Help displaying posts

Hi there – my apologies for the basic question but I’m very new to WordPress. I’ve installed the WP RSS plug-in to my site at sexbombsburgers.com and I’m trying to get blog posts from my other site at wordsbynowak.com to feed into it. All I’m getting, however, are headlines. I’d like to get a few lines of the text to show up as well. Any help in accomplishing this would be most welcome!
