Villain is 29/10...no other particular reads

PokerStars No-Limit Hold'em, $0.50 BB (5 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

Button ($45.70)
SB ($30.95)
BB ($45.35)
Hero ($87.65)
MP ($46.75)

Preflop: Hero is UTG with A, A.
Hero raises to $1.5, MP calls $1.50, 1 fold, SB calls $1.25, 1 fold.

Flop: ($5) K, 8, 9 (3 players)
SB checks, Hero bets $3, MP calls $3, SB calls $3.

Turn: ($14) J (3 players)
SB checks, Hero checks, MP bets $10, SB folds, Hero ???

Final Pot: $24

Edit: Is it okay not betting this turn because you're against two opponents on a coordinated board? Or should I fire another and fold to a reraise/shut down on river?
