Pete Polly is a pen name of a professional person who started writing erotica for a perhaps odd reason, to entertain a long-distance love interest. What Pete Polly is doing is retelling/rewriting old "Fairy Tales", often thought of as children's stories, roughly true to the original outline, but changing the story and wording a lot, and adding a lot of sex that was not in the original. As time went on, and his work was shared & read by several persons, several suggested he ought to publish them.
