As the sun sets, the siblings can't help but give in to their urges. In the dim light of their room, they strip each other bare, their eyes feasting on what they've only dared to dream of. The brother's hands tremble as he cups his sister's breasts, her nipples hardening at his touch. She gasps, her fingers wrapping around his throbbing cock, stroking it to full hardness. They come together in a passionate embrace, their bodies slick with sweat as they lose themselves in each other, their cries of pleasure echoing through the empty house.
