Carmen Rivera, the reigning mistress of hardcore femdom, unleashes her sadistic side in this unforgiving fisting marathon. She commands her bound sub to present her ass, then begins mercilessly pounding her pussy with a massive dildo. The sub squirms and moans, but Carmen isn't satisfied until she's fisting her roughly, knuckles deep. She spanks her sub's reddening ass, leaving handprints, before switching to a strapon for more relentless pussy pounding.
