In the quiet of their shared home, a sister and brother find themselves alone and restless. Their pent-up frustrations lead them to their respective rooms, where they begin to touch themselves, their desires building. The sister, Michelle, fingers her wet slit, her moans barely contained, while her brother strokes his thick, hard cock. Their secret moments are interrupted when he bursts into the bathroom, catching her mid-act. They argue, but their pent-up lust is impossible to ignore. Soon, they're naked, their bodies pressed together, Michelle's hand guiding her brother's cock into her eager pussy.
