A submissive, bound in intricate ropework, hangs helplessly as their dominant master approaches, a wicked glint in their eye. The master runs a finger along the sub's lips, pushing it in to silence their whimpering. They grab a riding crop, snapping it against the sub's ass, leaving red welts. The master's sadistic pleasure grows with each strike, their cock straining against their pants. They unzip, revealing their rock-hard dick, and force the sub to take it deep. The sub gags, tears streaming down their face, but the master only fucks them harder, their rough, dominant thrusts pushing the sub to the brink of orgasm.
