In the dimly lit room, Marvin, a new recruit, stands naked and vulnerable, awaiting his initiation. His hands tremble slightly as he takes his first tentative strokes, his uncut cock growing stiff under the watchful gaze of the unseen camera. The air is thick with anticipation as he explores his body, his fingers tracing the lines of his muscular torso. He moans softly, his breath hitching as he grips his shaft firmly, his movements becoming more confident as he nears the edge of release. The room echoes with the sound of his wet, slapping strokes, his balls tightening as he approaches his climax.
