"How is my dick?" echoes in his mind as he looks at his sister, her eyes filled with a hunger he's never seen before. He's been careful to hide his feelings, his growing attraction to her. But today, she's caught him off guard, her question igniting a fire within him. His cock twitches, straining against his pants, betraying his desire. He watches as she notices, her gaze lingering on his bulge, her tongue darting out to wet her lips. The air between them grows thick with tension, their bodies yearning for a connection they've both been denying.
