In a BDSM dungeon, a femdom takes control, her target a slave in chastity. She commands him to his knees, his gaze fixed on her powerful form. Unlocking his device, she takes his rock-hard cock in her hand, jerking him off with expert precision. She brings him close to release, only to stop, leaving him begging for more. His humiliation grows as she denies him, over and over, training him in orgasm denial.
