This story started as an entry into Chuck Wendig’s weekly flash fiction challenge, but due to various reasons I ended up missing the deadline. So I went ahead and started rewriting it to increase the quality. The challenge in question was to pick two genres at random from a list of 20, and write a crossover story in 1,500 words or less. As luck would have it, I ended up with “Parallel Worlds” and “BDSM Erotica”. The way forward seemed pretty obvious from there.
