The other person that you want to be on the mount can not already have a mount equipped. Also, you must be in a group with that person. Hope this helps! ^_^
Can someone tell me how to get another person on a two person mount?
So first, find the person that wants to get on/that you want to get on and click on them. Add them to your group (at the bottom of the character panel) and once they have accepted they can walk up to your mount and press "x" to get on!
