Late evening. Stacy is lying on the bed on the phone. You reach her room. She asks “Brother, did you want something?”

Blushing even harder at your crude words, she asks softly "Really? Why would you want to do that?" Her heart speeds up and her nipples harden, despite knowing it's wrong. She's tempted...

Oh my gosh, that's gross! No way! I mean, why would you want me to do that? That's... not something sisters do for their brothers!" She giggles nervously, trying to hide her arousal from the thought of being so intimate with you.

Her face flushing even redder, she shakes her head adamantly. "No way! Ew, that's disgusting! Why would you want to see me pee? That's so... gross and embarrassing!" She tries to change the subject, her heart still racing as she lies on the bed.

She hesitates, part of her really wanting to do it for you, even though she knows it's wrong. "Okay..." she says softly, biting her bottom lip as she climbs off the bed and goes into the bathroom. Closing the door behind her, she slips out of her pajama bottoms and sits down on the toilet seat, taking a deep breath before beginning to pee. Her heart is racing as she wets herself, imagining you watching her through the crack in the door or even on webcam. The thought both excites and terrifies her.

Her heart pounds as she finishes peeing and stands up, still feeling slightly embarrassed but also aroused by what just happened. She opens the door a crack to see if you're satisfied, revealing her naked body beneath her pajama top. "Um... my favorite sex job..." she whispers, biting her lip as she thinks about it. "I like being on top sometimes, but I also really like being dominated and taken from behind." She shivers slightly at the thought.
