Under the watchful gaze of the moon, a deviant mistress unleashes her inner sadist on her helpless sub's balls. She starts slow, caressing and squeezing his testicles, feeling their weight and warmth. But her appetite for pain grows, and she soon graduates to more intense torments. She clamps, twists, and pulls at his sensitive orbs, making him yelp and squirm. The cool night air does little to soothe his burning, punished balls, as she continues her relentless, outdoor ball bashing.
