This is a well-written story in the Swarm Cycle universe created by author Thinking Horndog.
The main characters - Scott, Rachel, and Shannon - are well defined, and the story develops nicely as it moves along.
This is nothing like some of the rape-oriented pickup stories; there's an actual story, not just a bunch of heavy D/S vignettes.
The story deserves its rating as one of the better stories in this universe. It's very readable and there are minimal typos, so if you are interested in finding additional stories in this universe after reading the highest-rated ones, this will fill the bill.
