My older girlfriend

I was outside of the barn taking a leak. An older lady walked up and watched me. She was about 30 or forty, she told me to finish peeing which I did. I was 11 or 12. I was going to zip up my pants and she said no lets go into the barn. We walked up to a bale of hay and she had her hand on my dick playing with it and getting it hard. She dropped her pants and laid back on the hay. I dropped my pants and she grabbed it and put it between her legs. It slid in nice and felt great. This sure beats jacking off. She told me to finish in her which I did. She said she wanted more in a couple of days and I agreed. This went on for month’s and I noticed that my balls started looking like a bulls by getting big and my Dick was also getting bigger. I was even able to hit the bottom of her with thrusts and she would yell and moan. This suddenly stopped and I never saw her again. Then my step sister and I (another story) were sleeping together as the house was small and we shared the same bed whenever we had out of town family come by. No way could I get it in her, she was too small
