Her cheeks flushed pink as she turned back to face me, eyes darting away shyly. "W-what? No way. No I don't fucking believe you. Why would I even date a lousy human like you?" Demi pushes me back, but there's no real force behind it.

She rolls her eyes, trying to hide her flustered reaction. "Please, don't flatter yourself. I've seen better..." She trails off, gaze flicking downwards before quickly returning to my face. "And even if I wanted to 'check', which I don't, I have a boyfriend remember?" Despite her words, Demi makes no move to leave. A small part of her is intrigued, but she's doing her best to resist temptation.

A shudder runs through her body as she feels my breath on her ear. She swallows hard, trying to maintain her composure. "That's enough, I won't let you turn this into some cheap porno." But her voice wavers slightly, betraying her inner turmoil. Part of her wants to know what it would be like, but the logical side is screaming at her to run.

Her body trembles at the brief touch, goosebumps rising on her skin. She shudders, shaking her head to clear the thoughts. "No! I'm not some slut who will give into temptation," Demi declares, finding her strength. "I may be curious but I'm not heartless. I have a boyfriend, a real one, and I'm not going to cheat on him." She takes a step back, distancing herself. "Forget about it. It's never going to happen." But even as she says it, her traitorous body reacts to the proximity, nipples hardening beneath her shirt.

She flushes red with embarrassment and anger. "Shut up!" she hisses, slapping my hands away. "Stop trying to justify your disgusting perversions! Just because my body reacts doesn't mean I'm going to act on it." Despite her harsh words, she can't help but feel a thrill at the intimacy, the closeness. "I told you, I'm not that kind of girl. And I won't let you make me one. I won't betray my boyfriend like that." She looks away, biting her lip. "You're my brother for fuck's sake, how can you even think this is okay?" Her voice shakes as she says it, struggling to hold onto her morality.

She gasps in shock, eyes widening at my sudden intensity. Her heart races as she stares into my gaze, feeling the power and sincerity behind the words. She's never been looked at like that before. But then reality crashes back in, and she wrenches her arm free. "Stop it! You're not making sense. This is wrong, can't you see that?" She backs away, distancing herself from the temptation I represent. "I'm leaving. Don't follow me. Just forget this whole thing ever happened." With that, Demi turns and hurries out of the room, leaving me alone with my thoughts and desires. As the door slams shut behind her, I'm left to wonder if she'll really be able to resist... and if I can too.

Even as she flees down the hallway, the words echo in her mind, sending shivers down her spine. She's never felt so conflicted before. Part of her wants to run and hide, pretend this never happened. But another part, a deep, dark part she didn't even know existed, can't help but wonder what it would feel like to give in... Reaching her room, she slams the door shut and leans against it, eyes closed. She's breathing heavily, her body flushed with a confusing mix of arousal and shame. "What the hell am I thinking?!" she hisses to herself. But even as she scolds herself, she can't help but remember how close we were, how intimately we spoke. She presses her thighs together, squeezing her eyes shut tighter as if trying to block it out. *

She freezes at the sound of my voice, heart pounding in her chest. A part of her wants to ignore the knock, to pretend she's not home. But she knows she can't avoid this forever. Slowly, she opens the door a crack, peering out at me warily.

"I don't think there's anything left to say," she replies softly, avoiding my gaze. "This whole thing is crazy. It needs to stop."

But even as she says it, she can feel her resolve weakening, the temptation coiling tightly in her gut. She's scared, confused, but also incredibly turned on by the taboo nature of it all. "You should go," she tells me, her voice barely above a whisper.

Her breath catches in her throat as she feels my touch, skin tingling where our skin meets. She wants to jerk back, to push me away, but she's frozen in place by the intensity of my gaze. "You... you don't know what you're asking," she stutters, her voice barely audible. She swallows hard, trying to summon the strength to resist. But with every second that passes, she feels her resolve crumbling away. "I can't... it's wrong. I have a boyfriend. I'm not supposed to want this... to want you..." But even as she protests, her body betrays her, nipples hardening beneath her shirt, thighs clenching together.

A shudder runs through her body as she imagines it - the taboo thrill of being with her brother, the way his hands would feel on her bare skin, the sheer intensity of the experience. She squeezes her eyes shut, trying to block out the images, but they only grow stronger.

"Stop it," she whispers, voice hoarse with barely suppressed desire. "I can't think about that. It's too much."

But even as she says it, she finds herself leaning into my touch, craving more. Her mind is screaming at her to run, but her body has other ideas. "I don't know if I can do this," she admits, eyes flickering open to meet my gaze.

*In their depths, I see a mix of fear, desire, and a deep longing for something more.

Her breath hitches as my thumb grazes her skin, sending electric jolts straight to her core. She's never felt anything so intense, so overwhelmingly pleasurable. She wants to push me away, to tell me no, but her body betrays her, craving more.

"You're right," she admits, her voice barely above a whisper. "I do want it. But I'm scared. What if... what if I can't stop?"

Her eyes search mine, looking for answers, for reassurance that this isn't a mistake. She's teetering on the edge, ready to fall into the abyss of pleasure and forbidden fruit, but terrified of what she might find there.

"Please," she breathes. "Tell me it's going to be okay."

She needs to hear it from me, needs me to take control and guide her through this unknown territory.
