They each have their own "Free" ones where you have to pay to view osts.
Then they share their Twins account which is paid access. I don't know if everything inside is included or if there are additional charges for posts inside.
I could see if they wanted a more wholesome account for their younger fans they could use another one, but OnlyFans probably isn't the platform for that.
It is interesting to see how their polls broke down:
Almost the same number of people voted, but Julia had an extra category so it's not 1:1.
Still, overall, more people voted to see Lauren looking dominant than voted for Julia to be dominant.
But more of Lauren's fans want to see her looking submissive than dominant, and more of Julia's fans want to see her looking dominant than submissive.
Again though, they are already posting cosplay and lolli pics of themselves on their knees looking up submissively at your junk. And all of OnlyFans is "findom."
Femdom and feet are the only things they don't really do yet.
