The first story that I ever published on Amazon was called "Superhero Seduction." It was more a female muscle story than a giantess story, but this story takes place in that same universe. At the time, I intended to do a sequel to that story about a super villainous, but the story initially sold very poorly. I think it was the worst selling story of my first nine or so for quite a while, though it did become a steady seller in my back catalogue eventually.
There is no reason you need to read that story to understand this one. They both take place in the same universe (a pastiche of the DC comics universe) and characters that appeared or were mentioned in that story make a brief appearance in this first chapter. I just mention it for context.
This first chapter is heavy on building up the character relationships but don't worry, there will be more domination and some growth in later chapters. The next thing posted after this will not be chapter two. While writing longer stories I am going to alternate for purposes of the Patreon, so if you aren't really super into one story there will be something else you might like better going on at the same time. Also, this will be the first series where chapters won't go up on Amazon or Smashwords or any other format until after it is finished and collected for one volume.
