I started writing erotica after reading many stories that made me think, "I could write something better than this." So, I tried. After posting it on another site, and having people ask for more, I kept writing.
'apl' was just a jumble of letters I jabbed onto the keyboard to have a pseudonym. My usual internet nick also ends in 'girl' (as I am one), so I kept it. But I do own (and love) my mac.
