Step Mom vs Step Daughter and Their Catfights- Why?

[LittlePrincess]

Why do so many step moms and step daughters cat fight? Usually its over access to the main man and his cash but is there more to it? This pair are clearly rivals over so much and i just wonder how it would end between them

I hate to break it to you, if such a thing ever happens it would just be a normal fight.
Not some form of sexual competition.

Thinking any sort of inter family fighting (beyond brothers/sisters at a push) really happens is Delulu lol
