This book is based on that split decision moment when you decide to refrain or give in to something definitively; whether it's cheating, or revenge, or sexual experimentation. Each story builds up to a decision, then allows the reader to select the direction. It's an opportunity to explore kinky realms without real consequences. The word "flick" by definition means a sudden movement or to propel as such. In this instance, the reader is propelled into fetish.
