Am I able to play sims 4 on a different origin account?

My sister just bought Sims 4 and I thought I'd give it a shot. We have the game installed, I was just wondering, if it was possible to play Sims 4, but on my own Origin account? I tried but it's saying a need a product key, which my sister has already entered for her account.

The product key can only be used once. You will have to purchase your own copy to play it on your account.
