Well, that's honestly the logical conclusion to the current trend. I am surprised this has not happened sooner, what with "write what you know" being a major tennant of the writing craft. Ian Fleming wrote about spies and sentient cars, Stephen King writes about killer shit in Maine, why not have a porn star write about the beast with eight backs, four fronts and something called "The Zamboni Surprise"? I hope this starts a trend with Mary Carey writing a political erotic theory about running for the governor of California. Shit, Arnold Schwarzenegger already did that.
