I lived with my sister and her husband years back. I worked nights and he worked days. One morning after work I was laying in in my room watching a brother and sister incest movie and my sister came in and started watching it with me. We both looked at each other and started doing what was on the movie. As I pouring the cock to her she started moaning and said she was coming. I made her cum about 7 or 8 times. When I was about to cum she said she wasn't on birth control and rammed my cock up in her as for as I could and fertilized her egg. We fucked every day for about 3 months and shot my load in her everytime. She had a baby boy . Her hubby thinks it is his but I know who the dad is. I can't wait until they want another baby so I can impregnate her again!!!!!!
