I agree. Guilt.This is a classic case of guilt and shame she's feeling. She gave her little married pussy to somebody else, had fun but then started feeling regrets. No way she wants to tell you right now because of how she's feeling. The good news is she will get over this guilt and go back at it. Maybe the guy she let fuck her turned out to be an asshole or something and made her feel bad. It's difficult to say. That said, you can be confident now that every time you see her little ass and pussy you know it's been given to somebody else. That mouth when you kiss her, you can just sense there's been another guy's cock in it and he enjoyed your wife's mouth and pussy immensely.
