Who played, tell me what type of MC is here - a dumb stereotypical cuckold with a micro dick, or a regular guy with an equal marriage?
Hah, if the wife is sleeping with anyone else, there is no such thing on F95 as an equal marriage 99.99% of the time. Wife/gf devolves into a cock craving slut and end up preferring someone(s) more than her hubsband/bf in almost all of the games where this occurs.
And unfortunately in that 99.9% the dude ends up being a cuck and sitting back and letting it happen. Same with female protag games, the woman is always a slut it just might take longer for her true colors to come out
Regarding the wife having a psychosis for her behaviors, there is always mediocation and counslling to help resolve that, if she truly wants to change.. If she doesn't get help then she likes being that way and that says a lot about her character and where the MC fits into her world (or doesn't).
