UTG is 50/15/1, Button is 37/15/1.1

I'm lost on every street anymore. I bet the flop, but I know now one's folding. Any draw, overcards, or pair is calling. Seems like the bet is mandatory, but I get no info out of it.

So, I'm at the turn with 2 opponents with Ace high, which seems to be the case much of the time with big aces. Do I lead the turn with ace high into 2 opponents?

They're passive opponents, so I can fold to a raise, but one just calls. Now what on the river? If I lead, what's going to call I still beat? If I check, am I calling a bet?
