Go into the kitchen

You decide to not be a perv and join Leila in the kitchen.

She turns around and asks you "You don't want to see my sister naked?"
You say that you don't want to embarrass Kate.
"Hahaha! She won't be" Leila replies, "I definitely wouldn't be!"
You look at her a bit confused and she says "No, I would be flattered if you would sneak a peak at me" while she pulls up the side of her black dress with her index finger. You can just see the underside of her butt and can tell she is not wearing any panties.

You start to blush.
"You don't like it?" she says.
"Yes I do, I just wasn't expecting this."
"Expecting what..?" she teasingly replies.
You can feel that your dick is slowly getting harder...
