I've only did this outside the hobby. I got picked up by a couple in a bar one night. The husband wanted to see his wife with a black guy. The wife was hot. Nice MMs (sounds like a review). That was a fun night in a little country town.
The only drawback was that they lived waaaaaay out in the country. But I was dumb and in my 20s. It never even crossed my mind that anything could go wrong (like getting lynched--we black people are sensitive about that shit).
But it was awesome none the less.
