gracious grandmother 

The gracious grandmother (often shortened to GG) is the act of soaking ones hand in water until it becomes wrinkled, and then using the wrinkled hand to masturbate while pretending it is an old woman masturbating you, perhaps even your grandmother.

It's been awhile since I've masturbated, I think I'll give myself a gracious grandmother.
