If it were a togglable option, like at the beginning of the game you could click a slider to allow NTR or not. Then that would be fine because it appeals to everyone. That way the people that want it can get it, and the people that don't can avoid it. 

For me though, after the point it's discussed with everyone what he's doing (which was the previous update) it's no longer really cheating. Just a harem, not only is everyone aware of each other but they actively encourage MC to go see other people. It's like establishing rules in a relationship right? So that toggle option would basically be like saying, "hey that rule goes both ways." 

Yes while it would be fair for that to be the case without an option, these visual novels are 50% telling a story, and 50% experiencing a fantasy. Most people's fantasy of course is going to be able to sleep around with people they both admire and (if they're not horrible) then at least care about as well. While it's realistic to have a consequence to those actions, it could take away from the enjoyment. Since one of the best parts about harems are the fact there isn't a real consequence to having all those women (or men) around you loving you unconditionally. Add a consequence to that, and my fantasy becomes a little bit too real and might end up making me sad instead. 

So if the creator wanted to add something like that, I wouldn't mind... BUT only if it came in the form of a option, and not something forced for everyone, as for a lot of people (myself included) it would break my personal fantasy that I look for when I play a visual novel.
