A group of religiously bound siblings find themselves in a closet, their virtue tested as they're ordered to service each other's bodies. The eldest sister, a virgin, hesitates before taking her younger brother's massive cock in her hands, feeling it twitch with lust. The others watch, entranced, as she slowly sinks down, her tight, untouched pussy rubbing along his length. The room fills with the sounds of wet flesh and ragged breaths as they all succumb to their taboo desires.
