Fun with younger girl

Hi this is my first story but I hope to write more.

A couple of years ago I started talking to a nice girl in her twenties. After a while of getting to know each other she sent me her picture. She was incredible to talk to, sweet and caring, with a great, kind heart. I saw her picture and was completely blown away, she was stunning. I had a partner at the time, but this girl was all I could think about, and we talked often. She found out things weren't too good at home so we began I guess what you would call a bit of flirting that often led to me masturbating while my partner was asleep or doing something else.
We learned a bit more about each other and she turned me on more and more to a point where if I was even out in my car the lube and tissues came with me since it usually led me to getting my dick out and masturbating over her. I just couldn't get enough of her. I would masturbate in my yard, in my car, or wherever I was at the time of talking to her, even parked at the shopping centre while my partner shopped. I masturbated most of the time, and when my partner and I did fuck I thought about my special friend. Well 3 years on we still talk she is still amazing and as an older guy and far from good looking I still manage to have a lot of fun talking and playing with her. This is my first; I will get naughtier with descriptions in next letter. Cheers.
