K9s missed flop

i'm posting this because it's a common situation i run into. i have overcards but several callers and i miss the flop. is the way i played this standard? i seem to bet the flop and fold the turn like this not only because on the turn it's more likely a better hand is out, but because the bet doubles as well.

first hand, so no reads yet.
