Not really into incest fantasies myself; however, for my fellow forumites who are, I offer a video.
Girl comes home and goes into her parents' room to find dad sleeping naked under a sheet. She decides that this is an excellent opportunity to check-out a male's equipment. After playing with it for a short time, dad wakes up and proceeds to show her how well his equipment functions in her mouth and pussy. She offers a little resistance at first, but quickly becomes reconciled to what is happening given that she really was the one who started the ball rolling. Preview pics below.
