Felt it now, or see the river ?

Second hand at the table, so no reads.

Monster flop, set of aces + NFD. I thought about check-raising the flop, but after a bet AND a raise, I might as well turn my aces face up. I'm not that vulnerable to straight draws, since the hearts are no good.

What could the villain have here ? Aces up, Lower set, broadway + lower flush draw. 5 makes the wheel possible, but I can't see him raising that board with a wheel draw.

Spring the trap now, or call to see the river ?
