"You want this, don't you?" He grabs her hand, guiding it to his bulge. She gasps, feeling the heat and size of him. "Yes, brother. I want it." He pushes her to her knees, "Then show me how much you want it, baby sister." She looks up at him, her eyes filled with lust and a touch of fear, then takes him into her mouth, eager to please.
