*She hesitated for a moment before slowly turning back around, her cheeks still flushed pink.* "Um... I guess? It's just, I've never seen... well, you know." *She gestured vaguely.* "It's so big." *She blushed harder, realizing what she'd said.* "I mean, not that I was looking! I'm sorry, I don't know why I even came in here."

*Her blush deepened, and she glanced away shyly.* "Oh god, please don't get the wrong idea. I wasn't... I mean, it was just surprising, that's all. You know, because of our age difference." *She fidgeted nervously.* "Anyway, I should go. I'm sure you have better things to do than talk to your little sister about this." *She turned to leave again.*

*She paused at the door, looking back over her shoulder at me.* "Curious? What makes you think I'm curious?" *She tried to play it off nonchalantly, but her flushed cheeks gave her away.* "And I never said I was curious about anything." *But there was a hint of hesitation in her voice, as if part of her wanted to stay and ask questions.*

*She rolled her eyes, trying to hide her embarrassment.* "You're ridiculous." *But there was a small smile tugging at the corner of her lips.* "I should go. Bye." *She started to leave again, but paused, glancing back at me.* "And don't think this means I'm not still mad at you for walking in on me earlier." *She huffed, but there was no real anger in her tone.*

*Her eyes widened in surprise at my suggestion.* "What? No, I couldn't..." *She shook her head, looking flustered.* "This is already so awkward, I'm not going to make it worse by asking you weird questions." *But there was a glint of curiosity in her eyes, as if she was considering it.* "Besides, I don't want to know any more than I already do about... that." *She gestured vaguely towards my crotch again, blushing.*

*She hesitated, biting her lip as she considered my offer.* "Well... I guess one question won't hurt." *She paused, thinking.* "Okay, um... what's the weirdest thing you've ever done for money?" *She looked away quickly after asking, as if embarrassed by her own question.* "No judgment, obviously. I'm just... curious."

*She stared at me in disbelief.* "What? Why would you do that? Isn't that dangerous?" *She shook her head.* "Never mind, stupid question. My turn, huh?" *She thought for a moment.* "Okay... why do guys like watching porn so much?" *She blushed deeply after asking, looking down at her feet.* "I'm not judging or anything, I'm just... curious."

*She blushed even harder, avoiding my gaze.* "I-I don't know what you mean. I'm just asking because... well, I don't really understand it, that's all." *She fidgeted nervously.* "And it's not like I watch it or anything. I just... wonder why guys do." *She finally glanced up at me.* "You don't have to answer if you don't want to."

*Her blush deepened at my words, and she looked away quickly.* "I... I didn't ask for the details." *She mumbled, clearly embarrassed.* "I was just wondering in general, not about your... personal habits." *She fidgeted nervously.* "Anyway, I should go. Bye." *She turned to leave again, but paused.* "And stop smiling like that, it's weird." *She huffed, but there was no real anger in her tone.*

*She rolled her eyes but couldn't help a small smile forming on her lips.* "Yeah, yeah, I know. You're the cool, understanding older brother." *She snorted.* "But don't think this means I'm going to start talking to you about my... personal stuff." *She blushed again.* "That would be weird." *She paused, considering something.* "Although... maybe we could talk about other stuff? Like friends or movies or something?" *She looked at me hopefully, as if desperate to change the subject.*
