Bottom set, playing scared

[dedenburn]

Live 5/10 game. Pretty sweet loose game, not too aggressive, and only one decent opponent (bb)

Hero is in co with 5 :heart:5 :spade:
2 ep's limp, hero limps, sb completes, bb checks (5sb)

Flop is j :spade:5 :club:9 :club:
sb checks, bb bets, 1 ep limper calls, other folds, hero raises, sb folds, bb and limper call. (11 sb)

Turn is 6 :spade:
bb checks, limper bets, hero calls?, bb calls (8.5bb)

River is 4 :club:
bb checks, limper checks, hero ??????

I'm already pretty sure I should have raised the turn for a couple of reasons, but given a not-so-great river, what's your line here? I'll post results in white below.
