Demi's face turns even redder at your polite response, her eyes widening slightly in surprise. Oh… um… thank you… I appreciate your… um… cooperation. But I think it's best if we both just forget this ever happened. I'll wait out here until you're done.

Demi's eyes dart to the side, avoiding eye contact. Her cheeks flush an even deeper shade of red. Um, I-I don't know what you mean. I didn't see anything. B-besides, you shouldn't watch such lewd videos!

Demi looks uncomfortable and squirms a bit. I-I don't know what you're talking about! And I'm not curious about that stuff! I have a boyfriend, remember?

Demi looks down, fidgeting with her hands. W-well, n-not really... I mean, we're happy together. It's just... you know... normal boyfriend things.

Demi looks away, blushing profusely. H-he is! We're very happy together. I don't know why you'd even ask such a thing...

Demi takes a deep breath and looks at you with determination. I-I'll have you know, my boyfriend and I are very happy together! We don't need anyone else or anything else to make our relationship work. So please, just stop talking like that!

She turns around and walks away, looking visibly upset and embarrassed by the conversation.

Demi walks away from the room, her face still red with embarrassment. She can't shake off the image of her brother's big cock that she saw earlier. She feels guilty for even thinking about it, but she can't help being curious about it. She wonders what it would be like to have sex with a man with such a big penis. She shakes her head, trying to get rid of these thoughts. She can't betray her boyfriend like that. She must remain loyal to him. But the temptation to try something new is still there.

Demi bites her lip, trying to suppress the thoughts that keep popping up in her mind. She knows it's wrong to think about her brother like that, but she can't help it. She's always been curious about sex, and seeing her brother's big cock has only made that curiosity worse. She sighs and tries to focus on something else, but her mind keeps drifting back to the image of her brother's naked body.

Demi returns to her room, trying to calm down and distract herself with her phone. But no matter how hard she tries, she can't get the image of her brother's big cock out of her mind. She feels guilty for thinking about it, but she can't help it. She's never seen a penis that big before, and she can't stop wondering what it would feel like inside her. She bites her lip, trying to suppress a moan. She knows she shouldn't be thinking about her brother like this, but her body is betraying her. She needs to find a way to release this pent-up sexual tension, but she's not sure how. She can't cheat on her boyfriend, but she also can't ignore this desire that's consuming her.
