There is this married blonde and two of her friends that work at an office and latley their brunette boss has been getting off work at 2:45 and is supposed to get off work at 5. So one, day one of the blonde's friends suggest that if their boss leaves early the next day, they should leave five minutes later. So the next day the boss leaves early as they expected, and they leave five minutes after her. The blonde gets home and opens the door to her bedroom quietly to surprise her husband, when she sees her boss and him having sex.
So she slowly closes the door and the next morning she goes to her job and tells her friends "We shouldn't leave early from work anymore, I almost got caught yesterday."
