I'm really enjoying this game so far. I haven't played too many ntr games, but in the ones I played, protagonist tends to be oblivious to the ntr until it's too late, while here you're an active enabler of it from the start. Having a quest where you have to go and kill slimes to get materials for condoms you're going to be ntred with is such a great concept. The same goes for leading your girlfriend to the bedrooms they'll have sex in. If someone knows more games with similar themes I'd love to know them.
I tried two different playthroughs so far, one in which you accept to have your girlfriend have sex with moms, and one in which you don't. I haven't seen any ntr in the latter one, is it not present there at all and they're "vanilla" routes? I was hoping you'd be able to find out they're having sex behind your back, but haven't seen anything like that so far.
