I have no reads or stats on the villains other than the fact that I marked them both as a fish some time in the past.

PREFLOP: Hero is BTN with Q9dd. HJ limps 1bb. CO calls 1bb. Hero raises to 6bbs. HJ and CO calls.
FLOP 21bbs: 9c 9s 2s. HJ checks, CO bets (donk) 19,5bbs. Hero calls and HJ folds.
TURN 60bbs: Ts. CO bets 58,25bbs. Hero calls.
RIVER 177bbs: 5d CO shoves for 115,5bbs. Hero????

BOARD: 9c 9s 2s Ts 5d.

How would you play this hand? Is my squeeze preflop too tight versus two confirmed fishes? I was struggling to put CO on a legit bluffing hand here so I folded thinking I could have some better 9s, I could also have some boats and some flushes. But I'm not entirely sure.
