Each story basically corresponds to a scene set in the past. It is well written, printed, and thoughful for this style of erotica. Most of the stories concentrate on the psychological aspects of SM and not on describing the imagery of a scene.
Some stories are heterosexual and some are homosexual with both men and women as tops andbottoms.
It is written in sections covering everything from simple knots and restraints to branding, cutting and leather clubs. It is a very well written book and covers alot of ground. If you are looking for answers to why you have always thought rope or leather were exciting, this is the book for you. If you are looking for naughty stories, pick something else. Rather heavy reading at points, but overall - very informative.
