Amy's Mom, which has become my best-received story, was inspired by "Stacy's Mom" by Fountains of Wayne. Other than that, most of my stories have been inspired by events or people in my past life, and by sexual encounters that didn't happen. In particular, as someone who enjoys hiking, biking and skiing, I've drawn inspiration from those activities for many of my stories, including the new Sexsquatch and Persistent Terror.
Now that I've covered a ton of my longstanding fantasies, though, I feel like I've been branching out this year and finally drawing my inspiration more broadly and less from my past, including characters not based quite so directly on individuals I've known. Steam Mates was inspired by a trip to Portland and by the music, movies and events of 1972. Heartbombing the Heartland was inspired by numerous car and train trips across the Great Plains over the years but is firmly set in the present. Fair Fare Trade was inspired by an olfactorily overwhelming visit to a county fair not too long ago. Stan Bi Me was inspired by some of my favorite rock bands of the Seventies, Eighties and Nineties, especially the criminally underappreciated L7 (still touring!). The cover band Ronnie Rockett and the Black Tarts in that story, by the way, was inspired not only by Joan Jett, but also by (again, criminally underappreciated) Living Colour.
Sneak preview: I've been reading not only a fair bit of science fiction, but also I Eat the Stars by Sarah Wilson, a guidebook of sorts for navigating the looming threats of societal collapse and human extinction. Both have provided a ton of inspiration for Wife Hacking, my upcoming competition entry.
