In a private BDSM dungeon, a femdom takes control, transforming her sub into a crossdressing sissy. She tightens a collar around his neck, making him kneel and address her as 'Mistress'. She commands him to dress in lace and satin, his massive cock softening as he embraces his new role. She mounts him, riding him reverse cowgirl, his humiliation complete as he's used for her pleasure, his feminization ritual ongoing.
