Work Text:
The school library was quiet, save for the soft hum of whispers and the occasional shuffle of books. Stefan Salvatore walked down the stairs, each step heavy with the weight of his thoughts. He had been doing his best to avoid Elena ever since their breakup, but fate clearly had other plans. There she was—his ex-girlfriend—standing near the bookshelves, her face lit up with that infuriatingly perfect smile she used to reserve for him. Only now, she wasn’t smiling at him. She was smiling at Damon, his older brother.
It was the final straw. Something inside him snapped, a dark need clawing its way to the surface. If she could replace him so easily, why couldn’t he? But he wasn’t going to choose just anyone. Oh, no. He wanted someone who would make Elena jealous. Someone who could make her question her choices, her desires, her entire existence. The idea came to him suddenly, reckless and thrilling. He’d ask Katherine to the dance.
It wasn’t just any plan; it was a carefully calculated act of revenge. Katherine, Elena’s identical twin sister, was everything Elena wasn’t—bold, fearless, unapologetically herself. She was also the most popular and intimidating girl in school, a certified heartbreaker who could make anyone fall for her with just a glance. The idea of parading Katherine in front of Elena, of watching her face twist with jealousy, was too tempting to resist. But as Stefan scanned the library for Katherine, reality set in. What the hell was he thinking? Katherine wasn’t the kind of girl you casually asked to a dance. She was out of his league, completely untouchable.
He almost turned to leave, but then he spotted her near the library doors. She was leaning casually against the wall, scrolling on her phone, but even in such an ordinary moment, she radiated confidence. Her dark eyes met his, identical to Elena’s yet so different. Katherine looked at him like a predator sizing up prey.
“What was that?” she asked, her voice smooth and almost amused as she raised a perfectly arched brow. Stefan swallowed hard, suddenly feeling like an idiot.
“I—I wanted to ask you to the dance. If you’re interested, that is.” His voice cracked, betraying his nerves, and he internally cringed. Katherine tilted her head, a smirk tugging at her lips.
“Oh, really? What happened to Elena?”
He hesitated, then forced the words out. “We broke up.” For a moment, she said nothing, her expression unreadable. Then, her smile widened.
“I know.” Her words were low, almost a purr, and they sent a chill down his spine. “I’ll see you there, Stefan Salvatore,” she said, her voice dripping with promise as she turned and walked away, leaving him stunned.
He couldn’t believe it had worked.

Katherine was used to getting what she wanted. She was the girl everyone loved and feared, the queen bee who could have anyone she desired. At least, that’s what people thought.
What they didn’t know was that the one person she wanted most was the one she could never have: Stefan Salvatore.
She had a crush on him since high school. But he only had eyes for Elena, her goody-two-shoes twin sister who always seemed to get everything handed to her on a silver platter. Watching him dote on her sister, always so kind and attentive, had been torture. Katherine hated Elena for it—her perfect life, her perfect boyfriend, her perfect everything. And in college, not much had changed.
But now, they broke up and Stefan asked her to the dance. She played it cool, even as her heart raced. She accepted his invitation like it was no big deal, brushing off the fact that she already had a date lined up and more offers than she could count, because this wasn’t just anyone—it was Stefan. The moment she stepped out of the library, she was on cloud nine, already planning the perfect dress to make him forget all about Elena.
~▪︎~▪︎~▪︎~▪︎~▪︎~
The library had been transformed into a vibrant dance floor. Lights flickered across the room, and music thumped in every corner. Stefan stood awkwardly by the punch table, sipping cheap beer and checking the clock every few minutes.
Katherine still wasn’t there.
He’d texted her earlier, offering to pick her up, but she’d declined, saying she’d meet him there. He scanned the crowd, his stomach tightening when he spotted Elena dancing with Damon. The sight made his blood boil, and he turned away, forcing himself to focus on anything else. That’s when he ran into Tessa.
“Hey, Stefan,” she purred, her words slurring slightly. “You look like you could use some company.”
“I’m fine, Tessa,” he said politely, trying to edge past her. She grabbed his arm, leaning in closer. “Come on, let’s get out of here. Just you and me.” Stefan sighed, gently prying her hand off his sleeve. “I think you’ve had a little too much to drink,” he said, steering her back.
Once he’d made sure she was safely seated, he decided to escape outside, needing a moment to breathe, and that’s when he finally saw her.
Katherine.
She walked into the room like she owned it, wearing a sleek wine-colored dress that clung to her curves. Her dark curls framed her face, and her crimson lips curved into a smile when she saw him.
“I was starting to think you wouldn’t show," he said, trying for casual as he approached her, but his voice came out slightly breathless.
“I wouldn’t miss this for the world,” she replied, her confidence intoxicating.
As the night went on, they danced and talked, her confidence drawing him in like a moth to a flame. For the first time in days, Stefan stopped thinking about Elena. Katherine demanded his attention with her sharp wit and the way her body moved against his. He didn’t even have to pretend he was enjoying himself—he was completely captivated. After a while, though, the crowded room and loud music became too much.
“Will you excuse me for a moment?” Stefan asked, stepping back. Katherine frowned, her hand brushing against his cheek. “What’s wrong?”
“Nothing, I just need some air,” he said, but before he could leave, she grabbed his hand and pulled him along. “Good idea,” she said with a mischievous grin.
~▪︎~▪︎~▪︎~▪︎~▪︎~
They ended up in a quiet reading room, the noise of the dance fading into the background. He smiled at their still joined hands and slowly let go. "Thank you for agreeing to do this," he said softly, his green eyes meeting hers in the dim light.
She smirked and leaned in slowly, her lips meeting his. It started soft, almost hesitant, but quickly deepened. After letting out a surprised moan, Stefan tangled his hands in her hair, and she pressed herself closer, reveling in the heat between them.
Katherine unbuttoned his shirt, letting her hands roam over his chest. Then, she slowly unzipped her dress and let it fall to the ground, all while kissing Stefan passionately. Suddenly, he broke the kiss, panting heavily as he rested his forehead against hers.
"Wait. We can't do this. I've got something to tell you," he said, pulling back to see her frowning face. She didn’t say anything, just waited for him to finish. "I asked you to the dance with me because I wanted to get back at your sister and—"
"I know, Stefan," she whispered, looking him honestly in the eyes.
"And so it wouldn’t be fair to you if we did this because I—"
"Shhh," she interrupted, pressing her finger to his lips. "Ever the gentleman, aren’t you?" She smiled and gave him a chaste kiss before continuing. "You don’t have to treat me like I’m made of porcelain. I won’t break. I don’t expect you to love me, Stefan. I just want you to fuck me. To be with me tonight." She leaned closer, whispering her next words in his ear. "You can pretend I’m her, if you want."
And Stefan tried—he really did. But the whole evening, he failed. Katherine was nothing like Elena. And that was his problem. He liked Katherine. He liked that she was nothing like her sister. And that terrified him.
"Let me make you feel good," she murmured, pressing kisses to his chest and pausing to bite at his nipple. Stefan moaned, letting his head fall back. "I want you," she said, taking his hand and guiding it down her belly into her panties, where she really wanted him. She moaned as he touched her. "So much," she finished, letting him feel how wet she was. Their eyes locked, and suddenly, he pulled her against him, kissing her with intensity. She smiled into the kiss as she unbuckled his belt and removed his pants.
"Katherine," he groaned, finishing undressing her. She pushed him to sit on the bench behind them, straddling him and capturing his lips once more. When they couldn’t hold back any longer, she took his already hard cock and stroked it a few times. He groaned in warning not to tease him, though it sounded more like a desperate plea.
"Katherine," he said again, his voice raw. She smiled as she guided him to her entrance, slowly sinking down onto him. When he bottomed out, they both moaned in unison. He kissed her as she began to ride him and not exactly slow either.
The way her eyes shone with desire, the way she moved rhythmically, the sounds she made—it all drove him wild.
Katherine couldn’t believe her luck. The man she had always dreamed of was right here, making love to her. She was determined not to show him what a big deal it was, instead opting to say she only wanted to have fun with him. But with every thrust, she looked deep into his eyes, silently saying what she couldn’t voice out loud: that she loved him and that he was hers.
Only hers.
She would never make the same mistake her sister did—she’d never let him go. And Stefan? Well, he’d just have to get on board with that. For now, though, she expressed what she felt for him through the intensity of her kisses and the depth of her gaze.
Stefan groaned, thrusting into her, earning a broken cry of, "Stefan!" And so, he did it again and again. She kissed him desperately, trying to muffle her moans, but by now, Stefan knew exactly what to do to break her control.
Her orgasm hit suddenly, and she collapsed against his chest, biting his neck hard. He groaned, thrusting a few more times before his own release overtook him. For a while, the only sound in the room was their heavy breathing.
"Wow," she finally said, still breathless. "That was incredible." She smiled, and he kissed her, because yeah, that was damn incredible.
"Wow," he repeated, and they both laughed softly. He looked at her as if he was about to say something, but Katherine feared it would be the ‘You’re not Elena and this means nothing’ speech, so she beat him to it.
"We should head back," she said, getting off him. They both hissed as she pulled herself off.
"Uh, yeah," he stammered, suddenly unsure, as if he’d just realized what they’d done. He began searching for his clothes. After the awkward dress-up, neither of them knew what to say.
"If you’re done dancing with me to make Elena jealous, I think I’ll head home," Katherine said, smirking. "You’re quite large, and you sure know how to make a girl tired and sated."
He stared at her in disbelief, and she decided to leave. But before she could, Stefan found his voice. "Wait," he said firmly. She stopped but didn’t turn to face him. "Let me walk you," he added softly. She smiled and waited for him.
Outside, Stefan draped his jacket over her bare shoulders, noticing the hickeys just below her collarbone. Did he do that?
"Thank you for the invitation," she said. He nodded, still at a loss for words. "Goodbye, Stefan." She handed him back his jacket and pressed a soft kiss to his cheek before walking away. Or so she tried.
Stefan caught her hand, pulling her back to him and kissing her deeply. She moaned into the kiss as he pressed her against the cold wall, moving to her neck to leave more marks. After a while, he gave her one final kiss and stepped back.
"Goodnight, Katherine," he said, leaving her breathless.
~▪︎~▪︎~▪︎~▪︎~▪︎~
Katherine felt like she was in heaven. Not even Elena's complaints about Stefan could dampen her mood. She was lucky Katherine had covered up the hickeys on her neck. When she finally went to bed, she pulled out her phone, sent a text, and tossed it away again, her fingers brushing her lips where, just a few hours ago, his had been.
~▪︎~▪︎~▪︎~▪︎~▪︎~
When Stefan woke up, his first instinct was to check his phone, as if there was some kind of connection. He smiled when he read her text:
"Goodnight, Stefan."
He had walked away before she could reply, and Katherine wouldn’t be Katherine if she didn’t have the last word.
He couldn’t get her off his mind, and the whole day at school, he only thought of her. Then, suddenly, he saw someone walking toward him, fast and angry. He shook his head, realizing it was Elena who wasted no time confronting him.
“What are you doing with her?” Elena demanded, her voice sharp. Stefan raised an eyebrow.
“What do you care? You’re with Damon now.”
“That’s not the point!” she snapped. “She’s just using you, Stefan. She doesn’t care about you.” Elena hissed, but Stefan wasn’t listening.
Later that afternoon, he found Katherine in the hallway. She smirked at him, her eyes glinting mischievously.
“Hey, handsome.”
Without thinking, he followed her into a nearby storage room. When the door clicked shut behind him, he told himself he just wanted to talk. But the second Katherine turned to face him, he knew that wasn’t true.
By the time Katherine walked out of that room, her smirk firmly in place, Stefan following behind, his shirt wrinkled and his heart racing, two things were crystal clear:
1. He was over Elena.
2. He was completely, utterly screwed.
