King Mark, eager to test his limits, challenges Calvin to a ball-busting match. In the dungeon's cold, clinical atmosphere, Mark's chastity device is removed, his hard cock throbbing with anticipation. Calvin, grinning sadistically, orders Mark to kneel. With a swift, brutal kick, he targets Mark's balls, making him yelp in agony. The game continues, each kick more intense than the last, as Mark struggles to maintain his composure.
