My stepgrandfather pleasured me with his fingers until I reached orgasm

Yesterday, I found myself alone with my stepgrandfather. He's always been a bit of a perv, but I never thought he'd cross the line. To my surprise, he started to pleasure me with his fingers, exploring every inch of my pussy. I was shocked at first, but the sensation was too good to resist. Before I knew it, I was moaning in pleasure as he worked his magic on me. He even tried to fist me, but I wasn't quite ready for that. When he finally made me squirt, I was completely spent. The orgasm was unlike anything I've ever experienced. As I lay there, panting and trying to catch my breath, I realized that it was actually kind of hot. I don't know what possessed him to do it, but I have to admit, it was one of the best experiences of my life.
