Help me play my Aces, BB is going to 4-bet three players that put 5BBs

[Adrian20XX]

Hello,

I'm the BB, and I have to decide what to do in here.
My image on the table should be a tight player that didn't get out of line, altough once I raised with 54s on the button got called, and checked it to the river where rivered a straight and bet it.
What would you do and why?

TIA & Regards ...
