In a dimly lit, kinky dungeon, a bound male is presented to his femdom mistress, his cock already straining against his abdomen. She runs her fingers over the chastity device, taunting him with the promise of denial. She locks it cruelly, then orders him to his knees, presenting his caged cock to her. She grinds her pussy against it, laughing at his futile attempts to hump her, before leaving him bound and desperate, his cock aching for release that will never come.
