AN: First of all, thank you for all the wonderful reviews on my last drabble! Your response was overwhelming and it means a world to me!

I know I've been a bit AWOL these last few weeks but I've been struggling quite a lot with my klaroline muse and well, my writing muse in general, actually. Hope this is worth the wait :)

All-human and NSFW. This is pretty much Porn Without Plot based on this prompt:

"Human klaroline smut involving one of Klaus' lines from the show. Klaus & Caroline have just finished an exhaustive sex marathon. Caroline says she can't take another orgasm. Klaus, still horny as ever, say "i'll take that as a challenge."

Caroline has quite forgotten how to breathe by now.

It doesn't help that Klaus is still buried balls-deep inside of her, the aftershocks of her latest orgasm leaving her skin sensitive and tingling.

They have come together this time, his gaze fixed on her as if he wished to learn all the ways her face contorts in this perplexing kind of pleasure that borders on pain. To register each flutter of lashes as he sinks deeper into her and twists his hips in a way that has her bite into her lips until they bleed.

She doesn't like the feeling that sets in her lungs after they've fallen apart together, the very one that leaves her so breathless. She prefers to think of how swollen and slick she is, her thighs sticky with their mixed release and how if she clenched her pussy around him hard enough, he could probably make her come again.

Because dammit, he's already semi-hard.

But it's getting late and they've had sex more times than she can count today and their rules clearly state - no sleepovers - so instead of initiating another round, Caroline says, "I need to go."

Klaus merely inches up a brow, a slight smirk curving those perfectly shaped ridiculous lips, "Oh?"

"It's late. And I have an early morning." A lie.

His tongue swipes along his lower lips as he ponders what to say next and then, his voice pours like honey over her skin, "You could stay here."

"Nope." Her hand presses against the chiseled planes of his chest as she tries to make her escape. "Besides, I couldn't possibly take another orgasm," she adds and the moment the words leave her mouth, she knows it's a mistake because -

Because there's this predatory glint crossing his eyes and an earlier smirk turned into a full-blown grin while his breath sets on her skin, warm and hot and burning as he rasps against her ear, "I'll take that as a challenge."

And Caroline knows he's serious, yes, Klaus does love a good challenge - they're the same this way, she gets it now, even if it's taken her a few years to understand it. Perhaps that's why no one else has ever made her toes curl quite the way he does or why nothing brings her more satisfaction than to see him fall apart under her touch.

From the devious twist of his mouth she foresees it will be her turn to fall apart this time. But damn her if she doesn't pick up this obvious gauntlet thrown under her feet - of course she will - so she whispers with a seductive lilt, "Do your worst."

"I fully intend to, sweetheart." He nips the skin at her hollow of her throat playfully, then pulls out of her in one swift move, tearing a drawn-out groan from her mouth, followed by a crisp "Fuck."

"Tsk." Klaus shakes his head in amusement as his hands dip lower, brushing past the curve of her breasts and then lower still. "Such a wicked mouth you have, love."

"You have no problem with my mouth when I suck you off," Caroline grits out, barely, because he decides to flick his thumb against her clit just then. She's still so wet and ridiculously sensitive from all their previous times and his touch sets her on edge right away even though she's a bit sore and spent.

But he's smart and he just keeps her there, at that frustrating point where she can feel the heat pulling in her belly and the next climax almost roiling in waves but it's a fucking almost, she's not there yet, even though his two fingers sink into her pussy and start thrusting.

In and out. And in. In. In.

"I never said I have, Caroline," he finally retorts, meeting her eyes. "In fact, I adore it. When we quarrel, when you talk. And when it's wrapped around my cock," he draws out that last word as he crooks his fingers, hitting her sweet spot and her back arches up - because fuck it, she needs more of his touch.

Klaus is nothing but attuned to her body language, to her and his lips start a journey, hovering just above her clit and Caroline shivers in anticipation because she wants, needs, craves to have him lick her there, and then suck - hard - until her throat is raw from screams and her muscles shake. Klaus has other plans though and when he moves higher, she signals her frustration with a strangled moan. But his lips are relentless as they wander up and latch onto her nipple, tongue laving around the bud 'till it's painfully tight, all while his fingers slide in and out of her.

She's lost in sensation by now and her body's quivering as she can feel her release building up and up, only for his touch to soften, for the pressure to lessen. Her hips jerk frantically against his fingers to get more friction but it's no good, she needs something else, just more and harder and rougher to tip her over the edge.

"Klaus!" she lets out a guttural groan.

His teeth graze her nipple before he murmurs with feigned innocence "Caroline?"

"Make - " she bites into her lips as his thumb strokes her clit again, "me - " He sucks on her collarbone, holding her gaze and then she finally manages, "come!" Pushing her hips against his hand, she clenches her thighs and adds, 'Right now."

There's this one second when Klaus looks at her and she thinks he's going to tease her forever, tease her into spending the night because it just tugs at her ambition now and it's a point of pride to have this fucking orgasm. There's this one second when the familiar playful glint is gone from his eyes and they fill with something different, something warmer and dangerous and her breath hitches in her throat again but then, oh then -

His head dives low, between her thighs and he laces her legs over his shoulders. Her hands fist into the sheets because he's there, tongue swirling around her clit and her skin is flushed and prickling with need. She knows she'll probably be sore as hell tomorrow but that's of no importance now, the chase to that glorious feeling of falling apart is all she can think of right now. Craning her head up a bit, she fixes her stare on Klaus, his dirty blond curls a tousled mess between her legs.

A gasp passes through her mouth as his tongue slides into her, languid licks and rough moves that leave her legs trembling around his neck. His nose brushes against her clit and fuck if she knows how he can go down on her for so long with no break for air.

Must be that college swimming team experience finally paying off - she muses before that last flicker of tongue renders her unable to think. His name falls off her lips before she can control herself but who is she kidding?

There's no controlling herself when her body finally reaches and tips over that point, the one where she shudders and throbs and heat spreads through her in waves.

Slowly, delicately, Klaus pulls her lax limbs off his shoulders and nestles himself in the cradle of her thighs, peppering feather-like kisses along her neck, under he jaw, in the corner of her mouth.

The scrape of his stubble against her cheek is the last thing she remembers before she falls into the treacherous arms of sleep.

AN: So how did you like it? Hot or not? Would you like to read more of this universe? This is a standalone drabble but it can also be seen as a sneak peek to Friends With Benefits College/Office AU that I've been planning for some time. What do you think?

Thank you for reading and till next time (hopefully sooner)!
