A brother and sister find themselves alone, their eyes lingering on each other's bodies. He's big, black, and ready, while she's curious and eager to explore. They start with tentative touches, her small hand wrapping around his thick shaft, feeling the heat and pulse of his desire. He fingers her tight, wet pussy, stretching her, making her gasp. She takes him in her mouth, gagging on his size, but eager to please. He pounds her hard, her body struggling to take his massive cock, but she can't help asking for more.
