If only gay men could do that without getting aroused or turning it into an orgy. The same could be said for a handful of lesbians dog piling each other and the same could be said about guys and girls dog piling each other. One can only assume that one of these "straight males" got a little bit hard when they all got "off" of each other. Always be sure to look for the one who's adjusting himself after a straight male dog pile.
