The brother, unaware of his sister's deviant plans, sits innocently watching TV. Suddenly, she pounces, straddling him and pushing him back against the couch. Her hands are everywhere, unbuckling his pants, freeing his cock. She leans in, her breath hot on his ear, "I'm going to make you feel so good, little brother." She slides down, her mouth engulfing him, her tongue swirling around his tip. She takes him deep, her throat constricting around him, her head moving in a steady rhythm, her moans muffled by his cock. He grabs her hair, guiding her, his hips bucking as he nears his climax, filling her mouth with his hot cum.
