QQ hand

[betgo]

Live 1/2 NL. 3 limpers to me in 5th position. I raise to 12 with QQ. Both blinds cold call and all 3 limper call, making it 6-handed (I probably should have raised more, but I wasn't sure how the table was playing that way.).

Flop comes J88 with a 2-flush. Checked to me. I bet 40 and get one caller in the blinds. Turn is a 6: check/check. River is another 6 making a 3-flush. Villain bets 75. Should I call? Any other comments on how I played this?
