All references made in this story took place when I was 18 years old.
I am one of those guys that is blessed with a well above average size cock. Both in length and girth. But my story goes back to when I still lived at home with my single parent mom even though I was 18. My mom was a very attractive woman and desired by many men, and probably a few women. Mom was about 5foot 06inches tall, had long brown hair, blue eyes, incredible legs, an even better ass, and big tits. 38D size tits. On a few occasions when I got a look at her tits I could see that she had large areola with big hard brown nipples. Mom had no trouble finding men that craved her and dated often, even bringing men home on several occasions.
I found that I was a bit jealous of other men having sex with my mom. I use to lay in bed and listen to her with different men and jerk off as she was getting fucked, moaning quite loudly when having an orgasm. I was pissed because she was my mom, and I was the man of the house at 18, and I wanted her as well. My mom had no idea that I wanted her, so I set a plan in action to secure her affection not as a mom, but as a sexual partner. I knew that she liked having a hard cock fuck her and I doubted that any of them had what I had between my legs. I have 9 and a half inch cock that is two and a half inches in girth. Many women have a hard time taking it all, but I was hell bent on making sure that my mom got a good look at it and gave me a shot at fucking her.
So I started wearing short gym style shorts around the house that not only showed the outline of my cock, but also loose fitting legs so I could let my cock show out of the bottom of the leg. I made sure that I wore them every evening when mom and I were watching tv in the living room. We were always close, and many times we would cuddle up on the couch together. A lot of the time, mom would lay her head on my lap watching a movie or a show. This particular Friday evening I put on a pretty sexy movie. Mom had her head on my lap like always. It was common for us to watch these kind of movies now and then and joke with each other making comments about a certain scene or person. This particular movie was pretty sexual and not only was I getting a bit hard watching, but I could tell mom was getting a bit horny as well. Many nights after we watched a movie like this I know she would go to bed and masturbate as I could hear her moans. The scenes in this movie pretty much showed all body parts and sex between the characters. As we watched, I got a hard on and the head of my cock slipped out of the leg of my shorts with about 2 inches visible. I knew mom could feel my erection, and I could tell that she had spotted the head of my cock right in front of her. She moved her head a bit and I could see that she was completely engrossed with it. I started pushing upward pressing it more toward her face. I watched as she became quite fidgety and was squeezing her thighs tightly together.
