The holidays could be the most bittersweet time of the year. Observing everyone with their friends and families without having your own was lonely and often damaging. You usually could go home for the holidays, see your loved ones, or sleep in at your childhood home, but not this year. This year, because of all the shit happening in the French Quarter, you were forced to be alone.
You hated every second of it.
But, being the go-getter you were, you decided to make the most of it. And you involved the Mikaelsons in this scheme (they were part of the reason you were stuck in this mess anyway).
You had dragged Kol with you to get a Christmas tree. More like, Rebekah had convinced him to go with you. You harbored a massive crush on the original vampire, and Bex, your newest friend, was fully aware of it. It’s why she engineered him to spend more time with you. He helped drag the tree to your tiny apartment and lounged on your couch like a cat as you finished setting it up and dragging out your holiday ornaments.
“Should I go for a color scheme or just hang up whatever?” You asked Kol, holding up a box of white and gold ornaments. He was posed on your couch like a Greek statue, hand thrown over his eyes and legs sprawled out like he couldn’t give a damn. He opened one eye to look at your ornaments. You held up your box of random accouterments, including an abominable snowman and a glittery baguette ornament.
“I like the random ones,” Kol mumbled, laying his head back and letting out a sigh like the world was oh so cruel.
“Am I boring you?” You chastised, a frown marring your features.
“Darling, you could never bore me,” Kol coos. “I just find this to be obtuse.”
“What about it is obtuse?”
“When will you get to enjoy all of this?” Kol finally sat up, gesturing to your apartment. “With everything going on…you’d be lucky to have a Christmas.”
You deflated at his words, clutching your box of ornaments between your hands. Kol was right, but you loathed it. You wanted to just have a holiday, that was all.
He took notice of your somber mood and got off the couch to crouch in front of you.
“Don’t worry, Y/N,” he sighed, picking up an ornament and hanging it on the tree. “Maybe I’ll be wrong.”
He wasn’t entirely wrong; you wanted to hate him for that. But you never could, not really. You spent your whole life feeling like you were holding your breath, but it was like you could actually breathe with him. He made you smile and also frustrated you to no end. Kol saved your life once, and you wondered there and then if it was physically possible to give him your heart. You never figured that part out.Later that week, you were at the Mikaelson compound preparing for a war meeting slash holiday dinner. Dinner was your idea, and Elijah backed you up. Some poor soul they compelled was likely making you food as you sat on Rebekah’s bed, flipping through a book.
“Did you ever have any holiday traditions?” You asked the blond, not looking up as you spoke. You could hear her rifling around at her vanity when she turned to you.
“Bonfire,” Bex answered. “We’d write our wishes and throw them in the fire.”
“We should do that!” You exclaimed, looking up at her. She chuckled at your excitement, even as a melancholy look crossed her features.
“What would you wish for?”
Rebekah took a beat.
“My family, together, at peace,” she said softly, looking down. You repositioned yourself to sit at the end of the bed, looking at her sadly.
“I won’t leave you, you know,” you murmured. “Even if I should’ve hit the hills a while ago.”
“I know that, dove,” Rebekah sighed. “You’re as much a part of this family as I am. I’m…grateful for that.” She tucked a strand of hair behind your ear, and you were hit by the realization that she was just a girl in a woman’s body. “Because you’re my family, I know exactly what you’d wish for.”
“Oh?” You lifted a brow at that.
“For someone to meet you under the mistletoe,” Rebekah teased, getting up from her chair and tackling you down on the bed in a fit of giggles.
“I have no clue what you’re talking about,” you gasped between laughter.
“Oh dear, Y/N, if only you could acknowledge how much he cares,” Rebekah sighed, and you poked her on the nose before rolling out of her reach.
“Don’t tell lies, Bex, it’s cruel,” you chastised.
“Is my darling sister being a vixen again?” Kol called from the doorway, catching both you and Rebekah’s attention. He leaned up against the door, arms crossed and a smirk on his face. You felt your heart rate pick up as you took him in.
“What do you want?” Rebekah inquired, looking bored.
“Dinner is ready; I came to fetch you,” Kol smirked, giving you a wink that sent your heart spiraling from the stratosphere. Rebekah grumbled and got up, pushing past you and out the door. You moved to follow, but Kol grabbed your arm, pulling you back towards him.
“Kol,” you breathed, looking up at him in question.
“Do I scare you?” He asked, peering at you.
“What?”
“Or is it nerves?” He traced his thumb over the vein on your inner arm, and you could swear he was listening to how your heart thumped. “What makes your heart jump every time I come around?”
“I get startled,” you stutter, ignoring the look in his eyes at your lie. Kol hummed, tucking a strand of hair behind your ear as his fingers traced your face.
“You know what I loathe about you?” Kol whispered. “You smell too sweet to resist…”
You wondered what would happen if you dared to kiss him right then, but the timing was never your forte, and you were interrupted by Rebekah yelling at the two of you to hurry up. You pulled yourself away, holding your breath, hoping to calm down as you descended the stairs. You could feel Kol following behind you.
Dinner was extravagant, as most things in the household were. You gored on rotisserie chicken and baked brie, letting the flavors coat your tongue. Elijah and Klaus bickered back and forth about a course of action with fighting the witches (they wanted Hope, of course). You could have been more helpful in these discussions anyway. Frankly, you weren’t sure why they kept you around. Maybe one day you’ll find out.
Dinner was interrupted by an explosion.
You felt yourself fly back, hitting the floor in the dust. The enemies had effectively retaliated, and the Mikaelsons fought back perfectly with tooth and claw. You brought yourself to a standing position, coming eye to eye with a witch who looked at you like you were a pawn on a chessboard. You sucker-punched her before she could make a move.
The Mikaelsons dealt with the threat in record time, and when the dust on their battlefield had settled, the arguments started. First, Klaus ranted about how they should’ve been more prepared, and then Elijah tried to explain how they made logical choices up to this point. Rebekah would occasionally butt in.
You just stood there hearing the noise build up in your head. You had the vague sense that you were bleeding, but you couldn’t find it in yourself to care. Someone came up next to you, and you turned to see it was Kol. He said something that you didn’t hear before biting his wrist and holding it up to you. You tentatively took it, letting his blood coat your throat before pulling away. The ringing stopped, and you felt your body stabilize.
The pressure from the family screaming match didn’t go away, though. Someone yelled, “Stop,” and everyone turned to look at you. You almost didn’t recognize your own voice breaking the chaos.
“Just stop,” you pleaded. You looked at each sibling, forcing them to really see you. “It’s the fucking holidays…why is there always fighting? Why are you always fighting?” Your voice broke. “You have each other, and you care so much even when you pretend you don’t, and you’re always fighting.”
“I would do anything to have my family right now, but I don’t, and it kills me,” you choked. “You guys have each other, and what do you do? Nothing. Nothing at all.”
You don’t know why you broke, but you did. Being alone during your favorite season hurt you way more than you let on. It felt like looking from outside your body as you walked out of the compound on the way home. You entered your apartment silently, flipping on the lights to absolute silence.
You took a shower and went out in pjs, bundling yourself up in front of your fireplace. It was one of the amenities that sold you on the apartment. You wrote out your wishes on a piece of paper, folding them into paper cranes (for the sake of being dramatic) and tossing them in the fire. You sniffled, hugging your knees to your chest and weeping. You missed home and your family. You felt terribly alone.
On your paper cranes, you wrote for your family, for being surrounded by loved ones during the holidays, and Kol liking you back. Simple, trivial wishes, but ones you had nonetheless. You debated calling it an early night when you heard a knock on your door.
You got up slowly to open it, recoiling in shock when Kol bounds in with Klaus following behind him. Both are wearing Santa hats.
“Mother of God—“ you curse, watching as Kol drops boxes of decorations on your couch and Klaus makes a beeline for your kitchen. “What are you doing here?”
“Celebrating Christmas,” Klaus says, pouring himself a drink (somehow finding your alcohol).
“What?”
“Elijah and Bex will be here shortly,” Kol chimes, taking out some lights and struggling to detangle them. You walk over to help him.
As Kol says, Elijah and Rebekah come with more decor than you can handle and even some presents. Elijah gives you the early gift of a record player, a sleek Audio-Technica he sets up in the corner. He puts on a Christmas record and lets Elvis Presley’s “Blue Christmas” sound fill the space. Rebekah decides your apartment should be rearranged and goes to work pushing the furniture into their new places, making Klaus help her. You join Kol in decorating the tree. This mainly includes you redoing what he’s done since he’s absolutely dreadful at it. He pretends like he doesn’t notice you do it.
“This one reminds me of you,” Kol says, holding up a bright red apple ornament. It’s lightly dusted in glitter.
“Why? Because I’m the apple of your eye?” You jest, earning a slight chuckle.
“In Jewish tradition, the apple symbolized strength and hope for prosperity,” Kol explains. “In Wicca, it’s a powerful tool for protection. Much like you.”
You don’t have anything to respond to that, as Kol places the apple in the perfect place. You don’t move to rearrange it, it’s already in its home. You blush under Kol’s gaze and go back to decorating.
Rebekah claps her hands to capture everyone’s attention.
“Family photo time!” She announces, brandishing a camera she must’ve found stashed in one of your drawers. Klaus groans, and she swats him. You all gather in front of the tree. Elijah holds the camera with Klaus behind him, Kol, you, and Rebekah. Rebekah wraps an arm around your middle and props her head on your shoulder as you lean into Kol to fit better in the frame. Kol puts an arm around your shoulders and rests his head against yours.
“Smile,” Elijah says, taking the photo. You all gather around the screen, and you can’t help but smile at how well it turned out.
“You have a future in photography,” you chuckle, nudging Elijah. He rolls his eyes.
“No, thank you.”
Klaus pours everyone some champagne (again, where he was finding your alcohol is a mystery). You see the star at your tree's top and struggle to fit it on. Grabbing a chair, you nervously climb atop it.
“Here, let me help,” Kol says, grabbing your waist for support as you get on your tip toes and fit on the star. He holds you as you step off the chair, finding yourself in his arms. “Can we go somewhere quiet?” He asks, a hint of a tremble in his voice.
You gesture towards the bathroom, a place that’s already too noisy because of your rocky heater. He walks ahead of you, and you close the door behind him. You watch as Kol takes in the checkered floors, blue wallpaper, and clawfoot bathtub.
“Darling, this place is horrendous,” Kol states, and you laugh.
“It works.”
“It’s terrible.”
“Not all of us are made of money,” you cross your arms, leaning against the counter.
“I have to get you a new place purely so I don’t have to look at this one,” Kol runs a hand through his hair, another hand on his hip. He looks ridiculous, and it makes you love him even more.
“What did you need the privacy for?” You ask.
“I have a gift for you,” Kol rifles through his pocket, pulling out a small red box. Your breath catches as he hands it to you. You open the box with trembling fingers to find a necklace inside. It’s simple, with a pendant of a moon eclipsing the sun. Your fingers trace with the charm with a delicacy reserved for beautiful things. “I saw it and thought of you.”
“I don’t know what to say…”
“Say you’ll let me take you on a date.”
Your head shoots up, and you look at Kol with wide eyes. For once, his expression isn’t one of a cocky vampire, but rather a nervous boy.
“What?”
“I figured it out,” Kol starts, stepping closer to you and cornering you by the door. “Why your heart beat so fast around me…why Rebekah is always asking me to do things with you…why you look at me when you think I don’t notice.” Kol looks down at you, forcing you to look up to meet his gaze. “You like me.”
“I—“
“It’s alright, I like you too. A lot. More than anyone in the past centuries,” Kol whispers. You wonder if maybe that wish you threw in the fire possesses real magic as you see your dreams coming true.
“Okay.”
“Okay?”
“You can take me on a date,” you answer, feeling your breath shaky as Kol steps closer.
“Can I call you my girlfriend?” He trails his fingers across your jaw, chin, and lips. Your body is on fire.
“You can call me your girlfriend,” you whimper as his nose brushes yours.
“Can I kiss you?” He lets his breath fan your face, and you can barely let out an affirmative before you grab him by the collar and drag his lips to yours. One of his hands boxes your head against the wall as the other holds your hip, pulling you closer. Your hands tangle in his hair, and you hear him let out a small groan at the action. You let him take control because you’re barely holding on with the way he kisses and touches you. You’re afraid you might break apart if he lets go, and you can barely hold in your gasp as his fingers brush under your shirt.
You would let him take you right there, and then if not for Rebekah knocking on the door.
“Stop snogging and finish the tree!” She yells, earning a growl from Kol as you hear her walk away cackling. He turns back to you, pressing a kiss to the corner of your lips as he looks at you with eyes the color of the night sky.
“How does 8pm tomorrow sound?”
“Sounds like a date.”

Summary: Studying anatomy is hard…luckily Klaus's extensive knowldege makes for an enticing study method
· · ─────────── ·· ────────── · ·
The anatomy textbook lay open on the bed, pages covered in Y/N's frustrated notes. She'd been at this for three hours trying to memorize the placement of organs and the names of bones and even the way everything connected in the human body. Keywords: Trying.
"I give up," she groaned, flopping backward onto the pillows. "The radius and the ulna are the same thing. Bones are stupid. Who needs this many bones?"
Klaus looked up from his easel where he'd been working on a landscape, a smirk playing at his lips. "You do realize you're saying this to someone who's broken most of those bones in other people, love. I could probably draw you a detailed anatomical chart from memory."
Y/N sat up, eyeing him suspiciously. "Are you seriously telling me that your extensive knowledge of torture has made you an anatomy expert?"
"A millennium of creative violence does provide certain educational benefits." He set down his brush, wiping his hands on a rag as he crossed to the bed. "What specifically is giving you trouble?"
She gestured helplessly at the textbook. "All of it? The bones in the arm. Where the liver actually sits. How the ribcage protects things. It's all just...words on a page. I can't visualize it."
Klaus picked up the textbook, scanning the pages. Then he set it aside and reached for her hand. "Then let's make it more interesting, shall we?" His voice dropped lower, taking on that dangerous edge that always made her pulse quicken. "Close your eyes."
"Klaus..."
"Trust me, sweetheart. This is educational."
She closed her eyes, feeling the bed shift as he moved behind her. His fingers wrapped around her wrist, thumb pressing against her pulse point.
"The radial artery," he murmured, his breath warm against her ear. "Right here. Can you feel your heartbeat under my thumb?"
She could. Her heart was doing complicated things that had nothing to do with anatomy and everything to do with his proximity. His fingers traced up her forearm, pressing gently.
"The radius bone runs here, along the thumb side of your forearm. And just beside it..." His other hand traced a parallel line. "The ulna. Two bones working together to let you rotate your wrist. Like this."
He demonstrated by turning her hand palm-up, then palm-down. “Now you'll remember," he said, voice thick with amusement. "Because you'll think of this every time you look at that textbook."
"That's cheating," Y/N breathed.
"It’s effective teaching." His hands slid higher, fingers trailing along the inside of her elbow. "The brachial artery branches here. Major blood vessel. Very dangerous to sever. I've seen men bleed out in minutes from a wound right here."
"You're supposed to be helping me study, not giving me nightmares."
"I'm doing both." She could hear the grin in his voice. "Where's the humerus, love?"
"Upper arm bone. Runs from shoulder to elbow."
"Good girl." His hands moved to her shoulders, thumbs pressing into the joint. "And here's where it connects to the scapula. Feel that? The way it rotates in the socket?"
He guided her arm through a slow circle, and she was acutely aware that this was the least educational anatomy lesson in the history of education.
"Now," Klaus said, his hands settling on her ribcage, "tell me what organs the ribs protect."
"Heart and lungs," she managed, though thinking was becoming increasingly difficult with his palms warm against her sides.
"And where exactly is your heart, sweetheart?" His hand slid to rest over her left breast, palm flat against where her heart was hammering. "Right here. Between the fourth and fifth ribs, slightly left of center. I can feel it racing."
"That's because you're being distracting."
"Am I now?" His thumb traced the curve of her bottom rib. "The liver sits here, on your right side, just beneath the ribcage. Largest internal organ. Extremely vascular, which means—"
"It bleeds a lot if damaged. I know. I read that part."
"But now you'll remember it." His hands spanned her waist. "Because you'll remember this."
Y/N opened her eyes and turned her head to find him watching her with that intense focus that still made her stomach flip even after three years.
"This is the worst study method ever," she said.
"Is it working?"
She grabbed the textbook, flipping to a diagram of the skeletal system. "Radius is thumb-side forearm bone. Ulna is pinky-side. Humerus is upper arm. Scapula is shoulder blade. Heart between fourth and fifth ribs, left of center. Liver right side, beneath ribs."
Klaus's grin was absolutely wicked. "See? Effective. You're going to ace this exam." He pulled her into his lap, textbook and all. "Now, shall we discuss the skeletal structure of the hand? I have very strong opinions about metacarpals."
"Of course you do."
But she didn't pull away. And when he started explaining the twenty-seven bones in the human hand while tracing each one on her palm, she actually retained the information. Even if he was using a thousand years of creative violence to help her pass anatomy.
· · ─────────── ·· ────────── · ·
Klaus was sprawled across his bed the following evening, reading a first edition of Byron's poetry. One he'd acquired directly from the source back in 1816. That’s when Y/N burst through the door with her anatomy textbook and a determined expression.
"Take your shirt off."
He lowered the book slowly, one eyebrow arching in amusement as a slow smirk spread across his face. "Well, love, I appreciate the enthusiasm, but generally there's a bit more preamble. Perhaps some—"
"I need to study muscles," she interrupted, already pulling sticky notes and markers from her bag. "You have muscles. Take your shirt off."
The smirk faltered slightly. "You want me to...what, exactly?"
"Be my anatomical model." She was flipping through the textbook, completely focused. "Yesterday you helped with bones and organs. Today I need to map muscle groups. The trapezius, deltoids, pectoralis major, all of it. So. Shirt. Off."
Klaus set the book aside, genuinely caught off guard for possibly the first time in decades.
"You're serious."
"Dead serious. I have an exam in three days and I still can't tell the difference between the flexor carpi radialis and the flexor carpi ulnaris."
"Those are in the forearm, love."
"I KNOW." She looked up at him with those eyes that had been wrecking his composure for three years. "Which is why I need a three-dimensional reference. Please?"
He couldn't quite suppress his grin as he sat up and pulled his henley over his head in one smooth motion. "You know, most people would just use diagrams."
"Most people don't have a thousand-year-old vampire boyfriend with perfect muscle definition." She stepped closer, textbook in one hand, sticky notes in the other. "Now hold still."
For the next twenty minutes, Klaus discovered what it was like to be treated as a living anatomy chart. Y/N circled him with scientific precision, comparing his actual musculature to the diagrams in her book. She pressed her fingers against his shoulder, feeling the way the deltoid connected, her touch clinical but maddening.
Klaus's breath hitched. It was subtle, just the slightest catch, but enough that he had to close his eyes and concentrate on maintaining his composure. Legendary self-control, and here he was, undone by her fingertips tracing the contours of his shoulder.
She scribbled "DELTOID - raises arm laterally" on a pink sticky note and pressed it onto his skin, completely oblivious to the effect she was having.
Her fingers moved to his chest, mapping the pectoralis major with careful attention. Klaus kept his eyes firmly shut, jaw tight.
"You alright?" she asked absently, not looking up from her textbook.
"Perfectly fine, love." His voice came out rougher than intended. "Just...focusing."
Another sticky note landed on his chest. Her palm pressed flat against his sternum as she smoothed it down. His breathing definitely wasn't steady anymore.
She moved to his back, and he felt her fingers trace the line of his trapezius from neck to shoulder blade. The touch was exploratory and entirely innocent in intent. But it was driving him absolutely mad.
"This is absolutely ridiculous," he muttered, more to himself than to her.
"This is effective studying. You said so yourself yesterday."
"Yes, but yesterday I was the one doing the teaching. This is different."
"How so?"
"Because yesterday I got to touch you. Today I'm supposed to sit here like a statue while you—" He broke off as her fingers found the tricep. "Bloody hell."
She patted his shoulder absently, already moving on to label different muscle groups. By the time she'd covered his arms, shoulders, chest, and back with sticky notes, Klaus looked like he'd been attacked by an overeagerly organized student, and his self-control was hanging by a thread.
Then her eyes landed on his paint supplies.
"Oh, that's perfect."
"What's perfect? Y/N, what are you—"
She'd already grabbed his cadmium red and a fine brush. "The book shows the muscles in different colors to distinguish them. If I outline them on you, I can see exactly where they start and stop."
"Absolutely not."
"Klaus, please? It'll wash off."
"I'm a hybrid, not a canvas!"
But she was already uncapping the paint with a look that meant arguing was pointless. He sighed, resigned to his fate. "You're lucky I love you."
"I know." She dipped the brush in red paint. "Now flex your arm."
Klaus sighed, obeying her commands snd she just...stopped. Stared. Her eyes fixed on the way his bicep curved under the skin, the definition of muscle that came from a millennium of fighting.
Klaus's eyes opened. The corner of his mouth twitched. "See something you like, sweetheart?"
She blinked, cheeks flushing. "I'm studying."
"Studying requires looking at the textbook occasionally." His smirk widened. "You've been staring at my arm for fifteen seconds which I would know because I counted."
"I was comparing it to the diagram."
"The diagram is on the table behind you, my love"
Her blush deepened. "Shut up."
"Make me." His voice dropped lower, teasing. "Or are you too busy admiring the brachialis? Perhaps the biceps brachii? I can flex again if you need a longer look." He flexed again, deliberately slow. "What happened to clinical detachment, love? All that scientific focus?"
"I hate you," she muttered, but she was fighting a smile as she finally pressed the brush to his skin.
She traced the bicep, her tongue caught between her teeth in concentration. The paint was cool against his skin, her touch feather-light as she followed the muscle's contour from shoulder to elbow. Klaus watched her work, and despite the torment of sitting still while she touched him so innocently, there was something quietly perfect about this moment. The little furrow between her brows and even the way she muttered anatomical terms under her breath.
She switched to blue for the triceps, yellow for the deltoid, and green for the pectoralis major. "There," she finally announced, stepping back to admire her work. "Perfect. Now I can actually see how everything connects."
Klaus looked down at himself covered in paint outlines and sticky notes, looking like the world's most ridiculous anatomy lesson.
"I look like a child's art project."
"You look educational." She was already taking photos with her phone from different angles. "This is going to help so much."
"Thrilled to be of service," he said dryly.
She laughed, finally looking up from her phone to really look at him. "Thank you. I know this is weird."
"Weird doesn't begin to cover it, love." He plucked a sticky note off his chest. "But if it helps you pass your exam, I suppose I can endure the indignity."
"My hero," she teased.
"Speaking of which." He stood, paint-covered and sticky-note-decorated, and closed the distance between them. "Since you've quite literally decorated me, I think it's only fair you help clean it off."
"I was going to let you shower—"
In one smooth motion, he had her lifted over his shoulder. "Klaus!"
"You put it there, sweetheart. You're helping wash it off." He was already heading toward his bathroom, her protests dissolving into laughter. "Consider it additional anatomy study. I'll even quiz you on muscle function while we're at it."
"That's not how studying works!"
"It is now."
The shower turned on, steam immediately beginning to fog the glass. Klaus set her down just long enough to start pulling sticky notes off himself, dropping them in a colorful pile on the bathroom counter.
"This is going to take forever," Y/N protested, but she was already pulling her sweater over her head. "Some of those paint lines are really detailed."
"Then I suppose we'll be here a while." He stepped under the spray, colored water already running down his chest as the paint began to dissolve. He held out his hand. "Coming, love?"
She took it, stepping into the shower with him, warm water cascading over them both. "You're going to quiz me, aren't you."
"Absolutely." His hands were already working shampoo through her hair, fingers massaging her scalp. "What's the largest muscle in the human body?"
"Gluteus maximus."
"Good girl." His hands slid down her back deliberately, finding exactly that muscle and squeezing with intent.
She gasped against him. "Klaus—"
"What? I'm being educational." But his smirk was absolutely wicked. "And what does the sartorius do?"
She tried to focus through the distraction of his hands still kneading her backside. "Flexes the hip and knee. It's the longest muscle in the body."
"Excellent." He pressed a kiss to her temple, then without warning, lifted her effortlessly against the shower wall. Her legs wrapped around his waist instinctively as the water streamed over both of them.
"What muscle did I just use to lift you?" he asked, voice dropping lower. Her brain scrambled to function while pressed against tile, held up by nothing but his strength.
"The—the deltoids helped. Biceps. Core muscles for stabilization."
"Very good, sweetheart." One hand slid up her thigh, squeezing the muscle there. "And what muscle is this?"
"Quadriceps," she breathed.
His hand moved higher, fingers tracing, caressing. "And this?"
"Adductors. Inner thigh."
"Mmm. You're doing so well." His lips found her neck, teeth grazing. "What about here?" His hand splayed across her ribcage.
"External obliques."
"Perfect." The word rumbled against her throat. "See how much better you remember when there's proper motivation?"
"This is—" She lost her train of thought entirely when his thumb traced circles against her hip. "This is not proper study technique."
"Isn't it? You're answering every question correctly." He shifted his hold, demonstrating his point. "What muscles am I using now to keep you exactly where I want you?"
She was trembling, and not from the cooling water.
"Deltoids, biceps, pectorals for...for holding. Core strength. Gluteus maximus for hip extension and—oh god—"
"Keep going, love. You're doing brilliantly."
"I can't think when you're—"
"When I'm what?" Pure innocence in his tone, completely contradicted by the way his hands were mapping her body. "I'm simply providing hands-on education. You said you needed a three-dimensional reference."
“I did?”
“Mhm. And you're going to ace this exam,” he finally lowered her back to her feet, though his hands remained at her waist. "Because every time you look at those diagrams, you're going to remember this. Aren't you?"
Her legs were unsteady, her heart was racing, and yes, she was absolutely going to remember every single muscle group now. "You're very pleased with yourself."
"Extremely." He tucked wet hair behind her ear. "Now, let's actually wash this paint off before the water runs cold. And I expect you to identify every muscle I use while doing so."
"You're going to make me work for this, aren't you?"
"Always, sweetheart." His grin was devastating. They stayed in the shower until every trace of color had washed away, Klaus continuing his relentless anatomical quiz while she scrubbed paint from his skin, both of them laughing when she got an answer wrong and he found creative ways to help her remember the correct one.
By the time they finally emerged, wrapped in towels with the bathroom thick with steam, Y/N had successfully memorized twelve major muscle groups and several creative applications thereof. And Klaus had a pile of sticky notes on his counter that he absolutely was not throwing away, along with the private satisfaction of knowing his girlfriend would never look at an anatomy textbook the same way again.
· · ─────────── ·· ────────── · ·
Klaus drove into her, his hands gripping her hips as she lay beneath him. But something felt off. Her responses were all there. The usual soft gasps and the way her body arched but her focus wasn't. Her hands weren't clutching at him desperately as they usually did; instead, they were...exploring. They were focused and dare he say too focused as they traced patterns across his shoulders and down his spine.
He slowed his movements, watching her face. Her eyes were slightly unfocused, her brow furrowed in concentration that had nothing to do with pleasure.
"Are you..." he began, disbelief coloring his tone, "Are you studying my musculature while I'm fucking you?"
Y/N's eyes snapped to his, a guilty flush spreading across her cheeks. "What? No! I'm—" she broke off as his expression darkened. "Maybe a little?"
Klaus stilled completely, still buried inside her, his jaw tightening. "Let me understand this correctly," he said, his accent thickening dangerously. "I have you naked beneath me, my cock inside you, and you're using this opportunity to mentally catalog my trapezius?"
She bit her lip, fighting a smile despite the tension. "It's just...they're right there," she explained weakly as he drops his head into the crook of his neck "And they're so well-defined when you're holding yourself up like this. I can see exactly where the latissimus dorsi connects to—"
"Oh my god." Klaus lifted his head to stare at her in utter disbelief. "I'm literally inside you and you're thinking about anatomy."
"It's your fault!" She tried to defend herself, fighting the smile tugging at her lips. "You made me use you as a study model and now I can't stop thinking about it!"
"That was supposed to help you pass your exam, not ruin our sex life!"
"It's not ruining—"
Klaus cut her off with a growl, pulling out of her entirely and flipping her onto her stomach in one fluid movement. Before she could protest, he'd pinned her wrists above her head with one hand. "If you insist on treating me like an anatomy lesson," he murmured against her ear, his free hand sliding beneath her to lift her hips, "then I'll make certain it's one you won't forget."
He entered her again, the new angle drawing a genuine gasp from her lips. "Now," he continued, his voice conversational as he established a punishing rhythm, "since you're so interested in muscle function, let's discuss what's happening right now."
His hand released her wrists to slide down her back, following the curve of her spine. "The erector spinae," he informed her, fingers tracing the muscles along either side of her vertebrae, "contracts to arch your back just like this."
His hand moved to grip her hip, fingers digging into the flesh there. "The gluteus medius," he continued, punctuating the words with a deep thrust that made her cry out, "stabilizes your pelvis while I'm taking you."
"Klaus," she moaned, all thoughts of studying forgotten as her fingers clutched at the sheets.
"No, no," he chided, reaching around to cup her breast, thumb circling her nipple. "Pay attention, love. This is educational. The pectoralis major," he squeezed gently, "so sensitive to touch."
His other hand slid between her legs, finding her center with ease. "And here," he murmured, circling the bundle of nerves with his fingers as he continued to move within her, "is where all those nerve endings converge. Fascinating bit of anatomy, wouldn't you agree?"
Y/N could only respond with incoherent sounds of pleasure, her body trembling beneath his expert touch.
"I asked you a question," he prompted, slowing his movements until she whimpered in protest.
"Yes," she gasped out. "Fascinating. Please, Klaus—"
"Please what?" His voice was silk wrapped around steel. "Continue the anatomy lesson?"
"No!" she cried out. "Just...please."
He leaned down, his chest pressed against her back, lips at her ear. "I want to hear you say it," he demanded softly. "Tell me where your attention is now."
"On you," she breathed. "You. I swear."
He smiled against her skin, satisfaction evident in the curve of his lips. "Good girl," he praised, resuming his earlier pace. "Now, shall I demonstrate what happens when these muscles contract all at once?"
His fingers moved faster against her center, his thrusts becoming more intense as he drove her toward the edge.
"Klaus!" she cried out, her body tightening around him as release crashed over her.
He followed her moments later, his own release punctuated by a low groan against her neck. They collapsed together, a tangle of limbs and ragged breathing. After several moments, Klaus rolled onto his side, pulling her against his chest. His fingers traced lazy patterns on her arm as their breathing returned to normal.
"So," he said finally, amusement coloring his tone, "did that help with your studies?"
Y/N turned in his arms to face him, her expression sheepish but satisfied. "Definitely," she admitted. "Though I'm not sure I could explain any of it on an exam."
"Perhaps not," he agreed, tucking a strand of hair behind her ear. "But I guarantee you'll never look at a muscle diagram the same way again."
She laughed, burying her face against his chest. "You're never going to let me live this down, are you?"
Klaus shook his head, a rare genuine smile softening his features. "Next time you need to study," he suggested, pulling her closer, "perhaps just ask me to pose for you properly. Less distracting for both of us."
"Where's the fun in that?" she countered, but he was already pulling her on top of him, all thoughts of anatomy lesson forgotten as her lips found his once more.
