How do I play this at 2NL without any significant reads?

MP+2: 152 BB (VPIP: 6.25, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 16)
CO: 356.5 BB (VPIP: 29.41, PFR: 20.59, 3Bet Preflop: 0.00, Hands: 35)
BTN: 100 BB (VPIP: 0.00, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 2)
Hero (SB): 103 BB
BB: 83 BB (VPIP: 100.00, PFR: 100.00, 3Bet Preflop: -, Hands: 4)
UTG: 188.5 BB (VPIP: 34.78, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 48)
UTG+1: 65 BB (VPIP: 50.00, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 4)

MP+1: 100 BB (VPIP: 25.00, PFR: 8.33, 3Bet Preflop: 0.00, Hands: 12)

Hero posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has Q Q

fold, UTG+1 calls 1 BB, MP calls 1 BB, MP+1 raises to 2.5 BB, fold, fold, fold, Hero raises to 10.5 BB, BB calls 9.5 BB, UTG+1 calls 9.5 BB, MP calls 9.5 BB, fold

Flop: (44.5 BB, 4 players) T 3 9
Hero checks, BB bets 21 BB, UTG+1 raises to 54.5 BB and is all-in, Hero ?

I'd cBet 50% on flop, BB/UTG1 seem fishy so I'd just go with it

Not c-betting the flop seems a pretty big mistake.

At 2NL, I'm auto-stacking off an overpair in a 3bet pot and living with the results.

I was scared because I was first to act in a 4-handed 3bet pot. Too weak I guess?

Maybe I shouldn't play scared and accept the fact that there are a lot of fish on 2NL. Thanks!

I cbet. As played I shove and live with it. UTG+1 is a shortie. BB is very probably a fish. I'm not saying we mostly win this one but there's a lot of money in the pot already.

Now if these guys were running 16/12, I just fold.
