What's on your wife's mind? ⇐ General

[Anonymous]

The gist of it is this:
We accidentally ended up in a nudik - she was the first to undress, I noticed that in the nudik she was trying, as if on purpose, to spread her legs wider so that everyone could see, and she was always so wet. He started a conversation and admitted that it excites her to show herself. Then he started talking about swing, asking if he wanted to try it, she said she didn’t mind, but only soft swing (this is when there is no exchange). With the exchange the refusal is categorical. I also mentioned once that she was watching gang-bang porn on her phone. At this point everything went quiet. She herself doesn’t talk about a group sex, but she wants to go with an exchange. Sometimes during sex she reaches out with her hand towards the phallus, and once sucked on it. How should I proceed? I won’t lead her by the hand to another couple.
