This is how foids look like now in their late teens/early 20s. 20s is the new 30s because having a lot of sex early makes you this way, I made a thread about this recently:

I think it has to do something with their bodies thinking since they are already having sex at early age, it must develop faster in order to be ready to take care of children. Of course they are not fucking to have children but their bodies don't know it. It's like young girls taking care of their baby siblings when their mother is drunk or doesn't take care of them all the time, they too tend to mature very quickly (looks wise) because that's the nature way of protecting the baby. These are just my theories but I am pretty sure they are correct.
