In the dimly lit dungeon, a bound submissive squirms, her mouth filled with a metal bit gag. Her dominant master, a sadistic glint in his eyes, approaches. He trails a leather whip across her quivering lips, then roughly grips her jaw, forcing her mouth open wide. He pushes his fingers in, testing her, before replacing them with his thick, hard cock. He fucks her mouth mercilessly, his pace brutal, using her like a toy. He pulls out, leaving her gasping, before slapping her face, hard. "You'll learn to take my cock, bitch," he growls, his voice dripping with dominance.
