I started with my sister at the age of 17 and she was 15. She started tickling me and her hands repeatedly went to my cock. Then she stood up and asked if I wanted her to pose like the women in my girlie magazines.
I said yes and I jacked off as she did. When my cock was hard, she came over and mounted it and we fucked till I started to cum and she pulled off and let it shoot all over her face. We fucked several times a week till she was 18 and went to college. We still do it once and a while, ever after 20 yes. we still enjoy it, and do it when we aren’t getting enough from our spouses.
