Hi.
Answering this part: "If I had of been there, I would not have left. I probably would have taken the kids outside and kept them entertained until a real life adult with a maturity level came out and took them home. THEN I would have grabbed my coat and my Dog and headed out the door."
This is
kind of what happened with us. For a lot of the early part of this, because it felt way too weird to mix swinger party with kids present, I ended up playing ball in the yard outside with the kids. To be honest, it was the most fun I had at this party. They were sweet kids.
We had just come inside for a few minutes at the time of the topless picture-taking & women rubbing each other, followed by us blocking the little guys from seeing in the glass door. It was a knee-jerk reaction for us to look behind us and
think about those kids when we saw what was going on. It bothered us a lot that their own family didn't seem to care as much about them.
Within a short time before we left, this is when we learned that (1) the kids were sent home alone, (2) the drugs came out, and (3) their parents were drunk and were about to get high, too. They had it in their hands as we were leaving. Unfortunately for those kids, "a real life adult with a maturity level" didn't materialize for them to take them home.
When we first arrived and saw the kids and asked about them, we were told they were leaving any minute (with their parents, we thought). That's pretty much why we stayed and tried to make the best of it, thinking that "any minute" this party would be changing gears and we could get more comfortable there. They kept repeating "any minute".
This is the first time we'd been at something like this with kids there. It took us by surprise. If we had known they would be there, we wouldn't have gone. We know of another group of people that do (or did) have combo family/swing events together on purpose, like cookouts, because (they said) it's hard to get babysitters. GAG

We were actually invited once by that group and wouldn't go there if they were the last swingers on the planet.
About this: "She said not problem, we can go to MrDonalds and the kids can play. I know she isn't ignorant or stupid, I also know that it was vanilla, with no sex talk at all, just get to know you stuff. But even that made me uncomfortable."
That would have made us uncomfortable, too. We would have asked for a different time & place to meet, too.
