Do girls usually under 18 get fucked? Cause I feel like if you live in a world where you know your existence past the age of 18 is to a slut, then you would probably start fucking when your going through puberty.

There is no underage fuckery going on in any of the freeuse worlds I write.

Kids spend almost all of their time at nurseries and boarding schools, isolated from adult society or they are isolated from adults in other ways.
