How does this poor girl feel when she is tied up in ropes and absolutely helpless right now? She knows that her dominant girlfriend enjoys a lot torturing and humiliating females in bondage and can do any cruel thing to her. She is absolutely right, domina likes all kind of breath control games and she chokes and hand smothers weak roped sub, making her almost lose conscious, while her hand is put over her sexy mouth. After such a brutal treatment, mistress decided to play with that smooth shaved pussy a little and attached vibrating butterfly right to her clit. As dominant females watches preorgasmic convulsion of her girlfriend she gets all excited herself and sits on the face of her female sub ruining her orgasm and making her smother again.  That is really amazing handsmother and lezdom discipline scene!
