Downloading X-Change Temptations: Gender Transformation Erotica (The Investigation Book 1

I'm a private eye, and I've been hired to track down a missing addict. The strange thing about this guy, though, is that he isn't addicted to drugs. He's addicted to a new pill called X-Change. Supposedly, it's a secret new nanotechnological marvel with the capability to microsurgically alter you into the opposite gender for twenty-four hours. Why do I have the feeling I'm going to get in over my head with this one? Content advisory: contains strong sexual themes of gender transformation, gender dysphoria, and some seriously weird hijinks. ~50,000 words.
