KK overpair but really hard decision on especially turn

[Erik W]

Opponent is 17/9/2.5

Should I call down from the turn?
It seems to me that the flop action and the turn card really leaves me no chance to win.

Preflop and flop actions says me that it is unlikely he has the flush. He probably have JJ,QQ,AA after this actionsequence and all those hands beats me. He can sit
on a KK too but since I have the others it is very unlikely.
AKs is not unlikelly either but after flop he definately hit his flush on turn in that case. I can't see him play another color AKs that way.

I called down but I doubt I should have.
Would you call him down?
Would you have played it another way?

I am SB
