Frithjof Klausen and Patricia Rhomberg as father and stepdaughter

Yes, here it is, the German Sex Classic and first film about the turn of the last century Austrian Viennese prostitute and
legendary Bordello madam Josefine Mutzenbacher, and based on the novel about this, maybe, historic actual person..

Josefine Mutzenbacher: Wie sie wirklich war (1976) directed by Hans Billian and with cinematograhy by Gunter Otto.
Released in the US as "Sensational Janine" this XXX hardcore movie is considered to be one of the best porn films of
all time, and here it is in it's uncut glory with an english or german audio with english subtitles.

Lots and lots of sequels were made, and the first of them was "Sensational Janine" in 1976 directed by Gunter Otto, but
the legendary star of the first film was Patricia Rhomberg and she only appeared in the first film of the series. It's said that
she was the girlfriend of director Hans Billian, made a few sex movies, and when they broke up she returned to her regular
job. She was no classic beauty, but she was intensely alive in this film, lusty, luscious, bushy and beautiful. A Legend.

Josefine and her stepfather, having an unhealthy relationship

This unique erotic film has a lot of normal ugly people having sex, many quite old and in their middle-ages and some younger
and beautiful as Patricia, she was 23 when making this film i think someone wrote somewhere.

The film starts with Josefine looking straight at us, the camera, and telling us in a Flashback how she became a prostitute and
reached the peak of her profession as a Madam of a Viennese whorehouse. It started when she was 16 years old and her parents
had a room rental service, and when she peeped on her mother and stepfather having sex, and everyone having sex everywhere.
Josefine loses her virginity to the beer delivery man (Siggi Buchner) and she then proceeds with attacking their room guests
as she really enjoys this new hobby of hers. She's unsatiable.

The film is presented in 4:3 (i think, maybe 1.66:1) and with english or german audio. Two of the bonus scenes, one at the police
station and one at the pornographic studio are only with german audio.
