Something goes wrong on a mission, and Nicky gets brutally raped. He heals from the wounds and whoever took him removed and destroyed his comms device, so none of the team know it happened. He tries to keep it a secret (reason is up to the author, maybe he's ashamed of not being able to fight the person/people off), but he starts flinching when someone touches him and he hasn't been intimate with Joe, giving all sorts of excuses.

Give me all of the comfort when Joe finds out, and the two of them carefully navigating their first time together after the rape. Bottom!Nicky, please.
