In the confines of their shared quarters, the straight soldiers indulge in a forbidden fetish, their big, hard cocks aching for release. They take turns rimming and fingering each other's assholes, preparing the tight holes for their bare dicks. With no regard for consequence, they thrust deeply, their balls slapping against each other's skin. The room echoes with the sound of flesh on flesh, their moans muted only by the fear of discovery. They fuck until their cocks explode, filling each other with hot, sticky cum.
