A symphony of moans and slurps fill the air as our bound beauty, her body glistening with sweat and desire, takes her mistress's cock as deep as humanly possible. The mistress, loving the struggle, grips her slave's hair, forcing her to take even more. The slave's eyes water, her makeup smearing, but she's in heaven, her pussy throbbing, aching for release. Her mistress, sensing her need, smirks, "Not yet, pet. You'll come when I say so." She continues to piston her hips, fucking her slave's face, leaving her gasping, desperate, and utterly, beautifully used.
