Prompt: Finn is in a situation where he needs a last name (maybe he's undercover? Trying to buy a ticket? idk) and acting on his first instinct he blurts out "Dameron". When Poe finds out, Finn wants to apologise but Poe just smirks and says "Keep it. It suits you." https://tfa-kink.dreamwidth.org/1082.html?thread=71482#cmt71482
