While 53, I had a lady lover who was 47. She had one grown boy, but the birth was by section and her pussy had never been stretched by child birth. I would have to finger her with several fingers and really work on her opening or I could never get inside. Sometimes she had to settle for oral sex only combined with finger massages of her clit and g-spot. I would say that I could get inside only half or less of the times tried, but once inside, the tight fit drove her wild into constant orgasmic state. While her pussy was small and could not always handle it, she could take it all orally and deepthroat it any time. I asked how she could do that and she responded that she had practiced giving blowjobs to dozens of guys and had become very good at it and allowing her throat muscles to relax while deepthroating. She claimed that mine was the largest penis she had deepthroated, but who knows if that was true.
Even if I got my penis inside her vagina, I could not go deeper than about 6 inches or she would have terrible pain, and we would have to stop for a while. I had to be very careful with her. The only position where I could get most of it inside was from behind doing it doggy style, slowly going deep inside her pussy.
