Star had just left the room, and Sue and I were looking at each. Finally, Sue spoke. "I'm sorry she left you with blue balls like that. I thought she was going to let you fuck her."
"It's OK. Honestly, skinny blondes aren't my type." Sue, who is dark haired and fleshy but by no means fat, blushed. "Were you going to watch us?"
"What?! You're my brother!" While we were mulling over this fact (although I am actually her half-brother), loud rock music started playing downstairs. Star wanted us to know she couldn't hear us.
"It sounds like she really expects us to do it," I said, "We may as well."
Sue seemed to ponder this. "Nah. We've had some fun but there's still a line I won't cross."
"At least you can help me with my blue balls."
"You just said you were OK... and I'm not touching it."
"At least give me a show, then." Sue sighed and slipped off her nightgown, leaving her in red panties with pubes sticking out the side. To give you a visual, she more or less looks like this lady:

I took my dick out and starting stroking it in front of her. . .
