JJ level 1

[45suited]

Is my line bad here? 3rd hand of tourney. $11 PP tourney

UTG (t800) raises to t45
UTG +2(t775) calls t45
Button (Hero) dealt Jc Js calls t45

everyone else folds...

flop Kc Qs 3h (pot t160) UTG bets t35, UTG +2 folds,
Hero raises to t125, UTG calls

Turn 4c (pot t410) UTG checks, Hero checks

River 8s (pot t410) UTG checks, Hero checks

Is my line standard or is the flop raise just chip spewing? I have a hard time folding my hand, even on a scary board like this, in the face of such a weak bet. Doesn't a bet this weak just beg to be raised or am I wrong here? I assume you all agree with checking it down or should I fire again? I think that once my flop raise is called, I have to shut it down.
