I have now played through all the content. Very cool story, thank you for making the game!

I will probably replay and see what changes if I get it on with Christa too. I would have taken a chance to start something up later on (if Foxy gave her blessing), but there was no such path.
On the other hand, the path without Christa but with Amira was apparently a less well tested one. So I went ahead and noted down all misplaced lines I spotted, to hopefully improve the game a bit more.
Christa: No more arrest's or we will both shut up shop.
->wrong on route were nothing sexual with Christa is going on
Jack: (I can't be this weak.)
Jack: (I have to be strong like Jack.)
Jack: (He didn't curl up and cry when he did his first kill.)
->Those lines are by Jessie, not Jack
More lines that make no sense on a route when nothing sexual is going on between Jack and Christa:
Jessie: Think about my other offer too, I already cleared it with Christa
Jessie: She can't fully join Fox Corps if she doesn't join your harem. (Christa is Fox Corps too. Surrounding lines need adjustment as well)
Jessie: Did you know he's only fucked two girls before us!
Jack: You're not, I am a very lucky man, I have three number ones.
Jack: (If Christa hadn't prepared me I would have blown right now!)
