When she was young, Elaina would often share the outdoor shower with her dad after a day on the beach. It was all very innocent, but seeing her father's 'penis', as she later found out it was called, left a lasting impression on her. As she got older, she wanted very much to see it again, and not just to see it...
Chris is your average 16 yo who just moved into a new home with his divorced mom and twin sister. While talking to his attractive neighbor, a wasp flies up the leg of his shorts and stings his dick. So naturally his dick grows to twice its size and his pheromones and testosterone to go into hyper-drive (its a porn, what did you expect). Starts off as mindless stroke story, but plot and character development really improve a few chapters in.
That probably wouldn't have been how Maria would have described it as she lay on the floor, nursing her injured hands. But when she got back from the hospital and realized that she couldn't take off her own panties, possibilities did start to occur to her.
It didn't take long after I first had sex with my dad my mom joined us. Imagine my surprise to find out she was an incest daughter as well! Her first experience had been a lot different so she wanted to be sure I things were better for me. Now that everything worked out it was time for me to learn what she had kept hidden from me all these years. I had never really given any thought as to how having sex with your mom would be different than being with your dad - beyond the obvious.
