Brazilian teen Novinha, her young face blushing with innocence, finds herself alone and horny in her tiny room. She begins to touch herself, her fingers tracing the edge of her panties, feeling the wetness growing. Her breathing deepens as she imagines a tall, strong man taking her hard and fast. She slips a finger inside, then another, her moans filling the room. Suddenly, she hears a noise and freezes, her heart pounding. It's too late; her brother has caught her in the act. Embarrassed, she quickly covers up, but the sight of her has left him rock hard. They share a heated moment before she decides it's time to teach him a lesson he'll never forget.
