My Grandfather Sleeps With My Friend Keila

My grandfather has always been a very attractive and charismatic man, even at his age. One day, my friend Keila came to visit, and my grandfather invited her in for a drink in his room. I didn’t think anything of it at first, but then I heard suspicious noises. When I walked in without knocking, I found them having intense sex in bed. Keila was riding my grandfather hard, moaning his name. I was paralyzed, aroused, and confused by the situation.
