SORRY! I know this has been a long time coming and I know it's really short but I feel self-conscious because this is dirtier than I have posted before and if this goes well, hopefully I can post more kinky shit, dirtier than this.

"C-Castle, truth or dare?" I asked still slightly shaky from his touch and imagining him doing much, much more.

"Uh dare Kate" he said sounding genuinely surprised. I looked over my shoulder at Espo to see him chuckling and shaking his head Lanie looked excited to see what I would say next.

"Well Rick, since I am so uncovered why don't you take off your shirt. And to make it interesting go get some toothpaste and put it on your nipples." I told him he looked confused.

"Why toothpaste?" he asked.

"Oh you'll see why." He shook his head I got off him and brought my knees up to my chest so Esposito wouldn't see anything I didn't want him to. Castle stood up took off his shirt and walked into the bathroom. I was surprised his chest was surprisingly well defined he even had a slight six pack, nothing like the powder puff we joked about him being. He came back with the tube of toothpaste and I copied his earlier words.

"Allow me" I said. I squirted some toothpaste onto my finger and lightly touched his nipple circling it and evening out the toothpaste then moved onto the next. I refused to look at his face if I did it would be too easy to lose myself in his beautiful eyes or find myself kissing those irresistible lips.

"Kate" he said my name so quietly I wasn't positively sure he'd said it. It came out of his mouth in a short breath of air and all of a sudden my nipples turned hard as rocks. I imagined him doing the same thing after he licked the sensitive flesh of my breasts or neck or stomach or…. I couldn't let my thoughts drift there. I had to keep this friendly, yeah right; there is no way we could stay in the friend zone after this. I watched as the toothpaste started to kick in, it started with a cooling feeling and then amounted to a cold burn.

"Fuck Kate" he growled my eyes widened a jolt of electricity shot through my body down to my core.

"Yes Castle?" I asked as innocently as I could given the current situation.

"How the fuck did you know toothpaste was so fucking arousing? Do you know how hard it is for me to control myself around you normally? You're to blame if I lose control Kate." His eyes looked darker and more commanding than I had ever seen them before; his posture was not relaxed like he normally sat. Rick was sitting with his legs shoulder width apart and his back was straight, even though I was taller than him because I was sitting on his lap he seemed to be leaning over me.

"Castle I don't have to answer, you didn't ask me truth or dare." He looked at me and his gaze seemed to get more forceful, I wanted to please him I felt like I was disobeying him and that killed me inside, a part of me that I didn't realize I possessed.

"Kate truth or dare?" I grinned at him.

"Dare me Rick." He gave me a look that made me want to cum in my panties, my final piece of clothing that I hoped I wouldn't lose tonight or at least not until Esposito and Lanie left. Wait a minute, what the hell am I thinking? It must be the alcohol except for the problem that I didn't have any, shit I'm screwed, metaphorically not literally I'm not being screwed by castle not that I don't want to...god Kate shut up! I came out of my babbling.

"Well Kate, I dare you to put some toothpaste on your clit." I looked at Rick wide-eyed. I had used toothpaste before, mostly on my nipples but only because it was so much more effective on my clit. I groaned in anticipation. Last time I did shit like this it started out with an innocent tube of toothpaste and then elevated to stuff that is much, much kinkier. Being with Castle made this all the more arousing and intense, things that made me smile with other guys makes me groan and writhe in pleasure I'm sure that an orgasm, if Castle had a part in it would be explosive.

"Damn Writer boy, you're finally stepping up and taking control of my girl, it's about time." I glared at Lanie.

"Fine Rick, can I do this one myself or would you like to help me?" I asked sarcastically. I grabbed the toothpaste and walked into the bathroom.

"Man, how have you not spontaneously combusted? You have been lusting after Kate for four years man, and now she's topless on your lap and you haven't looked down once! Are you sure you're not batting for the other team and secretly have the hot's for Ryan?" Esposito asked Castle, I could picture the curious and amused expression on his face and honestly I was curious to. I quickly applied a dab of toothpaste to my most intimate parts imagining castles hand doing the same.

"Man it's not like that, I just really care for Kate, and hell, since none of us will remember this tomorrow, I love her, I'm not going to stare at her nakedness unless she wants me to, I respect her too much to behave with such lustful actions and motives." I was shocked I wiped a tear from my cheek that I didn't realize had fallen.
