There are regular porn stars and then there are porn super stars, Allanah Starr is a super model woman and knows how to get the job done when it comes to entertainment. Do you know how long it takes a young girl to grow into her body? It takes long enough to know that after her breasts grow in that men will be attracted to them. Think of it this way, when a life is dedicated to absorbing the benefits of men's attention, then the girl will do everything she can to garnish that attention.
Allanah Starr craved to be loved so much that when she was put in front of the camera she couldn't resist but to take it all off, she didn't complain or act shy, but rather stripped naked and started doing the porn. Anal, from the front or from the back, either way didn't matter to her as long as the sex was good. You think when naked women get nude by taking their cloths off and then taking the dick in that it's a tough job? It's not, if they are professional girls who have been doing this for years they are used to it.
Think of it this way, many girls come to the show to watch others doing their performance so that they can learn the skill and one day be exotic dancers like them. One move, one grind, one twerk away from being the newest model to take the runway. Will you support or will you be upset with all the nudity?
