My Mom

When I was 15, my mom and I were traveling and stayed one night in a motel. As I was surfing the channel on tv, I came across porn. My mom saw and said It was ok and started watching it with me, I soon got hard and mom noticed and asked if I would be more comfortable if I took it out of my jeans. She smiled and said it would be our secret. I did and she remarked at how much I grew since I was a baby. She said it would be ok if I stroked it in front of her, I did and she slipped out of her clothes and took over for me. She made me cum and told me to promise never to tell anyone. I kept my promise and 4 or 5 times a year she masturbates me . I'm 50 now and she is 75 and she still does it for me.
