I hate those spots, I'm always afraid of sets here...

PF raise is ok, I'd bet a little bit more on the flop, like 19 - 22. I'm not sure if I like your call on the flop. Basically the question is: what do we achieve with calling here? You're not hoping to hit one of your five outs I guess cause you know that if you're behind now, neither an A or a K should help you. Plus by just calling, villain is betting again pretty much every time.
So we have to think about his range now, has he made a set of 6s or 2s, or is he raising with a weaker K like KQ, KJ? There are no draws on the board so we can rule that out.
Another problem is that we are OOP, so it will be extremely tough to see a "cheap" showdown, even if you reraise the flop.
Allright, IMO you have to make your decision here on the flop. Either raising and fold to a shove, or raising and betting out on turn if villain just calls. If you don't want to invest that much money in a TPTK hand folding on the flop would be a little weak but as mentionend, I don't see too much sense in just calling.
