Mistress Linda in her black and white dress and bright red high heels is whipping her slave's back, who is on his hands and knees before him. She doesn't have a good oppinion on his abilities, so she wants to test him and his toughness. Her strokes are hard and merciless and between strokes, she grabs his cock and tries to make it hard, but when she sees that it doesn't work, she trtures his nipples and cock a bit, just to feel better.
