The blonde step-sister, left home alone, sees this as an opportunity to explore her taboo fantasies. She strips naked, her eyes locked on her reflection, admiring her full, round breasts and the curve of her ass. Her fingers find their way to her wet, aching pussy, rubbing and teasing her clit. She's so lost in her pleasure that she doesn't hear her stepbrother come in. Caught in the act, she freezes, her eyes meeting his in the mirror. He's hard, his cock straining against his jeans, and she can't help but lick her lips at the sight. She turns, facing him, her body still trembling with need. 'Fuck me,' she whispers, her voice laced with hunger and desperation. 'Fuck me like you've always wanted to.'
