Oooh! Two of my favourite kinks here, space and military :D
Luckily I have a few recs to offer - hope you enjoy them.

Don't Shoot The Sacred Symbol (http://stripytights.livejournal.com/46412.html) - by stripytights (NC17, 4K)
Summary: Jared joined Jensen’s contractor outfit after quitting the military and gets substantially more than he bargained for (in space).

Just A Ride (http://ashtraythief.livejournal.com/45120.html) - by ashtraythief (NC17, 2K+)
Summary: Jared just wants to get off the shithole of a planet he’s living on. Jensen offers him a ride.

Not My Stop (http://ashtraythief.livejournal.com/45859.html) - by ashtraythief (NC17, 3K)
Summary: Jared didn't expect much from Jensen when he got a ride from him, but he'll be damned if Jensen's going to throw him off the ship just because they've become more than a strictly business relationship.

Holy shit! Thank you. I've been trying to find something related to these because I just love games 😆
