I wrote this drabble for the Klarosexversary using a prompt that realynn8 had left me (so it's smut, of course): Klaus shows Caroline all the delights of bloodsharing.

There's some fluff and some humor and, of course, a whole bunch of smut! Enjoy ;)

Rated M

Her hands trailed down his back, the pressure of her fingers against his skin increasing as his thrusts picked up speed. She threw her head back in pleasure as he hit that perfect spot deep inside her, pulling a cry from her lips. Caroline felt his smirk against her neck as he continued worshipping her body, his hands teasing her sensitive breasts while she writhed beneath him.

"That's it sweetheart, don't hold back," he growled into her ear, tongue darting out to draw the lobe into his mouth.

She could only whimper beneath him as pleasure continued to build within her body, her legs wrapping tighter around his waist. She was lost to the sensations he created, her every sense feeling heightened. She could smell a mixture of sweat and sex and something that was purely Klaus. She could taste the bourbon on his lips and the salt of his skin. She could feel his smooth, soft skin beneath her fingers as his body pressed against hers in a sensual dance. She could hear his pants in her ear, his deep breaths betraying his exertion and enjoyment despite how effortless his words tried to make it seem. And she could see pure love when she looked into his deep blue eyes, something she knew he was seeing reflected back at him.

"Klaus," she moaned as his lips moved lower along her collarbone, her eyes falling shut. They flew open again, however, as soon as she felt the telltale sharpness of his fangs dragging along her skin. "What are you doing?" she gasped, pulling away to look at him in shock.

The hybrid looked at her curiously as he paused all action. "I would have thought it obvious by now," he smirked, thrusting forward in demonstration.

Caroline couldn't help the moan that escaped her lips at his movement, though she frowned deeply at him. "I meant with your fangs. Are you trying to kill me? Again?"

Klaus huffed, rolling his eyes indignantly at the suggestion. You try and bite someone to death one time and they never let you forget it. Alright, maybe he was responsible for another bite as well, technically, but still. "You know I would never do that to you, love. Again," he added bitterly at her raised brow.

"Mmm," Caroline acknowledged, knowing he really wouldn't. "Then what do you think you're doing?"

He just stared at her for a moment, trying to work out if she was trying to put one over on him before he realized she really didn't understand. "Did none of your friends ever teach you about bloodsharing?" he asked carefully, watching her face for signs of recognition.

"Oh, Elena told me about her and Damon doing that once I think," she said, her eyes brightening with understanding. "It's like personal or something."

Klaus restrained himself from rolling his eyes, biting his tongue so he didn't make disparaging remarks about the doppelganger and her Salvatore-of-the-month. "It's more than just personal, love. It's… intimate. More so than mere sex," he said slowly, waiting for it to register in her mind. "It heightens the experience, bringing you closer to your partner in a way you've never known."

She looked at him thoughtfully before responding. "So, it's special," she concluded, watching him for confirmation.

"Very," he nodded, glancing away for a moment before continuing. "I've… never done it with anyone before either," Klaus admitted, albeit reluctantly.

Caroline's gaze softened, her hand moving to cup his cheek. "Why?" she asked, meeting his eyes.

"It's not just intimate, it puts you at the mercy of the other person," he informed her, hoping he wouldn't need to elaborate further.

"Ah, and the Big Bad Hybrid would never put himself in that position," she teased, smirking up at him.

Klaus rolled his eyes before he looked down at her again, suddenly thoughtful. "Until now."

The smirk slipped from her face, touched by his confession. She pulled him down, her lips meeting his in a gentle, yet passionate kiss, pouring her feelings into the gesture. The hybrid was quick to respond, the heat between them quickly rekindling until he was once more moving within her, Caroline's gasps and moans filling the room.

When he bent his head, his fangs grazing her neck once more, she stilled for a moment before forcing herself to relax, though her grip on his shoulders tightened markedly.

"Is this entirely safe?" she panted, licking her lips anxiously even as the heat in her body rose at the feeling of his teeth on her skin. "I mean, your bite can kill me."

Klaus paused from his perusal of her neck to look up, meeting her worried blue eyes. "Only if you don't drink from me in return," he assured her. He paused to consider for a moment. "Would you like to go first, perhaps?"

Her eyes widened at the suggestion. "What?" she gasped, almost missing the way his hand snaked down between their bodies.

"If you bite me first, love, then you'll already have the cure in your system," he said, the words low and seductive and Caroline thought it odd that hearing him talk about werewolf venom was turning her on. "So when I taste you," he continued, drawing a cry from the blonde as his wandering hand found her clit, "you can focus entirely on how much it will make you want to scream in pleasure."

Caroline couldn't help groaning at that, the combination of his words and touch causing the familiar tightness at her core to increase. "Yes," she breathed as he continued to watch her, waiting for an answer.

His smirk was devious and full of wicked promises and Caroline couldn't wait. She pushed her apprehension aside as he tilted his head, allowing her full access to his neck. She could feel the veins spidering out from her eyes as she focused in on the throbbing vein in his neck, the sensation of needing to feed slightly different than usual, more… carnal. She brought his neck down to her, tongue laving over his heated skin before she allowed her elongated fangs to skim along his throat.

"That's it, sweetheart. Have at it."

Shivering at his words, as well as his talented fingers, Caroline gave in and bit down, her sharp canines piercing his flesh. She shared a moan with her lover as she felt the blood flow into her mouth, the same exquisite taste she didn't know she had been craving all this time. Her body seemed to be set ablaze as she continued to drink him, her arms holding him tightly in place, as if she was fearful he would leave and deprive her of his wonderful flavor.

She cried out anew as she felt his double set of fangs pierce her own neck, the sensation immeasurably more pleasurable than any other time she had been bitten by a hybrid. She felt her world falling away beneath her, leaving only her and Klaus, tangled together in a heated embrace, blood flowing from one to the other, sharing their very essences with each other. The enormity of the situation hit her then, even as the pleasure exploded around her in white hot flames. They were sharing not only their blood, their trust, but themselves, what they were at their very cores, and instead of being overwhelmed or afraid, Caroline reveled in it.

What felt like forever was really mere seconds and the pleasure of the bloodsharing came to a head until it shattered, throwing her into a mind numbing orgasm, his name torn from her lips as she was ripped away from his neck by the sheer force of it. She felt him follow her soon after, her own name a harsh growl against her shoulder.

Caroline lay there panting, unsure if she could even move when she felt his lips come crashing down on hers, the taste of their blood mixing on her tongue arousing her once more. After a few moments he pulled back, the blood smeared along his lips causing a shiver to run down her spine as she gazed up at him from underneath hooded eyes.

"What did you think, Caroline?" he asked, voice thick with his usual ego.

"Wow," she felt herself breathing out before she could stop herself, the grin on his lips growing obnoxiously large. "I mean, I suppose it was alright," she mused, smiling at his indignant scoff. "But I think it's only right to try again, you know, to be sure."

Klaus' lips quirked up as he regarded her carefully. "I think I can manage another demonstration," he said lowly before he suddenly grabbed her shoulders and flipped them over, causing her to yelp in surprise.

She took a moment to take in her new position on top of him before a very Klaus-like smirk crossed her lips and she began to move; and this time it was his turn to moan.
