Two siblings, a stepbrother and his little stepsister, decide to hop in the shower together. The sister teases him by intentionally blocking the water with her body, and they engage in some flirtatious play. The brother becomes aroused, and before long, he starts to penetrate her from behind. She is initially resistant but eventually gives in to his advances. As they continue to fuck, he warns her not to tell their parents about what's happening. Despite this, she suggests they take things further by having anal sex. Eventually, the sister climaxes while being penetrated anally, and the brother follows suit shortly after. He then cums on the back of her neck, leaving a mess for both of them to clean up.
