Role of the cum shot

I found very nice topic in the wiki. Its here: The cum shot adds a sense of realism to a staged sexual act, because unlike other aspects of the pornographic depiction, such as facial expressions or dialogue, it is a physiological response and therefore it is difficult to faked without prosthetics and special effects. The ejaculation scene also performs a closure role in the simple narrative form of pornography. When the cum shot is from masturbatory pornography, the semen can be directed at several places, some of which may not even be on the body. Bodily destinations can include the abdomen, the face/shoulders (should the semen shoot far enough), the legs, or even the mouth through autofellatio. Locations beyond the body are usually predetermined sets, including wall mirrors, glass tables (for the camera to shoot under) and black table cloths. Its really funny :-)
