30-60 what's your river line?

[PokerPrince]

Decent online game with a few soft spots. Loose utg raises, looser utg+1 coldcalls(any two broadway, any small pair). I 3-bet from sb with AA and both call after bb folds. Three to see a flop.

Flop: K,J,5 rainbow

I bet, utg call, utg+1 raises and I 3-bet. Utg folds and i get called by the loose goose.

Turn: K,J,5,3 rainbow

I bet and get raised. At this point I am almost totally sure I'm up against KJ and need an Ace,5 or 3 to win the hand. This player had been slowplaying small sets all night so I feel if he had 55 he'd wait til the turn to put his first raise in, so KJ seemed the only logical choice.

River: K,J,5,3,3

Ok I hit my money card(or presumed money card). What do you do and why? Remember this player is loose and moderately aggressive.
