In the dim light of the closet, Michelle's gaze falls upon her brother's thick, uncut cock, straining against his pants. She swallows hard, her pussy throbbing with an unfamiliar ache. She knows it's wrong, but she can't help but imagine what it would feel like to have him inside her, filling her up completely. Her brother, equally aroused, tries to hold back, but the sight of Michelle's heaving chest and the scent of her arousal is too much to bear. They both know they're about to cross a line, but they can't stop themselves.
