Nat and bryn are SICK in the head

They work in tandem with sturdymin, kosaki and others in the grooming of 13 yo girls

They think it's fun

Why do they think it's fun?

Because they've been groomed by pedros to see it that way, and ultimately its in their hearts to become groomers themselves 

A normal girl would not be susceptible to sturdymin's lies

But nat and bryn aren't normal 

They came out fucked in the head

They have two personalities - the innocent good girl who's done nothing wrong and would never tell a lie...

And a conniving wench without morals who's mission is to destroy the lives of truly innocent people. They don't care who they hurt, just as long as they get their way and their parents don't find out
