For context, my wife and ai have only ever been woth each other sexually, and we've been married nearly 20 yeara. Last year she and I began openly discussing our more hidden fantasies and my wife surprised me by bringing up that she is turned on by the thought of me being with another woman while she watches. She has a passing interest in women and has said if it felt right, she would be interested in joining, but for the time she's perfectly content to just watch and do her own thing. We've had the discussion several times and both feel comfortable enough that we'd like to act on it but in a safe and comfortable way.

In order to fulfill our fantasy we've begun talking about visiting a legal brothel or hiring an escort. The way we see it is, we're hiring someone for their services and nothing more. This way we remove the chance of it being anyone who could potentially become romantically involved for obvious reasons. So my question, has anyone here had a similar experience? If so, how did it turn out?
