Strategy question in Loose game

[lewdjunglist]

I know this is bad play to start...

This is a loose $1/2 home game. Min buy in is 80, max is 300....but tonight a few bought in for 500. At the time of the hand there are 9 people at the table.

I'm dealt KdKh pre flop in MP. I raise to 25 and get a caller in the SB, who is a LAG but is sometimes more passive. He's a huuuugee gambler though, definitely an action junky. I also get another caller from UTG. This guy is a little loose, but respects my tight play.

So the flop comes 7c4c3d

The action goes check check...and I check because I feel this is in the SB's neighborhood.

Turn is a Qs.
SB bets out $50. UTG folds and I wait trying to get a read on him. I say call and he blind bets $100.

River is a 6h

What do I do? I know there are quite a few leaks here.
