In the demographic of people living in power dynamic relationships - Master/slave, Owner/property, Dominant/submissive, Leader/follower - many prefer to pick one side for life and never change. However, a number of people find themselves happily living on either side of that slash, either sequentially or at the same time, with one person or with multiple people. This book shares the stories of the sometimes-controversial practice of living both sides of a power dynamic, in the words of a widely diverse group of adventurous kinksters and relationship pioneers.
