"Grannies are older people who have seen everything and don't really care if you disapprove. I heard a buzzing coming from grannies bedroom and knocked on her door she shouted out come in. She was laying on the bed legs open eyes closed and using a toy on her fanny. She said can I help you David? I said no, I had heard a noise and wondered if you were ok, she said, yes I am just fine and really enjoying this. Now take your penis out and start masturbating or leave will you, I don't mind which."
