Oh we have talked about it. It's something we both have been wanting to do sexually. Trying new things her and I. Looking for no attachments, strings attached type of night with another lady. We've even role played like another woman was there, talked about what we'd do and such.
Sounds like good advice. Especially if you can subtley steer her in the direction of one you already like, assuming of course that part of your 3some will involve you doing her
