The mistress, clad in black leather, watches her slave intently as he masturbates, her voice a steady rhythm of commands. "Harder," she growls, her eyes gleaming with sadistic pleasure. As his body tenses, she commands, "On your knees, slave. Taste your cum." He hesitates briefly, then obeys, his tongue tentatively licking his own release from her fingers. She feeds him greedily, her face a mask of dominance, until he's swallowed the last drop, his face glistening with his own juices and her satisfaction.
