I simply explained why it is written "hotwife" instead of "hot wife", that I think that the game lost its way and devolved into boring "wife fucks someone else, 'haha cuck i wont sleep with you', wife fucks someone else, 'haha cuck, i wont do it with you' " and repeat is something I already said earlier *shrug* It's sad, but thats what this is now.
Essentially Hotwifing and Cuckolding are two sides of the same coin. The cuckold hotwives his partner, whereas she cuckolds him. You can't have one without the other. Generally when a man hotwives his partner, he allows her to have sex with other men, from which both partners derive mutual satisfaction. He though, is generally not allowed to have sex with other women. It's all about her receiving pleasure, and him getting off on allowing her to do it. Hotwifing/cuckolding can though have a humiliation element, with the wife belittling her husband, by comparing him unfavorably with her lovers. And whilst this may not be a part of all hotwife/cuckold relationships, it is a recognised sub-category within this lifestyle. And this can extend to the wife witholding penetration completely from her partner, to further belittle him. So I think it's perfectly within the context of this game, to refer to Bella as a hotwife.
It's been very clear from early on, that the game was likely to follow this path, and involve the more extreme elements of hotwifing. What part of the 'humiliation' option didn't you get? That was there long before you could actually use it. So the implication of it being there at all, was that the MC was inevitably going to get badly humiliated, and that generally means being constantly belittled and put in chastity, in these types of scenarios.
Yes, the Dev could have made this into a different kind of hotwifing game. But since he set out his stall early on, that the MC was going to be a classic cuck, who is increasingly humiliated by his wife, why would he do that?
