Public sex nude beach location?

[snowbass]

Can anybody say where the public sex at the nude beach is filmed?
Any chance of going there to watch some scenes being made?

It is a nude beach in Brazil, there aren't many so it is easier to find on Google. We do not want to make a lot of publicity for it as it is mostly visited by locals and we won't communicate when we are going there for obvious reasons.
