Looking for a specific fic

[blue_jack]

I'm trying to find a fic I read a while back. It's a get-together story. Jim and Blair go skydiving in order to get Blair more used to it. Jim's friend and his friend's wife are the owners of the place they go to. One thing I remember is that the last time Blair had gone there, it'd been with his previous boyfriend, which is how Jim finds out that Blair is bi. Said ex-boyfriend is a jerk and had apparently scared Blair on purpose, because Blair was wild in the sack afterwards. Does this sound familiar to anyone? Thanks in advance!
