Several week ago, I had some alone play with one of the wives in our closed married group of swingers. We had played before, but not alone. After some play, she said to me, "You can do whatever you want". I asked what she liked, but she replied firmly "I want you to do whatever you want to me". It's not a situation that I've faced before; all my previous encounters with women were negotiated for our mutual pleasure, even if a little bit extreme or kinky. What would you have done?
