A bound man kneels before his mistress, her high heels digging into his back, her voice commanding, "Suck, bitch." He obeys, taking her pulsating shaft into his mouth, his tongue swirling around the head, lapping up the pre-cum. She grabs his hair, pulling him closer, forcing him to take her entire length, her hips bucking wildly as she fucks his mouth. He gags, chokes, but she doesn't stop, not until she's satisfied, not until she's painted his face with her hot, sticky cum.
