4 Handed 15-30, How would you play this hand?

[Jeffage]

The game is 4--handed and aggressive on Party. I have As4d in the SB. UTG call, Button calls, I call for one chip (arguments can be made for raising here but these players don't fold, I'm out of position and I'm giving away an ace...these people literally call down and I want to look at the flop...I'd prob raise if just one limped). BB checks. Flop is Ah 3h 5h. I check...checked to the button who bets, I raise. Others fold. Button calls. Turn is the Kc. Ah 3h 5h Kc. I bet, he calls. River is the 8h. Now what. Can I be winning this? What's your plan? Bet and fold to a raise? Check-call? Check-fold? Why? What about the rest of the hand?

Thanks,
Jeff
