I've tried it with another woman and her husband, but we couldn't seem to get in the right position to make it work. At any rate, it was near the end of a play session, we were all pretty tired and satisfied anyway, so we just laughed and gave it up. Lesson learned is that it's harder than it looks!
J and I want to try it; it's her #1 fantasy. We just haven't been in the right place, at the right time, with the right people yet. We are heading to the club again tomorow night though, so you never know...
