I knew that this was 'adult' literature but Holy Cow.....!!
The 'adultness' begins right there on the first page and never lets up. The 'story' holding the various erotic scenes together was minimal with no plot or character development but then that is hardly the point, is it?
From my limited experience I would say it was pretty competent as erotic literature.
It is not really a book you would read for its literary value rather something you would dip into to spice up a boring afternoon.
