There are 3 main routes - in the game they are called Harem, NTS and NTR.
1) Harem is essencially a cuckquean route with possibility for the wife to be bisexual or "pure" cuckquean (when wife only watches). Later in this route you are asked if you want to share her with men too and if you want to swing with other couples. There's no content for that yet, but if you answer yes then the certain flags are set to "true", so this content will most certainly be available in the future updates. So this "Harem" route depending on your choices can be a cuckquean, swinger, or stag/vixen route. On either subroutes there's no humiliation, tho there are a few more possible subroutes that I haven't played through yet. You can also cuck a willing cuckold on this route.
2) The "NTS" route consists of two subroutes - cuckold with different variations and "dominant" sharing. The dominant sharing is when you let random guys on the street plow your wife raw in crazy gangbangs with many men. I'd rather call it a "crazy pimp" subroute. On the cuckold subroutes there's a lot of humiliation, much much more than on the NTR route (there's actually very little humiliation on the NTR route except the very fact that the wife cheats).
3) NTR - you most likely aren't interested, so I won't elaborate much. I don't mind light-hearted/humorous NTR, and here it is exactly that, so I enjoyed it, but it leaned too much into BNWO territory in the end so I won't continue it in the future updates.
