The sub, locked in a state of perpetual, maddening arousal, is made to watch as his mistress teases him with various toys - vibrators, dildos, even a realistic silicone pussy, all within his reach but forever out of grasp. She sits atop him, grinding her crotch against his, feeling the hard bulge of his trapped erection through the thin material of her skirt. His muffled moans of frustration and desire fill the room as she continues to torment him, his release always just out of reach, his chastity device remaining firmly locked, his fate sealed in her sadistic, loving hands.
