Adventure. I assume it's been added simply because adventure features in the game title, and not because of the usual reason, because it's an action/adventure type game.

Anyone who has an open relationship, whether he be the most masculine, BBC stud on the planet or not, is sharing his wife or partner with other men or women. That does not make them cuckolds. You simply have no idea what that word means. In this game the MC on certain pathways can become a cuckold, if he chooses to or makes stupid decisions. But he is essentially a voyeur, not a cuckold. Everyone who enjoys watching porn is a voyeur, it doesn't make them into cuckolds

People in porn games don't really have to bother about STD's (unless the Dev includes it in the story), so protection is pretty irrelevant, and bareback sex has no ill consequences ( we can assume his wife is on the pill, since she doesn't want kids). And on certain pathways there is no cheating between husband and wife, because they've both agreed that they can have sex with other people, outside their relationship. However, a low relationship score will make Anne start to behave badly.

Another game where so many comments have the MC erroneously as some kind of pathetic beta cuck. Apparently, by a lot of peoples muddled thinking, if the MC fucks loads of girls behind his wife's back, that makes him an alpha male, and there is nothing wrong with it. But if his wife does the same, then she's either a total whore if she has sex without his knowledge, or he's a complete wimp if he gives her permission to do something he's already done. I don't understand such hypocritical bullshit!

Just choose the other option, it works fine

Making her into a prostitute, would go against the whole premise of the game. It's supposed to be a mutually beneficial experience for both partners, they're trying to save their marriage after all. I can't see Anne agreeing to such an idea, she would definitely leave the MC. And why would he even have such an idea, when his fantasy is sharing his wife, but in a way that maximises her pleasure? Both him and her want to involve other guys, it's you that objects to that, not them.

I managed to get through the whole of Chapter 11, Part 1. It must just be the pathway that you are following.

I agree. The NTR content is only possible if you make certain choices. For instance failing to have sex with her when she asks for it, or telling her she can't have sex with a guy, when you've set it all up, and allowed her to become sexually excited at the prospect. That reduces your relationship score, and if you allow it to get low enough, Anne will start cheating and become a lot more selfish when it comes to joint experiences( this is when true cucking will happen).
