Well I am not giving any spoilers, I just said, no sex with the main girls....That's the thing, it doesn't have to be the main girls. The slow corruption on them is fine, it should be that way. Use the side characters to take that place, fuck even add more side characters. It would be great if you bring in a Patreon voted character for a scene every build for just one sex scene. Whether its you going exploring for whatever reason, maybe you need a resource, or you just want to, and you end up walking up to a girl taking a bath in a river. Maybe you stumble upon a ritual going on and a man is needed to complete the ritual, or you stumble upon a student doing something they shouldn't so you blackmail them for a quickie. The possibilities are endless. Don't rush the main girls for content, even if it has dragged a lot.
But maybe I don't need to set the expectations low, everyone here has lived it
