This is a series of side-stories to Dash of Humanity. Each chapter title will be numbered to show which chapter it follows. The first chapter, 4a, occurs after the end of chapter 4.
Reading the original is encouraged so you get the premise and the setup. This story expands the innuendo of the teen version into short stories about Don exploring Dash's sexuality, and the sexual warfare that ensues.
It's not going to have any ground-breaking revelations to the main story in order to keep it optional. Hopefully you will find some amusement in the gender-bender humor and other sexual escapades contained within.
