It’s really scary and also REALLY exciting to be confessing!
The first time I really noticed my Mother as a “woman” and not as my Mom, was when I was only thirteen and Mom was twenty nine.
I did not know much about sex at the time and didn’t realize it was my too-hard dick thinking for me. At first she thought I was just going to kiss her goodnight. I put one knee between hers and she automatically spread her legs apart for me. I tried to relax to make it go away before my Mother noticed but it was too late. I saw you all naked in the bathroom and you looked so good that you made me get all hard”. Remember, I was only a thirteen year old boy at the time. I could feel her panties and the bed below us was wet with my sperm, “But I think I made a mess on you”.
Even at my age I knew that most sons didn’t sleep in the same bed with their mothers. Mom had the bedroom and I slept on the sofa in the front room.
I was so sad with dad gone that I would wake up crying at night.
This time she did not close the door completely when she went in.
I looked across the bed and saw that I could see her in the mirror.
You know, like we used to do after Dad died when I was little”. It only took a few seconds for my thirteen year old overly-excited sperm-filled balls to erupt all over her panties. My cock was still hard so I pushed it against the vertical indentation of her panty-covered crotch again and held it there.
