Die Beichte der Josefine Mutzenbacher (1978) - Hans Billian

Review:
(taken from imdb)
Yet another Euro film based on the memoirs of goodtime gal Josephine Mutzenbacher (aside from several softcore, there were also the XXX SENSATIONAL JANINE and PROFESSIONAL JANINE). All credits are pseudonymous in the US video version. Several of the plot incidents are also found in PROFESSIONAL JANINE. Among the familiar set pieces are the party at the tavern, including the orchestra, and the missing watch scene.

Josephine, a somewhat hard-looking redhead in her late 20s (Jane Iwanoff), shacked up with a businessman in the city, gets a visit from her country cousin Veronica, whom she initiates into the trade (though I'd say, watching Veronica in action, that she's been there before). After Jo's b.f. catches them partying, the girls have to make their own way, eventually seducing an *old* guy they meet at a brothel into financing a whorehouse of their own.
