We have a very large friend group from our kids growing up. No swinging. But there is one couple we like and we flirt with a lot. Privately. We went out last night to a concert. The two couples and one other woman. Mutual friend. Wasn’t planning on it but both of us went a little farther with the other couple. It was a lot of fun. Here is the problem. The 5th wheel caught my husband and the other wife making out. She of course assumed she caught them cheating. She is not a swinger and I am sure she will judge. What the hell can i tell her? I really do not want to be completely honest but I don’t want her thinking my husband cheats on me.
