This is a good point. They should save the juciest bits with the MC's closest family until last, let us look forward to it a bit. Meanwhile he can keep developing the paths of the secondary characters, and finish their paths first (maybe have one teasing development per family member each update so there is at least some development for them aswell).Am I the only one who would like more Celia's content? I really like that bitch.Also blackmail feels nostalgic, like good old icstor games.
Icstor could do the side milfs pack - Celia/Neighbor/Judy. Also there's plenty of interesting chicks in high school - Lily/Macy/Delilah. Maybe headmaster?
Linda/Caroline/Sarah should be more like final bosses. Fanservice is cool, but don't overdo it. It can hurt the story line and milfy city got a pretty great plot.
At least that would make the most sense to me if this was a completely new project, but maybe it would be a bit too much of blue-balling since we've already gone quite far with his mom and sisters.
