NL50- KK vs Limp/Raise

[Jeff76]

2nd orbit at this table. 1st orbit we played 6 handed an villain open raised 4 of the hands. I have played one hand so far in which I raise, c-bet, then c/f the turn.

I am NOT folding here, but I'm curious as to thoughts on what my plan should be for the rest of the hand. Should I re-raise here or just call? Also, FWIW I tanked here for a while trying to think about this, so villain might draw some conclusions based on my timing here.
