"Draco's" enormous cock throbs as his sister, consumed by religious guilt, tentatively takes him into her mouth. She sucks and licks, her hands shaking as she strokes his length. Draco, equally torn, watches as she struggles with her desires, her wetness soaking her panties. She climbs onto him, impaling herself on his thick cock, her tight pussy stretching to accommodate his size. They move together, their bodies slick with sweat and desire, both desperate for release yet haunted by their sinful act.
