So after the asset comes in from a mission he's usually pretty keyed up - the techs have come up with a way for him to release this pent up tension. They lead him into a room with a sort of padded, rounded bench that he straddles vertically and there's a little hole for him to push his cock into. The asset, once settled in and strapped down, eagerly humps this like a dog until he is satisfied and slumps down on the bench, relaxed.
Bonus for people coming over and petting him, touching his asshole while he's rutting, calling him a good boy, maybe pushing things inside him as an extra reward.
