KK on A high flop vs suspected donkey

Reads: Villain was only at table for about 10 hands but has played 1/2 of those so far. My image doesn't matter to this guy.
Problem: What to do with KK on A high flop especially when donked into & the Ace trips up on turn?
I feel like I'm totally defining my hand strength on the flop. This guy has a ton of aces in his range given my read(loose fish). I feel like I'm getting value town, yet still getting an excellent price to call down after the A trips up on the turn.

Well the turn is a great card for u obviously. I play all the streets the same, no point in raising anywhere and his bets are really small all the way so he priced u into calling.

god im so tempted to raise river as he'll look you up with qx alot, but im sure i'll end getting shown a4 or something, I usually play this the same as you.

i play it the same also vs 3 1/4 pot bets. i think were good 1 in 6 times here surely.

I expect to be good here a lot more than 1/6. I'd play same and expect to win money.

played pretty muc h as good as anyone.
