Ellas Step-Daddy Desires

Dear Diary, I have always been a very shy girl and my older step-sister Emma was the outgoing cheerleader in the family. Every now and then I'd catch glances between her and our step-brother but I was too naive to see the truth until one day when I caught them fucking in a classroom. Emma swore me to secrecy so Step-Daddy wouldn't find out and told me we'd talk later. When I went to her room I heard moaning and peaked through the door. Imagine my surprise when I saw Emma was fucking Step-Daddy. I was shocked and aroused at the same time but instead of leaving I kept peeping through the door. I started touching myself through my dress and imagining it was me Step-Daddy was fucking. The thought of him enjoying my body was so intense I came right there in the hallway. I think theres something wrong with me. More Later Ella
