50nl- Middle set facing some flop heat

[Illfavor]

Post fail. Pls move to FR forum.

Both villains are unknown, first orbit. Questions about ranges, esp. when MP2 ships the flop. Seems like they both have sets+combo draws with MP1 occasionally having TT-QQ? Obv never a fold but MP2's play intrigued me as to whether it's more likely to be a draw or a nut hand? Flop bet should be bigger.

**I'm not sure why it says I'm the BB, when I'm UTG.

Full Tilt No-Limit Hold'em, $0.50 BB (7 handed) - Full-Tilt Converter Tool from FlopTurnRiver.com

Button ($17)
SB ($44.65)
Hero (BB) ($50)
UTG ($24.50)
MP1 ($50.75)
MP2 ($59.70)
CO ($53.30)

Preflop: Hero is BB with 8, 8
Hero bets $1.75, 1 fold, MP1 calls $1.75, MP2 calls $1.75, CO calls $1.75, 1 fold, SB calls $1.25

Flop: ($9) 9, 8, 2 (5 players)
SB checks, Hero bets $6, MP1 raises to $17, MP2 raises to $57.95 (All-In), 2 folds, Hero's like lol wat?
