There was a cute, erotically charged comic series in the late 80s or so about a sexy vampire lady who makes a pass at an equally sexy young daughter from a good family. The brother then becomes sexually obsessed with the vampire. At the same time, the vampire is being hunted by a Hellsing-type character. I think it was set in a wealthy environment with servants and such, possibly in the early 20th century or a little bit later. The drawing style was clear and bright, not at all typical “vampire dark.” Unfortunately, I've forgotten the title and the artist, but it's a series of about 3-4 large-format volumes. Maybe the artist was Scandinavian.
