Bound and at the mercy of her mistress, the serf's body is a canvas of pain and pleasure. She teases him, pinching his nipples and slapping his face, before shoving her cock down his throat. He struggles to take it, but she's relentless, fucking his mouth with abandon. She can feel his eager cock straining against his bonds, craving release. She pulls out, leaving him panting, before pushing him onto his back and impaling his pussy, fucking him hard until he's crying out in ecstasy.
