Two Mormon missionaries, fresh-faced and innocent, find themselves alone in the mission home, their pious resolve tested by the heat of the day. They begin to confess their secret desires, their voices hushed, hands trembling. One reaches out, touching the other's cheek, then tentatively pressing their lips together. They undress each other slowly, revealing young, untouched bodies. They lie down in the missionary position, but their intentions are far from holy. Fingers explore, finding wetness and moans. They lick and kiss, learning each other's bodies, their breaths coming in short gasps. They're interrupted by a knock at the door, forcing them to quickly dress and compose themselves, their hearts pounding with the thrill of their forbidden encounter.
