TPTK vs. c/r 3-bet?

[DeucesNeverLoses]

7 handed 10/20 live limit game. Game is pretty passive, no real reads on villains. Villain 1 has only played 5-6 hands so far and only hand he's played he just called a PFR w/ AQcc and bet TPTK the whole way. Villain 2 I raised QJ in MP and he called from BB. He check raised a Ah-4s-5s flop with AQss and showed me. Other than that, no real reads.

I am UTG w/ ATo and raise, villain 1 is OTB and calls, BB (villain 2) calls.

T62 flop rainbow.

BB checks, I pause for a second to try and give a physical tell that I hate the flop, then throw $10 in the middle. Villain 1 raises to $20, Villain 2 INSTA 3 bets. Hero?
