Women want what other women have. Your wife has a good friend who's getting some recreational sex on the side. Your wife wants that too and it appears she's getting it. This must be very exciting for you! I think these two women will collaborate and discuss how to eventually spring it on their husbands they've been cheating on them, after they're convinced it's safe to do so. Do you know the other guy? The husband of your wife's friend who's been cheating on her husband?
