Review: 2,4 out of 10
First of all, I am from Germany, and I grew up with titles like
- Liebesgrüße aus der Lederhos'n
- Schulmädchen/Schoolgirl Report (https://www.avsubtitles.com/movie.php?movid=2610)
- Kasimir (https://www.avsubtitles.com/movie.php?movid=2510)
... and some of the sentences (writing) I can remember to this day. I used some quotes in my personal life as well.
Soft- or hardcore comedy depends on the writing and the presentation. Both are awful in "Nackt und keß am Königssee".

It is one of the worst movies I have ever seen. It's almost 90 minutes long, and the first 25 minutes reveal everything that is wrong with this movie. One sex scene stretched over 18 minutes, but in real time, it is 3 minutes, 12 minute break, and another 3 minutes.

The bar fight doesn't make sense at all. Perhaps it's a parody on Benny-Hill-Slapstic or like "Utz-Utz" (two strikes) by Bud Spencer and Terence Hill, but the sound is awful. And the brawl does not support the story. A cake in one face ... well, I don't think it's funny.

Kasimir (https://www.avsubtitles.com/movie.php?movid=2510) was produced in the same year. Kasimir is a bailiff who visits Ursula Berger. She doesn't want to give him the TV or other items, so he impounds her ass. Ursula will sell her holes to a rich buyer. Then her debt is paid. And of course ... Kasimir has to test the merchandise first.
"I hereby protest against your desire to use my hole."
"I am sorry, but your ass now belongs to the German Republic and therefore it's not your decision what happens next."
Funny, good writing, and a great sex scene.

The lesbian sex scene is okay, not great, but okay. You have to wait one hour for the first good boy-girl scene. And it starts with some horrible kissing, which is totally unbelievable. But you find that a lot in older porn movies.
The girl is having fun, and you could have used her own moans/voice. But the director decided otherwise. Music and standard moans, which repeat themselves after a while, were used as the audio track. AWFUL!
