A slave, bound and at the mercy of her dominant mistress, is forced into a rough, gagging blowjob. Her mouth stretches wide to accommodate the thick, veiny cock as it mercilessly pounds in and out. Tears stream down her face, saliva dripping from her chin, but she dares not disobey. The mistress, cruel and unyielding, grips her hair tightly, fucking her face with increasing ferocity. The slave's gagging sounds fill the room, her struggles futile against the relentless onslaught. The mistress finally pulls out, aiming her cock at the slave's face, ready to paint it with her hot, sticky cum.
