Bound and gagged, our male submissive tenses as Mistress approaches, strapon already secured. She strokes his hair, whispers filthy promises, then presses the cold head of her dildo against his tight virgin ass. He whimpers, but the gag muffles his protests. She pushes, and he yields, his ass swallowing inch after inch of silicone cock. She begins to pump, using him, claiming him, until he's a whimpering, begging mess, desperate for release.
