$15-30 monster pot with AKs

[piguy24]

Very loose $15-30 at Bellagio today. I'm in BB with A [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/club.gif[/img]. UTG and UTG+1 limp, UTG+2 raises, MP1 calls, CO calls, button calls, SB calls, I 3-bet, UTG calls, UTG+2 folds, UTG+2 4-bets, all call, I cap, all call.
7 see the flop for 36 SB.
Flop: A [img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/spade.gif[/img]3 [img]/images/graemlins/spade.gif[/img]. Damnit...
I bet out to see where I'm at. UTG+1 calls, UTG+2 calls reluctantly, MP1 calls reluctantly, all others fold.
4 to the turn for 40 SB.
Turn 3 [img]/images/graemlins/diamond.gif[/img].
Now what? I have a strong feeling I'm still ahead here, as I'm pretty sure any flush would have raised the flop. Should I just bet out to make any draws pay or try a check-raise to possibly take out something like a lone 2 [img]/images/graemlins/spade.gif[/img]?
