Riots official stance on Account Sharing

I was born as a part of a conjoined twin lifeform at birth. We have two arms, I have control of the left, my sister has control of the right. I can't play this game by myself, I need her help. I've just been promoted and I'm worried about the new crack-down on account sharing that Riot will get mad. I would really appreciate an official Riot answer to my particular dilemma, every time I submit a ticket Riot support are not helpful. Thank-you all.
