Try downloading NhGen from SourceForge. It reads database schemas and generates Fluent mappings and classes etc. While all the code might not be what you need, it should start you off in the right direction as it supports composite keys and represents them as separate classes off the main entity.

I beleive it uses a syntax similar to

 CompositeId()
            .ComponentCompositeIdentifier(x => x.Key, "Namespace.Key, Assembly")
            .KeyProperty(x => x.Key.Id1, "Id1")
            .KeyProperty(x => x.Key.Id2, "Id2")
            .KeyProperty(x => x.Key.Id3, "Id3");
