My wife is in her late 50's and she likes me to go down on her and while I am stimulating her clit with my tongue, I am stimulating her G-spot with one finger and also stimulating her nipples and breasts with my other hand. I can feel her G-Spot swell and get harder and larger and when she goes over the edge, I have never timed it, but I will continue to stimulate her for another 20 or thirty seconds before she is tilling me to get in her. I can feel her continuing to contract for many more seconds and then she wants me to cum.
