I'm surprised people are surprised.
Was there ever a point in time when say the "swinging path" wasn't inextricably tied to heavy bbc/cheating fetish content?
Correct me if I'm wrong, but you can't even get to the part where you message other couples on the app with wife without going through the whole silly anisa/jax charade. That's exactly why I've never liked this game - you can try to play it as an open-world relationship simulator phone game going on adventures with wife, but you soon realize it's not designed for that.
Up to v0.4.6 you could at least get to the Wife+Christina+MC FFM content without the wife ever cheating on the MC.
When with 0.4.7 the route seperation happened i've suggested an "Alpha" tweaking of sharing branch in which everything happens as usual but before MC and wife are meeting up with Anissa and Jax the wife would call it off because she felt guilty for deceiving the MC into it. And giving it another try with the M&F app afterwards with both agreeing to it. If the player isn't interested in sharing the wife with another man you could even skip over the first time with Rae and her BF and go straight to the Wife+Rae+MC threesome when her BF lost interest.
Nearly no additional work be needed to make something like that happen since 95% of the content is already there.
Just need to add a codeline that skips a couple of steps when "NTR off"=true and add a step with a short conversation where the wife calls the meeting off, and maybe a choice for Rae+BF sharing content or skip to the FFM meeting afterwards because Rae's BF got called into work or something like that.
The end of the FFM branch became annoying again when Jenna started to butt in and wanted to turn it into a BBC MMF.
