On the farm where I grw up was a barn where my sister and her boyfriend went in secret to fuck. I had a spot where I could spy on them, and I often went there to watch them. By the sound of it, my sister liked to do it very much. So one day, when I was 18, I took the boy I was going steady with, Oliver, with me to the barn. We watched my sister getting laid, and afterwards I asked him if he would like to do that with me. He said yes, and we started to kiss. I took off my panties and pulled up my skirt, like I had seen my sister do, and let Oliver get on top of me. He pushed his cock in my pussy and at first it hurt, but then it felt really good. After that I did it with all my boyfriends.
