Klaus's lips curled into a smirk as he observed Katherine's struggling form beneath him, his eyes alight with a malevolent spark as he gazed into her defiant eyes. He understood that mere threats no longer held sway over her; she recognized his current need for her presence and that he wouldn't kill her. However, he contemplated a different approach, one that would stir a deeper sense of fear within her. He could use his compulsion to make her do... whatever he wished her to do. Whatever would make her feel the most ashamed, the most humiliated and disgusted. That would be the true test of her mettle.

He slowly let go of her heart and withdrew his hand from her chest, his fingers now stained with her blood. He watched as her chest began to mend itself, the torn flesh knitting back together, the jagged wounds closing seamlessly as if they had never been there. The metallic scent now lingered in the air as he leaned back slightly, his expression tinged with a hint of satisfaction as he glanced down at her where she lay sprawled on the cold floor beneath him, battered and breathless. Her chest rose and fell with slow breaths, her body trembling slightly, although Klaus could tell she was trying her very best to hide it. Despite the defiance in her eyes, there was an underlying vulnerability that he couldn't ignore. He would break her eventually.

Instead of discarding the crimson remnants of blood and flesh on his fingers, Klaus began tracing a slow, deliberate path up her neck, leaving a dark crimson trail against her tan skin. As his fingertips grazed her cheek, he felt a subtle tremor run through her. He studied her for a moment, his gaze lingering on the delicate curve of her jawline, the graceful arch of her neck, and the slow heaving of her chest. He leaned in just a bit closer to her face to speak, his breath brushing softly over her skin.

"You've been a bad girl, Katerina," he began slowly, his tone dripping with mockery. "And what happens to bad girls who step out of line?"

Katherine scrunched her nose at that. She recoiled from his touch, a look of revulsion crossing her features. "Whatever punishment you're gonna give me, get it over with. But spare me the nauseating pet names, I feel like throwing up just hearing those words coming out of your mouth," she retorted, her voice tinged with contempt.

"Oh, do you now? Do you truly feel so disgusted?" he murmured, dropping his voice to a low, almost seductive tone. He was enjoying this. "Then why is your heart beating so fast? I can hear its frantic rhythm, almost even without activating my heightened senses."

He could have sworn he saw a flush of red flicker across her cheeks then. "Well, let's see," she began, her tone laced with hostility. "You were only just inches apart from ripping it out earlier. That might affect it just a little, don't you think?" Her words came out in a sharp retort, as if she tried her best to deny the rising tension between them as they laid on that floor, uncomfortably, painfully close. She tried again to pull away from him, but Klaus's grip only tightened, holding her in place as he compelled her to stay put. Frozen beneath him, she was rendered immobile, unable to move or resist. Even as he released her wrists, she was completely at his mercy.

Klaus's lips curled into a predatory smirk as he observed her reaction. "Hmm? Are you suggesting you're not enjoying me touching you right now?" he taunted, his voice laced with amusement. His fingers continued their leisurely descent down her arm, tracing a tantalizing path that left a trail of goosebumps in their wake.

She vigorously shook her head in protest. "Hell no," she spat out, her tone dripping with disdain.

"Well what are you gonna do to stop me?" he continued to taunt her, a sardonic grin playing on his lips. "What's your grand plan? How will you thwart me?" His voice dripped with sarcasm as he awaited her response, relishing in the opportunity to belittle her. "You're powerless, aren't you?" he remarked softly, as he trailed his fingers gently along her cheek, knowing she couldn't slap his hand away. He enjoyed the shudder that coursed through her body as he did. Whether she reacted out of fear or something more intriguing, it mattered little to him; the effect was equally satisfying.

"Do you know how long I've waited to touch you again, Katerina? My dear, I've missed you, you know." He said that last sentence with such sarcasm, knowing she would hate those words of endearment.

"Screw you," she muttered, unable to do anything other than simply lay there and glare at him.

"Oh, you don't like it now? But you were so shamelessly flirting earlier," he reminded her, his tone dripping with mockery. Katherine only thrived when she was in control, and he knew that. Which was precisely why he was doing this to her now.

His fingers eventually trailed down to her mouth, his touch strangely gentle as he brushed his thumb over her lips, tracing the contours slowly. With deliberate slowness, he eased his thumb into her mouth, forcing her to taste her own blood. Katherine's tongue felt warm and wet around his finger, her gaze locked with his in defiance and pure anger. The way she was glaring up at him while he forced her to taste her own blood made a flicker of hidden desire surge within him, but he quickly pushed the thought away.

"I hate you," she muttered, her voice laden with frustration, her body still trapped beneath his.

Klaus's smirk widened as he leaned in closer, his eyes locking onto hers as his pupils dilated. "Do you really?" he taunted, his voice laced with a hint of amusement as he compelled her to reveal her true feelings.

"I do," she retorted, her voice venomous. She didn't know why he would use compulsion on her to get an answer, as if she wouldn't willingly admit her hatred for him a hundred times over until it was drilled into his head.

"Why do you hate me?" he continued.

"Because you killed my family."

"Is that the only reason?"

Katherine's resolve wavered for a moment, her anger momentarily giving way to a surge of conflicting emotions. She turned her gaze away from him, compulsion making her shake her head reluctantly. "I was hurt..." she mumbled, before even registering what the compulsion was making her say. "I was hurt because I felt betrayed, because I-" She cut herself off abruptly, her words catching in her throat.

But the compulsion proved relentless, and words soon spilled from her lips before she could stop it.

"Because I had truly loved you, and you betrayed my trust. I hate you because you murdered my family and took everything from me, yet a part of me still wanted you deep down. I hate you for corrupting me."

She couldn't even control what she was saying as he compelled out a truth in her she hadn't even been aware of herself. It wasn't true. Her heart pounded with a mixture of shock and embarrassment, however, Klaus didn't seem surprised. His smirk only widened in response, his eyes alight with amusement.

"Glad to know you still fancy me," he remarked casually, the smugness evident in his tone.

"I don't", she snapped.

"Oh you don't?" he prodded as he compelled her again. "Now be honest, sweetheart. You secretly want this, don't you? You like it when I'm pinning you down like this."

Katherine's breath caught in her throat, her mind racing as she struggled against the compulsion, her lips parting involuntarily. "I.."

Her voice trailed off as she met Klaus's intense gaze. It was clear he was looking to break her. There was pure enjoyment in his eyes at her discomfort, he was relishing in the control he had over her.

"Yes..." she finally admitted, her voice barely above a whisper, her cheeks flushing with embarrassment.

"What more do you want?"

Klaus's question hung in the air, loaded with implications. He wasn't genuinely asking her because he was interested, he was just looking to humiliate her. She knew what he wanted to hear, what he was forcing her to admit, and the mere thought of uttering those words filled her with a sickening feeling.

But his eyes bore into hers with such an intensity that made Katherine's breath catch in her throat. She could feel the weight of his gaze, heavy and oppressive, as if he were peeling back the layers of her soul with nothing more than a look. Every instinct screamed at her to resist, to fight against the compulsion that threatened to betray her deepest desires. But try as she might, it was magic, and she couldn't resist it.

"I want you to fuck me."

The words slipped out of Katherine before she could even register what she was saying. As the admission hung heavy in the air, she felt a surge of shame and self-loathing wash over her. She couldn't believe she had just said that, especially to Klaus of all people. She could hardly bear to look at him, knowing that he had stripped away her last shred of dignity with nothing more than a few words.

She had never allowed herself to acknowledge the twisted desire that lurked within her, the longing for the very man who had torn her life apart. He had manipulated her feelings, twisted her reality, and for the past five centuries he had wielded power over her mind, weaving himself into the very fabric of her existence. And now, with his very own compulsion, he had forced her to confront it head-on. She felt utterly exposed, stripped to the very bone.

Klaus watched her with a mixture of amusement and triumph, his eyes gleaming with satisfaction at having unraveled her deepest desires. "How interesting," he mused, his voice dripping with smug superiority. "Well, isn't this a revelation? You surprise me, Katerina. After all this time, you still harbor such conflicting desires."

She wanted to protest, to scream that he was wrong. That it was a coaxed confession. But deep down, she knew he had unveiled a truth she had long denied. Her own body betrayed her, confirming the dark desires she had buried deep within.

"I killed your family, tormented you for five centuries, yet even after all these years, you still crave me," Klaus mused, savoring her discomfort.

Katherine seethed with resentment, and she wanted nothing more than to peel the skin right off his smug face, skin his pretty flesh and burn it and throw the ashes at sea. She wasn't sure if there existed a sweeter irony. He looked as if he was molded by God himself, with his golden hair and perfectly shaped face. When in reality, he was anything but. He was her own personal demon, sent from hell to torment her for eternity.

"I hate you," she repeated. It seemed to be the only thing she could think to say. The only truth she knew was real.

"And yet, you want me to fuck you," Klaus retorted, his tone dripping with arrogance. "If that's truly what you desire, I can give it to you."

Katherine shook her head vehemently, spitting out her words like venom. "Screw you. Go to hell," she spat, her voice trembling with anger and frustration.

Klaus only sighed in response, his smug expression still etched onto his features as he eventually released his grip on her. Rising smoothly to his feet in one fluid motion, he cast a final glance in her direction before striding purposefully towards the hallway of the apartment. Katherine finally felt like she could breathe for the first time in a long time, the tension that had gripped her chest slowly dissipating. She remained on the floor for a few more seconds, watching him walk away from her with a mix of relief and resentment.

Eventually, Katherine rose to her feet as well, straightening herself out as she observed Klaus adjust the lapels of his coat with a swift, almost dismissive gesture. His demeanor was as cool and collected as ever, as if he hadn't just been physically and mentally torturing her.

Before leaving, he delivered a brief departure, his voice echoing through the quiet apartment. "I'll be out for tonight. Business," he stated matter-of-factly, before turning to leave.

Katherine offered no response. She simply stood there and watched him as he opened the door and exited the apartment. Doing the exact thing she wasn't able to do herself. And once again she was left alone in that silent apartment.
