And don't worry, I see you coming with "that's because you only learned about butts so you don't know about tits". That's where you're wrong, know thy enemy and shit. I learned about as much about the breast region as I did with the posterior region. The human body makes it that everything work together, so learning only one part of it would be detrimental anyway. I know more about the ass, but I know the tits very thoroughly, don't even worry about it.
