Day Four. For LuLu. And it's extra long because I put if off for so long. Enjoy, readers. It's a "spanking" good time.

Your presence is required in Mr. Mikaelson's office directly after practice this evening.

Caroline reread the note in her hand with distaste for the tenth time, shaking her head as her heels clicked against the tile, the sound echoing throughout the hallway.

That stupid hybrid was pushing it this time.

It was one thing, showing up unannounced as the new Art History teacher, a devilish smirk on his face and exuding a smug sense of accomplishment at her look of surprise. It was one thing, treating her as no more than another adolescent schoolgirl, all the while relishing in her discomfort and annoyance.

It was one thing, being the bane of her existence.

Him actually behaving like she was going to respect his so-called authority in this instance was another thing entirely.

Tossing her curls over her shoulder, she rounded the isolated corner towards the art room, rolling her eyes when she caught sight of him behind the massive desk, his head buried in a stack of papers in his hands, pen dangling from his fingers as his eyes scoured the written words before him.

She stepped inside, crossing her arms over her chest.

"Shut the door, please," he instructed, not even sparing her a glance as he made a note in the margin of the paper in his hand.

She rolled her eyes, but did as she was told, closing the door with a quiet click before turning back to him and making her way towards him. His gaze remained on the paperwork, the only indication he even realized she was still there being the smirk that was slowly stretching across his face, blossoming into a grin when she huffed impatiently.

"You know, this whole teacher act you're playing right now? It's really ridiculous," she said, crossing her arms over her chest as she shifted her weight on her feet. "Seriously. You're taking the whole overbearing boyfriend role a little too far."

Klaus' eyes raised at her words, one eyebrow arched as he took her in. "You do realize that the way you're speaking to me right now, Miss Forbes, is completely unacceptable?"

Caroline groaned, stomping her feet. "Klaus, I'm serious! This is ridiculous. Just because you're all paranoid and incapable of actually believing that I can handle myself, is no excuse for you doing this. My relationship with Elena is finally improving, and she was finally coming to terms with the fact that we're together, and that has a lot to do with the fact that I promised her the two of you would never really interact. And you, being here, every freaking day now? All of my hard work is going to be completely useless now."

He'd been smiling at her as she ranted, slowly rising from his seat and coming around the desk. He grinned when he saw her gaze falter at his approach, hearing her breath hitch the slightest bit when he stalked around her.

"Do you honestly think," he asked softly, reaching out and slowly pulling her hair to the side, his lips barely grazing the sensitive skin of her neck. "That I give a damn about the doppelganger and how uncomfortable she might be with me here?" He felt her shudder as he pressed a gentle kiss to the nape of her neck, and he smirked when he sensed the anger slowly leaving her body. "I had to keep an eye on you somehow, love…your knack for getting yourself into trouble is uncanny."

She scoffed, shaking her head, and he chuckled, his hands grazing the thin strip of skin that was left exposed between her tank top and skirt.

"Really, Caroline…is Elena Gilbert the true reason I'm facing your ire at the moment? Or could it possibly be because you actually enjoyed me being here this afternoon."

"What?" she asked, crossing her arms over her chest, telling herself it was to display her anger at him and not a means to stop herself from reaching for him. "Enjoy you being a psycho, overbearing boyfriend?"

He laughed behind her, his breath warm on her neck as his lips trailed a path to her ear. "Come now, Caroline…do honestly believe I didn't have an eye on your face the whole time?" He stopped behind her, one hand cradling the side of her neck, the other wrapping around her waist, pulling her back against him. He moved his hips, grinning when he heard her sharp intake of breath when his arousal pressed firmly into her backside. "You don't think I saw the fire in your eyes when I stood in front of the room? Saw you stripping off my tie…my shirt…all the while in the back of your mind wondering how quickly you could empty the room so I could bend you over the desk."

Caroline shuddered underneath his sensuous touch, his lips grazing the skin of her jaw and neck. She wouldn't admit to him just how true his words were. While initially she'd been furious about his overstepped bounds—and honestly a bit surprised to see him take to such levels as intermeshing himself with the "mindless dribble" that populated her high school—she'd been unable to stop herself from ogling him from the back of the classroom. Watching the way his button up shirt stretched across his chest every time he moved. The way he'd run his hands through his already disheveled curls each time he took to pacing the length of the room as he lectured. How his eyes would linger on her, a familiar fire burning within them. That familiar aching in her core had taken root, making the 45 minute period drag on and on.

She bit her lip, trying to ignore the heat that was quickly traveling to the apex of her thighs as his fingers crept under the hem of her shirt, dancing across her abdomen. "Someone's awfully full of themselves," she said softly.

He tightened his grip in return, humming under his breath when she whimpered quietly. "You'll be full of me soon enough, love," he whispered harshly into her ear, his hand slowly sliding under the waistband of her skirt, tracing the lacy edge of her underwear. "Just as soon as you admit," his fingers easily slipped beneath the thin material, "that every time you had to call me Mr. Mikaelson today," he teasingly circled her clit, feeling her shudder against him, "you wanted to shout it while writhing underneath me." His fingers slid between her wet folds, outlining her opening as his free hand came to wrap around her chest, holding her against him.

"Klaus…"

He dove two fingers into her, her voice crying out as she felt her knees shake. He pumped in and out of her at a slow and steady pace, his finger curling and grazing that sweet spot that left her gasping. Her nails dug into the flesh of his arm as he wrapped it around her chest, holding her tightly against him and keeping her upright.

Caroline closed her eyes against the onslaught of pleasure that assaulted her body, his fingers working her over in the way she knew he was an expert in now. She refused to submit to him. She wouldn't admit the fantasies that had ran through her head that afternoon. The image of him bending her over the side of his desk, her skirt around her hips, his cock driving into her at a furious pace as she moaned and clawed at the oak wood. The excitement she had felt when she imagined what it would be like to carry on a taboo affair with her new teacher—heated glances, lingering touches, dirty whispered promises in the hallway.

She whimpered when his pace quickened, her orgasm looming just over the horizon…

Suddenly he stopped, his fingers sliding out of her quickly, her gasp of shock and outrage at a climax unfulfilled cutting off when in a rush of wind she was propelled forward, her body slamming into the edge of the desk before them. She caught herself, bracing her hands against the solid mahogany. He was behind her, one hand braced on her back, keeping her bent over as he made quick work of her panties, the fabric ripping as he tossed it to the side. She felt a shiver go through her when his hand gently caressed the curves of her ass.

"Insubordination in a student, Miss Forbes, is quite a high offense," he said, leaning over her, his lips brushing the shell of her ear. His hand slid down and between her legs, his fingers teasing her aching nub as she whimpered beneath him. "I'm afraid a reprimand is in order."

Caroline's stomach leaped with excitement and nervousness as his hand continued to stroke her. Before she could even let out a whimper, the hand on her back retreated, and then a loud slap resonated through the room, in time with the sudden pain that spread across her backside. She yelped, her fingers digging into the wood beneath her hands.

His hand was rubbing a soothing pattern against her stinging flesh, his eyes watching in delight as the creamy white skin of her backside turned a delightful shade of pink. He hummed under his breath, letting the hand that was caressing the skin of her inner thigh slide up, his fingers softly trailing the length of her folds.

Caroline gasped, burying her face against her hand, concentrating on the feel of his calloused fingers stroking her; circling her aching nub before diving into her wet heat. His thumb pressed against her, his fingers starting a slow rhythm once more, and then she winced when his hand came down on her again, this time on the opposite cheek. Heat spread through her, the mixture of pain and pleasure suddenly clouding her senses as his hand came down again, his fingers still working a steady rhythm between her thighs.

A slap sounded again, and she groaned when her walls tightened around his curling fingers. "Jesus, fuck," she shouted, her hands gripping the edge of the desk. "Dammit, Nik, would you just fuck me already?"

His cock twitched in his pants at the sound of such foul words escaping her lips, and he pulled away from her, making fast work of his belt and shoving his pants down to his knees. He leaned forward, propping his hands under her hips and tilting them up, and then he was groaning as her wet hot heat enveloped him like a glove. She cried out under him, the sound of her nails scraping down the surface of his desk reaching his ears as he reared back and slammed into her again.

He leaned over her, bracing one hand against the desktop as he used the other to hold her to him. She was moaning under him, her hips bucking back to meet him thrust for thrust. Her upper thighs slammed into the edge of the desk with every motion, the biting pain mixing with the unmeasurable pleasure that scorched her body as his cock stretched her inside out.

Klaus gritted his teeth as he pounded into her, wrapping an arm around her as he pulled her flush against his chest. His hand slid beneath the hem of her shirt, his fingers slipping under the material of her bra and cupping her breasts, teasing her nipples as she moaned against him. He groaned into her ear, his other hand sliding down to where their bodies were joined, rubbing a furious rhythm against her throbbing clit.

Her hands clutched at his arms, her teeth biting into her lip to stifle her cries. She could feel that fire spreading through her—the fire that she had never experienced until Klaus' skilled body moved against hers. His cock slammed into her again and again, the sound of their slick flesh slapping against each other seeming to resonate through the classroom. There was an excitement in this—fucking so passionately with the knowledge that any passing student or teacher could glance in and catch their forbidden act.

She smiled when his grip on her tightened, his fingers working at a furious pace between her legs as he moved in and out of her. She could feel her orgasm looming. She closed her eyes, concentrating on the feel of his hands and his body moving behind her, and then she was crying out in ecstasy, her body shuddering and shaking as she exploded around him.

The smell of her climax overpowered his senses then, and he growled low in his throat as he slammed into her, his own orgasm bursting forth and spilling into her. They gasped against each other, their bodies slumping onto the desk before them as they caught their breath.

Klaus pressed a loving kiss into Caroline's damp hair, feeling her sigh contently beneath him, and he smiled into her skin.

"And how, exactly, is what we just did an appropriate student-teacher encounter, Mr. Mikaelson?" she murmured, smiling when he chuckled.

If all of their after-school meets ending like this, maybe this was an arrangement she could get on board with.

Feel free to shoot me some smut scenarios you all would enjoy. I'm sure LuLu will enjoy any and all of them!
