In a moment of sibling boredom, a young sister and brother find themselves alone, their hormones raging. She retreats to the bathroom, where she begins to touch herself, her fingers exploring her wet folds. Her brother, hearing her soft moans, enters without knocking, catching her in the act. They argue, but the tension between them is palpable. Later, they make up, their desire for each other growing. She watches as he strokes his thick cock, her own hand finding its way back to her pussy. Just as they're about to come together, their moment is interrupted.
