In a clinical setting, a femdom professional sits, her feet elevated, as her submissive slave approaches. She's clad in black, her expression stern, her feet bare and commanding. The slave, eyes downcast, begins at her ankles, reverently kissing, licking, his breath hot on her skin. "Remember, slave," she reminds, "this is about my pleasure, not yours. You'll cum when I say so, and it'll be on my terms." She guides his head, directing him to the sensitive spots, her voice steady, "Now, cover my feet in your cum. Make me feel your obedience, your devotion." The slave nods, eagerly complying, his body tense with anticipation.
