Some time back I had a friend named Lana who was also in her 50s. We used to talk on the phone and sometimes spoke about sex, what she didn't know was that I was seriously jacking off while we talked.
As time progressed we became more familiar and more frank with each other. After, I got her to start masturbating as I was stroking my cock while we talked on the phone, it became something I really looked forward to and we did it at least once a day.
Let me describe Lana. As I said she was in her 50s, she has a beautiful face, she is a brunette with shoulder length hair, she is kind of plump, but not overly, and she has beautiful huge tits. Fantasies about her tits were part of many of my jack off sessions. She has one of the most beautiful natural pussies I have ever seen.
One year she invited me to her house to celebrate Mardi Gras with her. Needless to say the hand-jobs and other sex with her was fantastic.
Since her home was near the Mardi Gras parade route we could go to her home to use the bathroom, get refreshments, etc. On one particular occasion I went to her home to use the restroom alone. I found a pair of her used panties, immediately got hard, and used the panties on my cock. The feeling was so fantastic that I had one of the most exciting orgasms, and came in her panties.
Later after the parade, we were back at her house and she told me she found the panties I used. She said she would not be upset with me if I performed the same act for her while she watched.
I immediately shed my clothes and stood naked in front of her. She took off the panties she was wearing and handed them to me. I wrapped the panties around my cock and jacked off again until I shot another huge load into these panties. What an orgasm, I must have shuddered for a full minute. I still get hard thinking about those great sexual times.
