Mistress Helen was horny and she knew that she did not have anyone to fuck her the way she deserved. And since she did not want to be horny throughout the day, she chose to masturbate. She knew another benefit was that she would be satisfied and would not think about sex until she felt horny again. So she sensuously touched herself and played with her tits and her clit before she fingered herself while rubbing her clit and she had a great orgasm.
