In a clinical setting, a femdom mistress demonstrates her power over a newly acquired slave. She presents him with a chastity belt, explaining its purpose and the rules of his new existence. The man, nervous yet excited, allows her to secure the device around his waist, trapping his cock in a state of perpetual arousal. The mistress then proceeds to humiliate and tease him, making him aware of his new reality. She films his reactions, narrating her plans for his training and the clips she'll create to document his transformation into her perfect, obedient slave.
