Yeah...show me ANY 11 year old girl who could be mistaken for an 18 year old. Honestly.
And since we all know ganging raping an 18 year old is ok....this should work as a defense.
Many moons ago when I was young we had a girl in our church who at 12 looked easily to be 22. Without trying via makeup, etc.
It's not that uncommon as for unknown reasons it appears girls are maturing physically earlier than they used to, on average.
I don't care if she "looked" 40, though.
