There was a story on this site called "The Lost Notebook of Doctor E," with possible variants being "Journal" and "Professor."
Basic plot: A teen finds or comes into possession of a notebook or series of notebooks, containing a formula for a drug that either drastically reduces inhibitions, or increases suggestibility, or both. He uses it on stepmother, step sisters and sister. One sister winds up as a dominant lesbian or bisexual, another as a submissive. I don't recall if it was a completed story or not.
It doesn't appear to be on this site anymore. Anyone know where I can find it, or does anyone have a download they can share (legally, I'm assuming)?
Any help would be appreciated.
