Розы и линии / Rose et Line (1978)

This title is mentioned by Egafd both as main movie (Pierre B. Reinhard) and as alias of Cette Salope d’Amanda (Francis Leroi)
Although Francis Leroi appears as director onscreen, this movie has nothing to do with Cette Salope d’Amanda and the cast match perfectly with that of the main movie.
Movie border-line soft/hard, maybe it was deprived of explicit scenes to create a soft version.
