Mistress Nina in Pleasure with a little pain

Finally the best part comes for the slave, he can feel Mistress Nina’s perfect fingers around his already half erect cock. His body is pulsing from the heat, everything becomes blurry when Nina touches him between his legs with her skilled, strong fingers. She slowly, but firmly massages him towards his orgasm and when she finally lets him have his release, she smiles mischievously and starts to torment his sensitive member with her fingernails for a little while.
