Under the dim glow of the nightlight, the brother's eyes follow the tantalizing curve of his sister's body as she stretches languidly in her bed. Unable to control his growing lust, he joins her, their bodies pressing together. She moans softly as his hand slips beneath her panties, his fingers finding her wet, eager slit. He strokes her clit, feeling her body tense and tremble with pleasure. Their kisses become more intense, more demanding, as they give in to the forbidden desire that has been building between them.
