Disclaimer: I do not own The Vampire Diaries or The Originals. Sadly. However, I do own a recipe for chocolate chip cookie dough brownies that will take you to the heights of pleasure that occurred for me when I first discovered The Vampire Diaries before its writing became a tedious embarrassment.

Warning: The following content is for mature audiences only. It features Caroline and Klaus and Enzo in a spectacular, debauched threesome. Fluids and fornicating and fun. Oh my.

Author's Note: In this world, Klaus and Caroline had sex and he still went to New Orleans. No crazy Hayley story line though. Caroline and Enzo have maintained a flirty relationship, but this will be the first time they explore this further.

An Experiment

"College is a time for experimentation. A time to cast aside the rigid expectations of what is expected of you and embrace endless possibilities." Caroline confidently began. She maintained eye contact with them, wanting her intentions to be clear. "That's why I invited you here. To be a part of my experiment."

"Experiment, love?" Klaus asked, arching an eyebrow.

"Really, gorgeous, if you want an excuse to get it on again with the hybrid, what am I doing here? Holding up score cards?" Enzo laughed.

Caroline put her hands on her hips, exasperated by her companions. "You are here in my dorm room because I've come to the conclusion that nothing is ever certain. Look around!" She gestured to the sad, empty beds. "Since I was a kid I had planned out every aspect of my life meticulously. I was going to be head cheerleader and prom queen and attend college with my two best friends and share a dorm room together and then we would meet incredible guys who would love us and marry us and we'd have beautiful babies and live next door to each other and all grow old together and be blissfully ignorant of how much the world totally sucks." She huffed, rolling her eyes. "Obviously life had other plans. Nothing has turned out as I thought it would and I'm tired of not feeling like I'm in control of my fate. From now on, any small sliver of happiness I feel, I'm grabbing it with both hands because with my luck, someone will just torture it all away before I can enjoy it."

Klaus shook his head. "I'm still not clear on where we come in, sweetheart."

She stepped forward, reaching out for his hand. "You're here —" She paused to reach out with her other hand to grab Enzo, tugging him closer to her and Klaus. "And you're here because lately, the only times I can recall being happy have been the moments that I have spent with both of you. I don't know what my feelings mean and I'm still not ready to sort through everything, but I do know that I'd very much like to be with you both." She licked her lips hesitantly. "Here. Now."

Enzo cleared his throat, running his hands through his dark hair. "Are you serious, gorgeous? Once you do this, you can't take it back."

"Nervous, mate?" Klaus smirked. "Not sure you're up to the task?"

Caroline placed her hands on both of their chests, effectively stopping the argument before it could begin. "No. None of that. You are both here because I want both of you. If we do this, there will be no weird macho rivalry and alpha male comments to try to assert your dominance."

"Any other rules, love?" Klaus asked, tenderly tucking one of her blonde curls behind her ear.

"Yes." Caroline paused, willing herself not to respond to Klaus' electric touch until she finished her well-rehearsed speech. "We only go through with this if everyone is on board with the program. I like you both. While I don't know what this will mean for our future, I do know that I've thought about it for far too long to just ignore what I feel any longer. We just go with what we feel and not worry about what happens next. If someone isn't comfortable with something, speak up. Otherwise, just enjoy it."

She sighed, nearly melting as Enzo began trailing his long fingers down her bare arm. "I'm willing to play by your rules." He whispered, clearly challenging Klaus with a look.

"Of course, sweetheart." Klaus kissed her cheek quickly, savoring her intoxicating scent. "It would be my pleasure to join your 'experiment'. You smell divine, by the way. Almost as though you're already on the precipice of release." He dipped his head down again, thoroughly kissing her as she clutched his broad back helplessly.

She was so caught up in the ferocity of the kiss that she didn't see Enzo quickly discarding his black t-shirt and jeans, moving behind her to bunch up her green tank top before suddenly ripping it away. He softly caressed her ivory skin, raining down delicate butterfly kisses that left her moaning into Klaus' demanding mouth.

As Enzo pulled her back against him, she realized that he was completely bare and she flushed in excitement as she pulled away from Klaus briefly to pull off his gray Henley. Klaus pulled her back in for another passionate kiss, growling as her nimble fingers began tugging at his belt and unzipping his jeans. She pushed them down, gasping when his erect member brushed her quivering stomach.

"You're overdressed, gorgeous." Enzo whispered in her ear. "Let me help you with that." He grabbed her green-striped yoga shorts, pulling them slowly down her toned legs. He stayed on his knees behind her, his strong hands sliding over her round bottom, cupping her firm cheeks. Without warning, he began a series of light smacks, making her moan and clench her thighs.

Klaus broke their kiss, grinning in delight. "Oh, love, I can smell how much you enjoy being spanked." He briefly slid his tongue down the side of her neck, pausing to fondle and suck at her nipples until they were hard little diamonds against his delightful mouth. "I think further inspection is required." He smirked, catching her blue eyes in a heated gaze before suddenly dropping to his knees before her. He tentatively ran a finger across her moist center, sucking in a breath as he gathered her wetness. He pulled back his finger and never broke eye contact with her as he placed his finger in his mouth, reveling in her taste. "Magnificent." He declared, and then leaned down to carefully lap at her delicate lips, dripping with her arousal.

Caroline was on sensory overload and Enzo continued smacking her ass, which in turn drove Klaus' tongue deeper into her folds until his tongue plunged into her warm channel, making both of them moan in ecstasy.

"You don't know what that sound does to me," Enzo rumbled, suddenly stopping his light spanking and planting a firm kiss on her right ass cheek. His lips trailed across her bottom, lingering here and there as he used his tongue to further mark her soft skin, rosy from his earlier assault. He slid his tongue to her cleft, experimentally dipping inside.

"Yes," Caroline breathily said. "More!" She called out, clenching her ass cheeks against Enzo's tongue.

Elated by her encouragement, he ran his tongue the length of her cleft, groaning at the intense smell and flavors of her excitement. "Are you wet enough, gorgeous?" Enzo muttered against her ass, softly nipping her flank. She whimpered in response, continuing to ride Klaus' determined tongue. Enzo spread her ass cheeks and slowly pushed one finger into her tight hole. She gave a startled grunt and contracted around his finger, moaning at the foreign sensation. He carefully explored her crevice, sliding easily with the lubrication of her sweat and his earlier exploration.

"Faster," She commanded, not sure if she was directing Klaus' talented tongue or Enzo's thrusting finger. Both men increased their pace, thrusting into her as she was pushed and pulled between them. She stiffened and screamed out as white hot pleasure coursed through her body as she came.

Trembling in their arms, she allowed herself to be scooped up by Klaus, with Enzo growling in protest. She shot Enzo a warning look as Klaus laid her on a bed. "Be nice, Enzo. Just for that, you have to sit this one out and watch." She crawled on her hands and knees toward the edge of the bed where Klaus stood before her, his stiff erection proudly jutting forward. "Is that for me?" She asked, fluttering her eyelashes up at him.

"Always." Klaus sighed as Caroline's sweet lips wrapped around his tip, sipping at his smooth skin slowly. She rolled her tongue gently across his engorged veins, savoring in his masculine musk. In the corner of her eye, she caught Enzo as he slowly began stroking his hard member, following her movements perfectly, clearly imagining that she was kneeling before him. She sucked Klaus's flesh further down her throat, reveling in his obvious enjoyment and rapidly fluttered her tongue all around his cock.

"Just like that, sweetheart." Klaus groaned as he gripped her flaxen curls. "Fuck! Lick me." He panted.

She increased her pace, grabbing his base and caressing it as she continued her ministrations. Enzo had kept up with her, fisting his erection and moaning as he watched Caroline working over Klaus.

Klaus breathlessly warned, "Love, I'm going to come."

Caroline smiled as she licked his entire trembling length. She pulled back from him slightly. "Then come on me, Klaus." She confidently commanded.

"Fuck" Klaus grunted, gripping his penis and brushing it against her bouncing breasts, ejaculating onto her firm globes until he was completely spent, gasping harshly.

Enzo came immediately after, declaring, "Fuck, that was unbelievably hot, gorgeous." He walked cautiously toward the bed, uncertain if she was finished punishing him.

Caroline watched Enzo in amusement, but secretly ached for him to be inside of her. "Would you like a treat, Enzo?" She lay down on the bed and smiled up at him.

He eagerly scrambled onto the bed with her. "God, yes."

She casually flicked one of her nipples. "What would you like to do?"

"You." He bluntly said without hesitation.

"I want that too." She agreed. "But first, would you help me get clean?" She innocently asked, tugging on her nipples.

Without hesitation, Enzo straddled her waist and began furiously lapping at her breasts, his warm, wide tongue cleaning Klaus' excitement from her smooth skin.

Caroline cooed with pleasure, catching Klaus' intense stare and licking her lips. She loved that he was watching her without judgment; the fire that he felt for her was both obvious and immensely arousing. She gripped Enzo's dark locks and pulled his ear to her lips. "I need you inside me." She whispered.

Moaning, Enzo slid down and grasped his stiff cock, rubbing it against her labia and teasing her pleasure center. Without warning, he thrust into her cleanly, and began pounding in and out at a furious pace. "You're so tight." He groaned.

Klaus moved to Caroline's side, reaching out to tenderly tweak her nipples. His soft touches contrasted sharply with Enzo's rough riding, and she screamed out in pleasure, not knowing which man was pleasing her more.

She could feel Enzo getting close, and knew that she would need another push before she could orgasm again. With a grunt, he finished inside of her, pulling out to coat her soft thighs in his essence. He stood up, noticing that Klaus was ready for action once again. She was delighted that the boys were learning how to share and would pocket that observance for later when she could reward them properly. "Klaus," She whispered. "Can you make me come?"

"As you wish, sweetheart." Klaus purred, grasping her hips as his tongue lapped at her inner thighs. He slowly slid his cock into her quivering channel, still slick from Enzo's pleasure. He pressed his thumb against her clit, rubbing gentle circles while he rolled his hips in a seductive rhythm.

She was so close to the edge from Enzo's actions that she felt her desire coil within her center. With a sharp thrust, Klaus brought her to orgasm, feeling her thoroughly drench his penis. He groaned as he felt her let go, and it triggered his own satisfying finish.

With a sigh, she stretched out on her bed, gazing up at them both through eyes hooded in desire. They surprised her by each grabbing the other two beds and pushing them up against the one she was laying on, effectively creating a soft space for them all. They rested on either side of her, reaching out to softly caress her flesh still slick with sweat. "Would you like to play?" She asked, glancing at both. Her blushing cheeks intrigued them and they eagerly nodded, excited to see what naughty idea she had in mind. She flashed out of the bed and started rummaging through her closet until she found what she was looking for. She returned to the bed, biting her lip nervously. She held out the small pink vibrator and shyly asked, "Could Enzo try it on me, first?"

She had fantasized about them both when using her toy, and desperately wanted them both to play with her. To her delight, both seemed eager to accommodate her request, and Enzo gripped her toy, smirking as he played with the dials. "How do you want it, gorgeous?" He asked.

"Slow and dirty." She smiled at him slyly. "I want you to get me off and then finish inside me."

Enzo licked his lips. "Yes ma'am." He began with the slowest setting, trailing the tip up her thighs, tickling the sensitive skin.

Klaus leaned over and kissed her mouth possessively. "Spread your legs, love." He commanded, lazily tracing her ear with his sharp tongue.

She moaned as she obeyed Klaus, moving her legs to accommodate Enzo's ministrations. He swiftly turned up the speed and teased her vaginal lips. He dipped the tip inside, and groaned as her walls tightened. He pulled out her toy and dangled it before her mouth.

Klaus smirked. "Taste yourself, sweetheart."

She wrapped her tongue around the toy, humming in delight at the pleasant vibration. Enzo gently tugged it from her swollen lips and placed it back at her opening. He turned the dial higher and pushed it inside, starting a pleasant rhythm that made her buck her hips enthusiastically. Soon, she was on the edge of another orgasm, and sensing her urgent need, Enzo pulled out the toy and swiftly thrust his member into her.

Not one to be idle, Klaus paused sucking on Caroline's neck to grab the toy. He turned down the speed and brushed it across her nipples, thoroughly enjoying how her silky skin twitched in response.

Caroline moaned as Enzo grasped her ankles and rested them on his muscular shoulders, sinking deeper into her moist center. Grunting, Enzo felt her clamp tightly around his cock, pulsating as she came. He quickly followed her, his spasms filling her with liquid desire. Enzo rolled off of her, kissing her lightly on the lips. "That was fantastic, gorgeous."

Klaus casually twirled the pink toy in front of Caroline. "How about another round, love?"

Caroline sighed in contentment. "What did you have in mind?"

He grinned maliciously. "You'll see." He pulled her up, positioning her on all fours. As he moved behind her, he murmured, "I haven't gotten to enjoy this view yet." Klaus' tongue quickly darted out, licking a path through her cleft and swirling around her puckered hole. "Mmmm. You're soaked," He declared.

Enzo stood up from the bed and moved in front of Caroline. As he reached down to stroke himself, she asked, "Can I taste you?"

With a cheeky grin, he leaned forward, allowing her to delicately lick his tip.

As she flicked her tongue around his awakening member, she felt Klaus move her toy near her cleft. He brushed it along the twitching seam, flicking the dial to a higher speed and groaning in enjoyment as her ass cheeks began clenching.

Enzo flexed his toned hips, pushing more of his stiffening penis into her waiting mouth. As she began sucking him, she felt Klaus brush the tip of her toy near her trembling hole. Her desperate moans were all the encouragement he needed as he slowly pushed in the length, the soft vibrations rocking her body and leaving her giddy with want. She pushed her hips back against the toy, silently begging for Klaus to increase his thrusts. As he picked up on her cues, he growled in excitement, pushing the toy in faster.

Suddenly, Klaus cast aside the toy and thrust his solid member, already dripping with his arousal, into her waiting center. He groaned at her tightness, grabbing her firm ass cheeks and thrusting himself in further. She moaned at the intense feeling, causing pleasant vibrations around Enzo's cock, and with a startled yell, he shot his seed down her welcoming throat. As she swallowed everything he had to give, she felt herself release onto Klaus' swollen flesh.

Klaus grunted as he finished inside of her, swiveling his hips as he spent his remaining arousal onto her skin.

Collapsing in a sweaty, sated pile, they caught their breath, taking turns gazing at each other. Caroline hummed in contentment. "Best experiment ever. But we will need multiple data samples to solidify our findings." She smirked at them both. "Are you up for it?"
