The twins, their skin glistening like the black jade of their ancestors, begin their dance of temptation. She, a goddess of the delta, takes him, her warrior brother, into her mouth, her tongue circling his thick, uncut cock like a serpent. He, in turn, delves into her, his fingers probing her wetness, his thumb rubbing her clit in rhythm with her eager sucking. Their bodies slick with sweat, they grind together, their lovemaking a sacred rite, a dance as old as the land they come from.
