Thanks, Christ.
Okay, here's my explanation for my approach in this game in terms of pacing each route (Might get bored while reading):
I think the best part of a 1guy getting a girl (or girls) path without any ntr or kinks is the slow development or sort of corruption that happens along the way, I personally find most games with this kind of route (specially ones with relationships that are morally wrong) very enjoyable, until the mc has totally got the girl and can do what ever he wants with her. That's when I usually stop playing. It's just a couple's normal sex life. You can find it on pornhub without having to sit for a couple of hours playing a game and picking options. (For example: DMD. It was very enjoyable for me at first, but once they became a couple and the game simply stuck to vanilla only stuff, it was so boring I left it. I only went on playing after that because of the promise of new stuff, like those sharing and bdsm points, but I never got any of that.)
As for the NTR path, building up an ntr relationship slowly is nice, I don't find it obligatory, but it's a plus. And the most significant feature that affects it's pacing is that the relationship is not morally wrong at all, if the relationships are left to default, the characters lived with the mc their whole lives and they shouldn't sexualize each other at all, which can't be said about say, Linda and Blake. Which makes their relationship easier to develop.
