King Mark, locked in chastity, kneels before his male dom, King Calvin, in a dungeon filled with the sounds of their heavy breathing and the clinking of chains. Calvin, in full leather regalia, commands Mark to perform various degrading acts, from licking his boots to sucking his rock-hard cock. Calvin then introduces a ball stretcher and a series of brutal, yet arousing, ballbusting games, pushing Mark to his limits in this intense, kinky display of male domination.
