"Brat"

In this short story, there's 2 people a man and woman who go by Xander and Raven. There's a lot of sexual tension between the two, one is extremely submissive and desires the other, and the other is crazily dominant and wants to pleasure the other. However neither of them know that they want each other, that is until one of them makes the first move... and near the end there's a twist but i reckon you'll see it coming half way through the story.
