Two naive Mormon teens, sent on a missionary journey, find themselves in a taboo embrace. Alone in their cramped apartment, the redheaded sisters share a secret, forbidden look. One tentatively reaches out, her fingertips grazing the other's cheek. Their breaths hitch as they lean in, lips meeting in a chaste, exploratory kiss. Soon, their hands roam, tracing the curves hidden beneath their modest clothing. They finger each other's wet, untouched pussies, their moans muffled by the missionary hymns they've been taught to sing.
