Elite dominatrix Mistress Ruby Marks is a true handjob expert – though it only works on big dicks. Experience for yourself the most amazing handjob technique you'll ever see! She twists, strokes, pulls, turns, spits and massages with both hands in this insane orgasmic experience. But this wouldn't be Simon Crow – and Miss Marks wouldn't be a domina – without some cruelty, so she also gives it a few good hard slaps, and ends it all with a harsh ruined orgasm.
