Is it possible to attach 2 domains to domain folders in github pages?

Question

Domain Name System

In the article isizov.ru/kak-dobavit-domen-k-github-pages I read how to link your domain type domain.ru to your repository in github, for example myrepository.github.io.
This is done like this: "CNAME - myrepository.github.io." in the domain.ru domain settings.
Question: can I link 2 of my domains to one repository. For example domain.ru to myrepository.github.io/domain, domain2.ru to myrepository.github.io/domain2
