Okay, so I had no idea it was possible to make a fake butt that big and that shapely, but I guess it depends on what they have to start with, just like boobs, huh?
I've known a couple of girls with asses like that growing up whom I knew were natural, but I didn't know PS had come along enough to duplicate it.
What are the characteristics of a fake butt? Like the tell-tale signs of a ButtAug?
