I imagine that, if one somehow immune to demonic energy but develop protective instinct as her big broter naturally, she can't actively seek sex even when starving.

Of course, eventually she will fall ill, and anyone with knowledge on succubi will tell the man that his lttle sister is starving and may wither to death soon if she doesn't get some mana. That's most likely the point he will give in (hey, she choose to stick with him instead of leaving and find someone else, nobody with heart will lets anyone else do it).
