My wife's high-school girlfriend comes to town about once a year to visit us. Each time she makes it clear she wants to get away from her husband for a while. My wife had occasional sex with that girlfriend before we got married. Neither of them says out loud that they want to have sex with the other, maybe because all parties are shy and assume correctly that my wife and I are happy together. I don't want to be with the friend unless my wife is there. Last time the friend visited, I accidentally discovered she brought a sexy nightie. But it was a busy weekend, there was no time for play, and she didn't mention it. Do you think the friend is open to a three-way romp? Maybe the friend was just hoping to bed my wife only? Who should ask her, my wife or me? Who should say what?
