I like to imagine that when BB and Kaz get into that naked fistfight in the showers and then end up outside with everyone watching, BB just like CQCs Kaz and forcefully bends him over his knee, holding him down with his hand between his shoulder blades and relentlessly spanks the living fuck out of him in front of all the soldiers until he’s squirming and his ass is tender and bright red, and then when BB finally releases him, he goes to pull his pants back on and is reduced to a cringing, whimpering mess because his ass is so raw. But then later when they’re alone in bed, BB lovingly rubs a cooling cream into his ass and the relief gets Kaz so hard that BB has to jerk him off several times.
Sometime later Kaz realises how much he loved the pain and the humiliation and starts intentionally pissing BB off just to get bent over his knee again. Occasionally BB will use Kaz’s own belt on him and marks up his ass so much that it’s painful for him to sit down and when they’re in the mess hall or wherever, Kaz is squirming uncomfortably in his seat and all the soldiers are trying really hard not to laugh because they know BB regularly spanks the living daylights out of him.
