After going through with the Salim Debt branch i was wondering what to make out of it.
Since Salim becomes quite friendly at the end and even offers the MC to work as a manager in one of his clubs it's pretty obvious that the debt isn't put in place as a threatening game over mechanic.
After putting some thoughts into it I'll assume 1 of 3 possible outcomes (or maybe even a given choice which one you like to pick).
1.) MC is only allowed to work at the club when agreeing to chastity, might be a shortcut to the Femdom branch/a requirement for that branch to progress later on, or something completely independent
2.) a femMC build-up story that is later on required to progress in the Salem+femMC branch, or as an alternate start to that branch in case MC knocked out Paul or gave up on Julia
3.) might lead into that Sissification branch that was suggested by Salim early on in the game
All in all, paying the debt locks you basically just out of content.
So, taking care of the debt is only needed when you want to have a no-NTR-run. (or at least a less-NTR-as-possible, since it can't be prevented in the Julia and MC's mother branches, and make sure to not let the wife work in the MC's company)
edit: When taking care of everything by ending branches early that "endangers" the MC's releationships the game's content is surprisingly short.
edit2: Stumbled across the Mike-Sharing branch again and was wondering again how that was ever meant to play out, since Mike is in chastity for years and Jenna only fucks black guys.
I could only think of 2 possibilitieas:
1.) at the end-game after Jenna was tuned back to normal
2.) gets a Femdom branch progress condition, where the wife and Jenna bringing along black guys they've chosen to swap and Mike and the MC just watching their wifes getting fucked.
Well, there might even be a third option further down the Femdom rabbit hole, where Jenna is pegging the MC and the wife does the same to Mike.
Well, there is also always the final option that i'm overthinking everything way too hard to trying find connections for the stories to make sense but it could most likely be the case that these are completely seperated stories with no impact at all to anything that came before.
I guess the best and most recent example would be the wife-company branch.
