to 2kinkySoldier :Find a local swingers club near you. That's how we got started. They're all over the place in the US. And a lot of the wives at those clubs are bi. If you don't mind the husband watching.
to find them, look up "North american swing club association" I can't post a link here.
When I finally convinced my petite filipina wife to try black cock, I surprised her by bringing home three young black men to make sure that her first BBC expirience would be one that she would never forget.
