In the grim, cold isolation of the military prison, a soldier endures the harsh discipline of the lash. Naked, he's bound to a post, his muscular body trembling as the leather whip cracks against his flesh. Each strike sends a jolt through him, mingling pain with an unexpected, forbidden arousal. His cock hardens despite the circumstances, standing at attention like a good soldier. The whipmaster, a stern woman with a cruel smile, takes note of his growing erection, prolonging his punishment with a sadistic glee.
