The last story was well received (thanks for all the comments, made my day/week/month!), so I figured it was time for another. This recollection is also 100% true, and takes place at some point in the year after our last story.
When we first discussed swinging and cuckolding, we decided it made the most sense to try visiting a swinger club and just get a feel for the vibe. We drove out to Freedom Acres (we lived in the Los Angeles area at the time), very nervous (I was shaking, honestly), and ended up having a great time just watching other people have sex. We got turned on enough that she and I fucked in front of a room full of people. It was GREAT, and we attended parties at FA like this a couple of times, watching and being watched, but at this point we hadn’t messed around with any other people at the club, just the two of us together.
After having had our first threesome where I got to watch her blow another guy (see our earlier story, linked in the comments), we were open to more encounters like that. FA had a Sunday party that admitted single guys so we decided to give it a shot (the party started early, like 3pm, and that was honestly right up our alley as well, haha!).
