It looks like this will be the case, because now other characters and Anne herself started talking about falling in love, or wanting Anne for themselves, even if you're on the good relationship path. Walker is the same as Ryan's cheat path, but this time Anne is cheating even with high relationship points.
I feel like it would be a little awkward to go back. It was already awkward after the first vacation, where Anne opened the flood gates and then closed them again back home with some lazy reasoning to keep the normal progression going.
I think the story of this game is doomed. The sex scenes currently aren't exciting, because they lack context But Anne has already done it all, so even if she gets reigned in she can never do anything "adventurous" anymore, compared to what she's already done.
I'd say finish this game and start over with new characters. Anne looks could use an update anyway imo. She looks kinda oldschool.
I like Anne's image, that walk at the start screen and the way her bum and boob's jiggle do it for me although maybe a little skinny to be perfection and possibly longer hair. But what I find attractive and what others find attractive wont be the same so I don't thin a developer can ever win with the looks of the models he choose for a game
I kind of agree with you about closing the game and start a new though. However I don't think the game is totally doomed just yet. There is a couple of possible outcomes IMO.
1. The Mc finally grows a back bone and heads home early and when Anne returns she realises she has gone too far and is remorseful. They agree that she can still have her fun but Mc has to be fully aware of what is or has gone on... No More secrets.
2. Anne becomes a total bitch and starts to dominate and turn the Mc into a sissy sub where she forces him wear a chastity device and she either make him watch every guy that she so desires to fuck and makes the MC perform clean up duties or she comes home and tells the mc how many dicks she has fucked that day and he has to perform cleanup duties also whist at home dresses him as a sissy maid where he does all the house work ect ect and if he has been a good boy she rewards him with sex every so often. However I dont think there would be much more of a storey to tell after this.
3. They carry on as they are I.e Anne still fucks who she wants, Mc fucks who he wants and become more like flat mates rather than a married couple ( but this sort of defeats the title of the game)
4. They do split up and the storey continues With the Mc and a new partner. Maybe occasionally bumping into Anne.
Out of these options my preferred option would be number 1
