url masking

Hi i currently have four domain names with godaddy and all domain names are in one hosting plan and all domain names land/direct to one website. when the user goes to the website for any domain name they enter or click on, in browser’s address bar they see https://www.first-domain.com but i want them to see the https://www.second-domain.com. i also have the third and the fourth domain as well, but i all i want to change is that user would see the second-domain.com from any address domain they come with.
any suggestions?
