Riley Reign leads a pack of dominant mistresses, including Venus Vixen, in a brutal ball-busting session. The male slave, Everest, is caged and at their mercy. The girls, clad in sky-high heels, take turns kicking his vulnerable balls, their long, toned legs delivering precise, powerful blows. The slave's cries of pain only fuel the mistresses' sadistic pleasure, as they continue their merciless onslaught, training him to endure their brutal dominance.
