I know this is probably hopeless, but does anyone remember a story on Literotica about a couple going to a nude beach, and the wife seeing a big black man in the distance and sending the husband over to bring him up. The black guy's dick ends up getting hard the closer he comes to the wife, and it turns out they both work in the medical industry, and they go odd together as the husband/boyfriend lies down in the sand and comes while thinking "sweet humiliation" or something? I swear I'm not nuts...
