Preflop is fine.

Check/Fold the flop. You really only want to see a 6 on the turn and paying 1/4 to 1/5 to see one is certainly -EV. If you believe everyone is weak and will likely fold, you could go for a bluff check/raise and try to represent K-K-x-x. At least this way you stand a better chance of winning than simply calling OOP. If you meet any resistance though, you are likely go to have to give up on the turn.

As played, check/fold the turn. You have bottom two pair with a straight on the board facing a pot sized bet OOP and terrible redraw prospects. Fold, Fold, Fold.

The reason this hand should be bugging you is because you played it poorly after the flop. Learn and move on.

If you are going to take a card off, it is generally much better to do so in position than out of position. You could have fired the turn as a bluff that you had made the straight, but with 3 to act behind you, this is going to be extremely foolish most of the time.
