In the dimly lit dungeon, the slave's chastity device glints under the harsh lights. His mistress, a vision of power in her latex catsuit, orders him to pleasure her without finding his own relief. He hesitates, his cock already painfully hard, but her stern gaze brooks no disobedience. His hands, slick with her juices, stroke her clit, tease her folds, as she watches, her pleasure mounting. But for him, there's only denial, only the torturous pleasure of serving, his orgasm a distant, tantalizing dream.
