The 4 boys are so into their conversational banter and so aware of one another, that they can't possibly focus on the lady or on fucking her. The first two make a real job out of it, obviously tiring themselves out, pumping away. Not a lot of fun. They have no competence and no style at all; hideously inadequate. I kept wondering how the virgin younger brother would do after the 3 larger losers, but, guess what, he never even tries. Maybe by this time the other softies had given him such a deplorable example of sex that he went back to collecting baseball cards.
