As the temperature rises, so does the tension between these siblings. The brother's gaze is fixed on his sister's ass, his cock throbbing with desire. She feels his eyes on her, and it sparks something within her. She turns to him, pushing her ass out, and he takes the hint, sliding his cock into her tight asshole. They fuck in the heat, their bodies slapping together, the sound of their moans filling the room. The brother's cock slips out, covered in lube and ass juice, and his sister eagerly takes it into her mouth, sucking him clean.
