Weird action

[Lethe]

15/30 live.

MP1 and MP2 both play too loose but have tighter raising standards preflop, except for the fact that I've seen them both l/rr previously with suited aces, usually commenting something like "lets make it a big one!"

Button is fairly tight and I haven't seen him get involved much.

MP1 limps, MP2 limps, i limp 9s8s, button raises, MP1 calls, MP2 3bets, I call, button calls, MP1 now decides to cap, all call.

Flop: 9h 7s 2s
MP1 checks, MP2 checks, I bet, button raises, MP1 calls, MP2 c/3bets, all call.

Turn: Kh
MP1 checks, MP2 checks, I check, Button checks.

River: 9d

MP1 checks, MP2 bets, I raise, all call.

After the hand I felt like I played this poorly. Capping flop and leading turn if checked to is likely a better line as I'm sure I have a bazillion % equity on the flop. Thoughts?
