This is a German softcore that plays out like those assembly-line Cinemax films from the 1990s. So imagine that those Cinemax films had been made by Germans, and you should get the idea. I gather that it is part of a group of films to be produced by Amazon in conjunction with local German studios.
Very few people have seen this film (9 votes at IMDb), but film-rezensionen.de reviewed it in detail. Their summary:
Un/Dressed is just trivial glossy kitsch, accompanied by cuddly music that doesn’t really get the pulse racing. Even if the erotic scenes had been exciting, they would not have been enough to make up for the dreary rest.

I think you mean the Cinemax films from the 90s. Most of the 80s Cinemax stuff I think were movies from Europe.
You’re probably right.
Very nice ass

It’s a shame that Cinemax was destroyed by HBO executives. Even their newest shows that came out a few years ago like Jett had a lot of female nudity, but the gays at HBO didn’t like it so they killed the channel.
