Venus in Furs.

This is the story of two generations of men, a father and son, who fall in love with the same woman. The father, a widower, can't seem to move on with any other woman until he meets a beautiful girl who calls herself "Venus". As she reawakens the erotic desires he thought were gone forever, his son is falling in love (and lust) with "Vickie". But, what starts as a casual erotic encounter with each developes into a deep but troubled love triangle when Venus and Vickie meet face to face.
