Granny masturbating in lingerie is my favorite thing to do with my girls. She is old and proud, but still a horny tease. It takes some time, but as I watch her grow older I am filled with fantasies of what it would be like to be her in adult lingerie. Not sure if she wants to try out the dominatrix costume, but I think she would, or maybe even a French maid type costume, or even a German SS officer costume. The choices are all yours Granny!
