This isn't just a fuck, it's a claiming. The pet, her ass red and raw from the Master's rough hands, moans as he pounds into her. He grabs her hair, pulling her head back, using her body for his pleasure. She cries out, but her cries only spur him on, his thrusts becoming more forceful, more punishing. He fucks her like an animal, his balls slapping against her clit, her juices dripping down her thighs. She's his perra, his toy, and he's going to use her until she's begging for mercy.
