I don't get it. Why German? Don't get me wrong, I love the German language. It's a perfect language for epic poetry, verbose monologues, witty remarks, and especially for almost excruciating officialese. But in my opinion it's a really shitty language for porn. Most of the time it sounds really stupid, embarrassing or downright silly. There are very few exceptions (for example some of the Denise la Bouche stuff).
It's the same with Spanish. A really nice language, but Spanish porn...
