Not too dark! My kind of story!
She walked to the mailbox feeling both excitement and dread. Surely this time he would get the message. Surely this time he would know how much she loved him. Erikka had fallen in love with Sam 2 years ago, when she babysat for his family. He was so tall, so handsome, so strong, such a good father. Too bad he was married to that whiny little bitch. She had tried before to show him the difference between 'her' and Erikka, but he just looked at her strangely. Soon the family had moved away, but not far enough away that Erikka couldn't find them. One of these days, he would know who truly loved him... She opened the mailbox and put in a reminder. Maybe the nude photos she had taken of herself in front of his house would show him how much she cared, how much she would do to make him happy.
