you've never limp called preflop. opponents did this to me twice last night (once in a 9 player STT, with AA, and the other in the stars 45k, with KK). I almost never limp my monster starting hands, because i hate getting outflopped by the 34o limper and I like to have money going in the pot while i am still favorite. I agree that this line is unusual or tricky for KK or QQ, but playing a flush draw this way from someone who you do not have a read on has become too standard in online play. Now that you show his hand, he really donked this up, I make a note on him being a calling station fish.
