I have to admit that even I am shocked at just much I love being a cuckold.
When your wife got the promotion to become her boss's personal assistant, she had to start working late with him several nights each week, and her duties also included going to business dinners with him and accompanying him on business trips. But still, you were oblivious to the obvious signs that their relationship involved more than "just business". Now you realize she probably has been cuckolding you with him for months and they are about to take their relationship to the next level. And part of what makes it all so painful for you is that your wife does not seem to be at all concerned about your feelings.
Everyone knew your wife had just fucked him, when they walked back into the party.
