If you do add Aurora's POV. You should also make it so she can get 'cuck queened' herself. Maybe one of Aurora's friends or her cousin visits and they try to take Oliver from Aurora. So the stakes are high for both of them.
This could allow Oliver or Aurora more incentive to cheat due to being jealous due to seeing their partner flirty, or catching them in the act. Thus Making it a complete NTR slugfest for either POV. Would give the players a fun choice of cucking either Aurora or Oliver . Could help you make branch plots and much more if you do decide to go dual POV.
Edit 1: Heck later in the game, why not make them realize they both like having other partners and they agree to become swingers or something. Who knows. Endless possiblities here. This could be a path if both cheated on each other or something and come to a heart to heart.
