A secret knock at the door reveals a sister's desperate need. The brother, caught off guard, watches as she enters, her eyes wild with hunger. She's been thinking about him, about his cock, about the taboo thrill of incest. She pushes him onto the bed, her hands roaming his body, her breath coming in ragged gasps. He's hard, so hard, and she can't wait to feel him inside her. She climbs onto him, guiding his cock to her entrance, her pussy wet and ready. She sinks down, taking him in, and they both moan, lost in the forbidden pleasure.
