Drupal - Creating a site tour

This module can do the same: Guidance

For controlling first time, you can use Rules module.

Check out the Guiders-JS module. It is a guide / walk-through for your site's pages. The Guider can show the page parts and give a short explanation about each part's functionality and purpose. This module is for anyone who is looking for a walk-through, guide, intro, or just a sequenced messaging system.

There is also Joyride JQuery for Drupal Site Tours module for Drupal 7 and Drupal 8 ships with Tour module! :)
