Finn discovers he loves being on the giving end of a biting kink several parsecs wide. It's not something Poe ever tried before, or particularly thinks he might be into, but he's open to try for Finn. Does it work for them both? Is Poe actually not at all into it/does it turn out it's on his 'absolutely not' list? Do they end up compromising? What ground rules do they set for eachother?
