The cramped, metal-framed bunks creak under the weight of the two soldiers as they lie side by side, their bodies turned towards each other. The air is thick with testosterone and the scent of sweat and precum. One, a straight-laced marine, his uniform still on, unzips his fly, his hand wrapping around his stiff cock. The other, a sailor with a reputation for his lustful ways, mirrors his buddy, his hand sliding up and down his own hard shaft. Their eyes meet, and the marine's hand pauses, a moment of hesitation before he resumes stroking, his grip tightening as he watches the sailor's hand move in rhythmic motion.
