A muscular, hairy-chested man, naked except for his jockstrap, lies on his back, his massive balls resting on a pillow. Another man, wearing only a harness, straddles him, his eyes locked onto the vulnerable orbs. He begins to apply pressure, first with his knees, then his feet, grinding and stomping with increasing intensity. The bottom man grimaces in pleasure-pain, his cock rock-hard, as his sensitive balls are crushed and manipulated.
