Either it's the title of the worst porno ever, or somebody has forgotten the main reason people get married. Surprise: the people who were supposed to wait until marriage to have sex, are having sex while married. The trick hasn't worked: celibate priests have long known that marriage stops the sex drive, so by forcing people to not have sex until marriage, then living a sexless married life, would make the rest of the world as miserable as a celibate priest. Except for those sex-crazed atheists; they fuck like bunnies, don't you know. But, it turns out, married people will have sex anyway, even if their own children are in the house. Those pervs.
