Let me make myself clear from the beginning so nobody can use this as "ammo" in feedback: my advice is not for everyone. I understand that no two writers are the same, and I accept this fact with good humor and without blame. Nevertheless, there are trademarks that certain authors may adopt for their own, and one of them is quality writing. This is a hassle to many authors; a quantity of quick, easy, dirty stories will rake in more readers and more points than a novella the author poured her heart into, and it's less painful to get flamed. I'm a masochist, so I pour. This essay is not for the quick-and-easies out there, this is for the fellow masochists who say "Please, let me create a piece of work that I can call erotic art, not a cum tale."
So now that I have guaranteed myself an inferno, let's get started! I'm sure the reader of this article has read at least ten Lit stories recently. Remember those stories? Did they have a paragraph that went along the lines of "She was 5'4" with 36C breasts and long blonde hair"? I will bet you that 9/10 do, and I'm betting conservatively. To me, that gets old very quickly, and I'm talking about the fact that all that description is in one big paragraph, not the unrealistic perfection we all try to capture in our main characters. Admittedly, it is nice for the instant gratification crowd to immediately "see" the soon-to-be-fucked heroine of the story. Let me repeat, this is not bad! If you write to get as many people off in the shortest amount of time possible, this is a pretty good formula for you. No thought process is required for the reader or the author, and that can be reassuring. You may depart this essay without even leaving a rating.
However, if I still have your attention, let's explore an alternate route. Instead of telling the reader about your main character (and the subsequent ones, too) in one blunt, fast-paced, predictable paragraph, why not make them wait a little for it and piece it together on their own? Chances are, the reader will become much more interested in the story because a.) it isn't like every other one they've read, and b.) it's more realistic. That summation paragraph (henceforth referred to as "The Paragraph") puts the story on "freeze," and displays the heroine on a revolving pedestal: "And here we have exhibit one: a 48D female with a curvy ass and an 80's perm." It's like a traffic jam. It's unaesthetic and boring, and if you put just a little more time into it, you can easily change it.
