Trapped in a cramped space, the siblings' bodies betray their religious upbringing. Their hands, once used for prayer, now roam, igniting a fire that threatens to consume them. The sister's breath hitches as her brother's fingers trace the outline of her panties, feeling the dampness that betrays her. She gasps, her head falling back as he pushes aside the fabric, his fingers finding her wet, willing center. Their bodies move in a rhythm as old as time, their sins etched into the very air around them.
