Frustrated and horny, a young woman, Michelle, retreats to her room for a private masturbation session. She strips naked, lying back on her bed, and begins to pleasure herself, her fingers dancing over her slick clit and plunging into her tight pussy. Her stepbrother, overhearing her moans, can't resist the urge to spy on her. As Michelle's fingers pump in and out, she imagines her brother's cock filling her instead. Caught in the act, she's initially embarrassed but soon finds herself inviting him to join her, ready to trade her fingers for his thick, hard cock.
