The elder, eyes gleaming with mischief, nods, "It's just you and me against the world, little brother. Might as well enjoy the ride." They begin tentatively, fingers tracing forbidden paths, gasps echoing in the silent room. The elder, a virgin no more, guides her brother's hand, teaching him the rhythm she likes. Their bodies press together, sweat-slicked, as they learn the dance of the damned.
