I got good training from my old Neighbor

I'm David 31 and married to Rebecca and we have 2 children 4 & 2, I've away and have just returned to my parent's house. We purchased it from them as they downsized and moving back into the house brought back a lot of memories. When I was 18 almost 19 I was still a virgin and quite shy around girls. My parent's house is on a corner block and so we had only one neighbor Martha 64, widow and I had known her most of my life. She kept to herself a lot and I would see her gardening most days. My parents went away on a second honeymoon they called it I was left home alone my other siblings had already flown the nest so to speak. I was working part-time at the mall and stayed home mostly. Then one day I was sitting in our back yard and Martha came to the fence and asked me if I could remove a stump of a bush she was removing from a garden bed. It was too heavy for her to move. She had dug around it and cut it free and just wanted it placed in the garden rubbish bin. I agreed and went over to move it, it was heavier than it looked. I squatted down with my legs on each side of it and manage to pick it up and at the same time, I heard a ripping sound. My pants had split, but I carried to the bin and was going to return home. But Martha insisted she repair my pants or at least look at them to see if they could be repaired. I went inside her house with her and removed my pants. she gave me a towel to put around my waist over my shorts. I sat opposite her as she looked at the pants and then she said only the seam was split and she would fix it straight away. Turning my pants inside out and then started sewing them on her machine. As I sat waiting for her to finish, my mind started to wander a bit and see photos of her in her younger days dressed in leotards in a dance pose. I started to think she was sexy looking and my cock agreed by going hard as a rock. I was still daydreaming when she told me she was finished, I awoke and stood to put on my repaired pants, not realizing I had a boner and it was sticking out the front of my shorts as I dropped the towel to the floor. I realized it was when I heard Martha say oh my that is a nice one. I was shocked when I realized I had my boner pointing straight Martha. I turned away to try and put it back in my shorts, but Martha wanted me to show it to her fully. I felt awkward and finally agreed and removed my shorts. She asked could she touch it and I just nodded, she started to stroke it and without asking started to suck it. Then she stopped and said we should go to her bed and get more comfortable. She led the way holding to my cock and she had me lay on my back and she went back to sucking my cock. I started to feel my cum rising and told her, she kept sucking and took it all in her mouth and after swallowing it. She asked me would I do her a great favor and fuck her, I was in heaven already after the blow job and agreed. She soon had me hard again and we had sex after she told me to suck her tits and later we fucked again. I became her lover and willing student and taught me a lot about pleasing a woman and even after my parents returned I would go over and fuck Martha. Sadly Martha died in a car 4 years later, but she had taught a great deal. Two years later I met Rebecca a nd 18 months later we married.
