That’s usually how it goes, girls who originally got famous for something SFW (either beauty products, gym routines, etc) follow this route if they ever open an OF (Carriejune Bowlby is a massive example of this shit)
They don’t really care (obviously) about the sexual aspect of it all, it’s just an easier way to get money and they usually have a follower base that’s willing to pay anything they charge for mediocre content
Even if you don’t pay that $300 there will be five other simps paying twice as much
