My wife and I have been happily married for 4 years. No real fights everything is great. We have two beautiful girls together. In the past year and a half we have become extremely good friends with another married couple. My wife and the woman have developed a crush on each other. My wife and her think it would be fun if they made out while us the husbands had sex with them. They asy nothing other than making out. My wife says she has no interest in the husband and it would be better if it were the 3 of us. This obviously would never happen. Just interested in opinions.
