ERDM-156 - "Do you want to have sex with your grandma..." 4 hours of a grandmother lusting after her grandson's dick

Both my parents worked, so I've always been an old lady's child. She put a lot of thought into getting her to eat vegetables and made a warm meal for her. Now that I'm an adult, Grandma and Grandpa are good friends, but Grandma has a pretty good body for her age, so maybe if I invited her out...? I wonder what will happen...?
