Excuse my grammar, English is my second language

My wife (25) and I (29) started with the idea of having others to join us a couple years ago. In March 2023 we decided to give it a chance. We decided to start with a couple swap but somehow we ended up in a MFM (fun story there, but nothing to do with my question). Then we had a few swaps, a girl as well and more swaps, but not another guy. For some reason guys always flake last minute. Long story short, she got jealous because the last swap the husband was extremely bad at sex and she didn't get to enjoy it, but the other girl said "this is the best sex of my life" and she thought something was going on between us, but nothing more far from reality. All of that happened between March and July 2023. Fast Forward to November 2024, when I started talking about the idea of getting back to the game. Idea that seems to like her when we're having sex, but not afterwards. So she likes to talk about how she wants two cocks for herself again since she only experienced it once. But as soon as we finish, she doesn't want to talk about it anymore. So the question is, how do I approach a second time? First time we both wanted it, but this time is only me except when having sex.
