Bit of a unorthodox thread title I'm aware, which is also the reason why I couldn't find good stuff on my own.
The idea is that, much like a real life Cuckoo egg, the story is about character Z (son or a third party) that arrives and slow build themselves up as the main of the house.
The more girls (wives, daughters, sisters) the best, the more the character Z is slowly aware of what's happening the better.

Summing up it's replacement story where the PV might a son (Netori route) or a third party (netorare route);

Sorry if it's sounds complicated, but finding something like that is absolutely impossible using search engines from erotica sites.
