A slave, naked and vulnerable, kneels before her master, hands bound behind her back. Her eyes, filled with defiance, meet his cold gaze as he strokes his rigid cock. "You will learn to serve," he growls, grasping her hair and forcing her head down. She struggles, but his grip is iron. He feeds her his length, inch by inch, until she gags. Then, with a cruel smile, he begins to fuck her mouth, using her like a toy, his hips pumping mercilessly, his balls slapping against her chin.
