The siblings huddle together in the cramped attic, their bodies pressed close for warmth. They've been sent to bed early as punishment, but neither can sleep. The moon casts eerie shadows through the cobweb-covered window, the wind howling outside. The brother, always the curious one, reaches out to touch his sister's face, tracing the line of her jaw. She shivers at his touch, her heart pounding in her chest. He leans in closer, his breath hot on her face. She can feel his desire, his hardness pressing against her thigh. She knows she should push him away, but she can't. She's drawn to him, her body aching for his touch. She reaches out, her hand finding his, guiding it to her breast. He groans, his mouth finding hers, their bodies entwining in a dance as old as time.
