Okay, here's the rest of the story. I suspect I was there to prevent the full on nude wife swap party the other folks had in mind and they talked about that **** because they were pissed it wasn't going to happen. I honestly, going in, had no idea why I was invited to this thing at all. It was my mom, my dad and my mom's work friend and her husband. I can only come up with me being there so that some kind of orgy didn't happen. The other couple basically suggested the nude orgy could go on except that I would embarrass them all with my young tight body.
As far as I remember my parents never hung out with them again. I always assumed it was because that other guy made a racist comment and my parents were vehemently opposed to racism. My parents were, in 100% fact, vehemently opposed to racism. But maybe they also didn't like those guys making sexual suggestions about their 15 year old son? I didn't think about that because I was too busy beating off to the idea of banging my mom's work friend.
