease and no real action. Hard just like his hard erection. He leaned on his elbow and got near her breasts. Then he sprinkled some salt between her chest and murmured, "Let's put this away," putting the salt on the nightstand when his hand brushed her nipple. Her body jerked, responding to his touch involuntary. "I am sorry," he apologized but she knew it wasn't sincere. Not even the slightest.

"Right," she answered skeptically, rolling her eyes at him, biting her lower lip hard in order to swallow a moan that desperately wanted to escape her lips.

"Yeah, I am not. Actually I liked it," he informed her and started licking the salt off her chest. "I am not the only one who liked it though," he stated smugly, interrupting his sweet licks, looking at her eyes but she quickly looked away. "You liked it, Kate, didn't you?" He asked, looking at her reaction as he encircled her nipple with his thumb. And once again her body responded but she bit her lip again to suppress a moan. "Say it, Kate. Say that you like it," he demanded, playing with her tight nipple. This time she couldn't help but moan, her body jerking with pleasure from his sweet assault. "Say it or I'll stop," he even threatened her. "Do you like it or not? Hmm, Kate?" he asked, purring her name in the end and turned his attention to her other nipple, teasing it as well. But she could see clearly that he was still waiting for an answer. And he could stop at any moment.

"Yes, yes," she gave away, gasping the words out loud. She just couldn't stand anymore. She just wanted more, not just a few teases and be over with it. She wanted him to continue and she knew that if she didn't say anything now then he would probably just stop. To show her he can do whatever he wants. To teach her. She didn't want to think about the game anymore. She didn't want to think about anything else but Castle at that moment. Everything else didn't matter to her. All she knew that it felt so good being under Castle. She enjoyed feeling his almost-naked body against her own, feeling his hot breath against her skin. She liked his sweet assault he was doing with his mouth and she wanted more. Immediately. She didn't want him to stop.

"Yes what?" he asked, giving her a satisfied grin. Then he continued with the sweet torture he was doing to her oversensitive nipple.

"Yes, yes! I like it! I like it, Castle!" she gave up, gasping the words breathlessly. She certainly didn't want him to give up on pleasing her so she had to confess. She didn't want him to stop. Not now. Not anymore. Not ever.

"Hmm," Castle just made a satisfied sound and looked at her. Her eyes were already pleading him to do something and she was just waiting. Not very patiently though.

And so he did. Kate moaned loudly the minute Castle's soft tongue touched her sensitive nipple. Now she could moan freely. She liked the way he swirled his tongue, licking her oh-so-sensitive skin. She could finally enjoy it freely without any restrains. She already gave up on the game so she had nothing to lose. And that was that. Just a few rushed licks and swirls of his tongue. But she needed more. She desperately wanted Castle to do something about it. But he just continued teasing her bit by bit. Each nipple at a time. Licking it, teasing her painfully slowly.

"Oh, Castle, please," she was going to beg him not to stop and just hurry up but at that very moment he sucked her nipple hard and she gasped out "fuck".

"Please, fuck?" he mused her. "It's what I intend to do," he stated smugly.

"Just hurry. Please."

He quickly obeyed and started kissing her chest, going down her stomach, placing a few angel kisses all over her belly. And she really liked where he was heading. But then he suddenly stopped and looked at her.

"Are you sure, Kate? Are you sure you want this?" he asked, looking at her.

"Ohh yess, Castle. I am not drunk or anything, I assure you."

"Oh, I know you're not drunk," he stated confidently.

"How do you know that?"

"Because this wasn't alcohol," he explained, pointing at the glasses on the nightstand and more specifically at the bottle.

"What do you mean?" she looked at him, puzzled.

"The bottle of tequila was filled with water. It was pure water, Kate." Castle informed her, smiling smugly.

"Oh, it was anything but pure, Castle." She answered back, smiling at him.

It was water. So the plan was his after all. Castle knew everything all along. He had planned this before she even came at his house. And in the end she was the one who ended up begging for more. But did that mean that he have won? And that she have lost the game? In her opinion it was pretty arguable. Well, since Castle continued working his way through, and she was feeling his wet tongue all over her body, exploring every inch of it slowly, she could most certainly claim that she felt like a winner.
