Why does my wife want me to have with other women?

Last week I was at a customers home and this lady was making 1 p after another at me. She is a single gal and several years younger than me. I ignored her coming on to me and when I got home I told my wife about it. My wife said you sure missed the boat on that . You should have taken the opportunity and had some fun with her. Since I told her about this she asked me to have with her best friend and even asked me to take her sister out to a motel for . Both of them asked me for in the past. Her sister has asked me for more than a few times over the years and has a tendency to discretly grope me. My wife knows her sister's desire to have with me and is aware of all the . My wife thinks thats funny and errotic. She wants me to have sex with another woman for reasons she can't or won't to explain to me. Is she doing this because she got caught having sex with a coworker friend? Or is she willing to even the score? Or could it be for errotocism?
