A brother and sister, their bodies aching with unspoken longing, find themselves alone in the confines of their shared bathroom. As the sister, her curves barely concealed by a thin nightgown, fingers her wet slit, her brother enters, his cock already hard and straining against his boxers. Their eyes meet, filled with a mix of fear, desire, and familial affection. They come together, their bodies fitting perfectly, as if made for each other. The sister's cries of pleasure echo off the tiled walls, her orgasm ripping through her as her brother fills her with his hot seed.
