I flop one of the best hands I can after a fairly loose call here pre against two passive fish, but figure I should fold once button raises flop despite wanting to jam - thoughts?

Utg is 23/18 and seems positionally aware pre. Passive player post flop when clearly ahead but did spew a BI against me with ak high.

Button is 19/7/1, calls button and blinds far too often, seems to be passive post flop.
