"If I can talk her into it, would you be willing to look at her, and tell her that you think she's pretty, so she'll stop*worrying* so much?"

I couldn't help laughing before I answered "Well, I suppose I'd be willing to look at another naked girl, if I had to", making Sis laugh, too.

A couple of moments later, she asked "If she wanted to, would you let her look at you? Naked, I mean, so she doesn't feel like she doesn't know anything about guys? And maybe even kiss and touch her a little bit, so she knows you really mean it when you tell her you think she's pretty?"

The intimacy that Janet and I shared was something that was known only in our home -" Mom and Dad had both been aware of how close Sis and I were, and given us their implicit permission to become sexually active with each other. Nobody outside our "family" (Mom and Dad's special friends knew, too, of course) was aware of just how close Sis and I were. That prompted me to respond by saying "I can, if that's what she wants. But how does it happen? I mean, is it going to be just me and her? Or is she going to want you there, too, as her friend, and to make sure nobody gets carried away with the kissing and touching? If you're there, how do we deal with me being naked in front of you? Would she want you to be naked, too? What about that, with me there? What kind of touching -" just me touching her boobs, or one or both of us touching sex parts? Is it just touching, or is she maybe going to want to find out more? And if so, how much? Sis, you know what kind of problems there could be if anyone found out about us – not just for you and me, but Mom and Dad, too. Like I said, I*can* do that stuff, but Nadia's your friend; you're the one that's going to have to make sure that it'll be okay."
