I'm gonna be writing my first real erotic story for submission! Squee~

I've done a lot of RPs so I know what I'm doing more or less. My only issue is I'm in need of subject matter / inspiration / etc. Any suggestions would be much appreciated. <3 Even requests! I'll do requests, it's a lot easier than having to think of something all on my own. The more detailed the better, but even a general push in a certain direction would help.
