It took me six months, but I finished the fic! Now let us never speak of it again!
It ended up being 3 chapters instead of 2, because someone had a cute request and I rolled with it. Nobody should read it unless they like them as a couple though, since the challenge was to write an adult spin on them.

Gosh that's really true though, I never saw Fez/Jackie/Eric scenes, though you're right that it'd make sense for Eric and Jackie to interact more since if they're dating each other's best friends, that would put them all in the same orbit. Like, why didn't they ever have double dates? That could've been painfully awkward and fun.
