A former neighbour of mine contradicts you. I used to hear her wanking with buzzing sex toys 3 or 4 times a week and occasionally 3 times in a row during one night. She persuaded me to let her tie me up and she spread herself wide open and made me lick her cunt while she held a vibrator to her clitoris, she was 63 years old and wore glossy high cut lace front knickers.
