very tough spot with flopped set

[KitCloudkicker]

full 10.

i limp 33 utg. a few more limpers and the blinds check.

flop is K63 all diamonds. SB checks, BB leads. I raise. horrible player cold calls 2. villain 3 bets. for reference, the 3 bettor has:

1) cold called me pf with KK and just called me the whole way on a paired board (I had 66 and thought I was vbetting)

2) had a vpip of at least 80% in the 4 hours or so we've played

3) played a c/c game on all 3 streets on the majority of his hands.

anyway it folds to me. what is my plan?
