Don't Ask Don't Tell: Two Soldiers Alone in the Barracks

Military barracks, an American flag on the wall, a spare tire propped in the corner. Both men keep their dog tags on around their necks the whole time. It starts with a kiss, then their mouths take turns working each other over. They fuck bareback and the roles genuinely flip partway through: the one on top ends up on the bottom by the end. It closes on a close-up of penetration, without showing the finish.
