The keys are that your story can't exceed 3000 words, it must be funny, it must be M/M and have at least one sex scene, and there must be dialogue that extends beyond panting, grunting and groaning. Oh, no kissing the judges or promising to have sex with them in order to win, because that would be cheating.
If you're interested, get those creative juices flowing because the judges can't wait to read your masterpiece (or is that mistresspiece)? Whatever! We would love to read your entry. Remember - there must be sex in the story.
