A tense power dynamic unfolds as a stern mistress takes command of her submissive, bound by a chastity device. She teases him mercilessly, her delicate fingers tracing the outline of his throbbing cock through the lock. His breath hitches as she finally releases him, her hand wrapping around his aching shaft. She strokes him expertly, her pace increasing as he struggles to hold back his orgasm. "Not yet," she commands, her voice laced with dominance. The game of denial and pleasure continues until she decides his release.
