24f first night at a swingers party

My husband and I wanted to get involved in the swinger lifestyle in our area. Pretty rural so we knew it was going to be older couples but we were okay with that. We even joked like we'll be the hottest ones and they probably are pretty good at fucking it will be low pressure for us. We found them through here talked back and forth a bit and our first invitation was just me. They were like this is how we do it, often it's just a guy convincing the girl and she isn't very enthusiastic and it ruins the experience so we invite the girl first if she enjoys it and we enjoy her we invite you both back. My husband didn't like it but we wanted to get into the parties in the future so we agreed. When I got there it was what I expected. 8 couples ranging in age from late 30s to early 60s. We talked and drank a little bit flirting which was funny. They weren't ugly but I was attracted to any of them but the whole time was thinking these guys are going to be fucking me if not tonight in the future. As things turned sexual one of the wives started explaining to me how the night would work. She said it's your first time, your try out. You are the cum queen. We all have our separate fun but when one of the men are ready to cum they get to inside you. Everyone had to bring an up to date STI screening. I said I am on birth control so that is fine. It was a lie. I wasn't. My husband and I used condoms. For the rest of the night anytime one of those eight me came it was inside me. Towards the end I was doggy style on the end of a bed getting a creampie train run on me. More men showed up throughout the night. I ended up having 15 different men cum inside me.
