Villain is 15/5 over 150ish and I haven't really noticed him get out of line

I think flop is pretty standard. I c-bet b/c I still have the best hand a good amount of the time and I need to protect my hand vs his overcards/draws, lower pairs.

I need help with turn/river plan basically

I think his range after his flop call is like Ax's, (discounted 9x's prob) flush draws and sets

Once the board pairs A on the turn I'm not sure how to really play against this range as the draws will just call likely if I bet as well his Ax's (possibly 9x's?) and he may/may-not choose to raise with his full houses.
