The Priestess by Jacueline Bellevois
This an excellent book. It features a rather innocent young solicitor who is seduced by two very attractive and sexy girls in his office. He is sent to investigate the dealings and finance of a rather dubious nightclub and meets further very dominant women. The fem dom scenes are very well described and unusually the story is very exciting as the hero struggles to escape from the various dominant ladies. Altogether a very good read.
