I might have an idea for this (but DEFINITELY don't want to discourage other potential fillers, since I'm crazy busy this month and only flirting with it anyway) but I just wanted to ask, how wedded are you to the idea of the Soldier being initially confused because rape isn't really part of his routine? Is that an integral part of the kink here? (Gorgeous prompt either way!)
