Help needed for vintage german movie

[VintageGino]

I'm looking for the title or link to this german vintage 70s movie.
I remember it includes a family with a young blonde actress who has multiple scenes, one shower scene with this maid

(This is the first scene of the movie)
and other also has threesome in the movie.
I don't speak german but there is a guy in the movie who keeps showing up taking photos of the sex hidden like a stalker.

And there is an orgy scene with hippies

These two clips I have found so far but I'm still looking for either the full movie or more clips from it or just if you know the title. Any help appreciated!

This sounds like Ich, ein Groupie (1970) by Erwin C. Dietrich. The hippie orgy and travel style match, but some details might be from a different cut or similar 70s sexploitation film.

Hippie scene is from Imperial Film P771 - Pfeifenschaum

There is a movie Sherlock Fuck at jeedoo, but the names and images on the cover are nonsense:
