Teaser Text For Non-Members/Members

I have set up a members-only section for the site where people pay to see exclusive content. I have exclusive content – a celebrity interview in this case. My question is how do I display a portion of the interview with the first 3 – 4 questions for non-members to pique their curiosity?

I do not want to change the length of the teaser/preview globally for all member posts – just for the longer interview posts.
