Oh my were the only words out of my nanas mouth when she walked in on me jerking off one morning. Later that day when we spoke about it she explained that she had not been with a man since gramps passed. And she had never seen such a big cock. I was clueless as at 18 I had never been with a woman let alone knew what was considered big for a cock. Well nana changed all that as she took in hand and taught me how to love a woman properly. She took me in her…her mouth and her pussy. Nana was sexy like Diane here.
