Grandpa's Pleasures - Lilly

I had long since retied and was enjoying the quiet life when my son married a woman who had a daughter. I never thought much of it other than she was always close to me. But then, just after her birthday things took a turn that I will remember forever. The younger lady of the house had set her sights on me, I just didn't know it. When her mom and my son got stranded out of town, she decided to stay with me for the weekend. What happened that weekend has become a story of legend with my friends!
