Flopped 2 pair in BB against 4 limpers

[Nairb]

Table had been playing fairly tight pre-flop. I had already had A A and K K folded around with a min-raise in EP trying to get some action but post flop had been very agressive. I just checked my option in BB and flopped 2 pair. I checked thinking someone else would bet and I could c/r but it checked around. Villian that went to showdown I have played with a few times and is at 21/18 over about 300 hands. I had put him on A Q or K Q and played accordingly. Please comment on all streets although I feel now in hindsight betting on the flop would have probably been better IMO.
