Two Mormon missionaries, bound by their sacred vows and secret desires, find themselves alone in a cabin, their jealousy over their boyfriend boiling over. They tentatively approach each other, their religious beliefs warring with their carnal needs. A hesitant kiss leads to more, their hands exploring each other's bodies, discovering the firmness of muscle and the softness of skin. They drop to their knees, taking each other's cocks into their mouths, their inexperience making their eagerness more evident. They switch roles, one missionary fucking the other with slow, deliberate thrusts, his hips moving in a rhythm that's both familiar and forbidden. Their bodies slick with sweat, they cum together, their moans echoing through the cabin as they mark their bodies with their shared sin.
