Several years ago I made a mistake that I have never told anyone about. I had been married to my wife about two years when thi shappened. We live in the country and because of this we were the last people on earth to get internet. I was home alone one afternoon clicking away on the net when I ran across a site that listed loacl people who wanted to chat or other things. I visited the site and made a friend almost right away. She was a great deal older than I was and married also. We chatted for sometime before the sessions turned to sexual situations. One of our conversations had gotten quiet explicit and she asked me if I was hard. Of course I was so I told her yes. She told me she had been wearing her little butterfly vibrator and was close to cumming herself. That was when things changed. She asked if she could call me on the phone and talk to me. We only lived about 15 miles apart but as far as I knew I had never met or seen her. I told her my number, got off line and in just a minute she called. I was nervous but after she brought her vibrator back into the conversation I forgot all about my nerves. She asked me if I had ever masturbated while someone watched or listened. At the time I had always tried to keep my jerk off sessions private so I told her no. She asked me if I would let her lieten to me play with my cock and as hard as I was from listening to her I couldn't say no. I went into my bedroom and laid down on the bed. I took my cock out and began rubbing it for her. She wanted me to tell her how it felt and what I was doing. As I told her I could hear her moaning under her breath. After a minute she said she wanted to hear me stroking my cock so I put the phone down by my dick and kept stroking. this went on for a couple of minutes before I ask her how she liked it and she said she could hardly hear anything and asked id I had and lube. I grabbed some lotion and squirted some on my hand and started stroking my dick with the phone down there again. I asked again how it sounded and she was moaning like crazy and said she was cumming. I started stroking myself faster and faster and was moaning with her until I came hard. We did this a few more times before she asked if we could meet one afternoon. My wife was at work but I couldn't invite her to our hpuse becaus of neighbors. We agreed to meet at a local park. I grabbed a quick shower and rubbed one out before heading off to meet her. I got there first and when she pulled up she was in a big Chevy van. I got into the van with her and we headed off to a more private place by some trees. She stopped her van and turned toward me and jokingly said "alright, drop em'. I started to pull my shorts off but she stopped me. She said she was joking and didn't expect I would be so quick to comply. We talked for a while before she asked for a kiss. I leant in and gave her a quick peck and copped a feel of her big old titties. She had amazing nipples and I was hard almost instantly. We moved to the middle row seats and I took her shirt off. Her tits were obviously droopy but I didn't care one bit. I went to work sucking and biting her nipples while she rubbed my hard cock. She had her hand up the leg of my shorts squeezing my dick and rubbing my balls like crazy. I told her to get on her knees so I could fuck her but there wasn't enough room in the van. We tried it several ways before giving up on fucking. So instead she pushed me back against the door and took my dick in her mouth. This lady was a master at dick sucking. This was why I rubbed one out before showering earlier. i wanted to last as long as possible. She would suck my cock for a while then she would take my balls in her mouth and suck them. I was in heaven. She let me fuck her tits a couple of times before taking my cock deep in her throat and sucking me until I came. She didn't lose a drop. That was the best bj I had ever had and I still remember those big sagging titties to this day.
