Um... I dunno if this is real. Think about it: the two girls on the floor could be laying on their stomachs with two other girls laying on top of them on their backs from behind and putting their legs over their shoulders. The girl in the middle (sitting) helps block the view from our standpoint of the girls hiding in the back. Look at the girl on the left. Aren't "her" legs a lot more tanned than her arms? (could be hosery, though)

What do y'all think??
