For me, it always starts with some fantasy about the method of transformation. When I wrote ‘Control Yourself’, I was thinking about cock cages and what a chastity curse would look like. When I wrote ‘A Stranger Comes to Town’, I was thinking about transforming men entirely by changing their attitudes and fetishes - though that obviously evolved as the story went on. When I wrote ‘Welcome to My Party’, I was thinking about an app where you could photograph men and tweak them to your hearts desire.
Once I’ve got the method of transformation, I start thinking about characters. Who would actually be motivated to use it? How would they want to use it to their benefit? How might it go right and how might it go wrong? In general, I like underdogs using the transformation to become hotter, cooler, more popular, etc.
For ‘Control Yourself’, I made the protagonist a nerd who wanted to be cool but never figured out how, until the transformation gives him the boost he needs. For ‘Stranger’, the protagonist is the devil himself, using his abilities to destabilize the balance between good and evil in an area, and in turn using that result to find his way home. In ‘Welcome to My Party’, the protagonist is an uber nerd who can make technology do just about anything, but he wishes he had friends.
Once those things are in place, I carefully write the first… maybe 300-500 words? I put a lot of emphasis on making the characters feel real and interesting, giving them their own little quirks, making sure that the story has the right beat and rhythm to draw in a reader.
And then I’m on a roll. Then I just keep typing, always trying to follow the decisions that these characters would actually make. Sometimes I get stuck, and I realize that I’m trying to force the character in an unnatural direction. Sometimes I can’t stop typing until I’m done, because dammit, they’re telling me exactly what happened and I probably only get one chance to write this down.
And honestly… I start three or four times more stories than I ever finish. I think it’s totally okay to put down a story if it’s not working, if the characters lead you in a boring direction, or if you just aren’t having fun anymore.
