It was growing in my mouth with each passing second until he was fully erect.I took it out of my throat to get a better look at it and it was huge! It...had been the first cock I had seen besides my own in real life but it was so much thicker and longer than I was. He noticed me staring in amazement and said "you like this black dick huh?" And for the first time I spoke "I've waited so long for this" and dropped back down to continue sucking on it. I had watched so much porn I tried my best to. I worked up my own story of whatever that stuff might have been as I stroked myself.Later I found some other photos Mike had hidden away. One showed her much younger, in bra and panties, smiling. Another was her lying on one elbow, her robe open showing her breasts and a bit of pubic hair. I was riveted, and my cock began to fill my underpants.I wasn’t a total idiot. I put the photos back where I found them and I didn’t say anything about it to Mike. But I was pretty sure that four photographs. I knew both my parents were swingers, having caught them fucking other people several times when they thought I was sound asleep in my room and I had even found hidden and watched video tapes of them fucking each other as well as other men and women they met somewhere or other! From the videos and pictures I had seen, I knew my mom was a total slut and she did some things that shocked the piss outta me and even my dad was kinda wild and I once even saw him eat the cum a man had deposited inside. It was past nine when the sun was high enough for a few rays to stream through the window shutter, illuminating Anna's face. She was a beautiful girl, and when she reached her full bloom in a few years, would be almost a goddess. Her eyes opened, and then she remembered where she was, and why. She smiled. She curled a petite hand around her father's still slumbering form under the sheets, gently taking hold of her father's organ. It was already rock hard. She stroked it gently, not wanting to.
