The Impala rumbled down the road as my mind went back to our case from four days ago. We had been hunting a siren that was posing as a striper. I hadn't enjoyed the case at all. The only way to kill the siren was with a bronze dagger dipped in the blood of someone under her spell. Unfortunately the blood samples from the victims had been stolen and we had no idea how we were gonna get what we needed. When we finally met back up with Dean he had been poisoned by the siren who was posing as an FBI agent. It had told Dean to attack Sam and he had and then the siren infected him too. I had tried to stop it from happening, but the siren grabbed me.

"Well, I don't know when it happened. Maybe when I was in hell. Maybe when I was staring right at you. But the Sam I knew, he's gone," Dean said. Sam got a pissed look and replied, "That so?" I wanted to stop the fight, but I wasn't sure how. "And it's not the demon blood or the psychic crap. It's the little stuff. The lies. The secrets. Even Cassidy knows something's up," Dean told him. I wanted the arguing to stop, but now I was in the middle of it. "Oh, yeah? What secrets?" Sam asked. I knew something was up with Sam, but I didn't think he was keeping secrets from me. "The phone calls to Ruby for one." Dean said and I was instantly pissed. Why was Sam talking to that no good slut? Better yet why wasn't he telling me? "So I need your say-so to make a phone call?" Sam asked.

I looked at him seething, not able to form words. "That's the point. You're hiding things from me and your girlfriend. What else aren't you telling us?" Dean asked and I really wanted to know. I was pissed at the siren for making them fight, but at least I had finally got some truth from Sam. "None of your business." Sam replied and it hurt me. We were supposed to tell each other everything, that's what couples do. "See what I mean? We used to be in this together. We used to have each other's backs. And look at Cassidy she's so upset she can't talk," Dean said. It was true I still hadn't found the words to tell Sam how hurt I was. "OK, fine. You know why I didn't tell you about Ruby, and how we're hunting down Lilith? Because you're too weak to go after her, Dean. You're holding me back. I'm a better hunter than you are. Stronger, smarter. I can take out demons you're too scared to go near. And I didn't tell Cassidy cause I knew she would want to help and I didn't want her hurt because of you," Sam said.

I found it hard to believe he found Dean weak this had to be the siren. And me hurt because of Dean? I couldn't see that happening "That's crap," Dean replied. I looked between them knowing they were about to come to blows. "Stop you guys. Sam you know Dean isn't weak and I wouldn't have got hurt because of him so please just stop. Even if I wanted to help that's my decision to make not yours," I said but I was ignored. "You're too busy sitting around feeling sorry for yourself. Whining about all the souls you tortured in hell. Boo hoo," Sam told Dean and my heart broke even more. This wasn't the Sam I knew and loved; he could never say something that cruel to his brother. But the siren had a firm hold on me and I couldn't get loose to stop it.

The boys began to trade blows until Dean grabbed an axe. I fought harder finally breaking free and swinging my fist at the siren. I tackled Dean to stop him from hitting Sam and saw Bobby standing behind him. Thank God for Bobby; he had the knife to kill the siren. He jabbed it in Dean's shoulder making him cry out, but that was the least of our worries. The siren had tried to make a run for it, but Bobby threw the knife lodging it in the siren's back killing it. We walked out to the Impala all of us grateful Bobby showed up when he did. We stood there awkwardly for a moment after Bobby left. "Dean, look, you know I didn't mean the things I said back there, right? That it was just the siren's spell talking?" Sam asked. Dean nodded his head and replied, "Of course, me too." I wanted to say something, but I wasn't sure what. "'Kay. So... so we're good?" Sam asked. I hoped they were because I didn't want tension between them. "Yeah, we're good. But you might want to talk to Cassidy," Dean told him before getting in the Impala.

Sam turned to me and I could feel the regret as well as see it in his eyes. "Look Cassidy I'm sorry. I shouldn't have kept the phone calls from you," Sam started. I pursed my lips and let out a deep breath. "No Sam you shouldn't have. I thought we were closer than that. Why didn't you tell me?" I replied. I could see the hurt in Sam's eyes at my words, but couldn't bring myself to care in that moment. "Because I know how much you hate Ruby and I didn't want you mad at me. But I realize not telling you was worse. Plus I really do want to protect you," Sam said. I looked up at him and let out a sigh. "I knew something was up Sam you should have just told me. Yeah I would have been mad, but I'm even more pissed you kept it from me. And I love that you want to protect me from Lilith, but I'm a grown woman and a hunter I can take care of myself." I said giving him a serious look. "You're right and I'm sorry. Are we gonna be okay?" Sam asked. I looked down and then back up at Sam. He was so hopeful things between us would be okay. "I forgive you Sam, but I think it'll be awhile before we're okay," I replied before getting in the Impala.

That was four days ago and we still weren't okay. I had taken to sleeping in the spare bed instead of with Sam. We hadn't held hands, kissed, or cuddled in days; I missed his touch. I barely slept at night and Sam was the same way. I had forgiven him, but I was still hurt about him keeping secrets from me. Dean wanted to say something to help us, but couldn't find the words. Emotions or as he called them 'chick flick moments' weren't his thing. However I could tell the tension was starting to get to him as well. I hated this void that Sam and I had found ourselves in and I wasn't sure how to fill it. I watched Sam as he slept in the front seat and let out a sigh. Dean looked at me in the mirror before back to the road. "Look he gets that he made a mistake, he apologized, you forgave him. Why can't you get passed this?" He asked. And I wondered the same thing. It really made no sense and I hated not feeling his arms around me at night, his lips when we had to part ways if only for a short time, his hand as it ran through my hair to calm me down.

"I don't know Dean. I really don't. Maybe it's because every time I asked what was going on he lied. Or maybe it's because I hate Ruby for convincing him to break his promise to you, for lying to him about saving you, for sleeping with him." I replied. Dean then gave me a small smirk. "I think it's that last one. Whether you want to admit it or not you're worried he's more attracted to her. And if he's having secret phone calls with her does that mean he'll leave you. Well let me tell you something Sam loves you. He may not have said it yet, but he does. He's not gonna leave you for that demon skank. She was a distraction you are the real deal. I promise you have nothing to worry about there." Dean told me. I was surprised he got so girly for a moment, but I appreciated it. "I appreciate the chick flick moment Dean. I needed it," I replied. "Yeah, well you tell anyone and I'll kill ya," he said causing me to laugh loud enough it woke Sam up.

We had just pulled into a hotel parking lot so Dean gave me a look that said fix this before getting out to go book our rooms. "Sam I'm sorry I've been so distant. For some reason I was worried you found Ruby more attractive than me and I thought you might leave," I said. Sam turned around and looked at me. "I could never find another woman as attractive as you. And I definitely don't want Ruby," Sam told me. I could feel how honest he was being and smiled. He reached back and grabbed my hand. "I promise I only want you and from now on no more secrets," Sam told me. I leaned forward and kissed him happy that things were better between us. We saw Dean walking toward us and got out of the Impala. He handed us a room key, grabbed his duffle from the trunk and went to his room. Sam grabbed mine and his bags before closing the trunk and we went to our room.

As soon as the door closed Sam dropped the bags and pushed me against the door his lips smashing against mine in a bruising kiss. I wrapped my arms wrapped around his neck while his went to my hips gripping me tight. We had gone days without touching in anyway and all those pent up emotions were pouring out. Sam ran his hand down my leg and pulled it up around his waist so he could grind into my sex. I moaned into his mouth loving the feeling. He broke our kiss and began kissing my neck before biting it eliciting another moan from me. Sam was in no way being his normal gentle self and I was perfectly fine with that. He pulled away from me for a moment before grabbing my shirt and ripping it off. My chest heaved as my heart began to race. I had never wanted Sam more than I did in that moment. Luckily my bra unhooked from the front so he didn't rip it as well; not that I would have complained. As soon as the cloth was out of the way he attacked my chest with kisses and bites that I knew would leave marks, but I couldn't bring myself to care. I leaned my head against the door and moaned again at how amazing his touch felt. He kissed and bit his way to the edge of my jeans. He undid them and then jerked them and my lacy thong down in one swift motion.

I had already kicked my boots off so I stepped out of my jeans. Sam removed all his clothes before standing back up and towering over me. The look in his eyes told me not to expect anything gentle. His lips claimed mine in a fiery kiss as he bit my bottom lip I gasped allowing him to slip his tongue in my mouth. He grabbed my legs and lifted them both and before I was truly ready slammed into me. His thrusts were hard and fast and I knew neither of us would last long. I pulled his hair and ran my nails down his back earning a moan from him. I sucked on his tongue as it went in and out of my mouth like his cock was going in and out of my hot sex. I began to buck my hips against his to form more friction. My orgasm began to build and I dug my nails into his back. In retaliation he squeezed my hips and bit my lip again. With a few more thrusts we began to cum together. Once our high began to wear off Sam carried me over to the bed and laid me down. "I promise after tonight, you'll realize you're the only woman I want," he told me. And I believed him with everything in me.

So I'm not a huge fan of the siren episode and I felt doing a little flashback was easier than trying to incorporate Cassidy into that case since Sam sleeps with that doctor chick. Hope you guys like this chapter. Please review and let me know what ya think.
