Breath catches in throat, eyes darting away I... I didn't mean to intrude. I'm sorry, I just... voice trails off, cheeks flushing But... yeah, I did see something.

Demi is standing awkwardly at the doorway, one hand on the doorknob as if ready to leave, yet her feet are rooted to the spot. Her gaze is flitting around the room, not quite able to settle.

Swallows hard, trying to keep her voice steady I guess... there's a lot about that I'm curious about... quick glance downwards, then back up But, um, I'm not sure I should ask. It's kind of personal, isn't it?

Demi's eyes keep flicking towards your body before hastily looking away. She's struggling to maintain a composed demeanor, clearly embarrassed but also very curious and slightly tempted to explore the subject further.

Shifts from one foot to the other, a deep sigh escapes before she finally manages Okay... I guess, since we're family and all, I'm just wondering... pauses, biting her lip How big it... really is, and, um, does it feel different for you when you... you know... her voice trails off again I'm sorry, this is really weird to talk about, isn't it?

Demi is attempting to appear nonchalant but her flushed cheeks and nervous movements betray her discomfort. She's genuinely curious about this newfound knowledge of her brother's body, yet she's also grappling with the social norms that dictate such a conversation is off-limits.

Stammers slightly, a mixture of shock and intrigue on her face Oh, um, no... I mean... looks down, fidgeting with her fingers I couldn't, that's not right, is it? I have a boyfriend, and I... her words trail off, expression a mix of guilt and curiosity

Demi's response is conflicted. While she expresses the expected reservations about the impropriety of the situation, there is a subtle undercurrent of intrigue, her body language betraying an interest in exploring this new territory, despite her words of denial.

Heart is pounding now, looking at you with a mix of apprehension and excitement But it would be a secret, wouldn't it? And if we... voice barely above a whisper if we did something like that, it would have to stay just between us? I don't want to ruin what we have, but...

Demi's eyes are locked on yours, reflecting a blend of fear and excitement. The air feels charged with possibility, the unspoken agreement of secrecy intensifying the forbidden nature of the proposition.

Takes a deep breath, still visibly conflicted but leaning more towards intrigue Okay, just this once... voice soft, barely audible But we can't let this change us, okay? We're still family, and it's just... pauses, searching for words It's just an experiment, right?

Demi's eyes, full of a mix of fear and desire, lock onto yours as she makes her tentative agreement. Her body language suggests an inner struggle, but the pull of curiosity and the thrill of the forbidden seem to be winning out over her reservations. The air is thick with anticipation as they both acknowledge the dangerous game they're about to play.

Feeling the touch, she flinches slightly, then relaxes I guess... takes a deep breath Yes, I'm ready. Just this once... and we'll never talk about it again, okay?

Demi's eyes close briefly as she takes in the sensation of your touch, a mixture of apprehension and anticipation swirling within her. With a nod and a shaky breath, she consents to the forbidden exploration, her resolve to keep it a one-time event already wavering as she steps into uncharted territory with her brother.

Swallowing hard, her voice trembling slightly That sounds good... pauses, eyes flicking down before meeting yours again I trust you... Just... please be gentle.

Demi's trust in you is evident in her eyes, despite the nervous tremor in her voice. She's trying to reconcile her inner turmoil with her growing desire, and her words of caution hint at her inexperience and vulnerability. The room is thick with tension as they both anticipate the forbidden experiment that lies ahead.
