KK early 11+1; flop turn line?

[emeraldice]

11+1 turbo, BB 40. I raise UTG+2 w/ KK.Stacks both ~1500.
Button calls. No reads at this point, button hasn't played the first few hands.
Flop QQ4,I should be lead/folding to raise here?
I check, he insta bets almost pot. I call.
Turn 6, putting flush draw on board. I check, he bets pot again, I move in for a little more than his bet.

How bad is my line vs a typical 11+1 turbo donk, and should default be bet/fold or bet/call on flop? Assuming my limited reads.
