You con only reach step 31 through the MC uninstalling the app and agreeing to chastity, every other option closes the branch off early. wife-Jenna step 73+ is all about the wife and Jenna are teasing and cucking the MC, so the MC had to agree into getting cucked to not make the conversations seem to be out of order.
edit: tbh, for me the most interesting part, in terms of story revelant conversations, is the path of uninstalling > refuse chastity > set wife free.
But since the game progress is bound to patreon votes this path will most likely never see the light of day.
edit2: the patreon votes are also the major cause why the game will see little to non meaningful story progress. I'll assume the main story is bound to the MC-Jenna branch, which still ends after step 11, and hasn't seen an update in ages. All the other branches can be seen as side-quests, might reveal some interesting info and pleasing certain kinks, but have no real impact on the main story.
