The sister's moans fill the room as her brother's fingers find her clit, rubbing it in tight circles. He's never touched a woman like this before, but his body knows what to do. She guides his cock to her entrance, and they both freeze, on the precipice of no return. Then, with a shared glance of understanding, they push forward, their bodies joining in a dance as old as time, their voices filling the night with their shared ecstasy.
