Gagged and trussed, the submissive writhes on the cold stone floor, their eyes pleading as Berthamorin1995 teases them with a feather tickler. The dominant figure, a master of their craft, knows just where to touch, how hard to press, to elicit a desperate plea for release. The sub's body is a battlefield of desire, their muscles taut, breath ragged, as they fight the urge to beg for more, to offer themselves completely to their tormentor.
