A tight-lipped slave, bound and gagged, is at the mercy of her mistress' whims. She's forced onto her knees, her arms tied behind her back, as her mistress presents her with a thick, veined dildo. The slave's eyes water as she takes it deep, her gag muffling her moans. The mistress fucks her face roughly, using the dildo like a cock, before flipping her onto her back and spreading her legs. The dildo slides into her wet pussy, filling her as the mistress fucks her hard, leaving her a sobbing, satisfied mess.
