This is not an underrated game. What happens is that it has a very hot wife who is being fucked by other people who are not the mc. And yes, it is with the consent of the MC and all that is optional. But without going into whether it is unfair or not, this game model does not have many followers. If the MC were her, it could be more successful, but without getting into controversy when the MC is the man and she fucks with others, the game loses much esteem
in addition that people see the trajectory that the game follows by others that are similar. And just as she already fucks without condom, she will gain more confidence and end up fucking behind the back of the mc, dp, etc. And those expectations that surely will appeal to several, are those that reduce the group of possible followers. Is a good game? Maybe but it has that drawback to be able to grow in followers
