I started dating my wife when she was sixteen and I was eighteen. Her little sister was six, so she became my little sister, too. As our relationship developed, I was like a hero for the little Anna, and she kind of fell in love with me as well. Nowadays, while Anna is thirty, I edited a sensual photo with her face and emailed it to her. She replied by saying she liked pretty much what I did, but the girl in the original photo didn't look like her. So, she asked me to do it with a more looking alike one. This was just the beginning of an email relationship of sexual fantasies between her and me. For every picture I send her, she comments back expressing her satisfactions and desires. We have never talked about this when we visit.
