Why do narcissists tell you a huge story that is all a lie?

they will morph themselves into anything they think you want to see them as to extract something from you for themselves Most likely to puff themselves up in your eyes to get the adoration they want or, if they're really nasty pieces of work, to con you to get whatever it is that they want from you. And if they're really twisted, there's always "duping delight" to consider. Psychopathic individuals who are, I believe, narcissistic in the extreme are said to get their jollies just pulling the wool over another person's eyes. Because they have such warped minds.
