How to put your posts under specific pages?

I’ve had WordPress for quite some time now, but it was a very basic blog. Now I am setting it up like an actual site that has pages and such. I would like to know how to post my stories under specific pages.

If you look on my site, you will see some of the posts that I already had. I was trying to section them, where they will be able to be viewed from both the homepage and the page where the post should be sectioned.

Am I missing a step somewhere?
