I just love watching my wife with a woman although she doesn't let me watch often but she never lets me watch when with two mainly because the other two won't permit it!............Alice why won't they!
My wife & I have a close friend that we jokingly call my "second wife". I've been wanting to fuck her for years but out of respect for my wife have never acted on it or even talk about it. OTOH, if my wife were to offer my services to our friend for a weekend, or mention the idea to me, I would gladly go for it! There was a point in time where my wife suggested we bring her with us to our favorite nudist resort for a day but unfortunately that never happened.
