I'm sorry, but I really don't understand why you need two accounts when you can have as many websites as you want on one account. Let us know if you think of a way to explain it. Plus it would be a lot more convenient for you to just need to log in to one account to manage both websites instead of having to log in and out all the time.
Your friend can certainly create his own account if he wants, but if you log in to both accounts you'll run the risk of them both getting suspended.
