As promised, here's the first chapter of House Of Original Sin! In case you're wondering (which you probably aren't) about why I chose to change to a new series so suddenly, it was because I wanted Caroline's story to take a more mature route. One that I couldn't attempt in Obsessed. I'm not sure how far to take the Original's darkness and sadism, so I'm going to be asking my readers for their help and feedback. I don't want this story to be a fluffy epilogue, but I also don't want this to turn into an angsty fic. I'm making it M just in case I do decide to make it really dark.

Disclaimer: I do not own Vampire Diaries or Klaus (because if I did, he would NOT be in the body of Tyler).

Soundtrack: Pepper Spray by The Lisps.

"You'll really do this, love?" Klaus said quietly. He was looking at her like she was going to break if he pushed her any further. And Caroline realized that he was probably right.

I may not be saving the world… but at least I'm doing something right for once.

She took a breath, going on before she had a chance to regret it. "I willingly give myself to you, Klaus. But in return, you have to keep my friends and family safe."

"Of course. Anything for you."

"Then yes. You have my word, Niklaus Mikaelson."

Klaus then chose that exact moment to lean over and kiss her.

One month later…

And I never once regretted the decision that I made.

Well, maybe once or twice. But for the most part, I knew that I'd done the right thing. That I'd been the hero.

And living with Klaus wasn't so bad, really. He'd been decent, considering what an evil son-of-a-bitch he usually was.

As far as I knew, he hadn't touched Elena or the citizens of Mystic Falls. In fact, he seemed to have withdrawn from society completely. That probably got some people talking, but they could never guess the truth.

I'd left a note for mom before I'd gone. I'd told her not to come after me, because I was doing this for her. I even lied one last time: in the letter, I'd said that I loved Klaus. That he wouldn't do anything to hurt me. I imagined how much she must have worried after finding me gone, especially gone into the clutches of a killer. I wanted to assuage her fears that I was unhappy. I don't know whether she believed me or not, but I hadn't seen her in the month that followed.

That was mostly in part to the fact that I hadn't left the Michaelson mansion during that time. I think that Klaus was afraid that I would leave him, which was both cute and kind of pathetic. I mean, as if I could have escaped, even if I'd wanted to! We had a deal, and I had every intention of honoring it. Even if that meant sacrificing my freedom, I knew that it was worth it.

That night that I'd left my (normal?) life behind, Klaus had brought me back to the mansion in the dead of night.

It had gone like this…

All of the guests had gone home. It seemed cold and utterly endless. I realized that this would be my new home for a very long time.

My prison, actually.

I followed Klaus in a kind of numb daze. It was all happening too fast for me to process. One moment, I was feeling like Cinderella… and the next, I was Rupunzel (without the ridiculous hair, of course).

Klaus took my hand, and I was surprised at how gentle his grip was. The walk up the stairs felt like it lasted an eternity. And I grew more miserable with every step, like I was walking to my own execution.

I kinda am. Because when Stefan gets a hold of me, I'm so dead!

We stopped, and Klaus opened a door to what looked like paradise. A powdery pink paradise. My eyes widened at the dusty rose colored room, at least three times a large as my old one, with a kind-size bed underneath a soft canapy. Somebody (probably Klaus) had covered the duvet with rose petals. There was a vanity on the other wall, with a circular mirror above it. There was already a place to hang jewelry there, although it was empty. The drapes were pink as well. The floor was tiled, with a pink (obviously) ruffled area rug that covered most of them. Hell, there was even a crystal chandelier! Just when I thought that the room wasn't perfect enough, Klaus guided me to the closet, which was really the size of another room. It was heavenly.

I had to hand it to Klaus, he knew how to pamper a girl.

"You think you can buy my love with lots of closet space?" I said, only half-joking.

"You like it, then?"

"Like it-? I love it." I said honestly. Klaus was watching my reactions with such boyish enthusiasm, like everything weighed on my opinion.

"It's really all for me?"

"You deserve no less, my dear Caroline. If there is anything more that you desire, you need only ask-"

"No!" I interrupted in horror, "No, there's nothing else you could possibly give me!"

I couldn't believe that I was giving in so easily, after only an hour. I really was weak. But how could I be angry with the man who'd just put so much effort into making me feel comfortable?

I'll be pissed tomorrow. I told myself. But for now… I'm gonna enjoy it!

My pleasant mood was soon dashed.

"I see you brought the bimbo back with you." Said a voice. We retreated from the room to see that Rebekah Michaelson was leaned against the doorway of what I assumed was her own room, arms folded over her chest. She stared pointedly at Klaus's hand, which was still entwined with mine. Klaus seemed to step in front of me in defiance. I tried to take my hand back, but Klaus used his strength to keep it firmly where it was. I wanted to roll my eyes at his show of masculinity.

"It takes one to know one, Rebekah." I snapped back. It was my natural reaction towards vampire skanks, after all. Well, apparently a run in with the bitch was enough to remind me why I hated them all.

"Easy, sister. You wouldn't want to scare off the lady before she's even settled in." Kol said, coming up behind her. They were both still in their formal attire, though Kol was nursing a glass of amber liquid in his right hand.

"Let's go, brother. I'm afraid Nik's guest has left a bad taste in my mouth." Rebekah sneered.

"But then I'd have to pretend to pay for my alcohol!" Kol started to complain, but seeing the look his sister was giving him, he sighed in resignation. He disappeared into the room, and came back empty handed. Rebekah glared at Klaus and I as they left in a flash of vampire speed.

I let out a breath I hadn't realized that I'd been holding.

"I'm sorry about her… Rebekah just needs time to adjust to the idea…"

"The idea that I'll be living with her? Do you really think I'll be around long enough to change her mind about me?"

"Absolutely." Klaus said. "It may take a few thousand years, but I have no doubt that you'll come to understand each other."

A few thousand years? I groaned.

My face fell, and the weight of the situation finally fell on me. The life that I'd thought that I'd have was now out of my reach. It was ruined. I couldn't even see my best friends anymore, because they would try to "save" me.

"What's wrong?" Klaus asked.

"I'm tired." I said. I was truly on the verge of collapsing. I wondered if vampires could go into shock?

"Of course." He murmured, finally letting go of my hand. It was warm and tingly, but I told myself it was just because of a lack of circulation.

I expected him to leave me then, but he followed me back into the room. I sat on the bed, my eyelids suddenly feeling very heavy.

I tried to muster some moral outrage at the fact that Klaus's body was pressed against mine. I let out a contented sigh as he massaged my shoulders with slow motions. I could almost forget that I was being helped by a psychopathic hybrid.

"Would you like some help with this?"

I shivered- He was easing the straps of the blue dress off. I could feel his fingers ghosting over my skin. I was so tired, I couldn't even give him an answer. But he seemed to understand. The zipper came next.

"If I didn't know any better… I'd think you were trying to take advantage of me, Mr. Michaelson." I teased, but it came out more like a sleepy, seductive whisper than I'd planned.

"I'm always trying, love," Klaus said. Then he pressed his lips against my neck.

We both froze. Then I finally came back to my senses. There was fraternizing with the enemy, and then there was enjoying it… which I had to admit I was.

"Get. Out." I hissed, turning away from him. I knew that I had probably wounded him badly, but I was really angry. Whether it was at Klaus or myself, I didn't know…

Things hadn't changed much since then. Now, I was still bipolarly tolerating Klaus, while he tried to buy my affection. More often that not, it earned him a moment of tenderness, that I would then shove back in his face. But he was eternally patient. I wondered when he would finally crack, though. Rebekah avoided me like the plague, which I was more than happy about. Kol… well, he was still a creepy, suave douche-bag, as far as I could tell. I caught him watching me like a hungry animal, and I was a prime piece of meat. I was reminded that underneath that easy-going attitude, every Original, including Kol, was savage. But somehow, I knew that Klaus was protecting me.

I couldn't being myself to leave the mansion yet. Seeing my old life, seeing the lives of the people in Mystic Falls, going on as if this nightmare had never begun… I couldn't bear to witness that. And I doubted that Klaus would want me to either, for fear that I would double cross him. Not that I would ever tell him that I was no longer even considering that option.

One day he visited me in my room. I was sitting in bed reading a book. I admit, I'm a total sucker for mainstream literature (hey, there's a reason the stuff is so popular), so I'd requested The Hunger Games almost immediately when I realized that I would be stuck in the Michaelson mansion devoid of entertainment and company most of the time. Klaus had delivered it to me with a smirk, nagging me about my bad taste in books. I'd told him that I wasn't ancient enough to appreciate the classics like he was.

"Hello, Caroline."

"Klaus." I returned coolly.

He made no move to sit next to me. He wouldn't unless I invited him. That was an unspoken rule that we'd come up with over the weeks. Strangely enough, Klaus respected me in a way that was superior to any boyfriend that I'd had in the past. I didn't think that it would last, given how frustrating I was being, but it was nice anyway.

I inclined my head towards the empty space on the end of the bed, and he took the invitation. I continued reading for at least an hour, and his eyes never left my face. I could hardly focus on Katniss kicking ass in the arena. Sure, it was uncomfortable, but I wasn't going to cave and speak to him. Luckily, he spoke first.

"Are you truly content to waste away up here?"

"What else can I do, Klaus?"

"You could go outside. I could take you away from here, if you wanted. I'd still hoped that you were interested in seeing the world."

"I don't know what I want anymore." I said exasperatedly.

"You are unhappy, aren't you?" He said, more like a statement than a question.

"I miss my family. And my friends." I admitted after a few moments. Saying it out-loud was worse than brooding. I set the book down on my lap and sighed.

"Caroline… you know that I didn't say that you were forbidden from seeing them again."

I thought frantically back to our conversation three months ago. I'd just assumed… "But—I—"

"You misunderstand. I am not some heartless monster. I of all people know the value of family, the importance of your flesh and blood. I also know how painful it is to exist alone. I would never deny you your loved ones."

"Then I… I can go?" I asked hopefully.

"I will most likely escort you where you need to go… but yes."

Boy, did I feel stupid. The mansion had been a prison of my own making. And the truth was, I hadn't come to terms with my decision completely.

"Well then, let's go! I have a lot of shopping to make up for!" I said eagerly. "I need a distraction."

Of course, I would go visit my mother too. But I just wasn't ready to be confronted by Elena, Bonnie, the Salvatores, or even Matt. The thought of their judgment terrified me even more than a showdown with Rebekah. And I'd probably end up having to admit that I wasn't trying to escape or plotting against the Originals like they'd all expect me to.

Klaus put a steady hand on my arm, as if trying to calm me. "Your wish is my command. Also, Mother requested that we gather together for a formal family dinner for tomorrow night."

I raised an eyebrow. "That's good to know. I guess I'd better buy Catching Fire then, because I'm almost done with the first book."

I was ashamed at the disappointment I felt at the thought of not seeing Klaus for a night. His visits were the most consistent thing in my life at the time.

Klaus chuckled. "Caroline… you're going with me. You're a part of our family now."

I was speechless. A smile came to my face, and I couldn't force it to disappear. God, I was so pathetic, like some stray puppy looking for a home.

He stood. "I'll see you tomorrow morning. I'll take you to see your mother, and whatever else you'd like. Whatever makes you happy."

"Klaus?" I asked before he was out the door, "Were you serious about marrying me? Or was that just a front for our deal, so no one would get suspicious?"

He paused, staring at me so intensely that I felt like squirming. "I have never been so serious about anything in my life, Caroline. I want to declare to the whole world that you are mine, and will never be anyone else's."
