The dim light of the moon casts long, dancing shadows on the siblings' entwined bodies. She's on top, her lithe form straddling him, her hips grinding slowly against his. He's lost in the sensation, his hands gripping her ass, pulling her closer. Their lips meet in a fierce, hungry kiss, tongues exploring each other's mouths. She gasps as he reaches between them, his fingers finding her wet, pulsating core. She's soaking, her juices coating his fingers as he plunges them in and out of her tight pussy. He's rock hard, his cock throbbing against her thigh. She breaks the kiss, her eyes meeting his, "I want you inside me. Fuck me, brother. Make me yours."
