They both know Kaz’s quarters aren’t safe, so they don’t typically… fraternize there. Sometimes they’ll sneak into an empty room on the medical platform, or Medic’s own room because he’s Mother Base’s attending physician/chief of staff so he actually gets his own quarters and it’s pretty much their safe place. =D
Kaz totally loves the thrill of possibly getting caught though, so sometimes they’ll fool around in places where they might be found out. BB actually even catches Medic edging a naked Kaz in Kaz’s quarters once, but medic is a smooth motherfucker, keeps a totally straight face and plays it off like Kaz had an embarrassing medical problem and preferred to be seen in the privacy of his own quarters and BB doesn’t even question it. He actually thanks Medic for being so sympathetic to Kaz’s need for discretion and commends him on his impeccable bedside manner, and Kaz nearly explodes from suppressed laughter.
Additionally, because Medic is kind of a savage when he needs to be, any time he’s had to hide at the last minute and listen to BB get a little too rough for comfort with Kaz, or ignoring Kaz’s safeword/no, he later gives BB a run for his money during training sessions, CQCs the living fuck out of him and regularly gives BB the beating of a lifetime when they’re sparring on the beach. BB totally admires having such a competent soldier (He was always the best man we had), has no idea it’s secret revenge, just kinda grunts and takes it when Medic is a little too rough for comfort when patching him up afterwards.
(Kaz regularly jerks off to memories of Medic beating the crap out of BB)
