German is an fantastically erotic language. I am a native English speaker. But I do speak and understand German to an intermediate level.
It is a great militaristic language as well. I love reading war novels in German, but that is another matter. So back to Deskbabes.
So the phrase spoken by a pretty female like "meine muschi ist feucht. Weurden Sie mich bitte ficken mit deinen grossen schwanz" is much more erotic to me in German than hearing the same phrase in English. In English it would sound tacky and contrived. It probably sounds equally tacky and contrived in German as well. But because German is not my mother tongue, I can appreciate it more.
You mentioned that it sounds dirty in Gewrman. Well, I think that is exactly the point.
I have bought the Pussycat card, but not downloaded it. So I will hear what it is like eventually.
I am not overly happy with the sex talk in English any of the cards I have so far, including those by Davon Kim, Jana Cova, Sarah and Natalie which have generally received positive feedback. I personally find it contrived, although I recognise that others like it.
That is why I prefer the simple moaning of Monica Sweet.
