Bound at the wrists and knees, a trembling submissive awaits his mistress' pleasure. She enters, clad in a corset and thigh-high boots, a leather belt dangling from her fingers. His eyes widen as she orders him to service her, and he eagerly obliges, worshipping her feet before moving up to her glistening pussy. She guides his head, face-fucking him with abandon, her belt leaving red welts on his back as he gagges on her wetness.
