AKo. Three to the flush on flop

Wow, worst table i've seen in a while. I just joined becuase the stats said that there was 100% players to the flop! In about 10 hands I won 15BB, being called down with monsters like K high (not kidding). Everyone is really loose. About the hand:

I had raised the previous hand with AJ and won at showdown. My biggest question is the flop. I have 4 outs and may even be winning at this point with A high. Do you call given the loosness of this table? Should I have just continuation bet (knowing an K[img]/images/graemlins/club.gif[/img]x and/or A[img]/images/graemlins/club.gif[/img]x will raise me?)
