As a 53yo cuck who has been one for over 30 years and sort of knows what to look for when trying to guess hotwives in public...If I saw your wife at an airport or holiday etc. ie: outside of home life... I would pick her to be one who likes to flirt, tease and obviously fuck. She has a sexual confidence to her that I see. At a guess, she got hit up on a lot in her youth, which gave her that confidence, and i'm guessing 'dated' quite a few men before settling down
