Hello, everyone!

So, just a quick warning: this will not be flashed out as an actual story with plot or anything of the sort. This will pretty much be a series of smutty one-shots that take place in this universe. It's unlikely that the smut will be "vanilla" and it might eventually turn into something BDSM-ish, but I'll make sure to warn you about what the smut will contain before each chapter. This one works mostly as an introduction to this universe, so all the NSFW stuff is pretty tame.

Also, those of you who follow me on tumblr (itsnotacrimetoloveyou) might be familiar with this, because I posted a version of this chapter as a drabble about a month or so ago. This chapter is pretty much the same as that drabble, but there's an extra scene. I also posted a part 2 of that drabble that I'm still not sure whether will be worked in on this story.

The title comes from Trouble by Halsey. And the beautiful cover was made by perse-phones (on tumblr).

I hope you enjoy this!

The dreams started the night she turned eighteen.

At first, she had chalked it up to his blood still being in her system, its power somehow messing with her brain. She was too scared and too embarrassed to take a closer look at them.

It is just a side effect, she'd thought, trying to convince herself of what, deep down, she knew to be a lie.

But how could she admit that she had nothing and no else to blame for those dreams? That every night she would wake with her thighs dampened with her arousal, her tank top sticking to her sweat-covered skin… It was all her own doing.

It didn't matter if it was unintentional, it didn't matter that she could not control her subconscious… It still felt like betrayal to wake up disappointed at the fact that Klaus Mikaelson was not by her side, was not touching her.

Caroline tried to avoid him as best as she could, but he seemed to be everywhere

His eyes would always meet hers, his lips would always be curved into an annoying smirk, and she would always blush for him, her heart beating so fast inside her chest she thought it might burst.

Sometimes he would only nod at her, staying a safe distance away... But some other times, he would take steps towards her. He would smile at her and the entire room would fade away, and all she could see was him, and all she could hear was her blood rushing in her ears and his voice.

Hello, Caroline.

It took no more than that for her nights to become even more frustrating, for her mind to imagine her walking into her room and finding him there, his eyes darkened as he looked at her.

Her dreams always felt so real. She could feel the shiver than would run down her spine, could feel the tickling in her skin as he undressed her with his eyes.

Hello, Caroline, he would say, just like in real life.

Then he would come closer to her, would cup her cheek with his calloused hands… And that small, chaste touch would be enough to make her blood boil.

He would press his lips to the corner of hers, then along her jaw and down her neck. She would pant softly for him as his teeth scratched her skin. When his hands started to wander, she would not stop him.

Klaus would slowly take off her clothes, stealing kisses and touches, and she would just close her eyes and ask for more.

His willingness to give her what she asked for varied. Sometimes he would torture her with slow and and barely-there touches, would lay her down on her bed and make her beg for what she wanted. His fingers would tease her folds or he'd taunt her with languid thrusts of his cock inside of her.

And then other times he would push her to her hands and knees, and fuck her so hard and fast she'd wake up with his name on her lips.

Each night she went to bed fearful and excited about what her mind would put her through.

The dream began with her going to his place for a change. To the mansion just on the outskirts of town, which she had broken in a few times with her friends when it was still unoccupied.

Caroline walked up the stairs, aware that he could hear her, that he knew she was coming to him. It made her smile to think of him lying on his bed, waiting impatiently for her.

She didn't bother knocking before opening his bedroom door.

He watched her like a hawk from the bed, analyzing her every movement, no matter how small. The way his lips curled, the sinful promise they carried, the way he said, "Come here, Caroline"… God, she couldn't help but respond to him.

Before she even knew what she was doing, she was placing her knees on each side of his body. Straddling him. His hands went immediately to her waist, squeezing it softly, while hers came to rest on his bare chest. Klaus leaned in to brush his nose against her neck. He breathed her in, she closed her eyes.

"Hi," she said softly when he pulled back to look at her, her hand reaching out to cup his stubbled cheek.

He didn't answer, choosing to simply capture her lips with his own… And well, she wasn't about to complain. His lips were so addictive. The way his tongue explored her mouth, claimed it… It left her breathless and in desperate need for him.

The beginning was always soft, but it didn't take long for that to no longer be enough.

His hands began their own exploration, wandering up and down her thighs. Klaus bit her lower lip sharply, just before sucking it between his own. Her fingers were soon buried in his hair, needing him closer. Needing more.

And when his fingertips found their way underneath her shirt and slowly made their way up and up until he had her breasts in his hold, squeezing and reshaping them… Her pussy was already soaking for him. She couldn't help but rock her hips against him, desperately needing the friction.

He pulled back. That damn smirk on his face.

"Tell me what you want, sweetheart. I need to hear you say it."

This happened often. Klaus loved having her talk about what she wanted him to do to her. All the ways she imagined him having her.

Caroline bit her lower lip, hesitating. It seemed so sinful to confess her fantasies to him, but… The idea of him indulging her was one that she rather enjoyed. The perspective of such sweet rewards won against any embarrassment she might have.

"I want your cock inside of me," she offered him tentatively, enjoying how his eyes immediately darkened at her words. "I want to be on my hands and knees for you while you fuck me."

The feline smile he gave her made her shiver.

Klaus reached out to pull the strap of her tank top down her left shoulder, caressing the bare skin with his fingers for a moment before he leaned in to kiss it softly. There was something about that intimacy that made her blood feel warmer inside her veins.

"That can very much be arranged," he said quietly.

She found herself with her back against the mattress a moment later, his lips on hers as his hands worked on getting rid of her cotton shorts and knickers. Her own hands began caressing his back, feelings his muscles with her fingertips, enjoying the way they tensed when she dragged her nails over them.

He was touching her inner thighs with lazy, languid strokes that made her spread her legs wide for him in the hopes that it would encourage him. She was no disappointed when his fingers trailed up until they were hovering over where she wanted him the most.

He pushed two of them inside her pussy without warning, and she moaned against his mouth as he began to move them. His soft and tender rhythm did nothing more than to frustrate her further, but at least he was touching her.

Caroline groaned when he pulled back from the kiss, but she couldn't really argue with him taking off her shirt… Not when his lips made their way to her breasts, sucking in her pebbled nipples, teasing the sensitive skin with his teeth.

Her back was arched, her hips kept chasing his touches… God, it was ridiculous how quickly he could turn her into a mess. She could not focus on anything that wasn't him. On the ways he was or would be touching her.

He helped her get rid of his pants, groaning when she teased him by grabbing his arse harshly.

Klaus offered her a wicked smile, his eyes shining golden.

"Allow me, sweetheart, the pleasure of giving you what you want."

She nodded hurriedly and, in half a second, she found herself on her hands and knees for him, spreading her legs invitingly as she waited for him to position himself behind her.

He brushed the tip of his cock against her soaking folds, making her cry out for him to stop teasing her. She just needed him.

Before she could find out if he would be merciful, though—

She woke up.

And that was precisely the issue… She'd always wake up.

Frustrated and tired and with her pussy dripping and aching for him.

For the first few weeks, she had tried to hold back from touching herself, but eventually her needs overcame her shame and sense of betrayal, and she'd try to find relief in her fingers.

Now not even that seemed to work anymore. Not when she kept wondering what his hand would feel like. Or his tongue. Or his cock.

It was in that state of desperation that she made the decision to attend the stupid ball he had invited her to. And it was only that state of desperation that made her agree with wearing the gown he had sent to her.

Still, no matter how creepy it was that he knew her measures… Walking into that room wearing that dress still made her feel like a queen.

Klaus noticed her the moment she stepped inside, and his eyes didn't leave her for a second after that.

It was hard to conceal the reactions her body seemed to have in his presence, but she did her best to hold his gaze as he approached her. She couldn't help but notice just how handsome he looked wearing a tux.

"Good evening, sweetheart. You look beautiful tonight," he said, his eyes scanning her body with a predatory gaze.

Caroline gritted her teeth at how pleased he looked that she was wearing his gift. "Thanks."

His lips stretched into a smile, and she knew in that second she had made a mistake in coming tonight. But looking at him, she did not have the strength to just walk away.

Before either of them could come up with something to say, it was announced that everyone should find a partner for there would be a waltz in ten minutes.

Klaus immediately offered her his hand. "It would be rude not to."

She rolled her eyes and scoffed, but placed her gloved hand on top of his. The thin barrier did nothing to appease the warmth she felt in her very bones at that moment. And maybe she was imagining things, but he looked at her as if he felt it too.

Any hope that she could not be too affected by him that night disappeared the moment he placed his hand on her waist.

Caroline wished she would not remember the dreams where she could feel the heat of his hand on her skin, but the memories invaded her mind without any consideration for her wishes.

She leaned into him, closing her eyes as his scent filled her lungs.

He thankfully stayed silent through their dance, but she could feel his tense shoulder underneath her palm. She knew that his silence wasn't out of pity or mercy, but because this somehow affected him just as much.

When she dared look at him, his eyes were almost entirely darkened, completely filled with lust. She knew they mirrored her own.

Her breath was caught in her throat, her lips slightly parted. What is happening?

"I need some fresh air," she said with a trembling voice as soon as the musicians stopped and the people began to applaud.

He nodded, though it took him a few seconds to let her go.

She was not surprised when he came to find her in the gardens only minutes later.

"Are you all right, love?" he asked, even if he knew the answer. Even if he was clearly not all right either, his skin flushed and hair disheveled.

Caroline shook her head, taking a few steps away from him and turning away. "What did you do to me? I can't… I can't breathe, I can't think… I can't sleep!"

She let out a humourless laugh that didn't sound her own.

He startled her when he slowly wrapped his arm around her waist, pulling her back against his front. Her body immediately responded by relaxing against him. She rested her head against his shoulder, a pleased hum escaping her lips as everything seemed to click into place.

"I get the dreams, too," he whispered against her ear, his lips brushing against her skin. "I go to sleep thinking of you. I dream of you. And then I wake up thinking of you… It's inconvenient, that's what it is. Every second of every day, I am consumed by this need. I want to have you. I want to claim you, my beautiful Caroline. My mate."

Her heart skipped a beat. Surely he couldn't mean-

"What did you say?" she blurted out.

Klaus chuckled as he tightened his grip on her. She wished that had scared her rather than enticed her.

"It's the most commonly used term to describe this. This… connection put in place by very ancient magic. I don't suppose you are familiar with the legends?" She shook her head. "Very well. It is said by most packs around the world that every werewolf is linked to another person on Earth. Someone to ground them. A weakness, if you will. Like vampires have the sun and wood and vervain. Some werewolves believe that mates are both a blessing and a curse. You see, they claim that you will know no greater bond, no greater joy than being with your mate. But yet, you'll need them as you need air to survive. This need, this aching for someone else… I'll never stop."

Caroline swallowed. She wasn't sure her lungs were working properly.

"You can't be saying that-"

"We are mates? Well, I am. It caught me by surprise, too, when I first realized it. I had not expected to find my mate so soon after freeing my werewolf side. It was not within my plans, you see."

She scoffed. "I'm sorry to be so inconvenient for you," she said, remembering his words from just moments ago.

She wasn't sure she should believe a word he was saying, but at the same time she couldn't help it.

She felt that connection he was mentioning it, could feel her need for him taking up the space between her bones and her muscles, settling uncomfortably there, like an itch she would never be able to scratch.

The discomfort eased each time she breathed him in. Even as he said, "I thought of killing you the first time I saw you. And I almost did it… But I realized that I couldn't do it myself. So I asked my hybrid to bite you, and I thought that would be it. Except I could not stomach the thought of you-" he shuddered, taking a deep breath before he continued. "You are so bright, Caroline. I recognized your fiery soul the moment I looked at you… And extinguishing that fire, that light… I couldn't do it. I will not do it."

Caroline released a breath she didn't know she had been holding. She knew that "well, apparently he won't kill me" was setting the bar a little too low, but she knew what it meant that a man like him was willing to have one more weakness just because he could not bear the thought of her dying.

That somehow made her feel powerful.

"So what does this mean for us now?"

"You could go home right now, try to be away from me for as long as the bond would let you. I wouldn't suggest trying to run away, though. I would follow you and I would find you."

It was both a promise and a threat.

"Or?" she prompted, feeling a little bold.

Klaus suddenly turned her around so that she'd be facing him. His trademark smirk was back in his lips. "Or you could tell me about your dreams."

Caroline felt a smile spread across her face. She wasn't sure what this would all mean in the long run, she had no idea about how she'd break the news to her mother and her friends. Hell, she didn't even know what being mated to Klaus would entail.

But two months of frustration and nearly being driven to madness because she couldn't have him made her a little reckless.

Instead of running away, she found herself saying, "I think I'd rather if you told me about yours."

Klaus arched his brows at her, accepting her challenge. He pulled her closer to him by her hips, leaning in to capture her earlobe between his teeth.

"Oh, sweet one, don't worry. I'll tell you every single one of my darkest desires after I've coaxed yours from your pretty lips."

A shiver ran down her spine as she thought about everything she had imagined for them and about all of the things that could've gone through his mind.

"A dream for a dream," she counteroffered, her voice weak as she grabbed onto his forearms.

He laughed softly against her ear.

"We will have so much fun, you and I," he mused, pulling back to look into her eyes. She could see the amusement in his.

Caroline didn't know what he meant and wasn't sure she wanted to ask. So she only pressed, "Deal?"

He smiled, taking a step back only to take her hand in his, bringing her knuckles to meet his lips. And as he looked up at her… She had never seen a more sinful gaze. It was thrilling to see the promise it carried.

"Deal."

So, what do you think about it? Did you enjoy the setting? Their dynamic? Caroline's dream? I know I was a little mean not to actually write the whole thing, but starting next chapter I promise I'll deliver on all the dirty details. So, starting from now, each chapter will be about Klaus fulfilling one of Caroline's fantasies (and vice-versa), and I'd love if you guys could send in some suggestions about what sort of things you'd like to read them do. You can send your ideas on my tumblr (itsnotacrimetoloveyou) or just on the reviews in the story. I can't wait to hear your thoughts about this and what might come next!
