When I was about 12 I accidently got to watch my mother undressing. We were on vacation and staying in a cabin on a campground.
It was getting dark and my father was going in to town for a few things. I was going to go with him but changed my mind and decided to play around the area.
I was around the back of the cabin when the light went on in my parents bedroom. I watched as my mother put on her nightgown. My heart was racing and my whole body was shaking as I watched her undressing. She had beautiful tits, 38c, I found out at a later time her size, and a full bush. She was the first real woman I ever saw nude. I was so excited I came without touching myself.
I watched her for the rest of our vacation. When we got home I found a way to watch her and many others. All through my teenage years she fuelled many masturbation fantasies for me.
