Querfeldein (2006)

A customer goes on a jaunt into nature with two hustlers. His goal: sex outdoors. But things do not go as expected. They get lost in the forest and have to spend the night there together. Suddenly they are no longer just suitors and hustlers. They involuntarily get to know completely different sides of themselves, because the old rules no longer apply.

Unfortunately the movie Querfeldein is not yet available on HBO Max.
