Cold-Call 99 in MP3- weak post flop?

[NobodysFreak]

Villian is new to the table so I don't have any definitive reads. As for the players behind me, they're loose pre-flop and have been cold-calling many raises so my cold-call was in the spirit of bringing them along.

This is where I have a problem. Granted, Villain can have any two cards here, but with no reads, I'm giving him something like JJ-AA, and high cards. He called my flop bet which can mean just about anything, but lately it means over pair to the flop and/or set.

Turn: (3.75 BB) 3[img]/images/graemlins/club.gif[/img] [color=#0000FF](2 players)</font>
UTG checks, Hero checks.

River: (3.75 BB) T[img]/images/graemlins/diamond.gif[/img] [color=#0000FF](2 players)</font>
UTG checks, Hero checks.

Final Pot: 3.75 BB

Anyone bet the turn or river? What if I get c/r? Would you call down or fold if no over cards came?
