Lady Blackdiamoond stands calmly next to the lounger and looks at the slave, who is restrained with the Segufix. He cannot move, only his breathing quickens as she demonstrates her power. With controlled, precise blows to his cock and balls, she lets him feel that his every movement is under her control. Her gaze remains cold and determined as the slave's cock becomes hard and swollen with arousal. At her mercy, the slubb is used to make him to cum. It is clear to him that at this moment, his mistress alone determines what happens.
