River play with heavy action

[Girchuck]

$5-$10 5-handed.

An aggressive UTG limps, folded to SB who raises,
I am holding 9 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/heart.gif[/img] in the BB, I call.
UTG calls

Flop: 5 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/club.gif[/img]

SB checks, I bet, UTG raises, SB folds, I re-raise, UTG caps, I call

Turn J [img]/images/graemlins/heart.gif[/img] (5 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/club.gif[/img])

I bet, UTG raises, I re-raise, UTG caps, I call.

What is my next move?
