Seeing a wild sexual encounter is great and gives the nice view of the performers' bodies, but the close up shots are even more arousable. While not offering anything but the one or more private parts all over the screen, that is exactly where their charm lays in. Seeing a close up shot of the wild fucking is similar to putting one's hand on the entrance of the hole and feeling the cock go in and out, just like feeling it with the aforementioned body parts is not enough. The close up shots offer the equivalent of that act, just on the screen, and while no touching is possible, they provide the clear view of the sexual act. Also, let's not forget the close up shots of single pussies, or even cocks. Showing every single detail with nothing to hide, only the bravest individuals decide for the close up shots.
