Many years ago, I was staying at my Grandmothers for the night while my parents were out at a 'dinner/dance'.....I woke up in the night and went to her room for a cuddle, and accidentally saw her doing this.....she had a long, white plastic thing that I learned was a vibrator, and she was laying on her back with her nightdress pulled up and her thighs apart, with her slightly saggy but wonderful looking breasts pulled out over it.....she was around 60ish at the time, but I remember how wonderful her body looked to me as a young lad....
